It is estimated that lead-poisoned children are identified by screening procedures rather than through clinical recognition of lead-related symptoms in

Correct Answer: A

Rationale: The correct answer is A) 99% of cases. Lead poisoning in children is often asymptomatic or presents with vague symptoms that can easily be overlooked. Screening procedures, such as blood lead level testing, are crucial in identifying children with lead poisoning early on, even before they develop clinical symptoms. This early detection allows for timely intervention to prevent further exposure and minimize health consequences. Option B) 79% of cases is incorrect because lead poisoning can occur without obvious clinical symptoms, making reliance on clinical recognition alone inadequate. Option C) 59% of cases is incorrect as it underestimates the importance of screening procedures in identifying lead-poisoned children who may not exhibit noticeable symptoms. Option D) 39% of cases is incorrect as it also downplays the significance of systematic screening in detecting lead poisoning cases, especially in asymptomatic children. In an educational context, it is crucial for healthcare providers, especially pediatric nurses, to understand the importance of routine lead screening in at-risk populations to ensure early identification and intervention. Emphasizing the reliance on screening procedures over clinical recognition can help prevent the long-term consequences of lead exposure in children.

Correct Answer: C

Rationale: Allergic shiners represent dark circles under the eyes, making option C the correct answer. This physical characteristic is often seen in children with allergies due to the pooling of blood under the eyes resulting from nasal congestion and inflammation. The dark circles are a common sign of allergies in pediatric patients. Option A, an upward rubbing of the nose with an open palm, is incorrect as it describes a behavior that may occur due to nasal congestion but is not directly related to allergic shiners. Option B, continuous open-mouth breathing, is also incorrect as it is more indicative of respiratory distress rather than allergic shiners. Option D, a transverse crease of the nose, is associated with allergic salute, which involves upwardly rubbing the nose with the palm but is not specific to allergic shiners. Understanding these physical signs and symptoms is crucial for pediatric nurses to accurately assess and manage pediatric patients with allergies. Recognizing allergic shiners can aid in early identification and appropriate interventions to help alleviate symptoms and improve the child's quality of life.

Correct Answer: C

Rationale: The correct answer is C) 6 yr. In pediatric nursing, understanding the age of onset for asthma is crucial for early detection and management. Asthma commonly presents in childhood, with around 80% of cases manifesting before the age of 6 years. This early onset is significant because it allows healthcare providers to intervene promptly, provide appropriate treatment, and educate both the child and their caregivers on managing the condition effectively. Option A) 2 yr is incorrect because while asthma can develop at this age, the majority of cases occur later, around 6 years old. Option B) 4 yr is also incorrect as it is still slightly early for the typical onset of asthma. Option D) 8 yr is incorrect because by this age, most asthmatic patients have already experienced symptoms and received a diagnosis. Educationally, understanding the age of onset for asthma helps nurses and healthcare providers in pediatric settings to recognize symptoms early, differentiate asthma from other respiratory conditions, and tailor treatment plans to suit the child's age and developmental stage. It also emphasizes the importance of proactive asthma management to improve quality of life and prevent exacerbations in pediatric patients.

Correct Answer: D

Rationale: In the management of step-6 severe persistent asthma in a 6-year-old boy, the best treatment option is D) high-dose inhaled corticosteroids with long-acting B-agonist and oral corticosteroids along with omalizumab therapy. This comprehensive approach is necessary to address the severity of the condition and achieve optimal control. High-dose inhaled corticosteroids with long-acting B-agonists help to reduce inflammation and provide bronchodilation. Oral corticosteroids may be required during exacerbations to control symptoms and prevent further complications. Omalizumab, a monoclonal antibody, is recommended for children with severe allergic asthma to target specific immune responses. The other options are suboptimal for step-6 severe persistent asthma. Option A lacks the addition of oral corticosteroids and omalizumab, which are crucial for severe cases. Option B includes a leukotriene receptor antagonist instead of omalizumab, which may not be as effective in severe asthma. Option C suggests low-dose inhaled corticosteroids, which are insufficient for managing severe persistent asthma in this age group. Educationally, understanding the stepwise approach to asthma management in children is vital for healthcare providers caring for pediatric patients. It highlights the importance of individualized treatment plans based on disease severity and the need for a multidisciplinary approach in managing complex cases like severe persistent asthma.

Correct Answer: A

Rationale: Atopic dermatitis, also known as eczema, typically begins in infancy. This is the correct answer because atopic dermatitis is a common skin condition that often appears in early childhood, with an onset usually before the age of 5. Infancy is a critical period for the development of atopic dermatitis due to the immaturity of the skin barrier and immune system in babies. Option B, toddlerhood, is incorrect because atopic dermatitis commonly starts before the toddler years. While it can continue into toddlerhood, the onset is typically earlier. Option C, preschooler age, is also incorrect as atopic dermatitis usually manifests before the child reaches preschool age. By preschool age, the condition may have already been present for a few years. Option D, school age, is incorrect because atopic dermatitis tends to begin earlier, usually in infancy or early childhood. By the time a child reaches school age, the condition would have likely already been diagnosed and managed. Understanding the typical onset age of atopic dermatitis is important for healthcare providers, especially pediatric nurses, as they care for young children who may be affected by this condition. Early recognition and appropriate management are crucial in providing relief to the child and support to their families. By knowing when atopic dermatitis typically begins, nurses can better educate parents on prevention strategies, symptom management, and treatment options.
