Graded A+ A 63-year-old woman whose husband died 2 months ago says to the visiting nurse, "My daughter came over yesterday to help me move my husband's things out of our bedroom, and I was so angry with her for moving his slippers from where he always kept them under his side of our bed. She doesn't know how much I'm hurting." Which statement by the nurse would be therapeutic? 1-"I know just how you feel because I lost my husband last summer." 2-"It's OK to grieve and be angry with your daughter and anyone else for a time." 3-"You need to focus on the many good years you both enjoyed together and move on." 4-"Although it's a troubling time for you, try to focus on your children and grandchildren." - ANS2-"It's OK to grieve and be angry with your daughter and anyone else for a time." The therapeutic statement is the one that gives the client permission to grieve and acknowledges that anger is part of loss and that it may be aimed at the people who are trying most to help and are closest. Options 1, 3, and 4 are all nontherapeutic. They do not encourage the client to express feelings. A child seen in the clinic is found to have rubeola (measles), and the mother asks the nurse how to care for the child. The nurse should tell the mother to implement which action? 1-Keep the child in a room with dim lights. 2-Give the child warm baths to help prevent itching. 3-Allow the child to play outdoors because sunlight will help the rash. 4-Take the child's temperature every 4 hours and administer 1 baby aspirin for fever. - ANS1-Keep the child in a room with dim lights. A nursing consideration in rubeola is eye care. The child usually has photophobia, so the nurse should suggest that the parent keep the child out of brightly lit areas. Warm baths and sunlight will aggravate itching. Additionally, the child needs to rest. Children with viral infections are not to be given aspirin because of the risk of Reye's syndrome. A client has a prescription for continuous monitoring of oxygen saturation by pulse oximetry for a preoperative client. The nurse should perform which best action to ensure accurate readings on the oximeter? 1-Apply the sensor to a finger that is cool to the touch. 2-Apply the sensor to a finger with very dark nail polish. 3-Ask the client to limit motion in the hand attached to the pulse oximeter. 4-Place the sensor distal to an intravenous (IV) site with a continuous IV infusion. - ANS3-Ask the client to limit motion in the hand attached to the pulse oximeter. Several factors can interfere with the reading of accurate oxygen saturation levels on a pulse oximeter. To ensure accurate readings, the nurse should ask the client to limit motion of the area attached to the sensor. The nurse should apply the device to a warm area because hypotension, hypothermia, and vasoconstriction interfere with blood flow to the area. The nurse needs to know that very dark nail polish (black, brown-red, blue, green) interferes with accurate measurement. The nurse also should avoid placing the sensor distal to any invasive arterial or venous catheters, pressure dressings, or blood pressure cuffs. A client in the postpartum unit complains of sudden, sharp chest pain. The client is tachycardic, and the respiratory rate is increased. The health care provider diagnoses a pulmonary embolism. Which actions should the nurse plan to take? Select all that apply. 1-Administer oxygen. 2-Assess the blood pressure. 3-Start an intravenous (IV) line. 4-Prepare to administer morphine sulfate. 5-Place the client on bed rest in a supine position. 6-Prepare to administer warfarin sodium (Coumadin). - ANS1- Administer oxygen. 2-Assess the blood pressure. 3-Start an intravenous (IV) line. 4- crackles. The signs and symptoms of a fluid imbalance depend on the type of imbalance the client is experiencing. A client who has just received a diagnosis of asthma says to the nurse, "This condition is just another nail in my coffin." Which response by the nurse is therapeutic? 1-"Do you think that having asthma will kill you?" 2-"You seem very distressed over learning you have asthma." 3-"I'm not going to work with you if you can't view this as a challenge rather than a 'nail in your coffin.'" 4-"Asthma is a very treatable condition. It is important to properly administer your medications. Let's practice with your inhalant." - ANS2-"You seem very distressed over learning you have asthma." Clients who have learned that they have a chronic illness may exhibit denial, anger, or sarcasm because of fear associated with the chronic illness. It is important for the nurse to convey an accepting attitude to enhance mutual respect and trust. Option 1 reflects and paraphrases the client's words but is somewhat sarcastic. Option 3 is punitive in its approach, threatens the client, and sarcastically quotes the client's words. Option 4 lectures the client and does not deal directly with expressed concerns. A client who has received a kidney transplant is taking azathioprine (Imuran), and the nurse provides instructions about the medication. Which statement by the client would indicate a need for further instruction? 