A patient with gout has been instructed on the prescribed medication allopurinol (Zyloprim). Which patient statement indicates understanding of the action of this medication?
It increases formation of purines.
It blocks formation of uric acid.
It increases metabolism of purines.
It excretes proteins.
The Correct Answer is B
A. It increases formation of purines: This is incorrect. Allopurinol works by inhibiting the enzyme xanthine oxidase, which is involved in the conversion of purines to uric acid. Therefore, it reduces, rather than increases, uric acid formation.
B. It blocks formation of uric acid: This is correct. Allopurinol decreases uric acid production by inhibiting the enzyme xanthine oxidase, which converts xanthine to uric acid, thus helping to prevent gout attacks and manage chronic gout.
C. It increases metabolism of purines: Allopurinol does not increase the metabolism of purines. Instead, it reduces the conversion of purines to uric acid, which is the substance that accumulates and causes gout.
D. It excretes proteins: Allopurinol does not facilitate the excretion of proteins. Its primary action is to reduce the production of uric acid.

Correct Answer is A
Explanation
Correct answer: A
A. Monitoring for infection: Infection is a significant risk with external fixation devices due to the presence of pins that penetrate the skin and soft tissues. Monitoring for signs of infection, such as redness, swelling, discharge, or increased pain, is crucial.
B. Monitoring circulatory status: While circulatory status is important, especially in cases of limb injury or immobilization, it is not the most immediate concern compared to the risk of infection from the external fixation device.
C. Validating proper mobility: Ensuring proper mobility is important, but it is secondary to the prevention and detection of infection. Mobility assessments can be done after confirming that there are no infections or complications.
D. Checking discomfort level: While assessing discomfort is important for pain management and comfort, it is not as critical as monitoring for infection, which can lead to severe complications if not addressed promptly.
Correct Answer is D
Explanation
A. Ecchymosis: Ecchymosis (bruising) is not a typical symptom of peripheral arterial occlusive disease. It generally indicates bleeding or trauma to the skin and subcutaneous tissues.
B. Stasis ulcers: Stasis ulcers are associated with chronic venous insufficiency, not peripheral arterial disease.
C. Angina: Angina refers to chest pain due to reduced blood flow to the heart, and it is associated with coronary artery disease, not peripheral arterial occlusive disease.
D. Intermittent claudication: This is the classic symptom of peripheral arterial occlusive disease, characterized by muscle pain or cramping in the legs triggered by physical activity and relieved by rest. It is due to insufficient blood flow to the muscles during exercise.
