Chapter 14 Nutrition and Fluid Balance Workbook Answers Questions
Question 1 of 5
Which of these conditions could be a cause of respiratory acidosis?
Correct Answer: D
Rationale: Respiratory acidosis occurs when the lungs can't remove enough carbon dioxide, leading to an increase in blood acidity. Emphysema, choice D, a lung condition causing poor air exchange, can result in respiratory acidosis. Aspirin poisoning (choice A) typically causes metabolic acidosis. Severe vomiting (choice B) can lead to metabolic alkalosis due to loss of stomach acid. Severe diarrhea (choice C) can also cause metabolic acidosis from loss of bicarbonate. Therefore, the correct answer is D as it directly affects the respiratory system and can lead to respiratory acidosis.
Question 2 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 3 of 5
Although the terms "water" and "fluid" are often used to refer to the same thing, they are actually different.
Correct Answer: A
Rationale: The correct answer is A: TRUE. Water and fluid are not interchangeable terms. Water specifically refers to the liquid state of H2O molecules, while fluid is a broader term encompassing any substance that flows and takes the shape of its container. Water is a type of fluid, but not all fluids are water. Therefore, it is accurate to say that water and fluid are different. Summary of Other Choices: B: FALSE - Incorrect because water and fluid have distinct meanings. C: NA - Not applicable as it does not provide a valid response. D: NA - Not applicable as it does not provide a valid response.
Question 4 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 5 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.
