A client presents with elevations in triiodothyronine (T3) and thyroxine (T4) and with normal thyroid-stimulating hormone (TSH) levels. Which is the nurse's priority intervention?
a. Administer levothyroxine (Synthroid).
b. Administer propranolol (Inderal).
c. Monitor the apical pulse.
d. Assess for Trousseau's sign.
C
The client's laboratory findings suggest that the client is experiencing hyperthyroidism. The in-creased metabolic rate can cause an increase in the client's heart rate, and the client should be monitored for the development of dysrhythmias. Placing the client on a telemetry monitor might also be a precaution. Synthroid is given for hypothyroidism. Propranolol is a beta blocker often used to lower sympathetic nervous system activity in hyperthyroidism. Trousseau's sign is a test for hypocalcemia.
