All of the following statements regarding pulse oximetry are true EXCEPT

Correct Answer: C

Rationale: Rationale: Choice C is incorrect because pulse oximetry provides a spot-check measurement of oxygen saturation, not continuous monitoring. A: Surrounding light can interfere with accuracy due to the device's sensitivity. B: Dysfunctional hemoglobin can affect readings. D: The technology relies on light absorption differences to measure oxygen levels accurately.

Correct Answer: D

Rationale: The correct answer is D: "Decreased pulse pressure." Airway compromise typically leads to increased pulse pressure due to increased sympathetic activity. A: "Change in voice" can indicate vocal cord dysfunction. B: "Stridor" is a high-pitched sound during inspiration, indicating upper airway obstruction. C: "Tachypnea" is rapid breathing, a compensatory mechanism in response to airway compromise.

Correct Answer: A

Rationale: The correct answer is A because holding oneself accountable involves taking responsibility for one's actions, including admitting mistakes and apologizing for them. This demonstrates honesty, integrity, and a willingness to learn and improve. Choices B, C, and D are incorrect because they do not directly address the concept of accountability. Speaking positively, working with diverse backgrounds, and caring about others are important qualities, but they do not specifically relate to the act of holding oneself accountable.

Correct Answer: C

Rationale: The correct answer is C because negligence refers to the failure to provide reasonable care that results in unintended harm or injury to a person. This involves a breach of duty of care leading to harm. Choice A and B refer to physical contact without permission, which is not directly related to negligence. Choice D is about emotional harm rather than negligence involving a failure to provide proper care.

Correct Answer: B

Rationale: The correct answer is B because accurate documentation is crucial for providing a clear, comprehensive, and current record of a resident's health status and care. This is vital for ensuring continuity of care, effective communication among healthcare team members, and tracking changes in the resident's condition over time. Choice A is incorrect as accurate documentation serves a broader purpose beyond just avoiding trouble. Choice C is incorrect as family members typically review medical charts infrequently and not as the primary reason for accurate documentation. Choice D is incorrect as the NA does not diagnose residents but rather documents observations and care provided.
