Math HESI A2 Practice Test

Correct Answer: C

Rationale: To find the total words typed in 20 minutes, multiply words per minute by minutes: 45 words/minute x 20 minutes = 900 words. Thus, the correct answer is C (900 words). A is incorrect as it miscalculates the total. B is incorrect as it underestimates the total. D is incorrect as it duplicates option A.

Correct Answer: C

Rationale: The nurse works from 1300 to 2000, which translates to 1 PM to 8 PM. To calculate the hours worked, subtract the start time from the end time: 8 PM - 1 PM = 7 hours. Therefore, the correct answer is C (7 hours). Choice A (8 hours) is incorrect as it includes the end time, Choice B (11 hours) is incorrect as it adds extra hours, and Choice D (12 hours) is incorrect as it adds both the start and end times.

Correct Answer: A

Rationale: To convert 5/8 to a decimal, divide 5 by 8, which equals 0.625. The correct answer is A (0.625) because it is the result of dividing the numerator by the denominator. Choice B (0.5) is incorrect as 5/8 is not equal to 0.5. Choice C (0.4) and choice D (0.75) are also incorrect as they do not represent the equivalent decimal value of 5/8.

Correct Answer: D

Rationale: To convert Celsius to Fahrenheit, you use the formula: Fahrenheit = (Celsius x 1.8) + 32. Given the patient's temperature is 38.5 degrees Celsius, Fahrenheit = (38.5 x 1.8) + 32 = 104.9 degrees Fahrenheit (Option D). Options A, B, and C are incorrect as they do not match the correct conversion using the formula.

Correct Answer: A

Rationale: To divide 5 3/4 by 1/2, we convert 5 3/4 to an improper fraction as 23/4. Then, we divide 23/4 by 1/2, which is equivalent to multiplying by the reciprocal of 1/2, which is 2. Therefore, 23/4 * 2 = 46/4 = 11 1/2. The correct answer is A. Other choices are incorrect as they do not result from the correct calculation process.
