Which of the following situations increase the risk of lead poisoning in children?

Correct Answer: B

Rationale: Playing in sand at the park can increase the risk of lead poisoning in children because sand can be contaminated with lead particles from various sources such as old paint, industrial pollution, or leaded gasoline residues. When children play in sand, they may accidentally ingest the contaminated particles while handling or playing with the sand. This ingestion can lead to lead poisoning, as even small amounts of lead can be harmful to children's health. Therefore, playing in sand at the park poses a higher risk of lead exposure compared to the other activities listed.

Correct Answer: B

Rationale: Type 2 diabetes mellitus (DM) most likely results from heterogeneous risk factors, such as obesity, unhealthy diet, sedentary lifestyle, genetic predisposition, and other lifestyle factors. By addressing these risk factors through lifestyle modifications, such as maintaining a healthy diet and regular exercise, the development of Type 2 DM can often be prevented or delayed. On the other hand, Type 1 diabetes is primarily an autoimmune condition where the body mistakenly attacks insulin-producing cells in the pancreas, and it is not preventable. Gestational diabetes occurs during pregnancy and is influenced by hormonal changes during pregnancy and other factors, making it less preventable through lifestyle changes alone. Thus, Type 2 diabetes is the type that is most preventable through lifestyle modifications.

Correct Answer: C

Rationale: Idiopathic thrombocytopenic purpura (ITP) is a condition characterized by a low platelet count, which can lead to an increased risk of bleeding. Steroids are often prescribed to help increase platelet production in patients with ITP. Therefore, the nurse should monitor the child for signs of bleeding, such as petechiae, ecchymosis, gum bleeding, and other unusual bleeding manifestations. Monitoring for bleeding is crucial to assess the effectiveness of the steroid treatment and to prevent complications associated with ITP.

Correct Answer: C

Rationale: The most appropriate intervention to decrease cardiac demands and minimize cardiac workload in children with heart disease is to schedule care to provide uninterrupted rest periods. By allowing the child to rest without interruptions, their heart will not have to work as hard, promoting better overall cardiac function. This intervention focuses on promoting rest and recovery, which is crucial for children with heart disease to maintain optimal cardiac health. Feeding the infant over long periods may not necessarily decrease cardiac demands, and allowing the infant to have her way to avoid conflict is not related to cardiac workload. Developing and implementing a consistent care plan is important but may not directly decrease cardiac demands as effectively as scheduling care for uninterrupted rest periods.

Correct Answer: A

Rationale: The presence of a chronic cough, along with diffuse wheezing during the expiratory phase of respiration, suggests asthma. Asthma is a chronic condition characterized by inflammation and narrowing of the airways, causing symptoms such as coughing, wheezing, and difficulty breathing. The wheezing sound typically occurs during expiration due to air trapping in the narrowed airways. In this case, the absence of retractions (which could indicate increased work of breathing) and the nature of the wheezing pattern are more consistent with asthma rather than other conditions such as pneumonia, croup, or foreign body aspiration. While these other conditions may also present with respiratory symptoms, the specific combination of chronic cough and expiratory wheezing is most indicative of asthma in this scenario.
