ATI Fluid Electrolyte and Acid-Base Regulation
1. A nurse is caring for a client with a peripheral vascular access device who is experiencing pain, redness, and swelling at the site. After removing the device, which action should the nurse take to relieve pain?
- A. Administer topical lidocaine to the site.
- B. Place warm compresses on the site.
- C. . Administer prescribed oral pain medication.
- D. Massage the site with scented oils.
Correct answer: B
Rationale:
2. A nurse is caring for a client who has the following laboratory results: potassium 3.4 mEq/L, magnesium 1.8 mEq/L, calcium 8.5 mEq/L, sodium 144 mEq/L. Which assessment should the nurse complete first?
- A. Assess the client's dietary intake of foods high in potassium.
- B. Assess the client's neuromuscular status.
- C. Assess the client's fluid intake and output.
- D. Read food labels to determine sodium content.
Correct answer: D
Rationale: The correct answer is to read food labels to determine sodium content. The client's sodium level is crucial to monitor as it is on the higher side (144 mEq/L), which can indicate hypernatremia. Excessive sodium intake can lead to fluid retention and other complications. Assessing dietary sodium intake can help the nurse and client make necessary adjustments to prevent further sodium imbalances. Choices A, B, and C are not the priority in this situation as the client's sodium level needs immediate attention to prevent potential complications.
3. When planning the care of a patient with a fluid imbalance, the nurse understands that in the human body, water and electrolytes move from the arterial capillary bed to the interstitial fluid. What causes this to occur?
- A. Active transport of hydrogen ions across the capillary walls
- B. Pressure of the blood in the renal capillaries
- C. Action of the dissolved particles contained in a unit of blood
- D. Hydrostatic pressure resulting from the pumping action of the heart
Correct answer: D
Rationale:
4. A nurse assesses a client who is prescribed furosemide (Lasix) for hypertension. For which acid-base imbalance should the nurse assess to prevent complications of this therapy?
- A. Respiratory acidosis
- B. Respiratory alkalosis
- C. Metabolic acidosis
- D. Metabolic alkalosis
Correct answer: D
Rationale:
5. The triage nurse notes upon assessment in the emergency room that the patient with anxiety is hyperventilating. The nurse is aware that hyperventilation is the most common cause of which acid-base imbalance?
- A. Respiratory acidosis
- B. Respiratory alkalosis
- C. Metabolic acidosis
- D. Metabolic alkalosis
Correct answer: B
Rationale: The correct answer is B: Respiratory alkalosis. Hyperventilation is the most common cause of acute respiratory alkalosis. When a patient hyperventilates due to anxiety or other causes, they blow off excessive carbon dioxide, leading to a decrease in PaCO2 and a rise in pH. Choices A, C, and D are incorrect because hyperventilation leads to a decrease in PaCO2, causing respiratory alkalosis, not respiratory acidosis, metabolic acidosis, or metabolic alkalosis.
