A 28-year-old soldier is brought back to a military treatment facility 45 minutes after sustaining injuries in a building fire from a mortar attack. He was trapped inside the building for around 20 minutes. On arrival, he is confused and appears uncomfortable. He has a Glasgow Coma Score of 13. His pulse is 113/min, respirations are 18/min, and blood pressure is 108/70 mm Hg. Pulse oximetry on room air shows an oxygen saturation of 96%. Examination shows multiple second-degree burns over the chest and bilateral upper extremities and third-degree burns over the face. There are black sediments seen within the nose and mouth. The lungs are clear to auscultation. Cardiac examination shows no abnormalities. The abdomen is soft and nontender. Intravenous fluid resuscitation is begun. Which of the following is the most appropriate next step in management?

Intubation and mechanical ventilation

Insertion of nasogastric tube and enteral nutrition

Intravenous corticosteroid therapy

A mother presents to the family physician with her 16-year-old son. She explains, "There's something wrong with him doc. His grades are getting worse, he's cutting class, he's gaining weight, and his eyes are often bloodshot." Upon interviewing the patient apart from his mother, he seems withdrawn and angry at times when probed about his social history. The patient denies abuse and sexual history. What initial test should be sent to rule out the most likely culprit of this patient's behavior?

Sexually transmitted infection (STI) testing

A 43-year-old woman presents to her primary care physician with complaints of mild shortness of breath and right-sided chest pain for three days. She reports that lately she has had a nagging nonproductive cough and low-grade fevers. On examination, her vital signs are: temperature 99.1 deg F (37.3 deg C), blood pressure is 115/70 mmHg, pulse is 91/min, respirations are 17/min, and oxygen saturation 97% on room air. She is well-appearing, with normal work of breathing, and no leg swelling. She is otherwise healthy, with no prior medical or surgical history, currently taking no medications. The attending has a low suspicion for the most concerning diagnosis and would like to exclude it with a very sensitive though non-specific test. Which of the following should this physician order?

Obtain spiral CT chest with IV contrast

Order a lower extremity ultrasound

Obtain ventilation-perfusion scan

A 72-year-old woman comes to the emergency department because of upper abdominal pain and nausea for the past hour. The patient rates the pain as an 8 to 9 on a 10-point scale. She has had an episode of nonbloody vomiting since the pain started. She has a history of type 2 diabetes mellitus, hypertension, and osteoporosis. The patient has smoked 2 packs of cigarettes daily for 40 years. She drinks 5–6 alcoholic beverages daily. Current medications include glyburide, lisinopril, and oral vitamin D supplements. Her temperature is 38.5°C (101.3°F), pulse is 110/min, and blood pressure is 138/86 mm Hg. Examination shows severe epigastric tenderness to palpation with guarding but no rebound. Ultrasonography of the abdomen shows diffuse enlargement of the pancreas; no gallstones are visualized. The patient is admitted to the hospital for pain control and intravenous hydration. Which of the following is the most appropriate next step in the management of this patient’s pain?

Patient-controlled intravenous hydromorphone

Transdermal fentanyl every 72 hours

Oral acetaminophen every 6 hours

Transdermal bupivacaine on request

A 72-year-old woman is brought to the emergency department with dyspnea for 2 days. She is on regular hemodialysis at 3 sessions a week but missed her last session due to an unexpected trip. She has a history of congestive heart failure. After urgent hemodialysis, the patient’s dyspnea does not improve as expected. The cardiologist is consulted. After evaluation of the patient, he notes in the patient’s electronic record: “the patient does not have a chronic heart condition and a cardiac cause of dyspnea is unlikely.” The following morning, the nurse finds the cardiologist’s notes about the patient not having congestive heart failure odd. The patient had a clear history of congestive heart failure with an ejection fraction of 35%. After further investigation, the nurse realizes that the cardiologist evaluated the patient’s roommate. She is an elderly woman with a similar first name. She is also on chronic hemodialysis. To prevent similar future errors, the most appropriate strategy is to use which of the following?

Two patient identifiers at every patient encounter by any healthcare provider

Two patient identifiers at every nurse-patient encounter

A patient’s medical identification number at every encounter by any healthcare provider

Two patient identifiers at every physician-patient encounter

A patient’s medical identification number at every physician-patient encounter

A student health coordinator plans on leading a campus-wide HIV screening program that will be free for the entire undergraduate student body. The goal is to capture as many correct HIV diagnoses as possible with the fewest false positives. The coordinator consults with the hospital to see which tests are available to use for this program. Test A has a sensitivity of 0.92 and a specificity of 0.99. Test B has a sensitivity of 0.95 and a specificity of 0.96. Test C has a sensitivity of 0.98 and a specificity of 0.93. Which of the following testing schemes should the coordinator pursue?

