NR293 Exam 2 Practice Questions

Which patient-teaching instructions are appropriate for a patient taking an antidysrhythmic drug? (Select all that apply.) a. "Do not chew or crush extended-release forms of medication." b. "Take the medication with food if gastrointestinal distress occurs." c. "If a dose is missed, the missed dose should be taken along with the next dose that is due to be taken." d. "Take the medications with an antacid if gastrointestinal distress occurs." e. "Limit or avoid the use of caffeine." f. "The presence of a capsule in the stool should be reported to the physician immediately."

A, B, E a. "Do not chew or crush extended-release forms of medication." b. "Take the medication with food if gastrointestinal distress occurs." e. "Limit or avoid the use of caffeine."

The nurse is providing patient education for a patient taking an oral contraceptive. Which drugs may cause interactions with oral contraceptives? (Select all that apply.) a. Cephalexin (Keflex) b. Guaifenesin (Robitussin) c. Warfarin (Coumadin) d. Ibuprofen (Motrin) e. Theophylline (Uniphyl)

A, C, E a. Cephalexin (Keflex) c. Warfarin (Coumadin) e. Theophylline (Uniphyl)

The nurse is providing education about the use of sublingual nitroglycerin tablets. She asks the patient, "What would you do if you experienced chest pain while mowing your yard? You have your bottle of sublingual nitroglycerin with you." Which actions by the patient are appropriate in this situation? (Select all that apply.) a. Stop the activity, and lie down or sit down. b. Call 911 immediately. c. Call 911 if the pain is not relieved after taking one sublingual tablet. d. Call 911 if the pain is not relieved after taking three sublingual tablets in 15 minutes. e. Place a tablet under the tongue. f. Place a tablet in the space between the gum and cheek. g. Take another sublingual tablet if chest pain is not relieved after 5 minutes, up to three total.

A, C, E, G a. Stop the activity, and lie down or sit down. c. Call 911 if the pain is not relieved after taking one sublingual tablet. e. Place a tablet under the tongue. g. Take another sublingual tablet if chest pain is not relieved after 5 minutes, up to three total. With sublingual forms, the medication is taken at the first sign of chest pain, not delayed until the pain is severe. The patient needs to sit down or lie down and take one sublingual tablet. According to current guidelines, if the chest pain or discomfort is not relieved in 5 minutes, after 1 dose, the patient (or family member) must call 911 immediately. The patient can take one more tablet while awaiting emergency care and may take a third tablet 5 minutes later, but no more than a total of three tablets. These guidelines reflect the fact that angina pain that does not respond to nitroglycerin may indicate a myocardial infarction. The sublingual dose is placed under the tongue, and the patient needs to avoid swallowing until the tablet has dissolved. Placing a tablet between the gum and cheek is the buccal route.

When teaching a patient about antihypertensive drug therapy, which statements by the nurse are correct? (Select all that apply.) a. "You need to have your blood pressure checked once a week and keep track of the readings." b. "If you notice that the symptoms have gone away, you should be able to stop taking the drug." c. "An exercise program may be helpful in treating hypertension, but let's check with your doctor first." d. "If you experience severe side effects, stop the medicine and let us know at your next office visit." e. "Most over-the-counter decongestants are compatible with antihypertensive drugs." f. "Please continue taking the medication, even if you are feeling better."

A, C, F a. "You need to have your blood pressure checked once a week and keep track of the readings." c. "An exercise program may be helpful in treating hypertension, but let's check with your doctor first." f. "Please continue taking the medication, even if you are feeling better." Keeping a record of weekly blood pressure checks helps to monitor the effectiveness of the therapy. Remind the patient not to stop taking the medication just because he or she is feeling better. Abruptly stopping the medication may lead to rebound hypertension. Therapy is often lifelong, even though symptoms may improve. Many over-the-counter drugs, especially decongestants, have serious interactions with antihypertensive drugs. The patient needs to consult his or her prescriber before taking any other medication.

Take the iron tablets on an empty stomach 1 hour before meals. c. Take the iron tablets with an antacid to prevent heartburn. d. Drink 8 ounces of milk with each iron dose. e. Taking iron supplements with orange juice enhances iron absorption. f. Stools may become loose and light in color. g. Stools may become black and tarry. h. Tablets may be crushed to enhance iron absorption.

A, E, G a. Take the iron tablets with meals. e. Taking iron supplements with orange juice enhances iron absorption. g. Stools may become black and tarry. h. Tablets may be crushed to enhance iron absorption.

Which drug classes are considered first-line treatment for heart failure? (Select all that apply.) a. Angiotensin-converting enzyme (ACE) inhibitors b. Angiotensin II receptor blockers (ARBs) c. Digoxin (cardiac glycoside) d. Beta blockers e. Nesiritide (Natrecor), the B-type natriuretic peptide

ANS: A, B, D ACE inhibitors, ARBs, and beta blockers are now considered the first-line treatments for heart failure. Digoxin is used when the first-line treatments are not successful; nesiritide is considered a last-resort treatment.

Antilipemic drug therapy is prescribed for a patient, and the nurse is providing instructions to the patient about the medication. Which instructions will the nurse include? (Select all that apply.) a. Limit fluid intake to prevent fluid overload. b. Eat extra servings of raw vegetables and fruit. c. Report abnormal or unusual bleeding or yellow discoloration of the skin. d. Report the occurrence of muscle pain immediately. e. Drug interactions are rare with antilipemics. f. Take the drug 1 hour before or 2 hours after meals to maximize absorption.

B, C, D b. Eat extra servings of raw vegetables and fruit. c. Report abnormal or unusual bleeding or yellow discoloration of the skin. d. Report the occurrence of muscle pain immediately.

The nurse is reviewing the uses of oral laxatives. Which conditions are general contraindications to or cautions about the use of oral laxatives? (Select all that apply.) a.

B, C, D, F b. Undiagnosed abdominal pain c. Nausea and vomiting d. Fecal impaction f. Acute surgical abdomen Cautious use of laxatives is recommended in the presence of these: acute surgical abdomen; appendicitis symptoms, such as abdominal pain, nausea, and vomiting; intestinal obstruction; and undiagnosed abdominal pain. Oral laxatives must not be used with fecal impaction; mineral oil enemas are indicated for fecal impaction. The other options are indications for laxative use.

The nurse is providing patient teaching about antacids. Which statements about antacids are accurate? (Select all that apply.) a. Antacids reduce the production of acid in the stomach. b. Antacids neutralize acid in the stomach. c. Rebound hyperacidity may occur with calcium-based antacids. d. Aluminum-based antacids cause diarrhea. e. Magnesium-based antacids cause diarrhea.

B, C, E b. Antacids neutralize acid in the stomach. c. Rebound hyperacidity may occur with calcium-based antacids. e. Magnesium-based antacids cause diarrhea.

When a patient is experiencing digoxin toxicity, which clinical situation would necessitate the use of digoxin immune Fab (Digifab)? (Select all that apply.) a. The patient reports seeing colorful halos around lights. b. The patient's serum potassium level is above 5 mEq/L. c. The patient is experiencing nausea and anorexia. d. The patient is experiencing severe sinus bradycardia that does not respond to cardiac pacing. e. The patient has received an overdose of greater than 10 mg of digoxin. f. The patient reports fatigue and headaches.

