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。
Which reflex causes the newborn's toes to fan out when the sole is stroked from heel to toe?
A woman with postpartum psychosis is being admitted with her baby to a mother and baby unit. Which statement is accurate?
某患者体重 25 kg。医嘱剂量为每天 7.5 mg/kg,分 2 次等量给药。每次给多少毫克 D?
处方剂量为 1.86 mg。安瓿每 mL 含 2000 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 15 滴/mL 的输液器在 8 小时内输入 1000 mL。求滴速 R(滴/分)。 取整到最接近的整数。
医嘱要求在 10 小时内输入 500 mL。4 小时后你发现袋中还剩 350 mL,而输液仍须按时完成。 原来的泵速必须提高百分之多少 Δ?
答案: C · Babinski reflex
The Babinski reflex, fanning of the toes with dorsiflexion of the big toe, is normal in infants until about 1 year. Pressing the sole near the toes gives the plantar grasp instead.
答案: D · It is an emergency that usually starts within two weeks
Postpartum psychosis is rare but serious, typically starting suddenly within the first two weeks with mania, confusion, hallucinations or delusions. Bipolar disorder is a major risk factor. Urgent treatment is needed to keep mother and baby safe.
答案: D = 93.75 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: V = 0.93 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 = 31 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:31 滴/分。
答案: Δ = 16.67 %
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.
许多医院允许在不重开医嘱的情况下进行不超过 25% 的此类调整;请查阅本院规定。
