Medical Surgical Phosphate #4

Question

Which of these are major causes of hypophosphatemia? Select all that apply.

Answers

  1. Antacids
    • Rationale:

      This answer is correct because calcium is a component of antacids and causes phosphorus to decrease. As calcium rises in the blood, phosphate levels fall and visa versa.

  2. Heat stroke
    • Rationale:

      This answer is correct because having a heat stroke depletes fluids from the body causing a decrease in phosphorus. Low phosphorus levels caused from a heat stroke affects the client’s mental status, but once phosphorus is restored, the client normally becomes alert and oriented.

  3. Low potassium
    • Rationale:

      This answer is correct because low potassium levels can deplete phosphorus levels. Phosphorus is eliminated with potassium and leaves the body with potassium.

  4. Low calcium
    • Rationale:

      This answer is not correct because calcium and phosphorus have an inverse relationship. When phosphorus is low, calcium is high. When calcium is high, phosphorus is low.

  5. Hepatic encephalopathy
    • Rationale:

      This answer is correct because with hepatic encephalopathy, the client has an increased ammonia level, which depletes phosphate. Clients with acute or chronic liver problems have a decreased phosphate level as well.

Overview

The major causes of hypophosphatemia include antacids, heat stroke, low potassium, and hepatic encephalopathy. Hypophosphatemia is an electrolyte imbalance resulting from low levels of phosphate.

Explanation

Learning Outcomes

The major causes of hypophosphatemia include antacids, alcohol withdrawal, thermal burns, heat stroke, low potassium, low magnesium, and hepatic encephalopathy. Hypophosphatemia levels are less than 3.0 mg/dl. Symptoms of hypophosphatemia include loss of appetite, irritability, confusion, weakness, and trouble breathing.
