A patient being treated with medication for a seizure disorder is scheduled for a serum T3 and T4 level. What results should the nurse expect for these levels?
1. falsely reduced
2. falsely elevated
3. normal
4. indicative of pending parathyroid hormone disease
Correct Answer: 1
The value of T3 and T4 blood levels might be decreased by certain medications including phenytoin (Dilantin), which is a medication commonly prescribed for seizure disorders. The levels will not be normal or increased. Measurement of T3 and T4 levels is not indicative of parathyroid disease.
