# Clinical Cases: Clinical Skills for the Intern

## Case 1: Responding to an Urgent Page

### Case Presentation
A 29-year-old male internal medicine intern is paged at 2 AM for a 68-year-old male patient with new-onset hypotension (BP 82/54 mmHg). The patient was admitted for community-acquired pneumonia and had been stable. Using a systematic approach, the intern triages this as an emergent page requiring immediate bedside evaluation. Upon arrival, he assesses airway (patent), breathing (tachypneic at 24/min, SpO2 89% on room air), and circulation (tachycardic at 112 bpm, cool extremities, delayed capillary refill). He immediately applies supplemental oxygen, establishes IV access, and initiates a 500 mL normal saline bolus. While stabilizing, he gathers information: the patient spiked a fever (39.2C) one hour prior. He orders stat labs including CBC, BMP, lactate, and blood cultures. Lactate returns at 4.2 mmol/L. Recognizing this as septic shock, he escalates to his senior resident, who activates the sepsis protocol. The intern documents the event thoroughly, including timeline, interventions, and rationale for escalation. The patient is transferred to the ICU and recovers with appropriate antibiotic therapy and resuscitation.

### Key Learning Points
- Page triage requires rapid assessment of urgency: emergent pages (patient instability) require immediate bedside response within minutes
- Systematic approach to patient deterioration follows ABC assessment, stabilization interventions, diagnostic evaluation, and appropriate escalation
- Recognizing when to escalate to senior residents or attendings is a critical skill that protects patients and demonstrates appropriate self-awareness of limitations

## Case 2: Documentation and Copy-Forward Error

### Case Presentation
A 27-year-old female surgery intern writes a progress note on hospital day 5 for a 72-year-old female post-cholecystectomy patient. Using copy-forward functionality, she copies the previous day's note and updates the subjective section. However, she fails to update the physical examination, which still documents "surgical site with mild erythema, no drainage" from three days prior. On rounds, the attending examines the patient and finds purulent drainage from the incision site. The note's inaccurate examination documentation created a false impression that the surgical site was stable, potentially delaying recognition of a developing surgical site infection. The intern is counseled on documentation best practices: notes must be timely, accurate, and complete. Copy-forward should be used cautiously, with all sections updated to reflect current findings. Physical examination must document what was actually observed, not what was expected or previously documented. The incident is used as a teaching moment for the entire team about documentation integrity.

### Key Learning Points
- Copy-forward functionality creates significant documentation risks including perpetuation of outdated information and inaccurate examination findings
- Documentation serves clinical, legal, educational, and billing purposes, making accuracy and completeness essential professional responsibilities
- Physical examination documentation must reflect current, directly observed findings rather than copied or assumed information

## Case 3: Procedural Competence and Informed Consent

### Case Presentation
A 26-year-old male emergency medicine intern is asked to place a peripheral IV catheter in a 45-year-old female patient presenting with dehydration and vomiting. The nursing staff has attempted twice without success. Before approaching the patient, the intern confirms the indication (IV access for fluid resuscitation), reviews his technique mentally, and gathers all necessary equipment. At bedside, he introduces himself, explains the procedure, discusses risks (pain, bruising, infection, need for additional attempts), benefits (ability to receive IV fluids and medications), and alternatives (oral rehydration if tolerable). The patient provides verbal consent. He performs a timeout, verifying correct patient identity. He applies a tourniquet, identifies a suitable vein in the forearm, prepares the site with alcohol, and successfully cannulates the vein on first attempt using sterile technique. He documents the procedure including indication, consent obtained, technique used, successful placement confirmed by blood return and saline flush, and no immediate complications. The patient receives IV fluids and antiemetics with rapid improvement.

### Key Learning Points
- Procedure preparation includes confirming indication, obtaining informed consent, performing a timeout, and gathering all necessary equipment before patient contact
- Informed consent requires explanation of the procedure, risks, benefits, and alternatives in understandable language
- Procedure documentation must include indication, consent, technique, findings, complications, and any specimens sent to create a complete medical-legal record
