The child with CF is prescribed vitamin A supplements. Which finding by the clinic nurse indicates that the vitamin has been effective?
Correct Answer: A
Rationale: A: A water-miscible form of vitamin A is given in children diagnosed with CF because the uptake of the fat-soluble vitamins is decreased. One of the functions of vitamin A is to keep epithelial tissue healthy by aiding the differentiation of specialty cells. B: Other treatments for CF, such as bronchodilators and recombinant human deoxyribonuclease dornase alfa (Pulmozyme), decrease the viscosity of secretions. C: Vitamin K, another fat-soluble vitamin administered in CF, increases coagulation. D: Vitamin A has no effect on pancreatic enzyme absorption.
