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 ["A","D","E"]
Explanation
This is because these medications are antimycobacterial agents that inhibit the growth and replication of Mycobacterium tuberculosis, the bacterium that causes tuberculosis. Acyclovir is an antiviral medication that is used to treat herpes simplex virus infections, and montelukast is a leukotriene receptor antagonist that is used to prevent asthma attacks.
Correct Answer is B
Explanation
This is because sputum culture can identify the presence and type of mycobacteria that cause TB, while other tests can only indicate exposure or infection. Sputum culture results may take several weeks, so treatment should be initiated based on clinical suspicion and other tests.
