A patient comes to the emergency room for evaluation of shortness of breath. To which anatomic region would you assign the symptom?

Correct Answer: C

Rationale: Shortness of breath is commonly associated with issues related to the heart and cardiovascular system. Conditions such as heart failure, coronary artery disease, or arrhythmias can lead to symptoms like shortness of breath. Therefore, the symptom of shortness of breath would be assigned to the cardiac anatomic region.

Correct Answer: C

Rationale: For a new patient with the chief complaint of "I am here to establish care," a comprehensive health history would be appropriate. In this scenario, since the patient is new to the healthcare provider, it is important to gather detailed information about the patient's past medical history, family history, social history, medications, allergies, and specific health concerns. This comprehensive health history will help the healthcare provider establish a baseline of the patient's overall health and identify any potential risk factors or underlying conditions that may impact future care and treatment decisions. Additionally, obtaining a thorough health history is essential in building a strong patient-provider relationship and providing patient-centered care.

Correct Answer: B

Rationale: Asking Mr. Q. when his last drink was is an open-ended question that can provide valuable information regarding his alcohol consumption patterns. This question allows Mr. Q. to disclose whether he has been drinking recently and can help determine the frequency and quantity of his alcohol consumption. It avoids leading or judgmental language, which can help build rapport and facilitate a more honest conversation about his alcohol use. By knowing when his last drink was, you can better assess the potential impact of alcohol on his current symptoms of fatigue and further explore any potential issues related to alcohol abuse.

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: 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: 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: B

Rationale: The patient's history of swimming and presenting symptoms of ear pain, drainage, and manipulation tenderness are suggestive of external otitis, commonly known as swimmer's ear. External otitis is an infection of the outer ear canal, which can be caused by prolonged moisture exposure, trauma, or bacterial/fungal infections. The narrowed and erythematous canal with white debris is characteristic of this condition. Otitis media (Choice A) typically presents with deep ear pain, hearing loss, and sometimes fever, but does not involve the ear canal. Perforation of the tympanum (Choice C) would present with sudden relief of pain and possible drainage from the ear. Cholesteatoma (Choice D) is characterized by a painless cyst or mass in the middle ear, not presenting with these acute ear canal symptoms.

Correct Answer: D

Rationale: The most likely explanation for the discrepancy between the patient's relatively normal blood pressure reading (118/92) and the presence of hypertensive changes in her retinas and mild proteinuria is that the process causing her retinopathy and kidney problems has resolved. Hypertensive changes in the retinas and proteinuria are typically signs of chronic uncontrolled hypertension, but they can also be residual manifestations of previously uncontrolled hypertension that has now been effectively treated.

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.
