Typology: Exams
1 / 51
Alpha blockers -Potential drug effect? – orthostatic hypotension A patient is taking an alpha blocker as treatment for benign prostatic hyperplasia. The nurse will monitor for which potential drug effect? a. Orthostatic hypotension b. Increased blood pressure c. Decreased urine flow d. Discolored urine ANS: A Orthostatic hypotension can occur with any dose of an alpha blocker, and patients must be warned to get up slowly from a supine position. The other responses are not drug effects of alpha blockers. ZYLOPRIM (allopurinol ) – indication for gout – reduce the amount of uric acid formed by body cells .A patient with gout has been treated with allopurinol (Zyloprim) for 2 months. The nurse will monitor laboratory results for which therapeutic effect? a. Decreased uric acid levels b. Decreased prothrombin time c. Decreased white blood cell count d. Increased hemoglobin and hematocrit levels ANS: A Treatment of gout with allopurinol should result in decreased uric acid levels. The other options are incorrect.
Amiodarone (Cordarone) – Mechanism of action. The nurse is reviewing the classes of antidysrhythmic drugs. Amiodarone (Cordarone) is classified on the Vaughan Williams classification as a class III drug, which means it works by which mechanism of action? a. Blocking slow calcium channels b. Prolonging action potential duration c. Blocking sodium channels and affecting phase 0 d. Decreasing spontaneous depolarization and affecting phase ANS: B Vaughan Williams class III drugs (amiodarone, dronedarone, sotalol, ibutilide, and dofetilide) increase the action potential duration by prolonging repolarization in phase 3. The other answers are incorrect. Androgenic steroids: adverse effect – liver damage A 21-year-old male athlete admits to using androgenic steroids. The nurse tells him that which of these is a possible adverse effect of these drugs? a. Liver damage b. Renal failure c. Heart failure d. Stevens-Johnson syndrome ANS: A Peliosis of the liver, the formation of blood-filled cavities, is a potential effect of androgenic anabolic steroid therapy and may be life threatening. Other serious hepatic effects are hepatic neoplasms (liver cancer), cholestatic hepatitis, jaundice, and abnormal liver function. The other options are incorrect.
A mother brings her toddler into the emergency department and tells the nurse that she thinks the toddler has eaten an entire bottle of chewable aspirin tablets. The nurse will assess for which most common signs of salicylate intoxication in children? a. Photosensitivity and nervousness b. Tinnitus and hearing loss c. Acute gastrointestinal bleeding d. Hyperventilation and drowsiness ANS: D The most common manifestations of chronic salicylate intoxication in adults are tinnitus and hearing loss. Those in children are hyperventilation and CNS effects, such as dizziness, drowsiness, and behavioral changes A 6-year-old child who has chickenpox also has a fever of 102.9° F (39.4° C). The child’s mother asks the nurse if she should use aspirin to reduce the fever. What is the best response by the nurse? a. “It’s best to wait to see if the fever gets worse.” b. “You can use the aspirin but watch for worsening symptoms.” c. “Acetaminophen (Tylenol) should be used to reduce his fever, not aspirin.” d. “You can use aspirin but be sure to follow the instructions on the bottle.” ANS: C Aspirin is contraindicated in children with flu-like symptoms because the use of this drug has been strongly associated with Reye’s syndrome. This is an acute and potentially life-threatening condition involving progressive neurologic deficits that can lead to coma and may also involve liver damage. Acetaminophen is appropriate for this patient. The other responses are incorrect.
