Electrolytes Question #46


A client who is prescribed bicarbonate for metabolic acidosis also takes a fluoroquinolone. For which interaction should the nurse monitor this client?


  1. Urine retention
    • Rationale:
  2. Abdominal discomfort
    • Rationale:
  3. Renal failure
    • Rationale:
  4. Increased risk of crystalluria
    • Rationale:



The correct answer is D. Bicarbonate may increase the risk of a renal disorder. The crystals indicate cystinuria, which places the client at risk for cystine calculi. Bicarbonate taken with a fluoroquinolone does not cause urinary retention, abdominal discomfort, or renal failure.

NCLEX TIP: Using critical thinking is recommended when reading priority questions. Recognizing key words in the answer choices will allow you to know how to choose the correct answer for the question. Go through each answer choice and decide is it: Maslow’s hierarchy, safety-related, or following the nursing process (ADPIE). Never complete a nursing action that is outside the scope of practice.
