The healthcare provider prescribes dopamine 2 mcg/kg/min intravenously (IV) for client who weighs 60 kg. The IV bag contains dopamine 200 mg in dextrose 5% in water (DW) 250 mL. The nurse should program the infusion pump to deliver how many mL/hour? (Enter numerical value only.)
The Correct Answer is ["9"]
Here are the steps you can follow to calculate the infusion pump flow rate:
Step 1: Calculate the prescribed dose in mcg/min
- Dose per weight: 2 mcg/kg/min * 60 kg = 120 mcg/min
Step 2: Convert the concentration in the IV bag to mcg/mL
- Convert mg to mcg: 200 mg * 1000 mcg/mg = 200,000 mcg
- Concentration: 200,000 mcg / 250 mL = 800 mcg/mL
Step 3: Calculate the flow rate in mL/min
- Flow rate: 120 mcg/min / 800 mcg/mL = 0.15 mL/min
Step 4: Convert the flow rate to mL/hour
- Hour conversion: 0.15 mL/min * 60 min/hour = 9 mL/hour
Therefore, the nurse should program the infusion pump to deliver 9 mL/hour.

Correct Answer is A
Explanation
Assessing the client's level of consciousness involves observing their responsiveness, orientation, and ability to follow commands. If the client is unresponsive or exhibits any signs of altered consciousness, the nurse should immediately activate the emergency response system and begin resuscitative measures, such as administering oxygen and initiating cardiopulmonary resuscitation (CPR) if necessary.
Once the client's level of consciousness is established and the emergency response system has been activated if necessary, the nurse can proceed to assess the depth of the slashes, estimate the amount of blood loss, and find the object used to cause the injuries. These assessments will provide important information about the extent and severity of the client's injuries, which will guide subsequent interventions.
Correct Answer is D
Explanation
The correct answer is choice D: Begin chest compressions at 100/minute.
Choice A rationale:
Observing for swelling at the fracture site is not immediately relevant in this emergency situation. The priority is to address the lack of pulse and respiration.
Choice B rationale:
Analyzing the cardiac rhythm in another lead is unnecessary when the patient has no pulse and is not breathing. Immediate life-saving measures are required.
Choice C rationale:
Obtaining a 12-lead electrocardiogram is not the priority in this scenario. The patient needs immediate resuscitation efforts.
Choice D rationale:
Beginning chest compressions at 100/minute is the correct intervention. The absence of a carotid pulse and spontaneous respirations indicates cardiac arrest, and chest compressions are essential to maintain circulation and oxygenation until further help arrives.
