Clinical signs of hypokalemia include:

Weakness and flattened T waves are clinical signs associated with hypokalemia, which is a condition characterized by low levels of potassium in the blood. Potassium plays a crucial role in maintaining normal electrical activity in the heart and in muscle function. When potassium levels drop, patients may experience muscle weakness, fatigue, and cramps due to the impaired electrical conduction in muscle cells.

Flattened T waves on an electrocardiogram (ECG) can indicate changes in myocardial repolarization caused by low potassium levels. In some cases, this can progress to more serious arrhythmias if left untreated. Recognizing these signs is vital for timely intervention in hypokalemia, as it can lead to potentially life-threatening complications such as cardiac arrest.

The other clinical signs presented in the options do not accurately describe hypokalemia. For instance, coma and severe peripheral edema are more indicative of other conditions such as severe hyponatremia or heart failure. Convulsions and absent P waves relate to different electrolyte imbalances, specifically hyperkalemia or other genetic cardiac issues. Muscle cramps and peaked T waves are more commonly associated with hyperkalemia rather than hypokalemia. Therefore, the proper identification of weakness and flattened T waves is essential for diagnosing and managing hyp
