الإجابة: A. Hypokalaemia
His K is already low-normal (3.4). Starting an insulin infusion shifts K into cells, so hypokalaemia is the expected treatment complication. Potassium should be replaced with the fluids and monitored closely. Hypernatraemia and worsening hyperglycaemia are not typical complications.

A
ليش صح
Insulin shifts potassium into cells, causing hypokalemia very rapidly; his K is already 3.4, so potassium must be replaced and monitored.

B
ليش غلط
Hyperkalemia can be present at the start because of acidosis, but insulin then shifts K into cells, lowering it; his K is already 3.4.

C
ليش غلط
Fluids and insulin lower glucose; the listed treatment complications are cerebral edema (too rapid a fall in glucose) and hyperchloremic acidosis, not hyperglycemia.

D
ليش غلط
Sodium is low because of hyperglycemia and normalizes with treatment; hypernatremia is not the listed problem.
