A charge nurse is teaching a group of nurses about fire safety. Which of the following statements by a nurse indicates an understanding of the teaching?

A. Keep the urinary bag at bladder level when ambulating: The urinary drainage bag should always be kept below the level of the bladder to promote gravity drainage and prevent backflow of urine. Keeping it at bladder level increases the risk of urine reflux into the bladder, which can introduce bacteria and lead to infection.

B. Secure the catheter to the client's thigh: Securing the catheter prevents traction and movement at the urethral meatus, which can cause microtrauma and facilitate bacterial entry. Stabilization also maintains a closed drainage system, reducing the risk of catheter-associated urinary tract infections (CAUTIs).

C. Obtain urinary samples by disconnecting the tubing connections: Disconnecting the closed drainage system increases the risk of introducing microorganisms into the system. Urine specimens should be obtained from the designated sampling port using aseptic technique to maintain sterility and reduce infection risk.

D. Loop the tubing so that it is lower than the collection bag: Tubing should be free of dependent loops because these can trap urine and promote bacterial growth. Additionally, positioning tubing lower than the collection bag can lead to backflow, increasing the risk of infection.

A. Scant lochia rubra with a few small clots: Lochia rubra is expected during the first 3–4 days postpartum and may include small clots due to uterine involution and sloughing of the decidua. Scant flow with small clots is within normal limits and does not indicate a complication unless bleeding becomes excessive or clots are large.

B. Bilateral ankle edema: Mild bilateral lower extremity edema is common in the postpartum period due to fluid shifts and increased vascular volume during pregnancy. It typically resolves with diuresis over several days and is not concerning unless accompanied by unilateral swelling, pain, or signs of thromboembolism.

C. Urine output 2,500 mL/day: Increased urine output is expected postpartum as the body eliminates excess fluid accumulated during pregnancy. A diuresis of up to 3,000 mL/day can occur within the first few days after delivery and reflects normal physiologic adjustment.

D. 4+ deep-tendon reflexes: Hyperreflexia (4+ DTRs) is an abnormal finding and may indicate central nervous system irritability associated with postpartum preeclampsia. It increases the risk for seizures (eclampsia) and requires immediate evaluation and intervention, such as magnesium sulfate therapy.
