Q

What is thyroid scanning?

A

It determines whether the growth is solid or filled with fluid. Helps determine whether the functioning of a specific area of the thyroid is normal, overactive, or underactive.

Q

What is a radioactive iodine uptake test?

A

It is when a small amount of a radioactive substance is injected into the bloodstream. The thyroid gland becomes concentrated and a gamma camera does another type of scan that will detect the radiation and produce a picture of the gland

Q

What are some symptoms of Graves disease?

A
  1. Bulging eyes due to inflammation of the orbits behind the eyes.
  2. Double vision (diplopia) do to the muscles having difficulty move the eyes normally or to coordinate eye movements
22
Q

A
  1. Antithyroid medication
  2. Beta-blockers
  3. Iodine
  4. Radioactive iodine therapy
    5, Surgery
23
Q

What do antithyroid medications do?

A

They reduce TH production. Most common types are methiamozole and propylthiouracil

24
Q

How do beta-blockers help with the thyroid?

A

May be given to decrease cardiovascular symptoms and help control the symptoms of hyperthyroidism

25
Q

Why is iodine given to people with hyperthyroidism?

A

They may need rapid treatment such as those in a thyroid storm or until the patient can get a thyroidectomy. It is not for long term use and it is given orally

26
Q

When given orally, when are results from radioactive iodine therapy typically seen?

A

After 6-8 weeks

27
Q

What are patients taught to do if they have radioactive iodine therapy done?

A

Measure their pulse rate and notify their doctor if it exceed 100 bpm following therapy until released stores of TH diminish

28
Q

After radioactive iodine treatment, how long should the patient stay away from infants and children, and what should they do if they have a partner?

A
  1. Stay away from children and infants for at least 2-4 days. Pregnancy should be avoided for 6 months
  2. Sleep in a separate bed at least 6 feet apart from their partner
29
Q

What should patients be aware of if they go to an airport after having radioactive iodine treatments done?

A

The may set off radiation alarms at airports and other places several weeks after treatment. They should carry a doctor’s note describing their treatment when traveling.

30
Q

What should the patient be given before a thyroidectomy?

A

Antithyroid drugs to reduce hormone levels and iodine preparations to decrease the vascularity and size of the gland

31
Q

What rare complications can occur for someone who has a thyroidectomy?

A

paralysis of vocal cords and damage to the parathyroid glands

32
Q

After the thyroidectomy what needs to be monitored?

A

Calcium levels need to monitored for hypocalcemia that can cause neuromuscular irritability

33
Q

How does hyperthyroidism manifest itself in pediatric patients?

A

Clinical manifestations are similar to adults. However, it may affect their growth and development

34
Q

What are the lifespan considerations for a pregnant woman with hyperthyroidism?

A
  1. Usually caused by Graves disease and may be caused by hyperemesis gravidarum.
  2. If it is left uncontrolled it can lead to congestive heart failure, preeclampsia, thyroid storm, miscarriage, premature birth, and low birth weight
35
Q

What are the lifespan considerations for newborns with hyperthyroidism?

A
  1. Can result in rapid HR, leading heart failure, early closure of the fontanelles, poor weight gain, irritability, and breathing issues do to an enlarged thyroid gland that presses against the trachea.
  2. If the mother has been treated with antithyroid medication, fetal hyperthyroidism is less likely because the drug crosses the placenta
36
Q

What are the lifespan considerations of older adults with hyperthyroidism?

A
  1. Toxic goiter is more frequent
  2. May only have 1 or 2 symptoms
  3. surgery is rarely recommended because of increased surgical risks
37
Q

What are the causes of hypothyroidism?

A
  1. hashimoto thyroiditis (they gland is gradually being destroyed)
  2. Thyroid inflammation
  3. Lack of IODINE
  4. Radiation to the head and neck
  5. Inherited disorders that prevent the thyroid gland from making or secreting enough hormones
38
Q

What is a secondary cause of hypothyroidism?

A

The pituitary gland fails to secrete enough TSH

39
Q

Describe myxedema coma

A
  1. life-threatening
  2. slowed breathing
  3. decreased blood flow to the brain
  4. Triggered in a person with hypothyroidism by a physical stress like exposure to cold, infection, injury, surgery, and sedatives
  5. dry, course, and sparse hair
  6. Lateral eyebrows thin
  7. periorbital edema (swollen under eyes)

40
Q

What are the symptoms of Hashimoto’s disease?

A
  1. Constipation, fatigue, sluggishness, unexplained weight gain
  2. Excessive or prolonged menstrual bleeding, pale dry skin, enlargement of the tongue
  3. Muscle aches, weakness, tenderness, and stiffness
  4. Memory lapses, depression, joint pain and stiffness
  5. Goiter, a puffy face brittle nails, and hair loss
  6. Sensitivity to cold
41
Q

What treatments are typically used for hypothyroidism?

A

Thyroid replacement hormone (levothyroxine gradually increased whn the level of TSH return to normal)
The use of iodized salt has reduced the risk of hypothyroidism in the US

42
Q

What is the test for Bone density?

A

DEXA X-ray

43
Q

Why is the DEXA X-ray used in hospital settings?

A
  1. detects osteoporosis before a fracture occurs
  2. Predicts chances of fracturing in the future
  3. Determines rate of bone loss
  4. Monitors the effects of treatment
44
Q

What treatments are there for osteoporosis?

A
  1. Follow the doctor’s recommendations
  2. Take calcium and vitamin D supplements
  3. Eat dairy and Dark leafy green vegetables
  4. Take prescribed medications
45
Q

How can someone prevent osteoporosis?

A
  1. limit alcohol intake
  2. Walk or job regularly
  3. Stop smoking
  4. Eat dairy products and dark leafy green vegetables daily
  5. Take calcium and Vitamin D Supplements
46
Q

What are the signs and symptoms of osteoporosis?

A
  1. bone pain or tenderness
  2. Fractures with little or not trauma
  3. Loss of height over time
  4. Neck or lower back pain due to fractures
  5. Stooped posture
47
Q

What is the acronym for the risk factors of osteoporosis?

A 
A= Alcohol use
C= Corticosteroid use
C= Calcium low
E= Estrogen low
S= smoking
S= Sedentary lifestyle
48
Q

Why do athletes have an increased risk to get osteoporosis?

A

Those who are especially in sports that emphasize leanness like gymnastics or cross-country can develop this health problems because of decreased nutrition which causes low bone mass and amenorrhea

49
Q

Why do pregnant women sometimes get osteoporosis?

A

If the mother does not eat foods high in calcium, the fetus will draw what it needs from the mother’s bones

50
Q

Why do women who reach menopause often develop osteoporosis?
