Correct Answer is D
Explanation
A. Electroencephalogram (EEG) measures electrical activity of the brain, not cardiac function.
B. KUB (Kidneys, Ureters, Bladder) is an X-ray used to assess the urinary tract, not heart function.
C. Dexascan (DEXA) is used to measure bone density, unrelated to heart function.
D. Cardiac catheterization is an invasive diagnostic procedure that allows direct measurement of cardiac pressures and evaluation of coronary arteries. It can be used to assess cardiac function including ejection fraction, either directly or with adjunctive imaging like ventriculography. Additionally, echocardiography is commonly used non-invasively to measure ejection fraction but among the given options, cardiac catheterization is the correct answer
Correct Answer is B
Explanation
A. Hypertrophy increases oxygen demand but does not improve cardiac function; it typically worsens ejection fraction.
B. Hypertrophy and remodeling initially help compensate but over time lead to inefficient heart muscle with poor contractility and increased oxygen demand, contributing to worsening heart failure.
C. Hypertrophy and remodeling increase, not reduce, workload, and do not resolve heart failure.
D. Contractility often declines and oxygen demand increases, contrary to this statement.
