Persons with up to 70% prevalence of peculiar facial anatomy are considered risk factors for obstructive sleep apnea EXCEPT

Correct Answer: D

Rationale: In this question from the Free Pediatric CCRN Practice Questions exam, the correct answer is D) hypothyroidism. Hypothyroidism is not typically associated with peculiar facial anatomy, which is a risk factor for obstructive sleep apnea. A) Hypotonia can contribute to airway obstruction, leading to obstructive sleep apnea in pediatric patients. B) Developmental delay can affect the structural development of the face and airway, increasing the risk of obstructive sleep apnea. C) Central adiposity, or excess fat around the neck and throat area, can put pressure on the airway, contributing to obstructive sleep apnea. Educationally, understanding risk factors for obstructive sleep apnea in pediatric patients is crucial for nurses working in critical care settings. Recognizing these risk factors can aid in early identification and intervention, improving patient outcomes. By knowing which conditions are associated with obstructive sleep apnea, nurses can provide targeted care and support to these vulnerable patients.

Correct Answer: D

Rationale: In the fetal period of development, various key milestones occur as the baby grows and matures in the womb. In this question, the correct answer is D) 26 weeks - face clearly recognizable. This is incorrect because by 26 weeks, the face is not yet fully developed to be clearly recognizable. While facial features are forming during this time, they are not yet distinct enough to be easily identifiable. Option A) 10 weeks - midgut returns to abdomen is correct as by 10 weeks, the midgut, which initially herniates into the umbilical cord, should have returned to the abdominal cavity. Option B) 12 weeks - external genitalia formed is correct as by 12 weeks, the external genitalia should have developed and can be visualized. Option C) 24 weeks - surfactant production begun is correct as surfactant production in the lungs typically begins around 24 weeks, playing a crucial role in lung maturation and function. Understanding the timeline of fetal development is essential for healthcare professionals working with pediatric patients. This knowledge helps in assessing developmental milestones, identifying potential issues, and providing appropriate care and support for both the child and their family.

Correct Answer: C

Rationale: In children, the most common cause of obstructive sleep apnea is adenotonsillar hypertrophy (Option C). Adenotonsillar hypertrophy refers to enlarged tonsils and adenoids, which can obstruct the airway during sleep, leading to breathing pauses and disrupted sleep patterns. This condition is prevalent in children due to the anatomical size of their airways relative to the size of their tonsils and adenoids. Option A, obesity, can also contribute to sleep apnea in children, but it is not the most common cause. Obesity can lead to increased soft tissue around the airway, contributing to obstruction during sleep. Option B, allergies, can cause nasal congestion and inflammation, but it is not the primary cause of obstructive sleep apnea in children. Option D, pharyngeal reactive edema due to gastroesophageal reflux, is less common than adenotonsillar hypertrophy in causing obstructive sleep apnea in children. While gastroesophageal reflux can cause inflammation in the throat, leading to some airway obstruction, it is not as prevalent as adenotonsillar hypertrophy. Educationally, understanding the common causes of obstructive sleep apnea in children is crucial for healthcare providers working with pediatric patients. Recognizing adenotonsillar hypertrophy as the primary cause can guide clinicians in appropriate assessment, management, and referral for children presenting with symptoms of sleep-disordered breathing. This knowledge enhances the quality of care provided to children with obstructive sleep apnea, leading to better outcomes and improved quality of life.

Correct Answer: D

Rationale: In this scenario, the correct answer is D) fine motor and symbolic thought. Building a tower by a 22-month-old child involves fine motor skills such as grasping, stacking, and manipulating objects. Additionally, it requires symbolic thought, as the child is using the blocks as symbols to represent a structure. Option A) visual-motor coordination is not the most critical aspect when building a tower with blocks. While visual-motor coordination is important for tasks like drawing or threading beads, it is not the primary skill at play in tower building. Option B) using objects and actions in combination is too broad and does not specifically address the fine motor skills and symbolic thought required for tower building. Option C) gross motor skills are related to larger movements of the body, such as walking or jumping. These skills are not as directly involved in the precise movements needed for building a tower with blocks. In an educational context, understanding the developmental milestones and skills required for tasks like building a tower can help educators assess a child's progress and provide appropriate support and guidance. By recognizing that tower building involves fine motor skills and symbolic thought, educators can create activities that specifically target these areas of development in young children.

Correct Answer: D

Rationale: Obstructive sleep apnea (OSA) is characterized by episodes of upper airway obstruction during sleep, leading to apnea (cessation of breathing) or hypopnea (reduced airflow). The correct answer, option D, "2-30% O2 desaturation," is incompatible with the definition of OSA because significant oxygen desaturation, usually greater than 3-4%, is a hallmark feature of OSA, not a mild desaturation range of 2-30%. Option A, "episodes of prolonged upper airway obstruction," is compatible with OSA as this obstruction leads to breathing difficulties during sleep. Option B, "repeated apnea," is also compatible as OSA is characterized by recurrent episodes of apnea/hypopnea. Option C, "2-30% reduction in airflow," is also compatible as reduced airflow is a key feature of OSA contributing to breathing difficulties and hypoxia. In an educational context, understanding the defining characteristics of OSA is crucial for healthcare providers, especially those caring for pediatric patients who may be at risk for this condition. Recognizing the symptoms and diagnostic criteria for OSA can lead to timely intervention and management to improve the child's overall health and quality of life.
