A nurse in a provider's office is assessing a client who has AIDS. The nurse notes that the client has multiple and widespread raised, purplish- brown skin lesions. The nurse should recognize that these findings indicate which of the following conditions?
Kaposi's sarcoma
Basal cell carcinoma
Actinic keratosis
Toxic epidermal necrosis
The Correct Answer is A
The lesions are caused by human herpesvirus 8 and can appear anywhere on the body, but are more common on the face, trunk, and extremities. The other conditions are not associated with AIDS or immunosuppression.

Correct Answer is B
Explanation
This is because the recommended tidal volume for mechanical ventilation is 6 to 8 mL/kg of ideal body weight. Therefore, for a client who has an ideal weight of 60 kg, the tidal volume should be between 360 and 480 mL. A tidal volume that is too high or too low can cause lung injury or hypoventilation.
Correct Answer is C
Explanation
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.
