The nurse is performing an assessment of a client admitted to the emergency department with respiratory distress. The nurse should carefully inspect which part of the body to identify central cyanosis?
Oral mucosa
Palms
Sclera
Nail beds
The Correct Answer is A
A. Oral mucosa is correct. Central cyanosis occurs when oxygen saturation is significantly reduced and is best assessed in areas with rich vascular supply, such as the oral mucosa, lips, and tongue.
B. Palms are incorrect because peripheral cyanosis (often due to cold exposure or poor circulation) can cause blue-tinged extremities, but this does not indicate central cyanosis.
C. Sclera is incorrect because cyanosis does not affect the sclera; however, jaundice does.
D. Nail beds are incorrect because, like the palms, they are more indicative of peripheral cyanosis, which can result from localized poor perfusion rather than central oxygenation problems.

Correct Answer is C
Explanation
A. A fluid deficit may cause tachycardia and hypotension, but it does not directly cause diminished lung sounds.
B. Adventitious sounds (wheezes, crackles, rhonchi, etc.) are absent in this case. Diminished breath sounds suggest poor airflow, not abnormal sounds.
C. Hyperinflation of the lungs is correct. In conditions like chronic obstructive pulmonary disease (COPD) or emphysema, lung expansion is limited, leading to diminished breath sounds in all lung fields due to air trapping. The oxygen saturation of 92% is consistent with chronic lung disease.
D. Pectus carinatum (protrusion of the sternum) is a congenital deformity that does not cause diminished breath sounds.
Correct Answer is A
Explanation
A. Having the client cough, then listening again is correct. Sometimes wheezing can be due to mucus or secretions in the airways, and coughing can help clear them. If wheezing persists, further assessment and interventions may be needed.
B. Teaching pursed-lip breathing is beneficial for chronic obstructive pulmonary disease (COPD) patients but is not the first action in an acute assessment.
C. Checking O₂ saturation and applying O₂ is important but not the first step. Oxygen therapy is not indicated unless there is evidence of hypoxia.
D. Administering a nebulizer treatment should only be done if wheezing persists and is causing respiratory distress, but the nurse should first confirm that the wheezing is not due to mucus plugging, which may resolve with coughing.