B, D, E b. The patient's serum potassium level is above 5 mEq/L. d. The patient is experiencing severe sinus bradycardia that does not respond to cardiac pacing. e. The patient has received an overdose of greater than 10 mg of digoxin. Clinical situations that would require the use of digoxin immune Fab in a patient with digoxin toxicity include serum potassium level above 5 mEq/L, severe sinus bradycardia that does not respond to cardiac pacing, or an overdose of more than 10 mg of digoxin. Seeing colorful halos around lights and experiencing nausea, anorexia, fatigue, and headaches are potential adverse effects of digoxin therapy but are not necessarily reasons for digoxin immune Fab treatment.

The nurse is monitoring for adverse effects in a patient who is receiving an amiodarone (Cordarone) infusion. Which are adverse effects for amiodarone? (Select all that apply.) a. Tachycardia b. Constipation c. Chest pain d. QT prolongation e. Headache f. Hypotension g. Blue-gray coloring of the skin on the face, arms, and neck

B, D, F, G b. Constipation d. QT prolongation f. Hypotension g. Blue-gray coloring of the skin on the face, arms, and neck

A patient is on a chemotherapy regimen in an outpatient clinic and is receiving a chemotherapy drug that is known to be highly emetogenic. The nurse will implement which interventions regarding the pharmacologic management of nausea and vomiting? (Select all that apply.) a. Giving antinausea drugs at the beginning of the chemotherapy infusion b. Administering antinausea drugs 30 to 60 minutes before chemotherapy is started c. For best therapeutic effects, medicating for nausea once the symptoms begin d. Observing carefully for the adverse effects of restlessness and anxiety e. Instructing the patient that the antinausea drugs may cause extreme drowsiness f. Instructing the patient to rise slowly from a sitting or lying position because of possible orthostatic hypotension

B, E, F b. Administering antinausea drugs 30 to 60 minutes before chemotherapy is started e. Instructing the patient that the antinausea drugs may cause extreme drowsiness f. Instructing the patient to rise slowly from a sitting or lying position because of possible orthostatic hypotension (Antiemetics should be given before any chemotherapy drug is administered, often 30 to 60 minutes before treatment, but not immediately before chemotherapy is administered. Do not wait until the nausea begins. Most antiemetics cause drowsiness, not restlessness and anxiety. Orthostatic hypotension is a possible adverse effect that may lead to injury.)

When assessing a patient who is receiving a loop diuretic, the nurse looks for the manifestations of potassium deficiency, which would include what symptoms? (Select all that apply.) a. Dyspnea b. Constipation c. Tinnitus d. Muscle weakness e. Anorexia f. Lethargy

D, E, F d. Muscle weakness e. Anorexia f. Lethargy

A 74-year-old professional golfer has chest pain that occurs toward the end of his golfing games. He says the pain usually goes away after one or two sublingual nitroglycerin tablets and rest. What type of angina is he experiencing? a. Classic b. Variant c. Unstable d. Prinzmetal's

a. Classic Classic, or chronic stable, angina is triggered by either exertion or stress and usually subsides within 15 minutes with either rest or drug therapy.

When applying transdermal nitroglycerin patches, which instruction by the nurse is correct? a. "Rotate application sites with each dose." b. "Use only the chest area for application sites." c. "Temporarily remove the patch if you go swimming." d. "Apply the patch to the same site each time."

a. "Rotate application sites with each dose." Application sites for transdermal nitroglycerin patches need to be rotated. Apply the transdermal patch to any nonhairy area of the body; the old patch should first be removed. The patch may be worn while swimming, but if it does come off, it should be replaced after the old site is cleansed.

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

a. 0.5 mg One vial of digoxin immune Fab binds 0.5 mg of digoxin.

A patient's blood pressure elevates to 270/150 mm Hg, and a hypertensive emergency is obvious. He is transferred to the intensive care unit and started on a sodium nitroprusside (Nipride) drip to be titrated per his response. With this medication, the nurse knows that the maximum dose of this drug should be infused for how long? a. 10 minutes b. 30 minutes c. 1 hour d. 24 hours

a. 10 minutes Sodium nitroprusside is a potent vasodilator and may lead to extreme decreases in the patient's blood pressure. For this reason, it is never infused at the maximum dose for more than 10 minutes. If this drug does not control a patient's blood pressure after 10 minutes, it will most likely be ordered to be discontinued. The other times listed 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

a. Assess the patient for symptoms of digoxin toxicity. 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 arrives in the emergency department with severe chest pain. The patient reports that the pain has been occurring off and on for a week now. Which assessment finding would indicate the need for cautious use of nitrates and nitrites? a. Blood pressure of 88/62 mm Hg b. Apical pulse rate of 110 beats/min c. History of renal disease d. History of a myocardial infarction 2 years ago

a. Blood pressure of 88/62 mm Hg Hypotension is a possible contraindication to the use of nitrates because the medications may cause the blood pressure to decrease

The nurse is preparing for a community education program on hypertension. Which of these parameters determine the regulation of arterial blood pressure? a. Cardiac output and systemic vascular resistance b. Heart rate and peripheral resistance c. Blood volume and renal blood flow d. Myocardial contractility and arteriolar constriction

a. Cardiac output and systemic vascular resistance Blood pressure is determined by the product of cardiac output and systemic vascular resistance. The other options are incorrect.

An older adult patient had gastric surgery due to a gastrointestinal bleed 3 days ago, and he has been stable since the surgery. This evening, his daughter tells the nurse, "He seems to be more confused this afternoon. He's never been like this. What could be the problem?" The nurse reviews the patient's medication record and suspects that which drug could be the cause of the patient's confusion? a. Cimetidine (Tagamet) b. Pantoprazole (Protonix) c. Clarithromycin (Biaxin) d. Sucralfate (Carafate)

a. Cimetidine (Tagamet) Sometimes H2 receptor antagonists such as cimetidine may cause adverse effects related to the central nervous system in the older adult, including confusion and disorientation. The nurse needs to be alert for mental status changes when giving these drugs, especially if the changes are new to the patient.

A patient is being discharged on anticoagulant therapy. The nurse will include in the patient education conversation that it is important to avoid herbal products that contain which substance? a. Valerian b. Ginkgo c. Soy d. Saw palmetto

b. Ginkgo Capsicum pepper, feverfew, garlic, ginger, ginkgo, St. John's wort, and ginseng are some herbals that have potential interactions with anticoagulants, especially with warfarin.

The nurse is discussing the use of adsorbents such as bismuth subsalicylate (Pepto-Bismol) with a patient who has diarrhea. The nurse will warn the patient about which possible adverse effects? a. Dark stools and blue gums b. Urinary hesitancy c. Drowsiness and dizziness d. Blurred vision and headache

a. Dark stools and blue gums Dark stools and blue gums are two of the possible adverse effects of bismuth subsalicylate (see Table 51-2). The other adverse effects listed may occur with the use of other antidiarrheal drugs.

When monitoring a patient who is taking hydrochlorothiazide (HydroDIURIL), the nurse notes that which drug is most likely to cause a severe interaction with the diuretic? a. Digitalis b. Penicillin c. Potassium supplements d. Aspirin

a. Digitalis There is an increased risk for digitalis toxicity in the presence of hypokalemia, which may develop with hydrochlorothiazide therapy. Potassium supplements are often prescribed with hydrochlorothiazide therapy to prevent hypokalemia. The other options do not have interactions with hydrochlorothiazide.

A patient is receiving lactulose (Enulose) three times a day. The nurse knows that the patient is not constipated and is receiving this drug for which reason? a. High ammonia levels due to liver failure b. Prevention of constipation c. Chronic renal failure d. Chronic diarrhea

a. High ammonia levels due to liver failure Lactulose (Enulose) produces a laxative effect but also works to reduce blood ammonia levels by converting ammonia to ammonium. Ammonium is a water-soluble cation that is trapped in the intestines and cannot be reabsorbed into the systemic circulation. This effect has proved helpful in reducing elevated serum ammonia levels in patients with severe liver disease.

