A nurse is teaching a client who has a new prescription for warfarin about safe medication practices. Which of the following statements by the client indicates an understanding of the teaching?

The nurse should stop the infusion and remove the IV catheter as soon as possible if phlebitis is suspected. Phlebitis is inflammation of a vein that can be caused by mechanical, chemical, or infectious factors. Potassium chloride is a vesicant medication that can cause severe tissue damage if it extravasates into the surrounding tissues.

The nurse should apply a warm compress to the infusion site after removing the IV catheter to reduce inflammation and discomfort. The nurse should notify the provider and obtain an order for a different IV site to continue the infusion of potassium chloride at a different location. The nurse should not slow down the infusion rate and monitor the client because this could worsen the condition and increase the risk of complications.

b) Incorrect. This is an appropriate action after removing the IV catheter, but not before.

c) Incorrect. This is an appropriate action after removing the IV catheter and applying a warm compress, but not before.

d) Incorrect. This is not an appropriate action because it could worsen the condition and increase the risk of complications.

The nurse should rotate the injection sites among different muscle groups to prevent tissue damage, irritation, and absorption problems. The nurse should follow the recommended sites for intramuscular injections, such as the deltoid, ventrolateral, vastus lateralis, and dorsogluteal muscles.

A) This is not an action to prevent medication errors, but rather an action to prevent leakage of the medication from the injection site and reduce pain and irritation. The Z-track method involves pulling the skin to one side before inserting the needle and releasing it after withdrawing the needle.

B) This is not an action to prevent medication errors, but rather an action to prevent injecting the medication into a blood vessel. Aspiration involves pulling back on the plunger of the syringe before injecting the medication and checking for blood return in the syringe.

C) This is not an action to prevent medication errors, but rather an action to enhance absorption and reduce pain and irritation. Massage involves applying gentle pressure to the injection site after administering the medication.

D) Correct. This is an action to prevent medication errors by avoiding repeated injections in the same muscle group.
