HESI Practice Test Pharmacology
1. A client is prescribed diazepam for muscle spasms. What instruction should the nurse include in the client's teaching plan?
- A. Avoid drinking alcohol
- B. Take with food to avoid gastrointestinal upset
- C. Increase fluid intake
- D. Take medication with grapefruit juice
Correct answer: A
Rationale: The correct instruction for a client prescribed diazepam for muscle spasms is to avoid drinking alcohol. Diazepam can cause drowsiness and enhance the effects of alcohol, leading to increased sedation and impaired cognitive function. Clients should be advised to avoid alcohol consumption while taking diazepam to prevent these adverse effects and ensure their safety.
2. A client with a diagnosis of generalized anxiety disorder is prescribed buspirone. The nurse should instruct the client that this medication may have which potential side effect?
- A. Drowsiness
- B. Dry mouth
- C. Nausea
- D. Headache
Correct answer: A
Rationale: The correct potential side effect of buspirone is drowsiness. It is important for clients to be informed about this side effect, as it can affect their ability to perform tasks that require full alertness, such as driving. Clients should be advised to avoid activities that require mental alertness until they know how the medication affects them. Dry mouth is a common side effect of some other medications used for anxiety, such as benzodiazepines. Nausea and headache are not typically associated with buspirone use.
3. 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.
4. The client is receiving vancomycin, and the nurse plans to draw blood for a peak and trough to determine... the best timing for these levels?
- A. Midway through administration of the IV dose and 30 minutes before the next
- B. Two hours after completion of the IV dose and 30 minutes before the next
- C. Two hours after completion of the IV dose and one hour before the next
- D. Immediately after completion of the IV dose and 30 minutes before
Correct answer: B
Rationale: To accurately determine peak and trough levels of vancomycin, blood should be drawn two hours after the completion of the IV dose and 30 minutes before the next dose. This timing allows for appropriate assessment of the drug levels in the body, ensuring accurate monitoring of therapeutic and toxic concentrations. Choice A is incorrect as drawing blood midway through administration does not provide an accurate peak level. Choice C is incorrect as drawing blood one hour before the next dose does not represent the trough level. Choice D is incorrect because drawing blood immediately after completion of the IV dose does not allow enough time for the drug to reach peak levels.
5. A client with a diagnosis of bipolar disorder is prescribed valproate. The nurse should monitor for which potential adverse effect?
- A. Weight gain
- B. Hair loss
- C. Hyperglycemia
- D. Hypoglycemia
Correct answer: A
Rationale: The correct answer is A: Weight gain. Valproate is known to cause weight gain as a common adverse effect. It is important for the nurse to monitor the client's weight regularly while on this medication to detect and address any changes that may occur.
