Final answer:
Mary may be experiencing orthostatic hypotension as a side effect of the anti-hypertensive medication. You should ensure her safety, monitor her vitals, provide fluids for hydration, have her avoid sudden postural changes, and consult a healthcare professional for further instructions.
Step-by-step explanation:
If Mary started complaining of dizziness after you administered an anti-hypertensive medication, it is possible that she is experiencing orthostatic hypotension, which can occur when there is insufficient blood reaching the brain.
This could be due to the medication causing a sudden drop in blood pressure, particularly when changing positions from sitting or lying down to standing.
The cardiovascular system faces a challenge in keeping blood flowing to the brain against gravity, and if the blood volume is too low or the body's sympathetic reflex is not effective, dizziness can occur.
There are several steps you should take in this situation:
- Ensure Mary is in a safe position, preferably seated or lying down, to prevent falls.
- Monitor her vital signs, including blood pressure and heart rate.
- Encourage her to drink fluids if dehydration is suspected.
- Advise Mary to avoid sudden changes in posture and to rise slowly to a standing position.
- Consult with a healthcare professional for further evaluation and possible adjustment of her medication.
The immediate goal is to stabilize her condition and then address the underlying cause of the orthostatic hypotension, which might involve adjusting the dosage or type of anti-hypertensive medication she is taking.
