In cases of hypokalemia, what might be administered?

Hypokalemia refers to a low level of potassium in the blood, which can lead to serious health issues including muscle weakness, cramping, and cardiac arrhythmias. Administering potassium-rich foods is the appropriate response to manage hypokalemia because these foods can help increase the body's potassium levels effectively. Foods such as bananas, oranges, spinach, and potatoes are all rich in potassium and can help replenish this essential electrolyte.

The other options, while potentially beneficial in different medical contexts, do not specifically address the issue of low potassium levels. Calcium supplements primarily support bone health and muscle function but do not contribute directly to potassium levels. Vitamin B12 injections are used to treat deficiency conditions and do not impact potassium. Iron tablets are used to treat iron-deficiency anemia and have no correlation with potassium levels. Thus, potassium-rich foods are the most effective means of addressing hypokalemia.
