Correct Answer: A

Rationale: The yellow skin observed in the newborn suggests jaundice. Maternal/newborn blood group incompatibility is a common cause of jaundice in newborns. This occurs when the mother and baby have different blood types, leading to the baby's immune system attacking the red blood cells, causing jaundice. Physiologic jaundice, which is a normal process due to the breakdown of red blood cells in newborns, typically presents after the first 24 hours of life. Absence of vitamin K leads to bleeding issues, not jaundice. Maternal cocaine abuse does not directly cause jaundice in newborns.

Correct Answer: B

Rationale: A surge of energy is a common sign that precedes labor. This burst of energy, often referred to as the 'nesting instinct,' is believed to occur as the body prepares for labor, prompting the individual to undertake tasks to prepare for the arrival of the baby. Decreased vaginal discharge is not a typical sign preceding labor. Urinary retention is not a sign that precedes labor and may indicate another issue. Weight gain of 0.5 to 1.5 kg is not a specific sign of impending labor.

Correct Answer: C

Rationale: The correct answer is C: "Breech." The RSA position indicates that the fetus is in a breech presentation. In a breech presentation, the buttocks or feet are positioned to be delivered first, which can impact the mode of delivery and require close monitoring during labor and birth. Choice A (Vertex) refers to the head-first presentation, which is considered the normal and most common presentation for birth. Choice B (Shoulder) does not represent a specific fetal presentation. Choice D (Mentum) refers to the chin presentation, which is also not relevant in this scenario.

Correct Answer: A

Rationale: The correct answer is A: Perform a sharp hand clap near the infant. The Moro reflex, also known as the startle reflex, is elicited by a sudden stimuli such as a sharp hand clap near the infant. This reflex is characterized by the infant's arms extending and then flexing with a distinctive 'startle' motion. It is a normal and expected reflex in newborns, typically disappearing by 3-6 months of age. Choices B, C, and D are incorrect because they do not elicit the Moro reflex; holding the newborn vertically (choice B) or placing a finger at the base of the newborn's toes (choice C) are associated with other reflexes, while turning the newborn's head quickly to one side (choice D) is related to the tonic neck reflex.

Correct Answer: B

Rationale: Kegel exercises are beneficial during pregnancy to help strengthen pelvic muscles, which is crucial for childbirth. Pelvic muscle stretching during birth is a key aspect of labor, making choice B the correct statement indicating understanding of the teaching. Choices A, C, and D are incorrect because Kegel exercises primarily focus on strengthening pelvic floor muscles to support the uterus, bladder, and bowel, aiding in labor and delivery. They are not directly related to preventing constipation, decreasing backaches, or preventing stretch marks.
