Before administering an antihypertensive medication, which data should be documented?

• A. The patient's blood pressure prior to giving the antihypertensive
• B. The patient's heart rate
• C. The patient's temperature
• D. The patient's respiratory rate

Answer: (A)

Baseline blood pressure is the key data to document before giving an antihypertensive. Knowing the patient’s starting pressure provides a reference to assess the drug’s effect after administration and to detect dangerous drops in BP. It helps determine whether it’s safe to proceed and guides dose decisions, ensuring safety for the patient. Other vital signs have value in overall assessment, but they aren’t the primary data needed to guide antihypertensive dosing. Temperature isn’t directly related to BP control; respiratory rate and heart rate are important in certain contexts or with specific drug classes, but they aren’t the universal baseline used to determine whether to administer an antihypertensive.
