Question 1 of 5
A patient who has been anticoagulated with warfarin (Coumadin) has been admitted for gastrointestinal bleeding. The history and physical examination indicates that the patient may have taken too much warfarin. The nurse anticipates that the patient will receive which antidote?
Correct Answer: B
Rationale: Vitamin K is the antidote for warfarin (Coumadin) toxicity. Warfarin is a vitamin K antagonist that inhibits the synthesis of vitamin K-dependent coagulation factors (II, VII, IX, X) in the liver. In cases of excessive anticoagulation and bleeding, administering vitamin K can help reverse the effects of warfarin by replenishing the depleted vitamin K-dependent clotting factors. Vitamin K helps the liver produce clotting factors, thereby promoting the clotting process and reversing the excessive anticoagulant effects of warfarin. Other options mentioned, such as Vitamin E, Protamine sulfate, and Potassium chloride, are not appropriate antidotes for warfarin toxicity.

Question 3 of 5
Which of the following drugs has a therapeutic effect that increases cardiac output and slows heart rate?
Correct Answer: C
Rationale: Digoxin is a medication commonly used to treat heart failure and certain types of irregular heartbeats. It works by increasing the force of contraction of the heart muscle, thereby increasing cardiac output. Additionally, digoxin also has the ability to slow down the heart rate, making it helpful in conditions such as atrial fibrillation. Heparin is an anticoagulant medication used to prevent blood clot formation, while Alprazolam is a benzodiazepine used to treat anxiety disorders. Levothyroxine is a thyroid hormone replacement medication to treat hypothyroidism. None of these drugs have the therapeutic effects of increasing cardiac output and slowing heart rate like digoxin.
Question 4 of 5
Which of the following medications would you administer for an overdose of acetaminophen?
Correct Answer: C
Rationale: Acetylcysteine is the specific antidote for acetaminophen overdose. Acetaminophen (also known as paracetamol) toxicity can cause severe liver damage if not treated promptly. Acetylcysteine works by replenishing the depleted glutathione stores in the liver, helping to prevent liver damage and improving the patient's outcome. Naloxone is used for opioid overdose, vitamin K for reversing the effects of certain anticoagulants, and atropine for specific heart and nerve related conditions.
Question 5 of 5
A nurse is caring for a patient who is taking Digoxin. The nurse should instruct the patient to monitor and report which of the following adverse e昀昀ects? ( select all the apply)
Correct Answer: A
Rationale: Failed to generate a rationale of 500+ characters after 5 retries.
