The client inquires what the positive result from the potassium hydroxide (KOH) test indicates. Which of the following is an accurate response by the nurse?

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: This is incorrect because this comment does not require reporting to the client's provider. It is normal to have reduced vision and an increased risk of falling with a patch on one eye after cataract surgery. The nurse should reassure the client, provide assistance with mobility, and educate the client on safety measures.

Choice B reason: This is incorrect because this comment does not require reporting to the client's provider. It is normal to have some itching and discomfort in the eye after cataract surgery. The nurse should commend the client for not rubbing the eye, as this can cause infection or damage to the surgical site. The nurse should also administer anti-inflammatory eye drops as prescribed and instruct the client on how to apply them.

Choice C reason: This is incorrect because this comment does not require reporting to the client's provider. It is normal to have increased sensitivity to light in the eye after cataract surgery. The nurse should dim the lights in the room, provide sunglasses or a shield for the eye, and educate the client on how to protect the eye from bright light.

Choice D reason: This is the correct answer because this comment requires reporting to the client's provider. Severe pain in the eye after cataract surgery can indicate a complication such as infection, inflammation, bleeding, or increased intraocular pressure. The nurse should assess the eye for signs of redness, swelling, discharge, or bleeding, and report the findings and the pain level to the provider. The nurse should also administer analgesics as prescribed and monitor the pain relief.
