ATI Fluid Electrolyte and Acid-Base Regulation

1. 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

Rationale:

2. You are caring for a patient who has a diagnosis of syndrome of inappropriate antidiuretic hormone secretion (SIADH). Your patient's plan of care includes assessment of specific gravity every 4 hours. The results of this test will allow the nurse to assess what aspect of the patient's health?

Correct answer: D

Rationale: Assessing the specific gravity in a patient with SIADH helps the nurse evaluate the patient's fluid volume status. Specific gravity indicates the concentration of solutes in the urine and can detect if the patient has a fluid volume deficit or excess. Nutritional status, potassium balance, and calcium balance are not directly assessed through specific gravity testing. Nutritional status is typically evaluated through dietary intake and anthropometric measurements. Potassium balance is assessed through blood tests and ECG monitoring. Calcium balance is evaluated through blood tests and bone density scans. Therefore, the correct answer is assessing fluid volume status through specific gravity testing.

3. What happens first in dehydration?

Correct answer: C

Rationale: In dehydration, the body first draws fluid from the interstitial space to maintain blood volume, leading to a decrease in interstitial fluid volume. This is why choice C is correct. Choice A is incorrect because intracellular fluid is not the first to be affected. Choice B is also incorrect as plasma volume reduction typically occurs after interstitial fluid loss. Choice D is incorrect as dehydration impacts both interstitial and intracellular fluid volumes.

4. . 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?

Correct answer: B

Rationale:

5. A nurse teaches a client who is prescribed a central vascular access device. Which statement should the nurse include in this clients teaching?

Correct answer: C

Rationale:
