A nurse is caring for a client who has hypernatremia and requires IV fluid therapy due to his NPO status. Which of the following solutions should the nurse prepare to infuse for this client?
Lactated Ringer's
0.45% sodium chloride
Dextrose 5% in 0.9% sodium chloride
Dextrose 10% in water
The Correct Answer is B
A. Lactated Ringer's is a balanced electrolyte solution, but it contains sodium in a similar concentration to normal serum levels. It is not appropriate for a client with hypernatremia, as it could further increase their sodium levels.
B. 0.45% sodium chloride, also known as half-normal saline, is a hypotonic solution with a lower concentration of sodium than normal serum levels. It can help to lower the sodium levels in a client with hypernatremia by diluting the excess sodium in the body.
C. Dextrose 5% in 0.9% sodium chloride is a hypertonic solution that contains both dextrose and sodium. It would not be appropriate for a client with hypernatremia, as it could exacerbate the condition.
D. Dextrose 10% in water is a hypertonic solution with a high concentration of dextrose.
It does not contain sodium, but it is still a hypertonic solution and not appropriate for a client with hypernatremia.
