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?

-Water-soluble vitamins: Children with cystic fibrosis often have deficiencies in fat-soluble vitamins (A, D, E, and K) due to malabsorption related to pancreatic insufficiency. Supplementing with water-soluble vitamins is not typically indicated as they are not affected by pancreatic insufficiency.

-Dornase alfa: Dornase alfa is a recombinant human deoxyribonuclease enzyme that helps to thin and break down the thick, tenacious mucus in the airways of patients with cystic fibrosis. It is commonly prescribed to improve respiratory symptoms such as wheezing, rhonchi, and dyspnea.

-Acetaminophen: Acetaminophen may be prescribed for pain or fever relief, but it is not specific to cystic fibrosis management. However, it may be used to alleviate symptoms such as headache or discomfort associated with cystic fibrosis exacerbations.

- Pancreatic Apase: Pancreatic enzymes (e.g., pancreatic lipase, protease, and amylase) are essential for digestion and absorption of nutrients in individuals with cystic fibrosis-associated pancreatic insufficiency. Pancreatic enzyme replacement therapy (PERT) with pancreatic Apase supplements is crucial for improving nutrient absorption and preventing malnutrition.

- Meperidine is an opioid analgesic that is not typically used in the management of cystic fibrosis. While pain management may be necessary for some patients with cystic fibrosis, opioids are generally not recommended due to concerns about respiratory depression and addiction potential.

A. Unable to roll from back to abdomen. Incorrect. Many infants do not roll over until closer to 6 months old, so this is not a concerning finding at 5 months.

B. Absent grasp reflex. Incorrect. The grasp reflex typically disappears around 4 to 6 months of age, so its absence is normal at this stage.

C. Unable to hold a bottle. Incorrect. Holding a bottle can vary widely, and many 5-month-olds do not yet have this skill.

D. Exhibits head lag when pulled to a sitting position. Correct. By 5 months, most infants should have sufficient neck muscle control to not exhibit head lag. Persistent head lag could indicate a developmental delay or neurological problem.
