Midterm Study Guide 1. A patient needs 20 mg of a medication per kg. How many grams must you give to a patient that weighs 220 lbs? (HINT: There are 2.2 lbs per kg). 2. A client weighs 250 lbs. They require 200 mg/kg. The drug is available in a suspension of 3 grams per mL. How many teaspoons should be administered? (HINT: Note that there are 5 mL per tsp). Round to the nearest whole number. 3. Tritium is a radioactive isotope of hydrogen. After 15 years, it decays to one-half the original amount. After 30 years, it decays to one-fourth the original amount. If we start with 62 grams of Tritium, how much remains after 30 years? 4. 1 mL of water has a mass of 1 gram. What is the mass of 6 liters of water? 5. There is 3.785 liters in a gallon. How many liters are there in 8 gallons? 6. A medicine contains 4 grams per mL. What is the mass of 70 mL of this medication? 7. There are 1.06 quarts per liter. How many teaspoons are there in 0.8 gallons? (HINT: There are 5 mL per teaspoon and 4 quart per gallon). Round to the nearest whole number.  120 8. Convert 158 into a percent 9. A patient weighs 121 lbs. What is their weight in kilograms? (HINT: There are 2.2 lbs per kg). 10. Convert 98° Fahrenheit into Celsius. Use the equation F = 1.8 C + 32 11. The sum of two consecutive number a + b = 121 if b = a + 3, what is a? 12. If a candy bar contains 150 calories, how many calories would be contained in five candy bars? 13. If the ratio of A to B is 6 grams Sodium Chloride per 4 liters of waters. How many grams of Sodium Chloride are needed for a solution of 14 liters of water to maintain the ratio? 14. A $60 jacket is on sale for 83% off. How much will you pay for the dress? 15. Solve for x 2(X - 4) + 5(X + 8) = 3(X - 2) + 5X 1 5 16. Subtract the following fractions 7 − 12 17. Solve the following equation: 2x + 17 = 32 18. Solve the following equation: X + 52 = 12 −2 17 19. Solve for x 𝑥 = 9 160 20. Simplify the following fraction 140 1 3 8 21. Add 4 + 5 + 7 22. Solve the following equation: 6 (X + 2) = 18 23. Solve the following equation: 9 (X + 5) = 3 (4X - 8) 24. Solve for X: -4 (3x - 5) = -6x - 4(x +7) 8 25. Covert 2 7 to improper fraction  8 26. Solve the following equation: 7 = 𝑥 −2 27. 2 is 7 less than X. What is X? So 2 = X - 7 5𝑥+2 28. Solve for x 4 = 8 𝑥+4 29. Solve for x 𝑥−3 = 7 30. Give an example of each property. a.) Distributive b.)Associative c.) Commutative
