Fluid and Electrolytes NCLEX RN Questions Questions
Question 1 of 5
The nurse interprets this ABG result as Laboratory: pH 7.62 [7.35-7.45], PaCO2 19 mmHg [35-45 mm Hg], HCO3- 24 mEq/L [22-28 mEq/L], PaO2 85 mmHg [80-100 mm Hg]
Correct Answer: D
Rationale: High pH (7.62) and low PaCO2 (19 mm Hg) with normal HCO3- indicate uncompensated respiratory alkalosis (
D) due to hyperventilation.
Question 2 of 5
The nurse should interpret these results to indicate that the client has Laboratory: pH 7.50 [7.35-7.45], PaCO2 28 mmHg [35-45 mm Hg], HCO3- 25 mEq/L [22-28 mEq/L]
Correct Answer: C
Rationale: High pH (7.50) and low PaCO2 (28 mm Hg) with normal HCO3- indicate respiratory alkalosis (
C) due to hyperventilation.
Question 3 of 5
The nurse in the emergency department (ED) is caring for a client with dyspnea and coughing up purulent sputum. The nurse reviews the arterial blood gas (ABG) results: pH 7.25 [7.35-7.45], PaO2 93 mmHg [80-100 mmHg], PaCO2 69 mmHg [35-45 mm Hg], HCO3 25 mmol/L [22-28 mEq/L]. The nurse should interpret these results to indicate that the client has
Correct Answer: B
Rationale: The ABG shows low pH (7.25) and high PaCO2 (69 mm Hg), indicating respiratory acidosis (
B) due to CO2 retention, likely from impaired ventilation due to pneumonia.
Question 4 of 5
The nurse should recognize that the client is experiencing Laboratory: pH 7.19 [7.35-7.45], PaCO2 36 mm Hg [35-45 mm Hg], HCO3 12 mEq/L [22-28 mEq/L], PaO2 90 mm Hg [80-100 mm Hg]
Correct Answer: B
Rationale: Low pH (7.19) and low HCO3- (12 mEq/L) with normal PaCO2 indicate uncompensated metabolic acidosis (
B). No compensation is evident as PaCO2 is normal.
Question 5 of 5
The nurse should interpret these results to indicate that the client has? Laboratory: pH 7.30 [7.35-7.45], PaCO2 50 mmHg [35-45 mm Hg], HCO3- 24 mEq/L [22-28 mEq/L]
Correct Answer: A
Rationale: Low pH (7.30) and high PaCO2 (50 mm Hg) with normal HCO3- indicate uncompensated respiratory acidosis (
A).
