WorksheetsCME CARDIO WEEK 4 : ACLS
Total questions: 16
Worksheet time: 5mins
You are attending to a 56 year-old diabetic woman complaining of chest discomfort. She is pale and
diaphoretic, complaining of lightheadedness. Her BP is 80/60 mm Hg. The cardiac monitor documents the
rhythm above. She is receiving supplemental oxygen and an IV has been established.
What medication you would administer to this patient?
Dopamine 2 to 10 ụg/kg per minute
IV morphine sulfate 4 mg
IV atropine 1 mg
IV atropine 0.5 mg
Which among this is FALSE regarding atropine ?
Causes paradoxical bradycardia
Crosses the blood brain barrier
A non - competitive acetylcholine receptor antagonist
Is hallucinogenic
Lidocaine can be used as an alternative to amiodarone in cardiac arrest from VF/pVT. Which of the following statement regarding lidocaine is FALSE ?
Lidocaine blocks permeability of the neuronal membrane to sodium ions
If no IV/IO access available , the dose for ET administration is 2-4 mg/kg
The initial dose is 0.5 to 0.75mg/kg IV/IO over 5 -10 minute intervals
Lidocaine classified as class 1b agent
The correct dose of epinephrine given in the bradycardia algorithm is:
1-5 mcg/min infusion
2-8 mcg/min infusion
2-10 mcg/min infusion
5-10 mcg/min infusion
A 30 year old lady presented to ED complaining of palpitation. Her HR was 178 bpm and is hemodynamically stable. Vagal maneuvers were unsuccessful.You proceeded to give IV Adenosine. Which regarding adverse effects of Adenosine is NOT true ?
Bronchospasm
Thrombocytosis
Asystole
Facial flushing
If the initial shock terminates VF but it recurs again later in the resuscitation ,
Deliver subsequent shocks at the maximum energy dose
Deliver subsequent shocks at the previously successful energy level
Do not deliver any subsequent shocks and continue CPR
Begin cardioversion
Epinephrine is used during resuscitation:
Because it causes vasoconstriction
To stop allergic reactions causing heart failure
As a pain reliever for the victim
Because it is an antiarrhythmic
You give amiodarone 300 mg (first dose ) and finish the cycle of CPR for a patient.Upon rhythm check , you see the patient has converted to normal sinus rhythm and has a pulse.As you begin the post arrest care , patient has a short run of VT. In light of continued arrhythmia , you start an amiodarone drip for maintenance therapy.What is maximum cumulative dose for amiodarone in a 24 hr period?
2.4 grams
1.5 grams
2.2 grams
5.0 grams
AV nodal blocking agents should be avoided in:
Patients with a regular SVT
Patients with a regular VT
AF with Pre Excitation
All of the above
What is NOT a precaution to Transcutaneous Pacing (TCP)?
TCP is contraindicated in severe hypothermia and is not recommended for asystole
Conscious patients require analgesia for discomfort unless delay for sedation will cause/contribute to deterioration
Avoid AV nodal blocking agents
Do not assess the carotid pulse to confirm mechanical capture
All the following statements are TRUE regarding the arrythmia shown above EXCEPT ;
Prolonged repolarisation period gives rise to delayed after-depolarisation
.TdP is initiated when a PVC occurs during the preceeding T wave, known as ‘R on T’ phenomenon
Treatment includes IV Magnesium Sulfate 1-2g
Hypokalemia could be a cause
Torsades de Pointes can be caused by the following drugs EXCEPT ;
Amiodarone
Procainamide
Lithium
Pseudoephedrine
What are the 2 most common causes of Pulseless Electrical Activity ?
Hypothermia and hypoxia
Hypovolemia and hypoxia
Hypovolemia and hyperkalemia
Hypoxia and hyperkalemia
End points for the administration of procainamide infusion for stable wide QRS tachycardia include:
Hypotension
50 - 100 mg/min until arrhythmia suppresed
Maximum dose of 7 mg/kg is reached
Increase in heart rate by 30 points
Which of the following drugs can be administered via endotracheal route ?
Amiodarone, epinephrine
Epinephrine, amiodarone
Lidocaine, epinephrine
Procainamide , lidocaine
What is the correct energy dose for unstable atrial fibrillation when delivering monophasic synchronized shocks?
50 to 100 J
120 - 200 J
Treat with high-energy shocks (defibrillation doses)
200 J
