A 25-year-old accountant presents to your clinic, complaining of intermittent lower right- sided chest pain for several days. He describes it as knifelike and states it only lasts for 3 to 5 seconds, taking his breath away. He states he feels like he has to breathe shallowly to keep it from recurring. The only thing that makes it better is lying quietly on his right side. It is much worse when he takes a deep breath. He has taken some Tylenol and put a heating pad on his side but neither has helped. He remembers that 2 weeks ago he had an upper respiratory infection with a severe hacking cough. He denies any recent trauma. His past medical history is unremarkable. His parents and siblings are in good health. He has recently married, and his wife has a baby due in 2 months. He denies any smoking or illegal drug use. He drinks two to three beers once a month. He states that he eats a healthy diet and runs regularly, but not since his recent illness. He denies any cardiac, gastrointestinal, or musculoskeletal symptoms. On examination he is lying on his right side but appears quite comfortable. His temperature, blood pressure, pulse, and respirations are unremarkable. His chest has normal breath sounds on auscultation. Percussion of the chest is unremarkable. During palpation the ribs are nontender. What disorder of the chest best describes his symptoms?

Correct Answer: C

Rationale: The patient's symptoms of intermittent, sharp chest pain with breathing that worsens with deep breaths and is relieved by lying on the right side are suggestive of pleural pain. Pleuritic chest pain is often described as sharp or stabbing and occurs when the parietal pleura, the outer lining of the lungs, becomes inflamed or irritated. In this case, the patient's history of an upper respiratory infection with a severe hacking cough two weeks ago suggests that the pleural pain may be related to pleurisy or pleuritis, which can occur as a complication of respiratory infections.

Correct Answer: D

Rationale: When a woman over the age of 40 presents with a breast mass, the risk of the mass being cancerous is around 40%. This risk is higher in older women compared to younger women. It is important for Mrs. Patton to undergo further evaluation, which may include imaging tests, a biopsy, and consultation with a specialist to confirm the diagnosis and determine the appropriate treatment. It is crucial to address breast masses promptly to ensure timely management and optimal outcomes.

Correct Answer: B

Rationale: Dakota's presentation of a rash with small, bright red marks that do not fade when pressed (non-blanching) along with a slight fever raises concern for a serious condition such as meningococcal infection. Non-blanching rashes, especially when associated with fever, can be a sign of meningococcal sepsis, a life-threatening condition that requires urgent medical attention. Admission to the hospital is warranted for close monitoring, further evaluation, and initiation of appropriate treatment if needed. It is important to err on the side of caution in such cases to ensure the best possible outcome for the patient.

Correct Answer: B

Rationale: Asymmetric blood pressures (BPs) refer to a significant difference in blood pressures between the two arms. This is commonly seen in conditions like congenital narrowing of the aorta, also known as coarctation of the aorta. In this condition, there is a localized narrowing of the aorta, leading to higher blood pressure in the upper extremities compared to the lower extremities. This results in a significant asymmetry in blood pressure readings between the arms. It is crucial to identify this sign as it can have important diagnostic and treatment implications.

Correct Answer: B

Rationale: The description provided, "It is accompanied by nausea and vomiting. It is located in the mid-epigastric area," indicates the current symptoms and location of the discomfort the patient is experiencing. This information is typically included in the Present Illness section of a medical history, which focuses on the patient's current health concerns, symptoms, and complaints. It helps the healthcare provider understand the nature of the problem and guide further evaluation and treatment. The Chief Complaint is usually a concise statement of the patient's main reason for seeking medical attention, the Personal and Social History includes information about the patient's lifestyle habits and social support, and the Review of Systems is a systematic inquiry about the patient's overall health.
