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?

Choice A is correct because a quiet, non-stimulating environment can help reduce the agitation, confusion, and hallucinations that are common in alcohol withdrawal delirium. The nurse should also provide reassurance, orientation, and safety measures to the client.

Choice B is incorrect because forcing oral fluids and providing frequent small meals are not the most important interventions for a client with alcohol withdrawal delirium. The client may have difficulty swallowing, nausea, vomiting, or diarrhea that can interfere with oral intake. The nurse should monitor the client's hydration and nutrition status and provide intravenous fluids or supplements as needed.

Choice C is incorrect because confronting the client's denial of substance abuse is not the most important intervention for a client with alcohol withdrawal delirium. The client may not be able to comprehend or accept the reality of their situation due to their altered mental state. The nurse should avoid arguing or challenging the client and focus on providing supportive care.

Choice D is incorrect because encouraging attendance and group participation are not the most important interventions for a client with alcohol withdrawal delirium. The client may not be able to participate in group activities due to their severe withdrawal symptoms and may need individualized care. The nurse should facilitate referrals to appropriate resources for substance abuse treatment when the client is stable and ready.

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..
