Answers with Verified Solutions | Latest
Updated 2026
What is body mass index? A measure of body weight relative to
height
What is the equation for BMI BMI = Weight (kg)/ height (m)^2
(kg/m)^2
What is the equation for BMI in BMI = weight (lbs)/height (inch)^2
regards to inches and pounds? to convert to kg/m^2 multiply by 703
What are the different categories < 18.5 = Underweight
for 19.5-24.9 = Normal
BMI? 25-29.9 = Overweight
30 and above = Obese
A male patient comes to the - 6'7'' = 79 inches
pharmacy and tells the pharmacist - BMI = 250/(79)^2 * 703 = 28.16 = 28
he is 6'7'' tall and weighs 250 BMI = 28 ---> Overweight
pounds.
His waist circumference is 43
inches.
Calculate his BMI. Round to the
nearest whole number. What is the
patient's category in regards to
their
BMI?
,Calculate the BMI for a male who - 6'0'' = 72 inches
is - BMI = [198/(72^2)] *703 = 26.85 = 26.9
6' tall and weighs 198 pounds. BMI of 27 = Overweight
Round
to the nearest tenth. What
category
do they fall under?
What is actual body weight (also Weight of a patient on a weighed scale
known as total body weight)?
What is ideal body weight? The optimal weight for one's height, age,
sex, and
body build.
What is the equation for ideal body IBW (males) = 50 kg + 2.3*(number of
weight? inches greater
than 5 feet)
IBW (females) = 45.5 kg + 2.3*(number of
inches
greater than 5 feet)
What is adjusted body weight? Weight used when patients are obese or
overweight
What is the equation for adjusted Adj = IBW + 0.4 * (TBW - IBW)
body weight?
When do you use TBW? When TBW < IBW or TBW = IBW
When do you use ABW? When TBW is 120% or greater than IBW
, Which drugs use TBW no matter - Vancomycin
what the patient weighs? - LMWH
- UFH
What medications require IBW if - Aminophylline
TBW - Theophylline
is greater than 120%? - Acyclovir
- Levothyroxine
What medications require adjusted - Aminoglycosides
body weight (ABW)?
A female patient is to receive 5 - IBW = 45.5 + (2.3*7) = 61.6 kg
mg/kg/day of theophylline. The - TBW = 243/2.2 = 110.5 kg
patient is 5'7'' and weighs 243 - 110.5/61.6 = 1.8 = 180% more than IBW
pounds. Calculate the daily - Theophylline uses IBW
theophylline dose the patient - 61.6 kg * 5mg/kg/day = 308 mg/day
should
receive?
A 34 year old male (height 6'7'', - IBW = 50 + (2.3*19) = 93.7 kg
weight 287 pounds) is hospitalized - TBW = 287/2.2 = 130.45 kg
after a motor vehicle accident. He - 130.45/93.7 = 1.4 = 140% more than IBW
develops a Pseudomonas - ABW = 93.7+(0.4*(130.45-93.7)) = 108.4
aeruginosa infection. The kg
physician - 2 mg/kg * 108.4 kg = 216.8 mg = 220
orders tobramycin 2 mg/kg IV mgIV Q8h
Q8h.
Calculate the tobramycin dose.
Round to the nearest 10
milligrams.
