護理師正在教導一位新診斷為甲狀腺功能低下症的病人。護理師應解釋哪個症狀是由於代謝率降低所引起？
A nurse is educating a client newly diagnosed with hypothyroidism. Which symptom should the nurse explain as being caused by decreased metabolic rate?
- APalpitations心悸
- BConstipation✓ 正解便秘
- CWeight loss體重減輕
- DHeat intolerance不耐熱
甲狀腺功能低下症（Hypothyroidism）導致全身代謝率顯著降低。腸道蠕動減慢是代謝減緩的常見表現，常導致頑固性便秘。心悸、體重減輕與怕熱則是甲狀腺功能亢進（Hyperthyroidism）的典型症狀（代謝率過高）。護理師在衛教時，應協助病人了解這些變化與代謝率之間的關係，以便進行適當的生活方式管理。
Hypothyroidism causes a significant decrease in overall metabolic rate. Slowed intestinal motility is a common manifestation of this decreased metabolism and frequently produces stubborn constipation. Palpitations, weight loss, and heat intolerance are classic signs of hyperthyroidism (increased metabolic rate). When teaching, the nurse should help the client understand the relationship between these changes and metabolic rate to support appropriate lifestyle management.
