A 6-week-old infant with pyloric stenosis is scheduled for a pyloromyotomy. Which pre-operative nursing action has the highest priority?

Choice A: Instructing the client to increase his intake of oral fluids until the skin flushing is relieved is not an appropriate action for the nurse, as this does not address the cause of the flushing, which is vasodilation due to tadalafil. This is a distractor choice.

Choice B: Advising the client to place one nitroglycerin tablet under his tongue as a precaution is a dangerous action for the nurse, as this can cause severe hypotension and cardiovascular collapse due to the interaction between tadalafil and nitroglycerin. This is a contraindicated choice.

Choice C: Telling the client to have someone bring him to an emergency department immediately is an unnecessary action for the nurse, as there is no evidence of any serious adverse reaction or complication from tadalafil. This is an overreaction choice.

Choice D: Reassuring the client that skin flushing is a common side effect of the medication is an appropriate action for the nurse, as this can calm the client and educate him about the expected effects of tadalafil. Therefore, this is the correct choice.

Choice B reason: Forcing oral fluids and providing frequent small meals are not the most important interventions for a client with alcohol withdrawal delirium. Although hydration and nutrition are important to prevent dehydration and electrolyte imbalance, they are not the priority in this case. The client may have difficulty swallowing, vomiting, or aspiration due to altered mental status.

Choice C reason: Confronting the client's denial of substance abuse is not an appropriate intervention for a client with alcohol withdrawal delirium. The client may not be able to comprehend or respond rationally to such confrontation due to impaired cognition and perception. The nurse should avoid arguing or challenging the client's beliefs and focus on providing safety and comfort.

Choice D reason: Encouraging attendance and group participation is not a feasible intervention for a client with alcohol withdrawal delirium. The client may not be able to participate in any social or educational activities due to severe withdrawal symptoms and delusions. The nurse should limit visitors and stimuli and provide one-to-one supervision and reassurance.
