ICU for resp/cardiac support, IV thyroid and steroid drugs
What are some nursing implications for radioactive iodine?
Sleep alone for 3-5 nights
Avoid personal contact w/ children for 3-7d
1st 3 days avoid close contact w/ people (6ft), public areas, drink plenty of water, don’t share items, do laundry/dished separate, wipe toilet seat after every use, wash hands frequently, shower daily
Nursing considerations for levothyroxine Synthroid?
Take on empty stomach, 30 min before breakfast,
don’t stop abruptly, take @ same time daily
Decreases effects of antidiabetic meds
Enhances oral anti coagulation
Nursing implications for PTU and Methimazole?
Take w/ meals, don’t stop abruptly,
Take @ same time everyday,
Iodized salt or shellfish can alter effectiveness
