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 with chronic pain is prescribed transdermal fentanyl (Duragesic) patches. Which instruction should the nurse include in the teaching plan?
- A. Apply the patch to a different site each time.
- B. Avoid using heating pads over the patch.
- C. Change the patch every 72 hours.
- D. Remove the old patch before applying the new one.
Correct answer: B
Rationale: Clients using transdermal fentanyl (Duragesic) patches should avoid using heating pads over the patch as heat can increase the release of the medication, potentially leading to overdose. The patch should be applied to a different site each time, changed every 72 hours, and the old patch should be removed before applying a new one to prevent accidental overdose or excessive drug absorption.
3. A community health nurse visits a client at home. Prednisone 10 mg orally daily has been prescribed for the client. The nurse reinforces teaching for the client about the medication. Which statement, if made by the client, indicates that further teaching is necessary?
- A. I can take aspirin or my antihistamine if I need it.
- B. I need to take the medication every day at the same time.
- C. I need to avoid coffee, tea, cola, and chocolate in my diet.
- D. If I gain more than 5 pounds a week, I will call my doctor.
Correct answer: A
Rationale: Aspirin and other over-the-counter medications should not be taken without consulting the health care provider (HCP). The client needs to take the medication at the same time every day and avoid caffeine-containing foods and fluids to prevent steroid-ulcer development.
4. Alendronate (Fosamax) is prescribed for a client with osteoporosis. The client taking this medication is instructed to:
- A. Take the medication at bedtime.
- B. Take the medication in the morning with breakfast.
- C. Lie down for 30 minutes after taking the medication.
- D. Take the medication with a full glass of water after rising in the morning.
Correct answer: D
Rationale: Alendronate (Fosamax) should be taken with a full glass of water after rising in the morning to prevent gastrointestinal side effects and increase absorption. Taking the medication with a full glass of water and in an upright position after waking up helps decrease the risk of esophageal irritation and enhances the drug's effectiveness by ensuring proper absorption in the gastrointestinal tract.
5. A client with hyperlipidemia is prescribed simvastatin (Zocor). Which instruction should the nurse include in the teaching plan?
- A. Take the medication in the evening.
- B. Report any muscle pain to your healthcare provider.
- C. Avoid increasing your intake of grapefruit juice.
- D. Do not take the medication with a high-fat meal.
Correct answer: B
Rationale: Muscle pain can be a sign of a serious side effect of simvastatin (Zocor) known as rhabdomyolysis and should be reported to the healthcare provider immediately. The medication is usually taken in the evening to coincide with the body's natural production of cholesterol. Grapefruit juice should be avoided as it can increase the risk of toxicity by affecting the metabolism of the medication. Additionally, taking simvastatin with a high-fat meal can reduce its effectiveness, so it should be taken without food or with a light meal.
