A nurse is providing discharge instructions to the parent of a 10-year-old child following a cardiac catheterization. Which of the following instructions should the nurse include?

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.

When caring for a child with acute appendicitis, the nurse should anticipate an elevated white blood cell count (WBC) in the laboratory values. A high WBC count is a common finding in acute appendicitis, as it indicates an inflammatory response and infection in the body. The body's immune system responds to the inflammation caused by the infected appendix, leading to an increase in WBCs to fight off the infection.
The other options are not necessarily specific to acute appendicitis:
A. RBC 4.2 million/mm³: The red blood cell count (RBC) measures the number of red blood cells in the bloodstream. This value may be within the normal range, but it is not the primary marker for diagnosing or monitoring acute appendicitis.
B. Lymphocytes 3,000/mm3: Lymphocytes are a type of white blood cell involved in the body's immune response. While changes in lymphocyte levels can occur during inflammation, it is not the primary marker for diagnosing or monitoring acute appendicitis.
C. Neutrophils 3.000/mm³: Neutrophils are a type of white blood cell that increases in response to infection and inflammation. However, the absolute neutrophil count is not as relevant as the overall WBC count in determining the presence and severity of acute appendicitis.
