A parent calls the pediatric clinic asking for advice on treating lice. The child has already been treated once with lindane(Qwell). Which advice from the nurse is the most appropriate?

Correct Answer: C

Rationale: The correct answer is C because malathion(Ovide) is a recommended alternative treatment for lice when lindane(Qwell) has already been used. Malathion works differently and may be more effective in this case. Choice A is incorrect as lice do not typically survive off the human scalp for long. Choice B is incorrect because using the same treatment multiple times may not be effective. Choice D is incorrect as oral medications are not typically recommended for lice treatment.

Correct Answer: C

Rationale: The correct answer is C: Request a patient-controlled analgesia (PCA) pump for the client. This option is appropriate because the client is experiencing severe pain (level 10) due to full-thickness burns, which require consistent pain management. PCA allows the client to self-administer pain medication within safe limits, ensuring adequate pain control. It provides better pain relief compared to intermittent dosing like IM injections every 2 hours. Option A is incorrect because administering 5 mg of morphine immediately may not provide sustained pain relief and could lead to overmedication. Option B is not the best choice as it delays immediate pain relief and does not address the need for continuous pain management. Option D is also not ideal as assessing for complications should not delay pain relief and is not as effective as providing continuous pain control with a PCA pump.

Correct Answer: B

Rationale: The correct answer is B because the foul odor is expected when using enzymatic debriding agents, indicating the breakdown of necrotic tissue. The nurse should explain this to the client to alleviate concerns. Choice A is not necessary as the nurse can handle the situation independently. Choice C is irrelevant to addressing the foul odor. Choice D is not indicated as antibiotics are not typically used for managing a foul odor related to enzymatic debridement.

Correct Answer: A

Rationale: The correct answer is A: Infection. Sebaceous cysts can become infected due to bacteria entering the cyst, causing inflammation, redness, and pain. Infection can lead to abscess formation and require medical intervention. Keratin horn formation (B) is a rare occurrence associated with epidermoid cysts, not sebaceous cysts. Calcification (C) is not a common complication of sebaceous cysts. Ulceration (D) may occur if the cyst is traumatized but is not a typical complication.

Correct Answer: C

Rationale: The correct answer is C. Cystic hygromas are lymphatic malformations that are typically located in the neck and are filled with lymphatic fluid. They are supremely transilluminable due to their fluid content, which allows light to pass through easily. This characteristic helps differentiate them from other neck masses. Explanation for other choices: A: They do not arise from the carotid body lymph sac in the neck. Cystic hygromas are not associated with the carotid body. B: They can be unilocular or multilocular, so stating they consist of a unilocular cystic mass is not entirely accurate. D: It is not inherently dangerous to treat cystic hygromas with alcohol sclerotherapy, but careful consideration and expertise are necessary to avoid complications.
