The nurse plans to collect a 24-hour urine specimen for a creatinine clearance test. Which instruction should the nurse provide to the CLIENT?
For the next 24 hours, notify the nurse when the bladder is full, and the nurse will collect catheterized specimens.
Urinate immediately into a urinal, and the lab will collect the specimen every 6 hours for the next 24 hours.
Urinate at a specified time, discard this urine, and collect all subsequent urine during the next 24 hours.
Cleanse and meatus, discard the first portion of voiding, and collect the rest in a sterile bottle.
The Correct Answer is C
A. This instruction is incorrect because it suggests collecting catheterized specimens, which is not necessary for a creatinine clearance test. Catheterization may increase the risk of contamination and is not typically performed for this test.
B. This instruction is incorrect because it does not involve the collection of a complete 24-hour urine specimen. Collecting specimens every 6 hours would not provide an accurate measurement of creatinine clearance over a 24-hour period.
C. This instruction is correct. For a 24-hour urine collection, the client should urinate at a specified time to start the collection period, discard this urine, and then collect all subsequent urine produced over the next 24 hours. This ensures that the entire 24-hour period is captured for analysis.
D. This instruction is incorrect because it does not involve the collection of all urine produced over a 24-hour period. Additionally, discarding the first portion of voiding is not necessary for a creatinine clearance test and may lead to inaccurate results.

Correct Answer is A
Explanation
A. Every 5 minutes for 30 minutes is crucial after paracentesis to closely monitor for signs of hypovolemia, such as a sudden drop in blood pressure. After this initial intensive monitoring period, the frequency can be reduced to every 4 hours to assess for any delayed effects or complications.
B. Every 5 minutes for one hour is a shorter duration of monitoring compared to option A and
may not provide adequate time to detect and respond to any significant changes in blood pressure that could occur after paracentesis, especially considering the volume of fluid removed.
C. Every 15 minutes for one hour, then every 1 hour for 2 hours provides frequent monitoring
initially, but the interval between assessments is too long after the first hour, potentially missing early signs of complications such as hypovolemia.
D. Every 1 hour for 2 hours does not provide sufficient frequency of monitoring, especially during the critical immediate post-paracentesis period when rapid changes in blood pressure can occur. This schedule may delay the detection and management of complications.
Correct Answer is A
Explanation
A. Measure urinary output every hour. Dopamine is commonly used to improve blood pressure and renal perfusion in hypotensive clients. Monitoring urinary output is crucial because dopamine can increase renal blood flow and urine output. Hourly measurement allows for early detection of changes in renal function and urine output, enabling prompt intervention if needed.
B. Initiate seizure precautions. Seizures are not a common adverse effect of dopamine administration. Therefore, initiating seizure precautions is unnecessary in this context.
C. Assess pupillary response to light hourly. While assessing pupillary response is important in neurological assessments, it is not a priority intervention specifically related to dopamine
administration for hypotension.
D. Monitor serum potassium frequently. Dopamine administration is not directly associated with alterations in serum potassium levels. While electrolyte monitoring is important in some
situations, it is not the primary concern when administering dopamine for hypotension. Monitoring urinary output is more pertinent in this scenario.
