A nurse is assessing the reflexes of a term newborn. After placing the newborn in the supine position, which of the following methods should the nurse use to elicit the Moro reflex?
Make a loud noise above the newborn.
Touch the newborn's cheek with a finger.
Tap the newborn's forehead with a finger.
Turn the newborn's head to one side.
The Correct Answer is A
Choice A rationale:
The Moro reflex, also known as the startle reflex, is elicited by making a loud noise above the newborn, causing them to extend their arms and legs and then bringing them back to the body in a hugging motion. This reflex is a normal developmental response in term newborns.
Choice B rationale:
Touching the newborn's cheek with a finger elicits the rooting reflex, where the newborn turns their head toward the stimulus, searching for a nipple or object to suck. It is a different reflex and not the Moro reflex.
Choice C rationale:
Tapping the newborn's forehead with a finger does not elicit any specific reflex. This action is not related to the Moro reflex.
Choice D rationale:
Turning the newborn's head to one side elicits the asymmetric tonic neck reflex (ATNR), not the Moro reflex. In ATNR, when the head is turned to one side, the arm on that side extends while the opposite arm flexes.

Correct Answer is B

Correct Answer is A
Explanation
Choice A rationale:
Vibroacoustic stimulation is an appropriate action to perform during a nonstress test if there are no fetal heart rate accelerations. It involves using sound or vibration to stimulate the fetus, potentially eliciting the desired heart rate accelerations.
Choice B rationale:
Placing the client in the Trendelenburg position is not indicated in this situation. It may not benefit the fetus and is not a standard intervention for nonreactive nonstress test results.
Choice C rationale:
Conducting a vaginal exam is not relevant to the situation described in the question. A nonreactive nonstress test does not require a vaginal exam.
Choice D rationale:
Collecting a specimen for an indirect Coombs test is not necessary for this scenario. The test result would not provide information relevant to the nonreactive nonstress test.
