2 A B C D Answer

With regards to the use of HCO 3 in shock, which is FALSE? HCO 3 shifts O2 dissociation curve to the right to allow increased O2 delivery from Hb at lower tissue pO2 HCO 3 improves the myocardial depression associated with shock HCO 3 counteracts the insensitivity to endogenous catecholamines attributed to acidosis HCO 3 worsens intracellular acidosis-

3 A B C D Answer

Which of the following is NOT a criterion for SIRS? Temperature < 36 C HR > 90 RR < 6 or PaCO2 < 23 mmHg WCC with > 10% immature bandso

4 A B C D Answer

In early shock, which of the following is FALSE? SBP may rise as a result of increased cardiac contractility DBP may rise secondary to arteriolar VC A high mortality rate secondary to impaired LVF is seen in a persistent shock index >1 Polyuria excludes shock secondary to sepsis

5 A B C D Answer

The first compensatory response to shock is which of the following? An increased CO A fall in O2 content of blood A rise in respiratory rate A fall in the mixed venous O2 saturation

6 A B C D

With regards to lactic acidosis, which is FALSE? An elevated lactate is a marker of impaired O2 delivery or utilization A raised lactate correlates with short term prognosis of critically ill patients in ED In septic shock and in post resuscitation from cardiac arrest, one would expect a raised lactate with a reduced mixed venous O2 saturation A raised lactate in the setting of a metabolic acidosis, with a raised anion gap and normal osmolar gap and no ketosis is a characteristic feature of toluene poisoning

Answer

7 A B C D Answer

Which of the following is NOT a metabolic feature of shock? Prerenal azotemia Hyponatraemia Hyperglycaemia Hypoglycaemia

Which of the following best describes the following definition? Sepsis associated with organ dysfunction, hypoperfusion, or hypotension. Hypoperfusion and perfusion abnormalities may include, but are not limited to lactic acidosis, oliguria, or an acute alteration in mental status. Septic shock Sepsis Severe sepsis SIRS

A B C D Answer

9 A B C D Answer

A man who has lost 1700mL of blood in a trauma situation will Require only crystalloid fluid replacement Have a pulse rate of 90 Have lost 30-40% of blood volume Have a normal pulse pressure

10 A B C D Answer

The most common cause of sudden cardiac death is A Cardiomyopathy B WPW C Coronary artery disease D Drugs

11 A B C D Answer

The following is true of Defibrillation Most defibrillators now manufactured use a monophasic waveform The monophasic waveform requires less energy for successful defibrillation than the biphasic type Biphasic waveforms allow smaller more portable defibrillation devices. Monophasic defibrillators should no longer be used

12 A B C D Answer

Regarding resuscitation guidelines which of the following is FALSE? Majority of survivors of sudden cardiac arrest have VF as a primary rhythm Emphasis is focused also on pre-arrest period and post-resuscitation management Fist pacing is of no value in unstable bradyarrhythmias when a pacemaker is not immediately available Rescue breathing provides a FiO2 0.15-0.18

13 A B C D Answer

Suggested indications for resuscitative thoracotomy in patients with traumatic cardiac arrest include all of the following EXCEPT Penetrating cardiac trauma and arrival in ED after /= 70% Transfusion of RBC to haematocrit >/= 40%

23 A B C D Answer

With regards to paediatric resuscitation, which of the following is INCORRECT? ETT size = Age/4 +4 Weight in Kg = (Age x 2) + 8 ETT insertion distance at lips = (Age/2) + 12 Adrenaline dose 0.1ml / kg of 1:1000 solution

24 A B C D Answer

With respect to intraosseous needles which is FALSE The distal femur is one appropriate site for insertion An IO needle should be attempted in a paediatric resuscitation if IV access has not been achieved within 90 seconds Compartment syndrome is a recognised complication Their use is contraindicated in neonates due to the high rate of growth plate injury

27 A B C D Answer

Features increasing the safety of Endotracheal tubes include all of the following EXCEPT: Bevelled atraumatic tip Translucency of the tube Murphys eye Small volume , high pressure distal cuff

28 A B C D Answer

Factors making paediatric intubation more difficult include all the following EXCEPT: Upper airways are more compliant Large tongue Larynx is more cephalad Epiglottis is larger and floppy

29 A B C D Answer

Which of the following is NOT a link in the chain of survival? Early Defibrillation Early CPR Early Drug Delivery Post resuscitation care

30 A

With regards to cardiac arrest in the third trimester of pregnancy, which of the following statements is TRUE if there is no return of spontaneous maternal circulation within 10 minutes of cardiac arrest and CPR commencement, a perimortem caesarean section should be performed. the patient should be tilted by placing a roll under the patient's left hip and flank. adrenaline is contraindicated as it causes uteroplacental vasoconstriction. avoid the femoral vein when obtaining IV access.

B C D Answer

31 A B C D Answer

Which of the following about central venous access is INCORRECT? There is a greater infection rate with femoral vein CVCs The risk of carotid puncture is greater with the central approach to the internal jugular as opposed to the posterior or anterior approach Femoral vein approach is relatively contraindicated in pregnancy The rate of infusion is dependant on the radius of the line and the length

33 A B C D Answer

With regard to central venous lines Pneumothorax is not a complication of internal jugular insertion Subclavian lines have the highest incidence of arterial puncture Using a supraclavicular approach the needle is directed at the contralateral nipple Femoral lines have the lowest incidence of venous thrombosis

34 A B C D Answer

Which is the most reliable method of confirming endotracheal tube placement? Equal bilateral breath sounds End Tidal CO2 capnography Misting of the tube with expiration Chest X-ray

35 A B C D Answer

With regards to parenteral fluid compositions which is CORRECT Hartmann's contains Na 131 K 5 Cl 111 5% Dextrose contains 50g/LDextrose osmol 300 4% Dextrose 0.18% saline contains Dextrose 40g/L Cl 30 Na 40 mmol 0.9% saline contains Na 150 mmol/L Cl 150 pH 6

According to the ILCOR 2010 Resuscitation Guidelines, once ROSC is achieved and the oxygen saturation of arterial blood can be monitored reliably, inspired oxygen is titrated to achieve a SaO2 of: >95% 90-95% 94-98% >93%

A B C D Answer

37 A B C D Answer

In regards to resuscitation of a 10Kg child, which of the following is FALSE: ETT size 4 would be appropriate The dose of adrenaline is 0.1mLs/kg of 1:10 000 solution The rate of external cardiac compressions is 120/min 5mL/kg 10% dextrose is used to treat hypoglycaemia

39 A B C D Answer

Which of the following is FALSE regarding adult cardiac arrest? 50% of out of hospital cardiac arrests have an initial rhythm of VF/VT Atropine is not recommended in treatment of asystole Continuous waveform CO2 monitoring is useful for detecting ROSC There is less evidence supporting the use of hypothermia post-arrest for comatose survivors with an initially non-shockable rhythm.
