All of the following statements regarding pulse oximetry are true EXCEPT

Correct Answer: C

Rationale: Rationale: C is incorrect because pulse oximetry provides a spot-check measurement, not continuous. A is true as room light can interfere. B is true as dysfunctional hemoglobin can affect accuracy. D is true as pulse oximetry relies on differential light absorption. Therefore, the correct answer is C.

Correct Answer: D

Rationale: The correct answer is D, "Decreased pulse pressure," because it is not a typical sign or symptom of airway compromise. Airway compromise usually presents with changes in voice (A), stridor (B), and tachypnea (C) due to obstruction or narrowing of the airway. Decreased pulse pressure is more indicative of cardiovascular issues rather than airway compromise. In summary, choices A, B, and C are related to airway compromise symptoms, while choice D is not directly associated with it.

Correct Answer: A

Rationale: The correct answer is A: Admit mistakes and apologize for them. Holding oneself accountable involves taking responsibility for one's actions, acknowledging mistakes, and making amends. By admitting mistakes and apologizing, one demonstrates integrity and a commitment to learning and growth. Choices B, C, and D are incorrect because they do not directly address the key aspect of accountability, which is owning up to one's errors and taking appropriate actions to rectify them. Speaking positively, working with diverse backgrounds, and caring about others' problems are important traits, but they do not fully capture the essence of accountability.

Correct Answer: C

Rationale: The correct answer is C: Actions or the failure to act or give care to a person, resulting in unintended injury. Negligence refers to the failure to exercise reasonable care, resulting in harm to others. This definition aligns with the legal concept of negligence, where individuals are expected to act reasonably to prevent harm to others. Choices A and B are related to physical contact and do not encompass the broader concept of negligence. Choice D is about emotional harm, not unintentional injury, which is the key aspect of negligence. Therefore, choice C is the correct answer as it best captures the essence of negligence in terms of actions or inactions leading to unintended harm.

Correct Answer: B

Rationale: The correct answer is B because accurate documentation is crucial in providing a clear, detailed, and real-time record of a resident's status and care. This helps ensure continuity of care, enables healthcare professionals to make informed decisions, and promotes resident safety. In contrast, option A is incorrect as accurate documentation is not just about avoiding trouble, but rather ensuring quality care. Option C is incorrect because family members typically review medical charts for updates on their loved one's condition rather than as the primary reason for accurate documentation. Option D is incorrect because the NA does not diagnose residents but rather documents their care and status.
