NURS 6521 QUESTION BANK 2 ASSIGNMENTS – WALDEN
Question 1
A clinic nurse has been assigned a 49-year-old female patient who has a history of diabetes. A recent diagnosis of hypertension has been made, and the patient has been prescribed a thiazide diuretic and labetalol. The patient will be scheduled to return to the clinic once a month for the next 6 months. A priority action by the nurse will be to
Response Feedback:
Monitoring of blood pressure would be the priority assessment in the care of this patient. Questioning the patient about her dietary intake and weighing her would be appropriate, but secondary in importance. It is unnecessary to monitor the patient’s respiratory rate.
Question 2
A 55-year-old man’s hypertension has not responded adequately to his current medication regimen consisting or an ACE inhibitor, a beta-blocker and a thiazide diuretic. As a result, he will soon begin taking hydralazine (Apresoline) in addition to his existing antihypertensives. The addition of this medication to his regimen means that the nurse must prioritize which of the following nursing actions?

Response Feedback:
Hydralazine is associated with an increase in cardiac output that can precipitate palpitations, tachycardia, and angina. As a result, there is a need for astute cardiac assessment. The use of hydralazine does not directly necessitate close monitoring of electrolytes or blood sugars, even though these are prudent assessment measures. There is a risk of dizziness and possibly falls with the use of any antihypertensive, but it is unnecessary to supervise all of the patient’s ADLs.
Question 3
A 39-year-old African-American male is 25 pounds overweight and has been diagnosed with hypertension after three consecutive above-normal blood pressure readings. The most likely initial drug therapy for this patient will be
Response Feedback:
The patient would most likely be prescribed a diuretic in combination with diet and other lifestyle changes. African-American men are at increased risk for developing hypertension and tend to respond differently to antihypertensive therapy. The research shows that African-American men are most responsive to single-drug therapy and diuretics. The use of a calcium channel blocker and/or alpha-adrenergic blocker would follow if he is unresponsive to the diuretic in combination with diet and other lifestyle changes. African Americans tend to be less responsive to ACE inhibitors and beta blockers.

Question 4
A patient is brought to the emergency department in hypertensive crisis. Nitroprusside is administered intravenously. The patient experiences diaphoresis and dizziness. Which of the following is the appropriate action by the nurse?
Response Feedback:
Administering nitroprusside too quickly can result in abdominal pain, apprehension, diaphoresis, dizziness, headache, muscle twitching, nausea, palpitations, restlessness, retching, and retrosternal discomfort. The nurse should quickly inform the prescriber and slow the infusion. Symptoms quickly subside when the nitroprusside infusion is slowed or stopped, and usually do not return when the infusion resumes at a slower rate. Consulting the prescriber for a dose change would not help; the rate of drug administration is the issue. Continuing to give the nitroprusside at the ordered rate could be fatal.
Question 5
Several months of treatment with a statin accompanied by lifestyle modifications have failed to appreciably improve a patient’s cholesterol levels. Consequently, the patient has been prescribed cholestyramine. The nurse should recognize that this drugs achieves its therapeutic effect by
Response Feedback:
Unlike statins, which work by decreasing the synthesis of cholesterol, the bile acid sequestrants such as cholestyramine promote the oxidation of cholesterol to bile acids. Bile acid sequestrants do not promote vasodilation or bind HDL to LDL.
Question 6
A 58-year-old man is admitted to the emergency department. A diagnosis of severe digoxin toxicity is made. Bradycardia is present, and an electrocardiogram (ECG) confirms toxicity. The nurse will administer which of the following drugs?
Response Feedback:
Digoxin immune fab is used as the antidote to digoxin toxicity. The other drugs would not be used to treat digoxin toxicity. The patient could be taking furosemide as part of his drug regimen for heart failure.
Question 7
A resident of a long-term care facility receives 12.5 mg metoprolol (Lopressor) at 8 AM and 8 PM daily. Before administering this drug, the nurse should perform and document what assessments?
Response Feedback:
Metoprolol has a profound effect on both blood pressure and heart rate. Consequently, the nurse should assess these parameters prior to administering the drug. Assessments related to pain, respiratory status, cognition, and temperature are not central to the administration of a beta blocker.
Question 8
A nurse who provides care in a busy clinic is aware of the high incidence and prevalence of hyperlipidemia and the consequent need for antihyperlipidemics in many patients. Treatment of high cholesterol using statins would be contraindicated in which of the following patients?
Response Feedback:
Active liver disease is a contraindication to the use of statins. As well, heavy alcohol use increases the risk of liver dysfunction. Respiratory disease, recent surgery, and organic cognitive deficits do not preclude the use of statins for high cholesterol. NURS 6521 QUESTION BANK 2 ASSIGNMENTS – WALDEN
Question 9
A nurse is caring for a male patient who has a diagnosis of coronary artery disease (CAD). His drug therapy includes lovastatin. Because the patient has a history of severe renal disease, the nurse will assess for which of the following?
Response Feedback:
Patients with severe renal disease may have an increased plasma concentration of lovastatin because 10% of the drug is eliminated in the urine. Patients with renal disorders are not likely to experience a decrease in LDL or an increase in the statin tolerance level.
Question 10
A nurse is caring for a patient who is admitted into the cardiac care unit with acute, decompensated heart failure. Nesiritide (Natrecor) has been ordered. When preparing for administration of the drug, the nurse will
Response Feedback:
Nesiritide must be reconstituted and then further diluted for infusion. Reconstitute one vial by adding 5 mL of diluent that has been removed from a 250-mL plastic IV bag. Do not shake the vial. Rock the vial gently so that all surfaces, including the stopper, are in contact with the diluent. Add the entire contents of the reconstituted vial back to the 250-mL plastic IV bag and invert the bag several times to ensure complete mixing. Use the reconstituted nesiritide solution within 24 hours. The initial IV bolus must be drawn from the prepared infusion bag and administered over approximately 60 seconds through an IV port.
Question 11
A 70-year-old woman with a history of atrial fibrillation takes digoxin and verapamil to control her health problem. Verapamil achieves a therapeutic effect by
Response Feedback:
Verapamil acts by inhibiting the movement of calcium ions across the cardiac and arterial muscle cell membrane. It works preferentially in “slow response” myocardial tissue, such as the SA and AV nodes. Beta blockers inhibit adrenergic receptors and Class IB antiarrhythmics are among the drugs that decrease sodium and potassium conduction. Lidocaine weakens phase 4 diastolic depolarization and decreases the action potential duration and the effective refractory period of Purkinje fibers and ventricular muscle.