1-"I need to watch for signs of infection." 2-"I need to discontinue the medication after 14 days of use." 3-"I can take the medication with meals to minimize nausea." 4-"I need to call the health care provider if more than one dose is missed." - ANS2-"I need to discontinue the medication after 14 days of use." Azathioprine is an immunosuppressant medication that is taken for life. Because of the effects of the medication, the client must watch for signs of infection, which are to be reported immediately to the health care provider. The medication may be taken with meals to minimize nausea. The client should also call the health care provider if more than one dose is missed. A client who is receiving intravenous (IV) fluid therapy complains of burning and a feeling of tightness at the IV insertion site. On assessment, the nurse detects coolness and swelling at the site and notes that the IV rate has slowed. The nurse determines that which complication has occurred? - ANS1-Infection 2-Phlebitis 3-Infiltration 4- Thrombosis An infiltrated IV line is one that has dislodged from the vein and is lying in subcutaneous tissue. Pallor, coolness, and swelling at the IV site result when IV fluid is deposited in the subcutaneous tissue. When the pressure in the tissues exceeds the pressure in the tubing, the flow of IV solution will slow down or stop. The corrective action is to remove the catheter and start a new IV line at another site. The conditions identified in options 1, 2, and 4 are likely to be accompanied by warmth at the site, not coolness. A client with angina pectoris is experiencing chest pain that radiates down the left arm. The nurse administers a sublingual nitroglycerin tablet to the client. The client's pain is unrelieved, and the nurse determines that the client needs another nitroglycerin tablet. Which vital sign is the most important for the nurse to check before administering the medication? 1-Temperature 2- Respirations 3-Blood pressure 4-Radial pulse rate - ANS3-Blood pressure Nitroglycerin acts directly on the smooth muscle of the blood vessels, causing relaxation and dilation. As a result, hypotension can occur. The nurse would check the client's blood pressure before administering the second nitroglycerin tablet. Although the respirations and apical pulse may be checked, these vital signs are not affected by this medication. The temperature also is not associated with administration of this medication. A client with portal-systemic encephalopathy is receiving oral lactulose (Chronulac) daily. The nurse should check which item to determine the effectiveness of this medication? 1-Lung sounds 2-Blood pressure 3- Blood ammonia level 4-Serum potassium level - ANS3-Blood ammonia level Lactulose is a hyperosmotic laxative and ammonia detoxicant. It is used to prevent or treat portal-systemic encephalopathy, including hepatic precoma and coma. It also is used to treat constipation. The medication retains ammonia in the colon (decreases the blood ammonia concentration), producing an osmotic effect. It promotes increased peristalsis and bowel evacuation, expelling ammonia from the colon. This medication has no effect on lung sounds, the blood pressure, or the serum potassium level. A health care provider writes a prescription for digoxin (Lanoxin), 0.25 mg daily. The nurse teaches the client about the medication and tells the client that it is most important to be sure to implement which measure? 1-Count the radial and carotid pulses every morning. 2-Check the blood pressure every morning and evening. 3-Stop taking the medication if the pulse is faster than 100 beats/min. 4- Withhold the medication, and call the health care provider if the pulse is slower than 60 beats/min. - ANS4-Withhold the medication, and call the health care provider if the pulse is slower than 60 beats/min. An important component of taking digoxin is monitoring the pulse rate; however, it is not necessary for the client to take both radial and carotid pulses. It is also unnecessary for the client to check the blood pressure every morning and evening because the medication does not directly affect blood pressure. It is most important for the client to know the guidelines related to withholding the medication and calling the health care provider. The client should not stop taking the medication. A hospitalized client with a diagnosis of schizophrenia who is experiencing delusions says to the nurse, "I know that the mask. 4-Document the findings and continue to monitor fetal patterns - ANS4- Document the findings and continue to monitor fetal patterns Early deceleration of the FHR refers to a gradual decrease in the heart rate, followed by a return to baseline, in response to compression of the fetal head. It is a normal and benign finding. Because early decelerations are considered benign, interventions are not necessary. Therefore, options 1, 2, and 3 are unnecessary. A nurse is assessing a dark-skinned client for the presence of petechiae. Which body area is the best for the nurse to check in this client? 