Correct Answer: D

Rationale: The correct answer is D, severe joint pain. Rheumatic fever commonly presents with severe joint pain due to joint inflammation. Jaundice (choice A) is not typically associated with rheumatic fever. Peeling skin on the hands and feet (choice B) is more indicative of conditions like Kawasaki disease. While a high fever (choice C) can be present, it is not as specific to rheumatic fever as severe joint pain. Severe joint pain, along with other criteria like carditis, subcutaneous nodules, erythema marginatum, and Sydenham chorea, are major criteria used in the diagnosis of rheumatic fever.

Correct Answer: A

Rationale: The priority nursing intervention for a child with leukemia receiving chemotherapy is monitoring for signs of infection. Chemotherapy can suppress the immune system, putting the child at a higher risk of developing infections. Early detection of signs of infection is crucial to prevent serious complications and initiate timely treatment. Providing nutritional support is important for overall health but is not the priority when the child is at risk of infection. Monitoring for signs of bleeding is essential, but infection surveillance takes precedence due to the immediate threat it poses to the child's health. Monitoring for signs of pain is important for comfort but is not the priority over infection prevention and management.

Correct Answer: B

Rationale: The correct answer is B: "Put on gloves because standard precautions are required." Standard precautions are essential in healthcare settings to prevent the transmission of infections, and wearing gloves is a crucial part of these precautions during immunizations. Choice A is incorrect because speaking with the nurse manager about techniques does not address the immediate need for wearing gloves. Choice C is incorrect because gloves are indeed needed to prevent the spread of infections. Choice D is incorrect as evaluating the child's appearance is not a substitute for wearing gloves which are a basic infection control measure.

Correct Answer: B

Rationale: The priority nursing intervention for a child hospitalized for acute lymphoblastic leukemia (ALL) is preventing infection. Children with ALL have compromised immune systems, making them highly vulnerable to infections. Preventing infections through strict aseptic techniques, isolation precautions, and proper hygiene is crucial to safeguard the child's health. Administering antibiotics (choice A) may be necessary if an infection occurs, but the primary focus should be on infection prevention. While providing nutritional support (choice C) is important, preventing infection takes precedence due to its direct impact on the child's survival. Managing pain (choice D) is essential for the child's comfort but is not the priority over preventing life-threatening infections in this scenario.

Correct Answer: B

Rationale: The correct answer is B. Setting the water heater at 130 degrees is incorrect because water heaters should be set to no higher than 120 degrees to prevent scald burns. Choice A is correct as leaving fireworks displays to professionals reduces the risk of burns. Choice C is also correct as flame-retardant sleepwear reduces the risk of burn injuries. Choice D is correct as keeping pot handles facing inward prevents accidental spills and burns.
