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 B
Explanation
A. Compare muscle strength bilaterally. While hyperkalemia can lead to muscle weakness, assessing muscle strength bilaterally is not the most critical intervention in this scenario. The priority is to assess for cardiac manifestations of hyperkalemia.
B. Determine apical pulse rate and rhythm. Hyperkalemia can cause life-threatening cardiac dysrhythmias, including bradycardia, heart block, and ventricular tachycardia. Assessing the apical pulse rate and rhythm can provide essential information about cardiac function and help identify potential dysrhythmias.
C. Assess strength of deep tendon reflexes. Hyperkalemia can affect neuromuscular function, leading to hyperreflexia or diminished reflexes. While assessing deep tendon reflexes is
important, it is not as critical as assessing cardiac function in a client with known hyperkalemia.
D. Observe color and amount of urine. While changes in urinary output and characteristics may indicate renal impairment associated with hyperkalemia, the priority in this situation is to assess for cardiac manifestations of hyperkalemia.
Correct Answer is C
Explanation
A. Right ear hearing loss. While significant, right ear hearing loss is not immediately life- threatening.
B. Difficulty with balance. Balance issues may be concerning but are not typically indicative of a life-threatening condition.
C. Intensifying headache. An intensifying headache can be a sign of increased intracranial pressure, which is a medical emergency and requires immediate attention.
D. Facial numbness. Facial numbness can indicate nerve involvement but is not as immediately concerning as an intensifying headache, which could indicate a serious neurological issue such as bleeding or swelling in the brain.
