Pharmacology HESI 55 Questions 2023
1. A client receiving enalapril reports a persistent dry cough. The nurse should explain that this side effect is related to which medication action?
- A. It reduces the production of angiotensin II.
- B. It increases the production of angiotensin II.
- C. It causes increased production of bradykinin.
- D. It increases the production of aldosterone.
Correct answer: C
Rationale: The correct answer is C. Enalapril, an ACE inhibitor, inhibits the conversion of angiotensin I to angiotensin II, leading to increased levels of bradykinin. The accumulation of bradykinin is responsible for the persistent dry cough associated with ACE inhibitors like enalapril. Choices A, B, and D are incorrect because enalapril does not directly affect the production of angiotensin II or aldosterone. Instead, it primarily impacts the renin-angiotensin-aldosterone system by inhibiting the conversion of angiotensin I to angiotensin II, leading to bradykinin accumulation.
2. A client diagnosed with multiple sclerosis self-administers beta-1 interferon subcutaneously
- A. Explain to the client that the medication dose may need to be increased
- B. Instruct the client to withhold the drug until the next exacerbation
- C. Advise the client to consult the healthcare provider as soon as possible
- D. Encourage the client to continue taking the medication
Correct answer: D
Rationale: Encouraging the client to continue taking the medication is crucial in the management of multiple sclerosis. Beta-1 interferon is a disease-modifying drug used to reduce the frequency and severity of relapses in multiple sclerosis. Discontinuing the medication without medical advice can lead to disease exacerbation. It is essential for the client to maintain regular dosing to achieve optimal therapeutic effects and disease control.
3. A client with a history of heart failure is prescribed spironolactone. The nurse should monitor for which potential side effect?
- A. Hyperkalemia
- B. Hypokalemia
- C. Hyponatremia
- D. Hypernatremia
Correct answer: A
Rationale: The correct answer is A: Hyperkalemia. Spironolactone is a potassium-sparing diuretic, which can lead to an excess of potassium in the body, causing hyperkalemia. This medication inhibits the action of aldosterone, leading to decreased potassium excretion and potential retention. Monitoring potassium levels is essential to prevent complications such as cardiac arrhythmias, especially in clients with heart failure.
4. The healthcare provider is assessing the effectiveness of the drug amiodarone. Which client statement best indicates that the drug has been effective?
- A. I have not had as many spells of angina.
- B. I have not had as much swelling in my ankles lately.
- C. My doctor told me my cholesterol levels were improving with each visit.
- D. I do not notice as many irregular heartbeats as before I started taking this medication.
Correct answer: D
Rationale: The correct answer is option D. The effectiveness of amiodarone is best assessed by a reduction in irregular heartbeats since it is primarily used to treat ventricular dysrhythmias. This drug's main purpose is to control irregular heart rhythms, so a decrease in irregular heartbeats indicates its effectiveness. Options A, B, and C are incorrect because amiodarone is not primarily used to address angina, ankle swelling, or cholesterol levels, so improvements in these areas do not directly reflect the drug's effectiveness.
5. A practical nurse (PN) is preparing to administer a scheduled dose of furosemide to a client. Which laboratory value is most important for the PN to review before administering the medication?
- A. Serum calcium level
- B. Serum potassium level
- C. Serum sodium level
- D. Serum magnesium level
Correct answer: B
Rationale: The correct answer is to review the client's serum potassium level before administering furosemide. Furosemide, a loop diuretic, can lead to hypokalemia, making it crucial to assess potassium levels to prevent potential complications like cardiac arrhythmias associated with low potassium levels.
