- AApical pulse rate✓ 正解心尖脈率
- BRespiratory rate呼吸速率
- CBlood pressure血壓

地高辛（Digoxin）具有正性肌力與負性變時作用，能增加心肌收縮力並減慢房室結傳導。由於其治療指數窄（Narrow therapeutic index），極易產生毒性。心動過緩（Bradycardia）是地高辛中毒的常見徵兆，因此在給藥前必須確實測量心尖脈（Apical pulse）整整一分鐘，以確保給藥的安全性。
Digoxin has positive inotropic and negative chronotropic effects, increasing myocardial contractility while slowing AV conduction. Because of its narrow therapeutic index, toxicity occurs easily, and bradycardia is a common sign. The nurse must assess the apical pulse for a full minute before administration to ensure safety.
