Electrolytes Question #60


The nurse is caring for a client with acute renal failure. For which electrolyte will the nurse monitor for an imbalance?


  1. Potassium
    • Rationale:
  2. Magnesium
    • Rationale:
  3. Phosphorus
    • Rationale:
  4. Calcium
    • Rationale:



The correct answer is A. With acute renal failure, the kidneys are unable to continuously remove excess potassium, which can lead to hyperkalemia. Acute renal failure is less likely to affect the magnesium, phosphorus, and calcium levels.

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.
