The healthcare provider prescribes and IV solution of regular insulin (Humulin-R) 100 units in 250 ml of 0.45% saline to infuse at 12 units/hour. The nurse should program the infusion pump to deliver how many ml/hour?
The Correct Answer is ["30"]
First, we need to find the concentration of insulin in the IV solution, which is the ratio of insulin units to saline volume. To do this, we use the given information that the IV solution contains 100 units in 250 ml. So, we divide 100 by 250 and get 0.4 units/ml.
Next, we need to calculate the infusion rate in ml/hour for the ordered dose of 12 units/hour. To do this, we use the ratio of insulin units to saline volume, which is 0.4 units/ml. So, we set up a proportion as follows:
0.4/1=12/x
To solve for x, we cross-multiply and get 0.4 x = 12. Then, we divide both sides by 0.4 and get x = 30. So, the infusion rate is 30 ml/hour.
Therefore, the nurse should program the infusion pump to deliver 30 ml/hour..

Correct Answer is C
Explanation
Choice A: Assessing pupillary response to light hourly is not related to dopamine administration. Dopamine does not affect the pupils or the cranial nerves that control them.
Choice B: Initiating seizure precautions is not necessary for a client receiving dopamine. Dopamine does not lower the seizure threshold or cause convulsions.
Choice C: Measuring urinary output every hour is an important intervention for a client receiving dopamine. Dopamine increases blood pressure and cardiac output, which improves renal perfusion and urine production. Urinary output is an indicator of the effectiveness of dopamine therapy and renal function.
Choice D: Monitoring serum potassium frequently is not directly related to dopamine administration. Dopamine does not affect potassium levels or cause hyperkalemia or hypokalemia. However, potassium levels may be affected by other factors such as fluid balance, renal function, and medications.
Correct Answer is D
Explanation
Choice A: Increasing oxygen to 6 liters/minute is not an intervention that the nurse should implement, as this can worsen bronchospasm and hypoxia by reducing the hypoxic drive and causing carbon dioxide retention. This is a contraindicated choice.
Choice B: Calling for an Ambu resuscitation bag is not an intervention that the nurse should implement, as this is not indicated for a client who is conscious and breathing spontaneously. This is an overreaction choice.
Choice C: Instructing the client to lie back in bed is not an intervention that the nurse should implement, as this can increase respiratory distress and compromise airway clearance by reducing lung expansion and increasing abdominal pressure. This is another contraindicated choice.
Choice D: Administering a nebulizer treatment is an intervention that the nurse should implement, as this can deliver bronchodilators and anti-inflammatory agents directly to the airways and improve ventilation and oxygenation for this client. Therefore, this is the correct choice.
