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 ["0.2"]
Explanation
Step-by-step Calculation:
- We need to find the volume (in mL) of teriparatide that contains the desired dose of 60 mcg.
- Set up the proportion:dose (mcg) / concentration (mcg/mL) = volume (mL)
- Fill in the known values:
- Dose (mcg): 60 mcg (as given in the problem)
- Concentration (mcg/mL): 750 mcg/2.4 mL (from the medication label)
- Solve for the volume:
- Multiply both sides of the proportion by the concentration to isolate the volume on the left:
- dose (mcg) = volume (mL) concentration (mcg/mL)
- Substitute the known values:
- 60 mcg = volume (mL) (750 mcg / 2.4 mL)
- Calculate the volume:
-
- Divide both sides by the concentration to solve for the volume:
- volume (mL) = 60 mcg / (750 mcg / 2.4 mL)
- Simplify:
- volume (mL) = (60 mcg 2.4 mL) / 750 mcg
- volume (mL) = 0.192 mL (approximately)
- Rounding (optional): The problem specifies rounding to the nearest tenth. Since 0.192 is closer to 0.2 than 0.1, the rounded volume is:
- volume (mL) = 0.2 mL (rounded to one decimal place)
Therefore, the nurse should administer 0.2 mL of teriparatide.
Correct Answer is C
Explanation
A. Cover client with cooling blanket.
This could help manage the fever but is not the highest priority in the context of acute adrenal crisis.
B. Obtain an analgesic prescription.
Pain management is important, but it is not the immediate priority in a life-threatening adrenal crisis.
C. Infuse an intravenous fluid bolus.
This is the correct answer because the client is experiencing hypotension (low blood pressure), which is critical in an acute adrenal crisis. IV fluids are essential to restore blood pressure and perfusion.
D. Administer PRN oral antipyretic.
Managing the fever is important, but not the first priority. The client’s hemodynamic instability needs to be addressed immediately.
