EKG NCLEX Questions with Correct
Solutions 2026
A 38-year-old female is brought to the Emergency Department with complaints of her "heart
beating out of her chest". She is diaphoretic, tachypneic and her BP is 70/40. The cardiac
monitor shows supraventricular tachycardia. Valsalva maneuvers and three doses of Adenosine
have not been successful. The nurse should immediately:
a.) prepare the patient for synchronized cardioversion.
b.) give Epinephrine 1 mg IV and repeat in 3 minutes.
c.) give Adenosine 6 mg IV per protocol.
d.) perform unilateral carotid massage. - <CORRECT ANSWER >>a.) prepare the patient for
synchronized cardioversion.
Prior to discharge from the Emergency Department, the nurse prints a rhythm strip on a patient
and notices that the P wave cannot be detected and the QRS complex is 0.24 seconds. This is a
change in the patient's condition. What is the best action for the nurse to take?
a.) Measure the PR interval.
b.) Prepare the patient for discharge.
c.) Notify the physician of this abnormal strip.
d.) Continue to monitor for abnormalities. - <CORRECT ANSWER >>c.) Notify the physician of
this abnormal strip.
Rationale:
c.) is correct because notifying the physician of the abnormal rhythm would be the most
appropriate response. The patient has experienced a rhythm change and requires further
treatment.
, a.) is not correct for measuring the PR would not be possible as there is no P wave present.
Since the QRS interval and other parameters given are abnormal, discharging the patient would
not be appropriate at this point.
b.) is not correct as discharging the patient is not appropriate or safe practice.
d.) is not correct because continuing to monitor the patient without any other actions would be
inappropriate as the patient has experienced a change in condition.

Heparin 500 units subcutaneously. Which of the following interventions should now be
