Which of the following is an example of a prosthesis?

Correct Answer: D

Rationale: The correct answer is D. A prosthesis is an artificial body part designed to replace a missing limb. In this case, an artificial arm serves as a replacement for a lost arm. It is a functional and anatomically designed device that helps restore lost function. A) An assistive device for dressing (Choice A) does not involve replacing a missing limb and is not considered a prosthesis. B) Handrolls to prevent finger curling (Choice B) are not artificial limbs and do not replace a missing limb. C) Special shoes for flat feet (Choice C) are not artificial limbs and do not replace a missing limb.

Correct Answer: B

Rationale: The correct answer is B: Nonspecific immunity. Nonspecific immunity is the first line of defense against invading pathogens and does not target specific pathogens. It includes physical barriers like skin, mucous membranes, and chemical barriers like stomach acid and enzymes. Specific immunity (choice A) refers to the immune response targeted against specific pathogens. Active immunity (choice C) is immunity acquired through exposure to a pathogen or vaccine, leading to the production of antibodies. Passive immunity (choice D) is acquired through transfer of antibodies from another individual, providing immediate but temporary protection. Nonspecific immunity is the initial defense mechanism that protects the body from a wide range of pathogens before specific immunity is activated.

Correct Answer: A

Rationale: The correct answer is A. A nursing assistant should not get the unit or electrodes wet when caring for a resident with a telemetry pack to prevent damage to the equipment and ensure accurate monitoring of the resident's heart activity. Wet electrodes can interfere with the transmission of signals and lead to inaccurate readings. It is important to maintain the integrity of the equipment to provide proper care for the resident. Choices B, C, and D are incorrect. Choice B is incorrect because monitoring vital signs is an essential part of caring for a resident with a telemetry pack. Choice C is incorrect because cracked skin is not normal and should be reported to prevent skin irritation or infection. Choice D is incorrect because the electrodes should be securely attached to the resident's chest to ensure accurate readings, not hanging loosely.

Correct Answer: C

Rationale: The correct answer is C: 75 hours. This is because the Omnibus Budget Reconciliation Act (OBRA) of 1987 mandates a minimum of 75 hours of training for nursing assistants in federally regulated nursing homes. This requirement ensures that nursing assistants receive adequate training to provide quality care to residents. Choice A (30 hours) is incorrect as it does not meet the minimum training hours required by OBRA. Choice B (50 hours) is also incorrect as it falls short of the 75-hour minimum. Choice D (100 hours) is incorrect as it exceeds the minimum requirement set by OBRA. Thus, the correct answer is C as it aligns with the specific training hours mandated by OBRA for nursing assistants.

Correct Answer: B

Rationale: The correct answer is B: F-tags. In healthcare facilities, surveyors use F-tags to cite regulatory deficiencies. The letter "F" is associated with federal regulations, making F-tags the appropriate term. A: S-tags, C: I-tags, and D: P-tags are not commonly used terms in healthcare surveys. S-tags and I-tags do not align with the typical letter designation for federal regulations, while P-tags are not a recognized term in healthcare regulatory surveys.