A patient has used enteric aspirin for several years as treatment for osteoarthritis. However, the symptoms are now worse and she is given a prescription for a nonsteroidal anti-inflammatory drug and misoprostol (Cytotec). The patient asks the nurse, “Why am I now taking two pills for arthritis?” What is the nurse’s best response? a. “Cytotec will also reduce the symptoms of your arthritis.” b. “Cytotec helps the action of the NSAID so that it will work better.” c. “Cytotec reduces the mucous secretions in the stomach, which reduces gastric irritation.” d. “Cytotec may help to prevent gastric ulcers that may occur in patients taking NSAIDs.” ANS: D Cytotec inhibits gastric acid secretions and stimulates mucous secretions; it has proved successful in preventing the gastric ulcers that may occur in patients taking NSAIDs During assessment of a patient with osteoarthritis pain, the nurse knows that which condition is a contraindication to the use of nonsteroidal anti-inflammatory drugs (NSAIDs)? a. Renal disease b. Diabetes mellitus c. Headaches d. Rheumatoid arthritis ANS: A Contraindications to NSAIDs include known drug allergy and conditions that place a patient at risk for bleeding, such as vitamin K deficiency, and peptic ulcer disease. Patients with documented aspirin allergy must not receive NSAIDs. Other common contraindications are those that apply to most drugs, including severe renal or hepatic disease. The other options are not contraindications.
A 75-year-old woman has been given a nonsteroidal anti-inflammatory drug (an NSAID for the treatment of rheumatoid arthritis. The nurse is reviewing the patient’s medication history and notes that which types of medications could have an interaction with the NSAID? (Select all that apply.) a. Antibiotics b. Decongestants c. Anticoagulants d. Beta blockers e. Diuretics f. Corticosteroids ANS: C, E, F anticoagulants taken with NSAIDs may cause increased bleeding tendencies because of platelet inhibition and hypoprothrombinemia. NSAIDs taken with diuretics may cause reduced hypotensive and diuretic effects. NSAIDs taken with corticosteroids may cause increased ulcerogenic effects. See Table 44-5. The other options are incorrect. Atenolol (Tenormin) Teaching S/S of HF? Care planning: potential human needs statements?
During therapy with a beta blocker, the patient notices that she has swollen feet, has gained 3 pounds within 2 days, feels short of breath even when walking around the house, and has been dizzy. The nurse suspects that which of these is occurring? a. The patient is experiencing an allergic reaction. b. The patient may be developing heart failure. c. More time is needed for the patient to see a therapeutic response to the drug. d. The patient is experiencing expected adverse effects of the drug. ANS: B Even though some beta blockers may be used for the treatment of some types of heart failure, the patient needs to be assessed often for the development of heart failure, a potential adverse effect of the drugs. These symptoms do not indicate expected adverse effects, an allergic reaction, or a therapeutic response. When counseling a male patient about the possible adverse effects of antihypertensive drugs, the nurse will discuss which potential problem? a. Impotence b. Bradycardia c. Increased libido d. Weight gain ANS: A Sexual dysfunction is a common complication of antihypertensive medications and may be manifested in men as decreased libido or impotence. The other options are incorrect.
The nurse is creating a plan of care for a patient with a new diagnosis of hypertension. Which is a potential nursing diagnosis for the patient taking antihypertensive medications? a. Diarrhea b. Sexual dysfunction c. Urge urinary incontinence d. Impaired memory ANS: B Sexual dysfunction is a potential nursing diagnosis related to possible adverse effects of antihypertensive drug therapy. The other nursing diagnoses are not appropriate. A patient with primary hypertension is prescribed drug therapy for the first time. The patient asks how long drug therapy will be needed. Which answer by the nurse is the correct response? a. “This therapy will take about 3 months.” b. “This therapy will take about a year.” c. “This therapy will go on until your symptoms disappear.” d. “Therapy for high blood pressure is usually lifelong.” ANS: D There is no cure for the disease, and treatment will be lifelong. The other answers are not appropriate.
