子どもが加熱不十分なハンバーガーを食べた後に血性下痢を起こし、1 週間後に腎不全、貧血、血小板減少が見られます。最も可能性が高い生物はどれですか？
答え: C · Hold the bottle with the label in the palm and pour without touching the bowl
The nurse pours from a little height without touching the sterile bowl, avoiding splashes that would wet the field. Holding the label in the palm keeps it readable and free of drips.
答え: B · Remove contaminated PPE and wash the skin with soap and water at once
Skin exposure to hazardous drugs is washed immediately with soap and water after removing contaminated gloves or gown. The exposure is then reported and treated according to policy.
答え: C · From front to back
Cleaning from the urethra towards the anus moves bacteria away from the urinary tract and lowers the risk of urinary tract infection.
答え: C · Check the patient and probe, then warm the hand or move the probe
Cold peripheries, movement and nail varnish can give falsely low readings. The nurse assesses the patient first, then checks the waveform and probe site; a low reading is never ignored until it is explained.
答え: D · エルゴステロールは真菌の細胞膜にあるが、ヒトの細胞にはないから
真菌の膜はエルゴステロールを、ヒトの膜はコレステロールを含みます。アゾール系はエルゴステロールの合成を阻害し、アムホテリシンはエルゴステロールに結合するため、真菌を選択的に狙えます。
答え: B · O157:H7 などの志賀毒素産生性大腸菌
志賀毒素産生性大腸菌は腸と腎臓の細い血管を傷つけ、溶血性尿毒症症候群を起こします。牛が病原巣なので、加熱不十分な牛ひき肉が典型的な感染源です。
