The baby dies immediately after birth due to the presence of

Correct Answer: C

Rationale: The correct answer is C: Truncus arteriosus. In this congenital heart defect, a single large blood vessel arises from the heart instead of the normal two separate vessels (aorta and pulmonary artery). This results in mixing of oxygenated and deoxygenated blood, leading to severe cyanosis and inadequate oxygen supply to the body. This condition is incompatible with life, causing immediate death after birth. A: Pulmonary stenosis and B: Aortic coarctation are also congenital heart defects but do not typically result in immediate death after birth. Pulmonary stenosis obstructs blood flow to the lungs, while aortic coarctation causes narrowing of the aorta. D: Ductus arteriosus is a normal fetal blood vessel that connects the pulmonary artery and the aorta but usually closes shortly after birth. Failure of closure can lead to health issues, but it is not typically a cause of immediate death after birth.

Correct Answer: D

Rationale: The correct answer is D because hypoplastic left heart syndrome involves underdevelopment of the left ventricle, aortic valve, and aortic arch. The left ventricle is typically small and unable to adequately pump blood to the body. The aortic valve is often malformed, leading to difficulties in blood flow from the heart to the body. Additionally, the aortic arch may be narrow or underdeveloped, further impacting blood circulation. Choice A is incorrect as it includes the pulmonary veins, which are not typically affected in hypoplastic left heart syndrome. Choice B is incorrect as it focuses on the left atrium and pulmonary vessels, which are not the primary structures affected in this condition. Choice C is incorrect as it mentions the aorta arch, venacava, and right atrium, which are not primarily associated with hypoplastic left heart syndrome.

Correct Answer: C

Rationale: The correct answer is C because living wills are typically not honored for terminally ill patients with impaired cognition. Firstly, living wills require the patient to be of sound mind to make decisions. Secondly, in the case of a cognitively impaired patient, their ability to express their wishes and understand the implications may be compromised. Therefore, healthcare providers may not be able to honor the living will accurately. Choices A, B, and D are incorrect because A) competency can be determined by healthcare professionals, B) impaired cognition can lead to incompetence, and D) informed consent requires the patient to understand the decision-making process.

Correct Answer: B

Rationale: The correct answer is B: Hyperemesis gravidarum. This condition is characterized by severe nausea and vomiting during pregnancy, leading to inability to eat or retain feeds. It is associated with significant weight loss and dehydration. Other choices are incorrect because: A: Weight gain control is not the primary concern when hyperemesis gravidarum is present. C: Morning sickness typically does not cause severe inability to eat or retain feeds. D: Preeclampsia is a separate condition characterized by high blood pressure and organ damage, not directly related to feeding difficulties.

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. TB in pregnancy can lead to premature labor due to the fever experienced. Fever increases the risk of premature labor by triggering uterine contractions. Poor maternal appetite (A) and severe anemia (B) may impact the mother's health but are not directly linked to premature labor. Adverse reactions of anti-TB drugs (C) could potentially affect the mother's health but are not a direct cause of premature labor.

Correct Answer: D

Rationale: The correct answer is D because deep transverse arrest refers to a situation where the fetal head fails to rotate and descend in the pelvis due to the occiput and sinciput being at the same level. This leads to a prolonged labor. Choice A is incorrect because flexion can be inadequate in deep transverse arrest. Choice B is incorrect because it is not solely caused by uterine contractions but rather fetal malposition. Choice C is incorrect because a well-curved sacrum is not a defining factor in deep transverse arrest.

Correct Answer: B

Rationale: Step-by-step rationale for why choice B is correct: 1. The ACCF/AHA recommends cardiac consultation before an operation for patients on antiplatelet therapy to assess the risk of bleeding versus thrombotic events. 2. Cardiac consultation helps determine the necessity of continuing, modifying, or stopping antiplatelet therapy. 3. This individualized approach ensures optimal perioperative management based on the patient's cardiovascular risk profile. 4. Choice A is incorrect as stopping antiplatelet therapy for 10 days can increase the risk of thrombotic events. 5. Choice C is incorrect as it oversimplifies the decision-making process without considering the patient's specific risks. 6. Choice D is incorrect because initiating antiplatelet therapy in all high-risk cardiac procedures may not be necessary for every patient.

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.
