What should the nurse suspect a patient is developing when he is observed holding his Bible 6 inches from his face and turns his head to read out of the corner of his eyes?

A. Elevation of urine specific gravity

This may indicate concentration of urine due to dehydration but is not an expected age-related change.

B. Dry oral mucus membranes

Could suggest dehydration but not an expected normal change; should be evaluated.

C. Poor skin turgor over the sternum

Skin elasticity declines with age, but this makes turgor a less reliable indicator, not necessarily a normal sign of dehydration.

D. Decreased creatinine clearance

Normal with aging due to reduced renal function, even if serum creatinine appears normal due to lower muscle mass.

A. They are reluctant to get flu and pneumonia vaccinations: While some older adults may be hesitant, this is not the primary reason respiratory care is emphasized.

B. Decreased activity due to aging lowers oxygenation: Decreased activity can affect oxygenation, but it's not the most direct or major reason respiratory care is crucial.

C. Increased demands on the aging body increase risks of infection: Although aging increases susceptibility to infections, this is too broad and not specific to respiratory care.

D. Chronic pulmonary disease is the third leading cause of death in older adults: This is the most compelling and specific reason; chronic respiratory diseases significantly impact morbidity and mortality in the elderly, making respiratory care a priority.
