These occur due to the estrogen component, which increases the risk of blood clots. While headaches, dizziness, and breakthrough bleeding are common side effects, they are not as severe as thromboembolic events.

- A. Protamine sulfate
- B. Alteplase (Activase, Cathflo Activas
- D. Reteplase (Retavas

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.

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.
