Infection prevention is

Correct Answer: B

Rationale: The correct answer is C: A set of methods used to prevent the spread of disease. Infection prevention involves implementing strategies to reduce the risk of infections spreading among individuals or within a community. This includes practices such as hand hygiene, proper sanitation, use of personal protective equipment, and vaccination. The other choices are incorrect because A does not fully encompass the comprehensive approach of infection prevention, and D is more related to the concept of a clean object rather than preventive measures against disease transmission.

Correct Answer: A

Rationale: The correct answer is A because documenting the incident is crucial for legal and healthcare purposes, ensuring accurate record-keeping and accountability. Giving an opinion (B) is outside the scope of a nursing assistant's role and can be subjective. Expressing personal emotions to the resident (C) can be unprofessional and may cause unnecessary stress. Prescribing medication (D) is beyond the nursing assistant's scope of practice and should be done by a licensed healthcare provider. Thus, option A is the most appropriate choice in this scenario.

Correct Answer: B

Rationale: The correct answer is B because a nursing assistant can use a tape measure to measure the height of a resident who cannot get out of bed. They can gently extend the tape measure from the top of the resident's head to the bottom of their feet while ensuring the tape measure is straight and level. This method provides an accurate measurement of the resident's height. Choice A is incorrect because a scale is used to measure weight, not height. Choice C is incorrect as estimating height visually is not an accurate method. Choice D is incorrect because there are ways, such as using a tape measure, to measure the height of a resident who cannot get out of bed.

Correct Answer: D

Rationale: The correct answer is D because bedbound residents are at high risk for pressure injuries due to prolonged pressure on their skin. Repositioning every three hours helps redistribute pressure, promoting circulation and preventing skin breakdown. Choice A is incorrect because residents may still need assistance with positioning. Choice B is incorrect as constant pressure can lead to pressure injuries. Choice C is incorrect as checking the skin each time a resident is repositioned may not be necessary for every resident.

Correct Answer: B

Rationale: The correct answer is B: At least twice a day. Providing mouth care at least twice a day is essential for maintaining good oral hygiene in residents. Brushing teeth and cleaning the mouth regularly helps prevent dental issues, infections, and bad breath. By doing it twice a day, it ensures that bacteria and plaque are effectively removed, reducing the risk of oral health problems. A: Once a day may not be sufficient to adequately clean the mouth and maintain oral health for residents. C: Only when the resident requests it is not a recommended approach, as residents may not always be aware of their oral care needs. D: Every other day is not frequent enough to prevent oral health issues and maintain good hygiene.
