A nurse is explaining the need for combination anticoagulation therapy using heparin and warfarin to a client. Which of the following statements should the nurse use in the explanation?
Heparin and warfarin work together to lower blood pressure.
Heparin and warfarin work together to dissolve the clots.
Heparin and warfarin work together to prevent future clots from forming.
Heparin and warfarin should not be given together due to a high risk of hemorrhage.
The Correct Answer is C
Rationale:
A. Heparin and warfarin do not work to lower blood pressure. Their primary action is to prevent blood clots, not to affect blood pressure.
B. While heparin can help prevent the extension of existing blood clots, it does not typically dissolve clots. Warfarin is used for long-term anticoagulation and works by inhibiting the synthesis of clotting factors.
C. Heparin is often used initially to rapidly anticoagulate a patient while waiting for the therapeutic effects of warfarin to take effect. Warfarin is then used long-term to prevent future clots from forming.
D. Heparin and warfarin are often given together initially, especially in certain clinical situations such as acute deep vein thrombosis or pulmonary embolism, to achieve rapid anticoagulation while waiting for the therapeutic effects of warfarin. However, careful monitoring is required to minimize the risk of hemorrhage.

Correct Answer is ["125"]
Explanation
To calculate the IV pump rate in mL/hr, you can use the following formula:
IV pump rate (mL/hr)=Total volume of infusion (mL)/Total time for infusion (hours)
Total volume of infusion=500 mL Total time for infusion=4 hours
IV pump rate (mL/hr)=500 mL/4 hours
=125mL/hr
So, the nurse should set the IV pump to deliver 125 mL/hr.
Correct Answer is ["B","D","E"]
Explanation
Rationale:
A. Ethnicity may contribute to an individual's risk of atherosclerosis due to socioeconomic factors and access to healthcare, but it is not considered a modifiable risk factor.
B. Diabetes is a modifiable risk factor for atherosclerosis. Individuals with diabetes are at increased risk of atherosclerosis due to factors such as hyperglycemia, insulin resistance, and dyslipidemia.
C. Genetic predisposition may increase an individual's susceptibility to atherosclerosis, but it is not a modifiable risk factor.
D. Inactivity, or lack of regular physical activity, is a modifiable risk factor for atherosclerosis.
Regular exercise helps maintain cardiovascular health and reduces the risk of atherosclerosis.
E. Diet, specifically a diet high in saturated fats, trans fats, cholesterol, and sodium, is a modifiable risk factor for atherosclerosis. A diet high in fruits, vegetables, whole grains, and lean proteins can help reduce the risk of atherosclerosis.
