Pharmacology HESI 55 Questions 2023
1. A client diagnosed with angina has been prescribed nitrate isosorbide dinitrate. Which instruction should the practical nurse reinforce in this client's teaching?
- A. Discontinue the medication if dizziness occurs.
- B. Avoid getting up quickly. Always rise slowly.
- C. Take the medication with or without food.
- D. Increase your intake of potassium-rich foods.
Correct answer: B
Rationale: The correct instruction that the practical nurse should reinforce with a client prescribed nitrate isosorbide dinitrate is to avoid getting up quickly and to rise slowly. Nitrates can cause orthostatic hypotension, a sudden drop in blood pressure when changing positions. By rising slowly, the client can prevent the occurrence of orthostatic hypotension and its associated symptoms. Choices A, C, and D are incorrect because discontinuing the medication without consulting a healthcare provider can be dangerous, taking the medication with or without food does not impact its effectiveness, and increasing potassium intake is not directly related to the use of nitrate isosorbide dinitrate.
2. A practical nurse (PN) is reviewing teaching with the client and/or significant others about the concurrent use of benztropine and olanzapine to manage psychotic behavior. What information should the PN reinforce?
- A. Benztropine will reduce olanzapine's side effect of urinary retention.
- B. Benztropine potentiates the effect of olanzapine.
- C. Benztropine is used to control the side effects of olanzapine.
- D. The combined effect of these drugs will modify psychotic behavior.
Correct answer: C
Rationale: The correct answer is C because benztropine, an anticholinergic drug, is used to control extrapyramidal symptoms associated with olanzapine use. Choice A is incorrect because benztropine does not directly reduce olanzapine's side effect of urinary retention. Choice B is incorrect as benztropine does not potentiate the effect of olanzapine; its main role is to counteract extrapyramidal symptoms. Choice D is incorrect because the primary purpose of using benztropine alongside olanzapine is to manage side effects, not specifically to modify psychotic behavior.
3. A client taking long-term steroids also has ranitidine prescribed. The nurse provides which explanation as to why these drugs are given together?
- A. Ranitidine reduces the risk of ulcers associated with steroids.
- B. Ranitidine decreases the risk of infection associated with steroids.
- C. Ranitidine decreases blood sugar elevations associated with steroids.
- D. Ranitidine reduces sodium retention associated with steroid usage.
Correct answer: A
Rationale: The correct answer is A. Ranitidine is prescribed with long-term steroids to reduce the risk of ulcers associated with steroid therapy. Although steroids can increase the risk of ulcers due to their effect on the gastrointestinal system, ranitidine works by reducing stomach acid production, thus helping to prevent ulcer formation. Choices B, C, and D are incorrect as ranitidine is not given to decrease the risk of infection, reduce blood sugar elevations, or reduce sodium retention associated with steroid usage.
4. A client is prescribed an antibiotic for a urinary tract infection (UTI). What instruction should the practical nurse provide to the client to ensure the effectiveness of the medication?
- A. Take the medication with food.
- B. Increase fluid intake.
- C. Complete the full course of the medication.
- D. Avoid dairy products.
Correct answer: C
Rationale: The practical nurse should instruct the client to complete the full course of the antibiotic to ensure the infection is fully treated and to prevent the development of antibiotic resistance. Completing the full course of antibiotics helps to eradicate the infection completely and reduces the risk of bacteria developing resistance to the medication. Choices A, B, and D are not directly related to ensuring the effectiveness of the antibiotic. While taking medication with food or increasing fluid intake can be beneficial in general, the crucial instruction in this case is to complete the full course of the antibiotic.
5. A client with chronic kidney disease is prescribed erythropoietin. The nurse should monitor for which potential adverse effect?
- A. Hypertension
- B. Hypotension
- C. Tachycardia
- D. Bradycardia
Correct answer: A
Rationale: Erythropoietin is a medication commonly used to stimulate red blood cell production in individuals with chronic kidney disease. One of the potential adverse effects of erythropoietin therapy is hypertension. The increased production of red blood cells can lead to elevated blood pressure levels. Therefore, monitoring for hypertension is essential to ensure the client's safety and well-being while on this medication. Choices B, C, and D are incorrect because hypotension, tachycardia, and bradycardia are not typically associated with erythropoietin therapy. Hypertension is the primary adverse effect to monitor in this case.
