The pulse oximeter indicates a patient's blood oxygen level is 89. A nurse knows that it is important to
1. Verify the oximeter is placed on a site that has adequate capillary refill.
2. Call the laboratory and order arterial blood gases to get a more accurate oxygen level.
3. Encourage the patient to get out of bed and ambulate more.
4. Let the patient rest quietly to reduce the need for oxygen.

1. Noisy, snoring sounds during respirations.
2. Musical or whistling sounds with respirations.
3. A sonorous wheeze upon inspiration.
4. Sounding like hair being rubbed between the thumb and index fingers.
