microwave during cooking. A cellular phone can be used but should be held in the
right hand.
8. Answer C is correct. The dye used in the procedure can cause a decrease in renal
function. The clients renal function should be assessed and changes reported to the
doctor immediately. Answer A is incorrect because the clients allergies should be
checked prior to the procedure, not after the procedure. The femoral artery is
commonly used as the site for a catheterization. Answer B is incorrect because the
pulses should be checked distal to the site. Answer D is incorrect because the
permit should be signed prior to the procedure.
9. Answer D is correct. The other name for Buergers disease is thromboangiitis
obliterans. Answer A is incorrect because pheochromocytoma is an adrenal tumor.
Answer B is incorrect because intermittent claudication is pain in an extremity when
walking. Answer C is incorrect because Kawasaki disease is an acute vasculitis that
can result in an aneurysm in the thoracic area.
10. Answer C is correct. Clients with abdominal aortic aneurysms often complain of
nausea, lower back pain, and feeling their heart beat in the abdomen. Answer A is
incorrect because a headache is a symptom of a cerebral aneurysm. Answer B is
incorrect because, although the client with an abdominal aneurysm might have
shortness of breath, this symptom is not particular to during sleep. Answer D is
incorrect because difficulty voiding is not associated with an abdominal aneurysm.
11. Answer A is correct. The normal CVP reading is 812 mm Hg. A reading of 4
indicates possible bleeding and fluid loss. The nurse should administer IV fluid as
ordered. Answers B, C, and D are incorrect actions at this time.
12. Answer B is correct. While taking beta blockers, the client should be taught to
check his pulse daily. This category of blood pressure drugs slows the pulse rate.
Answer A is incorrect because the client can operate heavy equipment when taking
beta blockers. Answer C is incorrect because beta blockers reach their optimal
levels within days of beginning the medication. Answer D is incorrect because there
is no need to increase potassium-rich foods when taking beta blockers. There is a
need to increase potassium-rich foods while taking diuretics that are not potassiumsparing.
13. Answer C is correct. The peel of a baked potato contains large amounts of
potassium. Answers A, B, and D contain lesser amounts of potassium and are
therefore incorrect.
14. Answer C is correct. Palm oil and coconut oil are extremely high in cholesterol.
These oils contribute to coronary artery disease. Answers A and B are incorrect
because these oils are recommended for clients with coronary artery disease.
Answer D is incorrect because canola oil contains less fat and cholesterol than palm
oil.
15. Answer B is correct. Because simvastatin (Zocor) can damage the liver, liver
enzymes should be checked every six months. Answer A is incorrect because this
medication should not be taken with grapefruit juice. Answer C is incorrect because
Zocor should be taken at night for optimal absorption. Answer D is incorrect
because weakness or drowsiness is not associated with Zocor. It is true, however,
that extreme muscle soreness and weakness while taking Zocar can be related to
rhabdomylysis. Rhabdomylysis is a muscle-wasting disorder.
16. Answer B is correct. Lisinopril (Zestril) can cause postural hypotension. The
client should be taught to supine for approximately 34 hours after the initial dose.
The blood pressure should be checked frequently to determine the effects of the
medication. Answer A is incorrect because lisinopril is an ACE inhibitor and does not
have a direct effect on the pulse rate. Answer C is incorrect because lisinopril does
not lower cholesterol levels. Answer D is incorrect because there is no need to
increase folic acid while taking lisinopril.
17. Answer D is correct. A hacking cough, often associated with
angiotensinconverting agents, is an untoward effect that should be reported to the
doctor. The cough might indicate an allergic reaction to the medication. Answer A is
incorrect because the client might experience dizziness upon arising. Answer B is
incorrect because occasional nausea is not associated with an untoward effect of
angiotensinconverting agents. Answer C is incorrect because pedal edema is
associated with fluid retention and peripheral vascular disease, not angiotensinconverting agents.
18. Answer C is correct. The medication should be kept in a brown bottle because
light deteriorates the medication. Answer A is incorrect because the client can take
one pill every five minutes times three doses. If the pain does not subside, he
should go to the emergency department immediately. Answer B is incorrect because
a burning sensation is expected. Answer D is incorrect because the supply of
nitroglycerine should be refilled every six months.
