A patient is being treated for hypertensive emergency. When treating this patient, the nurse recognizes the initial goal is to lower the mean blood pressure (BP) by 20-25% because

the goal is to lower the BP to 120/80.

lowering the BP quickly may decrease cerebral, coronary or renal perfusion.

IV antihypertensive medications have a slow onset.

Lowering the BP slowly allows the patient to rest.

Answer and Explanation

The Correct Answer is B

A. While lowering BP to 120/80 may be an ultimate goal, it is not the initial target in a hypertensive emergency.

B. Rapid reduction in blood pressure can cause hypoperfusion of vital organs such as the brain, heart, and kidneys, leading to ischemic injury. The aim is to reduce the BP gradually to prevent these complications.

C. IV antihypertensive medications generally have a rapid onset, not a slow one.

D. While gradual reduction is important, it is not done to allow rest but to protect organ perfusion.

Correct Answer is C

Explanation

A. A depressed ST-segment is often associated with ischemia or non-ST elevation myocardial infarction (NSTEMI), not an ongoing MI.

B. A depressed ST-segment with normal cardiac enzymes suggests ischemia rather than an active MI.

C. ST-segment elevation on ECG combined with elevated cardiac biomarkers such as CK-MB or troponin levels is a hallmark of an acute ST-segment elevation myocardial infarction (STEMI), indicating an ongoing MI.

D. A Q wave on ECG indicates an old infarction and is not associated with an acute MI if enzymes and troponin levels are normal.

A. Numbness and tingling to the left hand. B. Slight bloody drainage at the subclavian insertion site. C. Dressing is beginning to lift around the insertion site. D. Slight redness at the subclavian insertion site.

Correct Answer is A

Explanation

A. Numbness and tingling in the left hand could indicate compromised blood flow or nerve damage, potentially due to the arterial line, requiring immediate assessment and intervention.

B. Slight bloody drainage is a common finding and typically does not require immediate action.

C. A dressing beginning to lift should be addressed to maintain a sterile environment but is not an emergency.

D. Slight redness at the insertion site may indicate mild irritation or early signs of infection, but it does not require immediate intervention compared to the potential vascular or nerve compromise suggested by numbness and tingling.
