==Question 2==
A client takes levothyroxine for hypothyroidism. Which statement by the client indicates a need for further teaching?
# "I take it first thing in the morning with a full glass of water."
# "I wait at least 30 minutes after taking it before I eat breakfast."
# "I take my calcium supplement at the same time so I do not forget either one."
# "I know I will need to take this medication for the rest of my life."

'''Answer:''' 3 (C) "I take my calcium supplement at the same time so I do not forget either one."

''Rationale:'' Calcium, along with iron and antacids, binds levothyroxine and markedly reduces its absorption, so these should be separated by about 4 hours. Options 1, 2, and 4 all reflect correct understanding: levothyroxine is taken in the morning on an empty stomach, food is delayed at least 30 to 60 minutes, and therapy is usually lifelong.
