A nurse is caring for a client who has a new prescription for a nitroglycerin transdermal patch. Which of the following actions should the nurse take?
Take the patch off prior to bathing the client.
Monitor for hypertension after application of the patch.
Rotate the application sites of the patch.
Remove the patch every 24 hr
The Correct Answer is C
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.

Correct Answer is A
Explanation
A. Celecoxib is contraindicated in individuals with a history of hypersensitivity reactions, including anaphylaxis, angioedema, or urticaria, to sulfonamides. Sulfonamide antibiotics are structurally related to sulfonamide nonantibiotics, including celecoxib, and cross-sensitivity reactions may occur in some individuals.
B. Penicillin allergy is not a contraindication for celecoxib. There is no cross-reactivity between penicillin antibiotics and celecoxib, as they are different classes of medications.
C. Concurrent use of chondroitin is not a contraindication for celecoxib. Chondroitin is a dietary supplement commonly used for joint health, and there are no known interactions or contraindications between chondroitin and celecoxib.
D. Concurrent use of calcium supplements is not a contraindication for celecoxib. There are no known interactions between calcium supplements and celecoxib, and they can be safely used together if indicated.
Correct Answer is A
Explanation
A. Furosemide can decrease the renal clearance of lithium, leading to increased lithium levels in the blood. This can potentiate the toxic effects of lithium, such as neurotoxicity and cardiac toxicity. Therefore, concurrent use of furosemide and lithium is generally contraindicated, and caution is advised. The nurse should identify lithium carbonate as contraindicated in this scenario.
B. Albuterol is a bronchodilator commonly used to treat respiratory conditions such as asthma and chronic obstructive pulmonary disease (COPD). There are no significant contraindications between albuterol and furosemide.
C. Levothyroxine is a synthetic thyroid hormone used to treat hypothyroidism. There are no significant contraindications between levothyroxine and furosemide.
D. Cetirizine is an antihistamine used to treat allergies and allergic reactions. There are no significant contraindications between cetirizine and furosemide. They are generally considered safe to use together.
