Which of the following is an example of a prosthesis?

Correct Answer: D

Rationale: The correct answer is D because a prosthesis is an artificial device that replaces a missing body part. In this case, an artificial arm replaces a lost arm. Choice A is incorrect as it refers to an assistive device for dressing, not a body part replacement. Choice B is incorrect as handrolls are not used to replace a missing body part. Choice C is incorrect as special shoes for flat feet do not replace a body part. In summary, only choice D aligns with the definition of a prosthesis by replacing a missing body part with an artificial device.

Correct Answer: B

Rationale: The correct answer is B: Nonspecific immunity. This type of immunity provides general protection against a wide range of pathogens and is the body's first line of defense. Nonspecific immunity includes physical barriers like skin, mucous membranes, and certain cells that engulf and destroy pathogens. Specific immunity (A) is tailored to a particular pathogen, while active immunity (C) is acquired through vaccination or exposure to a pathogen, and passive immunity (D) is temporary protection transferred from another source. Therefore, B is the correct choice as it best describes the general defense mechanism against invading bacteria or organisms.

Correct Answer: A

Rationale: Correct Answer: A. The NA should not get the unit or electrodes wet. Rationale: 1. Moisture can damage the telemetry equipment, affecting accurate monitoring. 2. Wet electrodes may cause skin irritation or burns to the resident. 3. Proper care includes keeping the equipment dry to ensure resident safety and accurate monitoring. Summary of Incorrect Choices: B. The NA should monitor vital signs to ensure the resident's safety. C. Reporting cracked skin is important as it may indicate skin irritation or infection. D. Ensuring that the electrodes hang loosely can lead to poor electrode contact and inaccurate readings.

Correct Answer: C

Rationale: The correct answer is C: 75 hours. This is the minimum number of hours of nursing assistant training required by the Omnibus Budget Reconciliation Act (OBRA). OBRA mandates that nursing assistants complete 75 hours of training, including 16 hours of supervised practical training. Choice A (30 hours) is too low, choice B (50 hours) does not meet the minimum requirement, and choice D (100 hours) exceeds the minimum training hours specified by OBRA. Therefore, choice C is the correct answer as it aligns with the specific training hours mandated by OBRA.

Correct Answer: B

Rationale: The correct answer is B: F-tags. In healthcare facilities, surveyors use F-tags to cite problems found during inspections. These tags are part of the regulatory guidelines set by the Centers for Medicare and Medicaid Services (CMS) to ensure compliance with health and safety standards. S-tags, I-tags, and P-tags do not specifically refer to the citations used by surveyors in healthcare facilities. Therefore, B is the correct choice as it directly relates to the tagging system used for identifying issues in healthcare settings.
