A decreased respiratory rate is not expected in a client with COPD experiencing dyspnea, as they often have an increased respiratory rate.

Choice B, 'Increased mobility,' is not directly related to an increased risk of infections. Choice C, 'Chronic conditions,' while they can contribute to a weakened immune system, do not directly address the primary risk factor for infections in older adults.
