What factor increases the risk of respiratory infection for older adults?

A. Develop close relationships with other people; to learn and experience love

This is associated with young adulthood (Erikson’s stage of Intimacy vs. Isolation), not old age.

B. Establish trusting relationships with other people

This occurs in infancy (Erikson’s stage of Trust vs. Mistrust), not in older adulthood.

C. Find a vocation or hobby where the individual can help others or in some way contribute to society

This is part of middle adulthood (Erikson’s stage of Generativity vs. Stagnation), not late adulthood.

D. Review life and gain a feeling of accomplishment or fulfillment

According to Erikson’s developmental theory, the key task of older adulthood is Ego Integrity vs. Despair, which involves life review and achieving a sense of fulfillment.

A. Decreased secretion of saliva

This is not a normal part of aging; if present, it's often due to medications or illness.

B. Increased acidity of saliva

Salivary composition doesn’t change significantly with age; this is not a recognized normal change.

C. Decreased gastric emptying

Aging can slow down GI motility, leading to delayed gastric emptying, which can contribute to fullness or indigestion.

D. Increased peristalsis

GI peristalsis slows with age, increasing the risk of constipation, not increasing motility.
