You are the Emergency Department consultant acting as EPIC when a GP working in the out-of-hours clinic adjacent to the ED contacts you for advice about a 34-year-old man who attended with persistent headaches.

Repeated clinic blood pressure measurements during the consultation were 186/112 mmHg. He has no previous history of hypertension. On further questioning, he reports recent episodes of palpitations, sweating, and headaches over the past several months. Physical examination is otherwise unremarkable and there are no focal neurological deficits.

The GP asks what the most appropriate clinical consideration should be in this scenario.

Which of the following best explains the appropriate clinical approach?
