Before administering bethanechol chloride subcutaneously, which condition should the nurse ensure is not in the client's history?

Bethanechol chloride is a medication that stimulates the parasympathetic nervous system, primarily affecting the bladder to increase urinary tract tone and stimulate bladder contractions. This medication is particularly useful in treating urinary retention but can have significant effects on the respiratory system.

When considering the administration of bethanechol chloride, it is essential to ensure that the client does not have a history of asthma. This is because the drug can cause bronchoconstriction due to its cholinergic effects, which may exacerbate respiratory conditions like asthma. In individuals with asthma, increased secretions and bronchospasm can lead to significant breathing difficulties, making this medication potentially harmful.

In contrast, while conditions like COPD, diabetes, and heart disease are also important to consider when administering any medication, the direct respiratory impact of bethanechol chloride makes a history of asthma particularly concerning. Therefore, ensuring that the client does not have asthma helps mitigate the risk of serious respiratory complications associated with this medication.