A patient will be taking bismuth subsalicylate (Pepto-Bismol) to control diarrhea. When reviewing the patient's other ordered medications, the nurse recognizes that which medication or medication class will interact significantly with the Pepto-Bismol? a. Hypoglycemic drugs b. Antibiotics c. Acetaminophen (Tylenol) d. Antidepressants

a. Hypoglycemic drugs Taking hypoglycemic drugs with an adsorbent such as bismuth subsalicylate may result in decreased absorption of the hypoglycemic drugs.

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

a. Impotence 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.

A patient is being discharged to home on a single daily dose of a diuretic. The nurse instructs the patient to take the dose at which time so it will be least disruptive to the patient's daily routine? a. In the morning b. At noon c. With supper d. At bedtime

a. In the morning It is better to take the diuretic medication early in the morning to prevent urination during the night. Taking the diuretic at the other times may cause nighttime urination and disrupt sleep.

Mannitol (Osmitrol) has been ordered for a patient with acute renal failure. The nurse will administer this drug using which procedure? a. Intravenously, through a filter b. By rapid intravenous bolus c. By mouth in a single morning dose d. Through a gravity intravenous drip with standard tubing

a. Intravenously, through a filter Mannitol is administered via intravenous infusion through a filter because of possible crystallization. It is not available in oral form.

A patient who has severe nausea and vomiting following a case of food poisoning comes to the urgent care center. When reviewing his medication history, the nurse notes that he has an allergy to procaine. The nurse would question an order for which antiemetic drug if ordered for this patient? a. Metoclopramide (Reglan) b. Promethazine (Phenergan) c. Phosphorated carbohydrate solution (Emetrol) d. Palonosetron (Aloxi)

a. Metoclopramide (Reglan) The use of metoclopramide (Reglan) is contraindicated in patients with a hypersensitivity to procaine or procainamide. There are no known interactions with the drugs listed in the other options.

The nurse is reviewing the medication list of a patient who will be starting androgen therapy. Which drug classes, if taken with androgens, may have an interaction with them? a. Oral anticoagulants b. Nitrates c. Beta blockers d. Proton pump inhibitors

a. Oral anticoagulants Androgens, when used with oral anticoagulants, can significantly increase or decrease anticoagulant activity.

A patient in the intensive care unit has a nasogastric tube and is also receiving a proton pump inhibitor (PPI). The nurse recognizes that the purpose of the PPI is which effect? a. Prevent stress ulcers b. Reduce bacteria levels in the stomach c. Reduce gastric gas formation (flatulence) d. Promote gastric motility

a. Prevent stress ulcers Stress-related mucosal damage is an important issue for critically ill patients. Stress ulcer prophylaxis (or therapy to prevent severe gastrointestinal [GI] damage) is undertaken in almost every critically ill patient in an intensive care unit and for many patients on general medical surgical units. Procedures performed commonly in critically ill patients, such as passing nasogastric tubes, placing patients on ventilators, and others, predispose patients to bleeding of the GI tract. Guidelines suggest that all such patients receive either a histamine receptor-blocking drug or a proton pump inhibitor.

A patient is receiving a tube feeding through a gastrostomy. The nurse expects that which type of drug will be used to promote gastric emptying for this patient? a. Prokinetic drugs, such as metoclopramide (Reglan) b. Serotonin blockers, such as ondansetron (Zofran) c. Anticholinergic drugs, such as scopolamine (Transderm-Scop) d. Neuroleptic drugs, such as chlorpromazine (Thorazine)

a. Prokinetic drugs, such as metoclopramide (Reglan) Prokinetic drugs promote the movement of substances through the gastrointestinal tract and increase gastrointestinal motility.

A patient is asking advice about which over-the-counter antacid is considered the most safe to use for heartburn. The nurse explains that the reason that calcium antacids are not used as frequently as other antacids is for which of these reasons? a. Their use may result in kidney stones. b. They cause decreased gastric acid production. c. They cause severe diarrhea. d. Their use may result in fluid retention and edema.

a. Their use may result in kidney stones. Calcium antacids are not used as frequently as other antacids because their use may lead to the development of kidney stones; they also cause increased gastric acid production.

The nurse recognizes that the risk of osteoporosis is higher in an individual with which risk factor? a. White or Asian race b. African-American race c. History of participation in active sports d. Obesity

a. White or Asian race Risk factors for postmenopausal osteoporosis include white or Asian descent, slender body build, early estrogen deficiency, smoking, alcohol consumption, low-calcium diet, sedentary lifestyle, and family history of osteoporosis.

A mother calls the pediatrician's office to report that her 18-month-old child has eaten half of a bottle of baby aspirin. She says, "I have a bottle of syrup of ipecac. Should I give it to him? He seems fine right now. What do I do?" What is the nurse's best response? a. "Go ahead and give him the ipecac, and then call 911." b. "Don't give him the ipecac. Call the Poison Control number immediately for instructions." c. "Please come to the office right away so that we can check him." d. "Go ahead and take him to the emergency room right now."

b. "Don't give him the ipecac. Call the Poison Control number immediately for instructions." The American Academy of Pediatrics no longer recommends the use of syrup of ipecac for home treatment for poisoning. Instructions state that if the poison has been ingested, first call the national poison control hotline at 800-222-1222. In all cases of poisoning, if the victim is conscious and alert, call the local poison control center. If the victim has collapsed or stopped breathing, call 911 for emergency transport to a hospital.

The nurse is providing patient teaching about the oral bisphosphonate alendronate (Fosamax). Which statement by the patient indicates a good understanding of when this drug should be taken? a. "I will take it in the evening just before bedtime." b. "I will take it in the morning with an 8-ounce glass of water." c. "I will take it with the first bite of the morning meal." d. "I will take it between meals on an empty stomach."

b. "I will take it in the morning with an 8-ounce glass of water." Bisphosphonates must be taken in the morning, with 6 to 8 ounces of plain water, to prevent esophageal erosion. In addition, the patient must sit upright for 30 minutes after taking them.

A patient who has recently started therapy on a statin drug asks the nurse how long it will take until he sees an effect on his serum cholesterol. Which statement would be the nurse's best response? a. "Blood levels return to normal within a week of beginning therapy." b. "It takes 6 to 8 weeks to see a change in cholesterol levels." c. "It takes at least 6 months to see a change in cholesterol levels." d. "You will need to take this medication for almost a year to see significant results."

b. "It takes 6 to 8 weeks to see a change in cholesterol levels." The maximum extent to which lipid levels are lowered may not occur until 6 to 8 weeks after the start of therapy. The other responses are incorrect.

The nurse is administering intravenous iron dextran for the first time to a patient with anemia. After giving a test dose, how long will the nurse wait before administering the remaining portion of the dose? a. 30 minutes b. 1 hour c. 6 hours d. 24 hours

b. 1 hour Although anaphylactic reactions usually occur within a few moments after the test dose, it is recommended that a period of at least 1 hour elapse before the remaining portion of the initial dose is given.

The nurse is preparing to transfuse a patient with a unit of packed red blood cells (PRBCs). Which patient would be best treated with this transfusion? a. A patient with a coagulation disorder b. A patient with severe anemia c. A patient who has lost a massive amount of blood after an accident d. A patient who has a clotting-factor deficiency

b. A patient with severe anemia PRBCs are given to increase the oxygen-carrying capacity in patients with anemia, in patients with substantial hemoglobin deficits, and in patients who have lost up to 25% of their total blood volume. Patients with coagulation disorder or clotting-factor deficiency would receive fresh frozen plasma; a patient who has lost a massive amount of blood would receive whole blood.

