  2. less effective cough
  3. immobility
  4. increased pain response
  5. fixed income

Question 2

The nurse is planning a class for nursing assistants. What should the nurse include as causing interference with accurate pulse oximeter readings?
 
  Select all that apply.
  1. external light sources
  2. nail polish
  3. inhalation injuries
  4. arterial pulses
  5. placement on cartilage

Answer to Question 1

Correct Answer: 2, 3
Skeletal muscle strength is lost in the thorax and diaphragm with aging. This contributes to a less effective cough and the ability to remove respiratory secretions. The secretions can pool in the lungs if the patient is not mobile, providing an environment for pneumonia to develop. Respiratory rate does not contribute to the risk of pneumonia. It is a myth that older adults have an increased pain response, and this would not directly contribute to the development of pneumonia. There is no direct correlation between being on a fixed income and developing pneumonia.

Answer to Question 2

Correct Answer: 1, 2
Other sources of light can cause inaccurate readings. Nail polish on finger/toenails can cause inaccurate readings. There is no evidence that inhalation injuries will alter pulse oximeter readings. Arterial pulses have no influence on pulse oximeter readings. The sensor can be placed on the nose or earlobe, which contain cartilage.
