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: B

Rationale: The most appropriate time for a child to first visit the dentist is within the next few months after turning two years old. This visit allows the dentist to assess the child's oral health, provide guidance on proper oral hygiene practices, and establish a positive relationship with dental care. Choice A (Before starting school) is not as specific and timely as the recommended age of 2 years. Choice C (When the first deciduous teeth are lost) is not ideal as preventive dental visits should start earlier to establish good oral health habits. Choice D (At the next dental check-up for a family member) may delay the child's first dental visit, missing the opportunity for early preventive care and guidance.

Correct Answer: D

Rationale: Elevating the head of the bed is crucial in the care plan for an infant with RSV as it helps improve breathing by facilitating better airflow and drainage of secretions. This position can also enhance comfort and reduce respiratory distress. Providing small, frequent feedings (Choice A) is generally beneficial for infants but is not specific to managing RSV. Administering antibiotics (Choice B) is not indicated for RSV as it is caused by a virus, and antibiotics are ineffective against viral infections. Maintaining strict isolation (Choice C) is important to prevent the spread of contagious infections but is not a direct intervention for improving the infant's respiratory status in RSV.

Correct Answer: B

Rationale: The correct answer is B: 'Long-lasting active immunity is conferred.' Tetanus toxoid injection provides long-lasting active immunity by stimulating the body to produce its own antibodies. Choice A is incorrect because tetanus toxoid injection does not provide passive immunity. Choice C is incorrect because the immunity conferred by the vaccine is not natural but artificially induced. Choice D is incorrect as the immunity provided by the tetanus toxoid injection is active, not passive.

Correct Answer: C

Rationale: The priority nursing action after a corrective surgery for hypertrophic pyloric stenosis (HPS) is to assess the IV site for infiltration. This is crucial to ensure proper fluid administration and prevent complications such as extravasation or infiltration. Applying restraints (Choice A) is not indicated in this scenario and can compromise the infant's comfort and safety. Administering a mild sedative (Choice B) is not necessary and should only be done based on specific clinical indications. Attaching the nasogastric tube to wall suction (Choice D) may be important for certain conditions but is not the priority immediately post-surgery; assessing the IV site is more urgent to prevent potential complications related to IV therapy.
