Chapter 14 Nutrition and Fluid Balance Workbook Answers Questions
Question 1 of 5
When the ingestion and metabolic synthesis of a substance equals its metabolic utilization and excretion, the body is
Correct Answer: A
Rationale: The correct answer is A. When the ingestion and metabolic synthesis of a substance equal its metabolic utilization and excretion, the body is in a state of balance, known as homeostasis. This means that the body is efficiently utilizing and eliminating the substance to maintain equilibrium. Option B is incorrect because in this scenario, the body is indeed in balance, not in imbalance. Options C and D are also incorrect as they do not provide any relevant information or reasoning. In summary, the correct answer (A) reflects a state of equilibrium in the body's metabolic processes, while the other choices do not accurately describe the situation.
Question 2 of 5
Proteins within the ICF are not freely exchanged with the ECF.
Correct Answer: A
Rationale: The correct answer is A: TRUE. Proteins within the intracellular fluid (ICF) are not freely exchanged with the extracellular fluid (ECF) due to the presence of the cell membrane. The cell membrane acts as a semi-permeable barrier that selectively regulates the movement of substances in and out of the cell. Proteins are too large to pass through the cell membrane freely, thus preventing their exchange between the ICF and ECF. This selective permeability is crucial for maintaining the internal environment of the cell and supporting various cellular functions. Option B: FALSE is incorrect because the statement is indeed true, as explained above. Options C and D are not applicable as they do not provide any relevant information to address the question.
Question 3 of 5
Salt conservation by the body will result in a hypertonic ECF.
Correct Answer: A
Rationale: Certainly! Salt conservation by the body will lead to an increase in the sodium concentration in the extracellular fluid (ECF), making it hypertonic. This occurs when the kidneys reabsorb more sodium to maintain electrolyte balance. Other choices are incorrect as they do not accurately describe the outcome of salt conservation on ECF tonicity.
Question 4 of 5
Water balance can be regulated independently from solute regulation.
Correct Answer: A
Rationale: Water balance can be regulated independently from solute regulation because the body has separate mechanisms to control water and solute levels. The kidneys regulate water balance through processes like reabsorption and excretion, while solute regulation involves maintaining proper concentrations of ions and molecules in the body. Therefore, it is true that water balance can be controlled independently from solute regulation. Other choices are not applicable (NA) as they do not provide relevant information on the question.
Question 5 of 5
Diabetes insipidus often leads to hypertonicity of the body fluids.
Correct Answer: A
Rationale: Diabetes insipidus causes excessive urination leading to dehydration and increased concentration of body fluids. This results in hypertonicity, making choice A true. Choice B is incorrect as it contradicts the physiological response to diabetes insipidus. Choices C and D are not applicable as they do not provide any relevant information.
