You are examining an unconscious patient from another region and notice Beau's lines, a transverse groove across all of her nails, about 1 cm from the proximal nail fold. What would you do next?

Correct Answer: C

Rationale: Beau's lines are transverse grooves or depressions in the nails that occur from a temporary disruption in nail growth. These lines can be caused by a variety of factors, including systemic diseases, medication use, trauma, or environmental stressors. However, one of the most common causes of Beau's lines is a significant physiological stress such as a severe illness or major surgery that occurred about 3 months prior to the appearance of the lines. Therefore, looking for information from family and records regarding any problems that occurred around 3 months ago is the most appropriate next step to understand the underlying cause of Beau's lines in this unconscious patient. This information can provide crucial insights into the patient's medical history and potential underlying health issues that may need to be addressed.

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: D

Rationale: In this situation, it is important to prioritize active listening over taking detailed notes. By pushing away from the keyboard or putting down your pen, you are signaling to the patient that you are fully present and engaged in listening to their story. This will help foster trust and encourage the patient to continue sharing their personal history. Taking notes can be done later, but the immediate focus should be on providing a supportive and attentive environment for the patient to share their experiences.

Correct Answer: C

Rationale: Lateral epicondylitis, commonly known as tennis elbow, is a condition characterized by pain and tenderness on the lateral (outside) aspect of the elbow. It is typically caused by overuse or repetitive strain of the extensor muscles in the forearm, leading to inflammation of the tendons attached to the lateral epicondyle of the humerus.

Correct Answer: B

Rationale: A condylar joint is a type of synovial joint that allows movement in two planes, typically flexion/extension and abduction/adduction. The interphalangeal joints of the hand, which are the joints between the phalanges (finger bones), exhibit this type of movement, making them an example of a condylar joint. The hip joint (choice A) is a ball-and-socket joint, the temporomandibular joint (choice C) is a hinge joint, and the intervertebral joint (choice D) is a cartilaginous joint, none of which are examples of condylar joints.

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: 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.

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.
