A client arrives to the clinic with reports of progressive weakness in his lower extremities. Which of the following findings in the client's history is consistent with the client developing Guillain-Barre syndrome?

Choice A reason: This is incorrect because education about mastoidectomy is not relevant for a client with an upper respiratory infection. Mastoidectomy is a surgical procedure that removes part or all of the mastoid bone behind the ear, which can become infected or inflamed due to chronic or recurrent middle ear infections. The nurse should assess the client's ear for signs of mastoiditis, such as swelling, tenderness, or redness behind the ear, but mastoidectomy is not a common or first-line treatment for upper respiratory infection.
Choice B reason: This is incorrect because a referral for a hearing test is not necessary for a client with an upper respiratory infection. Hearing test is a diagnostic tool that measures how well a person can hear different sounds at different frequencies and intensities. The nurse should ask the client about any changes in hearing or tinnitus, which are possible complications of upper respiratory infection, but a hearing test is not a routine or urgent intervention for this condition.
Choice C reason: This is correct because education on the administration of oral antibiotics can help treat an upper respiratory infection. Antibiotics are drugs that kill or inhibit bacteria that cause infections. Upper respiratory infections can be caused by various pathogens, such as viruses, bacteria, or fungi, but bacterial infections are more likely to cause fever, otalgia, or purulent nasal drainage. The nurse should instruct the client on how to take antibiotics as prescribed, such as dosage, frequency, duration, side effects, and interactions.
Choice D reason: This is incorrect because a prescription for an antifungal cream is not appropriate for a client

Choice A Reason: Inserting a nasal swab to observe the fluid is contraindicated, as it can introduce infection or increase intracranial pressure. The fluid can be tested for glucose or halo sign to confirm cerebrospinal fluid (CSF) leakage.

Choice B Reason: Suctioning the nose gently with a bulb syringe is also contraindicated, as it can create negative pressure and increase CSF leakage or cause meningitis.

Choice C Reason: This is the correct answer because allowing the drainage to drip onto a sterile gauze pad can prevent contamination and facilitate observation of the amount and characteristics of the fluid.

Choice D Reason: Inserting sterile packing into the nares is not recommended, as it can obstruct the drainage and increase intracranial pressure or infection risk.
