A nurse is preparing to administer intravenous Phenytoin to a patient. Which of the following actions should the nurse take to ensure proper administration?

Flush the IV line with normal saline before and after administering phenytoin

Flush the IV line with dextrose solution before and after giving phenytoin

Mix phenytoin with lactated Ringer's solution for infusion

Administer phenytoin without flushing the IV line

Answer and Explanation

The Correct Answer is A

A. Flush the IV line with normal saline before and after administering phenytoin: Phenytoin is incompatible with dextrose and many other IV solutions. Normal saline is the only recommended diluent, and flushing before and after administration prevents precipitation and line blockage, ensuring safe delivery of the drug.
B. Flush the IV line with dextrose solution before and after giving phenytoin: Phenytoin precipitates in dextrose-containing solutions, which can result in crystal formation, risking embolism or phlebitis. Using dextrose can lead to serious IV complications and must be avoided.
C. Mix phenytoin with lactated Ringer's solution for infusion: Phenytoin is not compatible with lactated Ringer’s due to the calcium content, which increases the risk of precipitation. It should only be diluted in normal saline to maintain solution stability and patient safety.
D. Administer phenytoin without flushing the IV line: Skipping the flush increases the risk of drug incompatibility, precipitation, and reduced drug delivery. Flushing with normal saline is essential to maintain IV line patency and prevent complications.

Correct Answer is D

Explanation

A. "Limit your fluid intake to meal times.": Fluid restriction is not a standard recommendation for patients taking Verapamil unless they have another condition like heart failure. Adequate hydration is important, especially to counter constipation, a known side effect of the drug.
B. "You can expect swelling of the ankles while taking this medication.": While peripheral edema is a known side effect of Verapamil, it is not something patients should expect or accept without reporting. Significant swelling may require dose adjustment or switching medications.
C. "This medication will not affect your heart rate": Verapamil is a calcium channel blocker that slows AV node conduction and reduces heart rate. It is used for conditions like hypertension, angina, and arrhythmias, and can cause bradycardia, especially in high doses.
D. "Increase your daily intake of dietary fiber.": Verapamil frequently causes constipation by decreasing gastrointestinal motility. Increasing dietary fiber, fluid intake, and physical activity are recommended to minimize this side effect and promote regular bowel movements.
