The nurse is preparing to administer hydration via an intravenous route to a client. The nurse understands that the patient needs an isotonic solution. Which of the following options is considered an isotonic solution?
Correct answer
A
Rationale
The correct answer is A: 0.9% Sodium Chloride. This solution is isotonic because it has the same osmolarity as normal blood plasma. It helps maintain fluid balance without causing cells to shrink or swell. Choice B, 0.45% Sodium Chloride, is hypotonic and could cause cells to swell. Choice C, 5% Dextrose in Lactated Ringers, is hypertonic due to the high concentration of dextrose. Choice D is incorrect as 0.9% Sodium Chloride is indeed an isotonic solution.
