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?
Lactated Ringers (LR).
0.45% Sodium Chloride.
Dextrose in Lactated Ringers.
None of the above.
The Correct Answer is A
Choice A rationale
Lactated Ringers (LR) is an isotonic solution, which means it has the same osmolarity as blood plasma. This property makes LR suitable for rehydrating patients without causing a significant shift of fluids between compartments, maintaining the balance of electrolytes.
Choice B rationale
0.45% Sodium Chloride is a hypotonic solution, meaning it has a lower osmolarity compared to blood plasma. This type of solution would cause fluid to move into cells, potentially leading to cellular swelling.
Choice C rationale
Dextrose in Lactated Ringers is a hypertonic solution because the added dextrose increases the osmolarity. This solution can cause fluid to shift out of cells, leading to cellular shrinkage, which is not ideal for rehydration.
Choice D rationale
None of the above is incorrect because Lactated Ringers (LR) is indeed an isotonic solution.
