What is the main purpose of the initial assessment of a child with a suspected fracture?

Correct Answer: B

Rationale: The main purpose of the initial assessment of a child with a suspected fracture is to check for potential complications, such as neurovascular impairment, and to ensure appropriate treatment. Choice A is incorrect because determining the type of fracture usually requires imaging studies like X-rays, which may not be part of the initial assessment. Choice C is incorrect because identifying the cause of the injury is important for the history-taking part but may not be the main purpose of the initial assessment. Choice D is incorrect because long-term rehabilitation planning typically occurs after the acute phase of fracture management.

Correct Answer: D

Rationale: The priority assessment for a child with suspected appendicitis is 'Pain level.' Evaluating the pain level, particularly in the lower right quadrant, is crucial as it helps in determining the severity of the condition, leading to prompt diagnosis and treatment. Monitoring temperature, heart rate, and respiratory rate are important aspects of assessment; however, they are secondary to assessing the pain level in cases of suspected appendicitis. Pain assessment is key in diagnosing this condition since the classic presentation includes abdominal pain that often starts around the umbilicus and then localizes to the right lower quadrant.

Correct Answer: A

Rationale: The correct answer is A: Insulin administration. When a child is diagnosed with type 1 diabetes, insulin administration is a crucial intervention. Insulin helps regulate blood glucose levels by enabling cells to take in glucose from the bloodstream. Without sufficient insulin, blood glucose levels can become dangerously high, leading to various complications. Increased dietary fat intake (choice B) is not a recommended intervention for type 1 diabetes management, as it can contribute to weight gain and other health issues. Restricted fluid intake (choice C) is also not appropriate, as adequate hydration is essential for overall health. Routine physical examinations (choice D) are important but are not the primary intervention needed to manage type 1 diabetes.

Correct Answer: A

Rationale: The correct answer is minerals. Micronutrients are required by the body in smaller amounts compared to macronutrients like proteins and carbohydrates. Proteins are macronutrients necessary for growth and repair, not classified as micronutrients. Alcohols and carbohydrates are not classified as micronutrients either.

Correct Answer: B

Rationale: Nutrigenomics is the study of how diet affects gene expression, influencing health outcomes and disease risk. Epigenetics (choice A) involves changes in gene expression or cellular phenotype caused by mechanisms other than changes in the underlying DNA sequence. Genomics (choice C) is the study of an organism's entire genome. Genetics (choice D) is the study of heredity and the variation of inherited characteristics.

Correct Answer: A

Rationale: Corrected Rationale: Using a large sample size reduces the likelihood of chance variation affecting the results, providing more reliable data. Choice B is incorrect because the placebo effect is related to participants' beliefs, not sample size. Choice C is incorrect as double-blind refers to a method of reducing bias, not directly related to sample size. Choice D is incorrect because the similarity between the control and experimental groups is not solely dependent on sample size.

Correct Answer: A

Rationale: In managing lactose intolerance in a child, recommending lactose-free dairy products is crucial. These products help address the child's nutritional needs without causing symptoms related to lactose consumption. Choice B is incorrect because increasing dairy intake would exacerbate symptoms in a lactose-intolerant individual as they cannot digest lactose properly. Choice C, encouraging a high-fiber diet, is not directly related to managing lactose intolerance and may not address the primary issue of lactose malabsorption. Choice D, using oral probiotics only, may not be sufficient to address the child's nutritional needs in case of lactose intolerance as the main concern is avoiding lactose-containing products.

Correct Answer: A

Rationale: Checking skin turgor and mucous membranes is the appropriate method to assess hydration status in a child with vomiting and diarrhea. Skin turgor is an indicator of skin elasticity, which decreases when an individual is dehydrated. Mucous membranes, such as the inside of the mouth, can also show signs of dehydration like dryness. Measuring blood glucose levels (choice B) is not relevant to assessing hydration status in this scenario. Assessing heart rate and blood pressure (choice C) is important in evaluating the overall condition of a child but may not directly indicate hydration status. Evaluating bowel sounds (choice D) is more related to assessing gastrointestinal function rather than hydration status.

Correct Answer: B

Rationale: Dry mouth and lips are common signs of dehydration in infants. When an infant is dehydrated, the body conserves water, resulting in less urine production and concentrated urine. This leads to decreased frequency of urination rather than frequent urination, making choice A incorrect. Choice C, increased appetite, is not typically associated with dehydration in infants but rather with normal growth and development. Normal skin turgor, as mentioned in choice D, is a sign of hydration and not dehydration, making it an incorrect choice. Therefore, the correct answer is B, dry mouth and lips, which indicate a need for fluid replacement.
