Correct Answer: A

Rationale: The correct answer is A: Rhesus D incompatibility. Icterus gravis and hydrops fetalis are conditions associated with hemolytic disease of the newborn, caused by Rhesus D incompatibility between the mother and fetus. This occurs when the mother is Rh-negative and the baby is Rh-positive, leading to the production of antibodies by the mother that attack the baby's red blood cells. This can result in severe jaundice (icterus gravis) and excessive fluid accumulation in the fetus (hydrops fetalis). Summary: - Choice B (ABO incompatibility) is incorrect because it typically causes less severe jaundice and anemia compared to Rhesus D incompatibility. - Choice C (Physiological jaundice) is incorrect as it is a common benign condition in newborns due to immature liver function. - Choice D (Instant perinatal death) is incorrect as it does not specifically relate to the conditions mentioned.

Correct Answer: D

Rationale: The correct answer is D because skin-to-skin contact after birth offers multiple benefits. Firstly, it helps stabilize the baby's temperature by utilizing the parent's body heat. Secondly, it promotes bonding between the parent and baby through physical closeness and touch. Finally, it can regulate the baby's heartbeat by providing a calming and reassuring environment. Therefore, all of the above choices are correct in highlighting the significance of skin-to-skin contact after birth.

Correct Answer: B

Rationale: The correct answer is B: Turtle sign. This occurs when the fetal head retracts against the perineum during delivery, resembling a turtle retracting into its shell. This indicates fetal shoulder dystocia, a serious complication. Gaskin sign (A) refers to the position of the mother during labor. Klumpke sign (C) is related to brachial plexus injuries during delivery. Chignon sign (D) is not a recognized term in obstetrics.

Correct Answer: B

Rationale: The correct answer is B: Klumpke's palsy. Neonatal injury to nerve roots C8 & T1 leads to Klumpke's palsy, characterized by paralysis of the lower arm and hand muscles. This occurs due to damage to the lower trunk of the brachial plexus. Erb's palsy (choice A) involves C5 & C6 nerve roots, causing weakness in the shoulder and upper arm. Phrenic injury (choice C) affects the diaphragm, leading to breathing difficulties. Radial palsy (choice D) results from damage to the radial nerve, causing wrist drop and weakness in forearm muscles. Klumpke's palsy specifically matches the description of injury to nerve roots C8 & T1.

Correct Answer: D

Rationale: The correct answer is D because a client is declared fit for a vaginal birth after cesarean section if their previous delivery was via spontaneous vertex delivery. This indicates that the client has successfully given birth vaginally before, reducing the risk associated with a vaginal birth after cesarean section. A, B, and C are incorrect: A: Cephalopelvic disproportion was the reason for the previous C/S, indicating potential difficulty in vaginal delivery. B: Confirmation of a multiple pregnancy does not impact the client's eligibility for a vaginal birth after cesarean section. C: Previous cesarean section does not necessarily mean the client is fit for a vaginal birth after cesarean section.
