A client is requesting information from a nurse about a nitrazine test. Which of the following statements should the nurse make?

A. "Empty the drainage bag every 12 hours.": Urine should be emptied regularly, but not on a fixed 12-hour schedule. The focus is on preventing backflow and maintaining sterility, so the bag should be emptied when it is two-thirds full or as needed, rather than strictly every 12 hours.

B. "Irrigate the indwelling urinary catheter once per shift.": Routine irrigation is not recommended for preventing catheter-associated urinary tract infections (CAUTIs) and can introduce pathogens or cause trauma. Irrigation should only be performed if specifically indicated for obstruction or provider order.

C. "Apply a topical antimicrobial ointment as part of routine catheter care.": Routine application of antimicrobial ointment is not recommended and does not prevent CAUTIs. Proper hygiene and sterile technique are more effective in infection prevention than topical agents.

D. "Keep the drainage bag below the level of the bladder.": Maintaining the drainage bag below the bladder prevents backflow of urine, which is a major risk factor for introducing bacteria into the urinary tract. This simple intervention is a key measure in reducing catheter-associated urinary tract infections.

A. Prepare for chest tube placement: Chest tube placement is indicated for conditions like pneumothorax or pleural effusion, which are not clearly present in this scenario. Immediate interventions should focus on stabilizing the client and evaluating cardiopulmonary status first.

B. Ensure that the client has venous access: Establishing IV access is essential for rapid administration of medications, fluids, or emergency interventions if the client’s condition deteriorates. This is a priority in acute postoperative complications.

C. Place the client in High Fowler's position: Elevating the head of the bed improves lung expansion, reduces dyspnea, and enhances oxygenation in a client experiencing sudden respiratory distress and crackles, which may indicate pulmonary edema or fluid overload.

D. Activate the rapid response team: The client exhibits acute respiratory distress, hypoxemia, tachypnea, and cardiovascular changes. Activating the rapid response team ensures timely advanced intervention and evaluation to prevent further deterioration.

E. Administer fondaparinux as prescribed: Postoperative clients following total hip arthroplasty are at high risk for venous thromboembolism. Administering anticoagulant therapy, such as fondaparinux, helps prevent pulmonary embolism, which could be causing the client’s sudden dyspnea.

F. Administer midazolam as prescribed: Midazolam is a sedative and would not address the client’s acute respiratory distress. Sedation could worsen hypoxemia and respiratory compromise in this scenario.
