Correct Answer: B

Rationale: Corrected Rationale: Omeprazole can cause hypomagnesemia, a condition characterized by low magnesium levels in the blood. Monitoring magnesium levels is crucial to detect and address this potential adverse effect. Liver function (Choice A) is not typically affected by omeprazole. Blood glucose (Choice C) and hemoglobin levels (Choice D) are not directly impacted by omeprazole administration. Therefore, magnesium levels (Choice B) are the most appropriate parameter to monitor in a client prescribed omeprazole.

Correct Answer: B

Rationale: The correct answer is B: 'Monitor for dyskinesia.' Levodopa-carbidopa can cause dyskinesia as a side effect, which is characterized by involuntary muscle movements. Patients need to be monitored for this adverse effect and instructed to report it to their healthcare provider. Choices A, C, and D are incorrect because levodopa-carbidopa is not a cure for Parkinson's disease, it should be taken at specific times for optimal effect, and it does have side effects, such as dyskinesia.

Correct Answer: B

Rationale: The correct answer is B: Serum creatinine. Vancomycin is known to be nephrotoxic, meaning it can cause kidney damage. Monitoring serum creatinine levels is essential to assess kidney function and detect any signs of nephrotoxicity. Blood glucose levels (choice A) are not directly affected by vancomycin. INR levels (choice C) are typically monitored for clients on anticoagulants, not vancomycin. Liver function tests (choice D) are not primarily affected by vancomycin use; kidney function is of greater concern.

Correct Answer: B

Rationale: The correct answer is to monitor blood glucose levels before administration. This step is crucial to ensure the correct dose of insulin is administered based on the current blood glucose level. Choice A is incorrect as insulin usually needs to be stored in the refrigerator and has an expiration date. Choice C is incorrect because insulin can be short-acting, rapid-acting, intermediate-acting, or long-acting. Choice D is also incorrect as insulin can have side effects such as hypoglycemia if the dose is too high.

Correct Answer: D

Rationale: The correct answer is D. Roast turkey is a lean protein option suitable for a low-fat diet. Rice pilaf and green beans are also low in fat. Choices A, B, and C contain high-fat ingredients like gravy, cheese, cream, and ice cream, which are not suitable for a low-fat diet.
