PRACTICE MATH QUESTIONS
Complete the following dosage and solutions calculations within a 60-minute time
frame. You must show ALL calculations to receive credit for EVERY numeric
answer.
You may use a calculator. NO scientific calculators, cellular phones, PDA’s, etc.
will be allowed during the test. No borrowing of calculators during the exam will be
allowed. If you do not have a simple calculator, you must do it manually. The answer
entered in blank will be taken for grading.
ROUNDING RULE: Do not clear your calculator during the problem calculation. Carry
out to the hundredth place and round back to the tenth place for the final answer. You
will NOT be given credit for those problems missed due to rounding error. Your final
answers must not have “trailing zeros” after the decimal point. If the answer is less
than one, the answer must have a zero before the decimal. IV drip and IV pump
answers should always be whole numbers. Remember you cannot round time-hence
leave it to the hundredth place after a decimal! (ex: if the final answer is 24.3333333,
round it to 24.33 not 24.3 or 24). Any doses less than 1ml must be loaded in 1 ml
syringe, for which rounding must be done to hundredth place for example 0.333333
must be rounded to 0.33ml).
