A nurse is teaching a class about physiological changes to hearing in older adult clients. Which of the following should the nurse include?

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 with an upper respiratory infection. Antifungal cream is a topical medication that kills or inhibits fungi that cause skin infections. Upper respiratory infection is not a skin infection, but an infection of the nose, throat, or sinuses. Antifungal cream has no effect on upper respiratory infection and may cause adverse effects or resistance.

Choice A Reason: "I ate shellfish about 2 weeks ago at a local restaurant." supports the medical diagnosis of hepatitis A, which is an infection of the liver caused by the hepatitis A virus (HAV). HAV is transmitted by fecal-oral route, meaning that it can be contracted by ingesting contaminated food or water, such as raw or undercooked shellfish from polluted waters. The incubation period for hepatitis A is about two to six weeks.

Choice B Reason: "I was an intravenous drug abuser in the past and shared needles." does not support the medical diagnosis of hepatitis A, but may indicate exposure to hepatitis B or C, which are infections of the liver caused by the hepatitis B virus (HBV) or hepatitis C virus (HCV). HBV and HCV are transmitted by blood or body fluids, meaning that they can be contracted by sharing needles, syringes, or other injection equipment with infected people.

Choice C Reason: "I had a blood transfusion in 1980 after major abdominal surgery." does not support the medical diagnosis of hepatitis A, but may indicate exposure to hepatitis B or C, which are infections of the liver caused by the hepatitis B virus (HBV) or hepatitis C virus (HCV). HBV and HCV are transmitted by blood or body fluids, meaning that they can be contracted by receiving blood transfusions or organ transplants from infected donors. However, since 1992, all donated blood in the United States has been screened for HBV and HCV.

Choice D Reason: "I have had unprotected sex with multiple partners." does not support the medical diagnosis of hepatitis A, but may indicate exposure to hepatitis B or C, which are infections of the liver caused by the hepatitis B virus (HBV) or hepatitis C virus (HCV). HBV and HCV are transmitted by blood or body fluids, meaning that they can be contracted by having unprotected sex with infected people. However, sexual transmission of HAV is rare, unless there is contact with fecal matter.
