Dopamine 5 mcg/kg/minute IV is prescribed for a client who weighs 132 pounds. The pharmacy dispenses a 500 mL IV solution of 0.9% normal saline with dopamine 1600 mg. The nurse should program the infusion pump to deliver how many ml/hour? (Enter numeric value only. If rounding is required, round to the nearest tenth)
The Correct Answer is ["5.6"]
Convert pounds to kg 1kg= 2.2 pounds 132pounds= 132/2.2=60kg
Desired dose per minute= 5 mcg/kg= 560=300mcg/min Desired dose per hour= 300mcg60mins= 18000mcg Available dose= 1600mg/500ml
1mg=1000mcg
Available dose = 1600000mcg/500ml Infusion rate:
1600000mcg=500ml 18000mcg=18000500/1600000
= 5.625 mL/hour
Rounded to the nearest tenth: 5.6 ml/hour

Correct Answer is D
Explanation
A. Keep the bed in the lowest position and initiate seizure and fall precautions: While seizure and fall precautions may be necessary for safety, the client's symptoms, including right-sided weakness and sluggish speech, are indicative of a potential stroke rather than a seizure. Immediate intervention to assess for and treat possible stroke is critical.
B. Place an indwelling urinary catheter and measure strict intake and output: Although urinary management may be necessary, it is not the priority in this situation. The client's symptoms suggest a neurological issue that requires urgent assessment and intervention.
C. Maintain elevated positioning of the dependent joints on affected side: Elevating the dependent joints is a strategy used in managing conditions like stroke to prevent complications such as edema, but it does not address the immediate need for stroke assessment and intervention.
D. Start two large bore IV catheters and review inclusion criteria for IV fibrinolytic therapy: Correct! The client's presentation with right-sided weakness and sluggish speech suggests a possible ischemic stroke. Starting IV access and reviewing inclusion criteria for IV fibrinolytic therapy (tPA is crucial for timely intervention to restore blood flow and minimize neurological damage.
