1. The practical nurse administered carbidopa-levodopa to a client diagnosed with Parkinson's disease. Which outcome by the client would indicate a therapeutic response?
- A. Decreased blood pressure
- B. Lessening of tremors
- C. Increased salivation
- D. Increased attention span
Correct answer: B
Rationale: The correct answer is B: Lessening of tremors. Carbidopa-levodopa increases the amount of levodopa to the CNS, providing more dopamine to the brain. Increased dopamine levels help alleviate Parkinson's symptoms such as tremors, involuntary movements, and gait abnormalities. Choices A, C, and D are incorrect as carbidopa-levodopa is not expected to have a direct effect on blood pressure, salivation, or attention span in the context of treating Parkinson's disease.
2. A client with hypertension is prescribed lisinopril. The nurse should monitor for which potential side effect?
- A. Dry cough
- B. Hyperkalemia
- C. Hypernatremia
- D. Hyponatremia
Correct answer: A
Rationale: The correct answer is A: Dry cough. Lisinopril, an ACE inhibitor, is known to cause a persistent dry cough as a common side effect. Monitoring for this adverse effect is crucial because it may lead to non-adherence to the medication. Hyperkalemia (choice B) is a potential side effect of potassium-sparing diuretics, not ACE inhibitors like lisinopril. Hypernatremia (choice C) refers to elevated sodium levels and is not a common side effect of lisinopril. Hyponatremia (choice D) is a condition characterized by low sodium levels and is not a typical side effect of lisinopril. Therefore, the nurse should focus on assessing the client for a dry cough when taking lisinopril.
3. A client with diabetes mellitus type 1 is prescribed insulin glargine. When should the nurse instruct the client to administer this medication?
- A. Before meals
- B. After meals
- C. At bedtime
- D. In the morning
Correct answer: C
Rationale: Corrected Rationale: Insulin glargine is a long-acting insulin that provides a consistent level of insulin over 24 hours. Administering it at bedtime helps mimic the body's natural insulin secretion pattern and provides optimal blood glucose control during the night and throughout the day. Choice A (Before meals) is incorrect because insulin glargine is not a rapid-acting insulin meant to cover meals. Choice B (After meals) is incorrect as the timing doesn't align with the insulin's mechanism. Choice D (In the morning) is incorrect as administering insulin glargine in the morning may not provide adequate coverage throughout the night and the following day.
4. A client with a diagnosis of generalized anxiety disorder is prescribed buspirone. The nurse should include which instruction in the client's teaching plan?
- A. This medication may cause drowsiness; avoid driving.
- B. This medication may take several weeks to take effect.
- C. This medication can be taken on an as-needed basis.
- D. This medication should be taken with food.
Correct answer: B
Rationale: Buspirone may take several weeks to take effect, so clients should continue taking it as prescribed and not expect immediate relief.
5. How does omeprazole work in treating a peptic ulcer?
- A. Increasing the production of gastric acid
- B. Neutralizing stomach acid
- C. Coating the stomach lining
- D. Reducing gastric acid secretion
Correct answer: D
Rationale: Omeprazole is a proton pump inhibitor that works by reducing gastric acid secretion. By inhibiting the enzyme responsible for pumping acid into the stomach, omeprazole helps decrease the acidity level in the stomach, providing relief from peptic ulcers. Option A is incorrect because omeprazole does not increase gastric acid production; instead, it decreases it. Option B is incorrect as omeprazole does not neutralize existing stomach acid but rather reduces its secretion. Option C is incorrect as omeprazole does not coat the stomach lining but acts on reducing acid secretion.
