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 receiving bethanechol chloride (Urecholine). The nurse monitors the client for adverse effects of the medication and should observe for which of the following?
- A. Bradycardia
- B. Constipation
- C. Hypertension
- D. Dry mouth
Correct answer: A
Rationale: Corrected Rationale: Bethanechol chloride (Urecholine) stimulates muscarinic receptors, which can lead to bradycardia as an adverse effect. Monitoring for bradycardia is crucial when administering this medication. Constipation, hypertension, and dry mouth are not typically associated with the effects of bethanechol chloride. Bradycardia is the correct adverse effect to monitor for, making option A the correct answer. Constipation, hypertension, and dry mouth are not commonly seen with bethanechol chloride and are therefore incorrect choices.
3. A client is receiving furosemide (Lasix) and is being discharged. What should the nurse include in the teaching plan?
- A. Consume potassium-rich foods.
- B. Take the medication in the morning.
- C. Change positions slowly to prevent dizziness.
- D. Maintain an adequate fluid intake.
Correct answer: C
Rationale: The correct answer is to instruct the client to change positions slowly to prevent dizziness. Furosemide (Lasix) is a diuretic that can lead to orthostatic hypotension, causing dizziness. Consuming potassium-rich foods is essential to prevent hypokalemia when taking furosemide. Taking the medication in the morning helps reduce the need for frequent urination at night. Encouraging the client to maintain an adequate fluid intake is crucial to prevent dehydration while on this medication.
4. A client is receiving morphine sulfate subcutaneously for pain. Because morphine sulfate has been prescribed for this client, which nursing action would be included in the plan of care?
- A. Encourage fluid intake.
- B. Monitor the client's temperature.
- C. Maintain the client in a supine position.
- D. Encourage the client to cough and deep breathe.
Correct answer: D
Rationale: Morphine sulfate suppresses the cough reflex, which can lead to the retention of secretions in the lungs. Encouraging the client to cough and deep breathe helps prevent pneumonia by clearing the airways of any accumulated secretions. This intervention is crucial in clients receiving morphine sulfate to maintain optimal respiratory function.
5. A client with chronic obstructive pulmonary disease (COPD) is prescribed tiotropium (Spiriva). Which instruction should the nurse include in the teaching plan?
- A. Use the medication as a rescue inhaler.
- B. Rinse your mouth after using the inhaler.
- C. Take the medication on an empty stomach.
- D. Take the medication with a full glass of water.
Correct answer: B
Rationale: Tiotropium (Spiriva) is not a rescue inhaler but a maintenance medication for COPD. The correct instruction for the nurse to include in the teaching plan is to advise the client to rinse their mouth after using the inhaler. This practice helps prevent dry mouth and throat irritation, common side effects of tiotropium. There are no specific recommendations to take tiotropium on an empty stomach or with a full glass of water.
