A nurse is reviewing abnormal laboratory values for four clients who have schizophrenia and take clozapine.
For which of the following clients should the nurse withhold the medication and notify the provider immediately to have clozapine therapy discontinued?
A client who has a BUN of 22 mg/dL.
A client who has a serum potassium of 3.3 mEq/L.
A client who has a hematocrit of 55%.
A client who has a WBC of 2,900 cells/mm².
The Correct Answer is D
Choice A rationale:
A BUN of 22 mg/dL is slightly elevated but not a contraindication for clozapine.
Choice B rationale:
A serum potassium of 3.3 mEq/L is slightly low but not a contraindication for clozapine.
Choice C rationale:
A hematocrit of 55% is high but not a contraindication for clozapine.
Choice D rationale:
A WBC of 2,900 cells/mm² is low and can indicate agranulocytosis, a potentially life-threatening condition. Clozapine should be discontinued.

Correct Answer is {"A":{"answers":"B"},"B":{"answers":"C"},"C":{"answers":"C"},"D":{"answers":"A"}}
Explanation
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 A
Explanation
Choice A rationale:
Assigning a staff member to stay with the client at all times is the priority action when a client declines to make a safety contract. This is because the immediate safety of the client is the primary concern in such situations.
Choice B rationale:
Locking the doors to the unit and securing windows so they cannot be opened might be considered a safety measure, but it is not the priority. The focus should be on direct supervision to ensure safety.
Choice C rationale:
Removing any objects from the client’s environment that could be used for self-harm is important, but it is not the priority. The immediate safety of the client through constant supervision is the priority.
Choice D rationale:
Providing the client with plastic eating utensils for meals is a safety measure, but it is not the priority. The immediate safety of the client through constant supervision is the priority.
