ALS Questions with Correct Answers
for Specific Exam Mail
Stemi may present with T depression in leads V1-3 of a 12-
lead ECG: True or False
Ans: T depression in leads V1-3 of a 12-lead ECG.
Stemi may present as a LBBB, true or false.
Ans: TRUE.
New LBBB is diagnostic of STEMI.
In transcutaneous pacing, electrical capture is what?
Ans: 50-100mA
Electrical capture and generation of a QRS complex
ensures return of a pulse.
Pretest - Stuvia US
,2
Ans: A QRS complex does not guarantee myocardial
contractility. Absence of a pulse in the presence of good
electrical capture constitutes PEA.
Reference:
Chapter 10. How to perform transcutaneous pacing
(p106).
The correct answer is 'False'.
In drowning: Prophylactic antibiotic therapy should be
given routinely. TRUE or FALSO
Ans: False. No evidence of benefit.
You arrive at the bedside 4 min after the cardiac arrest of
a 70 kg woman. An IV line is in place, there is no pulse. The
ECG confirms asystole. Two nurses are performing CPR
competently. You would recommend:
Q: Delivery of a 150 J shock.
TRUE or FALSE
Pretest - Stuvia US
, 3
Ans: False.
The treatment of asystole does not include defibrillation.
Is the PaO2 appropriate here: PaO2 22.6 kPa (FiO2 85%)
normal value >11kpa on air
Ans: NO.
The PaO2 should be numerically about 10 less than the
inspired concentration. In this case this would be > 60 kPa.
Reference:
Chapter 15. PaO2 (p174).
Can 8.4% Sodium bicarbonate lead to exacerbating
intracellular acidosis.
Ans: YES.
Not routinely recommended for metabolic acidosis. Has
several adverse effects, including exacerbating
intracellular acidosis.
Pretest - Stuvia US
