A nurse is planning care for a client who has hypernatremia. Which of the following interventions should the nurse include in the plan?
A.
Administer hypotonic IV fluids.
B.
Monitor blood glucose levels.
C.
Provide oral care every 4 hours.
D.
Increase dietary intake of potassium.
The Correct answer and Explanation is:
The correct answer is A. Administer hypotonic IV fluids.
Explanation:
Hypernatremia is a condition in which the sodium concentration in the blood is abnormally high (greater than 145 mEq/L). It typically results from either a loss of free water in the body or an excessive intake of sodium. Hypernatremia can lead to cellular dehydration, as water shifts from the intracellular space to the extracellular space to balance the elevated sodium levels.
To correct hypernatremia, the focus is on restoring water balance and reducing the sodium concentration in the blood.
- Administer hypotonic IV fluids (A):
- Hypotonic solutions, such as 0.45% sodium chloride (half-normal saline) or 5% dextrose in water (D5W), help to hydrate the cells and decrease the sodium concentration in the blood by providing free water. These solutions move fluid from the extracellular space into the cells, reversing the cellular dehydration caused by hypernatremia.
- Administering hypotonic fluids is the first-line intervention in cases of severe hypernatremia, especially when the client cannot drink adequate amounts of water to correct the imbalance.
- Monitor blood glucose levels (B):
- Monitoring blood glucose levels is not directly related to managing hypernatremia unless the client has diabetes or is receiving dextrose-containing IV fluids, which could increase blood sugar. However, hypernatremia management itself does not typically involve glucose regulation.
- Provide oral care every 4 hours (C):
- While this intervention can help prevent dry mouth or mucosal irritation due to dehydration, it is not a primary treatment for hypernatremia. Oral care supports comfort but does not address the underlying fluid imbalance.
- Increase dietary intake of potassium (D):
- Increasing potassium intake is not a relevant intervention for hypernatremia. Hypernatremia is a sodium imbalance, not a potassium imbalance. Therefore, managing potassium levels will not correct hypernatremia.
In summary, the priority intervention for a client with hypernatremia is to administer hypotonic fluids to lower the sodium concentration and restore normal fluid balance.
