Correct Answer: C

Rationale: In this scenario, the correct answer is C. Any vital signs outside the expected range in an infant should be documented and reported, as they may indicate a developing condition that requires prompt attention. Choice A is incorrect because slow respirations in infants should not be dismissed without assessment and documentation. Choice B is incorrect because a drop in respiratory rate in this case was significant and should have been documented. Choice D is incorrect because even though infants have underdeveloped respiratory tracts, any abnormal respiratory rate should be taken seriously and documented for monitoring and intervention if necessary.

Correct Answer: B

Rationale: When an adolescent with type 1 diabetes experiences an insulin reaction, it is essential to quickly raise their blood sugar levels. Buying a soda and a hamburger to eat is the best choice in this situation as it provides a fast-acting source of sugar to counteract hypoglycemia. Calling parents immediately may cause a delay in receiving appropriate treatment. Administering insulin would further lower blood sugar levels, worsening the situation. Leaving the arena and resting would not address the immediate need to raise blood sugar levels.

Correct Answer: D

Rationale: For a child with muscular dystrophy who fell out of bed, it is important to prevent further injuries. Using bed side rails when a caregiver is not present can help provide a safety measure and prevent falls. While continuous caregiver presence (choice B) may be ideal, it may not always be feasible. Recommending raising the bed's side rails throughout the day and night (choice A) may limit the child's mobility unnecessarily. Encouraging the use of a loose restraint (choice C) can be dangerous and may increase the risk of injury in case of a fall.

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: 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.
