1.

Which of the following is most accurate regarding the administration of vasopressin during cardiac arrest?

A.

Vasopressin is indicated for VF and pulseles sVT prior to the delivery of the first shock
B.

The correct dose of Vasopressin is 40 U administered IV or IO
C.

Vasopressin is recommended instead of epinephrine for the treatment of asystole
D.

Vasopressin can be administered twice during cardiac arrest

Correct Answer
B. The correct dose of Vasopressin is 40 U administered IV or IO

Explanation
The correct answer states that the accurate dose of Vasopressin is 40 U administered intravenously (IV) or intraosseously (IO). This means that during cardiac arrest, when Vasopressin is administered, it should be given at a dosage of 40 U through either the IV or IO route. This information is important for healthcare professionals to ensure the correct administration of Vasopressin during a cardiac arrest situation.

Your patient has been intubated. IV/IO access is not available. Which combination of drugs can be administered by the endotracheal route of administration?

A.

Amiodarone, Lidocaine, Epinephrine
B.

Epinephrine, Vasopressin, Amiodarone
C.

Lidocaine, Epinephrine, Vasopressin
D.

Vasopressin, Amiodarone, Lidocaine

Correct Answer
C. Lidocaine, EpinepHrine, Vasopressin

Explanation
The endotracheal route of administration is not the ideal route for drug administration, as it is associated with poor absorption and unpredictable drug levels. However, in emergency situations where IV/IO access is not available, certain drugs can be administered via the endotracheal tube. Lidocaine, Epinephrine, and Vasopressin are among the drugs that can be given through this route. These drugs are commonly used in cardiac arrest situations to restore and maintain a stable heart rhythm.

Which of the following statements about the use of magnesium in cardiac arrest is most accurate?

A.

Magnesium is indicated for VF/pulseless VT associated with torsades de pointes
B.

Magnesium is indicated for shock-refractory monomorphic VT
C.

Magnesium is contraindicated in VT associated with a normal QT interval
D.

Magnesium is indicated for VF refractory to shock and amiodarone or lidocaine

Correct Answer
A. Magnesium is indicated for VF/pulseless VT associated with torsades de pointes

Explanation
Magnesium is indicated for VF/pulseless VT associated with torsades de pointes. This means that magnesium is most appropriate to use in cases of ventricular fibrillation (VF) or pulseless ventricular tachycardia (VT) when it is associated with a specific type of VT called torsades de pointes. Torsades de pointes is a type of polymorphic VT that is characterized by a prolonged QT interval on an electrocardiogram. Magnesium helps to stabilize the cardiac membrane and can be effective in treating torsades de pointes.

A patient with possible ACS and a bradycardia of 42/min has ongoing chest discomfort. What is the initial dose of atropine?

A.

Atropine 0.5 mg
B.

Atropine 1.0 mg
C.

Atropine 0.1 mg
D.

Atropine 3 mg

Correct Answer
A. Atropine 0.5 mg

Explanation
The initial dose of atropine for a patient with possible ACS and bradycardia is 0.5 mg. Atropine is a medication used to increase heart rate, and in this case, it is necessary to relieve the patient's ongoing chest discomfort. The dose of 0.5 mg is appropriate for initial administration to help increase the heart rate and alleviate symptoms.

5.

A patient is in cardiac arrest. VFib has been refractory to an initial shock. Of the following, which drug and dose should be administered first by IV/IO route?

A.

Atropine 1 mg
B.

Epinephrine 1 mg
C.

Vasopressin 20 U
D.

Sodium bicarbonate 50 mEq

Correct Answer
B. EpinepHrine 1 mg

Explanation
Epinephrine 1 mg should be administered first by IV/IO route in a patient in cardiac arrest with refractory VFib. Epinephrine is a vasopressor and a key medication in the management of cardiac arrest. It helps to increase coronary and cerebral perfusion pressure, improve myocardial and cerebral blood flow, and enhance the chances of successful resuscitation. Atropine is not indicated for VFib, but rather for symptomatic bradycardia. Vasopressin is an alternative to epinephrine, but it is no longer recommended as the first-line drug. Sodium bicarbonate is used for certain specific indications, such as tricyclic antidepressant overdose or severe metabolic acidosis, but it is not the initial treatment for VFib.

You are monitoring this patient after successful resuscitation. You note the above rhythm on the cardiac monitor and document a rhythm strip for the patient's chart. She has no complaints and blood pressure is 110/70 mmHg. Now you would:

A.

Prepare for transcutaneous pacing (place pacing pads, do not pace yet)
B.

Give atropine 0.5 mg IV
C.

Start dopamin 2 to 10 mcg/kg/min and titrate heart rate
D.

Give atropine 1 mg IV
E.

Administer sedation and begin immediate transcutaneous pacing at 80 beats/min

Correct Answer
A. Prepare for transcutaneous pacing (place pacing pads, do not pace yet)

Explanation
Based on the given information, the patient has a rhythm on the cardiac monitor that requires preparation for transcutaneous pacing. This means that the patient's heart rate or rhythm is not adequate and needs to be corrected using external pacing. The other options such as giving atropine or starting dopamin are not appropriate in this case as the patient has no complaints and a normal blood pressure. Administering sedation and immediate transcutaneous pacing at 80 beats/min is also not necessary at this point. Therefore, the correct next step is to prepare for transcutaneous pacing by placing the pacing pads.
