A nurse is teaching a client who has a new prescription for warfarin. Which of the following statements by the client indicates a need for further teaching?

A) Incorrect. Morphine sulfate does not need to be diluted in normal saline before administration. Diluting the medication can reduce its potency and effectiveness.

B) Correct. Morphine sulfate should be injected slowly over 1 to 2 minutes to prevent adverse effects, such as hypotension, respiratory depression, and nausea.

C) Incorrect. Heparin is not indicated for flushing the IV line before and after administration of morphine sulfate. Heparin is an anticoagulant that can increase the risk of bleeding. The IV line should be flushed with normal saline or sterile water to prevent medication incompatibility and ensure complete delivery of the medication.

D) Incorrect. The nurse should monitor the client's respiratory rate more frequently than every 15 minutes, as morphine sulfate can cause respiratory depression. The nurse should monitor the client's respiratory rate before, during, and after administration of the medication, and at least every 5 minutes until the client's pain is relieved.

A) Incorrect. The client should not avoid eating foods that are high in vitamin K, such as leafy green vegetables, because they can interfere with the anticoagulant effect of warfarin. The client should maintain a consistent intake of vitamin K and follow a balanced diet.

B) Correct. The client should use a soft-bristled toothbrush to prevent bleeding from the gums, which can occur due to the increased risk of bleeding caused by warfarin. The client should also avoid using dental floss and electric razors.

C) Correct. The client should monitor their blood pressure regularly at home, as warfarin can affect blood pressure and increase the risk of stroke or bleeding complications. The client should report any abnormal readings to their provider.

D) Correct. The client should report any signs of bruising or bleeding to their provider, as they may indicate an adverse reaction to warfarin or an overdose. The client should also report any signs of infection, such as fever, sore throat, or pus, as they may increase the risk of bleeding.
