Dysrhythmias Misc nclex questions with correctanswers
The nurse administers amiodarone (Cordarone) to a client with
ventricular tachycardia. Which monitoring by the nurse is necessary
with this drug? Select all that apply.
a. Respiratory rate
b. QT interval
c. Heart rate and rhythm
d. Magnesium level
e. Urine output Correct Answer-Answer: QT interval; Heart rate and
rhythm; Magnesium level
Rationale: Amiodarone causes prolongation of the QT interval, which
can precipitate dysrhythmia. Antidysrhythmic medications cause
changes in cardiac rhythm and rate; therefore monitoring of heart rate
and rhythm is needed.Electrolyte depletion, specifically potassium and
magnesium, may predispose to further dysrhythmia. Although it is
always important to monitor vital signs and urine output, these
assessments are not specific to amiodarone.
The nurse is caring for a client with acute coronary syndrome (ACS) and
atrial fibrillation who has a new prescription for metoprolol (Lopressor).
Which monitoring is essential when administering the medication?
a. ST segment
b. Heart rate
c. Troponin
,d. Myoglobin Correct Answer-Answer: Heart rate
Rationale: The effects of metoprolol are to decrease heart rate, blood
pressure, and myocardial oxygen demand. ST segment elevation is
consistent with MI; it does not address monitoring of metoprolol.
Elevation in troponin is consistent with a diagnosis of MI but does not
address needed monitoring for metoprolol. Elevation in myoglobin is
consistent with myocardial injury in ACS but does not address needed
monitoring related to metoprolol.
The nurse is caring for a client with atrial fibrillation. In addition to an
antidysrhythmic, what medication does the nurse plan to administer?
a. Heparin
b. Atropine
c. Dobutamine
d. Magnesium sulfate Correct Answer-Answer: Heparin
Rationale: Clients with atrial fibrillation are prone to blood pooling in
the atrium, clotting, then embolizing. Heparin is used to prevent
thrombus development in the atrium and the consequence of
embolization (i.e., stroke).
The nurse is caring for a client on a telemetry unit with a regular heart
rhythm and rate of 60; a P wave precedes each QRS complex, and the
PR interval is 0.24 second. Additional vital signs are as follows: blood
pressure 118/68, respiratory rate 16, and temperature 98.8° F. The
, following medications are available on the medication record. What
action should the nurse take?
a. Administer atropine.
b. Administer digoxin.
c. Administer clonidine.
d. Continue to monitor. Correct Answer-Answer: Continue to monitor.
Rationale: The client is displaying sinus rhythm with first-degree
atrioventicular heart block; this is usually asymptomatic and does not
require treatment. Atropine is used in emergency treatment of
symptomatic bradycardia. This client has normal vital signs. Digoxin is
used in the treatment of atrial fibrillation, which is, by definition, an
irregular rhythm. Clonidine is used in the treatment of hypertension; a
side effect is bradycardia.
You are the charge nurse on the telemetry unit and are responsible for
making client assignments. Which client would be appropriate to assign
to the float RN from the medical-surgical unit?
a. The 64-year-old admitted for weakness who has a first-degree heart
block with a heart rate of 58 beats/min
b. The 71-year-old admitted for heart failure who is short of breath and
has a heart rate of 120 to 130 beats/min
c. The 88-year-old admitted with an elevated troponin level who is
hypotensive with a heart rate of 96 beats/min
d. The 92-year-old admitted with chest pain who has premature
ventricular complexes and a heart rate of 102 beats/min Correct Answer-
