Which of the following statements is true of chest tubes?

Correct Answer: B

Rationale: The correct answer is B because observing the amount and color of chest drainage is crucial to monitor the resident's condition and detect any complications. Changes in amount or color can indicate bleeding, infection, or other issues. This helps in assessing the effectiveness of the chest tube and determining the need for any interventions. A is incorrect because the drainage system should be kept below the level of the resident's chest to facilitate drainage. C is incorrect as tubing should never be kinked as it can obstruct the flow of drainage, leading to complications. D is incorrect as chest tubes can be placed in various locations, not just in the front of the body.

Correct Answer: B

Rationale: The correct answer is B: Civil law. Private law, also known as civil law, governs the relationships between individuals, including contracts, property, and personal injury cases. Criminal law (A) deals with offenses against the state. Contract law (C) is a subset of civil law focusing on agreements between parties. International law (D) regulates relationships between countries. Therefore, the correct answer is civil law as it specifically pertains to interactions between individuals.

Correct Answer: B

Rationale: The correct answer is B because stating Mrs. Lin Ho's respiratory rate of 23 breaths per minute is a factual, measurable, and observable piece of information. It is objective as it can be confirmed through direct observation or measurement. In contrast, choices A, C, and D involve subjective interpretations or feelings that cannot be independently verified. Choice A is based on a subjective assessment of Mrs. Lin Ho's back condition, choice C is about her desires, and choice D relates to her emotional state, all of which are subjective and influenced by personal perceptions or biases. Therefore, choice B stands out as the only option that provides concrete and verifiable information, making it the example of objective information in this scenario.

Correct Answer: A

Rationale: The correct answer is A because families and friends provide a link to the outside world for residents, helping them stay connected and maintain social relationships. This support is crucial for residents' emotional well-being. Choice B is incorrect as it focuses on staff members, not residents. Choice C is incorrect as physical therapy is typically provided by healthcare professionals, not friends and families. Choice D is incorrect as it suggests a negative impact on residents' communication, which is not supportive.

Correct Answer: B

Rationale: Step-by-step rationale for why choice B is correct: 1. Indirect contact involves transmission via contaminated objects. 2. Option B states that a person touches an object contaminated by an infected person. 3. This aligns with the definition of indirect contact transmission. 4. Touching contaminated objects can transfer pathogens to individuals. Summary: A, C, D are incorrect as they involve direct contact or specific body parts not mentioned in the definition of indirect contact transmission. Option B correctly identifies the mode of transmission involving contaminated objects, making it the correct answer.
