Correct Answer: A

Rationale: A splenic rub is a friction rub heard on auscultation in the left upper quadrant of the abdomen, typically in patients with an enlarged spleen. The rough grating noise heard during examination is due to the rubbing together of the inflamed or irritated peritoneal surfaces surrounding the spleen. This is a classic finding in patients with splenomegaly and is often associated with left upper quadrant pain. Bowel noises (borborygmi) are typically heard in the abdomen and are softer, gurgling, or rumbling in nature. Vascular noises are related to blood flow and are typically not associated with such sounds in the abdomen.

Correct Answer: B

Rationale: The information provided about Mr. M's shortness of breath being present for the past 10 days, worsening with activity, and relieved by rest are all objective findings. These are measurable and observable facts that can be documented by healthcare professionals through physical examination, assessment, and potentially diagnostic tests. Subjective information would involve Mr. M's personal feelings or descriptions of his symptoms, which are not included in the given information.

Correct Answer: B

Rationale: Peripheral arterial disease (PAD) is considered a coronary heart disease risk equivalent, meaning it confers a similar risk as having a history of coronary heart disease itself. Individuals with PAD have a significantly increased risk of cardiovascular events such as heart attack and stroke. Therefore, when assessing the 10-year coronary heart disease risk of the 40-year-old banker, having peripheral arterial disease would be a crucial factor to consider in addition to other risk factors like hypertension, exercise habits, and smoking history.

Correct Answer: A

Rationale: The presentation of decreased bowel sounds, rebound tenderness, and involuntary guarding in the right lower quadrant is highly suggestive of acute appendicitis. These signs indicate inflammation and potential perforation of the appendix, leading to the classic symptoms of appendicitis. The pain in this case is likely due to the inflammatory process involving the appendix. The absence of abnormal findings in the rectal, inguinal, prostate, penile, and testicular examinations further supports the diagnosis of acute appendicitis as the most likely cause of the patient's pain.

Correct Answer: B

Rationale: The most likely pathologic process based on the patient's symptoms and history would be an inflammatory process. The patient's joint pain, fever, and family history of rheumatoid arthritis suggest the possibility of an autoimmune inflammatory condition like rheumatoid arthritis. Rheumatoid arthritis is a chronic inflammatory disorder that primarily affects the joints, causing pain, swelling, and stiffness. The bilateral involvement of the wrists and fingers along with a family history of rheumatoid arthritis make this diagnosis more likely than an infectious, hematologic, or traumatic process in this case.