Captopril (Capoten) How is this drug activated? Advantage of this drug characteristic? A patient with severe liver disease is receiving the angiotensin-converting enzyme (ACE) inhibitor, captopril (Capoten). The nurse is aware that the advantage of this drug for this patient is which characteristic? a. Captopril rarely causes first-dose hypotensive effects. b. Captopril has little effect on electrolyte levels. c. Captopril is a prodrug and is metabolized by the liver before becoming active. d. Captopril is not a prodrug and does not need to be metabolized by the liver before becoming active. ANS: D A prodrug relies on a functioning liver to be converted to its active form. Captopril is not a prodrug, and therefore it would be safer for the patient with liver dysfunction. A patient with type 2 diabetes mellitus has been found to have trace proteinuria. The prescriber writes an order for an angiotensin-converting enzyme (ACE) inhibitor. What is the main reason for prescribing this class of drug for this patient? a. Cardioprotective effects b. Renal protective effects c. Reduces blood pressure d. Promotes fluid output ANS: B ACE inhibitors have been shown to have a protective effect on the kidneys because they reduce glomerular filtration pressure. This is one reason that they are among the cardiovascular drugs of choice for diabetic patients. The other drugs do not have this effect.
Ciplatin AE? When giving cisplatin (Platinol-AQ), the nurse is aware that the major dose-limiting effect of this drug is which condition? a. Alopecia b. Kidney damage c. Cardiotoxicity d. Stomatitis ANS: B Cisplatin may cause nephrotoxicity, and the patient’s renal function must be monitored closely while on this drug. Ensuring hydration will help to prevent nephrotoxicity. When a patient is receiving cisplatin (Platinol-AQ) chemotherapy, the nurse will monitor for which adverse effects? (Select all that apply.) a. Tinnitus b. Heart failure c. Hearing loss d. Elevated blood urea nitrogen and creatinine levels e. Numbness or tingling in the extremities f. Elevated glucose and ketone levels ANS: A, C, D, E Cisplatin can cause nephrotoxicity, ototoxicity, and peripheral neuropathy. Nephrotoxicity is manifested by rising blood urea nitrogen and creatinine levels; ototoxicity is manifested by tinnitus, hearing loss, and dizziness; peripheral neuropathy is manifested by numbness or tingling of the extremities
Flexeril (cyclobenzaprine) Indication? A patient is recovering from a minor automobile accident that occurred 1 week ago. He is taking cyclobenzaprine (Flexeril) for muscular pain and goes to physical therapy three times a week. Which nursing diagnosis would be appropriate for him? a. Risk for injury related to decreased sensorium b. Risk for addiction related to psychologic dependency c. Decreased fluid volume related to potential adverse effects d. Disturbed sleep pattern related to the drug’s interference with REM sleep A ANS: A Musculoskeletal relaxants have a depressant effect on the CNS; thus, the patient needs to be taught the importance of taking measures to minimize self-injury and falls related to decreased sensorium. “Risk for addiction” is not a NANDA nursing diagnosis. The other nursing diagnoses are not appropriate for this situation. The nurse notes in the patient’s medication history that the patient is taking cyclobenzaprine (Flexeril). Based on this finding, the nurse interprets that the patient has which disorder? a. A musculoskeletal injury b. Insomnia c. Epilepsy d. Agitation ANS: A Cyclobenzaprine (Flexeril) is the muscle relaxant most commonly used to reduce spasms following musculoskeletal injuries. It is not appropriate for insomnia, epilepsy, or agitation.

Check the radial pulse for 1 full minute. d. Withhold the dose, and notify the prescriber. ANS: D Digoxin doses are held and the prescriber notified if the apical pulse is 60 beats/min or lower or is higher than 100 beats/min. The other options are incorrect. A patient is taking digoxin (Lanoxin) and a loop diuretic daily. When the nurse enters the room with the morning medications, the patient states, “I am seeing a funny yellow color around the lights.” What is the nurse’s next action? a. Assess the patient for symptoms of digoxin toxicity. b. Withhold the next dose of the diuretic. c. Administer the digoxin and diuretic together as ordered. d. Document this finding, and reassess in 1 hour. ANS: A Seeing colors around lights is one potential indication of developing digoxin toxicity. If a patient complains of this, the nurse needs to assess for other signs and symptoms of digoxin toxicity including bradycardia, headache, dizziness, confusion, nausea, and blurred vision, and then notify the prescriber. Administering the drug or withholding the diuretic are incorrect options.
