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. How does omeprazole work in treating a peptic ulcer?
- A. Increasing the production of gastric acid
- B. Neutralizing stomach acid
- C. Coating the stomach lining
- D. Reducing gastric acid secretion
Correct answer: D
Rationale: Omeprazole is a proton pump inhibitor that works by reducing gastric acid secretion. By inhibiting the enzyme responsible for pumping acid into the stomach, omeprazole helps decrease the acidity level in the stomach, providing relief from peptic ulcers. Option A is incorrect because omeprazole does not increase gastric acid production; instead, it decreases it. Option B is incorrect as omeprazole does not neutralize existing stomach acid but rather reduces its secretion. Option C is incorrect as omeprazole does not coat the stomach lining but acts on reducing acid secretion.
3. A client is prescribed cyclobenzaprine for muscle spasms. The nurse should instruct the client to avoid which substance while taking this medication?
- A. Alcohol
- B. Caffeine
- C. Nicotine
- D. Dairy products
Correct answer: A
Rationale: The correct answer is A: Alcohol. When taking cyclobenzaprine, it is important to avoid alcohol as it can potentiate the central nervous system depressant effects of the medication. This interaction can lead to increased drowsiness, dizziness, and impaired coordination. Therefore, it is essential for the client to refrain from alcohol consumption while on cyclobenzaprine to prevent these adverse effects and ensure their safety. Choices B, C, and D are incorrect because caffeine, nicotine, and dairy products do not have significant interactions with cyclobenzaprine. While caffeine and nicotine may have stimulant effects that could theoretically counteract some of the sedative effects of cyclobenzaprine, they are not contraindicated. Dairy products, on the other hand, do not interact with cyclobenzaprine and can be consumed safely.
4. When educating a client about the adverse effects of conjunctivitis, what is a serious condition that requires prompt attention?
- A. Contact lens irritation
- B. Decreased sex drive
- C. Brown spots on the skin
- D. Epigastric pain unrelieved by antacids
Correct answer: D
Rationale: Epigastric pain unrelieved by antacids is a concerning symptom that may indicate a more serious underlying condition such as a perforated ulcer. This symptom requires immediate medical attention to prevent further complications.
5. A client with a diagnosis of schizophrenia is prescribed risperidone. The nurse should monitor the client for which potential side effect?
- A. Weight gain
- B. Dry mouth
- C. Nausea
- D. Headache
Correct answer: A
Rationale: When a client is prescribed risperidone, it is essential to monitor for potential side effects. Weight gain is a common side effect of risperidone, so the nurse should closely monitor the client's weight throughout the treatment. This monitoring helps in early detection of weight changes and allows for timely interventions to prevent further complications.
