Advanced – Dysrhythmias Practice
Exam Questions 2025 |100% Correct|
-Antidysrhythmic Drugs (slow ventricular conduction or to convert the AF to NSR) - calcium channel
blockers, beta-blockers, digoxin
-Anticoagulants (benefits of preventing stroke v. risk of bleeding)
-heparin, warfarin, lovenox (prevent strokes associated with AF)
-Percutaneous radio frequency catheter ablation *Ans*✨What does treatment look like for atrial
fibrillation?
-anxiety, pain, stress, fever, anemia, hypoxemia, hyperthyroidism.
-drugs such as epinephrine, atropine, caffeine, alcohol, nicotine, cocaine, aminophylline, and thyroid
medications may increase HR.
-a compensatory response to decreased CO or BP as occurs in dehydration, hypovolemic shock,
myocardial infarction, infection, and heart failure. *Ans*✨What are possible causes for sinus
tachycardia?
-assess vital signs at least every 4 hours and as needed.
-monitor for cardiac dysrhythmias
-evaluate and document the patient's response to dysrhythmias.
-encourage patient to notify the RN when chest pain occurs.
-assess chest pain (ex: location, intensity, duration, radiation, and precipitating and alleviating factors)
-provide antidysrhthmic therapy according to unit policy (ex: anti-dysrhythmic medication,
cardioversion, or defibrillation) as appropriate.
-monitor and document patient's response to antidysrhythmic medications or interventions.
-monitor appropriate lab values (ex: cardiac enzymes, electrolyte levels)
-monitor patient's activity tolerance and schedule exercise/rest periods to avoid fatigue
-observe for respiratory difficulty (ex: shortness of breath, rapid breathing, labored respirations)
-promote stress reduction
-offer spiritual support to the patient and/or family, as appropriate. *Ans*✨What does care for a
patient with dysrhythmias look like?
, -chest discomfort, pressure, or pain which may radiate to the jaw, the back ,or the arm.
-restlessness, anxiety, nervousness, confusion
-dizziness, syncope
-palpitations (tachy)
-change in pulse strength, rate, and rhythm
-pulse deficit
-shortness of breath, dyspnea
-tachypnea
-pulmonary crackles
-orthopnea
-S3 or S4 heart sounds
-jugular venous distention
-weakness, fatigue
-pale, cool, skin; diaphoresis
-N/V
-decreased urine output
-delayed capillary refill
-hypotension *Ans*✨What are key features of sustained tachydysrhythmias and bradydysrhythmias?
1 *Ans*✨Class ___________ antidysrhythmics are membrane-stabilizing agents used to decrease
automaticity. Three subclassifications which include type 1A drugs which moderately slow conduction
and prolong depolarization, prolonging the QT interval. Type 1B shorten depolarization. Type 1C slow
conduction and widen the QRS complex.
1A *Ans*✨Type _________ anti-dysrhythmic drugs moderately slow conduction and prolong
depolarization, prolonging the QT interval. Used to treat supraventricular and ventricular premature
beats and tachydysrhythmia. Ex: procainamide hydrochloride (pronestyl)
