Terms in this Study Set(56)
Hypothyroidism Overview(16)
Define hypothyroidism.
A condition where the thyroid gland does not produce enough thyroid hormones, leading to a slow metabolism.

- Fatigue - Weight gain - Cold intolerance - Dry skin - Constipation
True or False: Hypothyroidism can cause depression.
True. Low thyroid hormone levels can affect mood and lead to depression.
List key features of hypothyroidism.
- Low T3 and T4 levels - Elevated TSH levels - Bradycardia - Myxedema
What nursing action is priority for a hypothyroid patient?
Monitor vital signs and assess for signs of myxedema coma, a severe condition.
Fill in the blank: Hypothyroidism can lead to _____ problems.
Cognitive, due to slowed metabolism and hormone deficiency.
Cause of hypothyroidism?
Autoimmune disorders (e.g., Hashimoto's), iodine deficiency, or certain medications.
What treatments are commonly used for hypothyroidism?
Levothyroxine (synthetic thyroid hormone) is the standard treatment.
How often should TSH levels be monitored in treated patients?
Typically every 6 to 12 months, or as directed by the healthcare provider.
What diet considerations exist for hypothyroid patients?
Adequate iodine intake is essential; avoid excessive soy or cruciferous vegetables that can interfere with function.
Which demographic is most affected by hypothyroidism?
Women, especially those over 60 years old, are more commonly affected.
What is myxedema coma?
A life-threatening condition due to severe hypothyroidism, presenting with extreme cold intolerance, lethargy, and respiratory failure.
True or False: Weight loss is a common symptom of hypothyroidism.
False. Weight gain is more common due to a slower metabolism.
Compare hypothyroidism and hyperthyroidism in terms of energy levels.
Hypothyroidism: Low energy levels. Hyperthyroidism: High energy levels.
What is a common skin manifestation in hypothyroidism?
Dry, coarse skin is a typical presentation.
List two nursing interventions for a patient with hypothyroidism.
- Educate on medication adherence. - Monitor for signs of overdose or underdose.
Hyperthyroidism Overview(16)
What is hyperthyroidism?
A condition where the thyroid gland produces excessive thyroid hormones, leading to increased metabolism.
Key symptom of hyperthyroidism?
Weight loss despite increased appetite.
True or False: Anxiety is a symptom of hyperthyroidism.
True - Anxiety and irritability are common due to increased metabolism.
What is a classic sign of hyperthyroidism?
Exophthalmos (bulging eyes) due to increased tissue around the eyes.
Fill in the blank: Hyperthyroidism can cause ______ heart rate.
an increased heart rate (tachycardia).
Nursing action for a patient with hyperthyroidism?
Monitor vital signs, especially heart rate and blood pressure.
Cause of hyperthyroidism?
Graves' disease, toxic multinodular goiter, or excessive iodine intake.
What is the effect of hyperthyroidism on body temperature?
Increased body temperature, leading to heat intolerance.
Symptoms of hyperthyroidism include:
- Increased sweating - Tremors - Fatigue - Changes in menstrual patterns
Comparing hyperthyroidism and hypothyroidism:
Hyperthyroidism = increased metabolism; Hypothyroidism = decreased metabolism.
Nursing intervention for hyperthyroid patients?
Provide a calm environment to reduce anxiety levels.
What lab test is used to diagnose hyperthyroidism?
TSH (Thyroid Stimulating Hormone) - low levels indicate hyperthyroidism.
What might you find on a physical exam for hyperthyroidism?
Goiter (enlarged thyroid gland) may be present.
True or False: Hyperthyroidism can lead to heart failure.
True - Prolonged tachycardia can lead to heart complications.
Common treatments for hyperthyroidism include:
- Antithyroid medications - Radioactive iodine therapy - Surgery
Nursing priority for hyperthyroidism?
Ensure patient safety and monitor for signs of thyroid storm.
Diagnostic Tests and Values(12)
What is the normal TSH level?
Normal TSH levels range from 0.4 to 4.0 mIU/L. Elevated levels indicate hypothyroidism, while low levels suggest hyperthyroidism.
Free T4 vs Total T4: What's the difference?
Free T4 measures the unbound hormone available for use, while Total T4 includes both bound and unbound. Free T4 is more accurate for thyroid function assessment.
Interpret a T3 level of 200 ng/dL.
A T3 level of 200 ng/dL is typically normal (80-220 ng/dL). High levels indicate hyperthyroidism; low levels can indicate hypothyroidism.
True or False: High TSH indicates hyperthyroidism.
False. High TSH indicates hypothyroidism, while low TSH indicates hyperthyroidism.
What does a thyroid scan assess?
A thyroid scan evaluates the size, shape, and function of the thyroid gland using radioactive iodine.
Cause → Effect: Low iodine intake results in...
...decreased thyroid hormone production, leading to hypothyroidism and potential goiter development.
Normal TRAb (TSH receptor antibodies) level?
Normal TRAb levels are typically less than 1.0 IU/L. Elevated levels indicate Graves' disease.
What lab test is used for autoimmune thyroiditis?
Anti-thyroid peroxidase antibodies (anti-TPO) test. Elevated levels suggest Hashimoto's thyroiditis.
Fill in the blank: A high Free T4 indicates _____.
hyperthyroidism. It means excess hormone is available for metabolism.
What is the significance of a low TSH?
A low TSH indicates hyperthyroidism or pituitary dysfunction, requiring further evaluation.
Normal serum calcium levels?
Normal serum calcium levels range from 8.5 to 10.2 mg/dL. Abnormal levels can indicate thyroid issues.
What is a thyroid function panel?
A thyroid function panel typically includes TSH, Free T4, and Total T3 to evaluate thyroid health.
Patient Education and Management(12)
What dietary changes help hypothyroidism?
Increase iodine intake: - Sea vegetables - Iodized salt - Avoid goitrogens (cabbage, soy) in excess.
True or False: Hyperthyroid patients need to limit calorie intake.
False. Hyperthyroid patients often require increased calorie intake due to elevated metabolism.
Fill in the blank: Take levothyroxine on an empty ___.
stomach, ideally 30-60 minutes before breakfast for optimal absorption.
What are common symptoms of hyperthyroidism?
- Weight loss - Increased heart rate - Heat intolerance - Anxiety.
Cause → Effect: High TSH levels indicate ___
Poor thyroid function, common in hypothyroidism.
How often should thyroid levels be monitored?
Every 6-12 months after stabilization; more frequently if dosage changes.
What is the primary treatment for hypothyroidism?
Levothyroxine (Synthroid) to replace deficient thyroid hormone.
True or False: Patients with hyperthyroidism should avoid caffeine.
True. Caffeine can exacerbate symptoms like anxiety and palpitations.
What lifestyle change is recommended for both conditions?
Regular exercise helps manage weight and improves overall health.
Comparison: Hypothyroidism vs. Hyperthyroidism diet
Hypothyroidism: Iodine-rich foods, Hyperthyroidism: High-calorie foods.
How can stress impact thyroid conditions?
Stress may worsen symptoms, so stress management techniques are essential.
What should patients with thyroid issues avoid?
Excessive soy products and certain cruciferous vegetables in large amounts.
