Correct Answer: D

Rationale: During the school-age years, children are more physically active and curious, which increases their risk of accidents and injuries. This developmental stage is characterized by increased exploration and engagement in physical activities. While infections and poisonings are important health concerns, school-age children are more likely to be affected by accidents and injuries due to their active nature. Risk-taking behaviors may become more prevalent in adolescence rather than during the school-age period, making it a less likely focus for the nurse during the health assessment of a school-age child.

Correct Answer: C

Rationale: The correct preoperative intervention for a child with pyloric stenosis is to monitor for signs of dehydration. Pyloric stenosis involves the obstruction of the pyloric sphincter, leading to projectile vomiting, which can result in dehydration and electrolyte imbalances. Monitoring for signs of dehydration is crucial to assess the child's fluid status and prevent complications. Administering intravenous fluids, although important in managing dehydration, is not typically a preoperative intervention but rather a treatment during or after surgery. Monitoring for signs of infection and pain may also be important but are not the priority preoperative interventions in a child with pyloric stenosis.

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: Colicky behavior in infants is primarily characterized by paroxysmal abdominal pain, resulting in excessive crying and fussiness. The pain episodes are often unpredictable and can be distressing for both the infant and the parents. Inadequate peristalsis (Choice A) refers to weak or ineffective bowel movements and is not the typical cause of colic. While some infants may experience colic due to an allergic response to certain proteins in milk (Choice C), this is not the primary cause of colic behavior in all infants. Choice D, a protective mechanism designed to eliminate foreign proteins, is not a recognized cause of colic. Therefore, the correct explanation for the cause of colicky behavior in infants is paroxysmal abdominal pain.

Correct Answer: D

Rationale: Initiating pain assessment with a standardized pain scale is crucial in effectively managing pain during a sickle cell crisis. This initial step helps the nurse understand the severity of the pain, which guides subsequent interventions. Administering medications, such as NSAIDs or meperidine, should only be done after a thorough pain assessment to ensure appropriate and individualized treatment. Using guided imagery and therapeutic touch may be beneficial as adjunct interventions, but they should not replace the essential first step of assessing the pain level accurately.
