The characteristic manifestation of pellagra is

Correct Answer: A

Rationale: Rationale: The correct answer is A) dermatitis. Pellagra is a disease caused by a deficiency of niacin (vitamin B3) and is characterized by the "3 Ds": dermatitis, diarrhea, and dementia. Dermatitis, specifically a photosensitive dermatitis, is a hallmark sign of pellagra, presenting as a scaly rash on areas exposed to sunlight. This skin manifestation is often one of the first symptoms to appear. Option B) diarrhea is another symptom of pellagra, but it is not the characteristic manifestation. Diarrhea usually occurs later in the progression of the disease. Option C) dementia is also a symptom of pellagra, but it typically occurs in the advanced stages of the disease and is not the characteristic manifestation. Option D) anorexia is a common symptom seen in various nutritional deficiencies but is not the characteristic manifestation of pellagra. Educational Context: Understanding the characteristic manifestations of pediatric gastrointestinal disorders is crucial for nurses and healthcare providers to recognize and manage these conditions effectively. Pellagra is a condition that can have serious consequences if not diagnosed and treated promptly. By identifying the key symptoms like dermatitis early on, healthcare professionals can intervene with appropriate nutritional support and prevent further complications. This question reinforces the importance of recognizing dermatitis as a key sign of pellagra, enabling healthcare providers to provide timely and effective care to pediatric patients with this condition.

Correct Answer: A

Rationale: In pediatric healthcare, understanding the correct dietary intake of essential nutrients like folate is crucial for ensuring optimal growth and development in infants. The correct answer to the question is A) 80 microgm/day. The Dietary Reference Intake (DRI) for folate in infants is lower compared to older children and adults due to their smaller size and metabolic needs. At eight months of age, infants typically rely on breast milk or formula as their primary source of nutrition. Both breast milk and infant formula are designed to provide the necessary nutrients for infants, including folate. Option B) 150 microgm/day, C) 200 microgm/day, and D) 300 microgm/day are higher than the recommended least reference dietary intake for an eight-month-old infant. Excessive intake of folate in infants can lead to potential adverse effects. Therefore, it is essential for healthcare providers and caregivers to follow the recommended guidelines to prevent complications related to nutrient imbalances. Educationally, this question highlights the importance of understanding age-specific nutritional requirements in pediatric patients. Healthcare professionals working with infants must be knowledgeable about appropriate dietary recommendations to promote healthy growth and development. By selecting the correct answer, healthcare providers can ensure they are providing evidence-based care that meets the unique needs of pediatric patients.

Correct Answer: A

Rationale: The correct answer is A) 0.5 microgm/day for the reference dietary intake of cobalamin for a healthy eight-month-old infant. Cobalamin, also known as Vitamin B12, is essential for neurological development and the production of red blood cells in infants. Option A is correct because infants require a small amount of cobalamin for their growth and development at this age. The recommended intake of cobalamin for infants is low compared to older children and adults due to their specific nutritional needs. Options B, C, and D are incorrect as they suggest higher daily intakes of cobalamin which are not appropriate for an eight-month-old infant. Excessive intake of cobalamin can lead to toxicity and potential health risks in infants. In an educational context, it is crucial for healthcare professionals, especially those working with pediatric populations, to have a clear understanding of the specific nutritional requirements for infants at different stages of development. This knowledge is essential for providing appropriate care and ensuring optimal growth and development in infants. Understanding the appropriate reference dietary intake of nutrients like cobalamin is vital for promoting the health and well-being of pediatric patients.

Correct Answer: D

Rationale: In understanding the question regarding the recognized causes of craniotabes in pediatric gastrointestinal disorders for the NCLEX exam, it is essential to delve into each option to provide a comprehensive rationale. Option A: Rickets is a recognized cause of craniotabes due to its impact on bone health and development. Rickets can lead to softening of the bones, including those in the skull, which can manifest as craniotabes. Option B: Syphilis can also cause craniotabes as the disease affects multiple organ systems, including bones. In infants born to mothers with untreated syphilis, craniotabes can develop as a result of the infection. Option C: In a normal newborn, craniotabes can be present as a transient condition due to the skull bones being soft and pliable during the early postnatal period. This is considered a normal variant and typically resolves on its own without intervention. Option D: Sotos syndrome is not a recognized cause of craniotabes. Sotos syndrome is a genetic disorder characterized by overgrowth during childhood, intellectual disability, and distinctive facial features. It does not typically present with craniotabes as a symptom. Educational Context: Understanding the differential causes of craniotabes is crucial for healthcare providers working with pediatric patients. Recognizing the various etiologies of craniotabes can aid in early diagnosis, appropriate treatment, and monitoring of affected children. This knowledge is pertinent for nurses, nurse practitioners, and other healthcare professionals caring for pediatric patients with gastrointestinal disorders.

Correct Answer: A

Rationale: In pediatric patients, a reduced 25-hydroxy vitamin D level is typically seen in individuals with vitamin D deficiency (Option A). This is because 25-hydroxy vitamin D is the major circulating form of vitamin D and its levels are used to assess overall vitamin D status in the body. Option B, autosomal recessive hypophosphatemic rickets, is characterized by low levels of phosphate in the blood leading to impaired bone mineralization, but it does not directly affect 25-hydroxy vitamin D levels. Similarly, Option C, autosomal dominant hypophosphatemic rickets, is a genetic disorder causing low phosphate levels, not directly impacting vitamin D levels. Option D, Fanconi syndrome, is a renal tubular disorder that can lead to various electrolyte imbalances, including phosphate wasting, but it does not specifically cause a reduction in 25-hydroxy vitamin D levels. Educationally, understanding the relationship between different pediatric gastrointestinal disorders and their impact on vitamin and mineral levels is crucial for nurses and healthcare professionals working with pediatric populations. Recognizing the specific manifestations of each disorder aids in accurate diagnosis, appropriate treatment, and improved patient outcomes.
