You are evaluating a 40-year-old banker for coronary heart disease risk factors. He has a history of hypertension, which is well-controlled on his current medications. He does not smoke; he does 45 minutes of aerobic exercise five times weekly. You are calculating his 10- year coronary heart disease risk. Which of the following conditions is considered to be a coronary heart disease risk equivalent?

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: 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: A

Rationale: When a patient presents with epistaxis (nosebleed), other causes such as intracranial hemorrhage should be considered. Intracranial hemorrhage refers to bleeding within the skull, which can sometimes manifest as epistaxis. Common symptoms of intracranial hemorrhage include severe headache, altered mental status, focal neurological deficits, and sometimes, epistaxis. It is essential to assess for signs of increased intracranial pressure or neurological deficits if a patient with epistaxis has a history of trauma or other risk factors for intracranial bleeding. Immediate medical evaluation and imaging studies may be necessary to rule out intracranial hemorrhage in such cases to prevent serious consequences.

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: A

Rationale: When examining a newborn and noting that the right testicle is not in the scrotum, it is important to refer the newborn to a pediatric urologist for further evaluation and management. This condition could be a case of undescended testis (cryptorchidism), where the testicle fails to descend into the scrotum. Early intervention is crucial as the undescended testis may lead to complications such as infertility, testicular cancer, and inguinal hernia. Urology specialists can determine the best course of action to bring down the testis and ensure proper testicular development. Waiting or attempting manual descent without expertise could lead to complications, so it is best to involve a urologist for proper assessment and management.

Correct Answer: C

Rationale: The characteristics described - being louder and higher in pitch, with a short silence between inspiration and expiration, and expiration being longer than inspiration - are indicative of the bronchial lung sound. The bronchial sound is typically heard over the trachea area and can be louder and higher-pitched than other lung sounds due to conduction of sounds through the bronchial tree. The short silence between inspiration and expiration is due to the short expiratory phase during which air rushes out quickly, whereas expiration is longer than inspiration in this sound due to the increased airflow velocity during expiration.

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.
