A nurse working in the emergency department (ED) is admitting a client. Exhibits The nurse is reviewing the client's medical record. Which of the following conditions should the nurse identify as a risk factor for pneumonia? Select all that apply.

A. COPD: Clients with chronic obstructive pulmonary disease (COPD) are at increased risk for pneumonia due to compromised lung function, chronic inflammation, and decreased mucociliary clearance, making it easier for pathogens to infect the lungs. B. Hypertension: While hypertension is a significant cardiovascular risk factor, it does not directly increase the risk of pneumonia. Therefore, it is not a relevant factor in this case. C. Dermatitis: Dermatitis is a skin condition and does not affect lung function or immunity in a way that would increase the risk of pneumonia. D. Smoking history: Smoking damages the respiratory epithelium and impairs the immune defenses of the lungs, making smokers more susceptible to respiratory infections such as pneumonia. E. Type 2 diabetes mellitus: Diabetes compromises immune function and increases the risk of infections, including pneumonia, due to hyperglycemia impairing neutrophil function and other immune responses. F. Hypothyroidism: While hypothyroidism may cause some general symptoms such as fatigue, it does not directly compromise respiratory function or immunity in a way that increases the risk of pneumonia.
