A nurse is caring for a child who has Kawasaki disease. Which of the following systems should the nurse monitor in response to this diagnosis?

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.

The nurse should expect to find irritability in an infant who is dehydrated. Dehydration in infants can lead to changes in behavior and irritability due to the imbalance in fluid and electrolytes. Other common signs of dehydration in infants may include:
Poor skin turgor (skin tenting)
Sunken fontanelles (soft spots on the baby's head)
Dry mucous membranes (dry mouth and tongue)
Decreased urine output or concentrated urine
Rapid heart rate (tachycardia)
Increased respiratory rate
Sunken eyes
Decreased tears when crying

B. Tetany is a condition characterized by involuntary muscle contractions and is more commonly associated with hypocalcemia (low calcium levels) rather than dehydration.
C. A slow, bounding pulse is not typically associated with dehydration. Dehydration often leads to a rapid heart rate (tachycardia) as the body attempts to compensate for the loss of fluid.
D. Decreased temperature is not a typical finding in dehydration. Dehydration can lead to fever in some cases due to an underlying infection, but it does not cause a decrease in body temperature on its own.
