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. Coronary artery bypass graft B. Percutaneous coronary artery intervention C. Nothing, because the patient is in terminal heart failure D. Left ventricular assist device (LVAD)

Correct Answer is D

Explanation

A. A coronary artery bypass graft is used to treat coronary artery disease but is not typically indicated for end-stage heart failure.
B. Percutaneous coronary intervention is also used for coronary artery disease, not for improving quality of life in terminal heart failure.
C. This option dismisses potential interventions that could improve quality of life, such as an LVAD.
D. An LVAD is a mechanical pump that assists the left ventricle in pumping blood, often used as a bridge to heart transplant or as a long-term solution to improve quality of life in patients with terminal heart failure.
