A nurse is assisting with the care of an infant who has an upper respiratory infection and requires continuous oxygen saturation monitoring. On which of the following sites should the nurse plan to place the sensor? (You will find hot spots to select in the artwork below. Select only the hot spot that corresponds to your answer.)

A. Toe: In infants, the toes are often the preferred site for pulse oximetry as they have good perfusion and can provide accurate readings without causing discomfort. This site is commonly used for infants who are unable to tolerate sensors on their fingers or ears. B. Finger: The fingers are not typically used in infants, especially in those who are under 1 year of age, because they may not provide a consistent or accurate reading due to smaller, less developed capillaries and possible movement during the procedure. C. Ear lobe: While the ear lobe can be used in older children and adults, it is not the best choice for infants, especially those with respiratory distress, as it might not provide a reliable reading due to the small size and mobility of the earlobe.
