Q500. Patient hurts his knee, causing him the ability to bend his leg inward to a greater extent then normally possible. What structure is damaged?
A500. Lateral Collateral Ligament; (Varus test)
Q501. Patient hurts his knee, causing him the ability to bend his leg outward to a greater extent then normally possible. What structure is damaged?
A501. Medial Collateral Ligament; (Valgus test)
Q502. Patient hurts his knee, causing him to feel loose intra- articular bodies and a locking of the knee. What structure is damaged?
A502. Medial Meniscus
Q503. What is the first step in the evaluation of a palpable thyroid nodule?
A503. Ultrasound
Q504. A front-seat passenger in a car involved in a head-on collision relates that he hit the dashboard with his knees, however, he is specifically complaining of severe pain in his right hip, rather than knee pain. He lies in the stretcher in the emergency department with the right lower extremity shortened, adducted, and internally rotated. What is the most likely injury?
A504. Posterior dislocation of the hip; (not fracture of the femoral neck)
Q505. A 25-year-old man is shot with a .22 caliber revolver. The entrance wound is in the anteromedial aspect of his upper thigh, and the exit wound is about 3 inches lower, in the posterolateral aspect of the thigh. He has a large, expanding hematoma in the upper inner thigh. There are no palpable pulses in the foot. The bone is intact by physical examination and x-ray films. What is the most appropriate next step in management?
A505. Surgical Exploration; (Arteriograms are very often used in vascular trauma, but are not needed here. We would use an arteriogram if the anatomic location of the injury suggested vascular involvement, but the clinical signs did not confirm such suspicion. Arteriograms are also used when the specific surgical approach is dictated by precise knowledge of the site of extravasation, a situation that does not apply here)
Q506. A 7-year-old boy passes a large, bloody bowel movement. He is hemodynamically stable, and he has a hemoglobin of 14 g/dL. Nasogastric aspiration yields clear, greenish fluid. Physical examination, including anoscopy, is unremarkable. What is the most appropriate next diagnostic test?
A506. Radioactively labeled Technetium Scan; (In this age group, with no obvious anal pathology and negative gastric aspirate, the leading cause of gastrointestinal bleeding is Meckel's diverticulum. The specific source is ulceration of the normal ileal mucosa by acid produced by gastric mucosa in the diverticulum. The technetium scan identifies that ectopic gastric mucosa. Upper gastrointestinal endoscopy would have been appropriate if the gastric aspirate had produced blood)
Q507. An 81-year-old man with Alzheimer disease who lives in a nursing home undergoes surgery for a fractured femoral neck. On the 5th postoperative day, it is noted that his abdomen is grossly distended and tense, but not tender; no evidence of occult blood. X-ray films show a few distended loops of small bowel and the gas pattern of distention extends throughout the entire large bowel, including the sigmoid and rectum. No stool is seen in the films. Otherwise he does not appear to be ill. Vital signs are normal for his age. What is the most likely diagnosis?; Diagnostic test?; Tx?
A507. Dx: Ogilvie Syndrome; (a type of colonic dysfunction often seen in elderly patients who are not too active to begin with and are then further immobilized by extra-abdominal surgery); Diagnostic test: Colonoscopy; (rules out obstructing cancer, which is always a consideration in this age group, and allows the gas to be sucked out as the instrument advances); Tx: A long tube is then left in place
Q508. A 42-year-old, right-handed man has had a history of progressive speech difficulties and right hemiparesis for 5 months. He has had progressively severe headaches for the past 2 months, which are worse in the mornings. At the time of admission, he is confused and vomiting, and has blurred vision, papilledema, and diplopia. Shortly thereafter, his blood pressure increases to 190/110 mm Hg, and he develops bradycardia. What is most likely the significance of the hypertension and the bradycardia?
A508. There is a near-terminal increase in intracranial pressure; (the development of hypertension and bradycardia (Cushing's reflex) signifies that the brain has run out of compensatory mechanisms to minimize the intracranial pressure elevation generated by increased intracranial volume. When that point is reached, brain perfusion suffers and death is imminent)
Q509. On the 5th postoperative day, it is noticed that large amounts of clear, pink, salmon-colored fluid are soaking the wound dressings. The incision appears intact and not particularly red or inflamed, but there are indeed traces of the clear pink fluid on his skin. He has no specific complaints. He is still NPO and on IV fluids, but has already been passing gas per rectum, and plans had been made to feed him today. The abdomen is not distended, and he has normal bowel sounds. He is afebrile. What is the most appropriate next step in management?
A509. Tape the wound securely, bind the abdomen, and avoid events that would suddenly increase his intra-abdominal pressure; (The situation described is that of a wound dehiscence that has not yet progressed to a wound evisceration. The former can be dealt with at leisure, if the latter is avoided. He will eventually require re-closure, but it can be done whenever it is most convenient. Remember: Pink fluid on an abdominal surgical wound is a leak of intra-abdominal fluid)
Q510. A 24-year-old woman sustains multiple injuries in a car accident, including a pelvic fracture. She is hemodynamically stable. Initial assessment shows no vaginal or rectal injuries; however, when a Foley catheter is inserted, bloody urine is recovered. What would be the best way to evaluate her urologic injury?
A510. Retrograde cystogram including post-void films; (it is important to include post-void films because extravasation at the bladder neck can be obscured by the dye that is filling the bladder)
Q511. A 62-year-old woman has a 4-cm, hard mass under the nipple and areola of her rather small left breast. The mass occupies most of the breast, but the breast is freely movable from the chest wall. There is no dimpling or ulceration of the skin over the mass, and careful palpation of the axilla is completely negative. A core biopsy of the breast mass has established a diagnosis of infiltrating ductal carcinoma, and the mammogram showed no other lesions in that breast or the other one. A chest x-ray film and liver function tests are normal. She has no symptoms suggestive of brain or bone metastasis. What Tx should be offered to this woman?
A511. Modified Radical Mastectomy including axillary sampling; (Lumpectomy, axillary sampling, and post-op radiation would have been the correct answer for a smaller tumor in a larger breast)
Q512. A 49-yo obese man presents with a serum calcium of 14. He has uncontrolled DM and bipolar disorder (for which he takes lithium). What is the most likely cause of the calcium elevation?
A512. Parathyroid Hyperplasia secondary to Renal Failure from the uncontrolled DM; (when the kidney loses its ability to reabsorb calcium and Vit D, hypocalcemia triggers the parathyroid gland to increase their production of parathyroid hormone)
Q513. A 5-yo boy is brought to the ER after ingesting a half-bottle of liquid drain cleaner. What is the next step?
A513. Tracheostomy; (even though the step doesn’t state a breathing problem, airway edema, stridor and difficulty breathing is likely)
