Fluid and Electrolytes NCLEX RN Questions Questions

Extract:


Question 1 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.

The nurse is caring for a client with chronic obstructive pulmonary disease (COPD) who is currently receiving mechanical ventilation. After reviewing the client's arterial blood gas (ABG), the nurse identifies this ABG as Laboratory: pH 7.24 [7.35-7.45], PaCO2 48 mm Hg [35-45 mm Hg], HCO3 23 mEq/L [22-28 mEq/L], PaO2 90 mm Hg [80-100 mm Hg]
The nurse interprets this ABG result as Laboratory: pH 7.59 [7.35-7.45], PaCO2 30 mmHg [35-45 mm Hg], HCO3- 24 mEq/L [22-28 mEq/L], PaO2 85 mmHg [80-100 mm Hg]
Which of the following arterial blood gas (ABG) results would the nurse expect if the client's condition is left untreated?
What arterial blood gas (ABG) values suggest this? pH 7.30 [pH 7.35-7.45], CO2 38 [PCO2 35-45 mm Hg], HCO3 18 mEq/L [HCO3 22-28 mEq/L]; pH 7.48 [pH 7.35-7.45], CO2 31 [PCO2 35-45 mm Hg], HCO3 24 [HCO3 22-28 mEq/L]; pH 7.42 [pH 7.35-7.45], CO2 36 [PCO2 35-45 mm Hg], HCO3 24 [HCO3 22-28 mEq/L]; pH 7.30 [pH 7.35-7.45], CO2 52 [PCO2 35-45 mm Hg], HCO3 29 [HCO3 22-28 mEq/L]
The nurse cares for a client receiving mechanical ventilation and reviews the client's most recent arterial blood gas (ABG). The nurse communicates the result with the primary healthcare provider (PHCP) and should recommend a prescription for which medication? Laboratory: pH 7.33 [7.35-7.45], PaCO2 53 mm Hg [35-45 mm Hg], HCO3 24 mEq/L [22-28 mEq/L], PaO2 89 mm Hg [80-100 mm Hg]
