What are the goals of treatment for peripheral arterial disease?

Choice A reason: Laying the infant with the head lower than the body worsens cyanosis in tetralogy of Fallot by reducing systemic venous return. The knee-to-chest position increases resistance, improving oxygenation, making this incorrect, as it indicates a need for further teaching on proper positioning.

Choice B reason: Holding the infant against the shoulder with knees bent up toward the chest is the correct knee-to-chest position for tetralogy of Fallot during cyanosis. This increases systemic vascular resistance, reducing right-to-left shunting and improving oxygenation, indicating the father’s understanding of the instructions.

Choice C reason: Placing the infant upright in an infant seat does not effectively increase systemic vascular resistance to reduce shunting in tetralogy of Fallot. The knee-to-chest position is required, making this incorrect, as it shows a need for teaching on the correct positioning to manage cyanosis.

Choice D reason: Supine position with head elevated does not address cyanosis in tetralogy of Fallot, as it fails to increase systemic resistance to reduce shunting. Knee-to-chest positioning is needed, making this incorrect, as it indicates misunderstanding of the proper technique to improve oxygenation.

Choice A reason: Increased mobility is beneficial for general health but must be cautious in heart failure to avoid overexertion, which can exacerbate cardiac strain and fluid overload. Dietary and fluid restrictions are more critical to manage volume status, making mobility a secondary focus in discharge teaching for heart failure.

Choice B reason: Dietary and fluid restrictions, particularly low-sodium diets and limited fluid intake, are essential in heart failure to reduce fluid overload, preload, and cardiac workload. This prevents exacerbations like pulmonary edema, making it a priority lifestyle modification to include in discharge teaching for effective heart failure management.

Choice C reason: Cessation of intravenous drug use is relevant for specific populations but not a general heart failure management strategy. It does not directly address fluid overload or cardiac workload, unlike dietary and fluid restrictions, making it an incorrect focus for routine discharge teaching in heart failure.

Choice D reason: Cessation of hormonal supplements is not typically relevant to heart failure management unless specific hormones affect fluid balance or cardiac function. Dietary and fluid restrictions directly address the pathophysiology of fluid overload, making this an incorrect lifestyle modification for routine heart failure discharge teaching.
