Pharmacology HESI 55 Questions 2023
1. A male client receives a scopolamine transdermal patch 2 hours before surgery. Four hours after surgery, the client tells the nurse that he is experiencing pain and asks why the patch is not working. Which action should the nurse take?
- A. Advise the client that the effects of the medication have worn off
- B. Explain that the medication is not given to relieve pain
- C. Check for the correct placement of the patch on the client
- D. Offer to apply a new transdermal patch to address the pain
Correct answer: B
Rationale: The correct answer is B. Scopolamine is not a pain medication; it is commonly used to prevent nausea and vomiting, particularly in surgical settings. It works on the central nervous system to help control these symptoms, not to relieve pain. Therefore, it is important for the nurse to explain to the client that the medication is not intended to relieve pain but rather to manage other specific symptoms. Checking the correct placement of the patch is also important to ensure proper administration, but addressing the misconception about the medication's purpose is the priority in this scenario. Offering to apply a new patch would not address the client's pain as scopolamine is not meant for pain relief. Advising the client that the effects have worn off is inaccurate because the medication is not used for pain management.
2. A client with a diagnosis of bipolar disorder is prescribed carbamazepine. The nurse should monitor for which potential adverse effect?
- A. Agranulocytosis
- B. Hair loss
- C. Liver toxicity
- D. Weight gain
Correct answer: A
Rationale: Carbamazepine is associated with the potential adverse effect of agranulocytosis, a serious condition characterized by a low white blood cell count. Monitoring white blood cell counts regularly is crucial to detect this adverse effect early and prevent complications.
3. A client with diabetes mellitus type 2 is prescribed linagliptin. Which instruction should the nurse include in the client's teaching plan?
- A. Report any signs of pancreatitis to the healthcare provider.
- B. Take this medication with meals.
- C. Avoid alcohol while taking this medication.
- D. Report any signs of heart failure to the healthcare provider.
Correct answer: A
Rationale: When a client is prescribed linagliptin, it is crucial to educate them to report any signs of pancreatitis to their healthcare provider. Linagliptin can lead to pancreatitis, making it essential for clients to be vigilant for symptoms such as severe abdominal pain, nausea, and vomiting. Timely reporting of these symptoms can aid in early intervention and management of pancreatitis.
4. A client with a history of heart failure is prescribed carvedilol. The nurse should monitor for which potential side effect?
- A. Bradycardia
- B. Tachycardia
- C. Hypertension
- D. Hyperglycemia
Correct answer: A
Rationale: When a client is prescribed carvedilol, the nurse should monitor for bradycardia, a potential side effect of this medication. Carvedilol is a beta-blocker that can slow down the heart rate, so monitoring for signs of bradycardia is essential to prevent any adverse effects on the client's cardiovascular system. Tachycardia (Choice B) is less likely to occur with carvedilol since it primarily works to reduce heart rate. Hypertension (Choice C) and hyperglycemia (Choice D) are not common side effects associated with carvedilol.
5. A client with a diagnosis of depression is prescribed escitalopram. Which statement by the client indicates the need for further teaching?
- A. I should take this medication in the morning with food.
- B. This medication may take 1 to 4 weeks to notice improvement in symptoms.
- C. I can stop taking this medication once I feel better.
- D. This medication might make me feel drowsy.
Correct answer: C
Rationale: It is crucial for clients to understand that they should not discontinue escitalopram abruptly, even if they start feeling better. Stopping the medication suddenly can lead to withdrawal symptoms or a relapse of depression. It is essential to complete the full course of treatment as prescribed by the healthcare provider to ensure the best outcomes and prevent potential complications.
