A nurse is caring for a client who has a prescription for a hypotonic IV fluid. Which of the following solutions should the nurse expect to administer?
Lactated Ringer's
0.9% sodium chloride
3% sodium chloride
0.45% sodium chloride
The Correct Answer is D
A. Lactated Ringer's: This solution is isotonic and is typically used for fluid resuscitation, not for hypotonic treatment.
B. 0.9% sodium chloride: This is isotonic saline and does not qualify as a hypotonic solution.
C. 3% sodium chloride: This solution is hypertonic and used to treat severe hyponatremia, not hypotonic hydration.
D. 0.45% sodium chloride: This is the correct choice as it is a hypotonic solution that can help to hydrate cells by providing free water.

Correct Answer is B
Explanation
A. Brimonidine should not be instilled while wearing contact lenses; the client should remove them and wait at least 15 minutes before reinsertion.
B. Mild eye irritation, stinging, or burning is a common side effect of brimonidine and is an expected finding.
C. Brimonidine is used as a long-term treatment for open-angle glaucoma; it is not discontinued after a short course like 3 weeks.
D. Brimonidine does not change eye color; this is an effect associated with prostaglandin analogs such as latanoprost.
Correct Answer is C
Explanation
A. Requesting a serum trough level blood draw for 60 min after completion of infusion is incorrect. Trough levels should be drawn just before the next dose (not after infusion completion) to ensure therapeutic drug levels and avoid toxicity.
B. Changing the infusion site after each dose administration is incorrect. Vancomycin can cause phlebitis, but routine site changes after every dose are unnecessary unless signs of irritation or infiltration are present.
C. Contacting the provider for prescription clarification is correct. Vancomycin should be infused over at least 60 minutes to reduce the risk of Red Man Syndrome, a histamine reaction that can cause flushing, hypotension, and rash. A 30-minute infusion is too rapid and should be adjusted.
D. Requesting a serum peak level to be drawn 30 min prior to infusion is incorrect. Peak levels are drawn 30–60 minutes after infusion completion, not before infusion. Trough levels, not peak levels, are used to monitor vancomycin dosing.
