产科护理
方法
- 把产妇放在时间轴上定位:孕周、产程阶段或产后第几天,再判断此时什么是正常的。
- 找出处于危险中的对象:母亲、胎儿或新生儿,或者其中不止一个。
- 把发现与其原因联系起来:减速用 VEAL CHOP,出血用四个 T,产后用 BUBBLE-HE。
- 优先选择改善血流和氧合的措施(侧卧、停用缩宫素、宫底按摩),然后再升级处理。
公式表、每个专题的关键方法步骤和 6 道练习题,完整解答附在最后。
During the hip examination, the nurse hears a "clunk" as the newborn's hip is abducted. What does this suggest?
At a booking visit, a woman says she drinks heavily most weekends. Which nursing response is most appropriate?
一名体重 39 kg 的儿童按 2 mg/kg 处方用药。原液浓度为 10 mg/mL。请抽取剂量:应给多少体积 V?
处方剂量为 0.68 mg。安瓿每 mL 含 1000 微克。请用 1 mL 注射器抽取剂量:应给多少体积 V?
用滴系数为 10 滴/mL 的输液器在 10 小时内输入 1000 mL。求滴速 R(滴/分)。 取整到最接近的整数。
一袋中含有 1 g 药物,溶于 500 mL。医嘱为每分钟 3 mg。泵速 R 应设为多少 mL/h?
答案: D · Developmental dysplasia of the hip
A clunk with the Ortolani or Barlow manoeuvre suggests a dislocated or dislocatable hip. Asymmetrical skin folds and limited abduction are other signs. Early ultrasound and treatment give good results.
答案: A · Explain the risks and refer her for support to stop
Alcohol can harm the fetus throughout pregnancy, and stopping at any point reduces the risk. The nurse gives clear, non-judgemental information and refers her to support services.
答案: V = 7.8 mL
抽取剂量:体积 = (处方剂量/药物浓度) × 药物体积。先换算成相同的单位,再检查该体积是否适合注射器,并落在它的某一个刻度上。
在这支 10 mL 的注射器上,每条小刻度线代表 0.2 mL。
答案: V = 0.68 mL
抽取剂量:体积 = (处方剂量/药物浓度) × 药物体积。先换算成相同的单位,再检查该体积是否适合注射器,并落在它的某一个刻度上。
答案: R = 17 gtt/min
输注速率:输液泵按 mL/h = 体积/时间(小时)设定。重力滴注按每分钟滴数计:gtt/min = 体积 (mL) × 滴系数 (gtt/mL)/时间 (min)。 滴系数印在输液器包装上:普通输液器为 10、15 或 20 gtt/mL(输血器在美国常为 10 gtt/mL,在英国为 15),微量输液器为 60 gtt/mL。务必使用题目或包装给出的滴系数。
床旁取最接近的整滴:17 滴/分。
答案: R = 90 mL/h
Dose-based infusions: concentration = amount of drug in the bag/bag volume. Pump rate (mL/h) = dose per hour/concentration, and dose per hour = mL/h × concentration. Convert per-minute doses to per-hour (× 60) and keep the mass units the same (1 g = 1000 mg, 1 mg = 1000 mcg).