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

b. Activated partial thromboplastin time (aPTT) 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 who has been taking antihypertensive drugs for a few months complains of having a persistent dry cough. The nurse knows that this cough is an adverse effect of which class of antihypertensive drugs? a. Beta blockers b. Angiotensin-converting enzyme (ACE) inhibitors c. Angiotensin II receptor blockers (ARBs) d. Calcium channel blockers

b. Angiotensin-converting enzyme (ACE) inhibitors ACE inhibitors cause a characteristic dry, nonproductive cough that reverses when therapy is stopped. The other drug classes do not cause this cough.

A patient wants to prevent problems with constipation and asks the nurse for advice about which type of laxative is safe to use for this purpose. Which class of laxative is considered safe to use on a long-term basis? a. Emollient laxatives b. Bulk-forming laxatives c. Hyperosmotic laxatives d. Stimulant laxatives

b. Bulk-forming laxatives Bulk-forming laxatives are the only laxatives recommended for long-term use. Stimulant laxatives are the most likely of all the laxative classes to cause dependence.

A patient is receiving an aluminum-containing antacid. The nurse will inform the patient to watch for which possible adverse effect? a. Diarrhea b. Constipation c. Nausea d. Abdominal cramping

b. Constipation Aluminum-based antacids have a constipating effect as well as an acid-neutralizing capacity.

Which nursing diagnosis is appropriate for a patient receiving antidysrhythmics? a. Risk for infection b. Deficient knowledge c. Deficient fluid volume d. Urinary retention

b. Deficient knowledge Deficient knowledge related to lack of experience with medication therapy is a potential nursing diagnosis for a patient receiving antidysrhythmics.

A patient on chemotherapy is using ondansetron (Zofran) for treatment of nausea. The nurse will instruct the patient to watch for which adverse effect of this drug? a. Dizziness b. Diarrhea c. Dry mouth d. Blurred vision

b. Diarrhea Diarrhea is an adverse effect of the serotonin blockers. The other adverse effects listed may occur with anticholinergic drugs.

When teaching a patient who is beginning antilipemic therapy about possible drug-food interactions, the nurse will discuss which food? a. Oatmeal b. Grapefruit juice c. Licorice d. Dairy products

b. Grapefruit juice Taking HMG-CoA reductase inhibitors with grapefruit juice may cause complications. Components in grapefruit juice inactivate CYP3A4 in both the liver and intestines. This enzyme plays a key role in statin metabolism. The presence of grapefruit juice in the body may therefore result in sustained levels of unmetabolized statin drug, which increases the risk for major drug toxicity, possibly leading to rhabdomyolysis.

The nurse will monitor for myopathy (muscle pain) when a patient is taking which class of antilipemic drugs? a. Niacin b. HMG-CoA reductase inhibitors c. Fibric acid derivatives d. Bile acid sequestrants

b. HMG-CoA reductase inhibitors Myopathy (muscle pain) is a clinically important adverse effect that may occur with HMG-CoA reductase inhibitors. It may progress to a serious condition known as rhabdomyolysis. Patients receiving statin therapy need to be advised to report any unexplained muscular pain or discomfort to their health care providers immediately. The other drugs and drug classes do not cause muscle pain or myopathy.

An oral iron supplement is prescribed for a patient. The nurse would question this order if the patient's medical history includes which condition? a. Decreased hemoglobin b. Hemolytic anemia c. Weakness d. Concurrent therapy with erythropoietics

b. Hemolytic anemia Hemolytic anemia is a contraindication to the use of iron supplements. Decreased hemoglobin and weakness are related to iron-deficiency anemia. Iron supplements are given with erythropoietic drugs to aid in the production of red blood cells.

A patient has been taking iron supplements for anemia for 2 months. During a follow-up assessment, the nurse will observe for which therapeutic response? a. Decreased weight b. Increased activity tolerance c. Decreased palpitations d. Increased appetite

b. Increased activity tolerance Absence of fatigue, increased activity tolerance and well-being, and improved nutrition status are therapeutic responses to iron supplementation.

The nurse is administering liquid oral iron supplements. Which intervention is appropriate when administering this medication? a. Have the patient take the liquid iron with milk. b. Instruct the patient to take the medication through a plastic straw. c. Have the patient sip the medication slowly. d. Have the patient drink the medication, undiluted, from the unit-dose cup.

b. Instruct the patient to take the medication through a plastic straw. Liquid oral forms of iron need to be taken through a plastic straw to avoid discoloration of tooth enamel. Milk may decrease absorption.

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.

b. It is within the therapeutic range. The normal therapeutic drug level of digoxin is between 0.5 and 2 ng/mL. The other options are incorrect

A patient in the neurologic intensive care unit is being treated for cerebral edema. Which class of diuretic is used to reduce intracranial pressure? a. Loop diuretics b. Osmotic diuretics c. Thiazide diuretics d . Vasodilators

b. Osmotic diuretics Mannitol, an osmotic diuretic, is commonly used to reduce intracranial pressure and cerebral edema resulting from head trauma.

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 4

b. Prolonging action potential duration 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.

When reviewing the health history of a patient who will be receiving antacids, the nurse recalls that antacids containing magnesium need to be used cautiously in patients with which condition? a. Peptic ulcer disease b. Renal failure c. Hypertension d. Heart failure

b. Renal failure Both calcium- and magnesium-based antacids are more likely to accumulate to toxic levels in patients with renal disease and are commonly avoided in this patient group.

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

b. Renal protective effects 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.

A patient is taking chemotherapy with a drug that has a high potential for causing nausea and vomiting. The nurse is preparing to administer an antiemetic drug. Which class of antiemetic drugs is most commonly used to prevent nausea and vomiting for patients receiving chemotherapy? a. Prokinetic drugs, such as metoclopramide (Reglan) b. Serotonin blockers, such as ondansetron (Zofran) c. Anticholinergic drugs, such as scopolamine d. Neuroleptic drugs, such as promethazine (Phenergan)

A patient who is taking the bisphosphonate alendronate (Fosamax) has been instructed to lie flat in bed for 2 days after having ophthalmic surgery. Which intervention is appropriate at this time? a. She will continue to take the alendronate with water. b. She cannot take the alendronate until she can sit up for 30 minutes. c. She can take the medication with breakfast. d. She will stop taking the medication 72 hours before her surgery. The nurse must emphasize that the patient should remain upright in either a standing or sitting position for approximately 30 minutes after taking a bisphosphonate so as to help prevent esophageal erosion or irritation. Because this patient will be required to lie flat in bed for 2 days after the surgery, the prescriber will need to be notified that the patient cannot take the medication during this time.

b. She cannot take the alendronate until she can sit up for 30 minutes. The nurse must emphasize that the patient should remain upright in either a standing or sitting position for approximately 30 minutes after taking a bisphosphonate so as to help prevent esophageal erosion or irritation. Because this patient will be required to lie flat in bed for 2 days after the surgery, the prescriber will need to be notified that the patient cannot take the medication during this time.

