During a pre-flight assessment of a trauma patient, you note a receding mandible and a thick neck. Which component of the LEMON mnemonic are you primarily addressing, and why is this critical in the transport environment?
Show answer →This represents the L (Look Externally) in the LEMON mnemonic. External features like a receding mandible (micrognathia) or a bull neck are highly predictive of difficult laryngoscopy. In transport, these physical markers are vital because they provide an immediate visual cue to prepare secondary equipment (e.g., video laryngoscopy, bougie) before takeoff, where space and movement are restricted. BCEN emphasizes early recognition of these red flags to prevent can't intubate, can't oxygenate (CICO) scenarios in the air.
While assessing Neck Mobility (LEMON) in a trauma patient in a C-collar, you recognize the N is compromised. What is the GOLD STANDARD for managing the airway while maintaining spinal precautions in transport?
Show answer →Manual In-Line Stabilization (MILS) is the gold standard. The front of the C-collar is opened, and an assistant holds the head steady to prevent extension/flexion while the nurse performs intubation. BCEN highlights that N (Neck mobility) is the most frequently encountered difficult factor in trauma. Use of Video Laryngoscopy (VL) is highly recommended here as it requires less neck extension than direct laryngoscopy (DL) to visualize the cords.
During transport of a patient with scattered splash burns across multiple body areas, which assessment method is most appropriate for calculating TBSA, and what represents 1%?
Show answer →The Palmar Method is best for scattered, small, or irregular burns. The patient's entire hand (palm and fingers) represents approximately 1% of their TBSA. BCEN Tip: Ensure you use the patient's hand size, not the clinician's. This method is often used for burns <15% TBSA or for subtracting unburned areas in large TBSA injuries.
According to current ABA guidelines used in CTRN practice, what is the preferred initial crystalloid for burn resuscitation, and why are boluses generally avoided?
Show answer →Preferred Fluid: Lactated Ringers (LR) or balanced salt solutions. LR is preferred over Normal Saline to avoid iatrogenic hyperchloremic metabolic acidosis. Boluses are avoided because they increase hydrostatic pressure, worsening burn shock edema and potentially converting partial-thickness burns to full-thickness. Fluids should be titrated strictly to UOP.
A 3-month-old is being transported for fussiness. Assessment reveals a small, healing frenulum tear. Why is this finding critical for the transport nurse to document and report?
Show answer →A frenulum tear in a non-ambulatory infant is a classic sentinel injury—a minor injury that often precedes severe or fatal physical abuse. Other sentinel injuries include oral trauma, unexplained bruising, or subconjunctival hemorrhages. Rationale: These require a full skeletal survey and social work intervention. Exam Tip: BCEN focuses on the nurse's role as a mandatory reporter. Even minor skin or oral findings in infants are high-priority for NAT screening and must be communicated during handoff.
