encourage intake of orange juice or a banana with each meal

obtain a physician's order for cardiac monitoring

Answer and Explanation

Correct Answer : C,E

Choice A rationale: Diluting potassium elixir in juice is not a priority intervention for a critically elevated potassium level. Immediate actions are needed.

Choice B rationale: Monitoring intake and output is important, but it is not the highest priority when the potassium level is critically elevated.

Choice C rationale: Assessing the client for muscle weakness and flaccid paralysis is a high priority because hyperkalemia can lead to serious cardiac and neuromuscular complications.

Choice D rationale: Encouraging intake of orange juice or a banana may be appropriate for managing mild hypokalemia, but it is not the priority for a client with critically elevated potassium.

Choice E rationale: Obtaining a physician's order for cardiac monitoring is crucial, as hyperkalemia can lead to life-threatening cardiac dysrhythmias.
