A nurse is preparing to administer amantadine 150 mg PO every 12 hours. Available is amantadine 50 mg/5 mL syrup. How many mL should the nurse administer per dose?

(Round the answer to the nearest whole number. Use a leading zero if it applies. Do not use a trailing zero.)

The correct answer is choice C: "You will need to avoid rigorous exercise during the test."

Rationale:

• Choice A: The collection time for a 24-hour urine creatinine clearance test typically starts at a specific time, not necessarily with the first urine of the day.
• Choice B: A creatinine clearance test requires a 24-hour urine collection, not just 12 hours.
• Choice C: Avoiding rigorous exercise is important during the test as it can affect creatinine levels and impact the accuracy of the results.
• Choice D: Storing the urine container in a dark location is not necessary for a creatinine clearance test.

Choice A reason: Decreasing the IV fluid infusion rate and limiting oral fluid intake may not be appropriate without further assessment, as the client's BUN level is elevated, which could indicate dehydration or renal impairment. The normal range for BUN is typically 7-20 mg/dL.

Choice B reason: Collecting a urine specimen for culture and sensitivity may be necessary if there is a suspicion of infection, but there is no indication of infection based solely on the provided lab values.

Choice C reason: Evaluating urine for amount and specific gravity can help assess the client's hydration status and kidney function, which is pertinent given the elevated BUN level and ongoing nausea and vomiting.

Choice D reason: Continuing routine care may not be appropriate because the BUN level is above the normal range, indicating that further assessment and intervention may be necessary.
