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: A

Rationale: The correct answer is A because Bishop's score assesses the readiness of the cervix for labor by evaluating descent (station of the fetal head), presentation (fetal position), and cervical dilatation, which are key indicators of cervical ripening and effacement. Descent shows the progress of the fetus through the birth canal, presentation indicates the fetal position for delivery, and cervical dilatation reflects the opening of the cervix for labor. Choices B, C, and D are incorrect as they do not encompass all the essential components of Bishop's score, which focuses on descent, presentation, and cervical dilatation.

Correct Answer: D

Rationale: The correct answer is D because fetal indications for cesarean section typically involve situations where the baby cannot safely be delivered vaginally. Cephalo-pelvic disproportion means the baby's head is too large to pass through the mother's pelvis, necessitating a C-section. Impacted face presentation can result in difficulty during delivery, also requiring a C-section. Locked twins refer to a situation where the babies are unable to move past each other during delivery, further indicating the need for a C-section. Choices A, B, and C include some relevant indications for a C-section, but they do not encompass the full range of fetal indications like choice D does.

Correct Answer: C

Rationale: The correct answer is C: Gastric retention. Mrs. Coates' symptoms of persistent and progressive discomfort are not likely due to gastric retention because she underwent a duodenal resection for a bleeding ulcer, which would bypass the stomach. Therefore, gastric retention is not a possible cause. A: Colic due to return of peristalsis is a possible cause as peristalsis returning after surgery can cause discomfort. B: Leakage from the duodenal stump is a possible cause as it can lead to abdominal discomfort postoperatively. D: Hemorrhage is a possible cause given her history of bleeding ulcer and surgery.

Correct Answer: C

Rationale: The correct answer is C: A long history of alcohol use. In this case, T. S. is brain dead and has a donor notation. However, a long history of alcohol use can lead to liver damage, making her liver unsuitable for donation. Encephalopathy (A) is a brain disorder but does not necessarily impact liver suitability. Hepatitis C infection (B) can affect the liver, but it doesn't automatically disqualify someone from being a donor. Biliary cirrhosis (D) refers to a specific liver condition, but it does not preclude someone from being a liver donor unless it has severely damaged the liver beyond use.
