What might the nurse explain as a common treatment for amblyopia?

Patching the good eye to force the brain to use the affected eye

Patching the affected eye to allow the refractory muscles to rest

Using corticosteroids to treat inflammation of the optic nerve

Using glasses that will slightly blur the image for the good eye

Answer and Explanation

The Correct Answer is A

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.

Correct Answer is C

Explanation

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

A. Reassure the mother that the tubes will not fall out. B. Take the child to an emergency department. C. Gently reinsert the tubes. D. Call the health care clinic to report that the tubes have fallen out.

Correct Answer is D

Explanation

D. If the tympanostomy tubes fall out, the parent should contact the healthcare clinic or the healthcare provider who performed the procedure. They can provide guidance on whether the child needs to be seen for an evaluation and potential replacement of the tubes. Reporting the situation allows for appropriate follow-up and management by the healthcare team.

A. Tympanostomy tubes are small tubes inserted into the eardrums to help drain fluid from the middle ear and prevent recurrent ear infections. While they are designed to stay in place for a certain period, it is possible for them to fall out prematurely.

B. It's important for the parent to seek medical advice if the tubes fall out but it may not always require an immediate visit to the emergency department. However, if the child experiences severe pain, bleeding, or signs of infection after the tubes fall out, seeking urgent medical attention may be warranted.

C. Only a healthcare provider should insert or reinsert tympanostomy tubes. Attempting to reinsert the tubes at home without proper training and equipment could cause injury or damage to the ear.
