Elsie Item-Writing Academy
About 45 minutes · Academy module: Foundations: Writing Shelf/Clerkship–Style Items
The Elsie Item-Writing Academy is an independent faculty-development resource. It is not affiliated with, endorsed by, or sponsored by the AAMC, NBME, USMLE, LCME, or NRMP. Completion of this module supports faculty-development documentation.
Shelf-style items follow the clinical subject examination pattern: five options, A through E, built on clinical vignettes, spanning seven clerkship banks — internal medicine, surgery, pediatrics, obstetrics and gynecology, family medicine, psychiatry, and neurology. The foundations from the other levels all carry over: one best answer, a focused lead-in, homogeneous and plausible options, no absolute terms, no "all of the above," no unemphasized negative stems, and the cover-the-options rule. What changes is the discipline framing. Each clerkship tests characteristic decision points, and the faculty author should aim the item at the decision the clerkship actually teaches.
Surgery items turn on the operative decision — operate now, observe, or obtain the study that changes the plan — and the discriminating data are usually stability, peritoneal signs, and time course. Pediatrics items turn on age-specific presentations and developmental context: the same symptom means different things at 3 months and 3 years, so the vignette must carry the age. Obstetrics and gynecology items turn on gestational-age branch points and stability: management pivots on weeks of gestation and on whether mother and fetus are stable. Internal medicine items reward breadth — diagnosis and management across systems with attention to comorbidity. Family medicine items favor the undifferentiated presentation and prevention. Psychiatry items turn on criterion-based diagnosis and safety assessment. Neurology items turn on localization — the examination finding that places the lesion.
Across all seven banks, the same authoring discipline applies: state the tested point first, write the key before the distractors, make every distractor a plausible near-miss from the same discipline's differential, and never let the stem echo the correct option's wording.
Concretely: a surgery item earns its keep when the examinee must weigh peritoneal signs against stability to choose between the operating room and further imaging — the vignette's job is to make that fork explicit. An obstetrics item earns its keep at the gestational-age branch: the same bleeding at 28 weeks and at 39 weeks resolves to different answers, so the weeks must be stated and the options must diverge on them. A pediatrics item earns its keep on age: the differential for stridor at 6 months is not the differential at 6 years, and the options should contain the near-miss from the adjacent age group. When the item's fork matches the clerkship's real fork, the drill teaches transferable judgment rather than trivia.
Source every distractor from the same bank's differential. A surgery distractor should be the operation's genuine alternative — the study that would change the plan, the nonoperative path with its own indications — not a medicine answer smuggled in. A psychiatry distractor should be the adjacent diagnosis separated by one criterion, because criterion-counting is the discipline's actual work. Cross-bank distractors test nothing; they fill space. The examinee should feel the clerkship's own reasoning pressure in every option, including the wrong ones.
A shelf item should read like the clerkship thinks: the surgery item should feel surgical, the pediatrics item should feel pediatric. When the discipline framing is right, the examinee recognizes the decision point before reaching the options — which is exactly what the cover-the-options rule demands.
(intended key: B)
Stem: A 68-year-old man hospitalized for small bowel obstruction develops fever, tachycardia, hypotension, involuntary guarding, and rebound tenderness — concerning for a surgical abdomen requiring operative exploration. What is the most appropriate next step?
A. Continue conservative management with nasogastric decompression B. Operative exploration of the surgical abdomen C. CT of the abdomen and pelvis D. Colonoscopy E. Discharge home with outpatient follow-up
clueing.
The stem announces "a surgical abdomen requiring operative exploration," and option B repeats it back as "operative exploration of the surgical abdomen." The examinee matches phrases instead of interpreting peritoneal signs — the surgical decision-making the item pretends to test never happens. Clueing is especially tempting in surgery items because the findings feel dramatic and the author wants to be sure the picture is clear. The discipline-correct fix: report the findings plainly (guarding, rebound, vitals, free air) and let the options carry the decision. The rewrite's key is earned by interpreting peritonitis with pneumoperitoneum, not by echoing the stem.
— cold-solve verified: 2/2 (solvers chose C, C)
Stem: A 68-year-old man is hospitalized for small bowel obstruction. He initially improves with nasogastric decompression and intravenous fluids, but on hospital day 2 he develops worsening diffuse abdominal pain. Vital signs: temperature 38.4°C, heart rate 114/min, blood pressure 96/60 mm Hg. Abdominal examination reveals involuntary guarding and rebound tenderness. An upright chest radiograph shows free air under the diaphragm. Which of the following is the most appropriate next step in management?
