A client with unstable angina pectoris receives a prescription for nitroglycerin 0.4 mg sublingually PRN chest pain every 5 minutes x3. The prescription directions include leaving the medication at the bedside for self-administration. Which assessment finding should the practical nurse (PN) obtain first?
Explanation & Rationale
A. While knowing the number of tablets taken is important for managing chest pain, it is secondary to ensuring that the client can safely administer the medication. B. Assessing the client's level of orientation and compliance is crucial because the client needs to understand how and when to use the nitroglycerin properly. Misunderstanding or non-compliance could lead to ineffective treatment or potential harm. C. Checking heart rate and blood pressure is important for assessing the effects of nitroglycerin, but before leaving the medication for self-administration, it is vital to ensure that the client understands how to use the medication. D. Monitoring hourly urinary output and daily weight is not relevant to the immediate concern of ensuring safe and effective nitroglycerin self-administration.
