A school nurse is using the Weber test to check a child's hearing acuity. Which of the following actions should the nurse take?
Measure the amount of time the child can hear the sound
Obtain a tympanogram reading prior to initiating the test
Place a vibrating tuning fork on the top of the child's head
Hold a vibrating tuning fork 1 to 2 cm (0.4 to 0.8 in) from the child's ears
The Correct Answer is C
Choice A reason: The Weber test assesses lateralization of sound, not duration. Measuring time is irrelevant to this test.
Choice B reason: Tympanometry is a separate diagnostic tool and not required before performing the Weber test.
Choice C reason: Placing the vibrating tuning fork on the top of the head allows sound to travel through bone conduction, helping identify unilateral hearing loss.
Choice D reason: Holding the fork near the ears is part of the Rinne test, not the Weber test.

Correct Answer is A
Explanation
Choice A reason: Irritability is a common finding in newborns exposed to cocaine in utero. These infants may be difficult to console and exhibit high-pitched crying.
Choice B reason: Cocaine-exposed infants often have hypertonicity rather than hypotonicity due to central nervous system stimulation.
Choice C reason: Increased head circumference is not a typical finding. Head size may be normal or reduced depending on growth restriction.
Choice D reason: These infants often have heightened responses, not decreased auditory startle. Hyperreactivity is more common.
Correct Answer is A
Explanation
Choice A reason: Applying petroleum jelly with each diaper change protects the healing site from friction and prevents the diaper from sticking to the wound. This promotes comfort and proper healing.
Choice B reason: Alcohol is too harsh for the healing circumcision site and can cause irritation and delayed healing. Gentle cleansing with warm water is preferred.
Choice C reason: Using the diaper to apply pressure is not recommended. Gentle handling is essential to avoid trauma to the healing tissue.
Choice D reason: Yellow drainage is part of the normal healing process and should not be wiped off. Removing it can disrupt healing and increase the risk of infection.
