Correct Answer: C

Rationale: A full-thickness (third-degree) burn involves the destruction of all layers of skin, including the epidermis, dermis, and extending into the subcutaneous tissue. This type of burn results in significant tissue damage and can appear pale, charred, or leathery. Choice A is incorrect as erythema and pain are more characteristic of superficial burns. Choice B describes a partial-thickness burn where the skin shows erythema followed by blister formation, involving the epidermis and part of the dermis. Choice D is incorrect as it describes a deeper type of injury involving structures beyond the skin layers, such as muscle, fascia, and bone, which is not specific to a full-thickness burn.

Correct Answer: C

Rationale: The priority nursing action after corrective surgery for hypertrophic pyloric stenosis (HPS) is to assess the IV site for infiltration. This is crucial as it ensures proper fluid administration and prevents complications such as phlebitis or infiltration-related tissue damage. Applying restraints (Choice A) would not be appropriate in this situation as it is not related to the immediate post-operative care of an infant with an IV infusion. Administering a mild sedative (Choice B) is not indicated as the primary concern post-surgery is monitoring the IV site and the infant's response to the surgery. Attaching the nasogastric tube to wall suction (Choice D) is not the priority at this time, as assessing the IV site takes precedence to prevent potential complications.

Correct Answer: C

Rationale: In small children, altered mental status can manifest as a lack of attention to the presence of unfamiliar individuals, such as the EMT-B. This lack of engagement may indicate confusion, disorientation, or impaired cognitive function. Choices A, B, and D are incorrect as recognizing parents, exhibiting fear, or maintaining consistent eye contact do not necessarily indicate altered mental status. Recognizing parents is a normal response, fear can be a typical reaction to unfamiliar situations, and making eye contact may be a sign of curiosity or comfort rather than a reflection of mental status.

Correct Answer: C

Rationale: A spiral fracture is a type of fracture often associated with twisting injuries and can raise suspicion of child abuse. This type of fracture is caused by a twisting force applied to a bone. Plastic deformity is not typically associated with fractures but refers to the ability of a material to change shape and retain that shape. A buckle fracture, also known as a torus fracture, is an incomplete break in a bone commonly seen in children. A greenstick fracture is an incomplete fracture where the bone is bent and partially broken, more commonly seen in children due to their bone flexibility.

Correct Answer: A

Rationale: The correct first intervention when managing a child with diabetic ketoacidosis is to begin intravenous saline solution to address dehydration and restore electrolyte balance. Rehydration is essential to improve perfusion and correct electrolyte imbalances. Administering insulin without addressing dehydration can potentially lead to further complications. Placing the child on a cardiac monitor or pulse oximetry monitor is important but not the initial priority in managing DKA.
