1. Which of the following terms describes the amount of blood ejected per heartbeat?

• A. Stroke volume
• B. Cardiac output
• C. Ejection fraction
• D. Afterload

Correct answer: A

Rationale: The correct answer is A: Stroke volume. Stroke volume refers to the amount of blood ejected by the left ventricle in one contraction. Choice B, Cardiac output, is the total volume of blood pumped by the heart per minute and is calculated by multiplying stroke volume by heart rate. Choice C, Ejection fraction, is the percentage of blood pumped out of the left ventricle with each heartbeat. Choice D, Afterload, refers to the pressure or resistance that the ventricles must overcome to eject blood during systole. Therefore, in the context of the question, the term that specifically describes the amount of blood ejected per heartbeat is stroke volume.

2. 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?

• A. Increase intake of dairy products, including yogurt and ice cream
• B. Maintain an upright position while eating
• C. Opt for foods that are high in fiber
• D. Consume small, frequent meals when hunger strikes

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.

3. Which foods should be avoided on a low-potassium diet? (SATA)

• A. Bananas

• C. Sweet potatoes
• D. Frozen corn

Correct answer: B

4. Which statement indicates understanding of a low-fiber diet?

• A. I can cut up carrots and celery sticks for my lunch.
• B. I will eat a bran muffin for my mid-morning snack.
• C. I will have oatmeal with skim milk for my breakfast.
• D. I should choose canned peaches for my fruit serving.

Correct answer: D

Rationale: The correct answer is D because canned peaches are low in fiber compared to the other options provided. Option A contains high-fiber vegetables (carrots and celery), option B includes a bran muffin which is fiber-rich, and option C involves oatmeal which is also a good source of fiber. Therefore, choosing canned peaches aligns with a low-fiber diet.

5. Digestible carbs are absorbed as ___ through the small intestinal wall and are delivered to the liver, which releases ___ into the bloodstream.

• A. glucose

Rationale: Digestible carbohydrates are absorbed as monosaccharides (simple sugars) like glucose, which the liver can release into the bloodstream for energy.
