A nurse is caring for a child who has otitis media with effusion. The nurse should identify which of the following manifestations indicates a tympanic membrane rupture.

Choice A: Distended neck veins are not a clinical manifestation of pyloric stenosis, which is a condition that causes the narrowing of the pylorus, which is the opening between the stomach and the small intestine. Distended neck veins are a sign of increased venous pressure, which can occur in conditions that affect the right side of the heart or cause fluid overload.

Choice B: Rigid abdomen is not a clinical manifestation of pyloric stenosis, but rather a sign of peritonitis, which is inflammation of the peritoneum, which is the membrane that lines the abdominal cavity. Peritonitis can be caused by infection, perforation, or trauma to any abdominal organ. A rigid abdomen indicates severe pain and inflammation in the abdominal cavity.

Choice C: Projectile vomiting is a clinical manifestation of pyloric stenosis, as it indicates forceful expulsion of stomach contents due to obstruction at the pylorus. Projectile vomiting can occur shortly after feeding and may contain undigested milk or formula. Projectile vomiting can cause dehydration, electrolyte imbalance, or weight loss.

Choice D: Red currant jelly stools are not a clinical manifestation of pyloric stenosis, but rather a sign of intussusception, which is a condition that causes telescoping of one segment of bowel into another. Intussusception can cause obstruction and ischemia of the bowel and lead to bleeding and necrosis. Red currant jelly stools indicate blood and mucus in the stool.

Choice A: This instruction is incorrect, as withholding insulin dose if feeling nauseous can cause hyperglycemia, which is high blood sugar, and diabetic ketoacidosis, which is a life-threatening condition that occurs when the body breaks down fat for energy and produces ketones. Ketones are acidic substances that can cause nausea, vomiting, abdominal pain, dehydration, or coma. The child should take their insulin dose as prescribed and monitor their blood sugar levels more frequently when they are sick.

Choice B: This instruction is unnecessary, as notifying the provider if blood glucose levels are within normal parameters does not require any action or intervention. The child and the parents should notify the provider if blood glucose levels are above or below the target range, which is usually 70 to 180 mg/dL for children with type 1 diabetes mellitus. The child and the parents should also notify the provider if they have any signs or symptoms of hypoglycemia, hyperglycemia, or diabetic ketoacidosis.

Choice C: This instruction is incorrect, as limiting fluid intake during mealtime can cause dehydration, which can worsen the symptoms and complications of type 1 diabetes mellitus. Dehydration can cause increased thirst, dry mouth, fatigue, headache, or dizziness. The child should drink plenty of fluids during meal time and throughout the day to hydrate their body and flush out excess glucose and ketones.

Choice D: This instruction is correct, as testing the urine for ketones can help detect diabetic ketoacidosis, which is a life-threatening condition that occurs when the body breaks down fat for energy and produces ketones. Ketones are acidic substances that can cause nausea, vomiting, abdominal pain, dehydration, or coma. The child should test their urine for ketones when their blood sugar levels are above 240 mg/dL or when they are sick. The child and the parents should notify the provider if the urine test shows moderate or large amounts of ketones.
