Correct Answer: C

Rationale: During a tonic-clonic seizure, the priority nursing responsibility is to protect the child from self-injury. Applying restraints is not recommended during a seizure as it can lead to further harm. Administering oxygen may be necessary after the seizure to support oxygenation, but it is not the priority during the seizure itself. Inserting a plastic airway is also not indicated as the jaw is clamped, and the child should not have anything placed in the mouth during a seizure. Therefore, the correct action is to ensure the child's safety by protecting them from self-injury, preventing harm from uncontrolled movements and potential falls.

Correct Answer: B

Rationale: The correct answer is B. Tap water enemas can cause significant fluid and electrolyte imbalances, particularly in infants, making them unsafe for this age group. Choice A is incorrect because tap water enemas do not directly lead to loss of necessary nutrients. Choice C is incorrect as it focuses on emotional impact rather than physiological risks. Choice D is incorrect as shock from a sudden drop in temperature is not a common consequence of a tap water enema in this scenario.

Correct Answer: A

Rationale: Rubeola (measles) is characterized by a high fever and the presence of Koplik spots, which are not seen in rubella (German measles). Therefore, the correct answer is A. Choice B, rash on the trunk with pruritus, is more indicative of rubella rather than rubeola. Choice C, nausea, vomiting, and abdominal cramps, are not specific differentiating symptoms between rubeola and rubella. Choice D, characteristics of a cold followed by a rash, does not specifically distinguish between rubeola and rubella.

Correct Answer: B

Rationale: The correct preoperative teaching for a 2-year-old child undergoing surgery involves using a doll to demonstrate the procedure. This method helps the child understand what to expect in a non-threatening and visual way, making the experience less intimidating. Explaining the procedure in simple terms (Choice A) may not effectively convey the details to a young child. Showing pictures of the hospital environment (Choice C) may not directly address the surgical procedure itself. Allowing the child to play with medical equipment (Choice D) can be unsafe and may not effectively prepare the child for the surgery.

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.
