A nursing student is looking at a telemetry screen with multiple rhythms. The unit is a step-down cardiac unit with delicate patients. Patients on Census. The unit has:
1. 84-year-old male with AFib, diaphoretic, and complaining of fatigue.
2. 45-year-old female with SVT not responding to adenosine.
3. 78-year-old female with bradycardia who was given atropine and epinephrine, yet unresolved.
4. 80-year-old male in pulseless Ventricular fibrillation being coded and transferred to Intensive Care Unit.
5. 69-year-old female who arrived at the unit symptomatic and currently being coded is pulseless with Ventricular Tachycardia.
The nurse on the step-down unit explains to the nursing student the electricity to be used for each dysrhythmia. Select the correct electricity to be used to manage the dysrhythmias listed:
Transcutaneous Pacing, Defibrillation, or Synchronized cardioversion?
Dysrhythmias:
1. Ventricular fibrillation.
2. PVC-run ventricular tachycardia with a pulse.
3. Atrial Flutter.
4. Bradycardia.
Ventricular fibrillation
PVC-run ventricular tachycardia with a pulse.
Atrial Flutter.
Bradycardia
The Correct Answer is {"A":{"answers":"B"},"B":{"answers":"C"},"C":{"answers":"C"},"D":{"answers":"A"}}
Ventricular fibrillation: The correct electricity is Defibrillation. Ventricular fibrillation is a life-threatening condition that requires immediate medical attention. Defibrillation is the process of delivering an electric shock to the heart to stop the fibrillation and allow the heart’s normal rhythm to resume4.
PVC-run ventricular tachycardia with a pulse: The correct electricity is Synchronized Cardioversion. This is used when the patient is hemodynamically stable. It involves the delivery of a therapeutic dose of electrical current to the heart at a specific moment in the cardiac cycle5.
Atrial Flutter: The correct electricity is Synchronized Cardioversion. Atrial flutter is a type of abnormal heart rhythm, or arrhythmia. It can be treated with synchronized cardioversion, in which a controlled electric shock is delivered to the heart to restore normal rhythm5.
Bradycardia: The correct electricity is Transcutaneous Pacing. This is a temporary means of pacing a patient’s heart during a medical emergency. It should be undertaken by healthcare providers who are trained in the procedure5.
So, the correct answer is Defibrillation for Ventricular fibrillation, Synchronized Cardioversion for PVC-run ventricular tachycardia with a pulse and Atrial Flutter, and Transcutaneous Pacing for Bradycardia, after analyzing all choices.

Correct Answer is D
Explanation
Choice A rationale:
Diarrhea is not a specific reason to stop lithium. However, severe diarrhea can affect lithium levels and should be reported to a healthcare provider.
Choice B rationale:
Lithium does not need to be taken on an empty stomach. It can be taken with or without food.
Choice C rationale:
A low-salt diet is not recommended while on lithium. In fact, a consistent, normal sodium intake is important because low sodium levels can cause lithium levels to become too high.
Choice D rationale:
Regular blood tests are necessary when taking lithium to ensure therapeutic levels and prevent toxicity. Weekly blood tests may be required during the first month of treatment.
Correct Answer is A
Explanation
Choice A rationale:
The client is displaying manifestations of lithium toxicity, which includes ataxia and blurred vision. Therefore, the nurse should withhold the medication.
Choice B rationale:
Administering the next dose as prescribed could potentially exacerbate the client’s symptoms and increase the risk of further toxicity.
Choice C rationale:
Propranolol is not typically used in the management of lithium toxicity.
Choice D rationale:
Levothyroxine is used to treat hypothyroidism and is not relevant in this context.