19. Answer D is correct. Clients with a pacemaker or an internal defibrillator should
not have a magnetic resonance imaging test. Answers A and B are incorrect
because a client with a pacemaker can use a cellular phone or carry a pager if the
device is used on the opposite side of the pacemaker. Answer C is incorrect because
the client can travel by airplane. Use of a handheld metal detector is
contraindicated.
20. Answer A is correct. The client taking digitalis (Lanoxin) can avoid toxicity by
increasing the amount of fiber in his diet. The bran muffin and orange juice provide
the most fiber and ensure a diet that includes potassium (in the orange juice).
Potassium has to be consumed in moderate amounts to avoid toxicity. Answers B, C,
and D are incorrect because they are lower in fiber.
21. Answer C is correct. The signs of digitalis toxicity are halos around lights,
brachycardia, nausea, and vomiting. Answer A is incorrect because the client will
experience brachycardia not tachycardia. Hypotension can occur but is not a sign of
toxicity, so answer B is incorrect. Answer D is incorrect because a client with
constipation, not a client with diarrhea, is more likely to be toxic.
22. Answer A is correct. The white lead or negative lead is placed on the clients
right side at the second intercostal space. Answers B, C, and D are incorrect
because the negative lead is not placed at these locations.
23. Answer A is correct. If the pulse rate is less than 100 beats per minute in the
infant, the rate should be reported to the physician. Answers B and C are incorrect
because the nurse should not administer the medication if the pulse rate is less
than 100 beats per minute. Answer D is incorrect because the nurse should report
the finding.
24. Answer A is correct. Amiodarone (Cordarone) can be used to treat premature
ventricular contractions. This drug, along with lidocaine and magnesium sulfate, will
slow the heart rate. Answers B and C are incorrect because both these drugs speed
the heart rate. Answer D is incorrect because enoxaparin (Lovenox) is a heparin
derivative used as an anticoagulant.
25. Answer B is correct. When defibrillation is performed, three quick successive
shocks are delivered with the third at 360 Joules. Answer A is incorrect because the
third shock should be at 360 Joules. Answers C and D are incorrect because 400 and
600 Joules are too high.
26. Answer A is correct. The nurse should be ready to apply oxygen when caring for
the client experiencing chest pain. Using standard protocol, oxygen can be
administered to increase the oxygenation of the myocardium. Morphine can be
administered after acquiring an order, so answer B is incorrect. Answer C is incorrect
because at this time it is not necessary to defibrillate the client. Answer D is
incorrect because a complete history should be taken when the client is stable.
27. Answer C is correct. The primary responsibility of the nurse is to obtain the vital
signs. The doctor is primarily responsible for explaining the procedure, checking the
laboratory results for a prothrombin time, and obtaining a permit; therefore answers
A, B, and D are incorrect.
28. Answer D is correct. Checking the pulse in the procedure extremity is imperative
because a clot might be present. A clot will result in decreased pulse rate and
strength. Answers A and B are incorrect because checking for allergies and
withholding fluids should be done prior to the procedure. The client should be
instructed to drink more after the procedure to increase the excretion of the dye by
the kidneys. Answer C is incorrect because the client should keep the leg straight.
29. Answer B is correct. Troponin levels can remain elevated for as long as two
weeks. If the client had an MI two weeks ago, the creatine kinase (CK-MB) will most
likely have returned to normal; therefore, answer A is incorrect. Answers C and D
are incorrect because they can be elevated with an MI but are not specific to this
condition.
30. Answer A is correct. Muffled heart sounds and a lack of drainage from the
mediastinal tube indicate cardiac tamponade or fluid around the heart. This must be
reported immediately to the physician. Answer B is incorrect because rechecking
the vital signs wastes valuable time. Answer C is incorrect because there is no data
to support the need for pain medication and it might lower the blood pressure.
Answer D is incorrect because decreasing the intravenous flow rate can further
shock.
31. Answer B is correct. Puffed rice, puffed wheat, and shredded wheat have less
sodium than any of the other choices. Answers A, C, and D are incorrect for this
reason.
