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.

Correct Answer is D
Explanation
Choice A rationale
The amnion is a membrane that encloses the amniotic fluid but does not provide nutrients to the embryo.
Choice B rationale
The chorion forms part of the placenta and contributes to nutrient and gas exchange once the placenta develops, but it does not provide nutrients before the placenta forms.
Choice C rationale
The allantois is involved in early fluid exchange and waste management but does not provide nutrients before the placenta forms.
Choice D rationale
The yolk sac provides nutrients to the developing embryo before the placenta is fully functional, supporting early embryonic development.
Correct Answer is B
Explanation
Choice A rationale
Magnesium sulfate is used to manage preeclampsia and prevent seizures, not for treating postpartum hemorrhage. It does not address the causes of excessive vaginal bleeding post-birth.
Choice B rationale
Tranexamic acid is an antifibrinolytic agent that helps reduce bleeding by preventing the breakdown of blood clots, making it suitable for managing postpartum hemorrhage.
Choice C rationale
Betamethasone is a corticosteroid used to mature fetal lungs in preterm labor, not for treating postpartum hemorrhage. It has no role in managing excessive bleeding after birth.
Choice D rationale
Terbutaline is a tocolytic used to delay preterm labor by relaxing uterine muscles. It is not used to manage postpartum hemorrhage and excessive vaginal bleeding.