A 73-year-old male patient is in the clinic for a yearly physical and is asking for a prescription for sildenafil (Viagra). He has listed on his health history that he is taking a nitrate for angina. The nurse is aware that which problem may occur if sildenafil is taken with a nitrate? a. Significant increase in pulse rate b. Significant decrease in blood pressure c. Increased risk of bleeding d. Reduced effectiveness of the sildenafil

b. Significant decrease in blood pressure In patients with pre-existing cardiovascular disease, especially those on nitrates, erectile dysfunction drugs such as sildenafil lower blood pressure substantially, potentially leading to more serious adverse events.

The nurse is administering oxytocin (Pitocin). Which situation is an indication for the use of oxytocin? a. Decreased fetal heart rate and movements b. Stimulation of contractions during labor c. Cervical ripening near term in pregnant patients d. To reverse premature onset of labor

b. Stimulation of contractions during labor Oxytocin is used to induce labor at or near full-term gestation and to enhance labor when uterine contractions are weak and ineffective.

A patient who has been anticoagulated with warfarin (Coumadin) has been admitted for gastrointestinal bleeding. The history and physical examination indicates that the patient may have taken too much warfarin. The nurse anticipates that the patient will receive which antidote? a. Vitamin E b. Vitamin K c. Protamine sulfate d. Potassium chloride

b. Vitamin K Vitamin K is given to reverse the anticoagulation effects of warfarin toxicity. Protamine sulfate is the antidote for heparin overdose

During a follow-up visit, a patient who has been on estrogen therapy admits that she has continued to smoke cigarettes. The nurse will remind the patient that smoking while on estrogen may lead to increased: a. incidence of nausea. b. risk for thrombosis. c. levels of triglycerides. d. tendency to bleed during menstruation.

b. risk for thrombosis. Smoking should be avoided during estrogen therapy because it adds to the risk for thrombosis formation. The other options are incorrect.

A patient has had recent mechanical heart valve surgery and is receiving anticoagulant therapy. While monitoring the patient's laboratory work, the nurse interprets that the patient's international normalized ratio (INR) level of 3 indicates that: a. the patient is not receiving enough warfarin to have a therapeutic effect. b. the patient's warfarin dose is at therapeutic levels. c. the patient's intravenous heparin dose is dangerously high. d. the patient's intravenous heparin dose is at therapeutic levels.

b. the patient's warfarin dose is at therapeutic levels. A normal INR (without warfarin) is 1.0. A therapeutic INR for patients who have had mechanical heart valve surgery ranges from 2.5 to 3.5, with a middle value of 3.

The nurse is providing teaching for a patient who is to receive estrogen replacement therapy. Which statement is correct to include in the teaching session? a. "If you miss a dose, double-up on the next dose." b. "There's no need to be concerned about breast lumps or bumps that occur." c. "Be sure to report any weight gain of 5 pounds or more per week." d. "Take the medication on an empty stomach to enhance absorption."

c. "Be sure to report any weight gain of 5 pounds or more per week." Patients taking oral estrogen therapy should report weight gain of 5 pounds or more per week to a physician. The other statements are not true for estrogen replacement therapy.

A patient with motion sickness is planning a cross-country car trip and has a new prescription for a scopolamine transdermal patch (Transderm-Scop). The nurse provides teaching for the use of this patch medication. The patient shows a correct understanding of the teaching with which statement? a. "I will change the patch every day." b. "I will change the patch every other day." c. "I will change the patch every 3 days." d. "I will remove the patch only if it stops working."

c. "I will change the patch every 3 days." Scopolamine patches are 72-hour doses and are changed every 3 days.

A patient is to receive testosterone therapy via a transdermal patch. He asks the nurse, "Why am I getting a patch? Can't I just take a pill?" Which response by the nurse is correct? a. "The patch reduces the incidence of side effects." b. "If you don't take the patch, you will have to have injections instead." c. "The patch allows for better absorption of the medication." d. "You will only have to change the patch weekly."

c. "The patch allows for better absorption of the medication." The transdermal form allows for better absorption of testosterone because of its high first-pass effect. Oral forms are poorly absorbed, and the transdermal form is preferable to an injection and is preferred for hormonal replacement therapy. The patch is changed daily.

A laxative has been ordered for a patient. The nurse checks the patient's medical history and would be concerned if which condition is present? a. High ammonia levels due to liver failure b. Diverticulosis c. Abdominal pain of unknown origin d. Chronic constipation

c. Abdominal pain of unknown origin All categories of laxatives share the same general contraindications and precautions, including avoidance in cases of drug allergy and the need for cautious use in the presence of these: acute surgical abdomen; appendicitis symptoms such as abdominal pain, nausea, and vomiting; fecal impaction (mineral oil enemas excepted); intestinal obstruction; and undiagnosed abdominal pain. The other options are possible indications for laxatives.

A patient is receiving oxytocin (Pitocin) to induce labor. During administration of this medication, the nurse will also implement which action? a. Giving magnesium sulfate along with the oxytocin b. Administering the medication in an intravenous (IV) bolus c. Administering the medication with an IV infusion pump d. Monitoring fetal heart rate and maternal vital signs every 6 hours

c. Administering the medication with an IV infusion pump Oxytocin is infused via an infusion pump, not via an IV bolus. Magnesium sulfate is not administered with oxytocin. Fetal heart rate and maternal vital signs should be monitored continuously.

The nurse will prepare to give which drug of choice for this dysrhythmia? a. Diltiazem (Cardizem) b. Verapamil (Calan) c. Amiodarone (Cordarone) d. Adenosine (Adenocard)

c. Amiodarone (Cordarone) Amiodarone (Cordarone) is the drug of choice for ventricular dysrhythmias according to the Advanced Cardiac Life Support guidelines. The other drugs are not used for acute ventricular dysrhythmias.

The nurse is preparing to administer adenosine (Adenocard) to a patient who is experiencing an acute episode of paroxysmal supraventricular tachycardia. When giving this medication, which is important to remember? a. The onset of action occurs in 5 minutes. b. The medication must be given as a slow intravenous (IV) push. c. Asystole may occur for a few seconds after administration. d. The medication has a long half-life, and therefore duration of action is very long.

c. Asystole may occur for a few seconds after administration. Adenosine has an extremely short half-life of less than 10 seconds; its onset occurs within 1 minute; and it must be given as a fast IV push injection. In addition, a very brief episode of asystole may occur after administration.

The nurse will teach a patient who is receiving oral iron supplements to watch for which expected adverse effects? a. Palpitations b. Drowsiness and dizziness c. Black, tarry stools d. Orange-red discoloration of the urine

Vasodilators alone b. ACE inhibitors alone c. Calcium channel blockers with thiazide diuretics d. Beta blockers with thiazide diuretics

c. Calcium channel blockers with thiazide diuretics According to the JNC-8 guidelines, calcium channel blockers and diuretics are recommended as first-line therapy for management of hypertension in African-American patients. The other drugs are not recommended as first-line drugs for this group.

A patient is receiving an infusion of fresh frozen plasma. Based on this order, the nurse interprets that this patient has which condition? a. Hypovolemic shock b. Anemia c. Coagulation disorder d. Previous transfusion reaction

c. Coagulation disorder Fresh frozen plasma is used as an adjunct to massive blood transfusion in the treatment of patients with underlying coagulation disorders. The other options are not indications for fresh frozen plasma.

At 0900, the nurse is about to give morning medications, and the patient has asked for a dose of antacid for severe heartburn. Which schedule for the antacid and medications is correct? a. Give both the antacid and medications at 0900. b. Give the antacid at 0900, and then the medications at 0930. c. Give the medications at 0900, and then the antacid at 1000. d. Give the medications at 0900, and then the antacid at 0915.

c. Give the medications at 0900, and then the antacid at 1000. Medications are not to be taken, unless prescribed, within 1 to 2 hours of taking an antacid because of the impact on the absorption of many medications in the stomach.

