Answer to Question 1

A
Excessive calorie intake can raise PaCO2 sufficiently to make it difficult to wean a patient from the ventilator. A balanced regimen with both lipids and carbohydrates providing the nonprotein calories is optimal for patients with respiratory compromise, and these patients need to be reassessed continually to ensure that caloric intake is not excessive.

Answer to Question 2

A, B, E
Malcolm Knowles described these principles of adult learning in a model known as andragogy. Adult learning theory stresses concepts of individualism, self-assessment, self-direction, motivation, experience, and autonomy.
