Which method of taking temperature is considered to be the most accurate?

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: 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.

Correct Answer: B

Rationale: The correct answer is B because reporting signs of infection is within the scope of a nursing assistant's responsibility for eczema. Nursing assistants are not qualified to prescribe medications (A), perform medical procedures like draining fluid (C), or administer medications (D). Recognizing signs of infection early helps prevent complications. Reporting to a nurse or healthcare provider ensures proper treatment and management of eczema.

Correct Answer: B

Rationale: The correct answer is B: Respiration. Respiration refers to the overall process of gas exchange in the body, including breathing in (inspiration) and breathing out (expiration). Inspiration (choice A) specifically refers to the act of inhaling air into the lungs. Expiration (choice C) refers to the act of exhaling air out of the lungs. Expansion (choice D) does not accurately describe the process of breathing in and out. Overall, respiration encompasses both inspiration and expiration, making it the correct choice in this context.
