A nurse is collecting data on a newborn who has experienced Duchenne-Erb (Erb's) palsy.
Which of the following manifestations should the nurse expect?
Absent Moro reflex, arm extended at the elbow and positioned against body with decreased grasp on affected side.
Asymmetry of the face during crying and drooping of the corner of the mouth on affected side.
Asymmetry of Moro reflex, arm externally rotated, and grasp reflex absent on affected side.
Asymmetry of Moro reflex, crepitus, no movement, swelling, and tenderness on palpation of affected arm.
The Correct Answer is A
Choice A rationale
Duchenne-Erb (Erb's) palsy is a type of brachial plexus injury that commonly results in an absent Moro reflex on the affected side, an extended arm at the elbow, and decreased grasp. These symptoms arise from injury to the fifth and sixth cervical nerves, leading to motor deficits.
Choice B rationale
This describes facial nerve palsy, not Erb's palsy. Facial nerve palsy affects the muscles of the face, leading to asymmetry during crying and drooping of the mouth's corner on the affected side.
Choice C rationale
While asymmetry of the Moro reflex is accurate, this choice incorrectly states that the arm is externally rotated and the grasp reflex is absent, which aligns more with a total brachial plexus injury rather than Erb's palsy.
Choice D rationale
Crepitus, no movement, swelling, and tenderness on palpation are indicative of a fracture rather than Erb's palsy. These symptoms suggest bone injury rather than nerve damage.

Choice B rationale
Von Willebrand disease is a bleeding disorder that can lead to excessive bleeding, increasing the risk of postpartum hemorrhage due to impaired blood clotting.

Correct Answer is A
Explanation
Choice A rationale
Car seats should not be purchased used as their history is unknown. There might be unseen damages or recalls that could compromise the safety of the infant.
Choice B rationale
The chest clip should be at the infant's armpit level, not shoulder level. Incorrect positioning can affect the restraint system's efficiency.
Choice C rationale
Infants should not wear coats in their car seats because bulky clothing can prevent the harness from fitting snugly, reducing its effectiveness in a crash.
Choice D rationale
Infant car seats should remain rear-facing until at least the age of 2 or until they reach the maximum weight/height limit of the seat, not turn forward-facing at the first birthday.