A patient has been taking digoxin at home but took an accidental overdose and has developed toxicity. The patient has been admitted to the telemetry unit, where the physician has ordered digoxin immune Fab (Digifab). The patient asks the nurse why the medication is ordered. What is the nurse’s best response? a. “It will increase your heart rate.” b. “This drug helps to lower your potassium levels.” c. “It helps to convert the irregular heart rhythm to a more normal rhythm.” d. “This drug is an antidote to digoxin and will help to lower the blood levels.” ANS: D Digoxin immune Fab (Digifab) is the antidote for a severe digoxin overdose. It is given intravenously. The other options are incorrect A patient has a digoxin level of 1.1 ng/mL. Which interpretation by the nurse is correct? a. It is below the therapeutic level. b. It is within the therapeutic range. c. It is above the therapeutic level. d. It is at a toxic level. ANS: B The normal therapeutic drug level of digoxin is between 0.5 and 2 ng/mL. The other options are incorrect When administering digoxin immune Fab (Digibind) to a patient with severe digoxin toxicity, the nurse knows that each vial can bind with how much digoxin? a. 0.5 mg b. 5 mg c. 5.5 mg d. 15 mg ANS: A One vial of digoxin immune Fab binds 0.5 mg of digoxin. The other options are incorrect

Promoting relaxation ANS: B Common uses of echinacea include stimulation of the immune system, antisepsis, treatment of viral infections and influenza-like respiratory tract infections, and promotion of the healing of wounds and chronic ulcerations. The other options are incorrect. Epinephrine Indications? The nurse is administering a stat dose of epinephrine. Epinephrine is appropriate for which situation? a. Severe hypertension b. Angina c. Cardiac arrest d. Tachycardia ANS: C Treatment of cardiac arrest is an indication for the use of epinephrine. The other options are not indications for epinephrine. A hospitalized patient is experiencing a severe anaphylactic reaction to a dose of intravenous penicillin. Which drug will the nurse expect to use to treat this condition? a. Ephedra b. Epinephrine c. Phenylephrine d. Pseudoephedrine ANS: B Epinephrine is the drug of choice for the treatment of anaphylaxis. The other drugs listed are incorrect choices.
Epoetin alfa (Epogen) Route of administration? What’s the difference between Epoetin & Aranesp? A patient has been receiving epoetin alfa (Epogen) for severe iron-deficiency anemia. Today, the provider changed the order to darbepoetin (Aranesp). The patient questions the nurse, “What is the difference in these drugs?” Which response by the nurse is correct? a. “There is no difference in these two drugs.” b. “Aranesp works faster than Epogen to raise your red blood cell count.” c. “Aranesp is given by mouth, so you will not need to have injections.” d. “Aranesp is a longer-acting form, so you will receive fewer injections.” ANS: D Darbepoetin (Aranesp) is longer-acting than epoetin alfa (Epogen); therefore, fewer injections are required. The other options are incorrect. Finasteride (Proscar) Nurse handling considerations? A patient is receiving finasteride (Proscar) for treatment of benign prostatic hyperplasia. The nurse will tell him that a possible effect of this medication is: a. alopecia. b. increased hair growth. c. urinary retention. d. increased prostate size. ANS: B Finasteride is given to reduce prostate size in men with benign prostatic hyperplasia. It has been noted that men taking this medication experience increased hair growth. The other options are incorrect.
