The nurse explains that the medication Prostaglandin E1 is being given to their child with transposition of the great vessels to:

A. Dress the child in woolen clothes during cold months: Wool can be irritating to the skin and may worsen eczema symptoms. Cotton or soft fabrics are typically better choices.

B. Launder the child's clothing with fabric softener: Fabric softeners often contain chemicals that can irritate the skin. It's best to use fragrance-free and hypoallergenic detergents and skip fabric softeners.

C. Apply a topical corticosteroid ointment to the affected area.

When teaching a parent of a preschooler with eczema, it's essential to provide guidance on appropriate treatments. Applying a topical corticosteroid ointment is an effective approach for managing eczema symptoms. These medications can help reduce inflammation and itching, which are common in eczema. However, it's crucial for the parent to use them as directed by a healthcare provider and not excessively.

D. Give the child a bubble bath every day: Frequent bathing, especially with bubble baths, can dry out the skin and worsen eczema. It's usually better to limit baths and use gentle, fragrance-free cleansers.

A. "The body's response to gluten causes the intestine to become more porous and hang on to more of the fat-soluble vitamins, leading to vitamin toxicity." This answer is not accurate. The issue in celiac disease is malabsorption, not vitamin toxicity.

B. "The body's response to gluten causes damage to the mucosal cells in the intestines leading to absorption problems."

Celiac disease is an autoimmune disorder in which the ingestion of gluten (a protein found in wheat, barley, and rye) leads to damage of the mucosal cells in the small intestine. This damage, in turn, can lead to malabsorption of essential nutrients, including vitamins, minerals, and other important components of the diet. It is important for individuals with celiac disease to avoid gluten-containing foods to prevent ongoing damage to the intestinal mucosa and improve nutrient absorption.

C. "The body's response to consumption of anything containing gluten is to create special cells called villi, which leads to more diarrhea." This statement is not accurate. Celiac disease leads to damage to the villi (finger-like projections) in the small intestine, not the creation of special cells. It can lead to diarrhea but is not the primary cause.

D. "The body's response to gluten causes damage to the mucosal cells, leading to malabsorption of water and hard, constipated stools." This response is not accurate. Celiac disease is more commonly associated with diarrhea and malabsorption, not constipation and malabsorption of water.
