The nurse is caring for a patient receiving warfarin and notes bruising and petechiae on the patient's extremities.
The nurse will request an order for which?
Vitamin K Level.
PTT and aPTT.
International normalized ratio (INR).
Platelet level.
The Correct Answer is C
Choice A rationale
Checking vitamin K levels doesn't directly monitor warfarin's effect.

Choice C rationale
INR specifically measures warfarin's effectiveness and safety.

Platelet levels don't monitor the anticoagulant effect of warfarin.

Correct Answer is B
Explanation
Choice A rationale
Administering a non-steroidal anti-inflammatory drug (NSAID) is not a priority action for a patient who has received a narcotic analgesic. The priority should be to ensure the patient’s safety and prevent falls, which can occur due to the sedative effects of narcotics.
Choice B rationale
Putting side rails up and placing the bed in the lowest position is essential for patient safety. Narcotics can cause dizziness, drowsiness, and impaired coordination, increasing the risk of falls. Ensuring the bed is in the lowest position and side rails are up helps prevent injury if the patient tries to get up.
Choice C rationale
Encouraging fluids is beneficial for many patients, but it is not the priority action when a patient has received a narcotic analgesic. Hydration is important but secondary to ensuring the patient’s immediate safety.
Choice D rationale
Creating a restful, dark environment may help the patient rest, but it does not directly address the immediate safety needs of a patient who has received a narcotic analgesic. The focus should be on preventing falls and injury.
Correct Answer is A
Explanation
Choice A rationale
Treatment of narcotic dependence involves using a narcotics antagonist to block the effects of narcotics. This helps prevent relapse in patients recovering from narcotic addiction by decreasing cravings and withdrawal symptoms.
Choice B rationale
Treatment of alcohol dependence does not typically involve narcotics antagonists. Instead, medications like disulfiram or naltrexone are used to manage alcohol dependence.
Choice C rationale
Reversal of tachycardia is not an indication for a narcotics antagonist. Tachycardia is usually managed with medications like beta-blockers or calcium channel blockers.
Choice D rationale
Reversal of bronchoconstriction is not an indicator for narcotics antagonists. Bronchoconstriction is usually treated with bronchodilators such as albuterol or ipratropium.
