Question 4 1 /^1 pts A nurse is collecting data on a child with a diagnosis of rheumatic fever. Which of the following questions would the nurse initially ask the mother of the child? “Has the child had any diarrhea?” “Has the child been vomiting?” “Does the child complain of chest pain?” “Has the child complained of a sore throat within the past few weeks or months?” around there. I sure hope we don't get hit by lightning!" Which is the nurse's best response? “Yes the equipment is a little scary. Can we talk about how the cardiac monitor works?” “Would you like a mild sedative to help you relax?” “I know about your concerns. Your family can stay with you every night if you want to.” “Oh don’t worry, the weather is supposed to be sunny and clear today.”
Question 6 1 /^1 pts Which action will the nurse implement to decrease the risk of clot formation in an older patient on bed rest? Encourage passive leg exercises and turning. Position pillows behind the knees. Assess peripheral pulses. Limit fluid intake. Using active or passive leg exercises for a patient on bed rest will prevent clot formation. Assessing pulses is not a preventive measure. Adequate hydration promotes fluidity of the blood and decreases the risk of clot formation. Placing pressure against the popliteal space will increase the risk of clot formation. Question 7 1 /^1 pts The patient is on the cardiac monitor undergoing a diagnostic procedure. Suddenly, the health care provider says, “The patient is having ventricular fibrillation!” Which piece of equipment is the most vital?
Temporary pacemaker Crash cart
Question 10 1 /^1 pts What will the nurse advise the patient to do to avoid the development of tolerance to nitroglycerin? Use the sublingual form only. Store the drug in a dark container, free from light and moisture. Allow for a daily 8- to 12-hour nitrate free period. Administer subsequent doses parenterally. An 8- to 12-hour nitrate free period will eliminate the development of tolerance to nitroglycerin. Route of administration and medication storage methods do not affect tolerance. the flow rate in drops per minute. 18 42 38 25 Question 11 1 /^1 pts
The nurse making the schedule for the daily dose of furosemide (Lasix) would schedule the administration for which of the following times? With any meal At bedtime In the morning Late in the afternoon Diuretics should be scheduled for morning administration to avoid causing the patient nocturia. Question 12 1 /^1 pts The nurse is aware that the symptoms of an impending myocardial infarction (MI) differ in women because acute chest pain is not present. Women are frequently misdiagnosed as having: menopausal complications. hepatitis A. indigestion. urinary infection.
Incorrect Decreased activity and rest Allowing moderate activity if heart rate is not above 100 Activity as tolerated Monitoring vital signs during ambulation During the acute phase, it is essential to maintain the patient on decreased activity and provide a calm, quiet environment. Question 15 0 /^1 pts The client with hypertension has been prescribed a low- sodium diet. The nurse teaching this client about foods that are allowed should plan to include which of the following in a list provided to the client? Boiled shrimp Tomato soup Summer squash Instant oatmeal
Question 16 1 /^1 pts The home health nurse caring for a patient with infective endocarditis overhears the patient making a dental appointment for an extraction next month. Which question is most important for the nurse to ask? “Do you have a toothache?” “Have you contacted your physician about your dental appointment?” “Do you think you should wait that long for your tooth extraction?’ “Is your dentist board certified?” Rationale: Foods that are lower in sodium are fruits and vegetables (“summer squash”) because they do not contain physiological saline. Highly processed or refined foods (“tomato soup” and “instant oatmeal”) are higher in sodium unless they are specifically noted as “low sodium.” Saltwater fish and shellfish are higher in sodium. Test-Taking Strategy: Begin to answer this question by eliminating “boiled shrimp” as being highest in sodium. Eliminate the other incorrect options because they are processed foods. Review the foods that are high and low in sodium if you had difficulty with this question.
Incorrect
Incorrect A trauma patient arrives in the emergency department via EMS. He is bleeding profusely. A medical alert bracelet indicates that he is on heparin therapy. The nurse will most likely administer which medication that counteracts the action of heparin? Vitamin K Protamine sulfate Enoxaparin (Lovenox) Warfarin sodium (Coumadin) Protamine sulfate is the antidote to heparin. With the patient’s risk of fluid volume deficit as a result of trauma, the primary intervention would be to counteract the effects of heparin to prevent hemorrhage. Warfarin is an anticoagulant and would not counteract hemorrhage. Lovenox is chemically related to heparin and would not counteract hemorrhage. Vitamin K is used to control the bleeding that results from use of warfarin (Coumadin), not heparin. Question 19 0 /^1 pts Which nursing assessment confirms that the angiotensin II receptor blocker (ARB) that a patient is taking is effective? Weight loss of more than 2 lb/wk. LDL cholesterol levels have decreased.
Question 21 1 /^1 pts The nurse notes a run of three ventricular contractions (PVC) that are not preceded by a P wave. This particular arrhythmia can progress into: atrial fibrillation and possible emboli. ventricular tachycardia and death. sinus tachycardia and syncope. sinus bradycardia and fatigue. PVCs are capable of progressing into ventricular tachycardia and death. “Place one nitro tablet under your tongue. If a burning sensation and headache occur, call your doctor immediately.” Sit and stand slowly after taking nitroglycerin. Place nitroglycerin tablets under the tongue at the onset of anginal pain; the second tablet can be taken after 5 minutes and the third tablet after another 5 minutes if pain is unrelieved. Then, if pain is not relieved, go to the hospital. Question 22 1 /^1 pts
