Answer to Question 1

D
Feedback:
The cell-mediated immune response tends to decrease in effectiveness with age. The total number of immunoglobulins, T cells, and B cells does not change and sensitivity to cutaneous introduction of pathogens decreases, not increases.

Answer to Question 2

A
Encourage postural drainage. Suction the patient as needed and provide assistance in turning, coughing, and deep breathing every 2 hours. Assist with chest physiotherapy.
