Correct Answer: A

Rationale: The correct initial action for the school nurse is to assess for signs and symptoms of anaphylaxis (Choice A). This is crucial as anaphylaxis is a severe allergic reaction that can be life-threatening and requires immediate intervention. Assessing for anaphylaxis symptoms such as difficulty breathing, swelling of the face or throat, and a rapid pulse helps the nurse quickly identify the severity of the situation. Administering OTC antihistamines (Choice C) or epinephrine (Choice D) should only be done after confirming the presence of anaphylaxis. Assessing for erythema and urticaria (Choice B) is important but not as immediate as assessing for signs of anaphylaxis in this scenario.

Correct Answer: D

Rationale: The correct answer is D because it emphasizes the importance of consistent and correct condom use in preventing HIV transmission. Here's the rationale: 1. Abstinence is the most effective way to prevent HIV, but since the teen is sexually active, abstinence may not be feasible for her. 2. Using condoms consistently and correctly is the next best method for preventing HIV transmission during sexual activity. 3. Choice A is incorrect because it implies that using condoms is not effective, which is not true. 4. Choice B is incorrect because it only mentions female condoms, while both male and female condoms can be effective in preventing HIV. 5. Choice C is incorrect because while new prevention methods are being researched, the established method of consistent condom use remains the most effective.

Correct Answer: D

Rationale: The correct answer is D: Acyclovir (Zovirax). Acyclovir is an antiviral medication specifically used to treat herpes infections, including genital herpes. It works by inhibiting the replication of the herpes virus, thereby suppressing symptoms and shortening the course of the infection. Clotrimazole (A) is an antifungal medication used to treat yeast infections, not effective against viral infections like herpes. Metronidazole (B) is an antibiotic used to treat bacterial infections, not effective against viruses. Podophyllin (C) is a topical treatment for genital warts caused by the human papillomavirus (HPV), not effective for herpes. Therefore, the correct choice is Acyclovir (D) for treating genital herpes exacerbation.

Correct Answer: D

Rationale: The correct answer is D because cleansing the meatus with circular strokes starting at the meatus and moving outward helps prevent the introduction of bacteria into the urethra. This technique minimizes the risk of urinary tract infections. Holding the shaft at a 60-degree angle (A) or with the dominant hand (B) is not necessary for catheter insertion. Cleansing the meatus 3 times with the same cotton ball (C) can introduce more bacteria and is not recommended.

Correct Answer: D

Rationale: The correct answer is D: She must make arrangements to stay somewhere other than her home until the children are no longer contagious. 1. The patient's newborn is at risk of contracting chickenpox from the infected children. 2. Chickenpox can be severe in newborns due to their immature immune systems. 3. It is crucial to protect the newborn by ensuring they are not exposed to the virus. 4. Staying elsewhere until the children are no longer contagious will prevent transmission to the newborn. Incorrect choices: A: Acyclovir is not recommended for prophylactic treatment in this situation. B: Immunity is not automatically transferred from the mother to the baby for chickenpox. C: Allowing the infected children to visit with precautions is not sufficient to protect the newborn.
