A school nurse is assessing the visual acuity of a school-age child. Which of the following findings indicate that the child should be evaluated for strabismus?
Visual acuity 20/30 bilaterally
Peripheral vision 70° downward
Movement of the uncovered eye during a cover test
Light reflects symmetrically within each pupil during a corneal light reflex test
The Correct Answer is C
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.

Correct Answer is D
Explanation
A. Depressed scalp veins: This is an incorrect choice. In hydrocephalus, there is increased pressure within the skull due to the accumulation of cerebrospinal fluid (CSF). This increased pressure typically leads to distended scalp veins rather than depressed ones.
B. Sunken anterior fontanels: This is an incorrect choice. The fontanel, also known as the soft spot on an infant's head, may actually bulge rather than appear sunken in cases of hydrocephalus due to increased intracranial pressure.
C.Bulging eyes:In individuals with hydrocephalus, especially infants and young children, bulging eyes can sometimes occur.The increased pressure inside the skull can affect various structures within the brain, including the optic nerve and the muscles that control eye movement. This can lead to a condition called papilledema, where the optic nerve becomes swollen due to the pressure. Papilledema can cause changes in vision and, in some cases, contribute to the appearance of bulging eyes.
D.Separated cranial sutures:The separation of cranial sutures in hydrocephalus occurs due to the increased pressure from the excess CSF. This pressure can cause the bones of the skull to move apart, leading to visible gaps or widening of the sutures. Clinically, this can be observed through imaging studies such as CT scans or MRI.
Correct Answer is A
Explanation
A. Droplet:
Pertussis is primarily transmitted through respiratory droplets when an infected person coughs or sneezes. Droplet precautions involve placing the child in a private room or with another child with the same infection. Healthcare workers should wear a mask or respirator when entering the room to protect against droplet transmission.
B. Contact:
Contact precautions are used for infections that can be spread by direct or indirect contact with the patient or their environment. Pertussis is not typically spread through contact with contaminated surfaces or objects.
C. Airborne:
Airborne precautions are used for infections that are transmitted through small droplet nuclei that remain in the air for long periods. Pertussis is primarily transmitted through larger respiratory droplets rather than tiny airborne particles.
D. Protective environment:
Protective environment precautions are used for patients who have weakened immune systems, such as those undergoing bone marrow transplants. These precautions are not applicable for a child with pertussis.
