ATI Fluid Electrolyte and Acid-Base Regulation Questions

Question 1 of 5

A nurse is caring for clients with electrolyte imbalances on a medical-surgical unit. Which clinical manifestations are correctly paired with the contributing electrolyte imbalance? (Select all that do not apply.)

Correct Answer: B

Rationale: The correct answer is B because hyperphosphatemia can lead to paresthesia with sensations of tingling and numbness due to its effect on nerve function. A, hypokalemia causes muscle weakness but not flaccid paralysis with respiratory depression. C, hyponatremia typically presents with symptoms such as confusion and seizures, not decreased level of consciousness.

Question 2 of 5

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?

Correct Answer: B

Rationale: The correct answer is B: Place warm compresses on the site. Warm compresses can help increase blood flow, reduce pain, and promote healing at the site of inflammation. The warmth can help dilate blood vessels, increasing circulation to the area and promoting the removal of inflammatory substances. This can help alleviate pain and reduce swelling. Administering topical lidocaine (choice A) may not address the underlying cause of pain and redness. Administering oral pain medication (choice C) may be necessary for severe pain but may not directly address the local inflammation. Massaging the site with scented oils (choice D) can potentially introduce more irritants and should be avoided in cases of inflammation.

Question 3 of 5

While assessing clients on a medical-surgical unit, which client is at risk for hypokalemia?

Correct Answer: A

Rationale: The correct answer is A: Client with pancreatitis who has continuous nasogastric suctioning. Pancreatitis can lead to gastrointestinal losses of potassium, and continuous nasogastric suctioning can further exacerbate this potassium loss, putting the client at risk for hypokalemia. The other choices are incorrect because: B: ACE inhibitors can cause hyperkalemia, not hypokalemia. C: Blood transfusions can lead to hyperkalemia due to the potassium content in blood products. D: Uncontrolled diabetes and a serum pH level of 7.33 are not directly associated with hypokalemia.

Question 4 of 5

.A nurse assesses a clients peripheral IV site, and notices edema and tenderness above the site. Which action should the nurse take next?

Correct Answer: D

Rationale: The correct action is to stop the infusion of intravenous fluids. Edema and tenderness above the IV site suggest infiltration, where fluid leaks into surrounding tissues. Stopping the infusion prevents further damage and helps prevent complications. Applying cold compresses (A) may not address the underlying issue. Elevating the extremity (B) is helpful for other conditions like swelling due to dependent edema, not infiltration. Flushing the catheter (C) can exacerbate the issue by pushing more fluid into the tissue.

Question 5 of 5

A nurse is caring for a client who is experiencing excessive diarrhea. The clients arterial blood gas values are pH 7.28, PaO2 98 mm Hg, PaCO2 45 mm Hg, and HCO3 16 mEq/L. Which provider order should the nurse expect to receive?

Correct Answer: B

Rationale: The correct answer is B: Sodium bicarbonate 100 mEq diluted in 1 L of D5W. In this case, the client is experiencing metabolic acidosis due to low HCO3 levels (16 mEq/L) with a low pH (7.28). Sodium bicarbonate helps correct metabolic acidosis by increasing the HCO3 levels. Furosemide (A) is a diuretic and can worsen the client's electrolyte imbalance. Mechanical ventilation (C) is not indicated for metabolic acidosis. Indwelling urinary catheter (D) does not address the underlying acid-base imbalance. Therefore, the nurse should expect the provider to order sodium bicarbonate to correct the metabolic acidosis.
