TEAS Practice Test Math

1. In a class of 48 students, there are 22 boys and 26 girls. What is the ratio of girls to boys in the class?

A. 26:11
B. 13:11
C. 13:22
D. 11:13

Correct answer: B

Rationale: To find the ratio of girls to boys, divide the number of girls by the number of boys: 26/22 = 13/11. Therefore, the correct ratio is 13:11. Choice A is incorrect as it includes an extra '00'. Choice C is incorrect as it reverses the order of girls to boys. Choice D is incorrect as it reverses the order and provides the ratio of boys to girls.

2. What is the author's point of view?

A. First person
B. Third person limited
C. Third person omniscient
D. Objective

Correct answer: B

Rationale: The passage is told from a third person limited point of view because the thoughts and perspectives of two specific characters, Michael and Lana June, are presented. The narrator provides insight into their thoughts, but remains limited to their viewpoints without revealing the thoughts of any other characters. This extract demonstrates the limited perspective by showing the inner thoughts of Michael and Lana June, indicating a third person limited narrative. Third person omniscient would involve knowing the thoughts of all characters, which is not the case here. First person would involve using 'I' to narrate, which is absent. Objective point of view would present only observable actions without any character's thoughts or feelings, which is not the case in this passage.

3. Which of the following statements regarding macrophages is incorrect?

A. They are found abundantly in the blood
B. They are larger than neutrophils
C. They are long-lived
D. They are made in the bone marrow as monocytes, called macrophages once they reach organs

Correct answer: A

Rationale: The correct answer is A. Macrophages are not found abundantly in the blood; they are present in tissues and organs. Macrophages are tissue-resident immune cells that play a key role in immune responses and are derived from monocytes produced in the bone marrow. Choice B is correct as macrophages are larger than neutrophils. Choice C is correct as macrophages are long-lived cells. Choice D is correct as macrophages originate in the bone marrow as monocytes and differentiate into macrophages once they migrate to various tissues and organs.

4. What do nociceptors detect?

A. Deep pressure
B. Vibration
C. Pain
D. Temperature

Correct answer: C

Rationale: Nociceptors are specialized sensory receptors that detect and transmit signals related to pain. These receptors are activated by noxious stimuli that can potentially cause tissue damage or injury, triggering the perception of pain in the brain. Therefore, the correct answer is 'Pain.' Choices A, B, and D are incorrect because nociceptors specifically respond to painful stimuli, not deep pressure, vibration, or temperature.

5. What is 0.5 liters equivalent to?

A. 500 ml
B. 50 ml
C. 5 ml
D. 0.5 ml

Correct answer: A

Rationale: 0.5 liters is equivalent to 500 milliliters. This conversion is straightforward because 1 liter equals 1000 milliliters. Choice A is correct because it accurately converts 0.5 liters into milliliters. Choices B, C, and D are incorrect as they do not correctly convert the given volume into milliliters.
