What is the recommended way to determine if a baby requires supplemental oxygen in the delivery room? assess the color of the baby's hands and feet. assess the color of the baby's chest and abdomen, and monitor for central cyanosis. send an arterial blood gas, and evaluate the partial pressure of oxygen. place an oximeter sensor on the baby's right hand or wrist and assess oxygen saturation?

The right answer is to look for cyanosis by determining the color of the baby's chest and abdomen,

Cyanosis refers to the bluish coloration that the skin and mucous membranes take when the blood contains a small amount of oxygen-bound hemoglobin.

When there is little oxygen in the blood, it takes on a dark red color. And when all the vessels (of the whole body or a region of the body) carry low oxygenated blood, then it gives the skin the bluish color characteristic of cyanosis.

Symptoms may be associated with that of cyanosis, depending on what causes it. For example, breathing difficulties, chest pain, fever, heart failure or general fatigue.

measuring light intensity

light meters can be used to measure light intensity. the meter is held at the soil surface and pointed in the direction of the maximum light intensity, and then the meter is read.

errors can be made when measuring light intensity by accidentally shading the light meter. the reliability of the results can be checked by taking many samples.
