- BAssisting with daily hair combing協助每日梳理頭髮

禁食（NPO）病人因無法經口進食，唾液分泌量減少，口腔黏膜容易乾燥，這不僅會導致口臭，還會使口腔黏膜屏障受損，增加細菌滋生與感染風險。頻繁的口腔護理（Oral care）對於維護病人舒適度與預防感染至關重要。護理師應使用濕潤的棉棒或無酒精漱口水，協助病人清潔牙齒與舌面，保持黏膜濕潤與完整性，這是住院病人基本護理（Basic Care）的核心組成部分。
An NPO patient cannot take anything by mouth, so saliva production decreases and the oral mucosa is prone to dryness. This not only causes halitosis but also damages the mucosal barrier, increasing the risk of bacterial overgrowth and infection. Frequent oral care is therefore essential for maintaining the patient's comfort and preventing infection. The nurse should use moist swabs or alcohol-free mouthwash to help the patient clean the teeth and tongue, keeping the mucosa moist and intact. This is a core component of basic care for hospitalized patients.
