Nutrition and Fluid Balance Chapter 14 Questions
Question 1 of 5
The only way for substances to be removed from the internal pool is by excreting them from the body.
Correct Answer: B
Rationale: Step 1: The internal pool includes various substances like nutrients, waste products, and ions. Step 2: Substances can also be removed through metabolic processes like oxidation or conversion. Step 3: Excretion is not the sole method; other ways include sweat, breath, or shedding skin. Step 4: Therefore, the statement that excretion is the only way for substances to be removed from the internal pool is false.
Question 2 of 5
Synovial fluid is a type of transcellular fluid that surrounds the joints.
Correct Answer: A
Rationale: 1. Synovial fluid is a type of transcellular fluid that surrounds the joints - TRUE. 2. Synovial fluid is a clear, viscous fluid found in the cavities of synovial joints. 3. It provides lubrication, nourishment, and shock absorption to the joints. 4. It is produced by the synovial membrane and helps reduce friction between the joint surfaces. 5. Therefore, the statement is accurate, making choice A the correct answer.
Question 3 of 5
All fluid that enters or leaves the ICF must pass through the ECF.
Correct Answer: B
Rationale: Step 1: The ICF (Intracellular Fluid) is the fluid inside the cells, and the ECF (Extracellular Fluid) is the fluid outside the cells. Step 2: Not all fluid that enters or leaves the ICF must pass through the ECF. There are mechanisms such as osmosis and active transport that allow for direct movement of fluid in and out of the cells. Step 3: Therefore, it is not true that all fluid entering or leaving the ICF must pass through the ECF, making the correct answer B: FALSE. Summary: Choice A is incorrect because it wrongly states that all fluid must pass through the ECF. Choices C and D are not applicable as they do not provide any relevant information.
Question 4 of 5
Obligatory losses represent the amount of sodium that normally needs to be replenished in the body in order to
Correct Answer: B
Rationale: The correct answer is B: FALSE. Obligatory losses do not represent the amount of sodium that needs to be replenished in the body. Instead, they refer to the minimum amount of sodium that the body must excrete daily to maintain proper sodium balance. Replenishing sodium is not the purpose of obligatory losses. Choice A is incorrect because obligatory losses do not indicate the amount of sodium that needs to be replenished. Choices C and D are not applicable as they are not valid answers to the question.
Question 5 of 5
The secretion of aldosterone promotes the reabsorption of sodium.
Correct Answer: A
Rationale: The correct answer is A: TRUE. Aldosterone, a hormone produced by the adrenal glands, plays a key role in regulating electrolyte and fluid balance in the body. It acts on the kidneys to increase the reabsorption of sodium, leading to increased water retention and higher blood pressure. This process helps maintain electrolyte balance and blood pressure levels within the body. Therefore, the secretion of aldosterone does promote the reabsorption of sodium. Choices B, C, and D are incorrect as they do not provide any relevant information or explanation related to the question.
