Question

The nurse needs to apply oxygen to a patient who has a precise oxygen level prescribed. Which of the following oxygen-delivery systems should the nurse select to administer the oxygen to the patient?

A) Nasal cannula
B) Venturi mask
C) Simple face mask without inflated reservoir bag
D) Plastic face mask with inflated reservoir bag

Answer 1

The nurse should use a Venturi mask to deliver a precise oxygen level to the patient. It is designed for controlled delivery by mixing it with room air for precise concentrations.

Step-by-step explanation:

To administer oxygen to a patient with a precise oxygen level prescribed, the nurse should select the Venturi mask. This system is specifically designed to deliver a controlled amount of oxygen by mixing it with room air to provide the patient with a precise oxygen concentration. Other devices such as a Nasal cannula or a Simple face mask without inflated reservoir bag deliver less precise concentrations, and a Plastic face mask with inflated reservoir bag is typically reserved for higher concentrations of oxygen but with less precision than a Venturi mask.
