Chapter 29: Coordinating Care for Patients with
Cardiac Dysrhthmia RE
3 - ANS-A patient's heart rate is 48 beats per minute. Which structure is most likely generating
this heart rate?
1 - ANS-The nurse is concerned that a patient is at risk for pulseless electrical activity. What
information from the assessment did the nurse use to make this clinical decision?
3 - ANS-A patient asks why cardiac leads are being placed on the chest. What should the nurse
respond to this patient?
1) "It shows where the heart vessels are blocked."
2) "It is used to evaluate the effectiveness of dietary changes."
3) "It provides a graphic picture of the heart's electrical activity."
4)"It determines which medications are needed to improve heart function."
4 - ANS-When analyzing a patient's electrocardiogram, the nurse notes that the P wave is
normal. What criteria did the nurse use to make this decision?
1) Pointed and skinny in width
2) Small and rounded in lead II
3) Upright and rounded in lead II
4)Length 0.10 seconds and height 2.5 mm
4 - ANS-A patient is being evaluated for a blockage in the cardiac ventricles. On which part of
the electrocardiogram should the nurse focus as evidence of this blockage?
1) T wave
2) U wave
3) PR interval
, 4) QRS interval
3 - ANS-The nurse is observed marching out the rhythm on a patient's cardiac monitor tracing.
What is this nurse assessing?
1) Rate
2) Polarity
3) Regularity
4) Amplitude
1 - ANS-A patient with shortness of breath has a heart rhythm of 46 beats per minute. Which
medication should the nurse anticipate being prescribed for this patient?
3 - ANS-A patient with atrial fibrillation has a heart rate of 90 beats per minute. Which
manifestation should the nurse expect to assess in this patient?
4 - ANS-A patient with atrial fibrillation is being considered for cardioversion. Which diagnostic
test should the nurse anticipate being prescribed prior to this procedure being completed?
1) Chest x-ray
2) CT scan of the chest
3) 12-lead electrocardiogram
4) Transesophageal echocardiogram (TEE)
2 - ANS-A patient is experiencing supraventricular tachycardia. What should be done before
determining this patient's treatment?
1) Assess for thyroid disease
2) Identify the underlying rhythm
3) Evaluate serum electrolyte values
4)Study lifestyle and behavioral habits
3 - ANS-A patient is admitted for treatment for a low junctional rhythm. Where should the nurse
expect to assess the P wave on this patient's electrocardiogram?