Test C on the entire student body followed by Test A on those who are positive

Test A on the entire student body followed by Test B on those who are positive

Test A on the entire student body followed by Test C on those who are positive

Test C on the entire student body followed by Test B on those who are positive

Test B on the entire student body followed by Test A on those who are positive

A 27-year-old soldier is brought to the emergency department of a military hospital 20 minutes after being involved in a motor vehicle accident during a training exercise. He was an unrestrained passenger. On arrival, he has shortness of breath and chest pain. He appears pale and anxious. His temperature is 37°C (98.6°F), pulse is 110/min, respirations are 20/min, and blood pressure is 100/65 mm Hg. He is alert and oriented to person, place, and time. Examination shows pale conjunctivae and mucous membranes. There is bruising on the chest, extremities, and abdomen. The lungs are clear to auscultation. He has normal heart sounds and flat neck veins. The abdomen is flat, soft, and mildly tender. The remainder of the physical examination shows no abnormalities. High-flow oxygen is applied, and intravenous fluid resuscitation is begun. A chest x-ray is obtained. Which of the following is the most appropriate next step in management?

CT scan of the chest with contrast

Intubation with positive pressure ventilation

A 65-year-old man is admitted to the hospital because of a 1-month history of fatigue, intermittent fever, and weakness. Results from a peripheral blood smear taken during his evaluation are indicative of possible acute myeloid leukemia. Bone marrow aspiration and subsequent cytogenetic studies confirm the diagnosis. The physician sets aside an appointed time-slot and arranges a meeting in a quiet office to inform him about the diagnosis and discuss his options. He has been encouraged to bring someone along to the appointment if he wanted. He comes to your office at the appointed time with his daughter. He appears relaxed, with a full range of affect. Which of the following is the most appropriate opening statement in this situation?

What is your understanding of the reasons we did bone marrow aspiration and cytogenetic studies?

Your lab reports show that you have an acute myeloid leukemia

You must be curious and maybe even anxious about the results of your tests.

I may need to refer you to a blood cancer specialist because of your diagnosis. You may need chemotherapy or radiotherapy, which we are not equipped for.

Would you like to know all the details of your diagnosis, or would you prefer I just explain to you what our options are?

Efficient order entry strategies for USMLE Step 2 CK: High-Yield CCS Cases Lessons

Order Entry - Your Scoring Engine

Think, then act: Mentally batch orders before clicking. Prioritize interventions that stabilize the patient or yield critical data first.
Urgency is key: Differentiate orders correctly.
- Stat: Immediate, life-saving (e.g., defibrillation, stat ECG).
- Now: Within the hour (e.g., urgent labs, IV fluids).
- Routine: Scheduled (e.g., daily medications).
Logical Grouping: Bundle related orders (e.g., all admission labs, "sepsis panel"). This prevents omissions and saves precious seconds.

⭐ Pearl: When managing pain or nausea, always enter orders for analgesics/antiemetics with the diagnostic/therapeutic order, not after the patient complains. Anticipate and treat.

Workflow Wizardry - Taming the Clock

Mastering the Computerized Physician Order Entry (CPOE) system is key to saving precious minutes in a CCS case. Seconds saved on clicks translate to more time for patient management and decision-making.

Order Sets are Your Best Friend:
- Utilize pre-built protocols for common presentations like ACS, Stroke, Sepsis, or DKA.
- These bundle necessary labs, imaging, meds, and consults into a single click.
- Reduces cognitive load and prevents missed critical orders.
Strategic Batching:
- Group related orders. Don't enter labs one by one.
- Example: "Admission Orders" (Diet, VTE prophylaxis, code status) or "Initial Labs" (CBC, CMP, Coags).
Anticipate & Pre-order:
- If a diagnosis is highly likely, order ahead.
- E.g., Ordering blood products (group & screen) for a patient with a significant GI bleed before the Hb result is back.

⭐ CPOE systems with well-designed order sets can reduce ordering time by over 50% and significantly decrease medication errors compared to manual entry.

Common Traps - Sidestep & Score

Premature Orders: Avoid ordering tests before completing a focused history and physical exam. Initial data guides efficient, high-yield choices.
"Shotgun" Testing: Never order a massive, unfocused panel of tests. This wastes time, incurs penalties, and signals diagnostic uncertainty. Always be hypothesis-driven.
Forgetting Follow-ups: Failing to order serial vitals, repeat labs (e.g., troponins, ABG), or imaging to monitor the patient's response to treatment is a major pitfall.
Ignoring Test Hierarchy: Don't jump to invasive or expensive tests like CT/MRI when a cheaper, faster, or safer test (e.g., X-ray, Ultrasound) can provide the initial answer.
The "2-Minute Warning" Panic: This is not a cue to order everything. Use this time to finalize critical actions and move the patient to the correct disposition (e.g., "Admit to Ward," "Discharge Home").

⭐ Clock Management Pearl: The case clock pauses while the order entry window is open. Use this static time to calmly think, review, and batch your next set of actions without losing a single second of case time.

High‑Yield Points - ⚡ Biggest Takeaways

Prioritize ABCs: Always address Airway, Breathing, and Circulation with your first set of orders.

Group initial orders: Combine "IV, O2, Monitor" with essential labs like CBC, BMP, and LFTs.

Be specific, not vague: Order "Morphine 2 mg IV," not just "pain medication," to avoid system delays.

Confirm your differential: Order key diagnostic tests and specialist consults early to save crucial time.

Batch related orders: Enter all lab requests together, then all imaging, to improve workflow.

Manage the clock: Use "Advance clock" for results and "End Case" only after final disposition.
