HESI A2 Quizlet Math Questions

Question 1 of 5

The physician orders 1000 mg of Benadryl liquid; 1 g = 1 tsp. How many teaspoons will you give?

Correct Answer: C

Rationale: To convert 1000 mg to teaspoons, we use the given conversion factor of 1 g = 1 tsp. First, we convert mg to grams by dividing 1000 mg by 1000 (1 g = 1000 mg), which equals 1 g. Since 1 g is equivalent to 1 tsp according to the conversion factor, the correct answer is 1 tsp. Choice A (.75 tsp) is incorrect because 1 g is equivalent to 1 tsp, not .75 tsp. Choice B (1.5 tsp) is incorrect as 1000 mg equals 1 g, which corresponds to 1 tsp, not 1.5 tsp. Choice D (1.25 tsp) is incorrect because 1000 mg converts to 1 tsp, not 1.25 tsp.

Question 2 of 5

Last night at the hospital, 76 babies were born. Of the births, 45% were girls. How many boys were born last night? (Round your numbers to the nearest whole number).

Correct Answer: A

Rationale: To find the number of boys born last night, we first calculate the number of girls born, which is 45% of 76 (0.45 * 76 = 34.2). Since we can't have a fraction of a baby, we round this to the nearest whole number, which is 34. Therefore, the remaining babies (76 - 34) are boys, giving us a total of 42 boys born last night. Choice A (42) is correct. Choices B, C, and D are incorrect as they do not correctly calculate the number of boys born based on the information provided.

Question 3 of 5

What is the freezing point of water in degrees Celsius?

Rationale: Failed to generate a rationale after 5 retries.

Question 4 of 5

What number is represented by the Roman Numerals XLIV?

Correct Answer: C

Rationale: The Roman numeral XLIV represents the number 44. Here's the breakdown: - "XL" is 40 in Roman numerals. - Adding "IV" (4) to XL gives us 44. Therefore, the correct answer is C. Other choices are incorrect because: - A (34): This is incorrect as XL is 40, not 30. - B (54): XL is 40, not 50. - D (24): XL is 40, not 20.

Question 5 of 5

An IV drip delivers medication at a rate of 40 drops per minute. Each drop contains 0.05 milliliters of the medication. How many milliliters of medication are delivered in one hour?

Correct Answer: D

Rationale: To calculate the amount of medication delivered in one hour, first find the amount delivered in one minute: 40 drops/min * 0.05 mL/drop = 2 mL/min. Then, multiply by the number of minutes in an hour: 2 mL/min * 60 min = 120 mL. Therefore, the correct answer is D (120 milliliters). Summary: A: Incorrect. Not enough medication delivered. B: Incorrect. Not enough medication delivered. C: Incorrect. Too low of an amount delivered.
