A nurse is assisting the guardians of a newborn with the transition to parenthood. Which of the following actions should the nurse take?

A. Hold the catheter with the dominant hand during insertion: The dominant hand should be used to insert the catheter because it provides better control and precision during the sterile procedure. The nondominant hand is used to expose and maintain the position of the urethra but is considered contaminated once touching the client.

B. Advance catheter 7.5 cm (3 in) after urine begins to flow: The catheter should be advanced approximately 2.5 to 5 cm (1 to 2 inches) further after urine appears, not 7.5 cm. Advancing too far could cause discomfort or trauma to the bladder.

C. Hang collection bag below the level of the bladder: While this is an important step in managing the catheter after insertion to prevent backflow and infection, it does not specifically pertain to the insertion process itself.

D. Lubricate the catheter 12.5 cm (5 in) prior to insertion: Typically, for female catheterization, about 2.5 to 5 cm (1 to 2 inches) of the catheter is lubricated, not 12.5 cm. Excessive lubrication is unnecessary and may cause difficulty during insertion.

• Pneumonia: The preschooler is showing signs of shallow breathing, refusal to use the incentive spirometer, and slightly diminished breath sounds in the bilateral lower lobes, all of which increase the risk of developing pneumonia. Postoperative patients, especially young children, are vulnerable to pneumonia due to pain-limited deep breathing and poor pulmonary expansion.
• Wound infection: Although there is some serosanguinous drainage at the incision site, the dressing remains dry overall, and there is no mention of redness, warmth, or purulent discharge typically associated with wound infection. Therefore, wound infection is not the primary concern at this point.
• Ileus: Hypoactive bowel sounds are present, but they have been stable throughout the day without worsening abdominal distension or absence of bowel function. While ileus is a postoperative risk, the more pressing concern given the respiratory findings is pneumonia.
• Shallow breathing: The child consistently shows shallow, unlabored respirations throughout assessments, which indicate limited lung expansion. Without effective use of the incentive spirometer and adequate deep breathing, shallow breathing places the child at high risk for pulmonary complications such as pneumonia.
• Increasing temperature: Although the child's temperature rose slightly by 1600, it remains below 38° C (100.4° F), which is not typically classified as a fever. The minor temperature elevation could be related to inflammation rather than an infectious process at this stage.
• Hypoactive bowel sounds: Hypoactive bowel sounds are expected in the early postoperative period, particularly following abdominal surgery due to the effects of anesthesia and manipulation of the bowel during surgery. While they should be monitored, they are not the primary finding indicating the most urgent complication in this situation.
