CHEMISTRY AND PHYSICS FOR NURSE
ANESTHESIA COMPREHENSIVE EXAM
PAPER 2026 FULL QUESTIONS AND
CORRECT ANSWERS GRADED A+
●● What is algebra?.
Answer: Solving equations for an unknown quantity
●● What is scientific notation.
Answer: uses exponents for handling really large or really small
numbers
●● What is a mantissa?.
Answer: whole number and decimal part of a value not including place
holders and exponents
●● What kind of exponent does a number >1 have?.
Answer: Postive exponent
●● What kind of exponent does a number <1 have?.
Answer: Negative exponent
,●● What is a significant figure?.
Answer: digits in a measured value that have physical meaning and can
be reproduced
●● Why do we use significant figures?.
Answer: We use significant figures so scientists don't say that they're
measurements are more precise than they really are.
●● What are exact numbers?.
Answer: numbers not obtained through measurements-- easily countable
and hold value
●● What are the rules of significant figures?.
Answer: 1. All nonzero numbers are significant.
2. All zeros that are in between nonzero numbers are significant.
3. All trailing zeros that come after the last nonzero digit are significant
as long as there is a decimal in the number.
4. All leading zeros are not significant. Leading zeros are zeros that
come before the first nonzero number.
●● How many significant figures are in 37,000.
Answer: Possibly 2 or 5.. depends if they meant to place a decimal
,●● How many significant figures are in 705.001?.
Answer: 6
●● How many significant figures are in the measurement 811.40
grams?.
Answer: 4 significant figures
●● What is accuracy?.
Answer: how close a measurement is to the true value
An agreement between experimental data and "true value"
●● How do you assess accuracy?.
Answer: With percent error
●● How do you calculate precent error?.
Answer: ((measured value- true value)/true value) X100
●● What is precision?.
Answer: agreement between replicable measurements
●● How do we improve precision?.
, Answer: by careful lab technique
●● If a measurement is repeated, does this mean it is precise?.
Answer: No, it just means that it is reproducable-- getting closer to being
precise.
●● How do we quantify precision?.
Answer: By looking at standard deviation
the smaller the ratio of SD, the better the precision
●● What is the metric system sometimes called?.
Answer: MKS system (meter, kilogram, second)
●● What is the base unit for length?.
Answer: meter
●● What is the base unit for weight?.
Answer: kilogram
●● What is the base unit for time?.
Answer: second
