1. You are a researcher testing out the effects of a new food molecule—MEGA—on bone health. In order to know if it actually travels to bone cells in the body, you first need to find out if it gets absorbed in the bloodstream. You eat a food containing MEGA, and you measure the molecule in your urine and feces. You only detect MEGA in the feces. Was MEGA absorbed?

• A. No—absorbed compounds show up in urine, not feces
• B. Yes—absorbed compounds show up in feces, not urine
• C.
• D.

Correct answer: A

Rationale: If MEGA was only detected in feces and not in urine, it was not absorbed into the bloodstream. Absorbed compounds typically appear in urine after processing by the body. The correct answer is A because the presence of a compound in feces indicates that it was not absorbed by the body and passed through the digestive system. Choices B, C, and D are incorrect as they do not align with the process of absorption and excretion in the body.

2. What is the first step in the scientific method?

• A. Conduct an experiment
• B. Make an observation and ask a question
• C. Formulate a hypothesis
• D. Reach a consensus

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.

3. For patients with hypertension, which dietary change is most recommended?

• A. Increase salt intake
• B. Reduce fiber intake
• C. Increase potassium intake
• D. Reduce sugar intake

Correct answer: C

Rationale: Increasing potassium intake can help reduce blood pressure in hypertensive patients.

4. What is the function of the gallbladder?

• A. to store bile
• B. to produce bile
• C. to digest bile
• D. to modify bile to a liquid form

Correct answer: A

Rationale: The correct answer is A: "to store bile." The gallbladder acts as a reservoir for bile produced by the liver. It releases bile into the small intestine to aid in the digestion of fats. Choice B is incorrect because the liver produces bile, not the gallbladder. Choice C is incorrect as the gallbladder does not digest bile but stores and releases it for digestion. Choice D is incorrect because bile is already in liquid form; the gallbladder does not modify it to a liquid state.

5. Which nursing diagnosis has nutritional implications?

• A. impaired dentition
• B. disruption of gas exchange
• C. self-esteem disturbance
• D. sleep pattern disturbance

Correct answer: A

Rationale: Impaired dentition affects a patient's ability to chew and consume a variety of foods, leading to potential nutritional deficiencies and malnutrition.
