Why is disposable equipment used in healthcare facilities?

Correct Answer: B

Rationale: The correct answer is B: Disposable equipment prevents the spread of microorganisms. This is because disposable items are single-use and reduce the risk of cross-contamination between patients, ultimately promoting infection control. Other choices are incorrect because: A) Cost-effectiveness is not the primary reason for using disposable equipment; C) Convenience for nursing assistants is not the main purpose; D) Safety is a consideration, but the primary benefit is in preventing the spread of microorganisms.

Correct Answer: B

Rationale: The rectal method is considered the most accurate for taking temperature because it reflects core body temperature most closely. This method provides a direct measurement from a highly vascular area near the body's core. Oral temperature can be influenced by drinking hot or cold liquids, while the tympanic method may be affected by factors like earwax buildup. Axillary temperature is typically lower than core body temperature due to external factors. Therefore, the rectal method is the most reliable for accurate temperature measurement.

Correct Answer: C

Rationale: The correct answer is C: Whole. According to MyPlate, half of the grains consumed should be whole grains for better nutritional value, such as fiber, vitamins, and minerals. Whole grains are less processed and retain more nutrients compared to refined grains (choices A and B). Flour (choice D) is an ingredient used to make various grain products and is not a specific recommendation for consumption. Therefore, choosing whole grains aligns with MyPlate's guidelines for a balanced and healthy diet.

Correct Answer: A

Rationale: Peristalsis is the coordinated muscular contractions that push food through the digestive system towards the stomach. It helps in the movement of food along the gastrointestinal tract. Mastication is the chewing of food, not pushing it towards the stomach. Defecation is the elimination of waste from the body, not pushing food towards the stomach. Absorption is the process of nutrients being taken up by the body, not related to pushing food towards the stomach.

Correct Answer: C

Rationale: The correct answer is C. The guideline for dealing with urinary incontinence is to change wet or soiled linens or incontinence briefs immediately to maintain skin integrity, prevent infections, and promote comfort. This helps in avoiding skin breakdown and potential complications related to prolonged exposure to moisture. Choice A is incorrect because sharing residents' incontinence status with roommates is a breach of privacy and confidentiality. Choice B is incorrect as it is not the role of the nursing assistant to disclose residents' incontinence episodes to their families without proper consent. Choice D is incorrect as withholding fluids can lead to dehydration and other health issues, which is not a recommended approach for managing urinary incontinence.
