ATI Nutrition Practice A Questions

Question 1 of 5

What is the first step in the scientific method?

Correct Answer: B

Rationale: The first step in the scientific method is to make an observation and ask a question. This is because the scientific method is a systematic process of investigation that begins with observing a phenomenon or asking a question about it. This is followed by formulating a hypothesis (Choice C), designing and conducting an experiment to test the hypothesis (Choice A), and analyzing the results to reach a consensus or conclusion (Choice D). Therefore, choices A, C, and D are incorrect as they represent steps that occur after the initial observation and question.

Question 2 of 5

Which strategy would most likely help alleviate some of the nausea that a 10-week pregnant woman experiences every morning, preventing her from eating breakfast?

Correct Answer: D

Rationale: The correct answer is D, 'Consume small, frequent meals when hunger strikes.' This strategy is ideal for managing morning sickness because it prevents the stomach from becoming too empty, which can exacerbate nausea. Option A may not be helpful because dairy products can sometimes worsen nausea. Option B is not the most effective solution as the sitting position does not directly impact nausea levels. Option C, while generally beneficial for digestion and overall health, does not specifically address the issue of pregnancy-related nausea.

Question 3 of 5

Which organ absorbs water and vitamin K and may be affected by ulcerative colitis?

Correct Answer: C

Rationale: The large intestine is the organ that is primarily responsible for the absorption of water and vitamin K in the human body. A disease like ulcerative colitis can disrupt these functions by causing inflammation and ulcers in the lining of the large intestine, leading to digestive issues. The stomach (Choice A) primarily functions to break down and digest food, not to absorb water and vitamins. The pancreas (Choice B) secretes enzymes to aid in digestion and hormones to regulate blood sugar, but does not absorb water and vitamins. The small intestine (Choice D) is primarily responsible for absorbing nutrients from digested food, but not specifically water and vitamin K. Therefore, these other choices are incorrect.

Question 4 of 5

Weight loss therapies that rely on juicing typically provide increased fiber, vitamins, and minerals. As an added incentive, juices contain a lower concentration of sugar than the whole fruit. Are these statements true or false?

Correct Answer: B

Rationale: The correct answer is both statements are false. The process of juicing often extracts the liquid components of fruits and vegetables, leaving behind the fiber-rich pulp. Therefore, juicing does not typically provide increased fiber. Additionally, juices can contain a higher concentration of sugar than whole fruits because the fiber, which helps to slow down the absorption of sugar, has been removed. This can lead to a spike in blood sugar levels after consumption. The other options are incorrect because they contain at least one false statement.

Question 5 of 5

Begins carb digestion in the mouth:

Correct Answer: B

Rationale: Salivary amylase is the enzyme that begins the digestion of carbohydrates in the mouth by breaking down starches into simpler sugars.
