A 7-year-old child accidentally touches a hot stove, resulting in redness on his palm without blisters.
What type of burn is this?
First-degree burn.
Second-degree burn.
Third-degree burn.
Full-thickness burn.
The Correct Answer is A
Choice A rationale
A first-degree burn involves only the epidermis, the outermost layer of the skin. It is characterized by redness (erythema), pain, and dryness, without the formation of blisters. The superficial damage affects the outer layer of epithelial cells, causing vasodilation and inflammation, leading to the observed redness and discomfort.
Choice B rationale
A second-degree burn involves the epidermis and a portion of the dermis, the layer beneath the epidermis. These burns are characterized by blisters, significant pain, redness, and swelling. The damage extends deeper into the skin, affecting nerve endings and blood vessels, leading to fluid leakage and blister formation.
Choice C rationale
A third-degree burn involves the destruction of the epidermis and the entire dermis, potentially extending into the subcutaneous tissue. These burns appear white or charred, are often painless initially due to nerve damage, and lack blisters. The full thickness destruction of skin layers impairs sensation and requires significant medical intervention, often including skin grafting.
Choice D rationale
Full-thickness burn is another term for a third-degree burn, indicating that all layers of the skin have been destroyed. This type of burn extends through the epidermis and dermis and may involve underlying subcutaneous tissue, muscle, or bone. The appearance is typically dry, leathery, and may be white, charred, or waxy.

Correct Answer is ["A","C","D"]
Explanation
Choice A rationale
Ensuring suction equipment is readily available is crucial for a child with a history of seizures because they are at an increased risk of aspiration during or immediately following a seizure. Suctioning helps to clear the airway of saliva, vomitus, or other secretions, preventing respiratory complications.
Choice C rationale
Padding the side rails of the child's bed provides a protective barrier against injury during a seizure. Tonic-clonic seizures involve sudden, uncontrolled muscle contractions that can cause the child to hit the side rails, potentially leading to bruising or more serious injuries. Padding helps to cushion these impacts.
Choice D rationale
Educating parents on how to administer rectal diazepam for breakthrough seizures at home empowers them to manage prolonged or clustered seizures promptly. Rectal diazepam is a benzodiazepine medication that can effectively stop a seizure, reducing the risk of status epilepticus, a medical emergency.
Correct Answer is B
Explanation
Choice B rationale
Regular soda contains high amounts of simple sugars, which will rapidly increase blood glucose levels. For a child with type 1 diabetes experiencing hypoglycemia (low blood sugar), a quick-acting source of glucose like juice or glucose tablets is preferred over regular soda due to its predictable and faster absorption.
