1. A farmer buys 3 bags of feed weighing 50 kilograms each. How much feed does he have in total?

• A. 100 kilograms
• B. 150 kilograms
• C. 200 kilograms
• D. 250 kilograms

Correct answer: B

Rationale: The correct answer is B: 150 kilograms. To find the total amount of feed, you need to multiply the number of bags by the weight of each bag. In this case, 3 bags * 50 kilograms each = 150 kilograms. Therefore, the farmer has a total of 150 kilograms of feed. Choice A (100 kilograms) is incorrect because it doesn't consider the total weight of all 3 bags. Choice C (200 kilograms) and Choice D (250 kilograms) are incorrect as they are miscalculations of the total weight of the feed.

2. A patient's height is 1.65 meters and their weight is 75kg. Calculate their BMI and interpret the result.

• A. 23.1 (Normal)
• B. 25.3 (Overweight)
• C. 27.7 (Overweight)
• D. 32.8 (Obese)

Correct answer: C

Rationale: To calculate BMI, divide weight (75kg) by height squared (1.65m^2) to get BMI (27.7). A BMI of 27.7 falls within the 'overweight' category (25-29.9 BMI). Choice A is incorrect as a BMI of 23.1 would be in the 'normal' range (18.5-24.9 BMI). Choice B is incorrect as 25.3 falls within the 'overweight' category. Choice D is incorrect as 32.8 is in the 'obese' category (>30 BMI). Therefore, the correct answer is C.

3. Olivia currently earns $51,200 in her job. If her salary increases by 4% this year, what will her new salary be?

• A. $52,348
• B. $52,736
• C. $53,040
• D. $53,248

Correct answer: D

Rationale: To find Olivia's new salary after a 4% increase, we calculate 4% of $51,200, which is 0.04 x $51,200 = $2,048. Adding this increase to Olivia's current salary gives us the new salary: $51,200 + $2,048 = $53,248. Therefore, Olivia's salary after the 4% increase will be $53,248. Choices A, B, and C are incorrect as they do not reflect the correct calculation for the new salary after a 4% increase.

4. How many grams are in 8 kilograms?

• A. 80000 grams
• B. 800 grams
• C. 80000 grams
• D. 8000 grams

Correct answer: D

Rationale: To convert kilograms to grams, you multiply by 1,000 since there are 1,000 grams in a kilogram. Therefore, 8 kilograms = 8 x 1,000 = 8,000 grams. The correct answer is 8,000 grams, which is option D. Choices A and C are incorrect as they incorrectly multiply by 10,000 instead of 1,000. Choice B is incorrect as it divides 8 by 10 instead of multiplying by 1,000.

5. The physician ordered 10 units of regular insulin, and 200 U/mL are on hand. How many milliliters will you give?

• A. .45 mL
• B. .75 mL
• C. .25 mL
• D. .05 mL

Correct answer: D

Rationale: To calculate the volume of insulin to be given, you can use the formula: Volume (mL) = (Ordered dose in units / Concentration of insulin in units/mL). Substituting the values, Volume (mL) = (10 units / 200 U/mL) = 0.05 mL. Therefore, the correct answer is 0.05 mL. Choices A, B, and C are incorrect because they do not match the calculated volume based on the provided information.
