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?
0.9% Sodium Chloride
0.45% Sodium Chloride
5% Dextrose in Lactated Ringers
None of the above
The Correct Answer is A
A. 0.9% Sodium chloride (normal saline) is an isotonic solution, meaning it has a similar osmolality to the blood and will not cause fluid shifts into or out of cells.
B. This is a hypotonic solution, which has a lower osmolality than blood and can cause water to move into cells, potentially leading to cell swelling.
C. This solution is considered isotonic, but it has dextrose, which is metabolized quickly in the body, potentially making the solution hypotonic after glucose is used.
D. This is incorrect, as 0.9% Sodium Chloride is an isotonic solution.

Correct Answer is B
Explanation
A. This is not the correct action because the issue with misoprostol in pregnancy is not related to the route of administration, but rather its potential to cause uterine contractions and harm to the pregnancy. The nurse should not administer the medication at all, regardless of the route, and should notify the physician for further clarification.
B. Misoprostol is contraindicated in pregnancy because it can cause uterine contractions, which may result in a miscarriage or preterm labor. The nurse should not administer this medication and must inform the healthcare provider to reconsider the prescription or explore alternative options to prevent stomach ulcers in pregnant clients.
C. Administering misoprostol to a pregnant client is dangerous, as it can stimulate uterine contractions and threaten the pregnancy. Monitoring for adverse reactions would not be an appropriate course of action, as the medication should not be given to begin with.
D. Even though verifying the patient's identity is always an important step, the main concern here is that misoprostol is contraindicated during pregnancy. The nurse should not administer this medication and must first clarify with the healthcare provider if it is suitable for the pregnant patient.
