Correct Answer: D

Rationale: In the given scenario where there are no other abnormal findings, it suggests that Mr. Thornton is experiencing anterior wall ischemia. Ischemia occurs due to inadequate blood supply to the heart muscles, often caused by a partial blockage in the coronary arteries. The absence of abnormal findings, such as ST-segment elevation or specific changes on the electrocardiogram (ECG), indicates that the issue is more likely ischemia rather than infarction. Infarction, whether NSTEMI or STEMI, would typically be associated with specific ECG changes and significant abnormalities beyond just the absence of findings. In the absence of these features, the more likely diagnosis is anterior wall ischemia.

Correct Answer: A

Rationale: A leukocyte count of 18,000/µL suggests an elevated white blood cell count, which is indicative of an inflammatory or infectious process. In the context of biliary colic, an elevated white blood cell count could be a sign of complications such as cholecystitis (inflammation of the gallbladder) or choledocholithiasis (bile duct obstruction). These complications may require urgent surgical evaluation and intervention. The other options, although concerning, do not specifically suggest a complication that necessitates immediate surgical evaluation.

Correct Answer: C

Rationale: In this case, the best approach to the patient includes assessment of nonprostate causes of nocturia. Despite the lack of significant prostate hypertrophy on digital rectal examination, the patient is experiencing bothersome lower urinary tract symptoms such as nocturia, urinary urgency, and post-void dribbling. These symptoms suggest the need to consider alternative causes beyond prostate enlargement. Factors such as overactive bladder, urinary tract infections, diabetes, sleep apnea, medications, or other systemic conditions could be contributing to the patient's symptoms. Therefore, a comprehensive evaluation to identify potential nonprostate causes of the patient's nocturia is warranted before considering more invasive prostate-specific tests like PSA, ultrasound, or symptom scales.

Correct Answer: B

Rationale: Ruptured membranes are a prerequisite for forceps delivery to avoid injury to the membranes.
