EXAM QUESTIONS
,Q1. Key drugs that can cause hypothyroidism
CORRECT ANSWER
"I TALC"
Interferons
Tyrosine Kinase Inhibitors
Amiodarone
Lithium
Carbamazepine
Conditions: Hashimoto's disease
RATIONALE
These medications are known to cause hypothyroidism as a side effect, often
through mechanisms such as inducing thyroid gland damage, blocking the
conversion of T4 to T3, or interfering with the pituitary-thyroid axis. Hashimoto's
disease is an autoimmune condition that can lead to hypothyroidism, but the listed
medications can also trigger hypothyroidism in susceptible individuals.
Q2. Levothyroxine IV:PO
CORRECT ANSWER
0.75:1 (IV:PO)
RATIONALE
This ratio is correct because it reflects the typical dosing guidelines for
levothyroxine, where the intravenous (IV) dose is approximately one-fourth to one-
third of the oral (PO) dose, allowing for quick correction of severe hypothyroidism
while minimizing the risk of overdose and potential cardiac complications. This
, approach enables healthcare providers to safely and effectively manage
levothyroxine therapy in critically ill patients.
Q3. Full replacement dose levothyroxine
CORRECT ANSWER
1.6 mcg/kg/day (IBW)
If known CAD: start with 12.5-25 mcg daily
RATIONALE
The correct dosage range is based on the American Thyroid Association's (ATA)
levothyroxine replacement guidelines, which take into account the patient's ideal
body weight (IBW) and adjust the dosage for patients with known coronary artery
disease (CAD) to minimize cardiovascular risks. The use of IBW ensures a more
accurate dosage adjustment, while the reduced initial dosage for CAD patients aims
to minimize the risk of exacerbating existing cardiac conditions.
Q4. Levothyroxine tablet colors
CORRECT ANSWER
Orangutans Will Vomit On You Right Before They Become Large Proud Giants
25 Orange
50 White (no dye)
75 Violet
88 Olive
100 Yellow
112 Rose
125 Brown
137 Turquoise
150 Blue
175 Lilac
, 200 Pink
300 Green
RATIONALE
This sequence likely represents a color-coded dosing system for Levothyroxine
tablets, where each color corresponds to a specific dosage strength. The numbers
likely correspond to the dosages in micrograms, with a specific color code assigned
to each unique dosage strength to help patients and healthcare providers easily
identify the correct dosage.
Q5. Drug induced causes of hyperthyroidism
CORRECT ANSWER
Iodine
Amiodarone
Interferons
Radiographic contrast media
RATIONALE
These drugs can cause hyperthyroidism by either directly stimulating the thyroid
gland to produce excess thyroid hormones, or by inducing thyroiditis, a condition
where the thyroid gland becomes inflamed and releases stored hormones into the
bloodstream. Amiodarone, a medication used to treat heart rhythm disorders, is
particularly notable as it can cause both thyroid-stimulating effects and thyroiditis,
leading to hyperthyroidism in some individuals.
