For a client with urinary retention prescribed bethanechol chloride, which disorder is a contraindication for this medication?

Bethanechol chloride is a medication that stimulates the bladder muscle and promotes urination by acting on the cholinergic receptors. For a client with urinary retention, it is often prescribed to help facilitate the process of emptying the bladder.

In the context of contraindications, urinary strictures represent a significant concern. A urinary stricture is a narrowing of the urethra that can hinder urine flow. By using bethanechol, the urinary bladder may contract more vigorously to push urine out, but if there is a blockage caused by a stricture, this contraction could lead to increased pressure within the bladder and potential complications such as bladder damage or severe discomfort. Thus, administering bethanechol in the presence of urinary strictures poses a risk of worsening the client's condition or leading to acute urinary retention.

The other options listed do not present the same level of contraindication with bethanechol. Gastric atony and neurogenic atony may indicate a need for stimulation of smooth muscle activity and are not directly related to urinary flow obstructions. Gastroesophageal reflux could also be managed alongside the usage of bethanechol, as this condition does not directly interfere with the medication's action in the bladder. Therefore, urinary strictures are specifically a contraindication for
