The nurse is planning health teaching for a patient starting on Levothyroxine. What health teaching about this drug would the nurse include?

Choice A reason: While monitoring pulse is important, daily blood pressure checks are not routinely required unless the patient has comorbid hypertension. Choice B reason: Levothyroxine is administered orally, not by injection, so rotating injection sites is irrelevant. Choice C reason: Chest pain and dyspnea may indicate cardiac side effects or overtreatment, especially in older adults or those with cardiac disease. These symptoms must be reported immediately. Choice D reason: Levothyroxine should be taken consistently in the morning on an empty stomach, not based on symptoms like fatigue.
