A nurse is caring for a client who is taking allopurinol. Which of the following laboratory findings indicates the medication has been effective?

Decreased triglycerides

Decreased uric acid

Increased albumin

Increased potassium

Answer and Explanation

The Correct Answer is B

B. Allopurinol is primarily prescribed to lower uric acid levels in the blood. It achieves this by inhibiting the enzyme xanthine oxidase, which is involved in the production of uric acid. Lowering uric acid levels helps prevent the formation of uric acid crystals, which can lead to gout attacks or kidney stones.
A. Triglycerides are a type of fat found in the blood. Allopurinol is not directly involved in lowering triglyceride levels. Medications that are typically used to lower triglycerides include statins, fibrates, niacin, and omega-3 fatty acids.
C. Albumin is a protein found in the blood, and its levels can be affected by various factors such as liver or kidney function. Allopurinol is not known to directly influence albumin levels. Therefore, an increase in albumin would not be a laboratory finding indicative of the effectiveness of allopurinol.
D. Potassium levels in the blood can be influenced by medications, diet, kidney function, and other factors. Allopurinol is not typically associated with increasing potassium levels. In fact, certain medications used to treat gout, such as thiazide diuretics, can lead to increased potassium levels.

Correct Answer is D

Explanation

D. The INR is the standard laboratory test used to monitor the effectiveness of warfarin therapy. Warfarin interferes with the synthesis of vitamin K-dependent clotting factors, primarily factors II, VII, IX, and X. The INR provides a standardized measure of coagulation status, allowing healthcare providers to adjust warfarin dosage to maintain therapeutic anticoagulation while minimizing the risk of bleeding or thrombosis.
A. Platelets are involved in the process of blood clotting, but checking platelet levels is not specific to monitoring warfarin therapy. Platelet count may be relevant in assessing overall coagulation status, but it is not the primary laboratory value monitored for warfarin therapy.
B. OPTT measures the time it takes for blood to clot after specific clotting factors are activated. While OPTT is used to monitor the effectiveness of heparin therapy, it is not routinely monitored for warfarin therapy. Warfarin primarily affects the extrinsic pathway of the coagulation cascade, and the international normalized ratio (INR) is the standard laboratory test used to monitor warfarin therapy.
C. White blood cell count assesses the number of white blood cells in the blood and is used to evaluate the immune system and detect infections. Monitoring white blood cell count is not specific to warfarin therapy and is not routinely checked prior to administering warfarin.

A. Warfarin B. Hydrochlorothiazide C. Dicloxacillin D. Esomeprazole

Correct Answer is A

Explanation

A. Garlic may potentiate the effects of warfarin, an anticoagulant medication. When taken together, garlic can increase the risk of bleeding due to its antiplatelet properties, potentially leading to an increased risk of bruising or bleeding episodes.
B. Hydrochlorothiazide is a diuretic medication used to treat hypertension and edema. There is no known significant interaction between hydrochlorothiazide and garlic.
C. Dicloxacillin is an antibiotic medication from the penicillin class. There is no known significant interaction between dicloxacillin and garlic.
D. Esomeprazole is a proton pump inhibitor (PPI) used to reduce stomach acid production. There is no known significant interaction between esomeprazole and garlic.
