The nurse plans to collect a 24 hour urine specimen for a creatinine clearance test. Which instruction should the nurse provide to the adult male client?
Urinate at a specified time, discard this urine, and collect all subsequent urine during the next 24 hours.
Urinate immediately into a urinal, and the lab will collect the specimen every 6 hours, for the next 24 hours.
For the next 24 hours, notify nurse when the bladder is full, and the nurse will collect catheterized specimens.
Cleanse around the meatus, discard first portion of voiding, and collect the rest in a sterile bottle.
The Correct Answer is A
A. Urinate at a specified time, discard this urine, and collect all subsequent urine during the next 24 hours: Discarding the first void ensures the collection begins with an empty bladder, and all urine afterward is included for accurate measurement.
B. Urinate immediately into a urinal, and the lab will collect the specimen every 6 hours, for the next 24 hours: This describes timed urine sampling, not a continuous 24-hour collection required for creatinine clearance.
C. For the next 24 hours, notify nurse when the bladder is full, and the nurse will collect catheterized specimens: Routine creatinine clearance testing does not require catheterization unless the client is already catheterized.
D. Cleanse around the meatus, discard first portion of voiding, and collect the rest in a sterile bottle: This describes a midstream or clean-catch technique, typically used for urine cultures, not 24-hour collections.

Correct Answer is C
Explanation
A. Instruct the client to cough as the suction tip is removed: Coughing can help clear secretions, but this action is not the primary safety concern during suctioning. The priority is minimizing the risk of injury, infection, and contamination during the procedure
B. Instil 3 mL of 0.9% sodium chloride before suctioning: Instilling saline before suctioning is generally not recommended as it can lead to complications, such as increasing mucus production, which can make suctioning more difficult.
C. Wear protective goggles while performing the procedure: Suctioning a tracheostomy can involve secretions that may potentially splash, so it’s important to wear protective goggles, as well as other appropriate personal protective equipment, to ensure safety and prevent contamination.
D. Apply a water-soluble lubricant to the catheter: Applying lubricant to the catheter is not recommended. The suction catheter should be kept sterile and dry to avoid introducing any contaminants into the trachea or the airway.
Correct Answer is ["5.6"]
Explanation
Rationale:
- Convert the client's weight from pounds (lb) to kilograms (kg).
Weight in kg = 132 lb / 2.2 lb/kg
= 60 kg.
- Calculate the desired dose per minute in micrograms (mcg).
Desired dose per minute (mcg/min) = Desired dose (mcg/kg/min) × Weight (kg)
= 5 mcg/kg/min × 60 kg
= 300 mcg/min.
- Convert the desired dose from micrograms per minute (mcg/min) to milligrams per hour (mg/hr).
1 mg = 1000 mcg
1 hr = 60 min
Desired dose in mg/hr = (300 mcg/min / 1000 mcg/mg) × 60 min/hr
= 0.3 mg/min × 60 min/hr
= 18 mg/hr.
- Determine the concentration of the available Dopamine solution in milligrams per milliliter (mg/mL).
Available concentration = Total medication (mg) / Total volume (mL)
= 1600 mg / 500 mL
= 3.2 mg/mL.
- Calculate the IV pump rate in milliliters per hour (mL/hr).
IV pump rate (mL/hr) = Desired dose (mg/hr) / Available concentration (mg/mL)
= 18 mg/hr / 3.2 mg/mL
= 5.625 mL/hr.
- Round the answer to the nearest tenth.
= 5.6
