HESI Pharmacology Practice Exam
1. A client is receiving meperidine (Demerol) 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 severe side effect of meperidine (Demerol) that necessitates immediate intervention to prevent further complications. Constipation, drowsiness, and nausea are common but less urgent side effects that do not pose an immediate life-threatening risk. Respiratory depression can lead to respiratory arrest and must be addressed promptly to ensure the client's safety and well-being.
2. A client is taking phenytoin (Dilantin) for seizure control, and a sample for a serum drug level is drawn. Which of the following indicates a therapeutic serum drug range?
- A. 5 to 10 mcg/mL
- B. 10 to 20 mcg/mL
- C. 20 to 30 mcg/mL
- D. 30 to 40 mcg/mL
Correct answer: B
Rationale: The correct therapeutic serum drug level range for phenytoin (Dilantin) is 10 to 20 mcg/mL. This range is considered optimal for seizure control while minimizing the risk of toxicity. Monitoring drug levels helps ensure that the client is within the therapeutic range for effective treatment.
3. The camp nurse asks the children preparing to swim in the lake if they have applied sunscreen. The nurse reminds the children that chemical sunscreens are most effective when applied:
- A. Immediately before swimming
- B. 15 minutes before exposure to the sun
- C. Immediately before exposure to the sun
- D. At least 30 minutes before exposure to the sun
Correct answer: D
Rationale: Chemical sunscreens are most effective when applied at least 30 minutes before exposure to the sun to allow them to penetrate the skin and provide optimal protection. Applying sunscreen immediately before swimming (Choice A) or immediately before exposure to the sun (Choice C) may not provide sufficient time for the sunscreen to be absorbed and offer proper protection. Applying sunscreen 15 minutes before sun exposure (Choice B) is also not ideal as it may not allow enough time for the sunscreen to work effectively. Therefore, the correct answer is to apply chemical sunscreen at least 30 minutes before exposure to the sun to ensure it can be absorbed and offer the intended protection. It is important to reapply sunscreen after swimming or sweating to maintain its effectiveness.
4. Rifabutin (Mycobutin) is prescribed for a client with active Mycobacterium avium complex (MAC) disease and tuberculosis. The nurse monitors for which side effects of the medication? Select one that doesn't apply.
- A. Signs of hepatitis
- B. Flu-like syndrome
- C. Low neutrophil count
- D. Vitamin B6 deficiency
Correct answer: D
Rationale: Rifabutin is known to cause side effects such as hepatitis, flu-like syndrome, low neutrophil count, and ocular pain or blurred vision. Vitamin B6 deficiency is not associated with rifabutin but is a side effect of isoniazid (INH). Therefore, the nurse should not monitor for Vitamin B6 deficiency when administering rifabutin.
5. 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.
