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
Rationale:
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.

Correct Answer is D
Explanation
Rationale:
A. CK-MB is a cardiac enzyme that rises in response to myocardial injury, but it is less specific and takes longer to rise than troponin.
B. BNP is associated with heart failure, not myocardial infarction.
C. Myoglobin is an early marker but is non-specific, as it rises with any muscle damage.
D. Troponin is the most specific and sensitive biomarker for myocardial infarction. It rises within 3-4 hours after myocardial injury and remains elevated for days, making it the most useful test for confirming an MI.
Correct Answer is A
Explanation
Rationale:
A. Sudden weight gain can indicate fluid retention, a common early sign of heart failure exacerbation. Prompt reporting allows for early intervention.
B. Nitroglycerin is used to treat chest pain, not specifically to prevent heart failure exacerbations.
C. Assessment of the apical pulse is important, but monitoring weight is more directly related to managing heart failure.
D. Compliance with diuretic therapy is important, but recognizing early signs of fluid retention, such as rapid weight gain, is crucial for preventing exacerbations.