A patient has been diagnosed with angina and will be given a prescription for sublingual nitroglycerin tablets. When teaching the patient how to use sublingual nitroglycerin, the nurse will include which instruction? a. Take up to 5 doses at 15-minute intervals for an angina attack. b. If the tablet does not dissolve quickly, chew the tablet for maximal effect. c. If the chest pain is not relieved after one tablet, call 911 immediately. d. Wait 1 minute between doses of sublingual tablets, up to 3 doses.

c. If the chest pain is not relieved after one tablet, call 911 immediately. According to current guidelines, if the chest pain or discomfort is not relieved in 5 minutes, after 1 dose, the patient (or family member) must call 911 immediately. The patient may take one more tablet while awaiting emergency care and may take a third tablet 5 minutes later, but no more than a total of three tablets. The sublingual dose is placed under the tongue, and the patient needs to avoid swallowing until the tablet has dissolved.

When a patient is receiving diuretic therapy, which of these assessment measures would best reflect the patient's fluid volume status? a. Blood pressure and pulse b. Serum potassium and sodium levels c. Intake, output, and daily weight d. Measurements of abdominal girth and calf circumference

c. Intake, output, and daily weight Urinary intake and output and daily weights are the best reflections of a patient's fluid volume status.

While recovering from surgery, a 74-year-old woman started taking a stimulant laxative, senna (Senokot), to relieve constipation caused by the pain medications. Two weeks later, at her follow-up appointment, she tells the nurse that she likes how "regular" her bowel movements are now that she is taking the laxative. Which teaching principle is appropriate for this patient? a. She needs to be sure to take this medication with plenty of fluids. b. It is important to have a daily bowel movement to promote bowel health. c. Long-term use of laxatives often results in decreased bowel tone and may lead to dependency. d. She needs to switch to glycerin suppositories to continue having daily bowel movements.

c. Long-term use of laxatives often results in decreased bowel tone and may lead to dependency. Long-term use of laxatives may lead to dependency. Patients need to be taught that daily bowel movements are not necessary for bowel health

A patient is severely constipated and needs immediate relief. The nurse knows that which class of laxative will provide the most rapid results? a. Bulk-forming laxative, such as psyllium (Metamucil) b. Stool softener, such as docusate salts (Colace) c. Magnesium hydroxide (MOM) d. Magnesium oxide tablets

c. Magnesium hydroxide (MOM) Saline laxatives such as magnesium hydroxide (MOM) produce a watery stool, usually within 3 to 6 hours of ingestion. Bulk-forming laxatives such as psyllium do not produce a bowel movement rapidly. Stool softeners such as docusate salts do not cause patients to defecate; they simply soften the stool to ease its passage. Magnesium oxide tablets are used as magnesium supplements, not as laxatives.

A 75-year-old woman comes into the clinic with complaints of muscle twitching, nausea, and headache. She tells the nurse that she has been taking sodium bicarbonate five or six times a day for the past 3 weeks. The nurse will assess for which potential problem that may occur with overuse of sodium bicarbonate? a. Constipation b. Metabolic acidosis c. Metabolic alkalosis d. Excessive gastric mucus

c. Metabolic alkalosis Excessive use of sodium bicarbonate may lead to systemic alkalosis.

The nurse is reviewing the orders for a patient and notes a new order for an angiotensinconverting enzyme (ACE) inhibitor. The nurse checks the current medication orders, knowing that this drug class may have a serious interaction with what other drug class? a. Calcium channel blockers b. Diuretics c. Nonsteroidal anti-inflammatory drugs d. Nitrates

c. Nonsteroidal anti-inflammatory drugs Nonsteroidal anti-inflammatory drugs (NSAIDs) such as ibuprofen can reduce the antihypertensive effect of ACE inhibitors. In addition, the use of NSAIDs and ACE inhibitors may also predispose patients to the development of acute renal failure.

The nurse notes in the patient's medication orders that the patient will be starting anticoagulant therapy. What is the primary goal of anticoagulant therapy? a. Stabilizing an existing thrombus b. Dissolving an existing thrombus c. Preventing thrombus formation d. Dilating the vessel around a clot

c. Preventing thrombus formation Anticoagulants prevent thrombus formation but do not dissolve or stabilize an existing thrombus, nor do they dilate vessels around a clot.

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

c. Protamine sulfate 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.

When the nurse is administering topical nitroglycerin ointment, which technique is correct? a. Apply the ointment on the skin on the forearm. b. Apply the ointment only in the case of a mild angina episode. c. Remove the old ointment before new ointment is applied. d. Massage the ointment gently into the skin, and then cover the area with plastic wrap.

c. Remove the old ointment before new ointment is applied. The old ointment should be removed before a new dose is applied. The ointment should be applied to clean, dry, hairless skin of the upper arms or body, not below the elbows or below the knees. The ointment is not massaged or spread on the skin, and it is not indicated for the treatment of acute angina.

A nurse is giving instructions to a patient who will be receiving oral iron supplements. Which instructions will be included in the teaching plan? a. Take the iron tablets with milk or antacids. b. Crush the pills as needed to help with swallowing. c. Take the iron tablets with meals if gastrointestinal distress occurs. d. If black tarry stools occur, report it to the doctor immediately.

c. Take the iron tablets with meals if gastrointestinal distress occurs. Although taking iron tablets with food may decrease absorption, doing so helps to reduce gastrointestinal distress. Antacids and milk may cause decreased iron absorption; iron tablets must be taken whole and not crushed. Black, tarry stools are expected adverse effects of oral iron supplements.

A patient has been instructed to take one enteric-coated low-dose aspirin a day as part of therapy to prevent strokes. The nurse will provide which instruction when providing patient teaching about this medication? a. Aspirin needs to be taken on an empty stomach to ensure maximal absorption. b. Low-dose aspirin therapy rarely causes problems with bleeding. c. Take the medication with 6 to 8 ounces of water and with food. d. Coated tablets may be crushed if necessary for easier swallowing.

c. Take the medication with 6 to 8 ounces of water and with food. Enteric-coated aspirin is best taken with 6 to 8 ounces of water and with food to help decrease gastrointestinal upset. Enteric-coated table

When administering a bulk-forming laxative, the nurse instructs the patient to drink the medication mixed in a full 8-ounce glass of water. Which statement best explains the rationale for this instruction? a. The water acts to stimulate bowel movements. b. The water will help to reduce the bulk of the intestinal contents. c. These laxatives may cause esophageal obstruction if taken with insufficient water. d. The water acts as a lubricant to produce bowel movements.

c. These laxatives may cause esophageal obstruction if taken with insufficient water. Bulk-forming drugs increase water absorption, which results in greater total volume (bulk) of the intestinal contents. Bulk-forming laxatives tend to produce normal, formed stools. Their action is limited to the gastrointestinal tract, so there are few, if any, systemic effects. However, they need to be taken with liberal amounts of water to prevent esophageal obstruction and fecal impaction.

When reviewing the mechanisms of action of diuretics, the nurse knows that which statement is true about loop diuretics? a. They work by inhibiting aldosterone. b. They are very potent, having a diuretic effect that lasts at least 6 hours. c. They have a rapid onset of action and cause rapid diuresis. d. They are not effective when the creatinine clearance decreases below 25 mL/min.

c. They have a rapid onset of action and cause rapid diuresis. The loop diuretics have a rapid onset of action; therefore, they are useful when rapid onset is desired. Their effect lasts for about 2 hours, and a distinct advantage they have over thiazide diuretics is that their diuretic action continues even when creatinine clearance decreases below 25 mL/min.

