The gradual rewarming process in the management of hypothermia neonatorum is aimed at

Correct Answer: B

Rationale: In the management of hypothermia neonatorum, the gradual rewarming process is aimed at preventing shock. Rapid rewarming can lead to vasodilation, causing a sudden drop in blood pressure and potentially leading to shock. Gradual rewarming helps the body adjust slowly to prevent this. Providing energy (Choice A) is not the primary goal of rewarming in hypothermia. Providing comfort (Choice C) is important but not the main purpose of the rewarming process. Preventing burns (Choice D) is not directly related to the rewarming process but is important to ensure the safety of the neonate during the rewarming process.

Correct Answer: B

Rationale: Classical vitamin K deficiency bleeding occurs within the neonatal stage because newborns have low levels of vitamin K, which is essential for blood clotting. This deficiency typically manifests between 1-7 days after birth. Bleeding within the first 24 hours (choice A) is unlikely as it is too early for vitamin K deficiency to cause symptoms. Bleeding within infancy (choice C) is incorrect as it specifically refers to the neonatal stage. Bleeding within the first week of birth (choice D) is a close distractor, but the critical period for classical vitamin K deficiency bleeding is within the neonatal stage, which is slightly more specific than the first week of birth.

Correct Answer: C

Rationale: The correct answer is C: Truncus arteriosus. In this condition, there is a single large vessel arising from the heart that gives rise to the systemic, pulmonary, and coronary arteries. This results in mixing of oxygenated and deoxygenated blood, leading to severe cyanosis and inadequate oxygenation of the body, causing immediate death after birth. A: Pulmonary stenosis and B: Aortic coarctation typically do not cause immediate death after birth. D: Ductus arteriosus is a normal fetal structure that closes shortly after birth and its presence would not directly cause immediate death.

Correct Answer: A

Rationale: The correct answer is A: Increases risk of gestational diabetes. Maternal obesity can lead to insulin resistance, increasing the likelihood of developing gestational diabetes during pregnancy. This condition can have negative effects on both the mother and the baby. B: Miscarriage is not directly linked to maternal obesity but can be influenced by other factors. C: Maternal obesity is not a direct cause of anemia during pregnancy. Anemia is usually related to iron deficiency or other factors. D: Maternal obesity is actually associated with an increased risk of preterm labor, not a reduced chance. This is due to various complications such as hypertension and preeclampsia.

Correct Answer: D

Rationale: The correct answer is D because all the choices (A, B, and C) are risks associated with cesarean sections. Infection can occur at the incision site, blood loss is a common concern during surgery, and cesarean sections typically have a longer recovery time compared to vaginal delivery. Therefore, all of these risks are potential complications of undergoing a cesarean section. The other choices (A, B, and C) are incorrect individually because they only represent a subset of the risks associated with cesarean sections, while choice D encompasses all potential risks.
