A nurse is updating the plan of care for a newborn who is undergoing phototherapy. Which of the following actions should the nurse include in the plan?

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:

Uterine atony is the failure of the uterus to contract and retract after delivery, which can lead to excessive bleeding and hemorrhage. It is the most common cause of postpartum hemorrhage, accounting for up to 80 percent of cases. Risk factors for uterine atony include large or multiple babies, prolonged or rapid labor, overdistended uterus, use of oxytocin or magnesium sulfate during labor, and previous history of uterine atony.

Choice B reason:

Puerperal infection is an infection of the reproductive tract that occurs within six weeks after delivery. It can affect the uterus (endometritis), the bladder (cystitis), the kidneys (pyelonephritis), the breast (mastitis), or the wound (cesarean section or episiotomy).

Symptoms include fever, chills, malaise, foul-smelling lochia, pelvic pain, and wound redness or drainage. Risk factors for puerperal infection include cesarean delivery, prolonged rupture of membranes, prolonged labor, multiple vaginal examinations, retained placental fragments, and poor hygiene.

Choice C reason:

Retained placental fragments are pieces of the placenta that remain in the uterus after delivery. They can cause postpartum hemorrhage, infection, or delayed involution of the uterus. Symptoms include heavy or prolonged bleeding, fever, abdominal pain, and an enlarged uterus. Risk factors for retained placental fragments include placenta previa, placenta accrete, manual removal of the placenta, and incomplete examination of the placenta after delivery.

Choice D reason:

Thrombophlebitis is the inflammation and clotting of a vein, usually in the legs or pelvis. It can cause pain, swelling, redness, and warmth in the affected area. It can also lead to pulmonary embolism if the clot breaks off and travels to the lungs. Risk factors for thrombophlebitis include pregnancy and the postpartum period, cesarean delivery, obesity, smoking, dehydration, immobility, varicose veins, and inherited or acquired clotting disorders.
