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 ["A","B","D","G"]
Explanation
Rationale for Correct Answers:
- Uterus firm at 1 cm above the umbilicus and tender to palpation: Normally, by postpartum day 3, the uterus should be well below the umbilicus. A uterus that is still above and tender suggests endometritis or subinvolution, especially when combined with foul-smelling lochia.
- Moderate amount of dark brown, foul-smelling lochia noted: Lochia should progress from rubra (day 1–3, red) → serosa (day 4–10, pink/brown) → alba (day 10 onward, white/yellow). Foul-smelling lochia is a hallmark of uterine infection (endometritis).
- Temperature 38.2° C (100.8° F): A postpartum fever ≥38°C on two occasions, or even once when associated with uterine tenderness and foul lochia, is significant and indicates infection.
- WBC count 33,000/mm³: Although WBCs can be physiologically elevated postpartum (up to 20,000–25,000), a count this high is abnormal and strongly suggests severe infection.
Rationale for Incorrect Answers:
- Surgical incision well approximated with slight edema present: Mild edema is expected in the early healing process; no erythema, drainage, or dehiscence is noted, so no immediate concern.
- Respiratory rate 18/min: This is within normal range (12–20/min), no evidence of respiratory compromise.
SaO₂ 97% on room air: This is normal oxygen saturation, not concerning
Correct Answer is B,D,C,A
Explanation
Rationale:
B. Place the child in a sitting position: Positioning the child upright or with the head slightly tilted back promotes comfort, stability, and proper visualization of the conjunctival sac for accurate drop placement.
D. Pull the lower eyelid downward: This creates a conjunctival pocket that holds the medication and allows it to spread evenly over the eye surface without spilling.
C. Instill the drops of medication: Instillation should occur after exposing the conjunctival sac to ensure the medication reaches the target area. The dropper should not touch the eye to prevent contamination.
A. Apply pressure to the lacrimal punctum: This step is performed last to prevent systemic absorption of the medication by blocking the nasolacrimal duct. Holding gentle pressure for about 1 minute helps maximize the local effect of the drops.
