A client is receiving heparin sodium 1000 units per hour via an infusion and warfarin sodium 2.5 mg PO for thrombophlebitis in the left leg.
The nurse educates the client that heparin and warfarin are prescribed together because:
A. Smaller doses of both drugs can be used with this method.
While it might seem that smaller doses of both drugs could be used when they are prescribed together, this is not the primary reason for using heparin and warfarin together. Both drugs have different mechanisms of action and are used for their unique therapeutic effects.
B. This combination facilitates the thrombolysis more quickly.
The combination of heparin and warfarin does not facilitate thrombolysis more quickly. Thrombolysis is the process of breaking down clots, and while these medications can prevent the formation of new clots, they do not actively break down existing ones.
C. The heparin provides anticoagulation until the warfarin becomes effective.
Heparin and warfarin are often used together in the treatment of thrombophlebitis because they provide different benefits. Heparin acts quickly to prevent further clotting and allows the body to naturally break down existing clots. Warfarin, on the other hand, takes several days to become effective. Therefore, heparin is used to provide immediate anticoagulation until the warfarin becomes effective.
D. This combination provides immediate anticoagulation.
While it’s true that the combination of heparin and warfarin provides immediate anticoagulation, this is primarily due to the action of heparin. Warfarin takes several days to become effective, so it does not contribute to the immediate anticoagulant effect.

Full Explanation
Choice A rationale
While it might seem that smaller doses of both drugs could be used when they are prescribed together, this is not the primary reason for using heparin and warfarin together. Both drugs have different mechanisms of action and are used for their unique therapeutic effects.
Choice B rationale
The combination of heparin and warfarin does not facilitate thrombolysis more quickly. Thrombolysis is the process of breaking down clots, and while these medications can prevent the formation of new clots, they do not actively break down existing ones.
Choice C rationale
Heparin and warfarin are often used together in the treatment of thrombophlebitis because they provide different benefits. Heparin acts quickly to prevent further clotting and allows the body to naturally break down existing clots. Warfarin, on the other hand, takes several days to become effective. Therefore, heparin is used to provide immediate anticoagulation until the warfarin becomes effective.
Choice D rationale
While it’s true that the combination of heparin and warfarin provides immediate anticoagulation, this is primarily due to the action of heparin. Warfarin takes several days to become effective, so it does not contribute to the immediate anticoagulant effect.
Similar Questions
The nurse is caring for the following four clients on the nursing unit.
Which client is at the highest risk for the development of deep vein thrombosis?
A. 55-year-old man with a past medical history of a myocardial infarction.
While a past medical history of myocardial infarction does increase the risk of deep vein thrombosis (DVT), it is not the highest risk factor among the options provided. Other factors such as immobility, surgery, and certain medical conditions can pose a higher risk.
B. 45-year-old woman post laparoscopic knee replacement.
Postoperative patients, such as those who have had a laparoscopic knee replacement, are at an increased risk for DVT due to periods of immobility and changes in blood flow and clotting. However, the risk is not as high as in patients who have undergone major open abdominal surgery.
C. 65-year-old woman post major open abdominal surgery.
Patients who have undergone major open abdominal surgery are at the highest risk for the development of DVT among the options provided. The surgery itself, along with the postoperative period of immobility, significantly increases the risk of DVT34567.
D. 50-year-old man with a peptic ulcer.
While peptic ulcers can be associated with certain risk factors for DVT, such as age and immobility due to pain, they do not pose as high a risk as major open abdominal surgery.

A client has been taking glipizide for 6 months and reports to the nurse that their urine has become darker since starting the medication.
What should be the nurse’s initial action?
A. Review the results of liver function studies.
Dark urine can be a sign of liver dysfunction, which can be a side effect of glipizide. Therefore, reviewing the results of liver function studies would be an appropriate initial action to determine if the medication is affecting the client’s liver function.
B. Instruct the client to increase their water intake.
While increasing water intake can sometimes help with certain side effects of medications, it would not address the potential issue of liver dysfunction indicated by the dark urine.
C. Check the client’s weight.
Checking the client’s weight would not provide information related to the cause of the dark urine.
D. Test a sample of urine for the presence of occult blood.
Testing a sample of urine for the presence of occult blood could be useful if there was a suspicion of bleeding, but it would not address the potential issue of liver dysfunction indicated by the dark urine.

The nurse is preparing to administer a client’s warfarin sodium 5 mg PO at 1900. Upon entering the client’s room, the nurse finds several large, new ecchymotic areas on the client’s extremities.
What should be the nurse’s initial action?
A. Hold the warfarin until the next day’s dose and notify the laboratory.
While holding the warfarin and notifying the laboratory could be appropriate actions in some situations, they would not address the immediate concern of the large, new ecchymotic areas on the client’s extremities.
B. Administer the daily dose of warfarin and notify the healthcare provider so tomorrow’s dose can be adjusted.
Administering the daily dose of warfarin and notifying the healthcare provider for a dose adjustment the next day could potentially exacerbate the bleeding risk, given the presence of the large, new ecchymotic areas.
C. Administer the daily dose of warfarin as these are the expected side effects of the medication.
Large, new ecchymotic areas are not expected side effects of warfarin. They could indicate a serious problem such as excessive anticoagulation.
D. Hold the warfarin until the healthcare provider is notified of the assessment findings.
The presence of large, new ecchymotic areas could indicate excessive anticoagulation, which is a serious complication of warfarin therapy. Therefore, holding the warfarin and notifying the healthcare provider of the assessment findings would be the most appropriate initial action.
