Nurse Betina should begin screening for lead poisoning when a child reaches which age?

Correct Answer: B

Rationale: In pediatrics, screening for lead poisoning is crucial to prevent long-term health consequences. The correct answer is B) 12 months. At this age, children are more likely to come into contact with environmental sources of lead through hand-to-mouth behaviors. Screening at 12 months allows for early detection and intervention, which is vital in preventing lead poisoning-related developmental delays and cognitive impairments. Option A) 6 months is too early for routine lead screening as the risk of exposure may not be as significant at this age. Option C) 18 months and D) 24 months are too late to initiate screening, as lead exposure and poisoning can occur earlier and have detrimental effects on a child's health and development. Educationally, understanding the rationale behind the timing of lead screening in pediatrics is essential for nurses and healthcare providers working with children. It highlights the importance of early detection and intervention in mitigating the effects of lead poisoning, emphasizing the role healthcare professionals play in safeguarding children's health. By knowing when to start screening and why, nurses can advocate for preventive measures and provide appropriate care to promote optimal child health outcomes.

Correct Answer: C

Rationale: In caring for a child with Down syndrome, it is crucial to assess the individual child's current developmental level and plan care accordingly. Option C is the correct answer because children with Down syndrome can have a wide range of developmental abilities and challenges. By assessing the child's specific developmental level, the nurse can tailor interventions to meet the child where they are at and support their individual needs effectively. Option A is incorrect because assuming the child's developmental level based solely on chronological age can overlook the unique developmental profile of a child with Down syndrome. Option B is also incorrect as it generalizes developmental delays without considering the variability in abilities seen in children with Down syndrome. Option D is not appropriate as it dismisses the child's capacity to understand and learn, which is not aligned with a person-centered approach to care. In an educational context, this question highlights the importance of individualized care planning for children with developmental differences like Down syndrome. It emphasizes the need for healthcare providers to assess each child's unique needs and abilities to provide effective and person-centered care. Understanding the complexities of caring for pediatric patients with special needs is essential for healthcare professionals working in diverse clinical settings.

Correct Answer: A

Rationale: In pediatric pharmacology, it is crucial to understand developmental milestones and readiness when addressing issues like toilet training. The correct answer, A) Developmental readiness of the child, is the most important factor to stress to Sheena as she considers toilet training her 22-month-old child. At this age, children vary in their physical, cognitive, and emotional development, and readiness for toilet training differs from child to child. Emphasizing the child's developmental readiness ensures that toilet training is approached at an appropriate time when the child can understand and participate in the process effectively. Option B, Consistency in approach, while important in toilet training, is not as crucial as ensuring the child is developmentally ready. Consistency will indeed be necessary once training begins, but if the child is not ready, it may lead to frustration and setbacks. Option C, The mother’s positive attitude, is important for creating a supportive environment, but it is not the most critical factor to stress. Positive attitude alone cannot replace the child's developmental readiness for successful toilet training. Option D, Developmental level of the child’s peers, is not the most important factor to stress to the mother. While peer influence can play a role in some developmental aspects, it is not as significant as the child's individual readiness for toilet training. Educationally, understanding the importance of considering developmental readiness in pediatric care is essential for nursing practice. It ensures that interventions are tailored to the individual child's needs, promoting successful outcomes and avoiding unnecessary stress for both the child and the caregiver. By emphasizing developmental readiness in scenarios like toilet training, nurses can support families in making informed decisions that align with their child's unique developmental stage.

Correct Answer: A

Rationale: In this scenario, the correct answer is A) Iron-rich formula and baby food. The rationale behind this is that after 5 months, breast milk alone may not provide sufficient iron for the infant's growth and development. Iron-rich formula can help meet the baby's iron needs as they transition from breast milk. Baby food is also important at this stage to introduce new textures and flavors to the infant's diet as they start weaning off breast milk. Option B) Whole milk is not recommended for infants under 1 year of age as it can be difficult for their digestive system to handle. Option C) Skim milk is also not appropriate for infants as it lacks essential fats and nutrients necessary for their growth. Option D) Iron-rich formula only would not provide the variety of nutrients and textures needed for the baby's development at this stage. In an educational context, it is crucial for nurses to understand the nutritional needs of infants at different stages of development. By providing accurate and evidence-based information to mothers, nurses can support them in making informed decisions about their child's diet and ensure optimal growth and development. This question highlights the importance of appropriate feeding practices during the weaning period for infants.

Correct Answer: D

Rationale: In this scenario, option D, "History of steroid-dependent asthma," is the correct answer indicating a child is at risk for a severe asthma exacerbation. Children with steroid-dependent asthma have a history of severe and recurrent asthma attacks, requiring long-term steroid therapy. This places them at higher risk for exacerbations due to the chronic nature of their condition and potential for poor asthma control. Option A, "Oxygen saturation of 95%," may seem like a good sign, but in asthma exacerbations, oxygen saturation can initially be maintained before dropping rapidly during a severe attack. Therefore, a child with a history of severe asthma exacerbations may still be at risk despite a seemingly normal oxygen saturation level. Option B, "Mild work of breathing," and option C, "Absence of intercostals or substernal retractions," both suggest a lack of significant respiratory distress. However, in severe asthma exacerbations, children may not exhibit these signs until the condition rapidly deteriorates. This emphasizes the importance of considering the child's medical history and risk factors for predicting severe asthma exacerbations. Educationally, this question highlights the critical role of recognizing risk factors in pediatric asthma management. Understanding a child's medical history, especially in chronic conditions like asthma, can help healthcare providers anticipate and prevent severe exacerbations. It also underscores the need for proactive monitoring and early intervention in children with a history of severe asthma to prevent potentially life-threatening situations.
