Which of the following statements are true of changes in airway clearance mechanisms in older patients?
I.Inflammatory responses decrease.
II.Mucociliary clearance rates are faster.
III.Humoral and cell-mediated immunity decreases.
IV.Respiratory muscles are weakened.

Question

Quizplus · Accepted Answer

Impaired respiratory mechanics and weakened respiratory muscles decrease cough effectiveness. Even in the healthy older population, mucociliary clearance rates are slowed. In addition, inflammatory responses and humoral and cell-mediated immunity decrease with age. All of these factors place the elderly at greater risk for developing pneumonia with any respiratory illness.
