Susan, the nurse, is caring for a client who has DIC. Which of the following medications should the nurse anticipate administering?

Vitamin K

Statin

Heparin

Metformin

Answer and Explanation

The Correct Answer is C

Choice A: Vitamin K
Vitamin K is essential for the synthesis of clotting factors and is often used to treat bleeding disorders caused by vitamin K deficiency or to reverse the effects of anticoagulants like warfarin. However, in the context of disseminated intravascular coagulation (DIC), the primary issue is not a deficiency of clotting factors but rather an overactivation of the clotting cascade leading to both clot formation and bleeding. Therefore, while vitamin K can be beneficial in certain bleeding disorders, it is not the primary treatment for DIC.

Choice B: Statin
Statins are medications used to lower cholesterol levels and reduce the risk of cardiovascular disease. They work by inhibiting the enzyme HMG-CoA reductase, which plays a crucial role in cholesterol synthesis. Statins are not used in the management of DIC as they do not address the underlying pathophysiology of the condition, which involves widespread clotting and subsequent bleeding.

Choice C: Heparin
Heparin is an anticoagulant that helps prevent the formation of new clots and the extension of existing clots. In the management of DIC, heparin can be used to interrupt the clotting process and prevent further consumption of clotting factors. This can help stabilize the patient and reduce the risk of severe bleeding. Heparin is particularly useful in cases where thrombosis is predominant. It is important to monitor the patient closely to balance the risk of bleeding with the benefits of anticoagulation.

Choice D: Metformin
Metformin is an oral hypoglycemic agent used to manage type 2 diabetes by improving insulin sensitivity and reducing glucose production in the liver. It has no role in the treatment of DIC, as it does not affect the coagulation pathways or the underlying causes of DIC.

Correct Answer is ["A","B","C","D","E"]

Explanation

Choice A Reason:
Cancer is a significant risk factor for DIC, particularly certain types of leukemia and metastatic cancers. Cancer can trigger DIC through the release of procoagulant substances from tumor cells, leading to widespread clotting and subsequent bleeding. The hypercoagulable state associated with malignancies increases the risk of thrombotic events, which can precipitate DIC. Patients with advanced cancer are particularly susceptible due to the aggressive nature of the disease and the body's inflammatory response.

Choice B Reason:
Sepsis is one of the most common causes of DIC. Sepsis triggers a systemic inflammatory response that activates the coagulation cascade, leading to the formation of microthrombi throughout the vasculature. This widespread clotting depletes clotting factors and platelets, resulting in a paradoxical increase in bleeding risk. The severity of sepsis correlates with the likelihood of developing DIC, making early recognition and treatment of sepsis crucial.

Choice C Reason:
Trauma can lead to DIC through extensive tissue injury and the release of tissue factor into the bloodstream. Severe trauma, such as that from major accidents or surgeries, can overwhelm the body's hemostatic mechanisms, leading to uncontrolled clotting and bleeding. The inflammatory response to trauma further exacerbates the coagulation process, increasing the risk of DIC. Prompt management of traumatic injuries and monitoring for signs of DIC are essential in these patients.

Choice D Reason:
Pregnancy complications such as placental abruption, amniotic fluid embolism, and severe preeclampsia can precipitate DIC. These conditions cause significant endothelial damage and the release of procoagulant substances, triggering the coagulation cascade. The physiological changes during pregnancy, including increased blood volume and hypercoagulability, further predispose pregnant women to DIC. Early intervention and management of pregnancy-related complications are vital to prevent DIC.

Choice E Reason:
Blood transfusion reactions can lead to DIC through immune-mediated mechanisms. Incompatible blood transfusions can cause hemolysis and the release of procoagulant substances, initiating the coagulation cascade. The resulting widespread clotting and consumption of clotting factors can lead to bleeding complications. Careful matching of blood products and monitoring for transfusion reactions are critical to prevent DIC in transfusion recipients.

A. Elevate the client's head on two pillows. B. Keep the client well hydrated. C. Decrease the noise level in the client's room. D. Suction the endotracheal tube frequently.

Correct Answer is C

Explanation

Choice A Reason:
Elevating the client's head on two pillows can help reduce ICP by promoting venous drainage from the brain. However, it is important to ensure that the head is not elevated too high, as this can impede venous return and potentially increase ICP. The recommended elevation is typically 30 degrees. While this intervention is beneficial, it is not the most critical action compared to reducing environmental stimuli.

Choice B Reason:
Keeping the client well hydrated is essential for overall health, but excessive hydration can increase ICP by increasing the volume of cerebrospinal fluid and blood within the cranial vault. Fluid management must be carefully monitored to avoid exacerbating ICP. Therefore, while hydration is important, it must be balanced and not excessive.

Choice C Reason:
Decreasing the noise level in the client's room is crucial for minimizing external stimuli that can increase ICP. Noise and other environmental stressors can lead to increased agitation and stress, which in turn can elevate ICP. Creating a calm and quiet environment helps in maintaining a stable ICP and is a non-invasive, easily implementable intervention.

Choice D Reason:
Frequent suctioning of the endotracheal tube can cause transient increases in ICP due to the stimulation and potential for coughing. While suctioning is necessary to maintain airway patency, it should be performed judiciously and only when clinically indicated. Over-suctioning can lead to spikes in ICP and should be avoided.
