Correct Answer is D

Explanation

A. Expectorants do not suppress the urge to cough. Instead, they work by increasing the volume of respiratory secretions, making them thinner and easier to expectorate.
B. Expectorants do not have anti-inflammatory properties. They do not reduce inflammation in the airways.
C. Expectorants actually do the opposite. They increase the volume of respiratory secretions, making them thinner and easier to expectorate.
D. Expectorants work by stimulating the production of respiratory secretions, making them thinner and easier to cough up. This helps to clear the airways and relieve congestion.

A. The patient's Spo2 is 97% on 2L NC B. The patient appears comfortable C. The patient is able to move out of bed without difficulty D. The patient is coughing up copious white sputum

Correct Answer is A

Explanation

A. An SpO2 (oxygen saturation) level of 97% indicates that the patient is effectively oxygenating. This is an important measure of gas exchange and shows that the interventions to improve oxygenation have been effective, especially when maintained on a low flow of oxygen (2 liters via nasal cannula).
B. While comfort can indicate improvement, it is subjective and does not directly measure the effectiveness of gas exchange. A patient can appear comfortable but still have impaired oxygenation. Therefore, while this finding is positive, it should not be the primary indicator of effective intervention.
C. The ability to move out of bed without difficulty can indicate improved overall physical status and functional mobility, which may result from effective gas exchange. However, this alone does not specifically assess the effectiveness of interventions aimed at gas exchange.
D. This option is not necessarily an indicator of effective interventions for gas exchange. Coughing up copious sputum could indicate ongoing pulmonary issues such as infection or inflammation and does not directly correlate with improved gas exchange.
