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。
Why is a baby of a mother with poorly controlled diabetes often large?
A woman in her first antenatal visit discloses that her partner hits her. What is the most appropriate nursing action?
某患者体重 60 kg,医嘱为单次给药 15 mg/kg。求剂量 D(mg)。
一袋输液在 500 mL 中含 50000 单位药物。医嘱为每小时 1500 单位。泵速 R 应设为多少 mL/h?
滴注以 75 gtt/min 的速度通过滴系数为 60 gtt/mL 的输液器。患者在 12 小时内接受多少毫升 V?
一袋液体在 100 mL 中含药 400 mg,以 8 mL/h 的速度输注。患者每小时获得多少毫克 D?
答案: A · Fetal hyperinsulinaemia acts as a growth hormone
Maternal glucose crosses the placenta, so the fetal pancreas makes extra insulin, which promotes growth and fat storage. After birth this extra insulin continues and can cause neonatal hypoglycaemia.
答案: B · Talk with her alone, assess her safety and offer support
Intimate partner violence often begins or worsens in pregnancy. The nurse should talk to her alone, assess safety, document carefully and offer support and local resources, without confronting the partner.
答案: D = 900 mg
剂量计算:给药量等于医嘱剂量除以现有药物的规格,再乘以该规格对应的量:给药量 = (医嘱剂量/储备规格) × 储备体积。始终统一单位(先把 g 换成 mg,mg 换成 mcg),并检查答案是否合理。
答案: R = 15 mL/h
剂量计算:给药量等于医嘱剂量除以现有药物的规格,再乘以该规格对应的量:给药量 = (医嘱剂量/储备规格) × 储备体积。始终统一单位(先把 g 换成 mg,mg 换成 mcg),并检查答案是否合理。
答案: V = 900 mL
Infusion rates: a pump is set in mL/h = volume/time in hours. A gravity drip is counted in drops per minute: gtt/min = volume (mL) × drop factor (gtt/mL)/time (min). The drop factor is printed on the tubing package: macrodrip sets deliver 10, 15 or 20 gtt/mL (blood sets often 10 gtt/mL in the US, 15 in the UK) and microdrip sets 60 gtt/mL. Always use the drop factor the question or package gives.
答案: D = 32 mg/h
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。
