A nurse is reinforcing teaching about fetal anatomy ultrasound to a client who is at 20 weeks of gestation.
Which of the following information should the nurse include?
The client will be positioned in a prone position.
The ultrasound will occur at 13 weeks of gestation.
The ultrasound will be transvaginal.
The client must have a full bladder.
The Correct Answer is D
Choice A rationale
The client will be positioned in a prone position is incorrect because the prone position is not used for fetal anatomy ultrasounds.
Choice B rationale
The ultrasound will occur at 13 weeks of gestation is incorrect as the typical timing for a detailed fetal anatomy scan is around 18-22 weeks of gestation, not 13 weeks.
Choice C rationale
The ultrasound will be transvaginal is incorrect because at 20 weeks of gestation, a transabdominal ultrasound is more commonly used rather than a transvaginal one.
Choice D rationale
The client must have a full bladder is correct because a full bladder helps lift the uterus out of the pelvis, providing a clearer view during the ultrasound.

Correct Answer is D
Explanation
Choice A rationale
Rh positive clients with Rh positive newborns do not require Rho(D) immune globulin because there is no risk of Rh incompatibility.
Choice B rationale
If both the client and the newborn are Rh positive, Rho(D) immune globulin is not needed since there is no risk of the client developing antibodies against Rh positive cells.
Choice C rationale
Rh negative clients with Rh negative newborns also do not require Rho(D) immune globulin since there is no Rh positive blood to cause an immune response.
Choice D rationale
Rh negative clients with Rh positive newborns need Rho(D) immune globulin to prevent the client from developing antibodies against Rh positive blood, which could affect future pregnancies.
Correct Answer is A
Explanation
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.
