The nurse recognizes that adequate nutrition plays an important role in weaning the patient from the ventilator
Which of the following components of a nutritious diet will assist in increasing the strength of the respiratory muscles and should also be approximately 25% of the total daily kilocalories?
A) Simple carbohydrates
B) Fats
C) Protein
D) Complex carbohydrates
Ans: C
Feedback: Adequate protein intake should be approximately 25% of total daily kilocalories, or 1.2 to 1.5 g/kg/day. Adequate protein intake is important in increasing respiratory muscle strength. A high-fat diet may provide as much as 50% of the total daily kilocalories. There is evidence that both limiting carbohydrate intake and providing a carbohydrate-enriched diet are helpful.
