ATI Fluid Electrolyte and Acid-Base Regulation Questions
Question 1 of 5
A nurse develops a plan of care for a client who has a history of hypocalcemia. What interventions should the nurse include in this clients care plan? (Select all that apply.)
Correct Answer: B
Rationale: The correct answer is B. Straining all urine output and assessing for urinary stones is important for a client with hypocalcemia as they are at risk for developing kidney stones due to increased calcium excretion. By straining urine, the nurse can monitor for the presence of stones. A, using a draw sheet to reposition the client, is not directly related to hypocalcemia. C, providing nonslip footwear, is important for fall prevention but not specific to hypocalcemia. D, since it is not provided, cannot be evaluated.
Question 2 of 5
A nurse assesses a client who is experiencing an acid-base imbalance. The clients arterial blood gas values are pH 7.34, PaO2 88 mm Hg, PaCO2 38 mm Hg, and HCO3 19 mEq/L. Which assessment should the nurse perform first?
Correct Answer: A
Rationale: The correct answer is A: Cardiac rate and rhythm. In an acid-base imbalance, the pH is below the normal range indicating acidosis. The nurse should assess the cardiac rate and rhythm first because acidosis can have negative effects on the cardiovascular system. Acidosis can lead to arrhythmias and decreased cardiac output. Monitoring the cardiac rate and rhythm is crucial to detect any cardiac complications early. Choices B, C, and D are not the priority in this situation as they are not directly impacted by acid-base imbalances.
Question 3 of 5
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?
Correct Answer: D
Rationale: The correct answer is D: Metabolic alkalosis. Furosemide, a loop diuretic, can lead to potassium depletion and metabolic alkalosis due to excessive loss of chloride and hydrogen ions. The nurse should assess for signs of metabolic alkalosis such as confusion, muscle weakness, and dysrhythmias to prevent complications. Respiratory acidosis and alkalosis are not directly related to furosemide therapy. Metabolic acidosis is less likely due to furosemide's mechanism of action.
Question 4 of 5
A nurse is caring for a client who is experiencing moderate metabolic alkalosis. Which action should the nurse take?
Correct Answer: D
Rationale: The correct answer is D: Teach the client fall prevention measures. In metabolic alkalosis, the client may experience muscle weakness and confusion, increasing the risk of falls. Teaching fall prevention measures is essential to ensure the client's safety. Monitoring hemoglobin and hematocrit values (A) is not directly related to managing metabolic alkalosis. Administering furosemide (B) is not appropriate for metabolic alkalosis. Encouraging deep breaths (C) may not address the underlying cause of the alkalosis.
Question 5 of 5
A nurse is assessing a client who has acute pancreatitis and is at risk for an acid-base imbalance. For which manifestation of this acid-base imbalance should the nurse assess?
Correct Answer: B
Rationale: The correct answer is B: Kussmaul respirations. In acute pancreatitis, metabolic acidosis can occur due to the release of pancreatic enzymes. Kussmaul respirations are deep, rapid breaths that help to blow off excess carbon dioxide in response to acidosis, aiming to correct the pH imbalance. Agitation (A) is a nonspecific symptom and not specific to acid-base imbalances. Seizures (C) are more commonly associated with electrolyte imbalances such as hyponatremia or hypocalcemia. Positive Chvostek's sign (D) is a clinical sign of hypocalcemia, not directly related to acid-base imbalances in acute pancreatitis.
