Common causes of jaundice in a 12-hour-old neonate include:

Correct Answer: B

Rationale: In a 12-hour-old neonate, common causes of jaundice include Rhesus isoimmunisation (Option B). This occurs when the mother is Rh-negative and the baby is Rh-positive, leading to the mother's antibodies attacking the baby's red blood cells, causing jaundice. Option A, Glucose-6-phosphate dehydrogenase deficiency, usually presents later in life and is not a common cause of jaundice in a 12-hour-old neonate. Option C, Crigler-Najjar syndrome type II, is a rare genetic disorder that typically manifests later in infancy or childhood, not in the first 12 hours of life. Option D, Choledochal cyst, is a congenital condition affecting the bile ducts and is not a common cause of jaundice in a neonate within the first 12 hours of life. Understanding the causes of jaundice in neonates is crucial for nurses and healthcare providers working in pediatric settings. Recognizing the correct etiology of jaundice helps in appropriate management and timely interventions to prevent complications. Rhesus isoimmunisation is an important condition to identify early to provide necessary treatment and support to the neonate and family. This knowledge is essential for nurses caring for newborns and infants to ensure optimal outcomes and promote family education and support.

Correct Answer: C

Rationale: In the context of pediatric patients with recurrent abdominal pain, the correct answer is C) Functional cause. Recurrent abdominal pain in children is a common complaint and often has a functional etiology, meaning there is no identifiable organic cause. This can be due to factors such as stress, anxiety, or changes in routine. It is important for healthcare providers to consider functional causes as a potential reason for abdominal pain in children, as addressing these underlying issues can lead to effective management and relief of symptoms. Option A) Gilbert syndrome is a genetic liver disorder that typically presents with intermittent episodes of jaundice and fatigue, not recurrent abdominal pain. Option B) Chronic constipation can cause abdominal discomfort, but it is usually associated with a different set of symptoms and is not a common cause of recurrent abdominal pain in children. Option D) Gastric ulcer is a serious condition that can cause abdominal pain, but it is less common in pediatric patients and would typically present with other symptoms such as nausea, vomiting, or blood in the stool. Educationally, understanding the common causes of recurrent abdominal pain in pediatric patients is crucial for healthcare providers, especially in a nursing context. By recognizing that functional causes are often at the root of this complaint, nurses can provide holistic care that addresses not only physical symptoms but also emotional and psychological factors that may be contributing to the pain. This knowledge helps nurses advocate for appropriate assessment, management, and support for pediatric patients experiencing recurrent abdominal pain.

Correct Answer: D

Rationale: In this question, the correct answer is D) Ventricular septal defect. Evidence of increased pulmonary flow is associated with a ventricular septal defect (VSD) in pediatric cardiovascular conditions. A VSD allows blood to flow from the left ventricle to the right ventricle, leading to increased blood volume in the right side of the heart and subsequently increased pulmonary blood flow. This results in symptoms such as a loud holosystolic murmur and signs of congestive heart failure in infants. Now, let's analyze why the other options are incorrect: A) Coarctation of the aorta: This condition involves a narrowing of the aorta, leading to increased blood pressure in the upper extremities and decreased blood flow to the lower extremities. It is not associated with increased pulmonary flow. B) Fallot's tetralogy: This congenital heart defect consists of four abnormalities, including pulmonary stenosis, right ventricular hypertrophy, VSD, and an overriding aorta. It is not directly associated with increased pulmonary flow. C) Pneumocystis infection: This is a type of pneumonia caused by Pneumocystis jirovecii, which primarily affects immunocompromised individuals. It is not related to increased pulmonary flow in the context of pediatric cardiovascular conditions. Educational context: Understanding the hemodynamic consequences of different congenital heart defects is crucial for nurses caring for pediatric patients with cardiovascular conditions. Recognizing the association between a VSD and increased pulmonary flow helps nurses provide appropriate care and anticipate potential complications in these patients.

Correct Answer: D

Rationale: In this question, the correct answer is option D) Meningomyelocele. Elevated maternal serum alpha-fetoprotein (AFP) levels are associated with neural tube defects such as meningomyelocele. AFP is produced by the fetal liver and yolk sac, and elevated levels can indicate issues with the developing fetus. Option A) Trisomy 21 is incorrect because it is associated with elevated maternal serum human chorionic gonadotropin (hCG), not AFP. Option B) Exomphalos is incorrect because it is associated with defects in the abdominal wall, not with elevated AFP levels. Option C) Marfan syndrome is incorrect as it is a genetic connective tissue disorder and is not related to elevated AFP levels. In the context of pediatric nursing, understanding the significance of maternal serum AFP levels can help nurses in assessing the risk of neural tube defects in the fetus. This knowledge is crucial for providing appropriate prenatal care and counseling to families. It also highlights the importance of early detection and intervention in cases of neural tube defects.

Correct Answer: A

Rationale: The correct answer is A) Selenium deficiency. Total parenteral nutrition (TPN) is a method of providing nutrition intravenously to patients who are unable to tolerate oral or enteral feeding. Long-term TPN administration can lead to selenium deficiency due to the lack of this essential mineral in TPN solutions. Selenium is crucial for antioxidant defense and proper immune function, and deficiency can result in complications such as cardiac dysfunction and muscle weakness. Option B) Abnormal liver function tests may occur with long-term TPN administration, but it is not a direct complication of TPN itself. Liver issues can arise due to factors like infection, metabolic disorders, or medications, rather than selenium deficiency. Option C) Osteopaenia, or decreased bone density, is not a common complication of long-term TPN administration. Calcium and vitamin D deficiencies are more closely linked to osteopaenia than selenium deficiency. Option D) Renal failure is not a typical complication of long-term TPN administration. Renal failure is more commonly associated with conditions like hypertension, diabetes, or certain medications, rather than selenium deficiency from TPN. Educationally, understanding the potential complications of long-term TPN administration is crucial for healthcare professionals caring for patients on TPN. Recognizing the signs and symptoms of selenium deficiency and other nutrient deficiencies can aid in early intervention and prevention of serious complications. Monitoring and managing nutritional status are essential aspects of providing care for patients receiving TPN to optimize outcomes and minimize risks.
