Question 1 of 5
A nurse is caring for a client who has a new prescription for metformin. Which of the following laboratory results should the nurse evaluate prior to administering the first dose?
Correct Answer: B
Rationale: The correct answer is B: Creatinine level. Metformin is excreted by the kidneys, so assessing the client's creatinine level is crucial to determine kidney function. Elevated creatinine levels may indicate impaired renal function and increase the risk of metformin accumulation, leading to potential toxicity. Evaluating potassium levels (choice
A) is important for other medications but not specifically for metformin. Platelet count (choice
C) and liver enzymes (choice
D) are not directly related to metformin administration.