1-Sclera 2-Oral mucosa 3-Soles of the foot 4-Palms of the hand - ANS2-Oral mucosa In a dark-skinned client, petechiae are best observed in the conjunctivae and oral mucosa. Jaundice would best be noted in the sclera of the eye. Cyanosis is best noted on the palms of the hands and soles of the feet. A nurse is assessing a woman in the second trimester of pregnancy who was admitted to the maternity unit with a suspected diagnosis of abruptio placentae. Which finding would the nurse expect to note if abruptio placentae is present? 1-Soft uterus 2-Abdominal pain 3-Nontender uterus 4-Painless vaginal bleeding - ANS2- Abdominal pain Classic signs and symptoms of abruptio placentae include vaginal bleeding, abdominal pain, and uterine tenderness and contractions. Mild to severe uterine hypertonicity is present. Pains is mild to severe and either localized or diffuse over one region of the uterus, with a board-like abdomen. Painless vaginal bleeding and a soft, nontender uterus in the second or third trimester of pregnancy are signs of placenta previa. A nurse is assigned to care for a client who is experiencing episodes of postural hypotension. Which action should the nurse take to ensure safety while transferring the client from the bed to the chair? 1-Arrange for a transfer board to be used. 2-Perform the transfer using a hydraulic lift only. 3-Put the client's shoes on so that the client will not slip on the floor during the transfer. 4- Allow the client to dangle the legs in a sitting position on the bed before transfer to a chair. - ANS4-Allow the client to dangle the legs in a sitting position on the bed before transfer to a chair. Having the client sit on the side of the bed before transfer allows the body to adjust to position changes, thereby avoiding a fall resulting from postural hypotension. The nurse should remain with the client and assist in the transfer to the chair. Options 1 and 2 are not necessary. Although option 3 is an important measure, it is not related to preventing postural hypotension. A nurse is checking lochia discharge in a woman in the immediate postpartum period. The nurse notes that the lochia is bright red and contains some small clots. Based on this data, the nurse should make which interpretation? 1-The client is hemorrhaging. 2- The client needs to increase oral fluids. 3-The client is experiencing normal lochia discharge. 4-The client's health care provider needs to be notified of the finding. - ANS3-The client is experiencing normal lochia discharge. Lochia, the uterine discharge present after birth, initially is bright red and may contain small clots. During the first 2 hours after birth, the amount of uterine discharge should be approximately that of a heavy menstrual period. After that time, the lochial flow should steadily decrease, and the color of the discharge should change to a pinkish red or reddish brown. Because this is a normal, expected occurrence, options 1, 2, and 4 are incorrect. A nurse is gathering data from a client with a phobia. The client tells the nurse that he consistently avoids attending community functions because he fears that he will be asked to speak publicly to the members. On the basis of this information, the nurse determines that the client is experiencing which condition? 1- Nyctophobia 2-Social phobia Agoraphobia Claustrophobia - ANS2-Social phobia Social phobias are characterized by severe anxiety or fear provoked by exposure to a social situation or a performance situation. Fear of public speaking is the most common social phobia. Nyctophobia is a fear of darkness. Agoraphobia is a fear of open spaces. Claustrophobia is a fear of closed places. A nurse is monitoring a 7- year-old child who sustained a head injury in a motor vehicle crash for signs of increased intracranial pressure (ICP). The nurse should assess the child frequently for which early sign of increased ICP? 1-Nausea 2-Papilledema 3-Decerebrate posturing 4-Alterations in pupil size - ANS1-Nausea Nausea is an early sign of increased ICP. Late signs of increased ICP include a significant decrease in level of consciousness, Cushing's triad (increased systolic blood pressure and widened pulse pressure, bradycardia, and irregular respirations), and fixed and dilated pupils. Other late signs include decreased motor response to command, decreased sensory response to painful stimuli, posturing, Cheyne-Stokes respirations, and papilledema. A nurse is monitoring a newborn infant who has been circumcised. The nurse notes that the infant has a temperature of 100.6° F and that the dressing at the circumcised area is saturated with a foul-smelling drainage. Which is the priority nursing action? 1- Reinforce the dressing. 2-Document the findings. 3-Contact the health care provider. 