Assessing Vital signs:
Assessing vital signs includes measuring temperature, blood pressure, pulse rate, and respiration.
Temperature change can result from:
- cardiovascular inflammation or infection (higher than normal temperature)
- increased metabolism, which heightens cardiac workload (higher than normal temperature)
- poor perfusion and certain metabolic disorders such as hypothyroidism (lower than normal temperature).
According to the American Heart Association (AHA), three successive readings of blood pressure above 140/90 mm Hg indicate hypertension. However, emotional stress caused by physical examination may elevate blood pressure. If the patient’s blood pressure is high, allow him to relax for several minutes and then measure again to rule out stress.
