Children exposed to second-hand tobacco smoke have increased frequency of

Correct Answer: A

Rationale: In pediatric nursing, understanding the impact of second-hand tobacco smoke exposure on children's health is crucial. The correct answer is A) middle ear effusions. Children exposed to second-hand smoke are at a higher risk of developing middle ear effusions due to the irritation and inflammation caused by the toxins in the smoke. This can lead to recurrent ear infections and hearing issues in children. Option B) bacterial respiratory illnesses is incorrect because while second-hand smoke can increase the risk of respiratory infections, it specifically affects the upper respiratory tract more than the lower respiratory tract, which is commonly associated with bacterial infections. Option C) otitis externa is incorrect because this condition is usually caused by water exposure or trauma to the ear canal, not directly linked to second-hand smoke exposure. Option D) sinusitis is incorrect as well because second-hand smoke is not a direct cause of sinusitis. Sinusitis is more commonly associated with viral or bacterial infections and allergies. Educationally, it is essential for pediatric nurses to be aware of the detrimental effects of second-hand smoke on children's health to provide preventive education to families and promote a smoke-free environment for children. By understanding these associations, nurses can advocate for smoking cessation interventions and support families in creating a healthy and safe environment for children to thrive.

Correct Answer: D

Rationale: The correct answer is D) early infancy. Allergic rhinitis is often triggered by exposure to allergens during early childhood, typically before the age of 3. This period is critical because it is when the immune system is still developing and may become sensitized to allergens. Genetic predisposition plays a significant role in the development of allergic rhinitis, and early infancy is when genetically susceptible individuals are at the greatest risk of sensitization. Option A) early adolescence is incorrect because by this age, the immune system has already been exposed to various allergens, and sensitization may have occurred earlier in infancy. Option B) late adolescence is also incorrect as allergic rhinitis tends to manifest earlier in life, and the critical period for sensitization is not during late adolescence. Option C) school age is not the most critical period for the development of allergic rhinitis as sensitization typically occurs earlier, during infancy. Educationally, understanding the critical period for the development of allergic rhinitis is crucial for healthcare professionals working with pediatric populations. Recognizing the signs and symptoms of allergic rhinitis in infants and young children allows for early intervention and management to improve quality of life and prevent complications associated with untreated allergies. This knowledge also informs patient education efforts aimed at promoting allergen avoidance and appropriate treatment strategies.

Correct Answer: D

Rationale: In this question, the correct answer is D) 48%. The percentage of asthma in patients with allergic rhinitis is 48% because the question states that the percentage of allergic rhinitis in asthmatic patients is 78%. This implies that among asthmatic patients, 78% also have allergic rhinitis, leaving 22% with asthma but without allergic rhinitis. Therefore, among patients with allergic rhinitis, the remaining 22% have asthma, giving us a total of 78% + 22% = 100% of asthmatic patients. Now, let's analyze why the other options are incorrect: A) 18%: This percentage does not align with the information provided in the question and is not a logical deduction based on the given data. B) 28%: Similarly, this percentage does not match with the information provided and does not follow logically from the given data. C) 38%: This option is also incorrect as it does not reflect the relationship between allergic rhinitis and asthma as stated in the question stem. Educationally, this question helps reinforce the understanding of the co-existence of allergic rhinitis and asthma in patients. Understanding the comorbidity between these conditions is crucial for healthcare professionals, especially in the pediatric population where these conditions are common. By grasping the epidemiological aspects of these conditions, nurses can provide better care, anticipate complications, and implement appropriate management strategies for pediatric patients with allergic rhinitis and asthma.

Correct Answer: D

Rationale: In pediatric nursing, it is crucial to be able to recognize the indications of severe exacerbation of asthma to provide timely and appropriate care to children. In this case, the correct answer is D) PEF or FEV1 value <70% of personal best. This option is correct because a PEF (peak expiratory flow) or FEV1 (forced expiratory volume in 1 second) value less than 70% of the personal best indicates significant airway obstruction and poor asthma control. This measurement is a key indicator of asthma severity and response to treatment. Option A) breathlessness, Option B) accessory muscle use, and Option C) labored breathing are all common signs of severe asthma exacerbation. Children experiencing a severe asthma attack may exhibit these symptoms due to the narrowed airways and increased work of breathing. These signs indicate a need for immediate intervention and monitoring. Educational context: Understanding the signs of severe exacerbation of asthma is essential for pediatric nurses to provide prompt and effective care to children with asthma. Regular assessment of symptoms, including monitoring PEF or FEV1 values, can help nurses identify worsening asthma and intervene early to prevent complications. This knowledge is critical for managing pediatric asthma and promoting positive health outcomes for children with this chronic condition.

Correct Answer: D

Rationale: In pediatric nursing, understanding the features of well-controlled asthma is crucial for effective management. In the case of a 7-year-old boy, the correct answer is D) 2-4 exacerbations in the past year. This is because having 2-4 exacerbations indicates poorly controlled asthma, not well-controlled asthma. A) FEV1/FVC ratio >80% and B) FEV1 >80% of predicted are indicative of good lung function, which are features of well-controlled asthma. C) Daytime symptoms ≤2 days/week suggest good symptom control, also characteristic of well-controlled asthma. Educationally, knowing these features helps nurses assess and monitor asthma control in pediatric patients. Recognizing well-controlled asthma allows for appropriate adjustments in medication and management plans to maintain optimal health and quality of life for the child. Understanding these distinctions ensures that healthcare providers can provide the best care and support for pediatric patients with asthma.
