Question

a patient has skin that is slightly blue in color. a likely treatment for this person might be

increasing fluids through iv therapy
exposing the patient to more sunlight
giving the patient supplemental oxygen by mask
encouraging the patient to eat more orange colored vegetables (rich in beta carotene)

Explanation:

Skin that is slightly blue in color (cyanosis) often indicates a lack of oxygen in the blood. Supplemental oxygen by mask would help increase the oxygen levels in the blood. Increasing fluids through IV therapy is for hydration issues. Exposing to more sunlight is for vitamin D or certain skin conditions (not related to cyanosis here). Eating more orange - colored vegetables (rich in beta - carotene) can give skin an orange tint (not reverse cyanosis).

Answer:

giving the patient supplemental oxygen by mask