A. Continue nasogastric decompression and intravenous fluids B. Administer water-soluble oral contrast and obtain serial radiographs C. Proceed to exploratory laparotomy D. Obtain CT of the abdomen and pelvis with intravenous contrast E. Perform colonoscopy
Key: C
Peritonitis with hemodynamic instability and pneumoperitoneum means perforated viscus — a surgical emergency, and further imaging only delays the operating room. Continued conservative management and contrast challenge are for uncomplicated obstruction without peritonitis; CT is for ambiguous cases, not frank perforation with free air; colonoscopy has no role. Both independent cold solvers selected C and named no other defensible option.
(intended key: C)
Stem: A 3-year-old boy presents with 2 days of rhinorrhea and low-grade fever followed by abrupt onset of barky cough and inspiratory stridor, worse at night. He is nontoxic without drooling, and neck radiograph shows subglottic narrowing. Which of the following is not indicated in the initial management of this patient?
A. Nebulized racemic epinephrine B. Dexamethasone C. Intravenous ceftriaxone D. Observation for stridor at rest E. Cool mist
negative stem without emphasis.
The unemphasized "not" turns a straightforward pediatrics decision into a proofreading exercise — the examinee who knows croup management perfectly can still choose a correct therapy by misreading the question. Pediatrics items already demand close reading of ages and weights; the lead-in should not add a second trap. The rewrite asks the positive, discipline-true question: given this age and this presentation, what is the initial treatment? Note the rewrite also keeps the age-specific discriminators (3 years old, nontoxic, no drooling) that separate croup from epiglottitis at this age.
— cold-solve verified: 2/2 (solvers chose A, A)
Stem: A 3-year-old boy presents with a 2-day history of rhinorrhea and low-grade fever followed by the abrupt onset of a barky, seal-like cough and inspiratory stridor that worsen at night. He is nontoxic, with mild suprasternal retractions and no drooling. Neck radiograph shows subglottic narrowing. Which of the following is the most appropriate initial treatment?
A. Nebulized racemic epinephrine and a single dose of dexamethasone B. Intravenous ceftriaxone C. Emergent intubation in the operating room D. Nebulized albuterol E. Heliox therapy
Key: A
Barky cough, inspiratory stridor, and subglottic narrowing (steeple sign) in a nontoxic 3-year-old is croup, treated initially with nebulized racemic epinephrine plus dexamethasone. Ceftriaxone and emergent OR intubation belong to epiglottitis — the age-appropriate near-miss, excluded here by the nontoxic appearance and absent drooling. Albuterol targets lower-airway wheeze, not upper-airway edema; heliox is adjunctive, not initial. Both independent cold solvers selected A and named no other defensible option.
(intended key: A)
Stem: A 26-year-old woman, gravida 2 para 1, at 28 weeks' gestation presents with painless vaginal bleeding. Vitals are normal, the tracing is reassuring, and ultrasound shows complete placenta previa without contractions. What is the most appropriate next step?
A. Pelvic rest with expectant management and antenatal surveillance B. Immediate cesarean delivery C. Schedule delivery according to the lunar cycle D. Prescribe bed rest while standing on one foot E. Tocolysis with nifedipine
implausible distractors.
Options C and D are jokes, not distractors — no examinee at any level would select them, so the item is really a three-option question and teaches nothing about discriminating among plausible plans. Implausible distractors usually signal that the author ran out of real alternatives, which in OB/GYN often means the gestational-age branch point was not used: at 28 weeks stable, the genuine alternatives are delivery now versus expectant management, and the genuine dangers are vaginal examination and induction. The rewrite replaces the throwaways with those real near-misses, so each option tests whether the examinee applied the gestational-age and stability branch points.
— cold-solve verified: 2/2 (solvers chose A, A)
Stem: A 26-year-old woman, gravida 2 para 1, at 28 weeks' gestation presents with painless vaginal bleeding. Vital signs are normal, the fetal heart tracing is reassuring, and ultrasonography demonstrates a complete placenta previa. There are no contractions. Which of the following is the most appropriate next step in management?
A. Pelvic rest with expectant management and antenatal surveillance B. Immediate cesarean delivery C. Digital examination to assess cervical dilation D. Induction of labor E. Tocolysis with nifedipine
Key: A
Stable complete placenta previa at 28 weeks is managed expectantly with pelvic rest and surveillance; delivery is reserved for term or for bleeding that threatens mother or fetus. Digital cervical examination is contraindicated and dangerous with previa; induction is contraindicated by the previa itself; tocolysis has no indication without contractions. Both independent cold solvers selected A and named no other defensible option.
