Without the specific content of the question or answer, it's impossible to provide a tailored rationale. Please provide the relevant
details for accurate assistance.
Q2 QUESTION 2 OF 170
Thyroid
o Diagnosis & Evaluation
What labs are used to diagnose?
CORRECT ANSWER
-TSH - used primarily for screening and diagnosing hypothyroid and for monitoring replacement therapy in hypothyroid patients
-T4 - Used to monitor thyroid hormone replacement therapy and to screen for thyroid dysfunction
-T3 - Useful in the diagnosis of hyperthyroidism; can also be used to monitor hormone replacement therapy
-TSH low
-T4 normal
-T3 is high = hyperthyroidism
RATIONALE
Thyroid function tests, primarily TSH, T4, and T3, assess hormone levels to diagnose hypothyroidism or hyperthyroidism, with TSH
being the initial screening tool; a low TSH coupled with high T3 indicates hyperthyroidism, reflecting the negative feedback
mechanism of thyroid hormone regulation. Monitoring these hormones is crucial for adjusting replacement therapy and evaluating
thyroid dysfunction.
Q3 QUESTION 3 OF 170
Thyroid
o Diagnosis & Evaluation
Timeframe for re-check of labs after starting levothyroxine?
CORRECT ANSWER
Recheck TSH 6-8 weeks after initiating therapy and after any dosage change; Check TSH at least once a year after serum TSH is
stabilized
Page 2
, RATIONALE
Levothyroxine therapy requires monitoring of thyroid-stimulating hormone (TSH) levels to ensure adequate dosing and to avoid under-
or overtreatment, with a recommended interval of 6-8 weeks for initial checks following therapy initiation or dosage adjustments.
Once TSH levels stabilize, annual evaluations are sufficient to maintain appropriate thyroid function.
Q4 QUESTION 4 OF 170
Thyroid
o Diagnosis & Evaluation
Signs and symptoms of hypothyroidism?
CORRECT ANSWER
Hypothyroidism: Depend on severity.
o Mild: subtle and may go unrecognized
o Moderate to severe:
-Face is pale, puffy, and expressionless.
-Skin cold and dry.
-Hair is brittle and hair loss occurs.
-Slowed Heart rate.
-Patient may complain of lethargy, fatigue, and
-Temperature is lowered & intolerant to cold.
-Thyroid Enlargement may occur if reduced levels of T3
and T4
Mentation may be impaired.
RATIONALE
Hypothyroidism leads to a decrease in metabolic processes due to insufficient levels of thyroid hormones, resulting in symptoms such
as lethargy, cold intolerance, and bradycardia. These manifestations reflect the body's inability to maintain homeostasis and energy
balance, highlighting the condition's impact on multiple physiological systems.
Q5 QUESTION 5 OF 170
Thyroid
o Diagnosis & Evaluation
Signs and symptoms of hyperthyroidism?
CORRECT ANSWER
o Elevated Heart rate and strong, and dysrhythmias and angina may develop
o The CNS is stimulated, resulting is nervousness, insomnia, rapid thought flow, and rapid speech, hyperreflexia, tremors
o Skeletal muscles may weaken and atrophy
o Metabolic rate is raised, resulting in health and skin that is warm and moist
o Feeling Hot + Heat intolerance
o Appetit is increased but fails to match metabolic rate resulting in weight loss
o All of these signs are referred to as thyrotoxicosis
o Also usually present with exophthalmos - bulging of the eyes
Page 3
, RATIONALE
Elevated heart rate, nervousness, and heat intolerance are manifestations of increased sympathetic nervous system activity and
heightened metabolic rate in hyperthyroidism, collectively termed thyrotoxicosis. This condition results in a range of physiological
changes, including muscle atrophy and weight loss due to an imbalance between caloric intake and metabolic demands.
Q6 QUESTION 6 OF 170
Thyroid
o Treatment
Treatment of thyroid storm?
CORRECT ANSWER
Characterized by profound hyperthermia (105 degrees F or higher), severe tachycardia, restlessness, agitation, and tremor.
Unconsciousness, coma, hypotension, and heart failure may ensure.
These symptoms are produced by excessive levels of thyroid hormone
Thyroid crisis can be life threatening and requires immediate treatment.
o High doses of potassium iodide or strong iodine solution are given to suppress thyroid hormone release.
o Methimazole is given to suppress thyroid hormone synthesis
o A beta blocker is given to reduce heart rate
o Additional measures include sedation, cooling, and giving
glucocorticoids and IVF
RATIONALE
High doses of potassium iodide or strong iodine solution inhibit the release of thyroid hormones by saturating the thyroid gland, while
methimazole effectively blocks hormone synthesis, addressing the life-threatening hypermetabolic state of thyroid storm. These
interventions, alongside beta blockers to manage tachycardia and supportive measures like sedation and cooling, are critical in
mitigating severe symptoms and preventing complications.
Q7 QUESTION 7 OF 170
Thyroid
o Treatment
Result of not treating hypothyroidism during pregnancy?
CORRECT ANSWER
Can result in permanent neuropsychological deficits in the child - decrease child's IQ
The effect of hypothyroidism is limited largely to the first trimester, a time during which the fetus is unable to produce thyroid
hormone of its own
Some authorities currently recommend routine screening for hypothyroidism as soon as pregnancy is confirmed
Women already taking thyroid hormone replacement will need to increase dose by 50% max between weeks 4-8 of gestation and
the levels will level out by week 16
