A nurse receives a call from a parent of a child who has von Willebrand disease and has had a nosebleed. Which of the following instructions should the nurse give to the parent?

Cystic fibrosis (CF) is a genetic disorder that affects the production and function of certain glands, particularly those that produce mucus and sweat. One of the key aspects of CF management is addressing the pancreatic insufficiency that occurs in many individuals with CF. Due to the impairment of the pancreas, children with CF may have difficulty digesting food properly, especially fats. This can lead to malabsorption of nutrients, poor weight gain, and other nutritional deficiencies.

Pancreatic enzyme replacement therapy is a crucial part of CF management. Pancreatic enzymes are prescribed to help the child digest and absorb essential nutrients, especially fats. The enzymes are typically given with each meal and snack to aid in the breakdown and absorption of nutrients.

The other options are not correct:

A. "We will restrict the amount of salt in our child's food."

Sodium restriction is generally not a focus in CF management unless there are specific indications for it. CF patients may have increased salt losses in sweat, but dietary sodium restriction is not a primary aspect of their care.

B. "I will limit my child's fluid intake."

Fluid intake is important for children with CF to maintain hydration and prevent dehydration. There is no specific need to limit fluid intake unless there are individualized medical reasons for doing so.

C. "I will prepare low-fat meals with limited protein for my child."

Children with CF often require a high-calorie, high-protein diet to maintain adequate nutrition and growth. Restricting fat and protein intake is not typically recommended, as these nutrients are essential for a child's development and well-being. Instead, pancreatic enzymes are used to aid in the digestion and absorption of fats and other nutrients.

Consuming a large amount of milk, such as a quart a day, can lead to iron deficiency anemia in toddlers. Milk is a poor source of iron, and excessive milk intake can displace other iron-rich foods from the toddler's diet.

Iron deficiency anemia occurs when the body lacks sufficient iron to produce enough hemoglobin, which is essential for oxygen transport in the blood. Toddlers are particularly vulnerable to iron deficiency anemia because they have increased iron needs for growth and development.

Option A (Obesity) and option B (Diabetes mellitus) are not directly related to the toddler's milk consumption. Obesity may be a concern if the child consumes excessive calories overall, but it is not specifically associated with milk intake. Similarly, diabetes mellitus is not directly related to milk consumption.

Option D (Rickets) is caused by a deficiency of vitamin D, not iron. Rickets results in weakened and deformed bones, and it is usually associated with inadequate sunlight exposure and insufficient dietary vitamin D. While milk is often fortified with vitamin D, excessive milk intake can displace other vitamin D sources in the diet and contribute to an increased risk of rickets, but the primary concern with excessive milk intake is iron deficiency anemia.
