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 D
Explanation
D. The aim is to focus on the child's strengths and abilities while addressing limitations and challenges associated with the condition. This approach emphasizes maximizing the child's potential for development, independence, and participation in daily activities, education, and social interactions, while also providing support and resources to address any limitations or barriers they may encounter.
A. Another goal of treatment and care is to maximize the child's functional abilities by improving muscle control, coordination, and mobility through various therapies, such as physical therapy, occupational therapy, and speech therapy. However, this is not the primary goal.
B. Cerebral palsy is a neurological condition caused by damage to the developing brain, often occurring before birth. While efforts to prevent cerebral palsy are important, once the condition has developed, the focus shifts to managing symptoms and optimizing the child's functioning rather than eliminating the cause.
C. Emotional well-being is an important aspect of overall health for children with cerebral palsy but it is not typically the primary goal of care. Emotional disturbances may occur in some children with cerebral palsy due to various factors such as coping with the challenges of the condition, social interactions, or other comorbidities, but the primary focus of the care plan is usually on addressing physical and functional impairments.
Correct Answer is A
Explanation
A. Amblyopia occurs when one eye has weaker vision than the other due to abnormal visual development early in life. Patching the good eye helps to encourage the brain to rely more on the weaker eye, stimulating its visual development. This treatment aims to improve vision in the affected eye and restore visual acuity.
B. Patching the affected eye is not a common treatment for amblyopia. In fact, patching the affected eye would further decrease visual input to that eye and could potentially exacerbate the condition. The goal of treatment for amblyopia is to strengthen the weaker eye by encouraging its use, rather than resting it.
C. Corticosteroids are not typically used to treat amblyopia unless there is a specific underlying condition causing inflammation of the optic nerve. Amblyopia is primarily a developmental issue rather than an inflammatory condition, so corticosteroids would not be the first-line treatment for this condition.
D. This is not a common treatment for amblyopia. In fact, the goal of treatment for amblyopia is to improve vision in the affected eye, not to intentionally blur the vision in the good eye. Glasses prescribed for amblyopia typically aim to correct refractive errors (such as nearsightedness, farsightedness, or astigmatism) and provide clear vision to both eyes, which can help support visual development in the weaker eye.
