Correct Answer is B
Explanation
Prevent infection of the eyes from vaginal bacteria. This is because some newborns can be exposed to bacteria such as gonorrhea or chlamydia during delivery, which can cause a serious eye infection called gonococcal ophthalmia neonatorum (GON). Applying an antibiotic ointment such as erythromycin or ilotycin can prevent GON and other less severe eye infections by killing the bacteria.
Choice A is not correct because the umbilical cord does not need antibiotic ointment to prevent infection. It should be kept clean and dry until it falls off naturally.
Choice C is not correct because the tear ducts are not affected by vaginal bacteria. They are small tubes that drain tears from the eyes to the nose.
Choice D is not correct because the urethra is not a common site of infection for newborns. The urethra is the tube that carries urine from the bladder to the outside of the body.
Correct Answer is A
Explanation
This action helps to prevent cold stress. This is because cold stress is a condition where the newborn's core temperature drops below 36.5°C and they use energy and oxygen to generate warmth. This can lead to hypoglycemia, metabolic acidosis, hypoxia, and an increased risk of infection.
Placing the newborn under a radiant warmer provides thermal stability and prevents heat loss by radiation.
Choice B is wrong because thermogenesis is the process of heat production, not a complication.
Choice C is wrong because shivering is a mechanism of heat production in adults, not in newborns.
Choice D is wrong because brown fat production is a normal feature of newborns that helps them generate heat by lipolysis.
