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 ["0.5"]
Explanation
Step 1: (1 mg ÷ 1 mg/0.5 mL) = 0.5 mL. Final answer: 0.5 mL.
Correct Answer is A
Explanation
Choice A rationale
Continuous fetal monitoring is expected because it provides ongoing information about the fetal heart rate and contractions, which is crucial after an eclamptic seizure.
Choice B rationale
Antenatal steroid administration is not the immediate intervention post-seizure but is given to enhance fetal lung maturity if preterm delivery is anticipated.
Choice C rationale
Expectant management protocol is incorrect because active management is required in the case of an eclamptic seizure to stabilize the mother and fetus.
Choice D rationale
Umbilical artery blood flow analysis might be part of a comprehensive evaluation but is not the immediate priority post-eclampsia seizure.