32. Answer D is correct. To ensure accuracy of the BNP laboratory test, Primacor
should be stopped two hours prior to the test. Answers A, B, and C are incorrect
actions.
33. Answer C is correct. Constipation can lead to an elevated level when taking
sodium warfarin. Both diarrhea and constipation can affect the absorption of this
medication. Answer A is incorrect because the medication can be taken with fruit
juice or other liquids. Answer B is incorrect because the client should not exceed
one serving of green leafy vegetables per week. Answer D is incorrect because
sodium is taken orally, not by injection.
34. Answer C is correct. The clients symptoms, while vague, can indicate a
myocardial infarction. Taking the vital signs and contacting the physician will allow
the doctor to order laboratory tests and an ECG to rule out an MI. Answers A, B, and
D are incorrect because they waste time that could be vital to ensure life and
improve the prognosis.
35. Answer A is correct. The other name for vitamin K is AquaMEPHYTON. Answer B
is incorrect because physostigmine is Antilirium, an anticholinesterase medication
used to reverse the effects of diazepam (Valium). Answer C is incorrect because
ropivacaine is Naropin, a drug used as a local anesthetic. Answer D is incorrect
because methimazole is Tapazole, a drug used to treat hypothyroidism.
36. Answer C is correct. Symptoms of left-sided congestive heart failure include
jugular vein distention; coughing with frothy, pink-tinged sputum; and shortness of
breath. Answers A and B are symptoms of right-sided congestive failure. Answer D
is incorrect because fatigue is not specific to a diagnosis of left-sided congestive
heart failure.
schedule the client for a Doppler study. Answer D is incorrect because applying a
heating pad to the extremity will be ordered by the doctor after the client is fully
assessed.
43. Answer B is correct. Raynauds phenomena is a vascular spasm occurring when
the client is exposed to cold. The hands, nose, and chin are commonly affected.
Wearing mittens when is exposed to cold will help decrease the symptoms of
Raynauds phenomena. Answer A is incorrect because there is no correlation to
keeping the feet elevated and the incidence of Raynauds. Answer C is incorrect
because caffeine intake is not associated with Raynauds phenomena. Answer D is
incorrect because Raynauds phenomena is not a problem associated with lung
disorders.
44. Answer C is correct. Buergers disease results when spasms of the arteries and
veins occur, primarily in the lower extremities. These spasms result in blood clot
formation and eventual destruction of the vessels. Answer A is incorrect because
thrombophlebitis is a blood clot with an inflammation of the vein. Answer B is
incorrect because coronary thrombosis is a clot in the coronary arteries. Answer D is
incorrect because arteritis is an inflammation of the arteries.
45. Answer A is correct. To correctly assess the CVP, the nurse should place the
client in a supine position. The zero of the manometer should be placed at the fifth
intercostals space, mid-axillary line (phlebostatic axis). Answers B, C, and D are
incorrect because they will not give a correct reading.
46. Metformin (Glucophage) needs to be withheld 24 hours before and for 48 hours
after cardiac catheterization because of the injection of contrast medium during the
procedure. If the contrast medium affects kidney function, with metformin in the
system, the client would be at increased risk for lactic acidosis. The medications in
the remaining options do not need to be withheld 24 hours before and 48 hours
after cardiac catheterization.
47. Normal sinus rhythm is defined as a regular rhythm, with an overall rate of 60 to
100 beats/minute. The PR and QRS measurements are normal, measuring 0.12 to
0.20 second and 0.04 to 0.10 second, respectively.
48. Sudden loss of electrocardiographic complexes indicates ventricular asystole or
possibly electrode displacement. Accurate assessment of the client and equipment
is necessary to determine the cause and identify the appropriate intervention. The
remaining options are secondary to client assessment.
49. Premature ventricular contractions can cause hemodynamic compromise.
Therefore, the priority is to monitor the blood pressure and oxygen saturation. The
shortened ventricular filling time can lead to decreased cardiac output. The client
may be asymptomatic or may feel palpitations. Premature ventricular contractions
can be caused by cardiac disorders, states of hypoxemia, or by any number of
