To prevent heat loss from convection in a newborn, which action by the nurse is best?

The correct answer is: d. Move infant away from blowing fan.

Choice A: Dry the baby after a bath

Drying the baby after a bath is essential to prevent heat loss through evaporation. When a newborn is wet, the water on their skin can evaporate, taking heat away from their body. While this is an important step in maintaining the baby’s temperature, it does not specifically address heat loss through convection.

Choice B: Wrap the baby in warmed blankets

Wrapping the baby in warmed blankets helps prevent heat loss through conduction and radiation. Conduction occurs when the baby comes into contact with a cooler surface, and radiation occurs when the baby loses heat to the surrounding environment. Although this action is beneficial, it does not directly address heat loss through convection.

Choice C: Place the baby in a warmer

Placing the baby in a warmer is an effective way to maintain the baby’s overall body temperature by providing a controlled, warm environment. This action helps prevent heat loss through conduction, radiation, and evaporation. However, it is not the most direct method to prevent heat loss through convection.

Choice D: Move infant away from blowing fan

Moving the infant away from a blowing fan directly addresses and prevents heat loss due to air movement, which is a key factor in convection. Convection occurs when air currents carry heat away from the baby’s body. By moving the baby away from the fan, the nurse can effectively reduce heat loss through this mechanism.

Choice A reason:

Choice A is incorrect because an Apgar score of 7 would not be appropriate for the described condition. An Apgar score of 7-10 is considered normal for a baby at 1 minute after birth. This baby shows positive signs such as a heart rate of 138 bpm, loud vigorous crying, spontaneous movement and flexion of the extremities, and pink skin color except for a bluish color of the hands and feet, which indicate good overall health.

Choice B reason:

Choice B is the correct answer. An Apgar score of 8 is appropriate for the described condition.

The Apgar score evaluates the baby's condition at 1 minute after birth based on five criteria: heart rate, respiratory effort, muscle tone, reflex irritability, and color. Each criterion is scored from 0 to 2, and the scores are summed up to determine the overall Apgar score. In this case, the baby exhibits positive signs in most of the criteria, resulting in an Apgar score of 8.

Choice C reason:

Choice C is incorrect because an Apgar score of 9 would be too high for the baby's condition. While the baby is exhibiting positive signs, there are still some concerns such as the bluish color of the hands and feet, which may indicate some minor circulation issues.

Choice D reason:

Choice D is also incorrect because an Apgar score of 10 is the highest possible score, and it is typically given to babies who exhibit absolutely no signs of distress or health issues at 1 minute after birth. While this baby shows mostly positive signs, the bluish color of the hands and feet suggests that there might be some minor health concerns, justifying an Apgar score of 8.
