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?

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.

Correct Answer: B

Rationale: Mrs. Fletcher's symptoms of unilateral pain during chewing, which is chronic, without facial tenderness or tenderness of the scalp are more suggestive of temporomandibular joint (TMJ) syndrome rather than other conditions listed. TMJ syndrome is characterized by pain and dysfunction of the jaw muscles and the joints that connect the jaw to the skull. The pain is often worsened by chewing or opening the mouth widely. In this case, the absence of facial tenderness or signs of temporal arteritis makes these conditions less likely. Trigeminal neuralgia typically presents with sudden, severe facial pain in the distribution of the trigeminal nerve. Tumor of the mandible would likely present with other symptoms such as swelling, bone destruction, or difficulty with mouth opening and chewing. Temporal arteritis usually presents with symptoms such as headache, scalp tenderness, and visual disturbances. Given Mrs. Fletcher's presentation,

Correct Answer: B

Rationale: In an elderly woman with a history of coronary bypass surgery presenting with severe, diffuse abdominal pain that is not worsened by abdominal palpation, neuropathy should be suspected. Neuropathy refers to nerve damage, which can result in abnormal sensations of pain, often described as burning, shooting, or stabbing. Abdominal neuropathy can be caused by various conditions such as diabetes, alcohol abuse, vitamin deficiencies, or certain medications. The absence of worsening pain upon palpation makes organic abdominal pathology less likely, suggesting a neuropathic etiology. In this case, further evaluation and testing for neuropathy would be warranted.

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.

Correct Answer: B

Rationale: Urge incontinence, also known as overactive bladder, is characterized by a sudden and strong urge to urinate which is difficult to control. In this case, Mrs. LaFarge is unable to get to the bathroom quickly enough when she senses the need to urinate, which indicates a lack of control over the urge to urinate. This is typically caused by involuntary contractions of the bladder muscle. Stress incontinence, on the other hand, is leakage of urine during activities that increase intra-abdominal pressure, such as coughing or exercising. Overflow incontinence is characterized by urinary retention and constant dribbling of urine due to the bladder being unable to empty properly. Functional incontinence occurs when a person has normal bladder control but is unable to reach the bathroom in time due to physical or cognitive impairments. Since Mrs. LaFarge is experiencing a sudden and strong urge to urinate that she cannot

Correct Answer: A

Rationale: The area of the arm that drains to the epitrochlear nodes includes the ulnar surface of the forearm and hand, little and ring fingers, and the ulnar side of the middle finger. The epitrochlear nodes are located in the medial aspect of the arm above the elbow, close to the insertion of the biceps brachii muscle. These nodes receive lymphatic drainage from the above-mentioned areas and play a role in the immune response against infections in these regions.

Correct Answer: D

Rationale: To hear a soft murmur or bruit clearly, it is important to minimize any background noise or distractions that may interfere with your ability to auscultate effectively. Therefore, asking the patient to hold her breath (choice A) can help reduce noise caused by the patient's respiration. Asking the patient in the next bed to turn down the TV (choice B) can also help eliminate external noise that may disrupt your ability to hear subtle sounds. Checking your stethoscope for air leaks (choice C) is crucial to ensure that you are hearing sounds accurately and not being affected by any equipment issues. By combining these strategies, you can create an optimal environment for listening to soft murmurs or bruits.

Correct Answer: D

Rationale: The constellation of symptoms described in the scenario, including chronic constipation, fatigue, weight gain, irregular periods, cold intolerance, and delayed deep tendon reflexes, suggests hypothyroidism as the likely cause. Hypothyroidism is a condition where the thyroid gland does not produce enough thyroid hormones, leading to a slowdown in bodily functions. Constipation is a common symptom of hypothyroidism due to the decreased motility of the bowel. The presence of cold intolerance, weight gain, and irregular periods further supports this diagnosis, as these are classic symptoms of hypothyroidism. The delayed deep tendon reflexes, especially in the Achilles tendons, are indicative of the myopathic changes that can occur in hypothyroidism. It is important to further investigate thyroid function through laboratory testing to confirm the diagnosis and initiate appropriate treatment. Other conditions such as large bowel obstruction, irritable bowel syndrome, and rectal cancer are less likely based
