Rationale: Absent breath sounds on the affected side are a primary symptom of congenital diaphragmatic hernia. Cyanosis, bradycardia, and tachypnea may also be present but are not the primary symptom. Cyanosis is a bluish discoloration of the skin due to poor oxygenation, bradycardia is a slower than normal heart rate, and tachypnea is rapid breathing.

Correct Answer: C

Rationale: Excessive frothy saliva is a hallmark sign of tracheoesophageal fistula. The abnormal connection between the esophagus and trachea causes difficulty in swallowing, leading to an accumulation of saliva in the mouth. This symptom is crucial for early identification and management of tracheoesophageal fistula. Choices A, B, and D are incorrect as they are not specific indicators of tracheoesophageal fistula.

Correct Answer: B

Rationale: The correct answer is B: All are correct. High-fiber foods like oranges, lima beans, baked beans, and raisin bran cereal are effective in preventing constipation. Oranges are a good source of fiber, lima beans and baked beans are high in fiber content, and raisin bran cereal is also rich in fiber. Bananas, which are not listed but could be considered by some as a high-fiber food, are actually low in fiber and may not be as effective in preventing constipation. Therefore, the nurse should include all the options provided in the teaching to help prevent constipation effectively.

Correct Answer: C

Rationale: The most important intervention in managing a child with sickle cell crisis is the administration of pain relief. During a sickle cell crisis, severe pain is a prominent symptom due to vaso-occlusive episodes. Effective pain management, along with adequate hydration and oxygen therapy, is crucial in treating a sickle cell crisis and preventing further complications. Choice A, the administration of iron supplements, is not the priority during a sickle cell crisis. Iron supplements are typically used to manage anemia in individuals with sickle cell disease but are not the primary intervention during a crisis. Choice B, the initiation of a high-calorie diet, is not the most critical intervention during a sickle cell crisis. While proper nutrition is important in managing sickle cell disease, it is not the immediate priority during a crisis. Choice D, limiting fluid intake, is not recommended during a sickle cell crisis. Hydration is essential in managing sickle cell crisis to prevent complications like dehydration and further vaso-occlusive episodes.

Correct Answer: A

Rationale: The Ortolani sign is a specific maneuver used during physical examination to detect hip instability or dislocation in infants. A positive Ortolani sign, where the hip is felt to slip back into the socket, is indicative of developmental dysplasia of the hip, a condition that can lead to long-term disability if not treated early. Romberg sign is used to assess sensory ataxia, Trendelenburg sign indicates weakness of the hip abductor muscles, and Gower's sign is seen in children with proximal muscle weakness climbing up their own body from a supine position due to conditions like muscular dystrophy.
