The nurse assesses a client's vital signs.Which client situation should be reported to the primary care provider?

A) Decreased blood pressure (BP) after standing up
B) Decreased temperature after a period of diaphoresis
C) Increased heart rate after walking down the hall
D) Increased respiratory rate when the heart rate increases

A decreased blood pressure after standing up may indicate orthostatic hypotension, which can be a sign of dehydration, medication side effects or underlying medical issues. This should be reported to the primary care provider for further evaluation and management. The other options are normal physiological responses to different stimuli and do not require immediate attention.
