The nurse is caring for a patient who is scheduled for thyroid diagnostic testing.
Which information, that may affect the test results, should be documented on the patient's electronic medical record (EMR) and communicated to the personnel conducting the test?

The patient is currently taking estrogen replacement.

The patient has a sensitivity to lactose.

The patient is currently taking anti-seizure medication.

The patient frequently eats kelp or seaweed.

Answer and Explanation

The Correct Answer is D

Choice A rationale

Estrogen replacement therapy can have various effects on the body but does not significantly impact thyroid diagnostic tests. This information is still relevant for the patient's overall medical care but not directly related to thyroid testing results.

Choice B rationale

Lactose sensitivity is important for dietary considerations but does not affect thyroid diagnostic tests. Documenting dietary restrictions is important for patient care but does not impact the specific diagnostic tests for thyroid function.

Choice C rationale

Anti-seizure medications can affect thyroid function tests, particularly those that affect the metabolism of thyroid hormones. However, the consumption of iodine-rich foods like kelp or seaweed has a more direct and significant impact on thyroid function and diagnostic testing.

Choice D rationale

Frequent consumption of kelp or seaweed, which are high in iodine, can influence thyroid function tests by altering thyroid hormone levels. This dietary habit should be documented and communicated to ensure accurate interpretation of thyroid function test results. .

Correct Answer is ["675"]

Explanation

Step 1 is (198 ÷ 2.2) × 15 = 1350 mg/day.

Step 2 is 1350 ÷ 2 = 675 mg/dose.

A. Metformin. B. Warfarin. C. Sertraline. D. Methylprednisolone.

Correct Answer is B

Explanation

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.
