SATA：每个选项都是它自己的一道真假题
SATA: Every Option Is Its Own True-or-False Question
☑️ 六个选项，“选择所有适用项”，还有一种隐隐的感觉，觉得选三个不知为何就是惯例。不存在什么惯例。有一条计分规则，一旦你了解它，恐慌就会消失。
☑️ Six options, 'select all that apply', and a creeping suspicion that picking three is somehow the norm. There is no norm. There is a scoring rule, and once you know it, the panic goes away.
💡 核心要点
把每个选项都当作针对这位患者的独立真假陈述来读。加减分计分会惩罚猜测，所以只选择你能站得住脚的选项。
Read each option as its own true-or-false statement for this client. Plus/minus scoring punishes guesses, so select only what you can defend.
🧠 为什么重要
在选择所有适用项（SATA）的题目中，任意数量的选项都可能正确，从一个到全部都有可能。把每个选项都当作关于题干情境的一个独立的真或假陈述来对待，永远不要数你已经选了几个。选择所有适用项的题目采用加减分计分：每个正确选择得一分，每个错误选择扣一分，题目得分永远不会低于零，所以一次鲁莽的多选可能会抵消一个正确选项。相比之下，明确要求选择数量的题目采用零一计分：每个正确选择得一分，错误选择不得分，但也不扣分。无论哪种情况，对每个选项要问的问题都是“这对这位患者此刻是否成立？”留意那些总体上正确、但对题干中的患者却错误的选项（正常发现出现在错误的年龄组，或被病史禁忌的干预措施）。有些题目会写“选择N项”，并明确告诉你选几项，那就恰好选那么多项。
In a SELECT ALL THAT APPLY item, any number of options can be correct, from one to all of them. Treat each option as an independent TRUE or FALSE statement about the situation in the stem; never count how many you have chosen. Select-all items use PLUS/MINUS scoring: each correct selection earns a point and each incorrect selection subtracts one, with the item score never falling below zero, so a reckless extra click can cancel a correct one. Items that name how many to choose use ZERO/ONE scoring instead: each correct choice earns a point, and a wrong choice earns nothing but subtracts nothing. Either way, the question to ask for each option is 'Is this true for THIS client right now?' Watch for options that are correct in general but wrong for the stem's client (a normal finding in the wrong age group, an intervention contraindicated by the history). Some items say 'select N' and tell you exactly how many to choose; then choose exactly that many.
🏥 真实场景
🧾 题干：一名服用furosemide的心力衰竭患者。“哪些发现需要随访？”“选择所有适用项。”选项：一夜之间体重增加3磅（正确），钾2.9（正确），心率72（错误），双侧湿啰音（正确），尿量60 mL/hr（错误），报告肌肉痉挛（正确：低钾血症）。四个正确，两个错误，一个一个地判定。数字四从来不是目标，它只是结果。
🧾 Stem: a client with heart failure on furosemide. 'Which findings require follow-up? Select all that apply.' Options: weight gain of 3 pounds overnight (true), potassium 2.9 (true), heart rate 72 (false), bilateral crackles (true), urine output 60 mL/hr (false), reports of muscle cramps (true: hypokalemia). Four true, two false, decided one at a time. The number four was never the goal; it was the result.
📌 要点总结
- 任意数量的选项都可能正确Any number of options can be correct
- 每个选项对题干中的患者而言非真即假Each option is true or false for the client in the stem
- 多余的猜测可能会扣分，只选你能站得住脚的Extra guesses can subtract points; choose what you can defend
📖 本课术语
选择所有适用项（SATA） (Select all that apply (SATA)): 这类题目中任意数量的选项都可能正确，因此每个选项都要单独判断对错。
✅ 自我测试
应对“选择所有适用项”题目的最佳方法是什么？What is the best approach to a 'select all that apply' item?
- 选择听起来最医学化的选项Select the options that sound most medical
- 选择每一个选项，因为会给部分分数Select every option, since partial credit is given
- 把每个选项单独当作真或假来判断Judge each option as true or false on its own
- 总是至少选择三个选项Always select at least three options
答案: C · 把每个选项单独当作真或假来判断
把每个选项当作关于题干中患者的独立真假陈述来评估，可以防止选得太少和选得太多；在加减分计分下，全部选择会丢分。
Evaluating each option as a separate true-or-false statement about the client in the stem prevents both under- and over-selection; selecting everything loses points under plus/minus scoring.
在加减分计分下，当考生在选择所有适用项的题目中选了一个错误选项时，会发生什么？Under plus/minus scoring, what happens when a candidate selects an incorrect option on a select-all item?
- 什么也不会，只有正确选择才计分Nothing; only correct selections count
- 整道题记为零分The entire item is scored zero
- 考生必须重新开始这道题The candidate must restart the item
- 从题目得分中扣一分One point is subtracted from the item score
答案: D · 从题目得分中扣一分
错误选择会抵消正确选择，这就是为什么草率的多选会造成伤害；题目得分不会低于零。
Incorrect selections cancel correct ones, which is why careless extra selections hurt; the item score cannot fall below zero.
一道题写着“选择3个需要立即随访的发现”。考生应该选择多少个？An item reads 'Select the 3 findings that require immediate follow-up.' How many should the candidate select?
- 至少3个At least 3
- 恰好3个Exactly 3
- 不超过2个No more than 2
- 看起来相关的有多少选多少As many as seem relevant
答案: B · 恰好3个
“选择N项”的题目会指定数量，恰好选那么多。选择至少3个会招致超出指定数量的额外选择，而这些额外选择会扣分。
'Select N' items specify the number; choose exactly that many. Selecting at least 3 invites extra choices beyond the stated number and those extra selections count against the score.
