All the following statements concerning breast milk are true EXCEPT

Correct Answer: D

Rationale: In this question, option D is the correct answer. The rationale behind this is that cow's milk is not a good source of bioavailable iron for infants. In fact, cow's milk can lead to iron deficiency in infants due to its low iron content and the presence of certain proteins that can inhibit iron absorption. Option A is true because breast milk indeed provides optimal protein intake for children, containing the right balance of proteins necessary for their growth and development. Option B is also true as iron in breast milk is more easily absorbed by the infant's body compared to iron from animal sources, making it a superior source of iron for infants. Option C is incorrect as iron supplements actually do not interfere with zinc absorption. It is important to educate about the benefits of breast milk as the ideal nutrition for infants due to its perfect composition of nutrients tailored for their needs. Understanding the unique properties of breast milk can help healthcare professionals and parents make informed decisions regarding infant nutrition.

Correct Answer: C

Rationale: The correct answer is C) 110 g/L for children 12-14 years. This hemoglobin cutoff value is used to define anemia in this specific age group. Anemia is a condition characterized by a lower than normal level of red blood cells or hemoglobin in the blood, which can lead to symptoms such as fatigue, weakness, and pallor. Option A) 120 g/L for children 6-59 months is incorrect because the cutoff value for anemia in this age group is typically lower, around 110 g/L. Option B) 115 g/L for children 5-11 years is incorrect as the cutoff value for anemia in this age group is usually around 110 g/L as well. Option D) 120 g/L for men is incorrect as this value is specific to adult men and not applicable to children. Understanding the correct hemoglobin cutoff values for anemia in different age groups is crucial in pediatric nursing practice. It helps healthcare providers to accurately diagnose and treat anemia in children, ensuring optimal health outcomes. Regular monitoring of hemoglobin levels is essential in pediatric care to detect and manage anemia early.

Correct Answer: D

Rationale: In malnutrition, the outward sign of cell damage is wasting (Option D). Wasting refers to the severe loss of muscle and fat tissue due to inadequate nutrient intake. This is a characteristic feature of protein-energy malnutrition. Option A, edema, is the accumulation of fluid in tissues and occurs in conditions like kwashiorkor, which is a form of severe acute malnutrition characterized by edema. However, edema is not the primary outward sign of cell damage in malnutrition. Option B, hepatomegaly, refers to an enlarged liver and can be seen in conditions like liver disease or infection. While liver damage can occur in malnutrition, hepatomegaly is not the most prominent outward sign of cell damage in this context. Option C, facial appearance, can be affected in malnutrition, leading to a gaunt or sunken appearance. However, this is more of a general physical manifestation and not a direct sign of cell damage. Understanding these distinctions is crucial in pediatric nursing practice, especially when assessing and managing malnourished children. Recognizing wasting as a sign of severe malnutrition can prompt timely interventions to address nutritional deficiencies and prevent further complications.

Correct Answer: D

Rationale: In pediatric malnutrition, particularly during the stabilization phase, providing essential trace elements is crucial for the recovery and overall health of the child. In this context, the correct answer is D) zinc. Zinc plays a vital role in immune function, wound healing, and growth, making it essential during the stabilization phase of malnutrition. Zinc deficiency is common in malnourished children, and supplementing it helps in reversing growth stunting, immune system impairment, and other complications associated with malnutrition. Now, let's discuss why the other options are incorrect: A) Iron: While iron is important for red blood cell formation, it is not typically a priority during the stabilization phase of malnutrition unless the child has been diagnosed with iron deficiency anemia. B) Vitamin A: Although vitamin A is crucial for vision, immune function, and cell growth, it is not a trace element and is usually supplemented during the rehabilitation phase of malnutrition. C) Folate: Folate is a B-vitamin necessary for cell division and growth, but it is not typically prioritized during the stabilization phase of malnutrition compared to zinc. Educational Context: Understanding the specific nutritional needs of malnourished children is essential for healthcare providers, especially those preparing for exams like the NCLEX. Knowing which trace elements are crucial during different phases of malnutrition can help in providing targeted interventions and improving patient outcomes. Mastery of this knowledge ensures safe and effective pediatric care, making it a vital concept for nursing students and professionals to grasp.

Correct Answer: A

Rationale: In refeeding syndrome, when a malnourished individual undergoes rapid refeeding, there is a shift from fat to carbohydrate metabolism, leading to increased insulin secretion and subsequent intracellular uptake of electrolytes. This shift can result in hypophosphatemia, which is the main cause of thrombocytopenia in refeeding syndrome. Option A, hypophosphatemia, is correct because low serum phosphate levels can lead to impaired platelet function and decreased platelet count, causing thrombocytopenia in refeeding syndrome. Option B, hypokalemia, is incorrect because while electrolyte imbalances like hypokalemia can occur in refeeding syndrome, they are not the primary cause of thrombocytopenia in this condition. Option C, hypomagnesemia, is incorrect as well. Although magnesium deficiency can contribute to cardiac arrhythmias in refeeding syndrome, it is not the main factor leading to thrombocytopenia. Option D, thiamine deficiency, is also incorrect. Thiamine deficiency can result in Wernicke's encephalopathy in malnourished individuals, but it is not directly linked to thrombocytopenia in refeeding syndrome. Understanding the pathophysiology of refeeding syndrome and its impact on electrolyte balance and organ function is crucial for nurses and healthcare providers caring for malnourished pediatric patients. Recognizing the role of hypophosphatemia in thrombocytopenia can guide appropriate monitoring and treatment strategies to prevent complications in these vulnerable populations.
