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: Mark an outline of the 'olive-shaped' mass in the right epigastric area. This is not a priority action, as it does not address the immediate needs of the infant. The 'olive-shaped' mass is a sign of pyloric stenosis, but it does not affect the infant's hydration or nutrition.

Choice B: Instruct parents regarding care of the incisional area. This is an important action, but not a priority before surgery. The parents need to know how to care for the incisional area after surgery, but this can be done later.

Choice C: Monitor amount of intake and infant's response to feedings. This is a relevant action, but not a priority before surgery. The infant with pyloric stenosis may have vomiting, dehydration, and electrolyte imbalance due to gastric outlet obstruction. Monitoring intake and output can help assess the severity of these problems, but it does not correct them.

Choice D: Initiate a continuous infusion of IV fluids per prescription. This is the priority action before surgery, as it can prevent or treat dehydration and electrolyte imbalance in the infant. IV fluids can also help maintain blood volume and perfusion during surgery.

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.
