The client is prescribed silver sulfadiazine for a partial-thickness burn to the back. Which information should the nurse discuss concerning this medication?

Correct Answer: A

Rationale: The correct answer is A. Silver sulfadiazine can cause kidney damage due to its effect on renal function. Encouraging the client to drink 3,000 mL of water helps prevent kidney damage by promoting adequate hydration and maintaining kidney function. B: While protein is important for wound healing, it is not directly related to the medication. C: Testing urine for ketones is not necessary unless the client is at risk for diabetic ketoacidosis, which is not related to silver sulfadiazine. D: Changing the dressing twice a day is important for wound care but not specifically related to the medication's side effects.

Correct Answer: B

Rationale: Rationale: 1. Papillomas are benign growths of epithelial origin, making option B correct. 2. Option A is incorrect as papillomas are actually common non-cancerous growths. 3. Option C is incorrect as papillomas are typically not pigmented with melanin. 4. Option D is incorrect as papillomas are not specifically keratinized or limited to columnar epithelium.

Correct Answer: D

Rationale: The correct answer is D: CN VIII. This cranial nerve, known as the vestibulocochlear nerve, is commonly affected by tumors due to its location near the cerebellopontine angle. Tumors in this area can compress CN VIII, leading to symptoms such as hearing loss, vertigo, and imbalance. CN II (A), CN IV (B), and CN V (C) are less commonly affected by tumors compared to CN VIII. CN II is the optic nerve, CN IV is the trochlear nerve, and CN V is the trigeminal nerve, each with different functions and locations in the brain. Therefore, D is the most likely cranial nerve to be affected by a tumor based on its anatomical proximity to common tumor sites.

Correct Answer: A

Rationale: The correct answer is A because melanoma is typically fast-growing, asymmetrical, and raised. Melanomas often exhibit irregular borders, different colors within the lesion, and a larger size. This is due to the rapid proliferation of melanocytes, the pigment-producing cells, which leads to the characteristic appearance of melanoma. Choices B, C, and D are incorrect because melanomas are not typically slow-growing, symmetrical, flat, or bleeding. Slow growth is more common in benign lesions, while symmetry, flatness, and bleeding are not typical features of melanoma. Therefore, option A best represents the common characteristics of melanoma based on its growth patterns and appearance.

Correct Answer: B

Rationale: The correct answer is B: Standard precautions. Standard precautions should be implemented when changing a dressing on a client's abdomen as it includes hand hygiene, gloves, and appropriate personal protective equipment based on the risk of exposure to blood or body fluids. This technique helps prevent the spread of infection and ensures the safety of both the nurse and the client. A: Contact precautions are used for clients with specific infections that can be transmitted by direct contact. C: Droplet precautions are for infections transmitted through respiratory droplets. D: Airborne precautions are for infections transmitted via small particles that remain in the air for a long time. In summary, Standard precautions are the most appropriate technique for changing a dressing on a client's abdomen as they provide a comprehensive approach to infection prevention.
