diagnosed with Addison's disease. The patient has a medical
history positive for type 2 diabetes mellitus and hypertension.
She takes an oral antidiabetic medication and an angiotensin-
converting enzyme (ACE) inhibitor. The health care provider

Case Study
Tommy, a 4-year-old boy, presents to the clinic with short
stature. His height is 85 cm and weight is 14 kg. Upon review of
his history and growth chart, Tommy was average height and
weight at birth; however, there is a marked leveling off and
progressive decline in growth rate around 6 months of age.
,Physical assessment of Tommy reveals an immature face and
overweight body build; the child's proportions remain normal.
Intelligence is normal. Laboratory evaluation demonstrates
growth hormone deficiency. The patient is started on
replacement GH (dose: 40 mcg/kg/day, subcutaneous). After 1
year of GH therapy, his growth rate has significantly increased.

Note:
Thyroid hormone sensitizes the heart to catecholamines
(epinephrine, dopamine, dobutamine) and may produce
dysrhythmias. Correct Answer *Adrenergic drugs such as
epinephrine: increases sympathetic response (heart rate, blood
pressure, possible coronary insufficiency); cardiac medications
may need to be adjusted.
*Oral anticoagulant drugs such as warfarin: increases
anticoagulant effects due to displacement from protein-binding
site. Warfarin dosage may need to be adjusted.
, *Antidiabetic drugs such as insulin or metformin: increases in
blood glucose levels; insulin and noninsulin dosage may need to
be increased.

following points:
-Stress rationale for therapy; remind that response to therapy
may take several months, and that drug therapy is not a cure but
used to manage symptoms.
-Advise to take as prescribed. Stopping antithyroid drug could
bring on thyroid crisis.
-Instruct to take the medication with a meal and limit intake of
iodine rich foods like seafood, seaweed, and iodized salt, which
will decrease drug effectiveness.
