Question 1 of 5

If Bill has 5.5 vacation days left for the rest of the year and 3.25 sick days left, how many days will he have off work if he uses all of this time?

Correct Answer: A

Rationale: To find the total days off work, we add Bill's remaining vacation days (5.5) and sick days (3.25). 5.5 + 3.25 = 8.75 Therefore, Bill will have 8.75 days off work if he uses all of his remaining vacation and sick days. Choice A (8.75) is correct because it accurately represents the total days off. Choices B, C, and D are incorrect as they do not correctly calculate the total days off based on the given information.

Question 2 of 5

A worker's schedule is written in military time, and shows their shift is from 1500 to 0100. When will they get off work?

Correct Answer: B

Rationale: The correct answer is B: 1:00 AM. In military time, 0100 translates to 1:00 AM. When converting military time to standard time, you simply drop the leading zero and read the remaining numbers as a regular time. Choice A is incorrect because it is vague and not a specific time. Choice C is incorrect as 3:00 AM is not represented by 0100 in military time. Choice D is incorrect because 12:30 AM is not the equivalent of 0100 in military time.

Question 3 of 5

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

Correct Answer: D

Rationale: The correct answer is D: .05 mL. To calculate the amount of insulin to administer, use the formula: Amount of insulin (mL) = Required units / Concentration of insulin (U/mL) Plugging in the values: Amount of insulin (mL) = 10 units / 200 U/mL = 0.05 mL Therefore, you would administer 0.05 mL of insulin. Choice A (.45 mL), B (.75 mL), and C (.25 mL) are incorrect as they do not align with the calculated value of 0.05 mL based on the given concentration and the required units of insulin.

Question 4 of 5

A hospital day staff consists of 25 registered nurses, 75 unlicensed assistants, 5 phlebotomists, 6 receptionists, and 45 physicians. On one particular day, the staff was at only 68% strength. How many people were working that day? (Round to the nearest whole number).

Correct Answer: B

Rationale: To find the total number of staff working, calculate 68% of the total staff. Total staff = 25 (RN) + 75 (assistants) + 5 (phlebotomists) + 6 (receptionists) + 45 (physicians) = 156 68% of 156 = 0.68 x 156 = 106.08 Rounded to the nearest whole number, the total staff working that day is 106. Therefore, the correct answer is B: 106. Summary: A: 102 - Incorrect, not the nearest whole number. C: 98 - Incorrect, below the calculated total. D: 110 - Incorrect, above the calculated total.

Question 5 of 5

Convert 0.007 kilograms to grams.

Correct Answer: A

Rationale: To convert 0.007 kilograms to grams, you should multiply by 1000 since there are 1000 grams in a kilogram. So, 0.007 kg * 1000 = 7 grams (Option A). Option B is incorrect as it incorrectly multiplies by 10 instead of 1000. Option C and D mistakenly move the decimal point to the wrong place.
