Question

The client is receiving Heparin IV at 1200 units/hour as part of the treatment regime for pulmonary embolism. The nurse notes that the urine has become bright red in color. The nurse would prepare to administer which of the following medications? A. Protamine Sulfate B. Aquamephyton (vitamin K) C. Warfarin (Coumadin) D. Acetylcysteine (Mucomyst)

Short answer

The nurse would prepare to administer Protamine Sulfate, which is the antidote for Heparin.

Step-by-step solution

Identify the Cause of Symptom

Bright red urine is an indication of possible bleeding. The patient is on Heparin, an anticoagulant, which can cause bleeding as a side effect.

Determine the Appropriate Intervention

In case of heparin overdose or complications leading to bleeding, Protamine Sulfate is the antidote that can be administered to reverse the effects of Heparin.

Exclude Other Medication Options

Other listed medications such as Aquamephyton (vitamin K) and Warfarin (Coumadin) are not appropriate in this case as they are used to treat and prevent blood clots, not to reverse anticoagulation. Acetylcysteine (Mucomyst) is used to treat acetaminophen overdose and is not relevant to anticoagulation or bleeding.

Key concepts

Heparin IV Therapy

Heparin IV therapy is a critical treatment for patients who are at risk of or are currently experiencing conditions such as deep vein thrombosis, pulmonary embolism, and certain types of heart attacks. Heparin works by inhibiting clotting factors in the blood, effectively reducing the formation of clots. When administered intravenously, the onset of action is immediate, which is crucial in acute settings.

However, the therapeutic window for heparin is narrow, meaning the difference between an effective dose and a potentially harmful dose is small. Nurses and healthcare providers must meticulously monitor patients receiving Heparin IV therapy. Standard protocols include frequent checks of the patient's activated partial thromboplastin time (aPTT) to ensure the blood's clotting ability is within a safe and therapeutic range.

Moreover, all healthcare providers must have a strong understanding of both the dosing and the rate of administration for Heparin IV treatments. Any inaccuracies can lead to serious consequences; therefore, a high level of precision and care is necessary during the entire course of the therapy.

Anticoagulant Complications

Anticoagulants are lifesaving medications but carry a significant risk of bleeding complications. The use of Heparin IV, while beneficial for preventing and treating clots, must be monitored closely for any signs of hemorrhage. Bleeding can be external or internal, and in the context of the exercise, bright red urine is a clear indication of possible internal bleeding, possibly from the urinary tract or bladder.

The immediate complications of anticoagulant therapy, such as minor bruising or severe bleeding, need prompt response and treatment. Protamine Sulfate is the reversal agent for heparin-induced bleeding and works by binding to heparin, neutralizing its effects. It is crucial for healthcare professionals to be aware of the specific reversal strategies for each anticoagulant they administer to mitigate the risks and respond effectively to any bleeding complications.

Medication Administration

The administration of medication, particularly in the case of critical drugs like anticoagulants, must adhere strictly to evidence-based protocols. To prevent medication errors, a thorough understanding of the drug, its indications, contraindications, and potential side effects is mandatory.

During Heparin IV administration, the nurse must use the 'five rights': the right patient, the right drug, the right dose, the right route, and the right time. Furthermore, additional safety procedures include double-checking calculations, verifying orders with a second nurse, and continuously monitoring the patient for any adverse reactions. This vigilant approach to medication administration safeguards against potentially harmful consequences and ensures the best possible patient outcomes. In the event of an adverse reaction, such as the onset of bleeding seen with Heparin IV therapy, the nurse must be ready to administer the appropriate antidote promptly, which in this case is Protamine Sulfate.
