During a well-child checkup, a mother tells Nurse Rio about a recent situation in which her child needed to be disciplined by her husband. The child was slapped in the face for not getting her husband breakfast on Saturday, despite being told on Thursday never to prepare food for him. Nurse Rio analyzes the family system and concludes it is dysfunctional. All of the following factors contribute to this dysfunction except:

Correct Answer: C

Rationale: In a dysfunctional family system, conflictual relationships, inconsistent communication patterns, and the use of violence to establish control are factors contributing to dysfunction. However, rigid, authoritarian roles, though also dysfunctional, are not directly linked to the use of violence for control.

Correct Answer: D

Rationale: The school nurse's priority intervention in this situation is to report suspicion of abuse to the proper authorities. Given the pattern of unexplained injuries and vague explanations provided by the child, it raises significant concerns for possible abuse. Reporting to the appropriate authorities is crucial to ensure the child's safety and well-being. Contacting the child's parents (Choice A) may not be appropriate if abuse is suspected, as it could potentially put the child at further risk. Merely encouraging the child to be honest (Choice B) does not address the immediate safety concerns. Questioning the teacher (Choice C) is not the appropriate initial action when abuse is suspected; reporting to authorities should take precedence.

Correct Answer: C

Rationale: The correct answer is C: genetically modified food. Canola plants with altered genomes to be herbicide-resistant are an example of genetically modified organisms (GMOs). Genetically modified foods have their genetic material modified for various purposes, such as enhancing resistance to pests, herbicides, or improving nutritional content. Choice A, 'pesticide-free food,' is incorrect because genetic modification does not necessarily make the food pesticide-free. Choice B, 'saturated fat food,' is incorrect as it does not relate to the genetic modification of the canola plant. Choice D, 'product that is pure,' is too vague and does not specifically address the genetic modification aspect of the canola plant.

Correct Answer: A

Rationale: The correct answer is A: live and can cause infection. In patients like the one described with a history of heart transplant and receiving long-term steroids, who are immunocompromised, live attenuated vaccines are contraindicated. Live vaccines contain weakened (attenuated) forms of the virus or bacteria, which can replicate and cause mild infections in healthy individuals but can lead to serious infections in immunocompromised individuals. Choices B, C, and D are incorrect because attenuated vaccines are not mutated, not inactive, and not pathogenic in healthy individuals, respectively.

Correct Answer: B

Rationale: Neutrophils are the first responders to bacterial infections. When there is a breach in the skin like in this scenario, neutrophils are quickly recruited to the site of injury to phagocytize and kill bacteria. Eosinophils are primarily involved in parasitic infections and allergic reactions, making choice A incorrect. Leukotrienes are lipid mediators involved in inflammation but are not cells, so choice C is incorrect. Monocytes are precursors to macrophages and play a role in immune response, but they are not the first cells to arrive at the site of a bacterial infection, making choice D incorrect.
