Which of the following describes a situation in which the blood pressure is severely elevated and there is evidence of actual target organ damage?
Secondary hypertension
Hypertensive urgency
Hypertensive emergency
Primary hypertension
The Correct Answer is C
Rationale:
A. Secondary hypertension is high blood pressure due to an identifiable cause, such as renal disease, but it does not describe an acute situation with target organ damage.
B. Hypertensive urgency is a situation where the blood pressure is severely elevated but without evidence of target organ damage.
C. Hypertensive emergency is characterized by severely elevated blood pressure with evidence of acute target organ damage, such as encephalopathy, myocardial infarction, or renal failure, requiring immediate medical intervention.

Correct Answer is D
Explanation
Rationale:
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.
Correct Answer is B
Explanation
Rationale:
A. Spironolactone is a potassium-sparing diuretic, so it would not cause hypokalemia.
B. Furosemide is a loop diuretic that causes the kidneys to excrete potassium, leading to hypokalemia.
C. Metoprolol is a beta-blocker and does not directly affect potassium levels.
D. Nitroglycerin is a vasodilator and does not affect potassium levels.
