ATI Fluid and Electrolytes
1. 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.
2. Which negative ion is most important in intracellular fluid?
- A. Phosphate ions.
- B. Protein molecules.
- C. Chlorine.
- D. Phosphate ions and protein molecules.
Correct answer: D
Rationale: Intracellular fluid contains phosphate ions and protein molecules as essential anions. Phosphate ions play a crucial role in various cellular processes, including energy transfer. Proteins, being large molecules with negative charges, also contribute significantly to the negative ion concentration within cells. Chlorine is primarily an extracellular anion and is not as prominent as phosphate ions and proteins within intracellular fluid, making it a less important negative ion in this context. Therefore, the correct answer is D because both phosphate ions and protein molecules are crucial negative ions in intracellular fluid.
3. A client reports taking Aspirin about four times daily for a sprained wrist. Which of the following prescribed medications taken by the client is contraindicated with aspirin?
- A. Digoxin
- B. Metformin
- C. Warfarin
- D. Nitroglycerin
Correct answer: C
Rationale: The correct answer is C, Warfarin. Aspirin increases the effect of anticoagulants like warfarin by inhibiting platelet aggregation, leading to an increased risk of bleeding. Therefore, the use of aspirin is generally contraindicated for clients taking warfarin. Choices A, B, and D are not contraindicated with aspirin. Digoxin, Metformin, and Nitroglycerin do not have significant interactions with Aspirin, unlike Warfarin, making them safe to use concomitantly.
4. A client is 4 hours postoperative following abdominal surgery. The client's blood pressure has dropped from 120/80 mm Hg to 90/60 mm Hg. What action should the nurse take first?
- A. Administer an IV fluid bolus.
- B. Check the surgical site for bleeding.
- C. Place the client in a Trendelenburg position.
- D. Notify the healthcare provider.
Correct answer: B
Rationale: Checking the surgical site for bleeding is crucial in this situation as it helps determine if the drop in blood pressure is due to hemorrhage, a potential postoperative complication. Identifying and addressing bleeding promptly is essential to prevent further complications and stabilize the client's condition.
5. A client has a new prescription for folic acid and believes it's only for pregnant women. What statement should the nurse make?
- A. Folic acid is important only for pregnant women.
- B. You don’t need folic acid if you eat a balanced diet.
- C. Folic acid is important for the building of blood cells for adults and children.
- D. You should take folic acid only if your blood tests show a deficiency.
Correct answer: C
Rationale: The correct answer is C because folic acid is essential for the production of red blood cells in adults and children, not just for pregnant women. Option A is incorrect as folic acid is not exclusive to pregnant women. Option B is incorrect as a balanced diet may not provide sufficient folic acid. Option D is incorrect since folic acid supplementation is also recommended for other reasons beyond deficiency.
