For which client should a nurse clarify the prescription for propranolol?

Propranolol is a non-selective beta-blocker that can have significant effects on the respiratory system, making it particularly concerning for clients with asthma. In individuals with asthma, non-selective beta-blockers can potentially cause bronchoconstriction due to their action on beta-2 adrenergic receptors in the lungs. This could exacerbate asthma symptoms or lead to an acute asthma attack, which poses a serious risk to the patient's health.

Clarifying the prescription for a client with a history of asthma ensures the nurse is providing safe and appropriate care, considering the potential for adverse effects. In contrast, propranolol may be beneficial for clients with hypertension, diabetes (with careful monitoring of blood glucose levels), and hyperthyroidism to manage tachycardia and other symptoms, making those scenarios less concerning compared to a client with asthma.
