Correct Answer: B

Rationale: Choosing option B, 'Buy a soda and hamburger to eat,' is the most appropriate action for an adolescent with type 1 diabetes experiencing an insulin reaction during a basketball game. In this situation, the individual is likely experiencing hypoglycemia, and consuming a soda provides a quick source of sugar to raise blood glucose levels rapidly. The hamburger can offer a more sustained release of energy due to its protein and fat content. Option A is incorrect because while contacting parents for help may be necessary in some situations, immediate action to address hypoglycemia is crucial. Option C is incorrect because administering insulin would further lower blood sugar levels, worsening the condition. Option D is incorrect as leaving the arena without addressing the hypoglycemia can lead to a worsening of symptoms and potentially dangerous outcomes.

Correct Answer: D

Rationale: The correct answer is D: 'It is a connection between the pulmonary artery and the aorta.' Patent ductus arteriosus (PDA) is an abnormal connection between the pulmonary artery and the aorta, which normally closes after birth. Choices A, B, and C describe different cardiac conditions and do not accurately define PDA. Choice A is incorrect because PDA does not involve the diameter of the aorta being enlarged. Choice B is incorrect because PDA does not involve the wall between the right and left ventricles being open. Choice C is incorrect because PDA is not a narrowing of the entrance to the pulmonary artery.

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: A

Rationale: In this scenario, the most appropriate intervention to prevent further injury is to raise the bed's side rails when a caregiver is not present. This measure helps in preventing falls without the need for constant supervision. Choice B is not practical as continuous caregiver presence may not always be feasible. Choice C is unsafe as loose restraints can pose a strangulation risk. Choice D does not address the need for intervention when a caregiver is absent, potentially leading to an increased risk of falls.

Correct Answer: B

Rationale: The correct answer is B. While special dietary needs may be important, they are not typically a primary concern for a 1-month-old with Down syndrome compared to monitoring for congenital issues. Getting cervical radiographs, an echocardiogram, and monitoring for respiratory infections are more crucial in the early care of a child with Down syndrome. Cervical radiographs help in assessing for atlantoaxial instability, an echocardiogram is important for detecting congenital heart defects common in Down syndrome, and monitoring for respiratory infections is vital due to the increased risk in these children.