A patient is started on a diuretic for antihypertensive therapy. The nurse expects that a drug in which class is likely to be used initially? a. Loop diuretics b. Osmotic diuretics c. Thiazide diuretics d. Potassium-sparing diuretics

c. Thiazide diuretics The Eighth Report of the Joint National Committee on Prevention, Detection, Evaluation, and Treatment of High Blood Pressure (JNC-8) guidelines reaffirmed the role of thiazide diuretics as one of the first-line treatment for hypertension. The other drug classes are not considered firstline treatments

A patient will be receiving a thrombolytic drug as part of the treatment for acute myocardial infarction. The nurse explains to the patient that this drug is used for which purpose? a. To relieve chest pain b. To prevent further clot formation c. To dissolve the clot in the coronary artery d. To control bleeding in the coronary vessels

c. To dissolve the clot in the coronary artery Thrombolytic drugs lyse, or dissolve, thrombi. They are not used to prevent further clot formation or to control bleeding. As a result of dissolving of the thrombi, chest pain may be relieved, but that is not the primary purpose of thrombolytic therapy.

When teaching a patient who has a new prescription for transdermal nitroglycerin patches, the nurse tells the patient that these patches are most appropriately used for which situation? a. To prevent low blood pressure b. To relieve shortness of breath c. To prevent the occurrence of angina d. To keep the heart rate from rising too high during exercise

c. To prevent the occurrence of angina Transdermal dosage formulations of nitroglycerin are used for the long-term prophylactic management (prevention) of angina pectoris. Transdermal nitroglycerin patches are not appropriate for the relief of shortness of breath, to prevent palpitations, or to control the heart rate during exercise.

A patient will be taking bismuth subsalicylate (Pepto-Bismol) to control diarrhea. When reviewing the patient's other ordered medications, the nurse recognizes that which medication will interact significantly with the Pepto-Bismol? a. Acetaminophen (Tylenol), an analgesic b. Levothyroxine (Synthroid), a thyroid replacement drug c. Warfarin (Coumadin), an anticoagulant d. Fluoxetine (Prozac), an antidepressant

c. Warfarin (Coumadin), an anticoagulant The oral anticoagulant warfarin is more likely to cause increased bleeding times or bruising when co-administered with adsorbents. This is thought to be because the adsorbents bind to vitamin K, which is needed to make certain clotting factors. Vitamin K is synthesized by the normal bacterial flora in the bowel.

Furosemide (Lasix) is prescribed for a patient who is about to be discharged, and the nurse provides instructions to the patient about the medication. Which statement by the nurse is correct? a. "Take this medication in the evening." b. "Avoid foods high in potassium, such as bananas, oranges, fresh vegetables, and dates." c. "If you experience weight gain, such as 5 pounds or more per week, be sure to tell your physician during your next routine visit." d. "Be sure to change positions slowly and rise slowly after sitting or lying so as to prevent dizziness and possible fainting because of blood pressure changes."

d. "Be sure to change positions slowly and rise slowly after sitting or lying so as to prevent dizziness and possible fainting because of blood pressure changes." Orthostatic hypotension is a possible problem with diuretic therapy. Foods high in potassium should be eaten more often, and the drug needs to be taken in the morning so that the diuretic effects do not interfere with sleep. A weight gain of 5 pounds or more per week must be reported immediately.

A patient has been taking a beta blocker for 4 weeks as part of his antianginal therapy. He also has type II diabetes and hyperthyroidism. When discussing possible adverse effects, the nurse will include which information? a. "Watch for unusual weight loss." b. "Monitor your pulse for increased heart rate." c. "Use the hot tub and sauna at the gym as long as time is limited to 15 minutes." d. "Monitor your blood glucose levels for possible hypoglycemia or hyperglycemia."

d. "Monitor your blood glucose levels for possible hypoglycemia or hyperglycemia." Beta blockers can cause both hypoglycemia and hyperglycemia. They may also cause weight gain if heart failure is developing, and decreased pulse rate. The use of hot tubs and saunas is not recommended because of the possibility of hypotensive episodes.

A patient on diuretic therapy calls the clinic because he's had the flu, with "terrible vomiting and diarrhea," and he has not kept anything down for 2 days. He feels weak and extremely tired. Which statement by the nurse is correct? a. "It's important to try to stay on your prescribed medication. Try to take it with sips of water." b. "Stop taking the diuretic for a few days, and then restart it when you feel better." c. "You will need an increased dosage of the diuretic because of your illness. Let me speak to the physician." d. "Please come into the clinic for an evaluation to make sure there are no complications."

d. "Please come into the clinic for an evaluation to make sure there are no complications." Vomiting and diarrhea cause fluid and electrolyte loss. The patient must not continue to take the diuretic until these problems have stopped. He needs to be checked for possible hypokalemia and dehydration. The other options are incorrect responses.

During a follow-up visit, the health care provider examines the fundus of the patient's eye. Afterward, the patient asks the nurse, "Why is he looking at my eyes when I have high blood pressure? It does not make sense to me!" What is the best response by the nurse? a. "We need to monitor for drug toxicity." b. "We must watch for increased intraocular pressure." c. "The provider is assessing for visual changes that may occur with drug therapy." d. "The provider is making sure the treatment is effective over the long term."

d. "The provider is making sure the treatment is effective over the long term." The physician would examine the fundus of a patient's eyes during antihypertensive therapy because it is a more reliable indicator than blood pressure readings of the long-term effectiveness of treatment.

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."

d. "Therapy for high blood pressure is usually lifelong." There is no cure for the disease, and treatment will be lifelong.

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."

d. "This drug is an antidote to digoxin and will help to lower the blood levels."

The nurse recognizes that use of estrogen drugs is contraindicated in which patient? a. A patient who has atrophic vaginitis b. A patient who has inoperable prostate cancer c. A woman who has just given birth and wants to prevent postpartum lactation d. A woman with a history of thrombophlebitis

d. A woman with a history of thrombophlebitis Estrogenic drugs are contraindicated in people who have active thromboembolic disorders and in those with histories of thromboembolic disease. Atrophic vaginitis and inoperable prostate cancer are potential indications for estrogen therapy. Estrogen is not used to prevent lactation.

The nurse is reviewing discharge teaching for a patient who will be taking digoxin (Lanoxin) therapy. The nurse will teach the patient to avoid which foods when taking the digoxin? a. Leafy green vegetables b. Dairy products c. Grapefruit juice d. Bran muffins

d. Bran muffins Bran, in large amounts, may decrease the absorption of oral digitalis drugs. The other foods do not affect digoxin levels.

The nurse is reviewing new medication orders for a patient who has an epidural catheter for pain relief. One of the orders is for enoxaparin (Lovenox), a low-molecular-weight heparin (LMWH). What is the nurse's priority action? a. Give the LMWH as ordered. b. Double-check the LMWH order with another nurse, and then administer as ordered. c. Stop the epidural pain medication, and then administer the LMWH. d. Contact the prescriber because the LMWH cannot be given if the patient has an epidural catheter.

d. Contact the prescriber because the LMWH cannot be given if the patient has an epidural catheter. LMWHs are contraindicated in patients with an indwelling epidural catheter; they can be given 2 hours after the epidural is removed. This is very important to remember, because giving an LMWH with an epidural has been associated with epidural hematoma.