4-Swab the drainage and send the sample to the laboratory for culture. - ANS3- Contact the health care provider. Complications after circumcision include bleeding, failure to urinate, displacement of the Plastibell, and infection (indicated by a fever and a purulent or foul-smelling drainage). If signs of infection occur, the health care provider is notified. The nurse would change, not reinforce, the dressing; reinforcing the dressing leaves the foul smelling drainage in contact with the surgical site. The nurse would document the findings, but this is not the priority item. The health care to an infant with heart failure. Before administering the medication, the nurse double-checks the dose, counts the apical heart rate for 1 full minute, and obtains a rate of 88 beats/minute. Based on this finding, which is the appropriate nursing action? 1-Withhold the medication. 2-Administer the medication. 3-Double-check the apical heart rate and administer the medication. 4-Check the blood pressure and respirations and administer the medication. - ANS1-Withhold the medication. Digoxin is a cardiac glycoside that is used to treat heart failure. A primary concern is digoxin toxicity and the nurse needs to monitor closely for signs of toxicity and monitor digoxin blood levels. The medication is effective within a narrow therapeutic digoxin range (1.0 to 2.0 ng/mL). Safety in administration is achieved by double- checking the dose and counting the apical heart rate for 1 full minute. If the heart rate is less than 100 beats/minute in an infant, the nurse would withhold the dose and contact the health care provider. Therefore, options 2, 3, and 4 are incorrect actions; it would be harmful to administer the medication. A nurse is preparing to care for a newborn who has respiratory distress syndrome. Which initial action should the nurse plan to best facilitate bonding between the newborn and the parents? 1-Encourage the parents to touch their newborn. 2-Identify specific caregiving tasks that may be assumed by the parents. 3-Explain the equipment that is used and how it functions to assist their newborn. 4-Give the parents pamphlets that will help them understand their newborn's condition. - ANS1-Encourage the parents to touch their newborn. The best initial action to begin the attachment process and promote bonding is to encourage the parents to touch their newborn. The parents' initial need is to become acquainted with their newborn. Option 2 may be frightening to the parents because of the condition of the newborn and the unfamiliarity of high-risk newborn care practices. This option will be appropriate later, as the newborn's condition becomes stable. Option 3 is important but is not specific to parent-newborn bonding activities. Option 4 is inappropriate initially. Requiring parents to focus on pamphlets or literature does not enhance the parent- newborn bond. A nurse is providing home care instructions to the mother of an infant who has just been found to have hemophilia. The nurse should tell the mother that care of the infant should include which appropriate measure? 1-Use aspirin for pain relief. 2-Pad crib rails and table corners. 3-Use a soft toothbrush for dental hygiene. 4-Use a generous amount of lubricant when taking a temperature rectally. - ANS2-Pad crib rails and table corners. Establishment of an age-appropriate, safe environment is of paramount importance for hemophiliacs. Providing a safe environment for an infant includes padding table corners and crib rails, providing extra padding on clothes to protect the joints, observing a mobile infant at all times, and keeping items that can be pulled down onto the infant out of reach. Use of a soft toothbrush is an appropriate measure for a child with hemophilia but is not typically necessary for an infant. Rectal temperature measurements and the use of aspirin are contraindicated in hemophiliacs because of the risk of bleeding. A nurse is providing morning care to a client who has a closed chest tube drainage system to treat a pneumothorax. When the nurse turns the client to the side, the chest tube is accidentally dislodged from the chest. The nurse immediately applies sterile gauze over the chest tube insertion site. Which is the nurse's next action? 1-Call the health care provider. 2-Replace the chest tube system. 3-Obtain a pulse oximetry reading. 4-Place the client in a Trendelenburg position - ANS1-Call the health care provider. If the chest drainage system is dislodged from the insertion site, the nurse immediately applies sterile gauze over the site and calls the health care provider. The nurse would maintain the client in an upright position. A new chest tube system may be attached if the tube requires insertion, but this would not be the next action. Pulse oximetry readings would assist in determining the client's respiratory status, but the priority action would be to call the health care provider in this emergency situation. A nurse notes that a client is taking lansoprazole (Prevacid). On assessment of the client, the nurse should ask which question to determine the effectiveness of this medication? 1-"Has your appetite increased?" 2-"Are you experiencing any heartburn?" 3-"Do you have any problems with vision?" 