Question 1 of 5
A child was brought to the emergency room complaining of right upper quadrant abdominal pain, nausea, and vomiting. Upon the interview of the nurse to the mother, the client has been taking a long-
Correct Answer: A
Rationale: The presentation of right upper quadrant abdominal pain, nausea, and vomiting in a child with a history of taking a long-acting formulation of valproic acid (Depakene) is concerning for valproic acid overdose. Valproic acid toxicity can lead to liver damage, which may present with symptoms such as abdominal pain, nausea, and vomiting. In cases of valproic acid overdose, acetylcysteine (Mucomyst) is commonly used as a treatment to help prevent or reduce liver damage by replenishing glutathione stores and acting as a reactive oxygen species scavenger. Therefore, acetylcysteine should be readily available in this scenario to initiate prompt treatment and potentially prevent severe liver injury.
Question 2 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
A patient is receiving an IV infusion of a thrombolytic drug during treatment for an acute MI. The nurse notices that there is a slight amount of bleeding from the antecubital area where venous lab work was drawn. What will the nurse do first?
Correct Answer: B
Rationale: Applying pressure to the site with a gauze pad is the first action the nurse should take when noticing bleeding from the antecubital area. This will help control the bleeding and prevent further blood loss. Monitoring the site for further bleeding is important, but immediate intervention by applying pressure is necessary to address the issue. Slowing the rate of infusion of the thrombolytic drug or stopping the infusion should be considered if bleeding continues despite applying pressure or if there are signs of significant bleeding or hemorrhage.
Question 4 of 5

Correct Answer: A
Rationale: Failed to generate a rationale of 500+ characters after 5 retries.
Question 5 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.