During the administration of finasteride (Proscar), the nurse must remember which important precaution? a. It must be taken on an empty stomach. b. It must not be handled by pregnant women. c. It is given by deep intramuscular injection to avoid tissue irritation. d. The patient needs to be warned that alopecia is a common adverse effect. ANS: B Finasteride must not be handled by pregnant women because of its teratogenic effects. It is taken orally and without regard to meals. The other options are incorrect. Fluorescein sodium (AK-Fluor) Indication? A patient with an eye injury requires an ocular examination to detect the presence of a foreign body. The nurse anticipates that which drug will be used for this examination? a. Phenylephrine (Neo-Synephrine) b. Fluorescein sodium (AK-Fluor) c. Atropine sulfate (Isopto Atropine) d. Olopatadine (Patanol) ANS: B Fluorescein sodium is an ophthalmic diagnostic dye used to identify corneal defects and to locate foreign objects in the eye. Phenylephrine is an ocular decongestant; atropine sulfate has mydriatic and cycloplegic effects, which are useful for examining the inner eye structures; olopatadine is an ophthalmic antihistamine.
Folic Acid Indication? Teaching to pregnant women? The nurse is administering folic acid to a patient with a new diagnosis of anemia. Which statement about treatment with folic acid is true? a. Folic acid is used to treat any type of anemia. b. Folic acid is used to treat iron-deficiency anemia. c. Folic acid is used to treat pernicious anemia. d. The specific cause of the anemia needs to be determined before treatment. ANS: D Folic acid should not be used to treat anemias until the underlying cause and type of anemia have been identified. Administering folic acid to a patient with pernicious anemia may correct the hematologic changes of anemia, but the symptoms of pernicious anemia (which is due to a vitamin B12 deficiency, not a folic acid deficiency) may be deceptively masked. The other options are incorrect A woman who is planning to become pregnant should ensure that she receives adequate levels of which supplement to reduce the risk for fetal neural tube defects? a. Vitamin B b. Vitamin D c. Iron d. Folic acid ANS: D It is recommended that administration of folic acid be begun at least 1 month before pregnancy and continue through early pregnancy to reduce the risk for fetal neural tube defects.
Glucosamine-chondroitin Drug interactions? Pt diagnoses that cause concern for interaction? A patient calls the clinic to ask about taking a glucosamine-chondroitin supplement for arthritis. The nurse reviews the medication history and notes that there will be a concern for drug interactions if the patient is also taking medications for which disorder? a. Type 2 diabetes mellitus b. Hypothyroidism c. Hypertension d. Angina ANS: A The glucosamine in glucosamine-chondroitin supplements may cause an increase in insulin resistance, necessitating the need for higher doses of oral hypoglycemics or insulin. Guaifenesin (Humibid) Indications? MOA? Pt Teaching? A patient is taking guaifenesin (Humibid) as part of treatment for a sinus infection. Which instruction will the nurse include during patient teaching? a. Force fluids to help loosen and liquefy secretions. b. Report clear-colored sputum to the prescriber. c. Avoid driving a car or operating heavy machinery because of the sedating effects. d. Report symptoms that last longer than 2 days. A NS: A Forcing fluids helps to loosen and liquefy secretions. The patient must be fully aware that any fever, chest tightness, change in sputum from clear to colored, difficult or noisy breathing, activity intolerance, or weakness needs to be reported. The patient must also report to the prescriber a fever of higher than 100.4° F (38° C) or symptoms that last longer than 3 to 4 days. Decongestants do not cause sedation, and therefore the patient does not need to avoid driving a car or operating heavy machinery.
A patient with a tracheostomy has difficulty removing excessive, thick mucus from the respiratory tract. The nurse expects that which drug will be ordered to aid in the removal of mucus? a. Guaifenesin (Humibid) b. Benzonatate (Tessalon Perles c. Diphenhydramine (Benadryl) d. Dextromethorphan (Robitussin DM) ANS: A Expectorants such as guaifenesin work to loosen and thin sputum and the bronchial secretions, thereby indirectly diminishing the tendency to cough. The other drugs listed do not have this effect Heparin Which lab to monitor? Antidote? A patient is receiving heparin therapy as part of the treatment for a pulmonary embolism. The nurse monitors the results of which laboratory test to check the drug’s effectiveness? a. Bleeding times b. Activated partial thromboplastin time (aPTT) c. Prothrombin time/international normalized ratio (PT/INR) d. Vitamin K levels ANS: B Ongoing aPTT values are used to monitor heparin therapy. PT/INR is used to monitor warfarin therapy. The other two options are not used to monitor anticoagulant therapy. A patient has received an overdose of intravenous heparin, and is showing signs of excessive bleeding. Which substance is the antidote for heparin overdose? a. Vitamin E b. Vitamin K c. Protamine sulfate d. Potassium chloride ANS: C Protamine sulfate is a specific heparin antidote and forms a complex with heparin, completely reversing its anticoagulant properties. Vitamin K is the antidote for warfarin (Coumadin) overdose. The other options are incorrect.
