A nurse is assessing a patient who started to have severe pain 3 days ago. When the nurse asks the patient to describe the pain, the patient states, “The pain feels like it is my stomach. It is a burning pain, and it spreads out in a circle around the spot where it hurts the most.” Which type of pain does the nurse document the patient is having at this time?

Choice A reason: Preventing bathroom interruptions is not the primary rationale. While convenient, indwelling catheters are used for clinical reasons like monitoring or preventing complications. This rationale overlooks the physiological effects of surgery and anesthesia, which are more critical for catheter use in abdominal procedures.

Choice B reason: Checking patency post-surgery is not the primary reason for intraoperative catheter placement. While catheters monitor urine output, the main goal is to manage bladder function during and immediately after surgery, when anesthesia and surgical manipulation increase retention risks, not just patency.

Choice C reason: Anesthetics, especially general or spinal, reduce detrusor muscle contractility, impairing bladder emptying. This increases urinary retention risk during and post-surgery. An indwelling catheter ensures continuous drainage, preventing bladder overdistention, discomfort, or complications like urinary tract infections or bladder injury.

Choice D reason: Uncontrolled voiding during surgery is unlikely under anesthesia, which suppresses bladder reflexes. While catheters prevent intraoperative bladder filling, the primary concern is retention from anesthetic effects, not involuntary voiding, making this rationale less accurate for catheter use.

Choice A reason: Furosemide 60 mg requires 1.5 tablets of 40 mg (60 ÷ 40 = 1.5). Scored tablets allow precise division, ensuring the correct dose. This calculation aligns with safe medication administration principles, delivering the prescribed amount accurately.

Choice B reason: Administering 2.5 tablets (100 mg) exceeds the prescribed 60 mg dose. Overdosing furosemide, a loop diuretic, risks excessive diuresis, leading to dehydration, hypokalemia, or hypotension, making this choice unsafe and incorrect.

Choice C reason: Two tablets (80 mg) also exceed the 60 mg order. This overdose could cause significant fluid and electrolyte imbalances, particularly in vulnerable patients, as furosemide promotes rapid sodium and water excretion, making this choice inappropriate.

Choice D reason: One tablet (40 mg) underdoses the patient, providing only 66.7% of the prescribed 60 mg. Inadequate dosing may fail to achieve therapeutic effects, such as edema reduction or blood pressure control, rendering this choice incorrect.
