Potential ADE include GI upset. 47. **Know how to interpret lab values for hypo and hyperthyroidism** Hypothyroidism - Thyroid-Stimulating Hormone (TSH): Elevated. TSH is produced by the pituitary gland and stimulates the thyroid to produce thyroid hormones3. When thyroid hormone levels are low, the pituitary produces more TSH to stimulate the thyroid. - Thyroxine (T4): Low. T4 is one of the main hormones produced by the thyroid3. - Free T4 (FT4): Low. This is the portion of T4 that is not bound to proteins and is available to enter tissues3. - Triiodothyronine (T3): Low. T3 is the active form of thyroid hormone4. Hyperthyroidism - Thyroid-Stimulating Hormone (TSH): Low. When thyroid hormone levels are high, the pituitary produces less TSH3. - Thyroxine (T4): High. T4 levels are elevated in hyperthyroidism4. - Free T4 (FT4): High. This indicates an excess of unbound T43. - Triiodothyronine (T3): High. T3 levels are elevated in hyperthyroidism4. 48. **Know MOA for Levothyroxine** Synthetic form of the T4 produced by the body. Will restore thyroid hormone levels in body. 49. **Differentiate between hypothyroidism, hyperthyroidism, euthyroidism and subclinical hypothyroidism**A table of medical information Description automatically generated with medium confidence Hypothyroidism - Definition: A condition where the thyroid gland is underactive, producing insufficient thyroid hormones. - Symptoms: Fatigue, weight gain, cold intolerance, dry skin, and increased risk of heart problems(Drugda et al., 2023). - Biochemical Markers: Low levels of thyroxine (T4) and elevated thyroid-stimulating hormone (TSH) levels(Drugda et al., 2023). Hyperthyroidism - Definition: A condition characterized by an overactive thyroid gland, producing excessive thyroid hormones. - Symptoms: Weight loss, heat intolerance, increased appetite, and anxiety. It may also present with myxedema, a condition typically associated with hypothyroidism(Sciacchitano et al., 2024). - Biochemical Markers: Elevated levels of thyroid hormones (T3 and T4) and suppressed TSH levels(Hirano et al., 2024). Euthyroidism - Definition: A state of normal thyroid function where the thyroid gland produces adequate amounts of hormones. - Biochemical Markers: Normal levels of thyroid hormones and TSH, indicating balanced thyroid function(Sciacchitano et al., 2024). Subclinical Hypothyroidism - Definition: A mild form of hypothyroidism where TSH levels are elevated, but thyroid hormone levels remain within the normal range(Jassim & Al-Jubory, 2024) (Drugda et al., 2023). - Symptoms: Often asymptomatic, but can be associated with an increased risk of coronary heart disease(Drugda et al., 2023). - Prevalence and Management: Commonly diagnosed in older adults, with spontaneous normalization in many cases. Treatment is debated, especially in the elderly, due to potential overtreatment risks(Ruderich & Feldkamp, 2022). 50. **Monitoring hypothyroidism treatment** Checking TSH every 6-8 weeks 51. **Dosing hypothyroidism medication in special populations such as elderly and pregnancy** Pediatrics l.

It is less commonly used today but still prescribed in some cases. 54. **Know therapeutic lab values for thyroid** TSH (mU/L)\*\* \| 0.4 - 4.5 Free T4 (ng/dL)\*\*\| 0.9 - 2.3 Total T4 (µg/dL)\*\*\| 5.0 - 11.0 Free T3 (pg/mL)\*\*\| 2.3 - 4.2 55. **Know the symptoms of hypothyroidism and hyperthyroidism** Hypothyroidism (Underactive Thyroid) - Fatigue - Weight gain despite a normal diet - Cold intolerance - Dry skin and hair loss - Constipation - Depression and mood swings - Muscle weakness and joint pain - Memory problems and difficulty concentrating - Hoarseness of voice - Puffy face Hyperthyroidism (Overactive Thyroid) - Weight loss despite an increased appetite - Heat intolerance - Increased sweating - Nervousness and anxiety - Rapid or irregular heartbeat (palpitations) - Tremors (shaking hands) - Frequent bowel movements or diarrhea - Muscle weakness - Sleep disturbances - Fine, brittle hair and hair loss - Changes in menstrual patterns 56. **What medication do you use to manage hyperthyroidism** Antithyroid drugs methimazole and propylthiouracil Beta-blockers to help with cardiac effects while waiting for ATD to take effect Iodine comppounds 57. **What is a thyroid storm** Thyroid storm is a life-threatening condition that results from severe thyrotoxicosis. Triggers include infection, trauma, thyroidectomy, RAI treatment, and abrupt discontinuation of anti-thyroid medications. The clinical presentation of thyroid storm includes signs and symptoms seen in hyperthyroidism but intensified. Treatment is aggressive and requires admission to the intensive care unit.
