The nurse in a medical unit is caring for a client with heart failure. The client suddenly develops extreme dyspnea, tachycardia, and lung crackles, and the nurse suspects pulmonary edema. The nurse immediately asks another nurse to contact the healthcare provider and prepares to implement which priority interventions? (Select all that apply.)

Choice A reason: The statement that the antidote for warfarin is protamine is incorrect. The primary antidote for warfarin is Vitamin K, and in cases of significant bleeding, prothrombin complex concentrate (PCC) or fresh frozen plasma (FFP) may be used¹². Protamine is used as an antidote for heparin, not warfarin¹.

Choice B reason: Observing the client for manifestations of hemorrhage is a critical nursing action when administering warfarin. Warfarin is an anticoagulant, and one of the major risks associated with its use is bleeding. The nurse should monitor for signs such as unusual bruising, petechiae, hematuria, tarry stools, or any other indications of internal or external bleeding⁷⁸.

Choice C reason: Monitoring the client's aPTT (activated partial thromboplastin time) is not typically associated with warfarin therapy. Warfarin's effect is monitored through the prothrombin time (PT) and the International Normalized Ratio (INR), not aPTT, which is more commonly used to monitor heparin therapy⁴⁵.

Choice D reason: Warfarin should not be administered along with NSAIDs without careful consideration and monitoring due to the increased risk of bleeding. NSAIDs can affect platelet function and gastrointestinal mucosa, leading to an elevated risk of gastrointestinal bleeding when taken with warfarin¹¹¹².

Choice A reason : Anticoagulants are medications that prevent blood clots. They are not typically used to manage fluid volume excess in left-sided heart failure. Instead, they may be used if the patient has an increased risk of clotting due to reduced mobility or atrial fibrillation, which can be associated with heart failure⁵.

Choice B reason : Antiembolism stockings are used to prevent deep vein thrombosis (DVT) and are not directly related to the management of fluid volume excess. They may be used in heart failure patients to prevent DVT due to reduced mobility but do not aid in fluid reduction⁵.

Choice C reason : Oxygen therapy can be used in left-sided heart failure to alleviate symptoms of dyspnea due to pulmonary congestion. However, it does not directly reduce fluid volume excess. It is a supportive treatment to ensure adequate oxygenation⁵.

Choice D reason : Diuretics are the primary treatment for reducing fluid volume excess in left-sided heart failure. They work by increasing urine output, which helps to reduce the volume of fluid in the body and alleviate symptoms such as pulmonary edema and peripheral edema⁵.
