Final answer:
A nurse would recommend over-the-counter pain relievers for a child experiencing discomfort after a myringotomy with tympanostomy tube insertion.
Step-by-step explanation:
If a child who has undergone a myringotomy with insertion of tympanostomy tubes is experiencing discomfort, the nurse advises the mother to administer over-the-counter pain relievers. These pain relievers can help alleviate the ear pain (otalgia) associated with inflammation after the procedure. It is also essential to monitor the child's symptoms and seek medical attention if the pain worsens or is accompanied by other symptoms like fever, which can indicate an infection.
