ventricular tachycardia
Answer: C. Anemia can contribute to sinus tachycardia.
The nurse sees the following rhythm on the monitor. Which of the following lab values

c) Hgb 9
d) Magnesium 2.1
Answer: A. Following defibrillation, CPR is immediately initiated if a perfusable rhythm is
not initiated. The client may need to be shocked again, but chest compressions must
begin first.
ventricular fibrillation
The patient who has recently been experiencing runs of ventricular tachycardia
suddenly loses consciousness. The patient is defibrillated, and the rate returns as the
following. What should the nurse do first?
A) Begin compressions
B) Shock the client again immediately
, C) Prepare for intubation
D) Administer adenosine
Answer: B. Antiarrhythmic medications are prescribed with the use of an ICD in order to

medications would the nurse expect to see in the MAR for this patient?
A) Warfarin

Answer: B. Atrial flutter places the client at high risk for development of clot formation in

be performed at this time. Before cardioversion can occur in a patient, anticoagulant
therapy should be begun at least 48 hours beforehand if possible.
The patient with a history of hypertension and diabetes has the following rhythm strip.
The patient's vitals are as follows: BP 145/89, HR 90, SpO2 95%, RR 19. Which of the

a) Prepare the client for cardioversion STAT
b) Begin administering anticoagulants
c) Grab the crash cart for administration of adenosine
d) Teach the client about possibility of pacemaker installation
