The nurse is caring for a patient taking a cholinergic agent. When auscultating lung sounds, the nurse notes inspiratory and expiratory wheezing bilaterally. The best action for the nurse to take would be to:

A. Withhold the next dose and notify the physician:

Withholding the next dose of the cholinergic agent is the appropriate immediate action because the presence of inspiratory and expiratory wheezing bilaterally suggests bronchoconstriction or bronchospasm, which can be a serious adverse reaction to the medication. Notifying the physician promptly allows for further assessment and management of the patient's respiratory symptoms. The physician may need to adjust the medication regimen, order diagnostic tests, or provide treatment for bronchoconstriction.

B. Give the next dose:

Administering the next dose of the cholinergic agent could worsen the patient's respiratory symptoms and exacerbate bronchoconstriction. This action is contraindicated in the presence of wheezing, as it may further compromise the patient's respiratory function.

C. Assess heart rate:

While assessing heart rate is an important aspect of patient assessment, it is not the priority in this scenario. The priority is to address the respiratory distress and potential bronchoconstriction associated with the cholinergic agent. Wheezing is a respiratory symptom that suggests airway obstruction, and immediate intervention is necessary to ensure adequate oxygenation and ventilation.

D. Assess blood pressure:

Similarly, while assessing blood pressure is important in patient care, it is not the priority in this situation. The priority is to address the respiratory distress and potential bronchoconstriction associated with the cholinergic agent. Wheezing indicates respiratory compromise, and prompt action is required to prevent further respiratory deterioration.
