A 76-year-old retired farmer comes to your office complaining of abdominal pain, constipation, and a low-grade fever for about 3 days. He denies any nausea, vomiting, or diarrhea. The only unusual thing he remembers eating is two bags of popcorn at the movies with his grandson, 3 days before his symptoms began. He denies any other recent illnesses. His past medical history is significant for coronary artery disease and high blood pressure. He has been married for over 50 years. He denies any tobacco, alcohol, or drug use. His mother died of colon cancer and his father had a stroke. On examination he appears his stated age and is in no acute distress. His temperature is 9 degrees and his other vital signs are unremarkable. His head, cardiac, and pulmonary examinations are normal. He has normal bowel sounds and is tender over the left lower quadrant. He has no rebound or guarding. His rectal examination is unremarkable and his fecal occult blood test is negative. His prostate is slightly enlarged but his testicular, penile, and inguinal examinations are all normal. Blood work is pending. What diagnosis for abdominal pain best describes his symptoms and signs?

Correct Answer: A

Rationale: The most likely diagnosis for this patient's symptoms and signs is acute diverticulitis. His presentation of abdominal pain, constipation, and low-grade fever, along with tenderness over the left lower quadrant, is consistent with diverticulitis, which is inflammation or infection of small pouches (diverticula) that can develop in the colon. The history of recent onset of symptoms after consuming popcorn, typically a high-fiber food that can exacerbate diverticulitis, further supports this diagnosis. The negative fecal occult blood test makes more acute intra-abdominal processes like acute appendicitis less likely. Acute cholecystitis would present with right upper quadrant pain, and mesenteric ischemia typically presents with severe abdominal pain, nausea, and vomiting, as well as signs of abdominal distress.

Correct Answer: D

Rationale: The symptoms described in the scenario point towards pleural pain. The examination findings of normal breath sounds, no abnormalities with percussion and palpation of the chest, and a normal heart sound (S1 and S2) suggest that the issue is more likely related to the pleura rather than the heart or major blood vessels. Pleural pain is typically sharp and worsens with deep breathing or coughing. This differs from angina pectoris, which is chest pain caused by reduced blood flow to the heart muscles due to coronary artery disease. Pericarditis involves inflammation of the pericardium, the membrane surrounding the heart, and usually presents with chest pain that is relieved by sitting up and leaning forward. Dissecting aortic aneurysm is a life-threatening condition characterized by severe, tearing chest pain that can radiate to the back. In this case, the lack of significant abnormalities on cardiac and vascular examination points towards ple

Correct Answer: A

Rationale: The presentation of pain that is markedly worse when the left arm is drawn across the chest (adduction) is characteristic of a rotator cuff tear. This is because when the arm is adducted, it puts stress on the torn rotator cuff tendons, causing pain. In contrast, subacromial bursitis typically presents with pain during overhead movements, acromioclavicular joint involvement may present with pain localized to the joint itself, and adhesive capsulitis (frozen shoulder) typically presents with pain and stiffness that worsens with all movements.

Correct Answer: C

Rationale: Diplopia occurring when one eye is covered is a condition known as monocular diplopia. This symptom is typically not caused by problems within the eye itself, such as irregularities in the cornea or lens. Instead, monocular diplopia with one eye covered is more likely to be an indication of a neurological issue, often involving the brainstem. Lesions or damage in the brainstem can disrupt the normal coordination of eye movements, leading to the perception of double vision when one eye is closed. Weakness of CN III (oculomotor nerve) or CN IV (trochlear nerve) may cause diplopia when both eyes are open, but it would not typically manifest as monocular diplopia.

Correct Answer: D

Rationale: It is important to maintain a calm demeanor when walking into the examination room to speak with your first clinic patient, especially in a busy and high-pressure situation. Demonstrating calmness will help to build rapport with the patient, create a sense of trust, and promote effective communication. This demeanor will also convey professionalism and confidence, which are essential qualities for a healthcare provider. Displaying irritability, impatience, or boredom can negatively impact the patient-provider relationship and hinder effective communication, potentially compromising the quality of care provided.

Correct Answer: B

Rationale: When conducting a health history assessment, the components typically include the review of systems, present illness, and personal and social items. The review of systems involves asking specific questions related to each system of the body to gather comprehensive information about the patient's overall health. Present illness focuses on the current chief complaint and symptoms the patient is experiencing. Personal and social items encompass details such as lifestyle habits, family history, medical history, and social support systems. The thorax and lungs are typically assessed as part of the physical examination, not specifically in the health history documentation.

Correct Answer: A

Rationale: Mr. Kelly's scenario is consistent with the phenomenon called "white coat hypertension," where an individual's blood pressure readings are elevated in a medical setting due to anxiety or stress, but are normal when measured at home. This discrepancy between office and home readings is a key indicator of white coat hypertension. Additionally, the fact that Mr. Kelly has been consistently monitoring his blood pressure at home and has kept a log supports the likelihood that his elevated readings in the office are primarily due to the stress of being in that environment. It is important to acknowledge white coat hypertension as a common occurrence and not necessarily a reflection of true high blood pressure that requires immediate medical intervention.

Correct Answer: B

Rationale: The vertebral bodies of the spine involve cartilaginous joints. Cartilaginous joints are connected by cartilage, which allows for slight movement and flexibility. In the spine, the cartilaginous joints between vertebral bodies are called intervertebral discs. These discs act as shock absorbers and provide cushioning between each vertebra, helping to prevent bone-on-bone contact. In Mark's case, the presence of a bulging disc suggests that there is an issue with the cartilaginous joint between his vertebral bodies, leading to the compression of a spinal nerve and causing the burning pain down his right leg and slight foot drop.
