Which of the following might indicate hyperkalaemia?

Tingling of the lips and fingers can indicate hyperkalaemia, which is a condition characterized by elevated levels of potassium in the blood. This neurological symptom arises because high potassium levels can interfere with the normal electrical activity of nerve cells, leading to sensations such as tingling or numbness.

Understanding the symptoms associated with hyperkalaemia is critical for nursing practice, as this condition can have serious cardiovascular implications if not addressed promptly. Tingling or paresthesia may be an early warning sign, and recognizing it allows for timely intervention, which is essential in preventing further complications associated with elevated potassium levels.

In contrast, while frequent urination, chronic fatigue, and weight gain can be associated with various other conditions, they are not classic indicators of hyperkalaemia. Frequent urination could suggest dehydration or diabetes, chronic fatigue might indicate numerous underlying health issues, and weight gain could be linked to fluid retention or lifestyle factors. Recognizing the specific signs of hyperkalaemia, such as the tingling sensation, is vital for effective patient assessment and care.
