When treating hypertensive emergencies, the nurse identifies the most appropriate route of administration for antihypertensive agents as being which of the following?
Continuous IV infusion
Sublingual
Intramuscular
Oral
The Correct Answer is A
A. Continuous IV infusion is the most appropriate route for treating hypertensive emergencies because it allows for rapid and controlled reduction of blood pressure, which is crucial in preventing target organ damage.
B. Sublingual administration is not recommended in hypertensive emergencies because it does not allow for the precise control needed in these situations.
C. Intramuscular administration is generally not used for antihypertensive agents in emergencies because it does not provide the rapid and adjustable response that IV infusion does.
D. Oral administration is too slow in onset for hypertensive emergencies and is not appropriate when immediate blood pressure control is necessary.
