A nurse is planning to provide community education about viral hepatitis. Which of the following should the nurse plan to include in the teaching?

A. The water seal chamber should contain at least 2 cm of water to maintain the seal and prevent air from entering the pleural space. Only 1 cm of water is inadequate and requires intervention.
B. Tidaling, or fluctuation of water with respirations, is an expected finding and indicates that the system is functioning properly.
C. A suction chamber pressure of -20 cm H₂O is the standard setting for chest tube drainage systems and does not require intervention.
D. A drainage collection chamber that is one-third full is within normal limits and simply indicates the need to continue monitoring output.

A. Levothyroxine is a medication used to treat hypothyroidism by replacing or supplementing thyroid hormone. It is not typically associated with decreased blood pressure.

B. Weight loss can be an indicator that levothyroxine therapy is effective in treating hypothyroidism. Hypothyroidism often leads to weight gain, and successful treatment with levothyroxine can help reverse this trend.

C. Levothyroxine therapy primarily targets thyroid hormone levels and is not directly associated with decreased inflammation.

D. Seizures are not typically associated with hypothyroidism or its treatment with levothyroxine.

The effectiveness of levothyroxine is primarily assessed by monitoring thyroid function tests and clinical symptoms such as weight loss, improved energy levels, and resolution of hypothyroid symptoms.
