Verified step by step guidance

Understand the condition: Urinary retention refers to the inability to completely empty the bladder. It can occur due to various reasons, including post-surgical effects on the nervous system or bladder muscles.

Review the pharmacological options: Each medication listed has a specific mechanism of action. Bethanechol is a cholinergic agonist that stimulates bladder contraction, Spironolactone is a diuretic that affects fluid balance, Furosemide is a loop diuretic, and Oxybutynin is an anticholinergic that relaxes bladder muscles.

Match the medication to the condition: Since urinary retention involves difficulty in bladder emptying, a medication that promotes bladder contraction (Bethanechol) would be appropriate. Diuretics like Spironolactone and Furosemide are used for fluid removal, not bladder contraction. Oxybutynin is used for overactive bladder, which is the opposite of urinary retention.

Consider the mechanism of Bethanechol: Bethanechol works by stimulating the parasympathetic nervous system, specifically muscarinic receptors, to enhance bladder muscle contraction and facilitate urination.

Confirm the choice: Based on the condition and the mechanism of action, Bethanechol is the correct medication to address urinary retention after surgery.
