Correct Answer: B

Rationale: It is recommended that a child should visit the dentist within the next few months after turning two years old. This allows for early dental check-ups to monitor oral health, detect any issues early on, and establish a good oral hygiene routine. Choice A ('Before starting school') is not as specific and may delay the child's first dental visit. Choice C ('When the first deciduous teeth are lost') is too late for the first dental visit, as preventive care should start earlier. Choice D ('At the next dental visit of a family member') is not ideal as the child's dental needs should be addressed independently of family members' visits.

Correct Answer: D

Rationale: The Resiliency model of family stress, adjustment, and adaptation focuses on identifying the elements of risks and protective factors that help families achieve positive outcomes. In this scenario, the nurse recognizing homelessness as a risk aligns with the resiliency model, which emphasizes how families cope and adapt in the face of stressors. Duvall's theory primarily focuses on family life cycle stages, Friedman's theory emphasizes the roles and functions within a family structure, and Von Bertalanffy's theory looks at families as complex systems rather than specifically addressing resilience in the face of stressors.

Correct Answer: B

Rationale: The correct answer is B: Long-lasting active immunity is conferred. Tetanus toxoid injection works by stimulating the child's body to produce its antibodies, providing long-lasting active immunity. Choice A is incorrect because passive immunity is not conferred for life; it is temporary and involves receiving antibodies rather than producing them internally. Choice C is incorrect as the immunity conferred by the tetanus toxoid injection is not lifelong natural immunity but rather active immunity stimulated by the body's immune response. Choice D is also incorrect since passive natural immunity is not conferred by the tetanus toxoid injection, and it is not temporary.

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.
