Correct Answer is D
Explanation
The correct answer is choice D. Requires nasogastric suction.

Nasogastric suction removes gastric secretions that contain potassium, leading to a loss of potassium from the body.
This can cause hypokalemia, which is a low level of potassium in the blood.
Choice A is wrong because Addison’s disease causes hyperkalemia, which is a high level of potassium in the blood.
Choice B is wrong because tissue damage can release potassium from the cells into the blood, causing hyperkalemia.
Choice C is wrong because uric acid level is not related to potassium level.
Uric acid is a waste product of purine metabolism that can cause gout or kidney stones if elevated.
