The C in COPD stands for:

A. Asthma is not typically linked to bedrest. Bedrest can lead to decreased lung expansion and impaired mucus clearance, which may increase the risk of infections like pneumonia, but it does not specifically increase the risk of asthma.
B. When a patient is immobile and unable to get out of bed, mucus can accumulate in the lungs, as normal coughing and deep breathing are reduced. This pooling of mucus provides an ideal environment for bacteria to grow, leading to pneumonia.
C. While supplemental oxygen might be needed for patients with certain respiratory conditions, it is not the primary risk factor for pneumonia in bedrest. In fact, oxygen therapy might be used to treat pneumonia.
D. Hospital-acquired infections, including pneumonia, are a concern, but the primary risk from bedrest is the inability to clear mucus effectively, not the presence of pathogens alone.

A. Waiting 15 minutes after giving the cough syrup is unnecessary. There's typically no reason to delay giving tablets after a liquid medication unless specifically indicated.
B. Giving the cough syrup between the tablets is not an optimal approach, as it could result in potential interactions or interfere with absorption of the medications.
C. Administering the cough syrup first allows the liquid medication to be absorbed more quickly. Afterward, the tablets can be given with water to facilitate swallowing and ensure proper absorption. This order is generally most effective in promoting absorption and preventing interference between the two types of medication.
D. Administering the tablets first may lead to them being coated with the liquid, potentially delaying their absorption and effectiveness.
