Which newborn reflex elicits the following reaction: Head turns to one side - the way the head is facing, the arm/leg is stretched out while the other is bent?
Tonic neck reflex.
Moro reflex.
Startled reflex.
Babinski reflex.
The Correct Answer is A
Choice A reason:
The tonic neck reflex, also called the fencing posture, occurs when a baby's head is turned to one side. The arm and leg on that side stretch out, while the opposite arm and leg bend up at the elbow. This reflex lasts until the baby is about 5 to 7 months old. This reflex matches the description of the question.
Choice B reason:
The Moro reflex, also called the startle reflex, is the baby's reaction to being startled. The cause is often a loud sound, a sudden movement, or even their own cry. As an adult, you may jump or gasp when you are startled. A baby will throw back their head, extend their arms and legs, cry, then pull their arms and legs back in. This reflex does not match the description of the question.
Choice C reason:
The startled reflex is not a distinct reflex in newborns. It is another name for the Moro reflex, which is explained.

Correct Answer is C
Explanation
The correct answer is: c. The lungs of a baby delivered by cesarean section may sound moist for 24 hours after birth.
Choice A reason:
If this baby was born vaginally, it could indicate a pneumothorax.
A pneumothorax occurs when air leaks into the space between the lung and chest wall, causing the lung to collapse. This condition can happen in newborns, especially those with underlying lung issues or those who have undergone mechanical ventilation However, moist lung sounds in a newborn are not typically indicative of a pneumothorax. Pneumothorax is more likely to present with symptoms such as rapid breathing, grunting, and cyanosis.
Choice B reason:
The neonate must have aspirated surfactant.
Surfactant aspiration is not a common cause of moist lung sounds. Surfactant is a substance that helps keep the lungs’ air sacs open and is crucial for proper lung function. Aspiration of surfactant is not a typical diagnosis and would not usually result in moist lung sounds. Instead, surfactant deficiency or dysfunction can lead to respiratory distress syndrome, which presents differently.
Choice C reason:
The lungs of a baby delivered by cesarean section may sound moist for 24 hours after birth.
Babies born via cesarean section often have moist lung sounds because they do not experience the compression of the chest that occurs during vaginal delivery, which helps expel fluid from the lungs. This retained fluid can cause moist lung sounds, which typically resolve within the first 24 hours after birth. This is a normal finding and does not usually indicate a serious problem.
Choice D reason:
The nurse should notify the pediatrician stat for this emergency situation.
While it is always important to monitor newborns closely, moist lung sounds alone in a baby born via cesarean section are not typically an emergency. This finding is usually due to retained fluid in the lungs, which is expected to clear within the first day of life. Immediate notification of the pediatrician is not necessary unless the baby shows other signs of respiratory distress or other concerning symptoms.
Correct Answer is A
Explanation
Choice A reason:
Uteroplacental insufficiency is a condition where the placenta cannot deliver enough oxygen and nutrients to the fetus. This can cause fetal hypoxia and distress, which can be detected by late decelerations on the fetal heart rate monitor. Late decelerations are defined as a decrease in the fetal heart rate that begins after the peak of the contraction and returns to baseline after the contraction ends. This indicates that the fetus is not tolerating the reduced blood flow during the contractions and needs immediate intervention. • Choice B reason:
Umbilical cord compression is a condition where the umbilical cord is squeezed or twisted, reducing the blood flow and oxygen to the fetus. This can cause variable decelerations on the fetal heart rate monitor. Variable decelerations are defined as a decrease in the fetal heart rate that varies in timing, shape, and duration, and may or may not be associated with contractions. This indicates that the fetus is experiencing intermittent or sustained cord compression and may need repositioning or other interventions. • Choice C reason:
Maternal bradycardia is a condition where the mother's heart rate is slower than normal, usually less than 60 beats per minute. This can cause reduced blood flow and oxygen to the placenta and the fetus, but it does not cause late decelerations on the fetal heart rate monitor. Maternal bradycardia can be caused by various factors, such as medications, hypothermia, hypothyroidism, or vagal stimulation. It may need treatment depending on the cause and severity. • Choice D reason:
Fetal head compression is a condition where the fetal head is pressed against the cervix or the pelvic floor during labor, stimulating the vagus nerve and slowing down the fetal heart rate. This can cause early decelerations on the fetal heart rate monitor. Early decelerations are defined as a decrease in the fetal heart rate that begins with the onset of the contraction and returns to baseline with the end of the contraction. This indicates that the fetus is descending in the birth canal and is usually a normal and benign finding.
