1. What is the main force that pushes fluid in blood capillaries?

• A. Blood pressure.
• B. Sodium in the blood plasma.
• C. Sodium in the interstitial fluid.
• D. Protein in the blood plasma.

Correct answer: A

Rationale: The correct answer is A, blood pressure. Blood pressure is the primary force that pushes fluid out of the capillaries into the surrounding tissues. This pressure difference is essential for the exchange of nutrients, gases, and waste products between the blood and tissues. Choices B, C, and D are incorrect as they do not represent the primary force responsible for pushing fluid in blood capillaries.

2. Which of the following organs does not contribute to fluid output from the body?

• A. Lungs
• B. Skin
• C. Intestine
• D. Lungs, skin, and intestine

Correct answer: D

Rationale: The correct answer is D. All the listed organs (lungs, skin, and intestines) contribute to fluid loss from the body. Lungs contribute to fluid loss through respiration, skin through sweating, and intestines through excretion. Therefore, none of the organs listed in the options retain fluids within the body. Choices A, B, and C are incorrect because all of these organs play a role in fluid output from the body.

3. What can cause dehydration?

• A. Prolonged vomiting.
• B. Prolonged diarrhea.
• C. Too little fluid intake.
• D. Prolonged vomiting, diarrhea, and too little fluid intake.

Correct answer: D

Rationale: Dehydration can result from significant fluid loss due to vomiting, diarrhea, or inadequate fluid intake. Prolonged vomiting and diarrhea lead to excessive fluid loss from the body, contributing to dehydration. Similarly, not consuming enough fluids can also result in dehydration. Choice A and B are too specific as they only mention one cause each, while choice C is also correct but does not encompass all the potential causes of dehydration as mentioned in choice D.
