Correct Answer: C

Rationale: The correct answer is C: Decompression of the colon with rectal tube. This is the most appropriate intervention for a patient with acute colonic pseudo-obstruction (ACPO), also known as Ogilvie's syndrome. In this condition, there is colonic distention without an actual mechanical obstruction, leading to symptoms like abdominal pain, distention, and high-pitched bowel sounds. Decompression with a rectal tube can help relieve the distention and prevent complications like perforation. Choice A (stimulant laxative) is incorrect because ACPO is not due to simple constipation, so laxatives would not be effective. Choice B (carcinoma of the bowel) is unlikely given the acute onset and lack of risk factors. Choice D (angiography for mesenteric ischemia) is not indicated in this case as there are no signs of acute ischemia. In summary, the correct choice is C because it directly addresses the underlying issue of colonic distention in

Correct Answer: A

Rationale: Step-by-step rationale: 1. Cognitive ability is important for decision-making during surgery. 2. Functional status helps assess the patient's ability to recover post-surgery. 3. Competency assessment ensures the patient can consent to surgery. 4. Frailty score predicts surgical outcomes in geriatric patients. 5. Cognitive ability is not typically assessed preoperatively in the ACS/NSQIP guidelines. Summary: - A: Cognitive ability is not typically part of preoperative evaluation. - B: Functional status is important for post-surgery recovery. - C: Competency assessment is crucial for informed consent. - D: Frailty score helps predict surgical outcomes in geriatric patients.

Correct Answer: D

Rationale: Non-infective mastitis is associated with adenitis because it refers to inflammation of breast tissue without an infection. Adenitis specifically involves inflammation of the lymph nodes, which can be a common cause of non-infective mastitis. Cellulitis (A) is an infection of the skin and tissues beneath the skin, not specific to mastitis. Flat (B) and bifid (C) nipples are anatomical variations that do not directly relate to the inflammation of breast tissue.

Correct Answer: A

Rationale: The correct answer is A: Symptom are absent and abnormal specific laboratory results. Chemical diabetes mellitus refers to a condition where there are abnormal specific laboratory results indicating diabetes without the presence of any symptoms. This classification is based on objective data from laboratory tests rather than subjective symptoms. Choices B, C, and D are incorrect as they do not align with the definition of chemical diabetes mellitus, which focuses on laboratory results rather than symptoms, congenital abnormalities, or pregnancy outcomes.

Correct Answer: A

Rationale: The correct answer is A because an estimated fetal weight below 3500 grams indicates a lower risk of complications during childbirth. Higher fetal weight increases the likelihood of shoulder dystocia and birth injuries. Maternal body mass index, gestational age, and maternal age do not directly impact the likelihood of a favorable outcome during a trial of scar.
