✔✔What is the ideal method to update an i-STAT device without internet connectivity? -
✔✔The i-STAT can be updated using a second i-STAT with current software.
✔✔T/F: When running the i-STAT external simulator, the electronic simulator will fail if
high relative humidity interferes with the measurements. - ✔✔TRUE

ambient temperature differs by more than __________ °C ( __________°F), allow the
simulator and analyzer to stand in the same place for 30 minutes before inserting the
simulator into the analyzer. - ✔✔3, 5
✔✔Liquid controls used in a cartridge that measures oxygen concentration must stand
at room temperature for a minimum of __________ hours before use; controls for other
analytes only need to equilibrate at room temperature for __________ minutes. - ✔✔4,
30
✔✔How frequently are CLEW software updates on the i-STAT device mandated? -
✔✔Twice (2x) Per Year
✔✔Section 14: Burn Wound Management in Prolonged Field Care - ✔✔-
✔✔A provider of prolonged field care must first and foremost be an expert in

✔✔Burns covering greater than __________ of the Total Body Surface Area (TBSA), or
those with smoke inhalation injury (and airway or breathing problems), are life
threatening. - ✔✔20%
✔✔T/F: Hypothermia risk is high in burn patients. Anticipate that all burn casualties will
become hypothermic and take immediate measures to prevent it by covering patient.
Aggressively rewarm if temperature falls below 36°C (96.8 °F) - ✔✔TRUE
✔✔All patients with burns covering greater than __________ Total Body Surface Area
(TBSA) should be intubated because total-body swelling will tend to obstruct the airway.

providing prolonged field care for a burn patient? - ✔✔Cricothyroidotomy, Ketamine,
Ambu Bag with Positive End-Expiratory Pressure (PEEP) Valve

__________ could indicate clogging of endotracheal tube or poor ventilation from
another cause (e.g., bronchospasm, tight eschar across chest). - ✔✔end-tidal CO2,
end-tidal CO2
✔✔T/F: For large wounds, calculate the size of the wound by using the patient's hand
size (including fingers) to represent a 1% TBSA. - ✔✔FALSE. Use the Rule of Nines
✔✔Sunburns are an example of __________ degree burns. - ✔✔1st
✔✔Over the first 24-48 hours post burn, __________ is lost into the burned and
unburned tissues, causing hypovolemic shock (when burn size is > 20%). - ✔✔plasma
✔✔T/F: Plain water is ineffective for shock resuscitation and can cause hyponatremia. -
✔✔TRUE
✔✔__________ is the main indicator of resuscitation adequacy in burn shock. -
✔✔Urine Output (UO)
✔✔For prolonged care of burn patients, a(n) __________ infusion may provide more
consistent analgesia and help conserve supplies of analgesic medications. -
✔✔ketamine
✔✔When providing wound care for a burn patient, you can use __________ nylon
dressing as an alternative to topical antimicrobial cream. - ✔✔silver
✔✔T/F: When performing an escharotomy incision on a burn patient, you must not carry
the incision across any of the involved joints. - ✔✔FALSE. It is important to ALWAYS
carry the incisions across any involved joints.
✔✔__________ and Exercise are included in the "best", "better", and "minimum" care
recommendations when treating a patient with an extremity burn. - ✔✔Elevate
✔✔Section 15: Frostbite & Immersion Foot Care - ✔✔-
✔✔The ultimate mechanism of cold injury involves these combination of factors... -
✔✔1. Direct Cold Injury to the Cells
2. Direct Intracellular & Intercellular Ice Formation
3. Ischemia from Thrombosis of the Vasculature
4. Reperfusion Injury
