1.护理预科数学(入学考试)
答案: t = 1.75 h
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。
十分位位上的数字
12.7756 → 7
只看下一位数字
12.7756 → 7
7 大于或等于 5,所以 7 进一。
后面的数字(56)不考虑:只取整一次,不要逐位取整。
取整
x = 12.8 mL
答案
x = 12.8 mL
4.护理数学与单位换算
答案: V = 472.5 mL
家用计量和体重:护理考试使用取整的等量关系:1 茶匙(tsp)= 5 mL,1 汤匙(tbsp)= 15 mL = 3 tsp,1 液量盎司(fl oz)= 30 mL = 2 tbsp,1 杯 = 8 fl oz = 240 mL。体重方面,1 kg = 2.2 lb,1 lb = 16 oz;长度方面,1 英寸 = 2.54 cm。设置换算时,要让你不需要的单位相互约去。
每一项的 mL 数
1½ tsp = 1.5·5 = 7.5 mL
1 tbsp = 1·15 = 15 mL
3 fl oz = 3·30 = 90 mL
1½ 杯 = 1.5·240 = 360 mL
相加
V = 7.5 + 15 + 90 + 360 = 472.5 mL
答案
V = 472.5 mL
5.阅读理解(入学考试)

9.英语语法与语言运用(入学考试)
答案: C · “If you feel pain,” the nurse said, “press the button.”
为什么是这个答案
When a speech tag interrupts one quoted sentence, commas go on both sides of the tag, and the second part continues in lowercase. C turns the first part into a fragment. British (logical) style may put the first comma outside the marks, but American style keeps it inside.
答案
C · “If you feel pain,” the nurse said, “press the button.”
10.英语语法与语言运用(入学考试)

答案
D · It keeps membrane fluidity stable as temperature changes
16.护理入学考试生物
答案: B · 3/4
为什么是这个答案
Bb × BB gives all offspring with at least one B, so 1 for trait B. Aa × Aa gives 3/4 with at least one A. 3/4 × 1 = 3/4 show both dominant traits.
答案
B · 3/4
17.护理入学考试化学
答案: B · It raises the boiling point slightly
为什么是这个答案
Dissolved solute lowers the vapour pressure, so a higher temperature is needed to boil. This boiling point elevation is a colligative property, like freezing point depression.
答案
B · It raises the boiling point slightly
18.护理入学考试化学
答案: B · H₂, because 1 mol of N₂ would need 3 mol of H₂
为什么是这个答案
1 mol N₂ needs 3 mol H₂, but only 2 mol are present, so H₂ runs out first and is limiting. Having fewer moles of N₂ does not make it limiting; the ratio decides.
答案
B · H₂, because 1 mol of N₂ would need 3 mol of H₂
