The nurse is caring for a patient who has a new prescription for levothyroxine.
The nurse will include in the teaching plan that levothyroxine decreases the action of which medication?

Metformin.

Warfarin.

Sertraline.

Methylprednisolone.

Answer and Explanation

The Correct Answer is B

Choice A rationale

Metformin is used to manage diabetes, primarily by improving insulin sensitivity and reducing glucose production in the liver. Levothyroxine, used to treat hypothyroidism, does not significantly impact the action of metformin. The two medications do not have a direct interaction that decreases metformin's efficacy.

Choice B rationale

Levothyroxine can decrease the action of warfarin by increasing the metabolism of clotting factors in the liver, which may reduce the anticoagulant effect of warfarin. This interaction necessitates closer monitoring of INR (International Normalized Ratio) levels and potential dose adjustments of warfarin to maintain its therapeutic effect.

Choice C rationale

Sertraline is an antidepressant that belongs to the selective serotonin reuptake inhibitor (SSRI) class. While it can interact with other medications, levothyroxine does not significantly decrease its action. Therefore, no major adjustments are needed when both drugs are prescribed together.

Choice D rationale

Methylprednisolone, a corticosteroid, is used for its anti-inflammatory and immunosuppressant properties. Levothyroxine does not decrease the action of methylprednisolone. These medications do not have a significant pharmacological interaction that would require adjusting methylprednisolone’s dosage.

Correct Answer is B

Explanation

Choice A rationale

Chemotherapy and radiation can significantly affect fertility. It would be incorrect to reassure the patient that these treatments will not impact her ability to become pregnant, as these treatments often reduce fertility or cause temporary or permanent infertility.

Choice B rationale

Discussing fertility counseling and contraception options allows the patient to make informed decisions about her reproductive health. Fertility preservation methods, such as egg or embryo freezing, can be considered before starting treatment. This approach respects the patient's desire to become pregnant while acknowledging the impact of cancer treatment.

Choice C rationale

Referring the patient to a social worker for pregnancy surrogacy is premature and not directly addressing the patient's immediate concerns about fertility and treatment. Fertility counseling is a more appropriate initial step.

Choice D rationale

Delaying treatment for cancer to allow for pregnancy can have severe negative impacts on the patient's prognosis and is not advised. Immediate treatment is crucial to control the disease and improve survival chances.

A. The nurse must wear a dosimeter badge when preparing and administering chemotherapy infusions. B. The patient should wear a lead apron during chemotherapy infusions. C. The nurse must wear personal protective equipment (PPE), including gloves and a gown when handling chemotherapy. D. The nurse must dispose of all chemotherapy waste in the patient's sharps container.

Correct Answer is C

Explanation

Choice A rationale

Wearing a dosimeter badge is essential for healthcare workers handling radioactive materials to monitor exposure, but it is not a standard practice for handling chemotherapy, which is typically not radioactive. Chemotherapy drugs are cytotoxic and require different safety measures, such as PPE.

Choice B rationale

While protecting patients during radiation therapy with a lead apron is necessary, it is not applicable for chemotherapy infusions. Chemotherapy involves the administration of cytotoxic drugs, not ionizing radiation, so protective measures focus on preventing exposure to these chemicals rather than shielding from radiation.

Choice C rationale

The nurse must wear personal protective equipment (PPE), including gloves and a gown, when handling chemotherapy to prevent exposure to these toxic drugs. PPE is crucial to protect healthcare workers from accidental spills, splashes, and skin contact with the chemotherapy agents, which can be harmful.

Choice D rationale

Disposal of chemotherapy waste should follow specific guidelines to prevent contamination and exposure. Sharps containers are for sharp objects like needles and blades, not for all chemotherapy waste. Chemotherapy waste should be disposed of in designated containers that comply with hazardous waste regulations to ensure safe handling and disposal.
