Q2. The doctor has ordered intravenous fluid with potassium for a patient admitted with gastroenteritis and dehydration. Before adding potassium to the intravenous fluid, the nurse should:

Assess the urinary output
Obtain arterial blood gases
Perform a dextrostick
Obtain a stool culture

Show answer and explanation

Answer: A. Assess the urinary output

58. Answer A is correct. During dehydration, the kidneys compensate for electrolyte imbalance by retaining potassium. The nurse should check for urinary output before adding potassium to the IV fluid. Answer B is incorrect because it measures respiratory compensation caused by dehydration. Answers C and D do not apply to the use of intravenous fluid with potassium; therefore, they are incorrect.
