Denning [Date] [Course title]
, A patient who is otherwise healthy is experiencing premature atrial contractions (PACs). The patient asks
what could be causing the PACs. Which is the best response by the nurse?
A. "Your low-protein diet."
B. "Your coffee and cigarette use."
C. "Your family history of diabetes."
D. "Your sedentary lifestyle and high-fat diet." - Answer: B. "Your coffee and cigarette use."
In a normal heart, a PAC can result from the use of caffeine or tobacco.
Which statement describes a patient who has an ECG reading with a ventricular rate of 120 and loss of
the atrial kick?
A. The patient experiences a decrease in cardiac output because of ineffective atrial contractions.
B. The patient experiences no symptoms associated with a ventricular rate of 120 and loss of atrial kick.
C. The patient experiences loss of consciousness and requires CPR because the heart is not perfusing the
body.
D. The patient experiences an increase in cardiac output because the increase ventricular rate supports
the loss of atrial kick. - Answer: A. The patient experiences a decrease in cardiac output because of
ineffective atrial contractions.
The high ventricular rates (greater than 100 beats/minute) and loss of the atrial "kick" (atrial contraction
reflected by a sinus P wave) that are associated with atrial flutter decrease cardiac output.
A patient is diagnosed with atrial fibrillation. Which ECG findings does the nurse expect?
A. Atrial rate 80 bpm/regular ventricular rhythm
B. Atrial rate 400 bpm/consistent ventricular rate
C. Atrial rate 200 bpm/ventricular rate irregular and variable
D. Atrial rate of 580 bpm/variable and irregular ventricular rate - Answer: D. Atrial rate of 580
bpm/variable and irregular ventricular rate
During atrial fibrillation, the atrial rate may be as high as 350 to 600 beats/minute. Ventricular rate
varies and the rhythm is usually irregular.
The nurse is caring for a patient with shortness of breath, dizziness, and chest pressure. The nurse notes
a thready, irregular pulse, and an ECG that indicates atrial fibrillation. Which action would the nurse take
first?
