Answer:
The patient's blood pressure (vasomotor) system is "untuned"
Explanation:
There is likelihood for venous pooling to occur as a result of improper constriction of the peripheral blood vessels. Furthermore, the medications that the patient may have been receiving may have effect on the blood pressure, thereby causing a reduction in blood pressure. There is also a possibility that the patient has not taken enough fluid and may not have been on intravenous fluids. These are likely factors that can cause postural orthostatic hypotension in a patient standing for the first time in 3 weeks.
