- B. Administer high levels of oxygen to the client
- C. Have the client sign a permit for suctioning

- C. Remove electrical devices from the room where oxygen is in use.

- A. Client reports heavy menstrual cycles

- C. History of deep venous thrombosis
- D. Weight is 186 lb (84.4 kg) and BMI is 31.0 kg/m^2
