A nurse is preparing to administer propranolol to a client. Which of the following should the nurse assess prior to administering this medication?

C. Propranolol can cause bradycardia, especially in clients with pre-existing bradycardia or conditions where reducing heart rate may be detrimental (e.g., heart block). Monitoring heart rate helps detect potential adverse effects and guides appropriate dosing adjustments.A. Propranolol is primarily used to treat conditions such as hypertension, angina, arrhythmias, and migraine prophylaxis. It does not directly affect pain perception or management.B. Propranolol does not have direct effects on body temperature regulation or fever. Temperature assessment would be indicated if there were concerns related to infection or hyperthermia.D. Propranolol can exacerbate bronchospasm in clients with asthma or chronic obstructive pulmonary disease (COPD). While respiratory rate may be assessed based on clinical judgment and client history, it is not the highest priority assessment compared to heart rate when preparing to administer propranolol.
