Correct Answer: B

Rationale: The description provided by Alexandra includes information about the location (right upper quadrant), intensity (3 to 8 on a scale), duration (2 to 3 hours), periodicity (coming and going, worse after eating), exacerbating factors (greasy foods), frequency (initially once a week, now every other day), and aggravating factors (nothing makes it better). However, there is no mention of any associated manifestations such as nausea, vomiting, fever, or other symptoms that may be occurring alongside the abdominal pain. Associated manifestations are important for a comprehensive assessment and differential diagnosis of the symptom.

Correct Answer: D

Rationale: In this patient with bilateral back pain that awakens him at night, the most reassuring finding is that the pain is bilateral. Bilateral symptoms are less likely to be associated with red flags such as malignancy or infection compared to unilateral symptoms. While back pain in individuals over the age of 50, pain at night, and pain lasting more than 1 month are concerning features, the fact that the pain in this patient is bilateral provides some reassurance. However, further evaluation is still warranted to determine the exact cause of the pain and appropriate management.

Correct Answer: B

Rationale: The policewoman's presentation of severe left-sided back pain radiating down into her groin, associated with nausea, blood in urine, and tenderness just inferior to the left costovertebral angle is highly suggestive of a kidney stone causing ureteral colic. Kidney stones are solid masses made of crystals that form in the kidneys and can cause sudden severe pain as they move through the urinary tract, leading to blockage and subsequent stretching of the ureter (the tube connecting the kidney to the bladder), resulting in pain that radiates from the flank down to the groin region. The presence of blood in the urine (hematuria) is a common finding with kidney stones due to irritation and damage to the ureteral lining as the stone passes. The negative urine pregnancy test rules out pregnancy-related causes of urinary symptoms. Musculoskeletal pain is less likely given the location and character of the pain

Correct Answer: D

Rationale: When assessing a patient for peripheral vascular disease in the arms, it is important to examine the pulses in the upper extremities. The pulses to be assessed in this context include the radial pulse (located on the wrist at the base of the thumb) and the brachial pulse (located in the upper arm near the elbow). These pulses provide important information about blood flow and circulation in the arms. Changes in the strength, regularity, or absence of these pulses can indicate potential issues related to peripheral vascular disease. While the femoral and popliteal pulses (Choice A) are important for assessing the lower extremities, and the dorsalis pedis and posterior tibial pulses (Choice B) are also crucial for evaluating peripheral vascular disease in the legs, the radial and brachial pulses are specifically relevant for assessing the arms. The carotid pulse (Choice C) is important for evaluating the vascular status of

Correct Answer: C

Rationale: The most likely pathologic process in this scenario is degenerative. The history provided includes chronic intermittent neck pain that worsened after a specific activity (wallpapering) but resolved with rest. The patient's age (47 years old) is also suggestive of degenerative changes in the spine. Additionally, the use of over-the-counter medications to manage the pain points towards a chronic condition such as degenerative changes in the cervical spine, possibly cervical spondylosis or osteoarthritis. There is no mention of any infectious symptoms, trauma, or neoplastic features in the presentation.
