Which is a result of consuming a diet deficient in iodine?
Group of answer choices
low plasma concentration of thyroid hormones due to reduced secretion of thyroid-stimulating hormone (TSH) by the pituitary gland
low plasma concentration of thyroid hormones and an enlarged thyroid gland
high plasma concentration of thyroid-stimulating hormone (TSH) due to a deficiency of thyrotropin-releasing hormone (TRH)
high plasma concentration of thyroid hormones due to increased secretion of TSH by the pituitary gland
low plasma concentration of thyroid hormones and atrophy of the thyroid gland due to reduced concentrations of thyroid-stimulating hormone (TSH)
Which of the following statements best describes diseases of the thyroid gland?
Hyperthyroidism is associated with increased metabolism driven by increased sympathetic nervous drive.
Children with cretinism have elevated levels of thyroid hormones and catecholamine-induced tachycardia.
Hashimoto’s disease is more common in men than women and is associated with a goitre and unexplained weight gain.
Grave’s disease is associated with overproduction of antibodies that cause the destruction of the thyroid gland.
A goitre is an enlargement of the thyroid gland, resulting in a large swelling of the neck. It can lead to swallowing or breathing problems. It is most commonly caused by inadequate amounts of dietary iodine. Iodine is essential in thyroxine synthesis. Enlargement of the thyroid gland occurs
Select one:
a. due to decreased levels of TSH
b. due to increased levels of thyroxine
c. due to decreased levels of thyroxine
d. due to increased levels of TSH

- Figure 16.14 Goiter, a disease caused by iodine deficiency, results in the inability of the thyroid gland to form T3 and T4 . The body typically attempts to compensate by producing greater amounts of TSH. Which of the following symptoms would you expect goiter to cause? a. Hypothyroidism, resulting in weight gain, cold sensitivity, and reduced mental activity. b. Hyperthyroidism, resulting in weight loss, profuse sweating and increased heart rate. C. Hyperthyroidism, resulting in weight gain, cold sensitivity, and reduced mental activity. d. Hypothyroidism, resulting in weight loss, profuse sweating and increased heart rate.arrow_forwardThe symptoms of Cushing’s disease include abdominal obesity, hypertension, glucose intolerance (steroid diabetes), hirsutism, osteoporosis, polyuria, and polydipsia. Describe the consequences of cortisol excess that would produce each of these symptoms. Which tests can be performed to determine if a patient has primary or secondary Cushing’s disease? What would the results of these tests be for each type of disease?arrow_forwardPlease specify how hyperthyroidism and hypothyroidism occur. Why is the iodine important for homeostasis? What is the appropriate drugs to treat hyperthyroidism and hypothyroidism among the below drugs: Peroxidine: A drug that inhibits thyroid peroxidase from functioning Cimigine: A drug that inhibits potassium/iodine cotransporter Iodimine: A drug that inhibits iodinase from functioning Aldosine: A drug that inhibits production of angiotensinogen from the liver Aldoramine: A drug that inhibits sodium/iodine cotransporter Thyromine: A drug that stimulates thyroglobulin production Thank you,arrow_forward
- Thyroid cancer results when the cells in the thyroid gland divide uncontrollably. Individuals who have excessive exposure to radiation may have higher chance of getting thyroid cancer. Thyroid cancer can be treated through surgery, iodine therapy, radiotherapy, and/or chemotherapy. What is the purpose of prescribing thyroxine medication for patients following the surgical removal of the thyroid gland? Select one: a. to decrease TRH and increase TSH levels b. to increase TRH and TSH levels c. to decrease TRH and TSH levels d. to increase TRH and decrease TSH levelsarrow_forwardA person develops a rare autoimmune condition during early adulthood which targets only the cells in the thyroid responsible for the release of calcitonin. Which of the following is most likely to describe the patient's blood Ca2+ concentration? This person is asymptomatic and has normal blood Ca" levels. This person has hypocalcemia (low blood Ca) because osteoclasts are not resorbing bone. This person has hypocalcemia (low blood Ca) because of reduced Ca absorption in the gastrointestinal tract This person has hypercalcemia (high blood Ca) because osteoblasts are not depositing bone.arrow_forwardExplain the reasons why each of these signs and symptoms happen in Hyperthyroidism and Hypothyroidism.

- Elaine’s doctor recommends supplementing her lifestyle changes with medication. Which of the following statements is true regarding diabetes treatment? Diabetes Mellitus Type II is always treated with insulin injections. For patients with insulin resistance, medication to increase cell sensitivit can reverse the problem. Medication to stop the pancreas from producing insulin is effective. Even though Elaine's symptoms are mild, her doctor will recommend a permanent insulin pump because of her age.arrow_forwardThe endocrine system is composed of glands that secrete hormones that regulate the activity of different body cells. The pituitary gland is often called the "master gland" because it controls the activities of other glands. Discuss a disorder associated with either hypo or hypersecretion of a specific hormone secreted by the pituitary gland. Include in your discussion the answer to the following: What effect will an increase or decrease in production have on the target organs?What signs and symptoms are associated with this condition and how is it treated?arrow_forwardHypertension is common and most often presents as an independent medical condition. Occasionally, hypertension is a result of an underlying illness and requires different treatment. Because adrenal function is critical for (1) blood pressure, (2) potassium, and (3) glucose homeostasis, an adrenal etiology should be considered in all patients with blood pressure problems accompanied by electrolyte abnormalities, unexplained change in weight, failure to thrive, inappropriate virilization, and anxiety periods. Eight different clinical scenarios are presented below. Each presentation is associated with a different diagnosis and treatment. A discussion of adrenal causes, diagnoses, and treatments for each is found within the chapter. Each numbered case study completes the following opening statement: A 22-year-old woman (previously adopted, not currently taking medications, negative medical history) presents with hypertension, with weakness and rapid onset of obesity.
