What is the most important intervention in the management of a child with sickle cell crisis?

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: B

Rationale: The most appropriate action for a child with epistaxis is to pinch the nose and lean forward. This technique helps stop the bleeding and prevent aspiration of blood. By applying pressure to the bleeding vessels and allowing the blood to drain out of the nostrils instead of being swallowed, the risk of nausea and airway obstruction is reduced. Having the child lie flat (Choice A) may lead to blood flowing down the throat, causing potential choking. Applying a warm compress (Choice C) is not typically recommended for epistaxis as cold compresses are more effective. Encouraging deep breathing (Choice D) is not directly related to managing epistaxis.

Correct Answer: D

Rationale: Mid-upper arm circumference is a good indicator of muscle mass and fat stores, reflecting a child's nutritional status. It is particularly useful in assessing malnutrition, as it is less affected by fluid retention or dehydration compared to other anthropometric measurements. Weight can fluctuate due to factors like hydration status, making it less reliable as a sole indicator of nutritional status. Height reflects growth but may not directly indicate current nutritional status. Head circumference is more related to brain growth and development rather than overall nutritional status.

Correct Answer: C

Rationale: The correct answer is C: Give epinephrine. Administering epinephrine is the first and most critical step in treating anaphylaxis. Epinephrine rapidly reverses the symptoms of anaphylaxis, including airway swelling, hypotension, and shock. Delaying administration can lead to severe complications or death, making it essential in emergency treatment. Choice A, administering oxygen, might be necessary but should not delay the administration of epinephrine. Starting an IV line (Choice B) is important for further treatment but not the initial step. Monitoring vital signs (Choice D) is essential but comes after administering epinephrine to stabilize the child.

Correct Answer: C

Rationale: The primary goal in treating nephrotic syndrome in children is to reduce proteinuria. Nephrotic syndrome is characterized by proteinuria, leading to hypoalbuminemia and edema. By reducing proteinuria, kidney damage can be minimized, and symptoms can be managed effectively. Decreasing urine output (Choice A) is not the primary goal, as it does not address the underlying issue of protein loss. Increasing serum albumin (Choice B) is a consequence of reducing proteinuria rather than the primary goal. Increasing blood pressure (Choice D) is not a goal in treating nephrotic syndrome and may even be contraindicated to prevent further kidney damage.
