- A. Hand the doctor another pair of gloves.
- B. Tell the doctor that he has contaminated his gloves.
- C. Say nothing because the client will be placed on prophylactic antibiotics.

The client is becoming increasingly restless and has been given IV morphine every 2 hours for severe pain. Respirations are 28/min and shallow. Which arterial blood gas results best indicate that the client is in acute respiratory failure and needs immediate intervention?
- A. PaO2 49 mm Hg (6.5 kPa), PaCO2 60 mm Hg (8.0 kPa)

The nurse is caring for a client who has a hip fracture and is placed in Buck traction. Which of the following actions should the nurse take? Select all that apply.
- A. Place the client on the affected side.
