Quiz on Hyponatremia & Hypernatremia Electrolytes

1. A patient has a sodium level of 123 and presents with confusion. The doctor diagnoses the patient with Syndrome of Inappropriate Antidiuretic Hormone Secretion (SIADH). Which type of hyponatremia is this?
A. Hypovolemic

The answer is B: Euvolemic

2. A patient with a sodium level of 112 is taking Lithium. Which of the following is a nursing priority?
A. Hold further doses of Lithium
B. Monitor Lithium drug level due to risk of toxicity
C. Monitor potassium level due to increased risk of toxicity
D. No priority is need. 112 is a normal sodium level

3. A patient with a sodium level of 178 is ordered to be started on 0.45% Saline. What is the most IMPORTANT nursing intervention for this patient?
A. Maintain patent IV
B. Give rapidly to ensure fluids levels are shifted properly
C. Clarify doctor’s order because 0.45% saline is contraindicated in hypernatremia
D. Give slowly and watch for signs and symptoms of cerebral edema
The answer is D: Give slowly and watch for signs and symptoms of cerebral edema. The most important intervention is to give slowly and watch for S&S of cerebral edema because a hypotonic solution can cause rapid swelling of the cell. Maintain a patent IV is correct but not the most important option in this scenario.
