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

Answer and Explanation

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

Explanation

Pyrazinamide is a medication used to treat tuberculosis that can cause renal damage and crystal formation in the urine if not adequately hydrated. The client should also avoid alcohol and have regular liver function tests while taking this medication. Isoniazid should not be taken with antacids, as they can decrease its absorption and effectiveness. Sputum cultures are expected to be negative after 2 months of therapy, not 6 months. Providing a sputum specimen every 2 weeks is not an instruction for the client, but a part of the monitoring process by the health care team.

A. Practice effective hand hygiene. B. Avoid serving raw foods. C. Avoid eating at fast food restaurants D. Wear barrier protection during vaginal intercourse.

Correct Answer is ["A","B"]

Explanation

Hepatitis A is an acute viral infection that affects the liver and is transmitted by fecal-oral route. It can be spread by contaminated food or water, or by close contact with an infected person. Practicing effective hand hygiene can reduce the risk of ingesting or spreading the virus. Avoiding serving raw foods, especially shellfish, can prevent exposure to contaminated food sources.
