You are excited about a positive test finding you have just noticed on physical examination of your patient. You go on to do more examination, laboratory work, and diagnostic tests, only to find that there is no sign of the disease you thought would correlate with the finding. This same experience happens several times. What should you conclude?
- A. Consider not doing this test routinely.
- B. Use this test when you have a higher suspicion for a certain correlating condition.
- C. Continue using the test, perhaps doing less laboratory work and diagnostics.
- D. Omit this test from future examinations.
Correct Answer: B
Rationale: The repeated scenario of finding a positive test result that does not correlate with the suspected disease indicates a lack of specificity for the test in question. In such cases, it is important to use the test when there is a higher suspicion for a specific condition that is known to correlate with the finding. By using the test selectively in situations where it is more likely to provide accurate information, its utility can be maximized and unnecessary further workup can be avoided. This approach allows for a more targeted and efficient use of resources in the diagnostic process.

A 23-year-old graduate student comes to your clinic for evaluation of a urethral discharge. As the provider, you need to get a sexual history. Which one of the following questions is inappropriate for eliciting the information?
- A. Are you sexually active?
- B. When was the last time you had intimate physical contact with someone, and did that contact include sexual intercourse?
- C. Do you have sex with men, women, or both?
- D. How many sexual partners have you had in the last 6 months?
Correct Answer: B
Rationale: While it is important to ask about recent sexual activity and whether it included sexual intercourse, using the term "intimate physical contact" is not specific enough. This question could potentially lead to misinterpretation or confusion regarding what types of activities are being referred to. It is more appropriate to directly ask about sexual intercourse when obtaining a sexual history. The other options are all appropriate questions to elicit information about the patient's sexual history.
His abdominal examination is normal. Visualization of the anus shows no masses, inflammation, or fissures. Digital rectal examination reveals a warm, boggy, tender prostate. No discrete masses are felt and there is no blood on the glove. The scrotum and penis appear normal. Urinalysis shows moderate amounts of white blood cells and bacteria. What disorder of the anus, prostate, or rectum best describes this situation?
- A. Benign prostatic hyperplasia (BPH)
- B. Prostatitis
- C. Prostate cancer
- D. Epididymitis
Correct Answer: B
Rationale: Prostatitis is the most likely disorder based on the symptoms described. The warm, boggy, tender prostate upon digital rectal examination, along with the presence of moderate white blood cells and bacteria in the urinalysis, suggests an inflammatory condition of the prostate. In this case, there are no signs of masses or blood in the rectal examination, which would be more indicative of prostate cancer. Epididymitis typically presents with symptoms involving the scrotum and may be associated with testicular pain and swelling, which are not described in this scenario. Benign prostatic hyperplasia (BPH) is a nonmalignant enlargement of the prostate gland that typically presents with symptoms of urinary urgency, frequency, and nocturia, rather than the inflammatory signs seen in this case.
You ask a patient to draw a clock. He fills in all the numbers on the right half of the circle. What do you suspect?
- A. Hemianopsia
- B. Fatigue
- C. Oppositional defiant disorder
- D. Depression
Correct Answer: A
Rationale: Filling in all the numbers on just one side of the clock when asked to draw a clock suggests a visual field deficit, typically seen in hemianopsia. Hemianopsia is a visual impairment where half of the visual field is lost due to neurological damage or injury, such as a stroke. This causes the individual to have difficulty perceiving or attending to objects in the affected visual field. In this case, the patient's right visual field may be affected, leading to the specific pattern of filling numbers on the right half of the clock. It is essential to further assess and refer the patient for a complete visual field evaluation and neurological examination.
Mr. Jackson is a 50-year-old African-American who has had discomfort between his scrotum and anus. He also has had some fevers and dysuria. Your rectal examination is halted by tenderness anteriorly, but no frank mass is palpable. What is your most likely diagnosis?
- A. Prostate cancer
- B. Colon cancer
- C. Prostatitis
- D. Colonic polyp
Correct Answer: C
Rationale: The most likely diagnosis in this case is prostatitis. Prostatitis is the inflammation or infection of the prostate gland, which can cause symptoms such as discomfort between the scrotum and anus (perineum), fevers, and dysuria (painful urination). The tenderness anteriorly during rectal examination is consistent with prostatitis as the prostate gland is located in front of the rectum and can be tender to touch when inflamed. Prostate cancer typically presents with symptoms such as urinary frequency, nocturia, hematuria, or bone pain, and is less likely to cause the symptoms described in this scenario. Colon cancer and colonic polyps are less likely as they would not typically cause discomfort in the perineal area or dysuria.
It started a few hours ago, and she has noted nausea with sensitivity to light; she has had headaches like this in the past, usually less than one per week, but not as severe. She does not know of any inciting factors. There has been no change in the frequency of her headaches. She usually takes an over- the-counter analgesic, and this results in resolution of the headache. Based on this description, what is the most likely diagnosis of the type of headache?
- A. Tension
- B. Migraine
- C. Cluster
- D. Analgesic rebound
Correct Answer: B
Rationale: The description of the headache as starting a few hours ago, associated with nausea, sensitivity to light, and being severe in intensity suggests a migraine headache. Migraine headaches are often accompanied by these symptoms, known as migraine features. The fact that the patient experiences headaches like this less than once a week and typically uses over-the-counter analgesics to relieve them is also suggestive of migraines. Tension headaches typically present as a more mild to moderate, band-like pressure around the head, without the associated symptoms of nausea and sensitivity to light. Cluster headaches are characterized by excruciating pain around one eye, often accompanied by other symptoms like redness or tearing in the eye. Analgesic rebound headaches occur due to overuse of pain medications and typically present as daily headaches that improve with the same medication that caused them in the first place.
