Elias Bergman, a 52-year-old male in the surgical recovery ward, complains of nausea.
Case details
Patient Demographics
Name: Elias Bergman
Age: 52 years
Gender: Male
Occupation: Veterinarian
Living Situation: Lives with spouse and two adult children
History of Presenting Complaint
Elias Bergman underwent an elective laparoscopic cholecystectomy under general anesthesia 6 hours ago. Initially asymptomatic post-operatively, he developed nausea and 3 episodes of non-bilious vomiting starting 3 hours after surgery. He reports:
- No hematemesis or abdominal pain beyond expected surgical site discomfort
- No fever/chills, chest pain, or neurological symptoms
- Symptoms worsen with attempts to sip water
Key detail: Received morphine for post-op pain 1 hour before symptom onset.
Past Medical History
- Hypertension (10 years, well-controlled)
- Type 2 Diabetes (HbA1c 7.2% on oral agents)
- GERD (diagnosed 5 years ago)
- No prior surgeries or anesthesia complications
Medications
Home:
- Metformin 1000mg BID (last dose 12h pre-op)
- Atenolol 50mg daily
- Omeprazole 20mg daily
Current:
- IV morphine 2mg PRN (given once)
- IV acetaminophen q6h
Allergies
NKDA (No known drug allergies)
Social History
- Never smoker
- Alcohol: 1-2 beers/week
- Sedentary occupation
- No recreational drug use
Family History
- Father: Type 2 Diabetes, CAD (MI at 65)
- Mother: Hypertension
- No family history of malignant hyperthermia or anesthesia complications
Examination Findings
General: Mild distress, dry mucous membranes.
Vitals: BP 128/82, HR 84, RR 18, SpO2 97% RA, Temp 37.1°C.
Abdomen:
- 4 small laparoscopic incisions with mild erythema
- Soft, minimal tenderness at port sites
- Active bowel sounds in all quadrants
- No rebound/guarding
Investigation Results
Labs (post-op):
- Normal CBC, electrolytes, LFTs
- Glucose 148 mg/dL
Imaging:
- CXR: Normal post-op findings
- EKG: Sinus rhythm, no acute changes
Actor Instructions
- Portray mild anxiety about vomiting again
- Frequently swallow as if nauseated
- Guard abdominal movement when sitting up
- Ask twice about when oral intake can resume
- Mention concern this might delay discharge
Red Flags
Must identify:
- Opioid-induced nausea (timing after morphine)
- Early dehydration signs (dry mucous membranes)
- Need for diabetes management adjustment
Trap: Missing non-PONV causes (e.g., early bowel obstruction).
Expected Approach
- Detailed timeline linking symptoms to anesthesia/analgesia.
- Assess hydration status and diabetes control.
- Differentiating PONV from other causes.
- Propose antiemetic regimen with monitoring plan.
- Address patient's concerns about recovery timeline.
Common Pitfalls
- Not asking about opioid administration timing
- Overlooking GERD as contributing factor
- Failing to plan for diabetic diet advancement
- Not considering multimodal antiemetic approach
- Missing opportunity for PONV prophylaxis education

27 pts available
History of Presenting Complaint
5 pts available
-
Clarifies timing and onset of nausea/vomiting relative to surgery and medication administration
1 ptsLinks symptom onset with perioperative events and morphine use, aiding in identifying likely causes (e.g., opioid-induced PONV).
-
Asks about frequency, volume, and appearance of vomitus (including bile or blood)
1 ptsDistinguishes benign PONV from complications such as GI bleeding or obstruction; essential for risk stratification.
-
Enquires about aggravating/relieving factors (e.g., relationship to oral intake, position)
1 ptsHelps differentiate between functional causes and surgical complications and guides supportive care.
-
Screens for associated symptoms (abdominal pain beyond surgical site, fever, chills, chest pain, neurological symptoms)
1 ptsIdentifies red flags for more serious complications such as infection, cardiac events, or CNS causes.
-
Asks about ability to tolerate oral fluids and presence of dehydration symptoms
1 ptsAssesses severity and risk of complications such as electrolyte imbalance or pre-renal AKI.
Past Medical History, Medications, and Allergies
3 pts available
-
Identifies relevant past medical history (e.g., diabetes, GERD, history of PONV or motion sickness)
1 ptsRecognizes risk factors for PONV and comorbidities that might affect management/safety of anti-emetics.
-
Reviews current regular and perioperative medications (including opioids, anti-emetics, and home medications)
1 ptsAssesses for medications contributing to symptoms or interactions with proposed treatments.
-
Inquires about drug allergies and adverse reactions
1 ptsPrevents administration of contraindicated medications, especially anti-emetics.
Physical Examination
5 pts available

Performs general inspection for distress, dehydration (dry mucous membranes, reduced skin turgor), and overall appearance
1 ptsAssesses severity of illness and need for urgent intervention.
-
Measures and interprets full vital signs (HR, BP, RR, temperature, O2 saturation)
1 ptsDetects systemic illness, infection, or signs of shock.
-
Inspects the surgical site for signs of infection or complications (erythema, swelling, discharge)
1 ptsEarly identification of wound-related complications.
-
Performs focused abdominal examination (palpation for tenderness, guarding, peritonism, auscultation for bowel sounds)
1 ptsAssesses for post-op ileus, peritonitis, or intra-abdominal complications.
-
Assesses for evidence of fluid status (e.g., capillary refill, peripheral pulses, JVP)
1 ptsIdentifies dehydration, volume depletion, or possible fluid overload.

Considers less common but serious complications (bowel obstruction, intra-abdominal sepsis, aspiration, myocardial infarction)
1 ptsShows ability to recognize rare but high-risk complications for early intervention.
-
Provides rationale based on clinical findings for most likely diagnosis