When starting a patient on antidysrhythmic therapy, the nurse will remember that which problem is a potential adverse effect of any antidysrhythmic drug? a. Deficiency of fat-soluble vitamins b. Hyperkalemia c. Heart failure d. Dysrhythmias

d. Dysrhythmias Many antidysrhythmics are themselves capable of producing new dysrhythmias (the prodysrhythmic effect).

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 B12 b. Vitamin D c. Iron d. Folic acid

d. Folic acid 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.

A 79-year-old patient is taking a diuretic for treatment of hypertension. This patient is very independent and wants to continue to live at home. The nurse will know that which teaching point is important for this patient? a. He should take the diuretic with his evening meal. b. He should skip the diuretic dose if he plans to leave the house. c. If he feels dizzy while on this medication, he needs to stop taking it and take potassium supplements instead. d. He needs to take extra precautions when standing up because of possible orthostatic hypotension and resulting injury from falls.

d. He needs to take extra precautions when standing up because of possible orthostatic hypotension and resulting injury from falls. Caution must be exercised in the administration of diuretics to the older adults because they are more sensitive to the therapeutic effects of these drugs and are more sensitive to the adverse effects of diuretics, such as dehydration, electrolyte loss, dizziness, and syncope. Taking the diuretic with the evening meal may disrupt sleep because of nocturia. Doses should never be skipped or stopped without checking with the prescriber.

A patient has been prescribed warfarin (Coumadin) in addition to a heparin infusion. The patient asks the nurse why he has to be on two medications. The nurse's response is based on which rationale? a. The oral and injection forms work synergistically. b. The combination of heparin and an oral anticoagulant results in fewer adverse effects than heparin used alone. c. Oral anticoagulants are used to reach an adequate level of anticoagulation when heparin alone is unable to do so. d. Heparin is used to start anticoagulation so as to allow time for the blood levels of warfarin to reach adequate levels.

d. Heparin is used to start anticoagulation so as to allow time for the blood levels of warfarin to reach adequate levels. This overlap therapy is required in patients who have been receiving heparin for anticoagulation and are to be switched to warfarin so that prevention of clotting is continuous. This overlapping is done purposefully to allow time for the blood levels of warfarin to rise, so that when the heparin is eventually discontinued, therapeutic anticoagulation levels of warfarin will have been achieved. Recommendations are to continue overlap therapy of the heparin and warfarin for at least 5 days; the heparin is stopped after day 5 when the international normalized ratio (INR) is above 2.

A patient with coronary artery disease asks the nurse about the "good cholesterol" laboratory values. The nurse knows that "good cholesterol" refers to which lipids? a. Triglycerides b. Low-density lipoproteins (LDLs) c. Very-low-density lipoproteins (VLDLs) d. High-density lipoproteins (HDLs)

d. High-density lipoproteins (HDLs) HDLs are responsible for the "recycling" of cholesterol. HDLs are sometimes referred to as the "good" lipid (or good cholesterol) because they are believed to be cardioprotective. LDLs are known as the "bad" cholesterol.

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.

A patient who has been on antibiotic therapy for 2 weeks has developed persistent diarrhea. The nurse expects which medication class to be ordered to treat this diarrhea? a. Lubricants b. Adsorbents c. Anticholinergics d. Probiotics

d. Probiotics Probiotics work by replenishing bacteria that may have been destroyed by antibiotic therapy, thus restoring the balance of normal flora and suppressing the growth of diarrhea-causing bacteria.

What action is often recommended to help reduce tolerance to transdermal nitroglycerin therapy? a. Omit a dose once a week. b. Leave the patch on for 2 days at a time. c. Cut the patch in half for 1 week until the tolerance subsides. d. Remove the patch at bedtime, and then apply a new one in the morning.

d. Remove the patch at bedtime, and then apply a new one in the morning. To prevent tolerance, remove the transdermal patch at night for 8 hours, and apply a new patch in the morning. Transdermal patches must never be cut or left on for 2 days, and doses must not be omitted.

A patient is complaining of excessive and painful gas. The nurse checks the patient's medication orders and prepares to administer which drug for this problem? a. Famotidine (Pepcid) b. Aluminum hydroxide and magnesium hydroxide (Maalox or Mylanta) c. Calcium carbonate (Tums) d. Simethicone (Mylicon)

d. Simethicone (Mylicon) Simethicone alters the elasticity of mucus-coated bubbles, causing them to break, and is an overthe-counter antiflatulent.

The nurse will monitor a patient for signs and symptoms of hyperkalemia if the patient is taking which of these diuretics? a. Hydrochlorothiazide (HydroDIURIL) b. Furosemide (Lasix) c. Acetazolamide (Diamox) d. Spironolactone (Aldactone)

d. Spironolactone (Aldactone) Spironolactone (Aldactone) is a potassium-sparing diuretic, and patients taking this drug must be monitored for signs of hyperkalemia. The other drugs do not cause hyperkalemia but instead cause hypokalemia.

The nurse is reviewing the medical record of a patient before giving a new order for iron sucrose (Venofer). Which statement regarding the administration of iron sucrose is correct? a. The medication is given with food to reduce gastric distress. b. Iron sucrose is contraindicated if the patient has renal disease. c. A test dose will be administered before the full dose is given. d. The nurse will monitor the patient for hypotension during the infusion.

d. The nurse will monitor the patient for hypotension during the infusion. Iron sucrose (Venofer) is an injectable iron product indicated for the treatment of iron-deficiency anemia in patients with chronic renal disease. It is also used for patients without kidney disease. Its risk of precipitating anaphylaxis is much less than that of iron dextran, and a test dose is not required. Hypotension is the most common adverse effect and appears to be related to infusion rate. Low-weight elderly patients appear to be at greatest risk for hypotension.

A patient accidentally took an overdose of the anticoagulant warfarin (Coumadin), and the nurse is preparing to administer vitamin K as an antidote. Which statement about vitamin K is accurate? a. The vitamin K dose will be given intramuscularly. b. The patient will take oral doses of vitamin K after the initial injection. c. The vitamin K cannot be given if the patient has renal disease. d. The patient will be unresponsive to warfarin therapy for 1 week after the vitamin K is given.

d. The patient will be unresponsive to warfarin therapy for 1 week after the vitamin K is given. When vitamin K is used as an antidote to warfarin therapy, the patient becomes unresponsive to warfarin for approximately 1 week after vitamin K administration. The use of vitamin K products is contraindicated in patients who are in the last few weeks of pregnancy and in patients with severe hepatic disease. Vitamin K is given subcutaneously and not intramuscularly when used to reverse warfarin effects.

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.

d. The specific cause of the anemia needs to be determined before treatment. 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.

When administering heparin subcutaneously, the nurse will follow which procedure? a. Aspirating the syringe before injecting the medication b. Massaging the site after injection c. Applying heat to the injection site d. Using a 1/2 to 5/8inch 25- to 28-gauge needle

d. Using a 1/2 to 5/8inch 25- to 28-gauge needle A 1/2 to 5/8inch 25- to 28-gauge needle is the correct needle to use for a subcutaneous heparin injection. The other options would encourage hematoma formation at the injection site.

A 51-year-old woman will be taking selective estrogen receptor modulators (SERMs) as part of treatment for postmenopausal osteoporosis. The nurse reviews potential contraindications, including which condition? a. Hypocalcemia b. Breast cancer c. Stress fractures d. Venous thromboembolism

d. Venous thromboembolism SERMs such as raloxifene are contraindicated in women with a venous thromboembolic disorder, including deep vein thrombosis, pulmonary embolism, or a history of such disorders. The other options are incorrect.
