Editing Pharmacology – RN Practice Questions (section)

==Question 3==
'''Select all that apply.''' The nurse is discharging a client newly prescribed warfarin for atrial fibrillation. Which statements by the client indicate correct understanding?
# "I will use an electric razor and a soft toothbrush."
# "I will completely stop eating green leafy vegetables."
# "I will call my provider if my stools look black and tarry."
# "I will take ibuprofen for my arthritis pain instead of acetaminophen."
# "I will tell any new provider or dentist that I take a blood thinner."
# "I will have my INR checked as scheduled even if I feel fine."

'''Answer:''' 1, 3, 5, and 6 (A, C, E, F).

''Rationale:'' Options 1, 3, 5, and 6 are correct bleeding precautions and monitoring behaviors. Option 2 is wrong because the teaching is '''consistent''' intake of vitamin K containing foods, not elimination; erratic intake, in either direction, destabilizes the INR. Option 4 is wrong because NSAIDs such as ibuprofen add antiplatelet effect and gastrointestinal mucosal injury on top of anticoagulation and markedly raise bleeding risk; acetaminophen within recommended limits is generally the preferred analgesic, though high sustained doses can also elevate the INR and warrant monitoring.
