Two dizygotic twins present to the university clinic because they believe they are being poisoned through the school's cafeteria food. They have brought these concerns up in the past, but no other students or cafeteria staff support this belief.

A geriatric investigator is evaluating the consistency of Alzheimer dementia diagnoses based on clinical symptoms.

The extent to which the diagnosis by one physician was replicated by another clinician examining the same patient is best described by which of the following terms?
AValidity
BSpecificity
CPredictive value

EPrecision
A 25-year-old man comes to the physician for severe back pain. He describes the pain as shooting and stabbing. On a 10-point scale, he rates the pain as a 9 to 10. The pain started after he lifted a heavy box at work; he works at a supermarket and recently switched from being a cashier to a storekeeper. The patient appears to be in severe distress. Vital signs are within normal limits. On physical examination, the spine is nontender without paravertebral muscle spasms. Range of motion is normal. A straight-leg raise test is negative. After the physical examination has been completed, the patient asks for a letter to his employer attesting to his inability to work as a storekeeper. Which of the following is the most appropriate response?
A“Yes. Since work may worsen your condition, I would prefer that you stay home a few days. I will write a letter to your employer to explain the situation.”
BYou say you are in severe pain. However, the physical examination findings do not suggest a physical problem that can be addressed with medications or surgery. I'd like to meet on a regular basis to see how you're doing.
CI understand that you are uncomfortable, but the findings do not match the severity of your symptoms. Let's talk about the recent changes at your job.
DThe physical exam findings do not match your symptoms, which suggests a psychological problem. I would be happy to refer you to a mental health professional.
EThe physical exam findings suggest a psychological rather than a physical problem. But there is a good chance that we can address it with cognitive-behavioral therapy.
