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: A

Rationale: The carotid pulse is typically palpable, meaning that you can feel it when you place your fingers lightly on the carotid artery located in the neck. In contrast, jugular venous pulsation is not typically palpable. When examining jugular venous pulsation, it is important to differentiate it from the carotid pulse by considering factors such as the quality of pulsation, response to pressure, and changes with position.

Correct Answer: C

Rationale: The upstroke of the "a" wave in the jugular venous pulsations coincides with systole. The "a" wave is caused by atrial contraction, which occurs during ventricular systole. In contrast, the "x" descent is a diastolic phenomenon representing the atrial relaxation, the "y" descent follows atrial emptying in early diastole, and the "v" wave corresponds to venous filling during late diastole.

Correct Answer: D

Rationale: In a patient with emphysema, lung hyperinflation can make it difficult to hear heart sounds anteriorly. Listening posteriorly, especially between the scapulae, can often provide a clearer auscultation of the heart sounds due to reduced interference from lung sounds. The posterior approach can also help avoid any abdominal sounds that might obscure the cardiac sounds when auscultating in the epigastrium. It is important to make sure the patient is in a comfortable position for better examination, and in this case, listening posteriorly would be the best choice for assessing heart sounds in a patient with emphysema in exacerbation.

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.
