The nervous parent asks when the big "soft spot" (anterior fontanel) will be closed. The nurse's most informative response would be

A. Alertness as such weight loss is not expected: This response may unnecessarily alarm the mother when, in fact, some weight loss in the early days is normal.

B. Reassurance as this is a normal weight loss.

It is normal for newborns to lose some weight during the first few days of life. The loss is often related to fluid loss, changes in feeding patterns, and initial adjustment to life outside the womb. A loss of one-half pound in a 2-day-old neonate is generally considered within the normal range. It's important for the nurse to reassure the new mother that this weight loss is expected and not a cause for alarm. Newborns typically start to regain their birth weight within a week or two. This reassurance can help ease the mother's distress and anxiety.

C. Alarm as this is a drastic weight loss: Characterizing this weight loss as "drastic" is not accurate or helpful and would likely increase the mother's anxiety.

D. Concern as this may be an indicator of inadequate nutrition: Jumping to the conclusion of inadequate nutrition without further assessment and evidence is premature and may unnecessarily worry the mother. It's important to start with reassurance and then investigate if there are concerns about nutrition.

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.
