A nurse is talking with a client who has been taking levothyroxine to treat hypothyroidism.
The nurse should instruct the client to avoid taking which of the following over-the-counter medications within 4 hr of taking levothyroxine?

Choice A rationale:

Spreading the ointment in a 10 cm² (4 in) area is not the recommended method for nitroglycerin ointment application. The ointment should be applied over a 6x inch area in a thin, uniform layer.

Choice B rationale:

Massaging the ointment into the skin is not advised. The ointment should be applied in a thin layer and left to absorb into the skin.

Choice C rationale:

Applying the ointment in a thick layer is not recommended. A thin, uniform layer is sufficient for therapeutic effect.

Choice D rationale:

Covering the administration area with plastic wrap is the correct action. This helps to keep the ointment in place and enhances absorption.

Choice Arationale:

Flaxseed is a rich source of omega-3 fatty acids and can have anti-inflammatory effects. It does not have any known contraindications with SLE.

Choice B rationale:

Glucosamine is often used to support joint health. It is not contraindicated in clients with SLE and may actually provide some benefits in terms of reducing joint pain and stiffness.

Choice C rationale:

Echinacea is an herbal supplement that is often used to boost the immune system. However, in clients with autoimmune disorders like SLE, boosting the immune system can actually exacerbate the disease. Therefore, Echinacea is contraindicated in clients with SLE.

Choice Drationale:

Ginger is a common herbal supplement that is often used for its anti-inflammatory and anti-nausea effects. It does not have any known contraindications with systemic lupus erythematosus (SLE)
