Inhaled Glucocorticoid
Beta Adrenergic Blocker
Cardiac Glycoside
Angiotensin Enzyme Inhibitor
The Correct Answer is C
A. Inhaled Glucocorticoid: Used for managing asthma or other respiratory conditions, not for cardiac function.
B. Beta Adrenergic Blocker: Reduces blood pressure and heart rate but is not the mechanism of Digoxin.
C. Cardiac Glycoside: Digoxin is used to improve myocardial contractility and slow the heart rate, which aligns with this classification.

Correct Answer is C
Explanation
A. Lack of adequate ventricle strength to pump blood to the body: While right ventricular hypertrophy is part of Tetralogy of Fallot, the primary cause of fatigue is inadequate oxygenation, not muscle strength.
B. Restricted blood flow leaving the heart: This contributes to low oxygen levels but isn’t the direct reason for fatigue; the issue lies in oxygen availability for metabolism.
C. Inadequate oxygenation for supporting energy metabolism: The structural defects cause reduced oxygen delivery to tissues, leading to fatigue during activities like feeding.
D. Increased circulation pressure to the lungs: Pulmonary stenosis reduces blood flow to the lungs, but this doesn’t directly explain fatigue from eating.
