Math skill essentials

Mathematics

All nurses and nursing students will use mathematics for a number of calculations in nearly every area of their jobs. From Urology to Gastroenterology, nurses will use math to conduct dimensional analysis, read and analyze patient charts, make medication and weight conversions, and carry out day-to-day function.  Because math can be a challenging subject for many of us, it is important to have firm grasp on the subject prior to taking the HESI.  The math prep exams are filled with explanations that break each problem down so that it can be understood easily.

If

A

a = 2, b = 4

B

a = -2, b = 4

C

a = 2, b = -4

D

a = -2, b = -4

 

Rearrange the formula so that it is in the form of “a =

v^2=u^2+2as

A

a=frac{v-u}{2s}

B

a=frac{2(v^2-u^2)}{s}

C

a=frac{v^2-u^2}{2s}

D

a=frac{(v-u)^2}{2s}
