COMPLETE QUESTIONS WITH 100%
VERIFIED ANSWERS
\.The nurse is caring for a patient who has had an ECG. The nurse notes that leads
I, II, and III differ from one another on the cardiac rhythm strip. How should the
nurse best respond?
A) Recognize that the view of the electrical current changes in relation to the lead
placement.
B) Recognize that the electrophysiological conduction of the heart differs with
lead placement.
C) Inform the technician that the ECG equipment has malfunctioned.
D) Inform the physician that the patient is experiencing a new onset of
dysrhythmia. - ANSWERS✔-Ans: A
Feedback:
Each lead offers a different reference point to view the electrical activity of the
heart. The lead displays the configuration of electrical activity of the heart.
,Differences between leads are not necessarily attributable to equipment
malfunction or dysrhythmias.
\.The nurse is analyzing a rhythm strip. What component of the ECG corresponds
to the resting state of the patient's heart?
A) P wave
B) T wave
C) U wave
D) QRS complex - ANSWERS✔-Ans: B
Feedback:
The T wave specifically represents ventricular muscle depolarization, also referred
to as the resting state. Ventricular muscle depolarization does not result in the P
wave, U wave, or QRS complex.
\.The nurse is writing a plan of care for a patient with a cardiac dysrhythmia. What
would be the most appropriate goal for the patient?
A) Maintain a resting heart rate below 70 bpm.
,B) Maintain adequate control of chest pain.
C) Maintain adequate cardiac output.
D) Maintain normal cardiac structure. - ANSWERS✔-Ans: C
Feedback:
For patient safety, the most appropriate goal is to maintain cardiac output to
prevent worsening complications as a result of decreased cardiac output. A resting
rate of less than 70 bpm is not appropriate for every patient. Chest pain is more
closely associated with acute coronary syndrome than with dysrhythmias. Nursing
actions cannot normally influence the physical structure of the heart.
\.The nurse is caring for an adult patient who has gone into ventricular fibrillation.
When assisting with defibrillating the patient, what must the nurse do?
A) Maintain firm contact between paddles and patient skin.
B) Apply a layer of water as a conducting agent.
C) Call "all clear" once before discharging the defibrillator.
D) Ensure the defibrillator is in the sync mode. - ANSWERS✔-Ans: A
, Feedback:
When defibrillating an adult patient, the nurse should maintain good contact
between the paddles and the patient's skin to prevent arcing, apply an
appropriate conducting agent (not water) between the skin and the paddles, and
ensure the defibrillator is in the nonsync mode. "Clear" should be called three
times before discharging the paddles.
\.A patient who is a candidate for an implantable cardioverter defibrillator (ICD)
asks the nurse about the purpose of this device. What would be the nurse's best
response?
A) "To detect and treat dysrhythmias such as ventricular fibrillation and ventricular
tachycardia"
B) "To detect and treat bradycardia, which is an excessively slow heart rate"
C) "To detect and treat atrial fibrillation, in which your heart beats too quickly and
inefficiently"
D) "To shock your heart if you have a heart attack at home" - ANSWERS✔-Ans: A
