A child has been diagnosed with scabies and the parents are taught about the use of 5% permethrin lotion(Elimite). Which statement by the parents indicates the need for further instruction?

Correct Answer: B

Rationale: The correct answer is B. Leaving the lotion on until the next day and giving a bath is incorrect as per the treatment guidelines for scabies. The rationale is that permethrin lotion should be applied on dry skin and left on for 8-14 hours before washing off. This allows the medication to work effectively. Giving a bath right after applying the lotion can wash off the medication prematurely, reducing its efficacy. A: This statement is correct as it describes the correct application of Elimite from the nape of the neck to the toes, except on the genitals. C: This statement is correct as scabies treatment often requires a second application one week after the first to ensure all mites are eradicated. D: This statement is correct as it is recommended to give a warm soapy bath before applying the lotion to clean the skin.

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: The correct answer is B because a dose pack of prednisone is designed to provide a tapering dose regimen. Prednisone should not be abruptly stopped to prevent adrenal insufficiency. Tapering the dose gradually allows the body to adjust and minimize withdrawal symptoms. Choice A is incorrect because prednisone helps reduce inflammation, not decrease it. Choice C is incorrect as the dose pack typically starts with a higher dose then tapers down. Choice D is incorrect because while prednisone may reduce redness, the main purpose of the dose pack is to taper the medication.

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.
