A nurse is admitting a client in labor who is HIV positive.
Which intervention is contraindicated for this client?
Application of external fetal monitors.
Prepare to administer antiviral medication.
Preparation for caesarean section delivery.
Application of internal fetal scalp electrode.
The Correct Answer is D
Choice A rationale
External fetal monitors are non-invasive and do not pose a risk of transmitting HIV from mother to baby. They are considered safe for monitoring fetal well-being in an HIV-positive mother.
Choice B rationale
Administering antiviral medication is essential in reducing the risk of mother-to-child transmission of HIV. It's a standard care practice for managing HIV-positive pregnant women.
Choice C rationale
Preparing for a caesarean section may be recommended to reduce the risk of vertical transmission of HIV during delivery, especially if the viral load is high.
Choice D rationale
Internal fetal scalp electrodes are contraindicated because they can create a portal for HIV transmission from mother to baby through small abrasions or punctures on the fetal scalp.

Correct Answer is C
Explanation
Choice A rationale
The placenta does not provide thermoregulation; that function is managed by maternal thermoregulation and the amniotic fluid which insulates the fetus.
Choice B rationale
Amniotic fluid cushions the fetus from maternal movements, not the placenta. The placenta's role is more focused on nutrient and waste exchange.
Choice C rationale
The placenta facilitates metabolic functions and gas exchange, supplying oxygen and nutrients to the fetus while removing carbon dioxide and waste products, ensuring fetal development.
Choice D rationale
The placenta doesn't provide a sterile environment. This is accomplished by the amniotic sac and amniotic fluid. The placenta connects the fetus to maternal blood supply, ensuring necessary exchanges for fetal growth.
Correct Answer is B
Explanation
Choice A rationale
Turning the newborn's head quickly to one side elicits the tonic neck reflex, not the Moro reflex. The tonic neck reflex involves the newborn's arm extending on the side where the
head is turned and the opposite arm bending at the elbow, resembling a fencing position.
Choice B rationale
Performing a sharp hand clap near the infant elicits the Moro (startle) reflex, which is characterized by the infant throwing their arms outward, opening their hands, and then bringing
the arms back in. This is a response to sudden stimuli and is a normal reflex in newborns.
Choice C rationale
Stroking the outer edge of the sole of the foot from near the heel up toward the toes elicits the Babinski reflex, not the Moro reflex. The Babinski reflex is characterized by the big toe
moving upward or toward the top surface of the foot and the other toes fanning out.
Choice D rationale
Placing a finger at the base of the newborn's toes elicits the plantar grasp reflex, not the Moro reflex. The plantar grasp reflex involves the toes curling around the finger or object
placed at the base of the toes. .
