The mother visits her infant in the nursery.
The nurse shows the mother how to place her finger in the palm of the baby’s hand so that the baby will squeeze her finger.This behavior on the nurse’s part reflects an understanding of which principle?

The correct answer is choice C. When the neonate responds to the mother by some signal, attachment behavior is stimulated in the mother.This is based on therooting reflex, which helps the baby find the breast or bottle to start feeding and also promotes bonding between the mother and the baby.

Choice A is wrong because acrocyanosis is a normal condition in newborns that causes bluish discoloration of the hands and feet due to poor circulation.It is not related to muscle tone or reflexes.

Choice B is wrong because myelinization of nerves is a process that occurs gradually during development and is not influenced by tactile stimulation.Myelin is a fatty substance that covers nerve fibers and helps them transmit signals faster and more efficiently.

Choice D is wrong because reflexes are involuntary movements or actions that do not depend on conscious thought or learning.They are not directly related to growth patterns, although they may indicate the health and development of the brain and nervous system.

A transverse lie means that the baby is lying sideways across the uterus, instead of head-down or breech.

This position makes vaginal delivery impossible and increases the risk of umbilical cord prolapse, which can compromise fetal oxygen supply.Therefore, a cesarean delivery is indicated for a fetus in a transverse lie.

Choice A is wrong because having extremely slender hips does not necessarily mean that a woman cannot deliver vaginally.

The size and shape of the pelvis, not the external appearance, determines the adequacy of the birth canal.A trial of labor may be attempted for women with borderline pelvic measurements.

Choice C is wrong because fetal hyperactivity is not a reason for a cesarean delivery.

Fetal movements may vary depending on the time of day, maternal activity, maternal blood sugar level, and other factors.Fetal well-being can be assessed by fetal heart rate monitoring and biophysical profile.

Choice D is wrong because having a posterior cervix does not indicate the need for a cesarean delivery.

A posterior cervix means that the cervix is tilted toward the back of the uterus, which may make cervical dilation slower and more painful.However, with adequate contractions and maternal pushing, the cervix can move to an anterior position and allow vaginal delivery.
