Correct Answer: B

Rationale: Postdatism refers to a pregnancy that extends beyond the normal gestation period of 280 days. The correct answer is B (294 days) as it is more than the standard 280-day term. Choice A (280 days) is the normal term, not postdatism. Choices C (290 days) and D (287 days) are also below the 294-day mark, making them incorrect for defining postdatism.

Correct Answer: A

Rationale: The correct answer is A: TRUE. This is because BCG vaccination for newborns is recommended even if the mother is smear-negative for tuberculosis, as it helps protect the newborn from severe forms of TB. Smear status of the mother does not impact the need for BCG vaccination in the neonate. Choice B is incorrect as it falsely implies that BCG should not be given in this scenario. Choices C and D are not applicable as they do not provide any information.

Correct Answer: D

Rationale: The correct answer is D because in deep transverse arrest, the sagittal suture of the fetal head is typically aligned with the oblique diameter of the pelvis, causing an obstruction in the descent of the baby. This alignment leads to a difficult labor scenario where the baby's head cannot pass through the pelvis due to the mismatch in diameters. Choices A, B, and C are incorrect because they do not accurately describe the specific anatomical alignment that characterizes deep transverse arrest. Choice A refers to occipito-frontal diameter, choice B refers to sub-occipito-bregmatic diameter, and choice C mentions a face to pubis delivery, which are not the defining features of deep transverse arrest.

Correct Answer: C

Rationale: The correct answer is C: Autonomy and beneficence. Autonomy refers to the patient's right to make their own decisions regarding their healthcare. In this case, the patient is refusing reintubation, exercising his autonomy. However, beneficence, the duty to act in the patient's best interest, also comes into play as the patient's refusal could lead to respiratory failure and death. The conflict arises from balancing the patient's autonomy with the healthcare provider's duty to provide beneficial care. Choices A, B, and D are incorrect because they do not accurately capture the ethical conflict present in the scenario. Veracity (A) refers to truthfulness, which is not the primary issue here. Nonmalfeasance (B) is the duty to do no harm, which is not directly relevant to the conflict between the patient's autonomy and the need for beneficial care. Justice (D) relates to fairness in resource allocation and is not the primary issue in this case.

Correct Answer: B

Choice A (280 days) is the normal term, not postdatism. Choices C (290 days) and D (287 days) are also below the 294-day mark, making them incorrect for defining postdatism.
