Which medication below should not be used for the treatment of sinus bradycardia in a patient
with a transplanted heart?
a. Isoproterenol
b. Atropine
c. Epinephrine
d. Glucagon - CORRECT ANSWER-b. Atropine
,A 20-year-old has a mandatory electrocardiogram (ECG) before participating on a college soccer
team and is found to have sinus bradycardia, rate 52. Blood pressure (BP) is 114/54, and the
student denies any health problems. What action by the nurse is most appropriate?
a. Allow the student to participate on the soccer team.
b. Refer the student to a cardiologist for further diagnostic testing.
c. Tell the student to stop playing immediately if any dyspnea occurs.
d. Obtain more detailed information about the students family health history. - CORRECT
ANSWER-a. Allow the student to participate on the soccer team.
In an aerobically trained individual, sinus bradycardia is normal. The students normal BP and
negative health history indicate that there is no need for a cardiology referral or for more
detailed information about the family's health history. Dyspnea during an aerobic activity such
as soccer is normal.
A patient develops sinus bradycardia at a rate of 32 beats/minute, has a blood pressure (BP) of
80/42 mmHg, and is complaining of feeling faint. Which actions should the nurse take next ?
a. Recheck the heart rhythm and BP in 5 minutes.
b. Have the patient perform the Valsalva maneuver.
c. Give the scheduled dose of diltiazem (Cardizem).
d. Apply the transcutaneous pacemaker (TCP) pad. - CORRECT ANSWER-d. Apply the
transcutaneous pacemaker (TCP) pad.
,Normal PR Interval - CORRECT ANSWER-0.12-0.20 seconds
Normal QRS Duration - CORRECT ANSWER-0.06 to 0.10 seconds
Sinus bradycardia originates in what part of the electrical conduction system?
a. AV node
b. SA node
c. Bundle Branches
d. Bundle of His - CORRECT ANSWER-b. SA node
You're analyzing a patient's ECG reading. What should be found in the rhythm for it to be
considered Sinus Bradycardia (select all that apply):
a. One p wave present in front of every QRS complex
b. Atrial rate 60 and ventricular rate of 60
c. Regular atrial and ventricular rate
d. Atrial rate 40 and ventricular rate of 40
e. Regular atrial rate and irregular ventricular rate
f. PR interval 0.14 seconds
g. PR interval 0.36 seconds
, h. QRS interval 0.08 seconds
i. QRS interval 0.16 seconds - CORRECT ANSWER-a. One p wave present in front of
every QRS complex
c. Regular atrial and ventricular rate
d. Atrial rate 40 and ventricular rate of 40
f. PR interval 0.14 seconds
h. QRS interval 0.08 seconds
You obtain an ECG on a patient and the rhythm is sinus bradycardia with a rate of 52 bpm. Your
NEXT nursing action is to?
a. Prepare to administer Atropine IV push
b. Set-up for transcutaneous pacing
c. Assess the patient
d. Call a rapid response - CORRECT ANSWER-c. Assess the patient
Assess the patient. When discovering sinus bradycardia, the nurse should determine if the
patient is having symptoms. Not all cases of this rhythm require medical treatment.
Your patient is experiencing extreme fatigue, hypotension, palpations, and shortness of breath.
You obtain an ECG and discover a rhythm of sinus bradycardia with a rate of 40 bpm. What
finding below could be causing this condition?
