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
Explanation
A. Urinary output 20 mL/hr: A urinary output less than 30 mL/hr in an adult indicates potential renal hypoperfusion or urinary retention. This is a priority finding that should be reported to the provider promptly.
B. Serous drainage on abdominal dressing: Serous drainage is a normal postoperative finding, indicating normal wound healing and fluid exudate. It does not require immediate provider notification.
C. Temperature 37.6° C (99.7° F): This temperature is slightly elevated but within the expected postoperative range due to the inflammatory response. It does not indicate an urgent complication.
D. Blood pressure 100/70 mm Hg: This blood pressure is within normal limits for many adults and is not necessarily concerning in a postoperative context unless accompanied by other symptoms such as tachycardia or dizziness.
Correct Answer is {"A":{"answers":"A"},"B":{"answers":"B"},"C":{"answers":"A"},"D":{"answers":"A"}}
Explanation
- Blood pressure: At 2100, the client’s BP was 90/56 mm Hg, indicating hypotension likely from postpartum hemorrhage. By 2115, BP increased to 108/72 mm Hg, showing improved hemodynamic stability after interventions such as fundal massage, oxytocin administration, and bladder emptying.
- Skin temperature: At both 2100 and 2115, the client’s skin remained cool to the touch. This could indicate ongoing peripheral vasoconstriction or residual hypoperfusion, suggesting that although circulation improved, thermoregulation and peripheral perfusion have not fully normalized.
- Fundal assessment: Initially, the fundus was boggy, deviated to the right, and 2 cm above the umbilicus, indicating uterine atony worsened by bladder distention. After catheterization and uterotonic therapy, the fundus became midline, firm, and at the level of the umbilicus, which is expected postpartum and reduces bleeding risk.
- Bleeding: At 2100, there was heavy lochia rubra saturating a perineal pad in 20 min with passage of a large clot. At 2115, bleeding decreased to a moderate amount of lochia rubra with a few pea-sized clots, indicating that hemorrhage control measures were effective.
