A nurse is assessing a child who has a congenital heart defect. The nurse should recognize that which of the following defects is associated with increased pulmonary blood flow?
Coarctation of the aorta
Patent ductus arteriosus
Tetralogy of Fallot
Tricuspid atresia
The Correct Answer is B
A. Coarctation of the aorta
Coarctation of the aorta involves a narrowing of the aorta, leading to decreased blood flow to the lower body. It is not associated with increased pulmonary blood flow.
B. Patent ductus arteriosus
Patent ductus arteriosus (PDA) is a congenital heart defect where the ductus arteriosus, a fetal blood vessel that usually closes shortly after birth, remains open. This allows blood to flow from the aorta into the pulmonary artery, increasing pulmonary blood flow. Therefore, option B is correct.
C. Tetralogy of Fallot
Tetralogy of Fallot is a congenital heart defect characterized by four abnormalities, including a ventricular septal defect (VSD), pulmonary stenosis, right ventricular hypertrophy, and an overriding aorta. While it can lead to cyanosis due to right-to-left shunting, it is not primarily associated with increased pulmonary blood flow.
D. Tricuspid atresia
Tricuspid atresia involves the absence of the tricuspid valve, leading to a lack of direct blood flow from the right atrium to the right ventricle. It usually presents with decreased pulmonary blood flow rather than increased pulmonary blood flow.

Correct Answer is B
Explanation
A. "Seal nonwashable items in a plastic bag for 2 days."
This instruction is incorrect. Items that cannot be laundered may be dry-cleaned or sealed in a plastic bag for two weeks
B. "Soak hair brushes in boiling water for 10 minutes."This is correct. According to CDC, combs and brushes should be soaked in hot water (at least 130 degrees fahrenheit) to help avoid re-infestation.
C. "Apply permethrin 1 percent cream rinse every day for 5 days."
This instruction is incorrect. Permethrin 1 percent cream rinse is a medication used to treat head lice infestations, but it is typically applied only once and then rinsed out after a specified period of time (usually 10 minutes). Repeated daily application for five days is not recommended and may lead to unnecessary exposure to the medication.
D. "After washing bed linens, place them in a dryer on a cool setting for 30 minutes."
This instruction is incorrect. To effectively kill lice and nits on bed linens, they should be washed in hot water (at least 130°F or 54°C) and then dried on a hot setting in the dryer. A cool setting may not be sufficient to kill lice and nits.
Correct Answer is C
Explanation
A. Visual acuity 20/30 bilaterally: Visual acuity of 20/30 bilaterally indicates relatively good vision in both eyes, but it does not necessarily indicate strabismus. Strabismus is related to eye alignment rather than visual acuity.
B. Peripheral vision 70° downward: Peripheral vision refers to the ability to see objects outside the direct line of vision. While changes in peripheral vision can occur in various eye conditions, such as glaucoma, it is not specific to strabismus.
C. Movement of the uncovered eye during a cover test: This is the correct option. During a cover test, one eye is covered while the other eye fixates on an object. If the uncovered eye moves to try to align with the covered eye, it may indicate strabismus or a misalignment of the eyes.
D. Light reflects symmetrically within each pupil during a corneal light reflex test: A corneal light reflex test assesses the alignment of the eyes by observing the reflection of light on the corneas. While asymmetry in the corneal light reflex can indicate strabismus, the description provided in this option suggests that the light reflects symmetrically within each pupil, which is a normal finding.
