A charge nurse is observing a staff nurse who is caring for a child who has pertussis. Which of the following actions by the staff nurse indicates an understanding of infection control practices?

A. Sausage-shaped mass in the upper right abdomen A sausage-shaped mass in the upper right abdomen is indicative of intussusception, not celiac disease.

B. Red-currant, jelly-like stools: Red-currant, jelly-like stools are characteristic of intussusception, not celiac disease.

C. Hematemesis: Hematemesis (vomiting blood) is not a typical symptom of celiac disease. It is more commonly associated with conditions involving gastrointestinal bleeding such as esophageal varices or severe gastritis.

D. Steatorrhea: Steatorrhea (fatty stools) is a common finding in celiac disease due to malabsorption of fats in the intestine. The inability to digest and absorb fat leads to pale, foul-smelling, and bulky stools.

A. "Your child might need to have their tonsils and adenoids removed." Removal of tonsils and adenoids is not typically related to cystic fibrosis management. This statement is not accurate in the context of cystic fibrosis home care.

B. "Your child will take isoniazid for 9 months." Isoniazid is used for the treatment or prevention of tuberculosis, not cystic fibrosis. This statement is not relevant to cystic fibrosis.

C. "Your child will have chest x-rays periodically to monitor for disease reactivation." Periodic chest x-rays are more commonly used to monitor lung infections and complications in cystic fibrosis patients, not specifically for disease reactivation.

D. "Your child should take pancreatic enzymes with meals and snacks." Children with cystic fibrosis often have pancreatic insufficiency, requiring pancreatic enzyme supplements with meals and snacks to aid digestion and nutrient absorption.
