Question 1 of 5

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?

A. Lactated Ringers (LR). B. 0.45% Sodium Chloride. C. Dextrose in Lactated Ringers. D. None of the above.

Correct Answer: A

Rationale: The correct answer is A: Lactated Ringers (LR) is considered an isotonic solution. LR has an osmolarity close to that of blood plasma, making it isotonic. This means it will not cause fluid shifts across cell membranes.
Choice B, 0.45% Sodium Chloride, is hypotonic and could cause cellular swelling.
Choice C, Dextrose in Lactated Ringers, is hypertonic due to the added dextrose.
Choice D, None of the above, is incorrect as LR is indeed an isotonic solution.
