ALS MCQ's EXAM STUDY SET WITH COMPLETE SOLUTIONS 100%
VERIFIED!!!! ALREADY GRADED A+
STEMI - is always accompanied by chest pain? - (ANSWER)False
Elderly. diabetics and patients with renal disease may not have chest pain
STEMI - rarely causes VF - (ANSWER)FALSE
During the acute phase, there is substantial risk of VF.
STEMI - may present with ST-depression in leads V1-3 of a 12-lead ECG. - (ANSWER)TRUE
A posterior STEMI will show ST-depression in leads V1-3.
STEMI - may present with new left bundle branch block (LBBB) on the ECG - (ANSWER)TRUE
New LBBB is diagnostic of STEMI.
When using transcutaneous pacing: - (ANSWER)
When using transcutaneous pacing:
electrical capture typically occurs with a current of 5-10 amps. - (ANSWER)FALSE
Capture typically occurs with a current of 50-100 mA (i.e. 100 times less).
When using transcutaneous pacing:
may be unsuccessful in a patient with hyperkalaemia - (ANSWER)TRUE

VERIFIED!!!! ALREADY GRADED A+
When using transcutaneous pacing:
movement artefact may inhibit the pacemaker. - (ANSWER)TRUE
If there is lot of movement artefact on the ECG, this may be misinterpreted by the pacemaker and inhibit
it.
When using transcutaneous pacing:
electrical capture and generation of a QRS complex ensures return of pulse - (ANSWER)FALSE
A QRS complex does not guarantee myocardial contractility. Absence of pulse in the presence of good
electrical capture constitutes PEA
ECG:
continuous monitoring via self-adhesive pads is preferable to using the ECG electrodes - (ANSWER)FALSE
Adhesive defibrillator pads should be used in an emergency to assess the cardiac rhythm
ECG:
if adhesive electrodes are used for 3-lead monitoring, they should be applied over bone rather than
muscle. - (ANSWER)FALSE
bone> muscle to minimise interference

ECG:
normal PR interval is >0.2s - (ANSWER)FALSE
The normal PR interval is between 0.12 and 0.20 s (3-5 small squares
ECG:
The normal QRS complex interval is <0.12 s (< 3 small squares). - (ANSWER)TRUE
IN DROWNING:
there is immediate entry of water into the victim's lungs - (ANSWER)FALSE
There is initially laryngospasm and breath holding preventing entry if water unto the victim's lung.
IN DROWNING:
resuscitation should be considered even it the patient has been submersed in water for 5 min -
(ANSWER)TRUE
Submersion durations of less than 10 min are associated with very high chance of a good outcome, and
submersion durations of more than 25 min are associated with a low chance of good outcome.
IN DROWNING:
following submersion, respiratory arrest usually precedes cardiac arrest - (ANSWER)TRUE
Cardiac arrest is usually a secondary event following a period of hypoxia