4-"Do you experience any leg pain when walking?" - ANS2-"Are you experiencing any heartburn?" Lansoprazole is a gastric acid pump inhibitor that is used to treat gastric and duodenal ulcers, erosive esophagitis, and hypersecretory conditions. It also is used to treat gastroesophageal reflux disease (GERD). It is not used to treat problems with appetite, visual problems, or leg pain. A nurse performs an assessment of a pregnant woman who is receiving intravenous magnesium sulfate for management of preeclampsia and notes that the woman's deep tendon reflexes are absent. On the basis of this finding, the nurse should make which interpretation? 1-The infusion rate needs to be increased. 2-The magnesium sulfate is effective. 3-The woman is experiencing cerebral edema. 4- Magnesium toxicity can occur as a result of magnesium sulfate therapy. - ANSSigns of magnesium sulfate toxicity relate to the central nervous system depressant effects of the medication and include respiratory depression, loss of deep tendon reflexes, sudden decrease in fetal heart rate or maternal heart rate or both, and sudden drop in blood pressure. An absence of reflexes indicates magnesium excess. The infusion rate therefore would not be increased. Hyperreflexia indicates increased cerebral After maximal inspiration, hold the breath for 10 seconds and then exhale. For optimal lung expansion with the incentive spirometer, the client should assume a semi-Fowler's or high Fowler's position. The mouthpiece should be covered completely and tightly while the client inhales slowly, with a constant flow through the unit. When maximal inspiration is reached, the client should hold the breath for 2 or 3 seconds and then exhale slowly A nurse reinforces medication instructions to a client who has received a kidney transplant about therapy with cyclosporine (Sandimmune). Which statement by the client would indicate a need for further instruction? 1-"I need to obtain a yearly influenza vaccine." 2-"I need to have dental checkups every 3 months." 3-"I need to self-monitor my blood pressure at home." 4-"I need to call the health care provider if my urine volume decreases or it becomes cloudy." - ANS1-"I need to obtain a yearly influenza vaccine." Cyclosporine is an immunosuppressant medication. Because of the effects of the medication, the client should not receive any vaccinations without first consulting the health care provider. The client should report decreased urine output or cloudy urine, which could indicate kidney rejection or infection, respectively. The client needs meticulous oral care and dental cleaning every 3 months to help prevent gingival hyperplasia. The client must be able to self-monitor blood pressure to check for the side effect of hypertension. A nurse reviews the medication history of a client and notes that the client is taking leflunomide (Arava). During assessment of the client, the nurse should ask which question to determine the effectiveness of this medication? 1-"Do you have any joint pain?" 2-"Are you having any diarrhea?" 3-"Are you experiencing heartburn?" 4-"Do you have frequent headaches?" - ANS1-"Do you have any joint pain?" Leflunomide is an immunomodulatory agent and has an anti-inflammatory action. The medication provides symptomatic relief of rheumatoid arthritis. Diarrhea can occur as a side effect of the medication. Options 2, 3, and 4 are unrelated to the action, use, or effectiveness of the medication. A postpartum woman with mastitis in the right breast complains that the breast is too sore for her to breast-feed her infant. The nurse should tell the client to implement which measure? 1-Pump both breasts and discard the milk. 2-Bottle-feed the infant on a temporary basis. 3-Breast- feed from the left breast and gently pump the right breast. 4-Stop breast-feeding from both breasts until this condition resolves. - ANS3-Breast-feed from the left breast and gently pump the right breast. A postpartum woman with mastitis in the right breast complains that the breast is too sore for her to breast-feed her infant. The nurse should tell the client to implement which measure? A registered nurse (RN) asks a licensed practical nurse (LPN) to set up a hospital room for a client who is being admitted with a diagnosis of tonic-clonic seizures and asks the LPN to institute seizure precautions. The RN checks the client's room before the arrival of the client and determines that which item placed in the room by the LPN is unsafe? 1- Restraints 2-Nasal cannula 3-Suction catheter 4-Padding for side rails - ANS1- Restraints Seizure precautions include keeping side rails up and padded if the client has tonic-clonic seizures, ensuring that suction and oxygen equipment is available, and disabling the locks on the bathroom and room doors. Restraints are not used and can result in client injury. A woman in the third trimester of pregnancy visits the clinic for a scheduled prenatal appointment. The woman tells the nurse that she frequently has leg cramps, primarily when she is reclining. Once thrombophlebitis has been ruled out, the nurse should tell the woman to implement which measure to alleviate the leg cramps? 1-Apply heat to the affected area. 2-Take acetaminophen (Tylenol) every 4 hours. 3-Self-administer calcium carbonate tablets three times daily. 