A nurse is assisting in the care of a client whose cardiac monitor suddenly displays ventricular tachycardia. Which of the following is the priority nursing action?

Perform immediate defibrillation.

Provide pulmonary ventilation.

Determine palpable pulse.

Begin chest compressions.

Answer and Explanation

The Correct Answer is C

A. Perform immediate defibrillation: This is necessary for ventricular tachycardia with a pulse if it is unstable, but first, assess the client’s condition.
B. Provide pulmonary ventilation: This may be required depending on the client's breathing status but is secondary to assessing the pulse.
C. Determine palpable pulse: This is the priority action. Determining whether the client has a pulse helps guide the next steps—if the client has a pulse but is symptomatic, treatment will differ from if the client is pulseless.
D. Begin chest compressions: This is done if the client is pulseless. If there is a pulse, other interventions are needed first.

A. Warm the insulin vial to dissolve any crystals that develop: Insulin should not be warmed as this can alter its efficacy. If crystals are present, the vial should be gently rolled, not heated.

C. Store opened insulin vials at room temperature for up to 4 weeks: Opened insulin vials can be stored at room temperature for up to 4 weeks, which helps maintain its stability and usability.
D. Plan to eat a snack 6 hr after insulin administration: The timing of snacks should be aligned with insulin administration based on the type and dosage, not a fixed interval of 6 hours.

Correct Answer is ["1.5"]

Explanation

• Desired dose: 15,000 units
• Available concentration: 10,000 units/mL
• To find the volume to administer, we can use the formula:
• Volume to administer (mL) = Desired dose (units) / Concentration (units/mL)
• Volume to administer = 15,000 units / 10,000 units/mL = 1.5 mL
