Critical Nursing Arrhythmias Part 2

By:Mohamed Mamdouh

Sinus bradycardia originates in what part of the electrical conduction system?

You're analyzing a patient's ECG reading. What should be found in the rhythm for it to be considered Sinus Bradycardia (select all that apply):

You obtain an ECG on a patient and the rhythm is sinus bradycardia with a rate of 52 bpm. Your NEXT nursing action is to?

Your patient is experiencing extreme fatigue, hypotension, palpations, and shortness of breath. You obtain an ECG and discover a rhythm of sinus bradycardia with a rate of 40 bpm. What finding below could be causing this condition?

Which of the following is NOT a treatment for symptomatic sinus bradycardia?

A patient is experiencing sinus bradycardia with a rate of 34 bpm and blood pressure of 78/42. The patient reports symptoms of chest pain, has cool and clammy skin, dyspnea, and feels like they may faint. The nurse prepares to administer Atropine per a standing physician's order for the patient's symptomatic bradycardia. How will the nurse administer this medication?

Atropine was ineffective for treating the bradycardia. The patient is still symptomatic with a rate 35 bpm. What other options could be considered for the patient? Select all that apply:

True or False: In a First-Degree Heart Block, the atrial rhythm is regular and the QRS complex will measure less than 0.12 seconds.

Your patient is found to have a First-Degree Heart Block after obtaining an ECG. The patient is asymptomatic. The nurse prepares to? Select all that apply:

What medication below could cause a First-Degree Heart Block?

A hallmark finding in a First-Degree Heart Block is?

Which statement below best describes why a First-Degree Heart Block occurs?

True or False: A hallmark finding in a Second-Degree type I (Mobitz I or Wenckebach) heart block is that the PR interval will remain constant throughout the rhythm but there will be a dropped QRS complex after a p wave.

In Second-Degree type I (Mobitz I or Wenckebach) heart block why is the ventricular rate slower than the atrial rate?

Your patient reports they do not feel well and feels very weak. You assess the patient’s vital signs. The patient’s blood pressure is 78/52 and heart rate is irregular and weak. The patient appears clammy and pale. You note a Second-Degree type I heart block on the ECG. What steps should the nurse take? Select all that apply:

What are potential causes of a Second-Degree Type I (Mobitz I or Wenckebach) Heart Block? Select all that apply:

Which of the following is NOT a finding in a Second-Degree Type II heart block (Mobitz II) ECG reading?

TRUE or FALSE: A Second-Degree Type II heart block (Mobitz II) is the most serious type of heart block among all the types of AV heart blocks.

Your patient has a Second-Degree Type II (Mobitz II) heart block. What information found in the patient’s health history is NOT associated with causing this type of rhythm?

TRUE or FALSE: A Third-Degree Heart Block is unlikely to cause symptoms in a patient and usually requires no treatment.

Which option below best describes the findings a nurse would find in a Third-Degree Heart Block (complete heart block)?

Your patient is experiencing a blood pressure of 70/42, weak pulse, chest pain, and is pale. The patient is confused and anxious. An ECG is obtained and a Third-Degree Heart Block is noted. What treatment should the nurse be prepping for? Select all that apply:

Select below all the causes of a Third-Degree Heart block:
