Final answer:
The statement regarding the client forgetting to take their nitroglycerin necessitates contacting the provider, as it is essential to prevent an angina attack during the stress of an exercise ECG. Other options typically do not require rescheduling, but the consumption of coffee could affect the test results.
Step-by-step explanation:
The exercise ECG test is intended to assess how the heart responds to stress, typically induced by exercise. In patients with a history of angina, particular care must be taken to manage potential risks associated with the test. Among the options provided, the statement that requires the nurse to contact the provider for possible rescheduling is:
b) "I forgot to take my nitroglycerin before coming here."
Pre-test administration of nitroglycerin is crucial for patients with stable angina who rely on it to prevent angina attacks, which can be precipitated by the exertion of the test itself. Missing this medication can lead to an increased risk of a stable angina attack becoming unstable angina, which requires urgent medical attention as it can be a sign of an impending heart attack. Therefore, it would be necessary to discuss with the provider whether to reschedule the exercise ECG to ensure patient safety.
Regarding the other options, a light breakfast, consumption of coffee, and adherence to prescribed beta-blockers generally do not require rescheduling. However, the intake of coffee could potentially affect the test results due to its stimulant effect, and some protocols may require avoidance of caffeine prior to the test; this aspect might also warrant a check with the provider.
