What is the best location to position the pulse oximeter on an active infant in their crib?

• A. Index finger
• B. Great toe
• C. Wrist
• D. Forehead

Answer: (B)

Placing the pulse oximeter on the great toe of an active infant is the best option for several reasons. The great toe typically provides a more stable and reliable measurement of oxygen saturation levels in infants, as their fingers may be less accessible or mobile during activity. Additionally, the toe is often less prone to movement artifacts caused by the infant’s natural wriggling or movement, leading to more accurate readings. In contrast, using the index finger, wrist, or forehead may lead to unreliable readings due to the potential for movement interference or inadequate blood flow. The fingers might not stay still, and the wrist might be less effective due to the smaller surface area and possible twisting motions. When measuring vital signs in infants, choosing a site that reduces the impact of movement is crucial, making the great toe the optimal choice in this scenario.
