Final answer:
The appropriate nursing action would be to avoid instilling eardrops and to seek further evaluation from a healthcare provider if needed.
Step-by-step explanation:
The appropriate nursing action in this situation would be to avoid instilling eardrops into the patient's ear. The presence of cerumen (earwax) and discharge of yellow-colored fluid indicates a possible infection or inflammation in the ear. Instilling eardrops may worsen the condition or push the infection deeper into the ear canal.
Instead, the nurse should avoid irrigating the patient's ear and refrain from using cotton buds dipped in mineral oil. These actions can further irritate or damage the ear canal. It is essential to protect the integrity of the ear and prevent any harm.
If the patient is experiencing severe discomfort or pain, the nurse should consult with a healthcare provider for a proper evaluation and treatment plan.
