VERIFIED ANSWERS | GRADED A+
(2026/2027 UPDATED)
1. Epinephrine 1 mg or vasopressin 40 units IV or IO. - Correct Answer -A patient is
in cardiac arrest. High-quality chest compressions are being given. The patient is
intubated and an IV has been started. The rhythm is asystole. Which is the first
drug/dose to administer?
1. Epinephrine 1 mg or vasopressin 40 units IV or IO.
2. Atropine 1 mg IV or IO.
3. Atropine 0.5 mg IV or IO.
4. Epinephrine 3 mg via endotracheal route.
5. Dopamine 2 to 20 mcg/kg per minute IV or IO.
4. Repeat adenosine 12 mg IV . - Correct Answer -A 45-year-old woman with a
history of palpitations develops light-headedness and palpitations. She has
received adenosine 6 mg IV for the rhythm shown above without conversion of
the rhythm. She is now extremely apprehensive. Blood pressure is 108/70 mm Hg.
What is the next appropriate intervention?
1. Repeat adenosine 3 mg IV.
2. Perform immediate unsynchronized cardioversion.
3. Sedate and perform synchronized cardioversion.
4. Repeat adenosine 12 mg IV .
,5. Perform vagal maneuvers and repeat adenosine 6 mg IV.
1. Sublingual nitroglycerin 0.4 mg. - Correct Answer -A patient in the emergency
department develops recurrent chest discomfort (8/10) suspicious for ischemia.
His monitored rhythm becomes irregular as seen above. Oxygen is being
administered by nasal cannula at 4 L/min, and an IV line is in place. Blood pressure
is 160/96 mm Hg. There are no allergies or contraindications to any medication.
You would first order:
1. Sublingual nitroglycerin 0.4 mg.
2. Morphine sulfate 2 to 4 mg IV.
3. Lidocaine 1 mg/kg IV and infusion 2 mg/min.
4. Amiodarone 150 mg IV.
5. IV nitroglycerin initiated at 10 mcg/min and titrated to patient response.
5. Prepare to give epinephrine 1 mg IV. - Correct Answer -Following initiation of
CPR and 1 shock for VF, this rhythm is present on the next rhythm check. A second
shock is given and chest compressions are resumed immediately. An IV is in place
and no drugs have been given. Bag-mask ventilations are producing visible chest
rise. What is your next order?
1. Administer 3 sequential (stacked) shocks at 360 J (monophasic defibrillator).
2. Prepare to give amiodarone 300 mg IV.
3. Administer 3 sequential (stacked) shocks at 200 J (biphasic defibrillator).
4. Perform endotracheal intubation; administer 100% oxygen.
5. Prepare to give epinephrine 1 mg IV.
, 4. Atropine 0.5 mg IV . - Correct Answer -You arrive on the scene to find a 56-year-
old diabetic woman with dizziness. She is pale and diaphoretic. Her blood
pressure is 80/60 mm Hg. The cardiac monitor documents the rhythm below. She
is receiving oxygen at 4 L/min by nasal cannula and an IV has been established.
Your next order is:
1. Dopamine at 2 to 10 mcg/kg per minute.
2. Sublingual nitroglycerin 0.4 mg.
3. Morphine sulfate 4 mg IV.
4. Atropine 0.5 mg IV .
5. Atropine 1 mg IV.
2. Begin CPR, starting with high-quality chest compressions. - Correct Answer -A
patient becomes unresponsive. You are uncertain if a faint pulse is present with
the rhythm
below. What is your next action?
1. Order transcutaneous pacing.
2. Begin CPR, starting with high-quality chest compressions.
3. Start an IV and give epinephrine 1 mg IV.
4. Consider causes of pulseless electrical activity.
5. Start an IV and give atropine 1 mg.
