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?
"I will use a soft-bristled toothbrush and an electric razor to prevent bleeding."
"I will eat more green leafy vegetables to increase my vitamin K intake."
"I will take ibuprofen instead of aspirin for pain relief."
"I will check my blood pressure regularly while taking this medication."
The Correct Answer is A
Warfarin is an anticoagulant that inhibits vitamin K-dependent clotting factors and increases the risk of bleeding. The client should use a soft-bristled toothbrush and an electric razor to prevent trauma and bleeding from minor cuts or abrasions.
A) Correct. This statement indicates that the client understands how to prevent bleeding while taking warfarin.
B) This statement indicates a lack of understanding of the teaching. The client should avoid sudden changes in vitamin K intake, as this can affect the therapeutic level of warfarin and increase the risk of clotting or bleeding. Green leafy vegetables are high in vitamin K and should be consumed in consistent amounts.
C) This statement indicates a lack of understanding of the teaching. The client should avoid nonsteroidal anti-inflammatory drugs (NSAIDs), such as ibuprofen while taking warfarin, as they can increase the risk of bleeding. The client should consult with the provider before taking any over-the-counter medications for pain relief.
D) This statement indicates a lack of understanding of the teaching. Warfarin does not affect blood pressure directly but rather affects blood clotting. The client should monitor their international normalized ratio (INR), which measures the effectiveness of warfarin, regularly while taking this medication.

Correct Answer is D
Explanation
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.
