What important safety measure regarding the use of insect repellents does the nurse teach a parenting group?

Correct Answer: A

Rationale: Step-by-step rationale: 1. Applying repellents to clothing reduces skin exposure. 2. It minimizes direct contact with skin, preventing potential irritation. 3. It also decreases absorption risks. 4. This method is safer, especially for children with sensitive skin. Summary of incorrect choices: B: DEET is not the only effective repellent; there are safe alternatives. C: Oil of lemon eucalyptus is not recommended for babies due to potential skin sensitivity. D: Washing off after 2 hours may reduce efficacy; reapplication is necessary for continued protection.

Correct Answer: B

Rationale: The correct answer is B: Avoid cutting the dressing when applying it to the wound. Actisorb Silver 222 dressing should not be cut as it may disrupt its antimicrobial properties, affecting its effectiveness in managing the wound. Cutting the dressing could also lead to uneven coverage of the wound, potentially causing complications. Performing sterile dressing changes twice a day (choice A) may not be necessary unless specified by the healthcare provider. Premedicating the client with a narcotic analgesic (choice C) is not directly related to the dressing application and should be determined based on the client's pain level. Using tape to hold the secondary dressing in place (choice D) is not recommended as it may cause skin irritation or damage.

Correct Answer: C

Rationale: The correct answer is C because lindane shampoo should be applied to dry hair and then lathered with a small amount of water. This allows for better penetration of the medication into the hair and scalp to effectively treat pediculosis capitis. Washing the hair with an antimicrobial shampoo prior to lindane (choice A) is unnecessary and may reduce the efficacy of lindane. Scrubbing the head for 2 minutes before removing lindane (choice B) can also lead to inadequate treatment. Using lindane shampoo daily for a week (choice D) is incorrect as lindane should not be used daily due to its potential toxicity.

Correct Answer: C

Rationale: The correct answer is C because seborrhoeic keratosis often appears greasy due to the overproduction of sebum. This is a characteristic feature of this benign skin lesion. Choice A is incorrect as seborrhoeic keratosis typically occurs in older individuals, not teenagers. Choice B is incorrect as seborrhoeic keratosis is usually raised and has a waxy, stuck-on appearance, rather than flat. Choice D is incorrect as seborrhoeic keratosis is not a squamous cell papilloma, but rather a benign growth of keratinocytes.

Correct Answer: B

Rationale: The correct answer is B because there are indeed three types of neurofibromatosis: NF1, NF2, and schwannomatosis. NF1 and schwannomatosis have autosomal dominant inheritance, while NF2 has autosomal dominant inheritance with variable penetrance. Choice A is incorrect because types of neurofibromatosis do not have autosomal recessive inheritance. Choice C is incorrect because von Recklinghausen's disease is synonymous with neurofibromatosis type 1, not type 2. Choice D is incorrect because cutaneous lesions in neurofibromatosis are typically not painful.
