After teaching a class about the hemodynamic characteristics of congenital heart disease, the instructor determines that the teaching has been successful when the class identifies which defect as an example of a disorder involving increased pulmonary blood flow?
Transposition of The Great Arteries
Coarctation of the Aorta
Patent Ductus Arteriosus
Tetralogy of Fallot
The Correct Answer is C
A. Transposition of The Great Arteries involves abnormal positioning of the arteries, leading to systemic and pulmonary circulations being disconnected, rather than increased pulmonary blood flow.
B. Coarctation of the Aorta is a narrowing of the aorta that can cause increased pressure in the upper extremities but does not involve increased pulmonary blood flow.
C. Patent Ductus Arteriosus (PDA) is a condition where the ductus arteriosus fails to close, causing increased blood flow to the lungs, leading to pulmonary overcirculation.
D. Tetralogy of Fallot leads to decreased pulmonary blood flow due to pulmonary stenosis and right ventricular hypertrophy.

A. Staying home for 2 weeks is excessive; typically, 24 to 48 hours of antimicrobial therapy is enough before the child is no longer contagious.
B. While discharge is a sign of infection, the child can often return to school after receiving treatment for 24 to 48 hours.
C. This is correct. Bacterial conjunctivitis is contagious, and children should stay home until they've been on antibiotics for 24 to 48 hours to reduce transmission.
D. This is incorrect; the child should stay home for 24 to 48 hours after starting treatment, as they can still be contagious during that time.
