The patient accidentally takes too much of the prescribed warfarin (Coumadin) and is readmitted to the hospital with bleeding. Which drug can the nurse anticipates administrating?
- A. Protamine sulfate
- B. Alteplase (Activase, Cathflo Activas
- D. Reteplase (Retavas
Correct Answer: D
Rationale: Warfarin, also known as Coumadin, is an anticoagulant medication that works by inhibiting the production of clotting factors in the liver, specifically factors II, VII, IX, and X. In the event of warfarin overdose, which can lead to excessive bleeding, the antidote is vitamin K. Vitamin K promotes the production of these clotting factors and helps reverse the effects of warfarin. Therefore, in this situation, the nurse can anticipate administering vitamin K to the patient to help stop the bleeding caused by the excess warfarin in the system.

Which drug concentration is appropriate to administer in an order for epinephrine 0.3 mg IM to treat a severe allergic reaction in an adult patient?
- A. 1:10,000
- B. 0.736111111
- C. 0.111111111
- D. 1:10
Correct Answer: B
Rationale: The appropriate concentration for epinephrine 0.3 mg IM in an adult for a severe allergic reaction is 1:1000. This concentration is used for intramuscular administration, while 1:10,000 (A) is used for intravenous administration in cardiac arrest. Concentrations of 1:100 (C) and 1:10 (D) are not standard for this purpose.
Which patient-teaching instructions are appropriate for a patient taking an antidysrhythmic drug? (Select all that apply.)
- A. Do not chew or crush extende
- B. release forms of medication.
- C. Take the medication with food if gastrointestinal distress occurs.
- D. If a dose is missed, the missed dose should be taken along with the next dose that is due to be taken.
Correct Answer: A
Rationale: A. Do not chew or crush extended-release forms of medication. This is an appropriate instruction because chewing or crushing extended-release forms of medication can alter their intended time-release action, leading to an overdose or underdose.
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?
- A. Monitor the site for further bleeding.
- B. Apply pressure to the site with a gauze pa
- D. Slow the rate of infusion of the thrombolytic drug.
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.
Which of the following drugs has a therapeutic effect that increases cardiac output and slows heart rate?
- A. Heparin
- B. Alprazola
- C. Digoxin
- D. Levothyroxine
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.
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-
- A. Which of the following medications should be readily available?
- B. naltrexone (ReVi
- C. urea (Ureaphil)
- D. acetylcysteine (Mucomyst)
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.
