Final answer:
The action that indicates the charge nurse needs to do more teaching is ordering nonmedicated eye drops to lubricate the patient's bulging eyes.
Step-by-step explanation:
The action by the new registered nurse (RN) that indicates the charge nurse needs to do more teaching is choice d. The nurse ordering nonmedicated eye drops to lubricate the patient's bulging eyes is not an appropriate action for a patient with a goiter and possible hyperthyroidism. Bulging eyes, known as exophthalmos, are a common symptom of hyperthyroidism, and using nonmedicated eye drops would not effectively address this symptom.
