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 D
Explanation
Rationale:
A. Place the head of the client's bed flat with the client's legs extended: Positioning flat may increase tension on the abdominal incision, potentially worsening the dehiscence. A low Fowler’s position with knees slightly bent is preferred to reduce strain on the wound.
B. Apply butterfly strips to approximate the wound edges: Forcing the wound edges together could trap bacteria inside and increase the risk of infection. Dehiscence requires moist protection, not forced closure at the bedside.
C. Apply pressure directly to the wound for 15 min: Direct pressure is appropriate for active bleeding, not for dehiscence. Applying pressure could damage tissues further and does not address the need to protect exposed structures.
D. Place a sterile, saline-soaked dressing on the wound: A moist sterile dressing protects the wound from contamination, prevents the tissues from drying, and reduces the risk of infection while awaiting further surgical evaluation.
Correct Answer is A
Explanation
A. Instill erythromycin ointment into the newborn's eyes: Erythromycin ophthalmic ointment is routinely applied to all newborns to prevent ophthalmia neonatorum, a serious eye infection caused by exposure to Neisseria gonorrhoeae during birth.
B. Give oral sulfadiazine to the mother prior to delivery: Sulfonamides are not recommended for gonorrhea treatment in laboring clients and are ineffective in preventing neonatal eye infections.
C. Administer penicillin G procaine IM to the newborn: Penicillin is used to treat confirmed neonatal infections, not as a routine prophylaxis against gonococcal eye infections.
D. Apply miconazole vaginal cream to the mother prior to delivery: Miconazole is an antifungal used for vaginal yeast infections and has no effect on gonorrhea, so it is not indicated for preventing neonatal infection.