Ibutilide (Corvert) Indication? The nurse notes in the patient’s medication orders that the patient will be taking ibutilide (Corvert). Based on this finding, the nurse interprets that the patient has which disorder? a. Ventricular ectopy b. Atrial fibrillation c. Supraventricular tachycardia d. Bradycardia ANS: B Ibutilide (Corvert) is one of two class III antidysrhythmic drugs available for rapid conversion of these atrial fibrillations and atrial flutters into normal sinus rhythm. Irinotecan (Camptosar) Teaching? Potential lifethreatening A/E? A patient is receiving irinotecan (Camptosar), along with other antineoplastic drugs, as treatment for ovarian cancer. The nurse will monitor for which potentially life-threatening adverse effect that is associated with this drug? a. Severe stomatitis b. Bone marrow suppression c. Delayed-onset cholinergic diarrhea d. Immediate and severe nausea and vomiting ANS: C In addition to producing hematologic adverse effects, irinotecan has been associated with severe diarrhea, known as cholinergic diarrhea, which may occur during infusions. Delayed diarrhea may occur 2 to 10 days after infusion of irinotecan. It is recommended that this condition be treated with atropine unless use of that drug is strongly contraindicated. This diarrhea can be severe and even life threatening
Isonazid (INH) Why would pyridoxine be given concurrently? What s/s should pt report to prescriber? The nurse is preparing to administer morning medications to a patient who has been newly diagnosed with tuberculosis. The patient asks, “Why do I have to take so many different drugs?” Which response by the nurse is correct? a. “Your prescriber hopes that at least one of these drugs will work to fight the tuberculosis.” b. “Taking multiple drugs reduces the chance that the tuberculosis will become drug Resistant c. “Using more than one drug can help to reduce side effects.” d. “Using multiple drugs enhances the effect of each drug.” ANS: B The use of multiple medications reduces the possibility that the organism will become drug resistant. The other options are incorrect. A patient who has started drug therapy for tuberculosis wants to know how long he will be on the medications. Which response by the nurse is correct? a. “Drug therapy will last until the symptoms have stopped.” b. “Drug therapy will continue until the tuberculosis develops resistance.” c. “You should expect to take these drugs for as long as 24 months.” d. “You will be on this drug therapy for the rest of your life.” ANS: C Drug therapy commonly lasts for 24 months if consistent drug therapy has been maintained. The other options are incorrect.
A patient who has been taking isoniazid (INH) has a new prescription for pyridoxine. She is wondering why she needs this medication. The nurse explains that pyridoxine is often given concurrently with the isoniazid to prevent which condition? a. Hair loss b. Renal failure c. Peripheral neuropathy d. Heart failure ANS: C Pyridoxine (vitamin B6) may be beneficial for isoniazid-induced peripheral neuropathy. The other options are incorrect. Lispro (Humalog) Onset? Nursing considerations? Teaching for hypoglycemia? Teaching for Self-injections? How to draw up multiple insulins? Pregnancy considerations? The nurse is administering insulin lispro (Humalog) and will keep in mind that this insulin will start to have an effect within which time frame? a. 15 minutes b. 1 to 2 hours c. 80 minutes d. 3 to 5 hours ANS: A The onset of action for insulin lispro is 15 minutes. The peak plasma concentration is 1 to 2 hours; the elimination half-life is 80 minutes; and the duration of action is 3 to 5 hours.
