A nurse is collecting data from a client who has hypocalcemia. Which of the following findings should the nurse expect?
A.
Tingling of the lips
B.
Hypoactive bowel sounds
C.
Skeletal muscle weakness
D.
Decreased deep-tendon reflexes
The correct answer and Explanation is :
The correct answer is A. Tingling of the lips.
Explanation:
Hypocalcemia, or low levels of calcium in the blood, can lead to a variety of clinical manifestations due to calcium’s crucial role in neuromuscular function. The symptoms of hypocalcemia are often linked to increased neuromuscular excitability and altered cellular function.
- Tingling of the Lips: This symptom, known as paresthesia, is a classic sign of hypocalcemia. Calcium plays a key role in stabilizing cell membranes and regulating neuromuscular excitability. When calcium levels drop, increased excitability of nerve endings can cause abnormal sensations such as tingling or numbness, often in the lips and fingers.
- Hypoactive Bowel Sounds: This finding is more commonly associated with hypercalcemia (high calcium levels) rather than hypocalcemia. Hypercalcemia can lead to decreased gastrointestinal motility, resulting in hypoactive or absent bowel sounds. In hypocalcemia, bowel sounds are more likely to be normal or even increased due to heightened neuromuscular activity.
- Skeletal Muscle Weakness: While muscle weakness can occur in various conditions, including hypocalcemia, it is not the most characteristic finding. Hypocalcemia tends to increase neuromuscular excitability, which is more commonly associated with muscle cramps, spasms, or tetany rather than generalized weakness.
- Decreased Deep-Tendon Reflexes: This is also not a typical finding in hypocalcemia. In fact, hypocalcemia often leads to increased deep-tendon reflexes, reflecting the heightened neuromuscular excitability.
Overall, tingling of the lips is a specific and sensitive indicator of hypocalcemia due to the direct impact of low calcium levels on nerve function. Other symptoms of hypocalcemia include muscle cramps, tetany, and positive Chvostek’s and Trousseau’s signs.
