HESI Pharmacology Practice Exam
1. A client receives a prescription for methocarbamol (Robaxin), and the nurse reinforces instructions to the client regarding the medication. Which client statement would indicate a need for further instructions?
- A. My urine may turn brown or green.
- B. This medication is prescribed to help relieve my muscle spasms.
- C. If my vision becomes blurred, I need to be concerned about it.
- D. I need to call my doctor if I experience nasal congestion from this medication.
Correct answer: C
Rationale: The correct answer is C because blurred vision is an adverse effect of methocarbamol (Robaxin) and should be reported to a healthcare provider. Choices A, B, and D are all correct statements. Option A informs the client about a possible discoloration of urine, which is a known side effect. Option B correctly explains the purpose of the medication. Option D correctly advises the client to contact their doctor if they experience nasal congestion, which could indicate an adverse reaction.
2. A client has begun therapy with theophylline (Theo-24). The nurse tells the client to limit the intake of which of the following while taking this medication?
- A. Oranges and pineapple
- B. Coffee, cola, and chocolate
- C. Oysters, lobster, and shrimp
- D. Cottage cheese, cream cheese, and dairy creamers
Correct answer: B
Rationale: Theophylline is a xanthine bronchodilator. Xanthines are found in coffee, cola, and chocolate. These foods should be limited while taking theophylline to prevent potential drug interactions or adverse effects.
3. A client is receiving morphine sulfate for pain management. Which assessment finding requires immediate action?
- A. Constipation
- B. Drowsiness
- C. Respiratory rate of 10 breaths per minute
- D. Nausea
Correct answer: C
Rationale: A respiratory rate of 10 breaths per minute indicates respiratory depression, a serious side effect of morphine sulfate that can lead to respiratory compromise and requires immediate intervention. Constipation, drowsiness, and nausea are common side effects of morphine but are not immediately life-threatening compared to respiratory depression. Monitoring and addressing a low respiratory rate are crucial in preventing further respiratory distress or failure.
4. A client with rheumatoid arthritis is prescribed methotrexate. Which instruction should the nurse include in the client's teaching plan?
- A. Avoid taking folic acid supplements.
- B. Report any signs of infection immediately.
- C. Take the medication with a full meal.
- D. Limit fluid intake while on this medication.
Correct answer: B
Rationale: The correct instruction for the nurse to include in the client's teaching plan when taking methotrexate is to report any signs of infection immediately. Methotrexate can suppress the immune system, making the client more susceptible to infections. It is important for the client to promptly report any signs of infection to receive timely medical intervention. Choice A is incorrect because folic acid supplements are often recommended to reduce side effects of methotrexate. Choice C is incorrect as methotrexate is usually taken on an empty stomach unless the client experiences gastrointestinal upset. Choice D is incorrect as there is no need to limit fluid intake while on methotrexate; in fact, maintaining adequate fluid intake is important to prevent complications such as kidney damage.
5. Before administering Methylergonovine (Methergine) to a client with postpartum hemorrhage caused by uterine atony, the nurse checks which of the following as the important client parameter?
- A. Temperature
- B. Lochial flow
- C. Urine output
- D. Blood pressure
Correct answer: D
Rationale: Methylergonovine (Methergine) acts by stimulating uterine contractions and causing vasoconstriction. As vasoconstriction can potentially impact blood pressure, it is crucial to check the client's blood pressure before administering Methylergonovine to monitor for any hypertensive effects.
