Medical Surgical Thyroid #6

Question

The nurse is providing instruction to a client about iodine for thyroid function. Which food would the nurse recommend as a good source of dietary iodine?

Answers

  1. Shrimp
    • Rationale:

      This answer is correct because good sources of iodine include shrimp, and other shellfish, iodized salt, cheese, cow milk, eggs, yogurt, iodized salt, saltwater fish, seaweed, and cranberries. Too little iodine may cause the body to not make enough thyroid hormone, which may result in iodine deficiency with enlarged thyroid (Goiter) and signs and symptoms of hypothyroidism.

  2. Unsalted peanuts
    • Rationale:

      This answer is not correct because unsalted peanuts is a low source of iodine. If the peanuts were salted with iodized salt, then that would improve the amount of iodine. Good sources of iodine include shrimp, and other shellfish, iodized salt, cheese, cow milk, eggs, yogurt, iodized salt, saltwater fish, seaweed, and cranberries. Too little iodine may cause the body to not make enough thyroid hormone, which may result in iodine deficiency with enlarged thyroid (Goiter) and signs and symptoms of hypothyroidism.

  3. Honey
    • Rationale:

      This answer is not correct because honey is very low in iodine. It provides calories since it is a natural sweetener. Good sources of iodine include shrimp, and other shellfish, iodized salt, cheese, cow milk, eggs, yogurt, iodized salt, saltwater fish, seaweed, and cranberries. Too little iodine may cause the body to not make enough thyroid hormone, which may result in iodine deficiency with enlarged thyroid (Goiter) and signs and symptoms of hypothyroidism.

  4. Canned fruit
    • Rationale:

      This answer is not correct because canned fruit is not a source of iodine. Good sources of iodine include shrimp, and other shellfish, iodized salt, cheese, cow milk, eggs, yogurt, iodized salt, saltwater fish, seaweed, and cranberries. Too little iodine may cause the body to not make enough thyroid hormone, which may result in iodine deficiency with enlarged thyroid (Goiter) and signs and symptoms of hypothyroidism.

Overview

Adequate iodine in the diet is needed for production of thyroid hormones and thyroid function. Nurses should recommend good sources of iodine, including shrimp, and other shellfish, iodized salt, cheese, cow milk, eggs, yogurt, iodized salt, saltwater fish, seaweed, and cranberries.

Explanation

Learning Outcomes

Adequate iodine in the diet is needed for thyroid function. Iodine is an element necessary for the production of thyroid hormone. The body does not manufacture its own iodine, so it must come from a food source. Good sources of iodine include shrimp, and other shellfish, iodized salt, cheese, cow milk, eggs, yogurt, iodized salt, saltwater fish, seaweed, and cranberries. Too little iodine may cause the body to not make enough thyroid hormone, which may result in iodine deficiency with enlarged thyroid (Goiter) and signs and symptoms of hypothyroidism. Symptoms of hypothyroidism include constipation, fatigue, weakness, hair loss, skin dryness, depression, bradycardia, weight gain, sensitivity to cold, and swelling in the extremities.

Test Taking Tip

Knowing several dietary sources for iodine, iron, sodium, and potassium are important because they are commonly tested.
