Ciprofloxacin is the drug of choice for the treatment of

Correct Answer: C

Rationale: Ciprofloxacin is the drug of choice for the treatment of Campylobacter jejuni infections because it is effective against this particular bacterium. Campylobacter jejuni is a common cause of bacterial gastroenteritis in children and adults, and ciprofloxacin has shown good efficacy in treating these infections. Option A) Salmonella: Ciprofloxacin is not typically the first-line treatment for Salmonella infections. In fact, the use of ciprofloxacin in Salmonella infections is discouraged due to concerns of increasing antibiotic resistance. Option B) Shigella: While ciprofloxacin may be used in some cases of Shigella infections, resistance to this drug is becoming more common. Other antibiotics like azithromycin or ceftriaxone are often preferred for treating Shigella infections. Option D) Clostridium difficile: Ciprofloxacin is not the drug of choice for Clostridium difficile infections. The primary treatment for C. difficile infections involves stopping the causative antibiotic, supportive care, and in some cases, the use of specific antibiotics like metronidazole or vancomycin. Educational context: Understanding the appropriate use of antibiotics in treating pediatric gastrointestinal infections is crucial to prevent antibiotic resistance and ensure effective treatment. By knowing the specific pathogens targeted by each antibiotic, healthcare providers can make informed decisions to provide the best care for their patients.

Correct Answer: B

Rationale: The correct answer is B) serum lipase. Serum lipase is the preferred test for diagnosing acute pancreatitis because it is more specific and remains elevated for a longer period compared to serum amylase. Lipase is released from the pancreas into the blood when the pancreas is inflamed, making it a more reliable marker for pancreatic injury. Elevated serum lipase levels are a key indicator of acute pancreatitis. Option A) serum amylase is a common test for pancreatitis, but it is less specific and can be elevated in conditions other than pancreatitis, such as salivary gland disorders. Option C) hyperglycemia is a symptom of uncontrolled diabetes rather than a specific test for acute pancreatitis. Option D) elevated y-glutamyl transpeptidase is associated with liver and biliary tract disorders, not acute pancreatitis. Educationally, understanding the appropriate diagnostic tests for acute pancreatitis is crucial for nurses and healthcare professionals caring for pediatric patients. This knowledge ensures timely and accurate diagnosis, leading to appropriate treatment interventions and improved patient outcomes. Regular review of these concepts will enhance clinical decision-making skills and promote quality care delivery in pediatric gastrointestinal health.

Correct Answer: D

Rationale: The correct answer is D) Zellweger syndrome. Zellweger syndrome is a rare genetic disorder that affects how the body breaks down fats. It is characterized by the absence or malfunction of peroxisomes, which are responsible for various metabolic functions. Hepatic transplantation can correct the metabolic error in Zellweger syndrome because it can provide functional peroxisomes to the patient's body, improving their ability to break down fats and potentially improving their overall health outcomes. Option A) Tyrosinemia, Option B) Galactosemia, and Option C) Hereditary fructose intolerance are all metabolic disorders that involve specific enzyme deficiencies or errors in metabolic pathways related to the metabolism of amino acids, sugars, or fructose, respectively. While liver transplantation can be beneficial in certain cases of these disorders, it is not a primary treatment option or a cure due to the complex nature of these metabolic errors. Educational Context: Understanding the impact of hepatic transplantation on metabolic disorders is crucial for healthcare providers, especially in pediatric patients with advanced liver disease. This knowledge helps in providing appropriate care, counseling families on treatment options, and managing expectations regarding the outcomes of transplantation in different metabolic disorders. It also highlights the importance of interdisciplinary collaboration between transplant specialists and metabolic experts in managing complex cases effectively.

Correct Answer: D

Rationale: Neonatal iron storage disease (NISD), or neonatal hemochromatosis, is a rare condition characterized by excessive iron accumulation in the liver and other organs. In this case, option D, hyperglycemia, is incorrect. The correct answer is D) hyperglycemia because neonatal iron storage disease is not typically associated with elevated blood sugar levels. A) Hypoprothrombinemia is incorrect as it is a characteristic of NISD due to liver dysfunction leading to decreased synthesis of clotting factors. B) Hypoalbuminemia is incorrect as it can occur due to liver damage in NISD, leading to reduced albumin production. C) Hyperferritinemia is correct as elevated ferritin levels are a hallmark of iron overload seen in NISD. Educationally, understanding the clinical manifestations of neonatal iron storage disease is crucial for nurses and healthcare providers caring for infants with this condition. Recognizing the signs and symptoms, such as hyperferritinemia and hypoprothrombinemia, can aid in early diagnosis and appropriate management of the disease. This knowledge is essential for providing safe and effective care to pediatric patients with gastrointestinal disorders.

Correct Answer: C

Rationale: In pediatric nursing, understanding HBV serologic markers is crucial for the assessment and management of hepatitis B virus infections. In this question, option C is the correct answer. HBc antigens are not detected in persons immunized with the hepatitis B vaccine. This is because the vaccine contains only the surface antigen (HBsAg) and not the core antigen (HBcAg). Option A is incorrect because HBsAg is indeed the first marker to appear in acute hepatitis B infection. Option B is incorrect as anti-HBc is a key marker of infection, indicating past or ongoing infection. Option D is incorrect as HBeAg is a marker of high infectivity, indicating active viral replication and increased risk of transmission. Educationally, this question highlights the importance of understanding HBV serologic markers in pediatric patients. It emphasizes the need for nurses to correctly interpret these markers to provide appropriate care and education to patients and their families. This knowledge is essential for preventing the spread of hepatitis B and ensuring optimal health outcomes for pediatric patients.
