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?

Review the results of liver function studies.

Instruct the client to increase their water intake.

Check the client’s weight.

Test a sample of urine for the presence of occult blood.

Answer and Explanation

The Correct Answer is A

Choice A rationale

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.

Choice B rationale

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.

Choice C rationale

Checking the client’s weight would not provide information related to the cause of the dark urine.

Choice D rationale

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.

Correct Answer is A

Explanation

Choice A rationale

Deep vein thrombosis (DVT) is a condition characterized by the formation of a blood clot in a deep vein, usually in the leg. One of the most common symptoms of DVT is swelling of the affected extremity. This occurs because the blood clot obstructs the flow of blood, causing fluid to build up in the tissues.

Choice B rationale

While redness can be a symptom of DVT, it is not typically confined to a small area. Instead, redness associated with DVT is usually more widespread and is often accompanied by other symptoms such as swelling and pain.

Choice C rationale

A cool, mottled extremity is not a typical symptom of DVT34. DVT usually causes the affected area to feel warmer than the surrounding areas due to inflammation caused by the blood clot.

Choice D rationale

The presence of bilateral peripheral pulses is not a specific finding for DVT34. In fact, the presence of strong peripheral pulses may suggest that blood flow is not significantly obstructed.

A. Smaller doses of both drugs can be used with this method. B. This combination facilitates the thrombolysis more quickly. C. The heparin provides anticoagulation until the warfarin becomes effective. D. This combination provides immediate anticoagulation.

Correct Answer is C

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.
