A nurse is reinforcing teaching with the mother of a newborn who is small for gestational age. Which of the following should the nurse include as a cause of this condition?

Choice A reason:

The newborn has hypotonia. This is not a specific sign of brachial plexus injury, as hypotonia can have many other causes, such as genetic disorders, infections, or brain damage.

Hypotonia is a general term for low muscle tone or weakness, which can affect the whole body or specific parts.

Choice B reason:

The newborn does not demonstrate the Moro reflex. This is a sign of brachial plexus injury, especially if it affects only one arm. The Moro reflex is a startle response that causes the baby to throw out the arms and legs, then curl them in when startled. A brachial plexus injury can impair the nerve function in the shoulder, arm, or hand, leading to decreased movement or sensation in the upper extremity. If the baby does not show the Moro reflex on one side, it may indicate damage to the upper brachial plexus nerves (C5-C7), also known as Erb's palsy.

Choice C reason:

The newborn cries continually. This is not a specific sign of brachial plexus injury, as crying can have many other causes, such as hunger, discomfort, or colic. Crying is a normal way for babies to communicate their needs and feelings. Crying does not necessarily indicate pain from a brachial plexus injury, as infants' nerves behave differently from adults' and they may not experience much pain from this condition.

Choice D reason:

The newborn has tremors. This is not a specific sign of brachial plexus injury, as tremors can have many other causes, such as cold temperature, low blood sugar, or withdrawal from maternal medications. Tremors are involuntary movements of the muscles that can affect the whole body or specific parts. Tremors do not necessarily indicate nerve damage from a brachial plexus injury, as this condition usually causes weakness or paralysis of the affected muscles.

Choice A reason:

This statement is not appropriate because it does not provide any information or education to the client who wants to know about VBAC. It also implies that the nurse does not have any knowledge or expertise on the topic, which may undermine the client's trust and confidence in the nurse.

Choice B reason:

This statement is not appropriate because it is not evidence-based and may discourage the client from considering VBAC as a possible option. According to research, VBAC is associated with fewer complications than an elective repeat C-section for many women who had prior

cesarean deliveries. A repeat C-section also carries risks such as infection, bleeding, injury to organs, and placental problems in future pregnancies.

Choice C reason:

This statement is appropriate because it is accurate and informative. The type of uterine incision used for the prior C-section is one of the most important factors that determine the eligibility and success of VBAC. A low transverse or low vertical incision is usually compatible with VBAC, while a high vertical (classical) incision is not recommended due to the risk of uterine rupture.

Choice D reason:

This statement is not appropriate because it dismisses the client's concern and does not address their question. It also implies that the nurse does not respect the client's autonomy and right to make informed decisions about their care. The client may benefit from learning about VBAC early in their pregnancy so that they can weigh the pros and cons and discuss their preferences with their provider.
