A nurse is assessing a client who has asthma. Which of the following areas should the nurse evaluate as the most reliable indicator of central cyanosis?
Soles of the feet
Ear lobes
Oral mucosa
Conjunctivae
The Correct Answer is C
This is because central cyanosis reflects a decrease in arterial oxygen saturation and is best seen in areas where blood vessels are close to the surface, such as the oral mucosa, tongue, and lips. Peripheral cyanosis, which may be caused by vasoconstriction or poor circulation, can be seen in the soles of the feet, ear lobes, and nail beds, but it does not necessarily indicate hypoxemia.

Correct Answer is ["31.5"]
Explanation
The anterior chest wall and abdomen accounts for 18%, the left upper limb 9 % (4.5% anteriorly and 4.5% posteriorly), and the right upper limb 4.5% (2.25% anteriorly and 2.25% posteriorly).
(18+9+4.5) =31.5%
Correct Answer is ["A","C","D"]
Explanation
These interventions can help prevent complications such as stress ulcers, ventilator-associated pneumonia, and aspiration. Pantoprazole reduces gastric acid secretion and protects the mucosa from erosion. Verifying the ventilator settings ensures that the client is receiving adequate oxygenation and ventilation according to their needs and goals. Elevating the head of the bed reduces the risk of aspiration and improves lung expansion.
