ATI TEAS Math Practice Test Questions
Question 1 of 5
Simplify the following expression: (3)(-4) + (3)(4) - 1
Correct Answer: A
Rationale: To simplify the expression, we first multiply: (3)(-4) = -12, (3)(4) = 12. Substitute these values back into the expression: -12 + 12 - 1 = -1. Therefore, the correct answer is A (-1). Choices B, C, and D are incorrect as they do not match the calculated result of -1.
Question 2 of 5
Veronica has to create the holiday schedule for the neonatal unit at her hospital. 35% of her staff will be unavailable during the holidays, and of the remaining staff, only 20% are certified to work in the neonatal unit. What percentage of the total staff is certified and available to work?
Correct Answer: B
Rationale: To find the percentage of total staff certified and available to work, we first calculate the percentage of staff available: 100% - 35% = 65%. Then, we find the percentage of the remaining staff who are certified: 65% x 20% = 13%. Therefore, the correct answer is B (13%). Choice A (7%) is too low, as it only considers the percentage of certified staff. Choice C (65%) is incorrect as it represents the percentage of total staff available, not certified. Choice D (80%) is incorrect as it does not take into account the percentage of staff who are both certified and available.
Question 3 of 5
Simplify the following expression: (3)(-4) + (3)(4) - 1
Correct Answer: A
Rationale: To simplify the expression, we first multiply: (3)(-4) = -12, (3)(4) = 12. Substitute these values back into the expression: -12 + 12 - 1 = -1. Therefore, the correct answer is A (-1). Choices B, C, and D are incorrect as they do not match the calculated result of -1.
Question 4 of 5
Simplify the following expression:
Correct Answer: A
Rationale: To simplify the expression, convert the mixed number 1 9/16 to an improper fraction: 1 * 16 + 9 / 16 = 25/16. Thus, the correct answer is A: 1 9/16. Option B (1 1/4) and Option C (2 1/8) do not represent the correct simplification of the given expression. Option D (2) is also incorrect as it does not accurately represent the simplified form of the expression.
Question 5 of 5
A patient was taking 310 mg of an antidepressant daily. The doctor reduced the dosage by 1/5, and then reduced it again by 20 mg. What is the patient's final dosage?
Correct Answer: C
Rationale: To find the final dosage, we first reduce 310 mg by 1/5, which is 310 * (1 - 1/5) = 248 mg. Then, we further reduce it by 20 mg, resulting in 248 - 20 = 228 mg. Therefore, the patient's final dosage is 228 mg. Option A (20 mg) is incorrect because it only accounts for the second reduction. Option B (42 mg) is incorrect as it doesn't consider both reductions. Option D (248 mg) is incorrect as it doesn't factor in the second reduction.
