A nurse is preparing to administer erythromycin PO to a client who has an infection. The nurse checks the client's medical record and notes that the client has a severe allergy to penicillin. Which of the following actions should the nurse take?
Request a different medication from the provider
Administer the medication to the client.
Premedicate the client with diphenhydramine.
Request a different route of administration from the provider.
The Correct Answer is B
A. There is no need for change of antibiotic as there is no cross-rectivity between macrolides and penicillins.
B. Given the client's severe allergy to penicillin, it would be safe to administer erythromycin, a macrolide, as there is no risk of cross-reactivity.
C. Diphenhydramine is an antihistamine commonly used to treat allergic reactions, but premedicating the client with diphenhydramine is not necessary.
D. Changing the route of administration would not alter the risk of an allergic reaction.

Correct Answer is B
Explanation
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 C
Explanation
A. Nitroglycerin patches should not be removed for routine activities like bathing unless specifically instructed.
B. Nitroglycerin is used to treat hypertension, not induce it. Monitoring for hypertension after applying the patch is unnecessary.
C. To prevent skin irritation and tolerance to the medication, it is important to rotate the application sites when using a transdermal patch. This allows the skin to recover and helps maintain the effectiveness of the medication.
D. Nitroglycerin patches are typically worn continuously for 12 to 14 hours and then removed for a 10- to 12-hour nitrate-free interval to prevent tolerance to the medication.