The nurse is teaching a group of patients about self-administration of insulin. What content is important to include? a. Patients need to use the injection site that is the most accessible. b. If two different insulins are ordered, they need to be given in separate injections. c. When mixing insulins, the cloudy (such as NPH) insulin is drawn up into the syringe first. d. When mixing insulins, the clear (such as regular) insulin is drawn up into the syringe first. ANS: D If mixing insulins in one syringe, the clear (regular) insulin is always drawn up into the syringe first. Patients always need to rotate injection sites. Mixing of insulins may be ordered. The nurse is reviewing instructions for a patient with type 2 diabetes who also takes insulin injections as part of the therapy. The nurse asks the patient, “What should you do if your fasting blood glucose is 47 mg/dL?” Which response by the patient reflects a correct understanding of insulin therapy? a. “I will call my doctor right away.” b. “I will give myself the regular insulin.” c. “I will take an oral form of glucose.” d. “I will rest until the symptoms pass.” ANS: C Hypoglycemia can be reversed if the patient eats glucose tablets or gel, corn syrup, or honey, or drinks fruit juice or a nondiet soft drink or other quick sources of glucose, which must always be kept at hand. She should not wait for instructions from her physician, nor delay taking the glucose by resting. The regular insulin would only lower her blood glucose levels more.
When teaching about hypoglycemia, the nurse will make sure that the patient is aware of the early signs of hypoglycemia, including: a. hypothermia and seizures. b. nausea and diarrhea. c. confusion and sweating. d. fruity, acetone odor to the breath. ANS: C Early symptoms of hypoglycemia include the central nervous system manifestations of confusion, irritability, tremor, and sweating. Hypothermia and seizures are later symptoms of hypoglycemia. The other options are incorrect. Which action is most appropriate regarding the nurse’s administration of a rapid-acting insulin to a hospitalized patient? a. Give it within 15 minutes of mealtime. b. Give it after the meal has been completed. c. Administer it once daily at the time of the midday meal. d. Administer it with a snack before bedtime. ANS: A Rapid-acting insulins, such as insulin lispro and insulin aspart, are able to mimic closely the body’s natural rapid insulin output after eating a meal; for this reason, both insulins are usually administered within 15 minutes of the patient’s mealtime. The other options are incorrect. The nurse is teaching a review class to nurses about diabetes mellitus. Which statement by the nurse is correct? a. “Patients with type 2 diabetes will never need insulin.” b. “Oral anti diabetic drugs are safe for use during pregnancy.” c. “Pediatric patients cannot take insulin.” d. “Insulin therapy is possible during pregnancy if managed carefully.” ANS: D Oral medications are generally not recommended for pregnant patients because of a lack of firm safety data. For this reason, insulin therapy is the only currently recommended drug therapy for
pregnant women with diabetes. Insulin is given to pediatric patients, with extreme care. Patients with type 2 diabetes may require insulin in certain situations or as their disease progresses. Methotrexate Medication interactions, contraindications? A patient is receiving high doses of methotrexate and is experiencing severe bone marrow suppression. The nurse expects which intervention to be ordered with this drug to reduce this problem? a. A transfusion of whole blood b. Leucovorin rescue c. Therapy with filgrastim (Neupogen) d. Administration of allopurinol (Zyloprim) ANS: B High-dose methotrexate is associated with bone marrow suppression, and it is always given in conjunction with the rescue drug leucovorin, which is an antidote for folic acid antagonists. Basically, leucovorin rescues the healthy cells from methotrexate. The other options are A patient who has been on methotrexate therapy is experiencing mild pain. The patient is asking for aspirin for the pain. The nurse recognizes that which of these is true in this situation? a. The aspirin will aggravate diarrhea. b. The aspirin will masks signs of infection. c. Aspirin can lead to methotrexate toxicity. d. The aspirin will cause no problems for the patient on methotrexate. ANS: C Methotrexate interacts with weak organic acids, such as aspirin, and can lead to toxicity by displacing the methotrexate from protein-binding sites.
