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

A. Temperature is not the primary assessment needed before administering propranolol. While it is important to monitor vital signs, temperature does not directly impact the administration of propranolol. B. Respiratory rate is important to monitor, but it is not the primary assessment needed before administering propranolol. Propranolol primarily affects the cardiovascular system. C. Pain level is not directly related to the administration of propranolol. While pain management is important, it does not influence the decision to administer propranolol. D. Heart rate is the primary assessment needed before administering propranolol. Propranolol can cause bradycardia (slow heart rate), so it is crucial to check the client’s heart rate before administration. If the heart rate is below 60 beats per minute, the medication should be withheld, and the provider should be notified.