4-Purchase a chewable antacid that contains calcium and take a tablet with each meal. - ANS1-Apply heat to the affected area. Leg cramps may be a result of compression of the nerves supplying the legs by the enlarging uterus, a reduced level of diffusible serum calcium, or an increase in serum phosphorus. In the pregnant woman who complains of leg cramps, the nurse would perform further assessments to ensure that the client is not experiencing thrombophlebitis. Once this has been ruled out, the nurse would instruct the woman to place heat on the affected area, dorsiflex the foot until the spasm relaxes, or stand and walk. The health care provider may prescribe oral supplementation with calcium carbonate tablets or calcium hydroxide gel with each meal to increase the calcium level and lower the phosphorus level, but the nurse would not prescribe these or any other medications. A woman in the third trimester of pregnancy with a diagnosis of mild preeclampsia is being monitored at home. The home care nurse teaches the woman about the signs that need to be reported to the health care provider. The nurse should tell the woman to call the health care provider if which occurs? 1-Urine tests negative for protein. 2-Fetal movements are more than four per hour. 3-Weight increases by more than 1 pound in a week. 4-The blood pressure reading is ranging between 122/80 and 132/88 mm Hg. - ANS3-Weight increases by more than 1 pound in a week. The nurse would instruct the client to report any increase in blood pressure, protein in the urine, weight gain greater than 1 pound per week, or edema. The client also is taught how to count fetal movements and is instructed that decreased fetal activity (three or fewer movements per hour) may indicate fetal compromise and should be reported. After a tonsillectomy, a child is brought to the pediatric unit. ergot alkaloids. The nurse would assess the woman's blood pressure before administering the medication and would follow agency protocols regarding withholding of the medication. Options 1, 2, and 3 are items that are assessed in the postpartum period, but they are unrelated to the use of this medication. The clinic nurse reads the results of a tuberculin skin test performed on a 5-year-old child who is at low risk for contracting tuberculosis. The results indicate an area of induration measuring 10 mm. How would the nurse interpret these results? 1-Positive 2- Negative 3-Inconclusive 4-Definitive and requiring a repeat test - ANS2-Negative Induration measuring 15 mm or greater is considered a positive result in a child 4 years of age or older who has no associated risk factors. Options 1, 3, and 4 are incorrect interpretations. The mother of 6-year-old twins says to the nurse, "My mother-in-law doesn't think our children should come to the funeral service for their grandfather. What do you advise?" The nurse most appropriately responds by making which statement? 1-"What do you and your husband believe is the right thing for your children?" 2-"By all means have them attend. Not to do so would promote postmortem grief." 3-"It's a difficult decision, but given their young age, perhaps omitting the wake and just including the funeral would be best." 4-"I agree with your mother-in-law. Your mother-in-law is upset enough as it is. Tell your children that their grandfather is in heaven." - ANS1-"What do you and your husband believe is the right thing for your children?" The most therapeutic response is the one that encourages open expression of feelings and empowers the grieving relative. Values, beliefs, and practices differ depending on the client's ethnic and spiritual backgrounds, and the nurse should not push a decision based on the nurse's own belief system. Options 2, 3, and 4 are nontherapeutic. Option 2 provides incorrect information related to postmortem grieving. Options 3 and 4 offer the nurse's opinion and impose the nurse's own beliefs. The nurse instructs a client regarding pursed-lip breathing and asks the client to demonstrate the breathing technique. Which observation by the nurse would indicate that the client is performing the technique correctly? 1-The client breathes in through the mouth. 2-The client breathes out slowly through the mouth. 3-The client avoids using the abdominal muscles to breathe out. 4-The client puffs out the cheeks when breathing out through the mouth. - ANS2-The client breathes out slowly through the mouth. Pursed-lip breathing facilitates maximal expiration for clients with obstructive lung disease. The client should close the mouth and breathe in through the nose. The client then purses the lips and breathes out slowly through the mouth, without puffing the cheeks. The client should spend at least twice the amount of time breathing out that it took to breathe in. The client should use the abdominal muscles to assist in squeezing out all of the air. The client also is instructed to use this technique during any physical activity, inhale before beginning the activity, and exhale while performing the activity. The client is also instructed that he or she should never hold the breath. The nurse is assessing a client with a suspected diagnosis of