Answer to Question 1

B, D
A vascular, pulsatile area (e.g., fingertip or earlobe) is needed to detect the degree of change in the transmitted light. Factors that affect light transmission (e.g., sensor movement, fingernail polish) or peripheral arterial pulsations (e.g., hypotension, anemia) also affect the measurement of SpO2 . An awareness of these factors allows for accurate interpretation of abnormal SpO2 measurements. Measuring SpO2 can be conducted intermittently or continuously to assess ongoing therapies.

Answer to Question 2

B
In general, you reposition patients as needed and at least every 2 hours if they are in bed and every 1 hour if they are sitting in a chair.
