Question

which of the following individuals would be at the greatest risk for bacterial pneumonia?
a. a 90 - year - old grandmother
b. a 30 - year - old teacher
c. a 45 - year - old parent
d. a 20 - year - old college student

Explanation:

Age is a significant risk factor for bacterial pneumonia. Older adults (especially those over 65) have weaker immune systems and may have underlying health conditions or physical changes (like decreased cough reflex) that increase pneumonia risk. Younger individuals (like 20 - 30 - year - olds) generally have stronger immune systems and fewer age - related physical changes that predispose to pneumonia.

Answer:

A. a 90 - year - old grandmother
