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
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 D
Explanation
D. This is the correct action to take. A neurovascular check involves assessing the circulation, sensation, and movement in the affected limb. This check helps monitor for complications such as impaired circulation, nerve damage, or compartment syndrome, which can occur after the application of a plaster cast. Regular neurovascular checks are essential for early detection of any issues and appropriate intervention if necessary.
A. Using a hair dryer on a hot setting can cause burns to the skin under the cast. It can also cause the cast material to heat up and potentially cause discomfort or injury to the patient.
B. It's essential to follow the healthcare provider's instructions regarding weight-bearing restrictions, but completely discouraging ambulation can lead to complications such as muscle atrophy, decreased circulation, and increased risk of blood clots.
C. Keeping the client's leg in a dependent position means positioning it lower than the heart. This can increase swelling and exacerbate pain, potentially leading to complications such as compartment syndrome.
Correct Answer is ["A","B","D"]
Explanation
A. Wheezing. Cystic fibrosis can cause airway obstruction due to thickened mucus, leading to wheezing and difficulty breathing, especially during respiratory infections or exacerbations.
B. A barrel-shaped chest is often seen in advanced stages of cystic fibrosis. It results from hyperinflation of the lungs due to air trapping, chronic lung disease, and repeated respiratory infections. The chest appears rounded and enlarged, similar to the shape of a barrel.
D. Clubbing of fingers and toes is a common finding in cystic fibrosis. It is caused by chronic hypoxia and inadequate oxygenation of tissues, leading to changes in the nail beds and fingertips. Clubbing typically develops over time in individuals with chronic respiratory conditions, including cystic fibrosis.
C. Thin, watery mucous is not expected in cystic fibrosis. Instead, cystic fibrosis is characterized by thick, sticky mucus due to dysfunction of the exocrine glands, leading to blockages in the airways, pancreas, and other organs.
E. Rapid growth spurts are not typically associated with cystic fibrosis. In fact, children with cystic fibrosis may experience growth failure or delayed growth due to malabsorption of nutrients, chronic illness, and increased energy expenditure.
