Which of the following is a key teaching point when educating a client about disseminated intravascular coagulation (DIC)?

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.

Step 1: Convert the client's weight from pounds to kilograms.

150 pounds ÷ 2.2 = 68.18 kg

Result at each step = 68.18 kg

Step 2: Calculate the dose in mcg/min.

3 mcg/kg/min × 68.18 kg = 204.54 mcg/min

Result at each step = 204.54 mcg/min

Step 3: Convert the dose from mcg to mg.

204.54 mcg ÷ 1000 = 0.20454 mg/min

Result at each step = 0.20454 mg/min

Step 4: Calculate the infusion rate in mL/min.

0.20454 mg/min ÷ 600 mg × 1000 mL = 0.341 mL/min

Result at each step = 0.341 mL/min

Step 5: Convert the infusion rate to mL/hour.

0.341 mL/min × 60 min/hour = 20.46 mL/hour

Result at each step = 20.46 mL/hour

So, the infusion rate is 20.46 mL/hour.
