ATI Fluid and Electrolytes
1. Where is the largest volume of water in the body located?
- A. Plasma
- B. The fluid inside the cells
- C. Interstitial fluid
- D. Lymph
Correct answer: B
Rationale: The correct answer is B. The largest volume of water in the body is found inside the cells, known as intracellular fluid. This fluid makes up the majority of the body's total water content. Choices A, C, and D are incorrect because while plasma, interstitial fluid, and lymph are important components of the body's fluid compartments, they do not contain the largest volume of water in the body.
2. A nurse is assessing a client who has chronic heart failure. Which of the following findings indicates that the client is experiencing fluid overload?
- A. Increased urine output
- B. Bounding peripheral pulses
- C. Weight loss
- D. Decreased heart rate
Correct answer: B
Rationale: In clients with chronic heart failure, bounding peripheral pulses are a classic sign of fluid overload. This occurs due to increased volume in the arterial system, causing a forceful pulse. Increased urine output (Choice A) is often seen in clients with fluid volume deficit, not overload. Weight loss (Choice C) is also inconsistent with fluid overload as it suggests a fluid deficit. Decreased heart rate (Choice D) is more commonly associated with conditions like bradycardia, hypothyroidism, or the use of certain medications, but not specifically indicative of fluid overload in chronic heart failure.
3. The parent of a child newly diagnosed with lactose intolerance is being taught by the nurse. Which food items identified by the parent indicate an understanding of foods to avoid?
- A. Popcorn, seeds, and any foods containing nuts.
- B. Milk, cheese, ice cream, and puddings.
- C. Wheat, rye, barley, and commercially baked goods.
- D. Eggs, ham, bacon, and canned meats.
Correct answer: B
Rationale: The correct answer is B. Milk, cheese, ice cream, and puddings contain lactose, which individuals with lactose intolerance should avoid. Choices A, C, and D do not contain lactose and are not typically problematic for individuals with lactose intolerance.
4. A client has a new prescription for nitroglycerin. Which of the following adverse effects should the nurse instruct the client to report that can indicate the medication is effective?
- A. Headache
- B. Nausea
- C. Dizziness
- D. Dry mouth
Correct answer: A
Rationale: Headache is a common side effect of nitroglycerin due to its vasodilatory effects. It can indicate that the medication is working effectively by dilating blood vessels, improving blood flow, and reducing cardiac workload. Therefore, the client should report experiencing headaches as it may suggest the therapeutic action of nitroglycerin. Nausea, dizziness, and dry mouth are not typically associated with the therapeutic effects of nitroglycerin and should be reported as adverse effects that may necessitate medical attention.
5. You are the surgical nurse caring for a 65-year-old female patient who is postoperative day 1 following a thyroidectomy. During your shift assessment, the patient complains of tingling in her lips and fingers. She tells you that she has an intermittent spasm in her wrist and hand, and she exhibits increased muscle tone. What electrolyte imbalance should you first suspect?
- A. Hypophosphatemia
- B. Hypocalcemia
- C. Hypermagnesemia
- D. Hyperkalemia
Correct answer: B
Rationale: The symptoms described, including tingling in the lips and fingers, intermittent spasms, and increased muscle tone, are indicative of tetany, which is a common manifestation of hypocalcemia. Hypocalcemia can lead to neuromuscular irritability, causing symptoms such as paresthesias and muscle spasms. Hypophosphatemia primarily affects the central nervous system, resulting in seizures and coma. Hypermagnesemia typically presents with hypoactive reflexes and somnolence. Hyperkalemia can cause paresthesias and anxiety, but in this case, the patient's symptoms are more suggestive of hypocalcemia.
