Answer to Question 1

B, D
Flow rates for a nasal cannula are 1 to 6 L/min, and flow rates for an oxymizer are 1 to 15 L/min, so 2 L/min is appropriate for either device. Flow rates for a simple face mask are 5 to 8 L/min to prevent rebreathing of CO2 . Flow rates for a Venturi mask are 4 to 12 L/min, and a specific rate is necessary to deliver a specific FiO2 .

Answer to Question 2

C, D
The Z-track method is recommended for IM injections. The Z-track technique, which pulls the skin laterally before injection, prevents leakage of medication into subcutaneous tissue, seals medication in the muscle, and minimizes irritation.
