A toddler who has been hospitalized for vomiting due to gastroenteritis is sleeping and difficult to wake up. Assessment reveals vital signs of a regular heart rate of 230 beats per minute, respiratory rate of 30 per minute, BP of 84/52, and capillary refill time of 3 seconds. Which dysrhythmia does the nurse suspect in this child?

Correct Answer: B

Rationale: In this scenario, the correct answer is B) Supraventricular tachycardia (SVT). SVT is a common dysrhythmia in pediatric patients and is characterized by a rapid heart rate originating above the ventricles. The toddler's heart rate of 230 beats per minute, along with other symptoms such as difficulty waking up, low blood pressure, and prolonged capillary refill time, are indicative of SVT. Option A) Rapid atrial flutter is incorrect because atrial flutter typically presents with a regular but very fast atrial rate, not as rapid as seen in this case. Option C) Sinus bradycardia is also incorrect as it refers to a slow heart rate originating from the sinus node, which is not consistent with the toddler's presentation of a heart rate of 230 beats per minute. Option D) Rapid atrial fibrillation is incorrect because atrial fibrillation presents with an irregularly irregular heart rate pattern, unlike the regular rapid rate seen in this case. Educationally, understanding pediatric dysrhythmias is crucial for nurses caring for children, especially in acute care settings. Recognizing the signs and symptoms of SVT and other dysrhythmias promptly can lead to timely interventions and improved patient outcomes. Nurses need to be skilled in assessing vital signs, recognizing abnormal findings, and implementing appropriate interventions to manage dysrhythmias effectively in pediatric patients.

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: D

Rationale: In the case of an infant hospitalized for nonorganic failure to thrive, the most appropriate nursing action is maintaining a consistent, structured environment (option D). This is crucial because infants thrive on predictability, routine, and consistency, which can help reduce stress and anxiety levels. A consistent environment can provide a sense of security and stability for the infant, promoting trust and attachment with caregivers. Option A, encouraging the infant to hold a bottle, is not the most appropriate action as it focuses on a physical aspect rather than addressing the underlying emotional and developmental needs of the infant. Option B, keeping the infant on bed rest, is not suitable for promoting growth and development in an infant as it restricts movement and interaction. Option C, rotating caregivers for more stimulation, may disrupt the establishment of trust and consistency, which are essential for infants in building secure attachments. From an educational standpoint, understanding the importance of a consistent and structured environment for infants with nonorganic failure to thrive is crucial for nursing care. It highlights the significance of meeting not only the physical needs but also the emotional and developmental needs of infants in promoting optimal growth and well-being. By prioritizing a stable environment, nurses can support the infant's overall health and development effectively.

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.
