Correct Answer: B

Rationale: The correct answer is B: sentinel event. A sentinel event is an unexpected occurrence involving death or serious physical or psychological harm to a patient. In this scenario, the accidental cutting of sutures leading to evisceration constitutes a serious harm to the patient, making it a sentinel event. This event requires immediate investigation, analysis, and implementation of preventive measures to ensure patient safety. A: Root cause refers to the underlying reason for a problem, not the event itself. C: Variation in performance is related to inconsistencies in processes, not a specific critical incident like evisceration. D: Causal factor is a contributing element to an event, but it does not capture the severity and significance of a sentinel event like evisceration.

Correct Answer: A

Rationale: The correct answer is A: Safe and effective care environment. The rationale is that assigning different nurses to care for a patient with shingles and a patient with HIV/AIDS is an example of maintaining infection control and preventing the spread of communicable diseases. This falls under the category of safe and effective care environment because it ensures proper isolation precautions are followed to protect both patients and healthcare workers. Summary: - Option A is correct because it relates to infection control and maintaining a safe care environment. - Option B, health promotion and maintenance, is not relevant to the scenario described. - Option C, psychosocial integrity, does not address the primary concern of preventing the spread of infection. - Option D, teaching/learning, is not the focus of the scenario, which is more about infection control and safety.

Correct Answer: B

Rationale: The correct answer is B because a "salvador" is typically a spiritual healer or medium in Hispanic culture who helps communicate with deceased family members. This aligns with the scenario of the patient seeking the services of a salvador to communicate with a family member who recently died. The other choices are incorrect because: A: Determining herbs for hot flashes is typically done by an herbalist or healthcare provider. C: Treating lower back pain usually involves medical professionals like doctors or physical therapists. D: Acupuncture for smoking cessation is typically provided by licensed acupuncturists or healthcare professionals, not a salvador.

Correct Answer: A

Rationale: The correct answer is A: "most insurance companies will pay for chiropractic treatment." Chiropractic care is a recognized form of treatment by most health insurance providers. Many insurance plans cover chiropractic services for conditions such as back pain. This is because chiropractic care is considered a cost-effective and evidence-based treatment option for musculoskeletal issues. Choice B is incorrect because chiropractors are licensed healthcare professionals in all states and many insurance plans do cover their services. Choice C is incorrect as chiropractic medicine is a well-established form of complementary and alternative medicine that is recognized by insurance companies. Choice D is incorrect because while chiropractic medicine does have preventive aspects, it is still commonly covered by insurance for treatment of various conditions.

Correct Answer: C

Rationale: The correct answer is C: National Nurses United. This is because National Nurses United is the largest union in the United States specifically representing registered nurses. They have a strong presence in advocating for nurses' rights and providing resources for unionizing efforts. A: American Nurses Association is a professional organization, not a union. B: United American Nurses was dissolved in 2009, so it is not the largest union. D: National Labor Relations Board is a government agency overseeing labor relations, not a union representing nurses.
