A father asks why his child with Tetralogy of Fallot seems to favor a squatting position. What is the nurse's best response?

Squatting increases the return of venous blood flow to the heart.

Squatting in common resting position when a child is tachycardic

Squatting decreases arterial blood flow away from the heart.

Squatting increase the workload of the heart.

Answer and Explanation

The Correct Answer is A

A. Squatting increases the return of venous blood flow to the heart: Squatting increases systemic vascular resistance and venous return, which helps to increase oxygenation in children with Tetralogy of Fallot, as it reduces the right-to-left shunting and increases blood flow to the lungs.

B. Squatting in common resting position when a child is tachycardic: While squatting can be used to manage symptoms, this answer is misleading as squatting specifically helps in increasing blood flow and decreasing the symptoms of cyanosis in Tetralogy of Fallot, not just during tachycardia.

C. Squatting decreases arterial blood flow away from the heart: Squatting actually increases blood flow to the heart and lungs by increasing systemic vascular resistance.

D. Squatting increases the workload of the heart: Squatting helps reduce the workload on the heart in Tetralogy of Fallot by improving oxygenation and decreasing cyanosis.

Correct Answer is C

Explanation

A. Tetralogy of Fallot: A cyanotic defect that decreases pulmonary blood flow due to pulmonary stenosis.

B. Coarctation of the aorta: Involves narrowing of the aorta, which affects systemic circulation, not pulmonary blood flow.

C. Patent ductus arteriosus: Causes increased pulmonary blood flow as blood shunts from the aorta to the pulmonary artery due to the open ductus arteriosus.

D. Tricuspid atresia: A cyanotic defect that decreases pulmonary blood flow by preventing blood from passing through the tricuspid valve.

A. "I should give the iron with milk to help prevent stomach upset." B. "My child should avoid eating citrus fruits while taking the supplements." C. "I should take my child to the emergency room if his stool becomes dark." D. "My child should take the supplement through a straw."

Correct Answer is D

Explanation

A. "I should give the iron with milk to help prevent stomach upset.": Milk should not be given with iron supplements as it can decrease the absorption of iron. Vitamin C is often recommended with iron to enhance absorption.

B. "My child should avoid eating citrus fruits while taking the supplements.": Citrus fruits, which are high in vitamin C, actually help increase the absorption of iron, so they should not be avoided.

C. "I should take my child to the emergency room if his stool becomes dark.": Dark stools are a common and harmless side effect of iron supplementation due to unabsorbed iron, so this is not an emergency situation.

D. "My child should take the supplement through a straw.": Liquid iron supplements can stain the teeth. To avoid this, it is recommended to give the supplement through a straw to minimize contact with the teeth.
