Potassium replacement is done to prevent hypokalemia, which is common in DKA.

Choice A rationale:

Potassium replacement is indeed necessary in DKA treatment.

This choice is incorrect because DKA often leads to hypokalemia (low potassium levels).

Potassium is an essential electrolyte for various bodily functions, including proper heart function, and low levels can be life-threatening.

Therefore, potassium replacement is a vital part of DKA treatment.

Choice B rationale:

The primary reason for potassium replacement in DKA is to prevent hypokalemia.

As mentioned earlier, DKA leads to excessive urination, which results in the loss of potassium and other electrolytes.

Hypokalemia can lead to cardiac arrhythmias and muscle weakness.

Therefore, replenishing potassium is crucial to maintaining normal physiological functions.

Choice C rationale:

Potassium replacement is not done to treat hyperkalemia in DKA.

DKA typically leads to hypokalemia, not hyperkalemia.

Hyperkalemia, or high potassium levels, is a less common complication in DKA.

Treating hyperkalemia may involve different interventions, but it is not the primary reason for potassium replacement in DKA.

Choice D rationale:

Potassium replacement is not done solely based on the client's request.

It is a medical decision made by healthcare providers based on clinical assessment and laboratory values.

Ignoring potassium replacement in DKA could lead to severe complications, so it is not a matter of personal preference.
