ATI TEAS Practice Science Test Questions
Question 1 of 5
Which of the following correctly orders the route of a fetus during childbirth?
Correct Answer: A
Rationale: The correct answer is A: Uterus, cervix, vagina. During childbirth, the fetus travels from the uterus through the cervix and then out through the vagina. The uterus is where the fetus develops, the cervix dilates to allow passage, and the vagina is the birth canal. The other choices are incorrect because they do not follow the correct route of the fetus during childbirth. Choice B (Cervix, uterus, vagina) is incorrect as the fetus does not move from the cervix to the uterus during childbirth. Choice C (Uterus, vas deferens, vagina) is incorrect as the vas deferens is part of the male reproductive system and not involved in childbirth. Choice D (Ovary, fallopian tube, uterus) is incorrect as this represents the path of the egg during fertilization, not the route of the fetus during childbirth.
Question 2 of 5
At which of the following ages would ossification most likely take place to replace cartilage at the growth plate?
Correct Answer: B
Rationale: The correct answer is B (18). Ossification at the growth plate occurs during adolescence when bones undergo rapid growth and development. At around age 18, the growth plates begin to close as bone growth slows down, leading to ossification replacing cartilage. At age 5 (A), the growth plates are still actively contributing to bone growth. At age 42 (C) and 91 (D), ossification is more likely related to aging processes and repair rather than growth plate replacement.
Question 3 of 5
Why is an extensive network of blood vessels necessary to supply the endocrine glands?
Correct Answer: B
Rationale: The correct answer is B because endocrine glands release hormones directly into the bloodstream. Therefore, an extensive network of blood vessels is necessary to facilitate the direct release of hormones into the blood for systemic circulation. The other choices are incorrect because: A: Filtering waste from the blood is the function of the kidneys, not the endocrine glands. C: Blood does not "empty" into the endocrine system; rather, hormones are released into the bloodstream. D: Endocrine glands do not filter waste; instead, they produce and release hormones into the blood for various physiological functions.
Question 4 of 5
Which statement confirms that the cell membrane is selectively permeable?
Correct Answer: D
Rationale: The correct answer is D because it specifically refers to the process of selective permeability by stating that sodium ions must travel through ion channels to enter the cell. This demonstrates that the cell membrane allows certain substances to pass through while blocking others. Receptors on the cell's surface (A) and cell communication (B) are related to cell function but do not directly confirm selective permeability. Environmental changes affecting cell size (C) are more about cell response than membrane permeability. In summary, choice D is correct because it directly addresses the concept of selective permeability, while the other choices do not provide direct evidence of this property.
Question 5 of 5
What is the temperature of 35�C in Kelvin?
Correct Answer: C
Rationale: Failed to generate a rationale after 5 retries.
