[i] Comments on the answers will be found with the correct answer.
This quiz will repeat any incorrect questions until all questions are answered correctly
[q] 1. Which is false about AEDs ?
[c] a. Early defibrillation is the most important factor in surviving cardiac arrest
[c*] b. AEDs will shock automatically if VT or VF is detected
[f] c. AED only advises shock and charges, manual pressing of delivery must still be done
[c] d. AEDs are designed to advise shock only if tachycardias are of a rate >180 beats/min in VT, VF and SVT
[c] e. AEDs do not have monitor screens to visualize rhythm
[q] 2. Which is True of traction leg splints?
[c] a. Traction leg splints can be used if even if a pelvic fracture is suspected
[c] b. Traction leg splints should not be used for tibial shaft fractures even if they are angulated or displaced
[c*] c. Fractures near the knee are contraindicated for traction splints as they may cause damage to popliteal neurovascular structures
[f] contraindicated for hip fractures or dislocations, can be used in displaced and angulated tib #
[c] d. Hip dislocations are not contraindicated for traction splints
[q] 3. Regarding helicopter air transportation of patients
[c] a. All pneumothoraces need a chest tube prior to transport regardless of size of pneumothorax
[c] b. Endotracheal tubes inflated with gas should target pressures of 30-40 cm water.
[c] c. Patients who have had a traumatic cardiac arrest should be given highest priority for helicopter transport to a trauma centre.
[c*] d. To minimize aspiration risk gastric tubes should be inserted on an unconscious patient.
[q] 4. Regarding Neonatal and infant emergency long distance transportation
[c*] a. Aim glucose level >5 by infusing 10% dextrose at rate of 80ml/kg/day
[f] preductal is right hand, Fi 1.0 paO2 <100 with signs of cyanotic heart disease indicates a right to left shunt and needs PGE1 to reopen ductus arteriosus [c] b. Chest xrays are not necessary to confirm ETT placement prior to transport if reassuring signs of a successful intubation are present
[c] c. Infants with right to left shunt and pulmonary hypertension can be diagnosed with pulse oximetry difference of >10% between readings on the left hand (preductal) vs the foot (postductal)
[c] d. Hypoxic infants on Fi 0.5 with Pao2 of < 100 mmHg should be given prostaglandin E1 infusion between 0.05 mcg/kg/min to 0.1 mcg/kg/min [q] 5. Regarding long distance athletic events (marathon, triathlon) which of the following is false [c] a. Risk factors for symptomatic hyponatraemia <125 are exercise > 4 hours, female sex, low BMI
[c] b. Severe hyponatraemia with associated confusion, altered conscious state and seizures should have a goal of replacing Na by 2mmol/L/hour until symptoms resolve
[c*] c. Hyponatraemia secondary to dehydration can be prevented by drinking >500ml/h of water
[f] hyponatraemia due to free water overload can be prevented by limiting drinking to <500 ml/h [c] d. Caution should be exercised with use of 3% saline as correcting Na too quickly can cause central pontine myelinolysis [/qwiz]
