A nurse is assessing a client who is postpartum and is experiencing hemorrhagic shock.
Which of the following findings should the nurse expect?

Choice A rationale

Erb-Duchenne palsy, a form of brachial plexus injury (C5-C6), primarily affects the nerves controlling the shoulder and upper arm muscles. It generally does not affect cranial nerves (such as IX and X, which control swallowing) or the muscles of the mouth, thus typically preserving the ability to suck and swallow.

Choice B rationale

The Moro (startle) reflex involves symmetrical extension and abduction of the arms followed by adduction and flexion. An injury to the brachial plexus on one side impairs the motor function of that arm, resulting in the characteristic absence of the reflex in the affected extremity, which is a key diagnostic finding.

Choice C rationale

The Babinski reflex is a normal neurological finding in infants up to about 2 years old, reflecting immature corticospinal tracts. It is a foot reflex and is unrelated to a brachial plexus injury in the neck and shoulder area; thus, its presence is not a specific finding for Erb-Duchenne palsy.

Choice D rationale

Cleft palate is a congenital craniofacial malformation resulting from incomplete fusion of the palatine shelves during fetal development. It is a structural anomaly of the mouth and is not a finding or complication associated with Erb-Duchenne palsy, which is a neuromuscular injury sustained, most commonly, during birth.

Choice A rationale

The umbilical cord stump typically dries, shrivels, and spontaneously separates from the infant's abdomen due to a process similar to dry gangrene (ischemic necrosis) within one to three weeks after birth; therefore, this statement indicates correct understanding of the normal timeline for cord care and healing.

Choice B rationale

A newborn's skin is sensitive and prone to drying, and daily tub baths are unnecessary and may cause skin irritation; sponge baths are used until the cord stump falls off, and then typically only two to three baths per week are recommended initially to maintain skin integrity.

Choice C rationale

The correct procedure for using a bulb syringe is to compress the bulb before insertion into the mouth (or nose) to create the negative pressure, then release the compression slowly to suction mucus; compressing it after insertion would expel air into the baby's mouth instead of suctioning.

Choice D rationale

Placing a baby on their side to sleep increases the risk of the baby rolling onto their stomach, which is associated with an elevated risk of Sudden Infant Death Syndrome (SIDS); the universally recommended safe sleep position is supine (on the back).
