A home health nurse is reinforcing teaching about home safety with an older adult client who lives alone. Which of the following client statements indicates an understanding of the teaching?

A. "Sit back down for a few minutes when this occurs.": This is correct. Lightheadedness upon standing is a common side effect of ACE inhibitors due to their blood pressure-lowering effect. The client should be advised to sit down to prevent falls and allow the body to adjust.

B. "Take a daily potassium supplement.": This is incorrect. ACE inhibitors can increase potassium levels, and taking a potassium supplement without a healthcare provider’s recommendation may lead to hyperkalemia, a dangerous condition.

C. "Restrict your daily fluid intake.": This is incorrect. Dehydration can exacerbate hypotension, so it is not recommended to restrict fluid intake without further instructions from the provider.

D. "Discontinue this medication if this occurs again.": This is incorrect. The client should not discontinue medication without first consulting their healthcare provider. The healthcare provider may adjust the dosage or provide alternative recommendations to manage the side effects.

A. BUN 18 mg/dL is incorrect. A BUN (blood urea nitrogen) level of 18 mg/dL is within the normal range (typically 7–20 mg/dL) and does not indicate immediate concern in this context. An elevated BUN could indicate dehydration, but this level is not significantly elevated.

B. Serum creatinine 1.0 mg/dL is incorrect. Serum creatinine levels are also within normal limits for most adults, which is around 0.6–1.2 mg/dL, and this finding does not indicate a problem.

C. Urine output 12 mL/hr is correct. A urine output of 12 mL/hr is low and indicates oliguria, which is a concern in the context of dehydration. The normal urine output for an adult is at least 30 mL/hr. A decrease in urine output suggests that the kidneys are not receiving adequate blood flow, which could indicate severe dehydration and requires immediate attention from the provider.

D. Urine specific gravity 1.020 is incorrect. Urine specific gravity of 1.020 is within the normal range (typically 1.005–1.030) and indicates that the kidneys are concentrating urine appropriately, which is not a concerning finding in this case.
