Correct Answer: B

Rationale: The correct answer is B: Long-lasting active immunity is conferred. Tetanus toxoid injection works by stimulating the child's body to produce its antibodies, providing long-lasting active immunity. Choice A is incorrect because passive immunity is not conferred for life; it is temporary and involves receiving antibodies rather than producing them internally. Choice C is incorrect as the immunity conferred by the tetanus toxoid injection is not lifelong natural immunity but rather active immunity stimulated by the body's immune response. Choice D is also incorrect since passive natural immunity is not conferred by the tetanus toxoid injection, and it is not temporary.

Correct Answer: B

Rationale: The most important nursing intervention for a child with bronchiolitis is providing respiratory therapy. This intervention helps to maintain airway patency and improve breathing by assisting with mucus clearance and ventilation. Administering bronchodilators (Choice A) may be considered in some cases, but it is not the most crucial intervention for bronchiolitis. Monitoring oxygen saturation (Choice C) is important but is not as directly impactful as providing respiratory therapy. Encouraging fluid intake (Choice D) is important for hydration but does not directly address the respiratory distress associated with bronchiolitis.

Correct Answer: A

Rationale: The correct first intervention when managing a child with diabetic ketoacidosis is to begin intravenous saline solution to address dehydration and restore electrolyte balance. Rehydration is essential to improve perfusion and correct electrolyte imbalances. Administering insulin without addressing dehydration can potentially lead to further complications. Placing the child on a cardiac monitor or pulse oximetry monitor is important but not the initial priority in managing DKA.

Correct Answer: A

Rationale: The correct answer is to monitor for signs of infection. When a child is undergoing chemotherapy, their immune system is compromised, making them more susceptible to infections. Monitoring for signs of infection is crucial to promptly identify and treat any potential infections. Choices B, C, and D are incorrect because although monitoring for bleeding, dehydration, and pain are important aspects of care, the priority for a child receiving chemotherapy is to prevent and detect infections due to their increased vulnerability.

Correct Answer: B

Rationale: When an adolescent with type 1 diabetes experiences an insulin reaction, it is essential to quickly raise their blood sugar levels. Buying a soda and a hamburger to eat is the best choice in this situation as it provides a fast-acting source of sugar to counteract hypoglycemia. Calling parents immediately may cause a delay in receiving appropriate treatment. Administering insulin would further lower blood sugar levels, worsening the situation. Leaving the arena and resting would not address the immediate need to raise blood sugar levels.
