ATI Fluid Electrolyte and Acid-Base Regulation

1. A nurse is caring for a client who is having a subclavian central venous catheter inserted. The client begins to report chest pain and difficulty breathing. After administering oxygen, which action should the nurse take next?

Correct answer: B

Rationale:

2. The nurse in the intensive care unit receives arterial blood gases (ABG) with a patient who is complaining of being 'short of breath.' The ABG has the following values: pH = 7.21, PaCO2 = 64 mm Hg, HCO3 = 24 mmol/L. The labs reflect:

Correct answer: A

Rationale: The ABG values indicate respiratory acidosis. A pH below 7.40, a PaCO2 above 40 mm Hg, and a normal HCO3 level (24 mmol/L) suggest respiratory acidosis. In this case, the patient has an acidic pH (7.21) and an elevated PaCO2 (64 mm Hg), indicating inadequate ventilation. The normal HCO3 level suggests that compensation by the kidneys has not occurred, implying an acute event. Choices B, C, and D can be ruled out based on the given ABG values and the criteria for acid-base disorders.

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?

Correct answer: B

Rationale:

4. The renin and angiotensin systems help to maintain the balance of sodium and water in the body. What other functions do these systems serve?

Correct answer: B

Rationale: The correct answer is B: Maintaining a healthy blood volume. The renin and angiotensin systems not only help to regulate sodium and water balance in the body but also play a crucial role in maintaining an adequate blood volume. This is essential for normal blood pressure regulation and overall cardiovascular health. Choices A, C, and D are incorrect because hemoglobin levels are primarily regulated by the bone marrow and erythropoietin, platelets are released in response to blood vessel injury by a different mechanism, and the systems do not focus on lowering blood volumes but rather on maintaining them.

5. A nurse is caring for an older adult client who is admitted with moderate dehydration. Which intervention should the nurse implement to prevent injury while in the hospital?

Correct answer: D

Rationale: The correct answer is to 'dangle the client on the bedside before ambulating.' This intervention helps prevent orthostatic hypotension, a drop in blood pressure when changing positions, which is crucial in preventing falls and related injuries in older adult clients. Asking family members to speak quietly (Choice A) may help keep the client calm but does not directly address the risk of injury. Assessing urine parameters (Choice B) is important for monitoring hydration status but does not specifically prevent injury. Encouraging increased fluid intake (Choice C) is essential for managing dehydration but does not directly address the risk of injury during ambulation.

You are working on a burns unit, and one of your acutely ill patients is exhibiting signs and symptoms of third spacing. Based on this change in status, you should expect the patient to exhibit signs and symptoms of what imbalance?
How would a decrease in blood protein concentration impact the fluid volumes?
Third spacing occurs when fluid moves out of the intravascular space but not into the intracellular space. Based on this fluid shift, the nurse will expect the patient to demonstrate:
