ANSWERS GRADED A+
The nurse is caring for a patient on a telemetry unit with a regular heart rhythm and
rate of 60 beats/min; 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. All of these medications are available
on the medication record. What action does the nurse take?
1
Administer digoxin
2
Administer atropine
3
Continue to monitor
4
Administer clonidine - ANSWER_3
The patient is displaying normal sinus rhythm. Atropine is used in emergency
treatment of symptomatic bradycardia. This patient 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.
When caring for a patient with heart disease, which action may lead to serious
bradydysrhythmias?
1
Oropharyngeal suctioning
2
Insertion of a Foley catheter
3
Hip flexion greater than 90 degrees

4
Walking on a treadmill at a moderate pace - ANSWER_1
Anything that causes the patient to perform the Valsalva maneuver (e.g., bear
down, gag, or vomit) leads to vagal stimulation. Unintended vagal stimulation can
result in serious bradydysrhythmias and should be avoided. Oropharyngeal
suctioning causes the patient to gag and possibly vomit. Insertion of a Foley
catheter, hip flexion, and moderate walking on a treadmill do not induce the
Valsalva maneuver.
A patient with atrial fibrillation with rapid ventricular response has received
medication to slow the ventricular rate. The pulse is now 88 beats/min. For which
additional therapy does the nurse plan?
1
Anticoagulation
2
Synchronized cardioversion
3
Electrophysiology studies (EPS)
4
Radiofrequency ablation therapy - ANSWER_1
Because of the risk for thromboembolism caused by atrial fibrillation,
anticoagulation is necessary. The patient has stabilized; cardioversion is not needed
at this time. EPS is indicated for recurring, symptomatic dysrhythmia. Ablation
therapy is ordered for recurring and symptomatic atrial fibrillation.
A patient is admitted to the intensive care unit with an acute pulmonary embolism.
What dysrhythmia would most likely contribute to this condition?

ANSWERS GRADED A+
1
Atrial fibrillation
2
Sinus bradycardia
3
Ventricular tachycardia
4
Premature atrial contractions - ANSWER_1
Because the atria are not fully contracting in atrial fibrillation, there is stagnation of
blood flow resulting in formation of thrombi in the atria. A thrombus can be
dislodged from the right atrium and travel to the lung, causing a pulmonary
embolus. There is not a risk of thrombus formation with sinus bradycardia,
premature atrial contractions, or ventricular tachycardia.Test-Taking Tip: Look for
answers that focus on the patient or are directed toward feelings.
Which precaution should the nurse follow when providing cardiopulmonary
resuscitation (CPR) and advanced cardiac life support (ACLS) to a patient?
1
Protective Isolation
2
Standard Precautions
3
Surgical asepsis with defibrillator
4
Respiratory isolation during intubation - ANSWER_2
, NUR 398 DYSRHYTHMIAS SOLVED EXAM (ACTUAL
LATEST 2025) WITH DETAILED AND VERIFIED
ANSWERS GRADED A+
Standard Precautions and personal protective equipment must be used when there
is risk of contact with blood and body fluids. Protective isolation is designed to
protect the patient from pathogens in the environment. Surgical asepsis involves
ridding an item of all pathogens, such as in the operating room, with sterilization
procedures. A defibrillator is a "clean," not sterile, item. Respiratory isolation is
used to prevent transmission of organisms by droplets, such as chickenpox or
meningitis. The nurse may choose to use protective eyewear or a face shield during
intubation or suctioning of the airway to protect from spraying blood and body
fluids.
In caring for a patient following an acute myocardial infarction, what is the greatest
priority when planning care?
Provide a low-fat, low-sodium diet
2
Pad the oxygen tubing behind the ears
3
Wear TED hose and sequential compression devices while in bed
4
Monitor for increased frequency of premature ventricular contractions -
ANSWER_4
Increasing frequency of premature ventricular contractions following an acute
myocardial infarction can lead to life-threatening ventricular dysrhythmias.
Prophylaxis of venous thromboembolism, cardiac diet, and prevention of skin
breakdown are important, but the greatest priority is the risk of life-threatening
dysrhythmias.Test-Taking Tip: Avoid selecting answers that state hospital rules or
regulations as a reason or rationale for action.
