Correct Answer: B

Rationale: The correct answer is B: Fetal head retracts against the perineum. This sign indicates possible shoulder dystocia as it suggests the baby's shoulders are impacted and unable to pass through the birth canal. The retraction of the fetal head against the perineum is a classic sign of shoulder dystocia, which requires specific maneuvers to dislodge the shoulders and facilitate delivery. A: Failure of internal rotation of the head is not specific to shoulder dystocia. C: Gentle traction should not be applied in cases of shoulder dystocia as it can worsen the situation. D: The occiput restituting towards the left side is not a sign of shoulder dystocia, as it refers to the rotation of the fetal head during delivery.

Correct Answer: B

Rationale: The correct answer is B: Hypoglycaemia. Neonates born to diabetic mothers are at risk of hypoglycaemia due to high insulin levels in utero. Feeding the newborn within the first 15 minutes helps maintain blood glucose levels. Hypocalcaemia, hyponatraemia, and hypokalaemia are not typically immediate concerns in neonates born to diabetic mothers.

Correct Answer: C

Rationale: The correct answer is C because culture and level of education can significantly impact how women perceive and react to labor pain. Culture shapes beliefs, norms, and attitudes towards pain, influencing coping mechanisms. Education can enhance understanding of pain management techniques. Option A lacks specificity on how preparedness and fatigue affect perception. Option B oversimplifies by only considering culture and age. Option D overlooks the influence of education and focuses solely on anxiety and number of deliveries.

Correct Answer: A

Rationale: The correct answer is A: Radiographs. Radiographs, specifically skull X-rays, are most useful in assessing for findings consistent with a history of abuse in this case. Radiographs can detect fractures, such as skull fractures or facial bone fractures, which are common in cases of physical abuse. These fractures may not always be clinically evident but can be identified on X-rays. Explanation of other choices: B: CT scan without contrast - While a CT scan can provide detailed imaging of the head, it may not be necessary in this case as the patient's neurologic examination is within normal limits. Also, radiographs are more cost-effective and can detect fractures effectively. C: MRI - MRI is not typically used as the first-line imaging modality for suspected head trauma due to its cost and time-consuming nature. Radiographs are more appropriate for initial evaluation. D: PET scan - PET scans are used to detect metabolic activity in tissues and are not typically indicated for assessing acute traumatic injuries like fractures associated with

Correct Answer: D

Rationale: The correct answer is D: Breast cancer. The patient's breast cancer is the reason she is ineligible to donate organs. Breast cancer is a contraindication for organ donation due to the risk of cancer transmission to the recipient. Traumatic brain injury (choice B) and renal failure (choice A) are not absolute contraindications to organ donation. Gram-negative infection (choice C) may temporarily disqualify the patient but can be treated, unlike breast cancer. In summary, breast cancer poses the highest risk of organ recipient harm compared to the other medical conditions listed.
