Correct Answer is ["A","D","E","F"]

Explanation

A. Right ventricular hypertrophy is part of the pathophysiology of TOF, resulting from the increased workload on the right ventricle due to pulmonary stenosis.

B. Left ventricular hypertrophy is not part of TOF; the condition primarily affects the right ventricle.

C. Patent ductus arteriosus (PDA) is not a characteristic of TOF, although it may be present in some cases, it's not part of the primary defects.

D. Ventricular septal defect (VSD) is a primary defect in TOF, which allows blood to mix between the left and right ventricles.

A. Place the patch on the right eye for several hours daily B. Place the patch on the left eye for several hours daily C. Place the patch on the right eye for one hour daily D. Alternate the patch from the right to the left eye hourly

Correct Answer is B

Explanation

A. Place the patch on the right eye for several hours daily would not be effective for treating amblyopia. The goal of patching is to encourage the use of the weaker (lazy) eye, so the good eye (left) must be patched.

B. Place the patch on the left eye for several hours daily is the correct approach to treat amblyopia, as it forces the right (weaker) eye to work and improve visual acuity.

C. Place the patch on the right eye for one hour daily would not effectively treat the amblyopia in the left eye, as it focuses on the wrong eye.

D. Alternate the patch from the right to the left eye hourly is not typically done. Consistent patching of the stronger (left) eye is recommended.
