1.护理预科数学(入学考试)
答案: x = 720 min
单位换算:乘以一个等于 1 的因子,写成能约去旧单位的形式:3 ft × 12 in/1 ft = 36 in。公制长度:1 km = 1000 m,1 m = 100 cm = 1000 mm,1 cm = 10 mm。美制:1 ft = 12 in,1 yd = 3 ft,1 mi = 5280 ft;1 gal = 4 qt,1 qt = 2 pt,1 pt = 2 cups;1 ton = 2000 lb。时间:1 h = 60 min,1 min = 60 s,1 day = 24 h,1 week = 7 days。单位越小,数值越大。
取整:看舍入位后面的那个数字:5 或更大则进位,4 或更小则保持原数字不变。只对最终答案取整,绝不对中间步骤取整。典型的考试规则:1 mL 或以上的体积取到十分位,低于 1 mL 的体积取到百分位,滴速取整到整滴,体重取到一位小数;务必遵循题目所规定的规则。
百分位位上的数字
0.18044 → 8
只看下一位数字
0.18044 → 0
0 小于或等于 4,所以 8 不变。
后面的数字(44)不考虑:只取整一次,不要逐位取整。
取整
x = 0.18 mL
答案
x = 0.18 mL
4.护理数学与单位换算
答案: Hb = 133 g/L
量纲分析:先写出已知量,再乘以写成分数形式的换算系数(例如 60 min/1 h 或 1 mg/1000 mcg),使每个不需要的单位在分子和分母各出现一次并相互约去。只剩下所求单位时再计算。使用题目给出的等量关系,只对最终答案取整。
转换
Hb = 13.3 g/dL × 10 dL/L = 133 g/L
答案
Hb = 133 g/L
5.阅读理解(入学考试)

答案
A · hearing
10.英语语法与语言运用(入学考试)
答案: A · has
为什么是这个答案
A fraction takes its number from the noun after “of”. “Medication” is singular here, so the verb is “has”.
答案
A · has
11.人体解剖学
答案: A · 肘正中静脉
为什么是这个答案
肘正中静脉在头静脉和贵要静脉之间斜穿肘窝。它位置表浅、管径大且较固定,因此容易穿刺。
答案
A · 肘正中静脉
12.人体解剖学
答案: A · 右主支气管更粗、更短、更陡直
为什么是这个答案
右主支气管更粗、更短,与气管的走向更接近一条直线,因此误吸的物体往往落入其中。
答案
A · 右主支气管更粗、更短、更陡直
13.人体生理学

为什么是这个答案
优势卵泡分泌的雌激素不断升高,触发腺垂体释放 LH 峰,约一天后引起排卵。
答案
C · 黄体生成素(LH)峰
14.人体生理学
答案: B · 变得非常高,起无效腔的作用
为什么是这个答案

答案
B · 变得非常高,起无效腔的作用
15.护理入学考试生物
答案: D · Prophase

答案
D · Prophase
16.护理入学考试生物
答案: C · Down syndrome, with 47 chromosomes
为什么是这个答案
Trisomy 21 causes Down syndrome. It usually results from nondisjunction during meiosis, giving a gamete with an extra chromosome 21 and a zygote with 47 chromosomes.
答案
C · Down syndrome, with 47 chromosomes

答案
C · 它吸收热量,所以周围环境感觉更冷
18.护理入学考试化学
答案: C · O²⁻
为什么是这个答案
With the same 10 electrons, the ion with the fewest protons holds them least tightly. O²⁻ has only 8 protons, so it is largest; Mg²⁺ with 12 protons is smallest.
