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:

Smaller doses of both drugs can be used with this method.

This combination facilitates the thrombolysis more quickly.

The heparin provides anticoagulation until the warfarin becomes effective.

This combination provides immediate anticoagulation.

Answer and Explanation

The Correct Answer is C

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.

Correct Answer is A

Explanation

Choice A rationale

Trimethoprim-sulfamethoxazole is an antibiotic used to treat or prevent bacterial infections. One of the key instructions for patients taking this medication is to increase fluid intake to 3 to

4 liters per 24 hours. This is because the medication can crystallize in the urine, which can lead to kidney stones or damage if the patient is not adequately hydrated.

Choice B rationale

Spending time in the sun does not improve the metabolism of trimethoprim-sulfamethoxazole. In fact, the medication can make the skin more sensitive to the sun, increasing the risk of sunburn.

Choice C rationale

Taking Kaopectate daily to prevent diarrhea is not a standard instruction for patients taking trimethoprim-sulfamethoxazole. Diarrhea can be a side effect of the medication, but it should be managed under the guidance of a healthcare provider.

Choice D rationale

There is no specific instruction to take trimethoprim-sulfamethoxazole every morning at the same time as hydrochlorothiazide. The timing of medication administration should be determined by the healthcare provider based on the patient’s overall treatment plan.

A. Elevate the feet for 30 minutes after walking. B. Avoid exercise that increases the heart rate. C. Continue walking to the point of pain. D. Do not walk if a leg ulcer develops.

Correct Answer is C

Explanation

Choice A rationale

Elevating the feet for 30 minutes after walking is not specifically beneficial for a patient with peripheral arterial disease (PAD). While elevation can help with conditions like edema, it does not directly address the issues associated with PAD12.

Choice B rationale

Avoiding exercise that increases the heart rate is not the best advice for a patient with PAD. Exercise, including activities that increase heart rate, can actually be beneficial. It can help improve circulation, which is often compromised in PAD12.

Choice C rationale

Continuing to walk to the point of pain is beneficial for patients with PAD. Walking, especially at a high intensity, can help improve symptoms of PAD. It can increase blood flow and oxygen supply to the muscles, which can help manage PAD symptoms.

Choice D rationale

While it’s important to care for any ulcers that develop and seek medical attention, stopping walking altogether if a leg ulcer develops is not necessary. Walking is a low-impact activity that can help improve mobility over time.
