A nurse is collecting a specimen for urinalysis and culture from a client who has an indwelling urinary catheter. Which of the following actions should the nurse take during collection?
Clamp the catheter distal to the injection port.
Drain the specimen from the drainage bag.
Collect 2 mL of urine for each specimen.
Obtain the urinalysis specimen before the culture specimen.
The Correct Answer is A
Rationale:
A. Clamp the catheter distal to the injection port: Clamping the catheter allows urine to accumulate in the tubing, ensuring a fresh specimen can be obtained from the sampling port rather than from stagnant urine in the drainage bag, which could be contaminated.
B. Drain the specimen from the drainage bag: Urine in the drainage bag may be old and contaminated, which can lead to inaccurate culture results. Specimens should be collected aseptically from the catheter sampling port.
C. Collect 2 mL of urine for each specimen: For accurate urinalysis and culture, a larger volume typically 3–10 mL for culture and 10–15 mL for routine urinalysis is recommended to ensure enough specimen for testing and repeat analysis if needed.
D. Obtain the urinalysis specimen before the culture specimen: Culture specimens should be collected first to prevent contamination. Performing urinalysis first can alter the bacterial composition of the sample and compromise culture accuracy.

Correct Answer is B
Explanation
A. Prospective audit: A prospective audit evaluates care before it is provided, focusing on planned interventions rather than outcomes after discharge. It is not used to assess post-care quality.
B. Outcome audit: Outcome audits measure the results of care, such as client recovery, complication rates, or satisfaction, after interventions have been completed. This type of audit is appropriate for gathering information about quality of care following discharge.
C. Structure audit: Structure audits assess the resources, staffing, and organizational infrastructure used to deliver care. They do not measure client outcomes or post-discharge quality.
D. Concurrent audit: Concurrent audits evaluate care while it is being provided, allowing immediate feedback and corrections. They are performed during hospitalization, not after discharge.
Correct Answer is ["2.5"]
Explanation
Calculation:
Desired dose = 20 mg.
Available concentration = 40 mg / 5 mL
= 8 mg/mL.
- Calculate the volume to administer in milliliters (mL).
Volume to administer (mL) = Desired dose (mg) / Available concentration (mg/mL)
= 20 mg / 8 mg/mL
= 2.5 mL.
