A parent comments that her infant has had several ear infections in the past few months. Why are infants more susceptible to otitis media?
Infants are in a supine or prone position most of the time.
Sucking on a nipple creates middle ear pressure.
The Eustachian tube is short, straight, and wide.
Sucking on a nipple creates middle ear pressure.
The Correct Answer is C
C. The Eustachian tube in infants is shorter, straighter, and wider compared to adults. This anatomy makes it easier for bacteria or viruses from the nasopharynx to travel up the Eustachian tube and infect the middle ear, contributing to the increased susceptibility to otitis media.
A. Infants spend a significant amount of time lying down, whether in a supine (on their backs) or prone (on their stomachs) position. However, this does not increase the risk of otitis media
B. Sucking on a nipple does create pressure changes in the middle ear but it's not the primary reason infants are more susceptible to otitis media.
D. Sucking on a nipple does create pressure changes in the middle ear but it's not the primary reason infants are more susceptible to otitis media

Correct Answer is B
Explanation
The nurse should ensure that the rope knots are positioned away from the pulleys to prevent interference with the traction mechanism. Proper alignment of the rope and pulleys ensures smooth traction application and prevents accidental slippage or dislodgment of the traction weights.
A. Buck's traction typically does not involve pin sites. It involves the application of traction to the affected limb using a boot or traction tape. Antibiotic ointment is not typically applied to the skin under Buck's traction unless there are specific wounds or abrasions that require treatment.
C. Ensuring the child's feet are against the footboard is not applicable to Buck's traction, which does not require the feet to be against a footboard.
D. There is typically no need to reduce a child's fluid intake solely because they are in Buck's traction for Legg-Calve-Perthes disease. Adequate hydration is essential for overall health and healing, and fluid restriction is not indicated unless there are specific medical reasons for doing so.
Correct Answer is B
Explanation
B. Reye's syndrome is characterized by swelling of the brain (cerebral edema), which can lead to increased intracranial pressure (ICP). Monitoring for signs of increased ICP, such as changes in level of consciousness, headache, vomiting, and altered pupil size and reactivity, is crucial for early detection and intervention to prevent neurological deterioration.
A. Reye's syndrome primarily affects the liver and brain, leading to liver dysfunction and encephalopathy. While renal involvement can occur in some cases, the priority complication typically relates to liver dysfunction and neurological manifestations rather than renal impairment.
C. Hyperglycemia may be present due to liver dysfunction and altered glucose metabolism, but it is not the primary concern compared to neurological complications and hepatic failure.
D. Reye's syndrome is not caused by a bacterial infection; it is typically associated with viral illnesses, particularly influenza and varicella (chickenpox).
