HESI Practice Test Pharmacology
1. When planning to administer the antiulcer GI agent sucralfate, what instruction should the nurse provide regarding administration?
- A. Administer sucralfate once a day
- B. Assess for secondary candida infection
- C. Monitor electrolyte imbalance
- D. Give sucralfate on an empty stomach
Correct answer: D
Rationale: Sucralfate is most effective when taken on an empty stomach. This allows the medication to form a protective layer over the ulcer, promoting healing and symptom relief. Administering sucralfate with or after meals may reduce its efficacy as it may bind to food instead of coating the ulcer site.
2. A client has been prescribed losartan. Which change in data indicates to the practical nurse (PN) that the desired effect of this medication has been achieved?
- A. Dependent edema reduced from +3 to +1.
- B. Serum HDL increased from 35 to 55 mg/dL.
- C. Pulse rate reduced from 150 to 90 beats/min.
- D. Blood pressure reduced from 160/90 to 130/80 mm Hg.
Correct answer: D
Rationale: The correct answer is D. Losartan is prescribed for the treatment of hypertension. The desired effect of losartan is to reduce blood pressure. Therefore, a reduction in blood pressure from 160/90 to 130/80 mm Hg indicates that the desired effect of the medication has been achieved. Choices A, B, and C are not specific effects of losartan and do not directly relate to the expected outcomes of this medication. Dependent edema, serum HDL levels, and pulse rate are not typically influenced by losartan, making choices A, B, and C incorrect.
3. A client with anxiety is prescribed alprazolam. What instruction should the nurse include in the client's teaching plan?
- A. Take this medication with food.
- B. Avoid activities that require alertness.
- C. Do not stop taking this medication abruptly.
- D. This medication may cause drowsiness.
Correct answer: C
Rationale: The correct answer is C: 'Do not stop taking this medication abruptly.' Alprazolam should not be stopped suddenly as it can lead to withdrawal symptoms. It is important for clients to taper off the medication gradually under medical supervision to prevent adverse effects. Choices A, B, and D are incorrect. Choice A is irrelevant to alprazolam administration instructions. Choice B, 'Avoid activities that require alertness,' is not the priority teaching point for alprazolam. Choice D, 'This medication may cause drowsiness,' is a common side effect of alprazolam but not the most critical instruction to include in the teaching plan.
4. What instructions should the PN reinforce with the client regarding the newly prescribed medications isosorbide dinitrate and hydrochlorothiazide?
- A. Instruct the client to use a soft bristle toothbrush.
- B. Instruct the client to slowly rise from a sitting or lying down position.
- C. Instruct the client to elevate their legs above the level of their heart.
- D. Instruct the client to limit the amount of fiber in their diet.
Correct answer: B
Rationale: The correct instruction for the client is to slowly rise from a sitting or lying down position. Isosorbide dinitrate, a nitrate, and hydrochlorothiazide, a diuretic, can both cause hypotension. When used together, their additive effects can further lower blood pressure, leading to orthostatic hypotension. Instructing the client to change positions slowly helps prevent a sudden drop in blood pressure, reducing the risk of dizziness or falls. Choices A, C, and D are incorrect because they do not directly address the potential side effect of hypotension associated with the prescribed medications. Using a soft bristle toothbrush, elevating legs above the heart level, or limiting fiber intake are not specific instructions to mitigate the risk of orthostatic hypotension.
5. Which nursing intervention is most important when caring for a client receiving aspirin 600mg po QID?
- A. Monitor temperature q4h
- B. Use 10-point pain scale to assess pain
- C. Assess for dyspepsia and nausea
- D. Check stool for occult blood
Correct answer: D
Rationale: The correct answer is to check the stool for occult blood when caring for a client receiving aspirin 600mg po QID. Aspirin can lead to gastrointestinal bleeding, and checking for occult blood in the stool is essential to monitor for this serious adverse effect. Monitoring temperature, assessing pain, and checking for dyspepsia and nausea are important interventions but not as critical as monitoring for gastrointestinal bleeding when a client is receiving aspirin.
