When assessing a newborn, which is the best method for the nurse to use to elicit the Moro reflex?
Making a loud sound within close range of the newborn.
Firmly stroking the soles of the newborn’s feet with a thumb nail.
Using the newborn’s hands to raise the baby from a supine position without supporting the head.
Holding the newborn in an upright position so that the infant’s feet touch a cool, flat surface.
The Correct Answer is A
The correct answer is choice A. Making a loud sound within close range of the newborn will elicit the Moro reflex, which is an involuntary protective motor response against abrupt disruption of body balance or extremely sudden stimulation. The Moro reflex involves three distinct components: spreading out the arms (abduction), pulling the arms in (adduction), and crying (usually).
Choice B is wrong because firmly stroking the soles of the newborn’s feet with a thumb nail will elicit the Babinski reflex, which is a normal response in infants that involves fanning out and curling of the toes.
Choice C is wrong because using the newborn’s hands to raise the baby from a supine position without supporting the head will elicit the traction response, which is a normal response in infants that involves flexion of the elbows and shoulders.
Choice D is wrong because holding the newborn in an upright position so that the infant’s feet touch a cool, flat surface will elicit the stepping reflex, which is a normal response in infants that involves alternating steps with each foot.

Correct Answer is A
Explanation
The correct answer is choice A: To minimize the patient’s oxygen needs.
A neutral thermal environment is an environment in which a neonate maintains a normal body temperature while minimizing energy expenditure and oxygen consumption.This is important for the wellbeing of neonates, especially those who are preterm or have respiratory insufficiency.
Choice B is wrong because the conversion of glucose to lactic acid is not a desired outcome of a neutral thermal environment.This conversion occurs when there is inadequate oxygen supply to the tissues, resulting in anaerobic metabolism and metabolic acidosis.
Choice C is wrong because the absorption of surfactant from the alveoli is not affected by a neutral thermal environment.
Surfactant is a substance that reduces surface tension and prevents alveolar collapse.It is produced by type II alveolar cells and secreted into the alveoli.
Choice D is wrong because the metabolism of brown fat stores is not a desired outcome of a neutral thermal environment.
Brown fat is a specialized tissue that generates heat by nonshivering thermogenesis in response to cold stress.
It is located in the nape of the neck, between the scapulae, and around the kidneys and adrenals.It increases the metabolic rate and oxygen consumption of neonates.
Correct Answer is D
Explanation
The correct answer is choice D. Presence of human chorionic gonadotropin (hCG) in blood.This is apositive sign of pregnancythat can only be attributed to a fetus.hCG is a hormone produced by the placenta that can be detected in blood or urine tests.
Choice A. Quickening.This is apresumptive sign of pregnancythat is based on the woman’s report of feeling fetal movements in her lower abdomen.This can occur at 16 weeks for second time moms and around 20 weeks for first time moms.However, this sign is not conclusive as other conditions can cause similar sensations.
Choice B. Uterine enlargement.This is aprobable sign of pregnancythat can be observed by the nurse or doctor through palpation.However, this sign does not mean 100% that a baby is growing in the uterus as it can be due to other causes such as fibroids or tumors.
Choice C. Urinary frequency.This is apresumptive sign of pregnancythat is based on the woman’s report of needing to urinate more often than usual.This can be caused by hormonal changes and increased blood volume during pregnancy.However, this sign is not definitive as other conditions such as urinary tract infections or diabetes can also cause frequent urination.
