答え: C · Show them how to use the gown and gloves and how to clean their hands
Visitors are taught how to put on and remove PPE as required by the policy and how to perform hand hygiene, so they protect themselves and other patients.
答え: C · High-level disinfection
Items that touch mucous membranes or non-intact skin are semi-critical and need at least high-level disinfection after thorough cleaning. Inadequate reprocessing of endoscopes has caused outbreaks.
答え: B · A loose stool that takes the shape of the container
Only diarrhoeal stool (types 5–7 on the Bristol Stool Chart) is tested for C. difficile. The sample is collected in a clean pot without urine contamination.
答え: A · Category 2
Category 2 (Stage 2 in the US NPIAP system) is partial-thickness skin loss, seen as a shallow open ulcer with a pink-red bed or as a blister. Category 1 is intact skin; categories 3 and 4 are full thickness.
答え: B · Neisseria gonorrhoeae
Neisseria gonorrhoeae はグラム陰性球菌の対として見え、好中球の中にあることが多いです。Treponema はスピロヘータ、Chlamydia は細胞内寄生細菌、Trichomonas は原虫です。
答え: A · ペニシリンが作用する細胞壁がないから
Mycoplasma には細胞壁がないため、β-ラクタム系には標的がありません。代わりにリボソームに作用するマクロライド系やテトラサイクリン系を使います。
