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 D

Explanation

Choice A rationale

Filgrastim (G-CSF) is used to stimulate the production of white blood cells to decrease the risk of infection. A formed bowel movement is unrelated to the specific outcomes of this medication.

Choice B rationale

While filgrastim can improve overall blood cell counts, its primary goal is to enhance neutrophil counts, rather than addressing skin petechiae or purpura, which may be related to platelet levels.

Choice C rationale

Filgrastim does not target gastrointestinal symptoms such as nausea. Instead, it is aimed at restoring neutrophil levels to reduce infection risk.

Choice D rationale

Filgrastim is specifically designed to increase neutrophil counts, thus helping the patient to be free from infections by discharge, which is a SMART goal.

A. Tumor lysis syndrome (TLS). B. Hypercalcemia. C. Spinal cord compression. D. Superior vena cava syndrome (SVCS).

Correct Answer is D

Explanation

Choice A rationale

Tumor lysis syndrome (TLS) results from the rapid breakdown of cancer cells, leading to metabolic imbalances such as hyperuricemia, hyperkalemia, hyperphosphatemia, and hypocalcemia. Symptoms can include nausea, vomiting, diarrhea, muscle cramps, and arrhythmias. TLS is a metabolic emergency seen in high-turnover cancers like leukemia or lymphoma and is not associated with symptoms like jugular venous distention or edema in the face, neck, and arms.

Choice B rationale

Hypercalcemia, often due to bone metastasis or certain paraneoplastic syndromes, presents with symptoms such as confusion, lethargy, constipation, nausea, polyuria, and polydipsia. It is not related to the symptoms described in the question, which are indicative of a different oncologic emergency.

Choice C rationale

Spinal cord compression occurs when a tumor compresses the spinal cord, leading to symptoms like severe back pain, weakness, sensory changes, and autonomic dysfunction. It does not explain the symptoms of jugular venous distention, facial, neck, and arm edema.

Choice D rationale

Superior vena cava syndrome (SVCS) occurs when a tumor compresses the superior vena cava, leading to decreased venous return from the upper body. Symptoms include shortness of breath, jugular venous distention, and edema of the face, neck, and arms due to impaired blood flow. This is an oncologic emergency requiring prompt intervention to reduce the obstruction.
