Q1 QUESTION 1 OF 264
Signs and symptoms of hypothyroidism
CORRECT ANSWER
Face is pale, puffy, and expressionless.
Skin is cold and dry.
hair is brittle, and hair loss occurs.
Heart rate and temperature are lowered. The patient lethargy, fatigue, and intolerance to cold.
Mentation may be impaired.
RATIONALE
Hypothyroidism results in reduced metabolic activity due to insufficient thyroid hormone levels, leading to characteristic manifestations such as
pale, puffy skin, cold intolerance, lethargy, and bradycardia. These signs reflect the systemic effects of decreased metabolism on various organ
systems and energy expenditure.
Q2 QUESTION 2 OF 264
Signs and symptoms of hyperthyroidism
CORRECT ANSWER
Heart Rate is Rapid; Possible arrhythmia/angina
Nervousness, insomnia, rapid thought flow, and rapid speech
Skeletal muscles may weaken and atrophy
Metabolic rate is raised, resulting in increased heat production, increased body temperature, intolerance to heat, and skin that is warm
and moist
Weight loss occurs if caloric intake fails to match the increase in metabolic rate
RATIONALE
Hyperthyroidism accelerates the metabolic rate through elevated thyroid hormone levels, leading to symptoms such as tachycardia, anxiety, and
heat intolerance, while muscle atrophy can occur due to protein catabolism. This condition reflects the body's heightened energy demands,
resulting in weight loss if caloric intake does not compensate.
Q3 QUESTION 3 OF 264
Severe hypothyroidism
CORRECT ANSWER
Myxedema
RATIONALE
Myxedema results from severe hypothyroidism, characterized by the accumulation of glycosaminoglycans in the dermis, leading to a thickened,
non-pitting edema. This condition reflects the systemic effects of insufficient thyroid hormone, impacting metabolism and fluid balance.

, Q4 QUESTION 4 OF 264
Hypothyroid Treatment
CORRECT ANSWER
Levothyroxine is the drug of choice for most patients who require thyroid hormone replacement.
RATIONALE
Levothyroxine, a synthetic form of thyroxine (T4), effectively normalizes thyroid hormone levels and is preferred due to its predictable
pharmacokinetics and ability to mimic the body's natural hormone production. This aligns with the principle of hormone replacement therapy,
ensuring adequate metabolic regulation in hypothyroid patients.
Q5 QUESTION 5 OF 264
Levothyroxine (Synthroid) Therapeutic Goal
CORRECT ANSWER
Resolution of signs and symptoms of hypothyroidism and restoration of normal laboratory values for serum thyroid-stimulating hormone
(TSH) and free thyroxine (T4).
RATIONALE
Achieving resolution of hypothyroid symptoms and normalizing serum TSH and free T4 levels indicates effective thyroid hormone replacement
therapy, demonstrating the restoration of metabolic homeostasis. Monitoring these parameters ensures that levothyroxine dosage is adjusted
to meet the physiological needs of the patient.
Q6 QUESTION 6 OF 264
Major forms of hyperthyroidism
CORRECT ANSWER
Graves disease and toxic nodular goiter (also known as Plummer disease).
RATIONALE
Graves disease results from autoimmune stimulation of the thyroid gland, leading to excessive hormone production, while toxic nodular goiter
involves autonomous hyperfunctioning nodules. Both conditions are primary causes of hyperthyroidism, characterized by elevated thyroid
hormone levels and associated clinical manifestations.
Q7 QUESTION 7 OF 264
Graves Disease
CORRECT ANSWER
Most common cause of excessive thyroid hormone secretion
Page 3
, RATIONALE
Graves disease is characterized by autoimmune stimulation of the thyroid gland, leading to hyperplasia and excessive production of thyroid
hormones, primarily thyroxine (T4) and triiodothyronine (T3). This condition exemplifies the pathophysiological principle of hyperthyroidism
driven by autoantibodies against the thyroid-stimulating hormone receptor.
Q8 QUESTION 8 OF 264
What adjunctive therapy is good to prescribe to control symptoms of hyperthyroidism other than thyroid specific medications?
CORRECT ANSWER
β-Blockers and nonradioactive iodine may be used as adjunctive therapy.
β-Blockers suppress tachycardia by blocking β-receptors on the heart.
Nonradioactive iodine inhibits synthesis and release of thyroid hormones.
RATIONALE
β-Blockers effectively manage hyperthyroid symptoms like tachycardia by antagonizing β-adrenergic receptors, thereby reducing heart rate and
anxiety. Nonradioactive iodine serves as an adjunct by inhibiting thyroid hormone synthesis and release, providing symptomatic relief while
awaiting more definitive treatments.
Q9 QUESTION 9 OF 264
Hyperthyroid Treatment
CORRECT ANSWER
thionamide drugs—methimazole and propylthiouracil (PTU)—suppress synthesis of thyroid hormones.
RATIONALE
Thionamide drugs, such as methimazole and propylthiouracil, inhibit thyroid peroxidase, thereby reducing the synthesis of thyroid hormones
and effectively managing hyperthyroidism. This mechanism directly addresses the overproduction of hormones characteristic of the condition.
Q10 QUESTION 10 OF 264
Methimazole Therapeutic Goal
CORRECT ANSWER
(1) reduction of thyroid hormone production in Graves' disease, (2) control of hyperthyroidism until the effects of radiation on the thyroid
become manifest, (3) suppression of thyroid hormone production before subtotal thyroidectomy, (4) treatment of thyrotoxic crisis.
RATIONALE
Methimazole inhibits thyroid peroxidase, reducing the synthesis of thyroid hormones, making it pivotal in managing hyperthyroidism due to
Graves' disease and preparing patients for surgical intervention or radioactive iodine therapy. This medication effectively controls excessive
hormone levels, mitigating symptoms and preventing complications associated with thyrotoxicosis.
