ATI Fluid and Electrolytes

1. Which mineral is important in hemoglobin production?

Correct answer: C

Rationale: Iron (Fe) is a critical mineral in hemoglobin production. Hemoglobin is a protein found in red blood cells that is essential for transporting oxygen throughout the body. Sodium (Choice A), Iodine (Choice B), and Chloride (Choice D) are not directly involved in hemoglobin production. Sodium is an electrolyte that helps maintain fluid balance, Iodine is essential for thyroid hormone production, and Chloride is an electrolyte that helps regulate fluid balance and acidity in the body.

2. A patient with hypokalemia and heart failure is admitted to the telemetry unit. The nurse is aware that hypokalemia could cause which of the following abnormalities on an electrocardiogram (ECG)?

Correct answer: D

Rationale: The correct answer is D: Elevated U wave. Hypokalemia is associated with ECG changes such as an elevated U wave and flattened T waves. Choice A, a shortened P-R interval, is not typically seen in hypokalemia. Choice B, an inverted T wave, is more commonly associated with ischemia or CNS injury rather than hypokalemia. Choice C, a depressed U wave, is not a typical ECG abnormality seen in hypokalemia. Therefore, the correct ECG abnormality associated with hypokalemia is an elevated U wave.

3. A nurse is caring for a patient who requires measurement of specific gravity every 4 hours. What does this test detect?

Correct answer: D

Rationale: Specific gravity is a test used to determine the concentration of solutes in the urine, reflecting the kidney's ability to concentrate urine. Changes in specific gravity can indicate fluid volume status, such as dehydration (fluid volume deficit) or overhydration (fluid volume excess). Options A, B, and C are incorrect as specific gravity does not directly detect nutritional deficits, hyperkalemia, or hypercalcemia.

4. Which of the following organs does not contribute to fluid output from the body?

Correct answer: D

Rationale: The correct answer is D. All the listed organs (lungs, skin, and intestines) contribute to fluid loss from the body. Lungs contribute to fluid loss through respiration, skin through sweating, and intestines through excretion. Therefore, none of the organs listed in the options retain fluids within the body. Choices A, B, and C are incorrect because all of these organs play a role in fluid output from the body.

5. You are an emergency-room nurse caring for a trauma patient. Your patient has the following arterial blood gas results: pH 7.26, PaCO2 28, HCO3 11 mEq/L. How would you interpret these results?

Correct answer: D
