Answer:
1. Levothyroxine is a synthetic hormone medication used to replace the naturally produced hormone, thyroxine (T4), which is solely responsible for regulating metabolism.
2. The most common side effects of levothyroxine include headache, nausea, vomiting, appetite changes, hair loss, and insomnia.
3. In this case, the elevated blood pressure (BP 160/148) can be attributed to the levothyroxine as the patient is taking this in addition to the metoprolol (Toprol 50 mg) for hypertension. Additionally, her behavior (shouting before apologizing) could also be attributed to the levothyroxine as one of the side effects is insomnia which can cause irritability, fatigue, and difficulty concentrating.
4. With this information, you should take note of the side effects of levothyroxine and be aware that the patient is taking two medications to control her hypertension. Encourage her to get a good night's sleep before the surgery so she is rested and in a better mental state for the procedure.
