Answer to Question 1

A
When rapid- or short-acting insulin is mixed with intermediate- or long-acting insulin, air should be injected into the intermediate- or long-acting insulin vial first without withdrawal of the medication. Regular insulin is withdrawn first, and then the combined total insulin dose is calculated before the NPH insulin is withdrawn from the vial.

Answer to Question 2

C
C. A nasal cannula is useful for low oxygen concentration for clients with chronic lung disease.
A. The face tent is a shieldlike device that fits under the client's chin and can deliver high levels of oxygen, not suitable for COPD.
B. The face mask fits over the client's mouth and nose and can deliver high levels of oxygen, not suitable for COPD.
D. The nonrebreathing mask delivers high levels of oxygen, not suitable for COPD.