hypocalcemia. Which cardiovascular manifestation would the nurse expect to note? 1-Hypotension 2-Increased heart rate 3-Bounding peripheral pulses 4-Shortened QT interval on electrocardiography (ECG) - ANS1-Hypotension Cardiovascular manifestations that occur with hypocalcemia include decreased heart rate, diminished peripheral pulses, and hypotension. On the electrocardiogram (ECG), the nurse would note a prolonged ST interval and a prolonged QT interval. The nurse is assessing a client's postoperative pain using the PQRSTU method. Using this method, which questions would the nurse ask the client? - ANSThe PQRSTU method is one method of assessing pain. With this method, the nurse asks about the following: Precipitating factors (option 6); Quality of the pain (option 3); Region or Radiation of the pain (option 1); Severity of the pain; Timing of the pain (continuous or intermittent); and How the pain affects you (option 4). Options 2 and 5 may be questions that would be asked; however, these are not a part of the PQRSTU method. The nurse is caring for a client who is receiving oxytocin (Pitocin) for induction of labor and notes a nonreassuring fetal heart rate (FHR) pattern on the fetal monitor. On the basis of this finding, the nurse should take which action first? 1-Stop the oxytocin infusion. 2-Check the client's blood pressure. 3-Check the client for bladder distention. 4-Place the client in a side-lying position - ANS1-Stop the oxytocin infusion. Oxytocin stimulates uterine contractions and is used to induce labor. If uterine hypertonicity or a nonreassuring FHR pattern occurs, the nurse needs to intervene to reduce uterine activity and increase fetal oxygenation. The oxytocin infusion is stopped, the client is placed in a side-lying position, and oxygen by face mask at 8 to 10 L/min is administered. The health care provider is notified. The nurse would monitor the client's blood pressure and intake and output; however, the nurse would first stop the infusion. The nurse is monitoring a client who has a closed chest tube drainage system. The nurse notes fluctuation of the fluid level in the water-seal chamber during inspiration and expiration. On the basis of this finding, the nurse should make which interpretation? 1-There is a leak in the system. 2-The chest tube is functioning as expected. 3-The amount of suction needs to be decreased. 4-The occlusive dressing at the insertion site needs reinforcement. - ANS2-The chest tube is functioning as expected. The presence of fluctuation of the diagnosis of heart failure. Which is the most important laboratory test result for the nurse to check before administering this medication? 1-Blood urea nitrogen 2- Cholesterol level 3-Potassium level 4-Creatinine level - ANSFurosemide is a loop diuretic. The medication causes a decrease in the client's electrolytes, especially potassium, sodium, and chloride. Administering furosemide to a client with low electrolyte levels could precipitate ventricular dysrhythmias. Options 1 and 4 reflect renal function. The cholesterol level is unrelated to the administration of this medication. The nurse is preparing to care for a client who will be arriving from the recovery room after an above-the-knee amputation. The nurse ensures that which is in the client's hospital room as a priority item? 1-Over-bed trapeze 2-Dry sterile dressings 3-Surgical tourniquet 4-Incentive spirometer - ANS3-Surgical tourniquet Monitoring for complications is an important aspect of initial postoperative care. Vital signs and pulse oximetry values are monitored closely until the client's condition stabilizes. The wound and any drains are monitored closely for excessive bleeding because hemorrhage is the primary immediate complication of amputation. Therefore a surgical tourniquet is kept at the bedside in case of acute bleeding. An over-bed trapeze increases the client's independence in self-care activities but is not a priority in the immediate postoperative period. An incentive spirometer and dry sterile dressings also should be available, but these are not priority items considering the surgical procedure that the client underwent. The nurse is preparing to care for a client with acquired immunodeficiency syndrome (AIDS). In planning infection control for this client, the nurse should implement which form of isolation to prevent the spread of the AIDS virus to others? 1-Strict isolation 2-Enteric precautions 3- Contact precautions 4-Blood and body fluid precautions - ANS4-Blood and body fluid precautions The AIDS virus is transmitted through anal, vaginal, or oral sexual contact with infected semen or vaginal secretions; through contact with infected blood or blood products; from mother to fetus during childbirth; or during breast- feeding. Blood and body fluid precautions will prevent contact with infectious matter from the AIDS virus. Strict isolation is not needed and may contribute to feelings of isolation in the client. Enteric or contact precautions alone are insufficient to prevent transmission of the AIDS virus. The nurse is preparing to care for a client with immunodeficiency.
