HOSA Medical Math
Practice Test for NLC
Directions: This is a 20-item PRACTICE TEST for HOSA members who wish to become
familiar with the format of using a grid Scantron answer form.
Please use the sample grid to write and bubble-in your responses, and then check your work.
This format will be used for the Medical Math event at the National Leadership Conference and
MAY be used at your State Leadership Conference (check with your state advisor). There are
50 test items to solve and fill in on the grid, and 10 multi-step tie-breaker questions with fill-in-
the-blank responses.
Unless otherwise indicated, round to the nearest whole number.
1. Mark weighed 240 pounds when he started to exercise daily and eat a healthy diet. After
six months he lost 32% of his body weight. How many pounds did he lose? (Round to the
nearest tenth.)
2. How many milligrams in 70 mcg? (Round to the nearest hundredth.)
3. Convert 1030 Fahrenheit to 0Celsius. (Round to the nearest tenth.)
4. A pathology sample weighs 2 ½ ounces. What is the weight in grams?

0.2 mg/kg q4h PRN. How many milliliters per dose would be given if the concentration is
2 mg/ml?
8. What is the correct fractional equivalent of the ratio 2:7?
