Correct Answer: B

Rationale: The correct statement regarding 2-rescuer child CPR is to compress the chest with one or two hands to a depth equal to one-half to one third the diameter of the chest. This technique ensures effective chest compressions without causing excessive damage to the chest. Choice A is incorrect because allowing the chest to fully recoil between compressions is essential to facilitate optimal blood flow during CPR. Choice C is incorrect as it describes a compression to ventilation ratio of 30:2, which is not the recommended ratio for child CPR. Choice D is incorrect as a compression to ventilation ratio of 15:2 is not standard practice for child CPR, and pauses in compressions are necessary to provide ventilations effectively.

Correct Answer: B

Rationale: The correct way to prevent tinea pedis is by keeping the feet dry, especially between the toes, to decrease the risk of fungal infection. Choice A is incorrect as keeping the feet moist can promote fungal growth. Choice C is incorrect because nylon or synthetic socks can trap moisture, contributing to the growth of fungi. Choice D is incorrect as going barefoot in public, especially in areas like locker rooms, increases the risk of contracting tinea pedis.

Correct Answer: B

Rationale: The correct first action before administering tube feeding to an infant is to offer a pacifier. Providing a pacifier stimulates the sucking reflex, aiding in digestion and providing comfort to the infant. Irrigating the tube with water (Choice A) is not typically the initial step and could potentially introduce unnecessary fluid into the infant's system. Slowly instilling formula (Choice C) should only be done after ensuring the tube is appropriately placed. Placing the infant in the Trendelenburg position (Choice D) is not necessary for tube feeding and could pose risks such as aspiration.

Correct Answer: C

Rationale: The correct answer is to maintain standard and contact precautions. RSV is highly contagious, primarily spreading through respiratory secretions. Therefore, it is crucial to implement infection control measures to prevent the spread of the virus within the healthcare setting. Option A is incorrect as warmth and dryness are not the primary concern in RSV management. While family support is important, allowing visits may increase the risk of spreading the infection, making option B less appropriate. Option D is incorrect because RSV is a viral infection, and antibiotics are not effective against viruses.

Correct Answer: B

Rationale: Antifungal agents are the appropriate treatment for candidal diaper rash as it is a fungal infection. Corticosteroids, antibiotics, and retinoids are not indicated for this condition. Corticosteroids may worsen fungal infections, antibiotics are used for bacterial infections, and retinoids are typically used for acne and skin conditions unrelated to candidal diaper rash.
