Which of the ff. would the nurse explain to a patient is the main purpose of a hearing aid?

Correct Answer: D

Rationale: The main purpose of a hearing aid is to improve the patient's ability to hear. Hearing aids are devices designed to amplify sound for individuals with hearing loss or difficulty hearing. They do not amplify background noise or musical sounds specifically; instead, they are meant to enhance the overall perception of sounds to help individuals better understand speech and communicate effectively. Moreover, hearing aids do not occlude the ear, but rather are used to transmit sound into the ear canal to make sounds louder and clearer for the wearer.

Correct Answer: B

Rationale: Providing a solution of hydrogen peroxide and water for use as a mouth rinse is most likely to decrease the pain of stomatitis. Stomatitis is inflammation of the oral mucous membranes and can be quite painful for oncology clients undergoing chemotherapy. Using a solution of hydrogen peroxide and water as a mouth rinse can help reduce the risk of infection and promote healing of the mucous membranes, thereby decreasing the pain associated with stomatitis. This intervention helps to maintain oral hygiene and prevent further complications, making it an effective way to manage the client's symptoms while undergoing chemotherapy. It is important to note that discontinuing chemotherapy would not be a recommended intervention as it is the primary treatment for the client's cancer. Monitoring platelet and leukocyte counts and checking for signs and symptoms of stomatitis are important aspects of care, but providing a mouth rinse would directly address the pain and discomfort experienced by the client.

Correct Answer: D

Correct Answer: B

Rationale: Uremic frost is a term used to describe the presence of urea crystals on the skin of individuals with chronic renal failure. As kidney function declines in chronic renal failure, the body is unable to effectively excrete waste products such as urea. Urea can then be deposited on the skin when sweating, leading to the formation of white or frost-like crystals, giving the appearance of "uremic frost." This condition is a visible indicator of severe kidney dysfunction and the buildup of waste products in the body.
