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.

Correct Answer: A

Rationale: To add 1.332 and 0.067, start from the rightmost digit and move left. Add 2 + 7 (9), then 3 + 6 (9), and 1 + 0 (1). The sum is 1.399, making choice A the correct answer. Choices B, C, and D are incorrect as they do not match the correct sum obtained through the addition process.

Correct Answer: A

Rationale: To add 9.43 and 11.3, align the decimal points and add the numbers as follows: 9.43 +11.30 ------- 20.73 Therefore, the correct answer is A: 20.73. The other choices are incorrect as they do not match the sum obtained through the addition process. B: 21.3 does not account for the decimal place in 9.43. C: 22 is the sum of the whole numbers without considering the decimal values. D: 19.5 is the sum if the decimal values are not accounted for.

Correct Answer: C

Rationale: To convert 2 teaspoons to milliliters, we need to know that 1 teaspoon is approximately 4.93 milliliters. Therefore, 2 teaspoons would be 2 * 4.93 = 9.86 milliliters. The correct answer is C (9.86 milliliters). Choice A (4.3 milliliters) is incorrect because it is too low based on the conversion factor. Choice B (9 milliliters) is close but not accurate, as the exact conversion gives 9.86 milliliters. Choice D (4 milliliters) is also incorrect as it is lower than the actual conversion.
