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. The healthcare professional is caring for a patient with a new order for an oral laxative. Which is a contraindication in administering an oral laxative?
- A. Cardiac problems
- B. Abdominal pain of unknown origin
- C. Several hemorrhoids
- D. Chronic constipation
Correct answer: B
Rationale: Administering an oral laxative to a patient with abdominal pain of unknown origin is contraindicated because it could be a sign of a more serious underlying condition that needs immediate medical evaluation. Giving a laxative in such a situation without proper diagnosis could potentially worsen the patient's condition or delay appropriate treatment. Choice A (Cardiac problems) is not a contraindication for an oral laxative unless the patient has a specific cardiac condition that interacts with the laxative. Choice C (Several hemorrhoids) and Choice D (Chronic constipation) are not contraindications for administering an oral laxative.
3. A client is taking levodopa-carbidopa for Parkinson's disease. The nurse should include which instruction when educating the client about this medication?
- A. Increase fluid intake to prevent dehydration.
- B. Take medication with food to improve absorption.
- C. Take medication at bedtime to avoid daytime drowsiness.
- D. It can cause nausea and dizziness.
Correct answer: A
Rationale: The correct instruction for a client taking levodopa-carbidopa for Parkinson's disease is to increase fluid intake to prevent dehydration. Levodopa-carbidopa should be taken with food to reduce gastrointestinal upset and improve absorption. Taking medication at bedtime is not necessary to avoid daytime drowsiness. It is crucial to prevent dehydration due to the medication's side effects. Choice B is incorrect because the medication should be taken with food, not at bedtime. Choice C is incorrect as taking the medication with food, rather than on an empty stomach, aids in absorption and reduces gastrointestinal side effects. Choice D is incorrect as it states the side effects of the medication rather than providing specific instructions on its administration.
4. When administering medications to a group of clients, which client should the nurse closely monitor for the development of acute kidney injury (AKI)?
- A. Lorazepam
- B. Sucralfate
- C. Digoxin
- D. Vancomycin
Correct answer: D
Rationale: Vancomycin is known to be nephrotoxic, which means it can cause damage to the kidneys. Therefore, clients receiving Vancomycin should be closely monitored for signs and symptoms of acute kidney injury (AKI) to ensure early detection and intervention if necessary. Lorazepam, Sucralfate, and Digoxin do not typically cause acute kidney injury, so they are not the priority for monitoring in this scenario.
5. Prior to administration of the initial dose of the GI agent misoprostol, which information should the nurse obtain from the client?
- A. Taking an anti-emetic medication
- B. History of glaucoma
- C. Currently pregnant
- D. Allergy to aspirin
Correct answer: C
Rationale: The correct answer is C. It is crucial for the nurse to obtain information regarding the client's pregnancy status before administering misoprostol, as this medication is contraindicated in pregnancy due to its potential to cause uterine contractions. This can lead to serious complications such as miscarriage or premature birth. Therefore, assessing whether the client is currently pregnant is essential to ensure the safe administration of misoprostol. Choices A, B, and D are not directly related to the administration of misoprostol. While knowing if the client is taking an anti-emetic medication may be relevant to prevent drug interactions, a history of glaucoma and allergy to aspirin are not primary concerns before administering misoprostol.
