A student nurse is explaining premature atrial contraction (PAC) to his class
and would be correct by saying which of the following about where a PAC is
produced
A. SA node
B. AV node
C. By an irritable cell in ventricle
D. By an irritable cell in atria - correct answer SA node
The impulse is initiated by an irritated cell in the atria
AV node
The impulse is initiated by an irritated cell in the atria
By an irritable cell in ventricle
The impulse is initiated by an irritated cell in the atria
By an irritable cell in atria
The impulse is initiated by an irritated cell in the atria.
A client with pericarditis is being evaluated for dizziness and shortness of
breath. His heart rate on the monitor demonstrates supraventricular
tachycardia. Which of the following interventions is most appropriate in this
situation
A. Have the client perform the Valsalva maneuver
B. Start CPR at a rate of 100 compressions per minute
C. Administer a vasopressor medication, such as epinephrine
D. Give the patient 8 oz. of water to drink - correct answer Have the client
perform the Valsalva maneuver
,Supraventricular tachycardia (SVT) is a type of cardiac arrhythmia in which
the heart beats rapidly. The rhythm originates in the atria of the heart and can
cause a heart rate of up to 300 bpm. The client becomes lightheaded and
dizzy because his heart is not effectively pumping blood due to the rapid rate.
The initial method of management is to ask the client to "bear down", known
as the Valsalva maneuver. The maneuver can also be achieved by having the
client close their mouth, pinch their nose and blow against closed airways.
This causes increased intrathoracic pressure, blood pressure and heart rate
shifts, and may convert the arrhythmia back into a normal rhythm.
Start CPR at a rate of 100 compressions per minute
Compressions are indicated when there is no pulse, and when the client is
unconscious. This is not the case in the above scenario.
Administer a vasopressor medication, such as epinephrine
Epinephrine would cause an increased heart rate, which is the opposite effect
of what is needed in this situation.
Give the patient 8 oz. of water to drink
Having the client consume liquids during SVT would not contribute to
correcting their arrhythmia.
A client presents to the emergency department saying, "My heart is racing out
of my chest!" The EKG shows that the client is in supraventricular tachycardia
(SVT). Which of the following medications would the nurse anticipate giving
this client
A. Alprazolam
B. Alendronate
C. Amiodarone
D. Amitryptiline - correct answer Alprazolam
Alprazolam (Xanax) is a benzodiazepine that is used to relieve anxiety and
calm the nerves, but it will not slow the heart rate in the client with SVT.
Alendronate
This drug is a biphosphonate that is used for clients who have osteoporosis.
, Amiodarone
Amiodarone (Pacerone) is an antiarrhythmic medication used to slow the
heart down for clients with supraventricular tachycardias and atrial fibrillation.
Amitryptiline
This drug is a tricyclic antidepressant used for clients with depression.
The nurse is caring for a client who is suffering from frequent premature
ventricular contractions. Which of the following is true of this condition Select
all that apply.
A. It arises from one or more atrial ectopic foci
B. It may decrease the efficiency of the heart's pumping action
C. The client may experience an irregular heartbeat
D. The client is usually hypertensive
E. It is commonly caused by a myocardial infarction - correct answer It
arises from one or more atrial ectopic foci
A PVC originates in ventricular foci, not atrial foci.
It may decrease the efficiency of the heart's pumping action
The client with frequent premature ventricular contractions may have a
decrease in the efficiency of the heart's pumping action, as it can reduce
cardiac output.
The client may experience an irregular heartbeat
A PVC is an irregular heartbeat, and the client will be able to feel the
irregularity.
The client is usually hypertensive
A client with PVC's is usually normotensive.
It is commonly caused by a myocardial infarction
It is commonly caused by myocardial infarction, and the client is usually
normotensive. The condition arises from one or more ventricular ectopic foci.
The nurse should notify the provider if the PVCs increase in frequency, are
