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
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 B
Explanation
B. Fatty foods can delay the absorption of sildenafil, potentially delaying its onset of action. While it's not necessary to completely avoid fatty foods, consuming a high-fat meal shortly before taking sildenafil may delay its effects. Therefore, it's advisable to avoid large, high-fat meals before taking sildenafil to optimize its effectiveness.
A. Sildenafil is typically taken on an as-needed basis, approximately 30 minutes to 1 hour before anticipated sexual activity. Taking sildenafil more than once a day is not recommended and can increase the risk of adverse effects and complications.
C. Sildenafil is a medication used to treat erectile dysfunction by improving blood flow to the penis, but it does not protect against sexually transmitted diseases (STDs).
D. Constipation is not a common side effect of sildenafil. Common side effects of sildenafil include headache, flushing, indigestion, nasal congestion, and dizziness. Constipation is not typically associated with sildenafil use.
Correct Answer is C
Explanation
C. Sublingual nitroglycerin is rapidly absorbed through the mucous membranes under the tongue, and its effects are usually felt within 1 to 5 minutes. Patients should experience relief from angina symptoms shortly after administration.
A. While sublingual nitroglycerin can be taken every 5 minutes for a maximum of three doses for acute angina attacks, it should not be taken every 10 minutes. Taking it too frequently can lead to excessive vasodilation and potentially harmful side effects.
B. Nitroglycerin primarily dilates blood vessels rather than affecting heart rate. While it may cause a transient decrease in blood pressure, it does not typically slow heart rate.
D. Sublingual nitroglycerin should be taken on an empty stomach for optimal absorption. Food can delay absorption and decrease the effectiveness of the medication.
