A 57-year-old maintenance worker comes to your office for evaluation of pain in his legs. He has smoked two packs per day since the age of 16, but he is otherwise healthy. You are concerned that he may have peripheral vascular disease. Which of the following is part of common or concerning symptoms for the peripheral vascular system?

Correct Answer: A

Rationale: Intermittent claudication is a common symptom of peripheral vascular disease. It is characterized by muscle pain or cramping in the legs, usually in the calves, thighs, or buttocks, that occurs during physical activity such as walking and is relieved by rest. This symptom is due to inadequate blood flow to the muscles during exercise. It is important to assess for intermittent claudication in patients with risk factors such as smoking, diabetes, and hypertension, as it may indicate underlying peripheral arterial disease. The other symptoms listed (chest pressure with exertion, shortness of breath, knee pain) are not typically associated with peripheral vascular disease.

Correct Answer: A

Rationale: The most appropriate amount for a weekly weight reduction goal is typically .5 to 1 pound per week. This rate of weight loss is considered safe and sustainable in the long term. Losing weight too quickly (options B, C, D) can be harmful to your health and may lead to muscle loss, nutritional deficiencies, and a slow metabolism. Rapid weight loss is also harder to maintain in the long run. Gradual weight loss of .5 to 1 pound per week allows for healthy changes to diet and exercise habits, making it more likely to be maintained over time. It is also more likely to result in lasting weight loss and overall improvements in health and well-being.

Correct Answer: B

Rationale: A sudden, painful unilateral loss of vision is a medical emergency that may be caused by central retinal artery occlusion. This condition occurs when the main artery supplying blood to the retina becomes blocked, leading to a sudden and severe reduction in blood flow to the eye. The lack of blood flow can cause irreversible damage to the retina, resulting in a significant loss of vision. Patients with central retinal artery occlusion typically present with sudden, painless, and severe vision loss in one eye. Immediate medical attention is crucial to try to restore blood flow and minimize potential permanent vision loss in these cases. Vitreous hemorrhage, macular degeneration, and optic neuritis do not typically present with sudden, painful unilateral loss of vision as seen in central retinal artery occlusion.

Correct Answer: B

Rationale: The scenario described suggests that Ray experiences pain only when actively lifting his arm over his head, which indicates the issue is likely originating from structures outside of the joint itself. When the shoulder is moved passively (moved by an external force), there is full range of motion without pain, suggesting that the limitation and pain occur due to muscles, tendons, or ligaments surrounding the joint rather than within the joint itself. In this case, the joint disease is likely to be extra-articular, involving structures such as muscles or tendons rather than being articular in nature.

Correct Answer: B

Rationale: A varicocele is a common cause of a "bag of worms" feeling in the scrotum. It occurs due to the dilation of the veins within the spermatic cord, leading to a palpable mass above the testicle. Varicoceles are more commonly found on the left side due to the anatomy of the left testicular vein, which drains into the left renal vein at a right angle, making it more susceptible to increased pressure and dilation.

Correct Answer: A

Rationale: Intermittent claudication is a common symptom of peripheral vascular disease. It is characterized by muscle pain or cramping in the legs, usually in the calves, thighs, or buttocks, that occurs during physical activity such as walking and is relieved by rest. This symptom is due to inadequate blood flow to the muscles during exercise. It is important to assess for intermittent claudication in patients with risk factors such as smoking, diabetes, and hypertension, as it may indicate underlying peripheral arterial disease. The other symptoms listed (chest pressure with exertion, shortness of breath, knee pain) are not typically associated with peripheral vascular disease.

Correct Answer: C

Rationale: The presence of an irregular, asymmetric, hard nodule on the posterior surface of the prostate detected during digital rectal examination raises suspicion for prostate cancer. Prostate cancer commonly presents with nodules or indurations on the prostate gland during physical examination. Other findings, such as no inflammation, masses, or fissures in the anus and normal examinations of the scrotum and penis, further support the likelihood of prostate cancer as the most probable diagnosis in this case. Additional laboratory results, including prostate-specific antigen (PSA) levels, can help confirm the diagnosis. Both benign prostatic hyperplasia (BPH) and prostatitis typically present with different symptoms than those described in the scenario, making prostate cancer the most likely disorder based on the provided information. Anorectal cancer is less likely given the absence of findings indicating involvement of the anus or rectum in this case.

Correct Answer: D

Rationale: The patient's presentation of tenderness in the left upper quadrant and epigastric area, along with normal bowel sounds, is suggestive of acute pancreatitis. This condition typically presents with severe, steady epigastric pain that may radiate to the back or left upper quadrant. Patients may also have tenderness on physical examination in these areas. Acute pancreatitis is commonly associated with risk factors such as gallstones or excessive alcohol consumption.

Correct Answer: A

Rationale: The description provided fits the criteria for tension-type headache. Tension-type headaches are typically described as a mild to moderate, dull, band-like pressure or tightness around the head. They can last from minutes to days and are often triggered by stress, anxiety, poor posture, or prolonged computer use. The absence of symptoms like photophobia and nausea, along with the response to over-the-counter medication, further support the diagnosis of tension-type headache in this case. Other headache types such as migraines or cluster headaches usually present with additional symptoms like nausea, photophobia, or tearing of the eye, which are not mentioned in this scenario. Analgesic rebound headaches typically occur in individuals who overuse pain medications, leading to worsening headaches when the medication wears off, but this patient's history does not suggest such misuse.
