Medical Surgical Potassium K+ #12

Question

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

Answers

  1. Calcium
    • Rationale:

      This answer is not correct because acute renal failure is less likely to affect the calcium levels in comparison to the impact this condition has on serum potassium levels within the body.

  2. Potassium
    • Rationale:

      This answer is correct because potassium is the electrolyte that is most likely to be impacted by acute renal failure; therefore, the nurse monitors the client for symptoms of hyperkalemia.

  3. Magnesium
    • Rationale:

      This answer is not correct because acute renal failure is less likely to affect the magnesium levels in comparison to the impact this condition has on serum potassium levels within the body.

  4. Phosphorus
    • Rationale:

      This answer is not correct because acute renal failure is less likely to affect the phosphorus levels in comparison to the impact this condition has on serum potassium levels within the body.

Overview

Acute renal failure occurs when the kidneys suddenly become unable to filter waste products from the blood. Acute renal failure develops rapidly over a few hours or days.

Explanation

Learning Outcomes

Acute renal failure develops rapidly over a few hours or days. Clinical manifestations include decreased urinary output, edema due to fluid retention, nausea, fatigue, and dyspnea. Acute renal failure increases the likelihood of fluid and electrolyte imbalances within the body. With acute renal failure, the kidneys are unable to continuously remove excess potassium, which can lead to hyperkalemia; therefore, the nurse monitors the client for this electrolyte imbalance.

Test Taking Tip

Consider the function of the kidneys in relation to electrolytes to answer this question correctly.
