ATI Fluid and Electrolytes
1. What is the fluid inside the cell called?
- A. Plasma
- B. Intracellular fluid
- C. Interstitial fluid
- D. Plasma and intracellular fluid
Correct answer: B
Rationale: The correct answer is 'Intracellular fluid.' Intracellular fluid refers to the fluid contained within the cells, constituting a significant portion of the body's total water content. Choices A, C, and D are incorrect. Plasma is the liquid component of blood outside the cells, interstitial fluid is the fluid surrounding cells in tissues, and the combination of plasma and intracellular fluid is not the specific term for the fluid inside the cell.
2. What is the main water-holding force in the blood capillaries?
- A. Capillary blood pressure
- B. Sodium in the blood plasma
- C. Protein in the blood plasma
- D. Chloride in the blood plasma
Correct answer: C
Rationale: The correct answer is C: Protein in the blood plasma. Plasma proteins, especially albumin, create oncotic pressure, which is the main force responsible for holding water within the blood capillaries. Capillary blood pressure (Choice A) is involved in pushing blood through the capillaries, while sodium and chloride in the blood plasma (Choices B and D) are electrolytes and do not play a significant role in the water-holding force within capillaries.
3. . A medical nurse educator is reviewing a patients recent episode of metabolic acidosis with members of the nursing staff. What should the educator describe about the role of the kidneys in metabolic acidosis?
- A. The kidneys retain hydrogen ions and excrete bicarbonate ions to help restore balance.
- B. The kidneys excrete hydrogen ions and conserve bicarbonate ions to help restore balance
- C. The kidneys react rapidly to compensate for imbalances in the body
- D. The kidneys regulate the bicarbonate level in the intracellular fluid.
Correct answer: B
Rationale:
4. . You are caring for a patient who has a diagnosis of syndrome of inappropriate antidiuretic hormone secretion (SIADH). Your patients plan of care includes assessment of specific gravity every 4 hours. The results of this test will allow the nurse to as
- A. Nutritional status
- B. Potassium balance
- C. Calcium balance
- D. Fluid volume status
Correct answer: D
Rationale:
5. What fluid is found in spaces between the cells?
- A. Intracellular fluid
- B. Interstitial fluid
- C. Plasma
- D. Electrolyte
Correct answer: B
Rationale: The correct answer is B, Interstitial fluid. Interstitial fluid is the fluid that surrounds and occupies the spaces between cells, providing them with nutrients and removing waste. Choices A, C, and D are incorrect because intracellular fluid refers to fluid inside cells, plasma refers to the liquid component of blood, and electrolyte refers to substances that dissociate into ions in solution, affecting fluid balance but not specifically found in spaces between cells.
