1. A client receiving enalapril reports a persistent dry cough. The nurse should explain that this side effect is related to which medication action?
- A. It reduces the production of angiotensin II.
- B. It increases the production of angiotensin II.
- C. It causes increased production of bradykinin.
- D. It increases the production of aldosterone.
Correct answer: C
Rationale: The correct answer is C. Enalapril, an ACE inhibitor, inhibits the conversion of angiotensin I to angiotensin II, leading to increased levels of bradykinin. The accumulation of bradykinin is responsible for the persistent dry cough associated with ACE inhibitors like enalapril. Choices A, B, and D are incorrect because enalapril does not directly affect the production of angiotensin II or aldosterone. Instead, it primarily impacts the renin-angiotensin-aldosterone system by inhibiting the conversion of angiotensin I to angiotensin II, leading to bradykinin accumulation.
2. The client enters the room of a client with Parkinson’s disease who is taking carbidopa-levodopa. The client is arising slowly from the chair while the unlicensed assistive personnel (UAP) stands next to the chair. What action should the nurse take?
- A. Demonstrate how to help the client move more efficiently
- B. Offer a PRN analgesic to reduce painful movement
- C. Affirm that the client should arise slowly from the chair
- D. Tell the UAP to assist the client in moving more quickly
Correct answer: A
Rationale: The correct action for the nurse to take in this situation is to demonstrate how to help the client move more efficiently. As the client is arising slowly from the chair, providing guidance on proper movement techniques can improve the client's mobility and safety. Offering a PRN analgesic (Choice B) is not relevant to the client's situation as there is no indication of pain. Affirming that the client should arise slowly (Choice C) does not address the need for assistance in improving movement efficiency. Instructing the UAP to assist the client in moving more quickly (Choice D) may compromise the client's safety and is not the appropriate action to take.
3. The patient refuses a morning bath, stating a preference for evening baths. What is the best action for the nurse to take?
- A. Defer the bath until evening and pass on the information to the next shift.
- B. Tell the patient that daily morning baths are the 'normal' routine.
- C. Explain the importance of maintaining morning hygiene practices.
- D. Cancel hygiene for the day and attempt again in the morning.
Correct answer: A
Rationale: The best action for the nurse is to respect the patient's preference and autonomy. By deferring the bath until evening, the nurse acknowledges and accommodates the patient's routine, promoting patient-centered care. Choice B could be seen as dismissive of the patient's preference and may not foster a therapeutic relationship. Choice C, while important, doesn't address the patient's current refusal. Choice D is not respectful of the patient's autonomy and could lead to increased resistance. Therefore, option A is the most appropriate and patient-centered approach.
4. A client with chronic kidney disease is being evaluated for dialysis. Which laboratory value would be most concerning to the nurse?
- A. Hemoglobin 9.5 g/dL
- B. Potassium 6.2 mEq/L
- C. Creatinine 3.5 mg/dL
- D. BUN 50 mg/dL
Correct answer: B
Rationale: The correct answer is B: Potassium 6.2 mEq/L. In chronic kidney disease, the kidneys struggle to regulate potassium levels, leading to hyperkalemia. A potassium level of 6.2 mEq/L is dangerously high and can cause life-threatening cardiac arrhythmias. Hemoglobin of 9.5 g/dL may indicate anemia, which is common in chronic kidney disease but is not immediately life-threatening. Creatinine and BUN levels are markers of kidney function; although elevated levels indicate kidney impairment, they are not acutely life-threatening like severe hyperkalemia.
5. A client with a diagnosis of generalized anxiety disorder is prescribed lorazepam. The client should be informed that this medication may have which potential side effect?
- A. Drowsiness
- B. Dry mouth
- C. Nausea
- D. Headache
Correct answer: A
Rationale: The correct answer is A: Drowsiness. Lorazepam, a medication commonly used to treat anxiety disorders, can lead to drowsiness as a common side effect. It is important for clients to be aware of this potential effect, and they should be advised to avoid activities like driving until they understand how the medication affects them. Dry mouth, nausea, and headache are possible side effects of other medications but are less commonly associated with lorazepam.
