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

Correct Answer: B

Rationale: The rectal method of taking temperature is considered the most accurate because it closely reflects core body temperature. This method is recommended for infants, young children, and critically ill patients. Rectal temperature is not influenced by factors such as oral intake, environmental temperature, or mouth breathing. A: Oral temperature can be affected by drinking hot or cold fluids, smoking, or breathing through the mouth. C: Tympanic temperature can be influenced by earwax buildup, incorrect positioning, or ear infections. D: Axillary temperature is the least accurate method as it can be influenced by clothing, sweating, or improper placement of the thermometer.

Correct Answer: A

Rationale: Peristalsis is the correct answer because it refers to the wave-like muscular contractions that propel food through the digestive tract. These contractions help move food towards the stomach for further digestion. Mastication (chewing) is the mechanical breakdown of food in the mouth, not pushing food towards the stomach. Defecation is the process of eliminating waste from the body, not moving food towards the stomach. Absorption is the process by which nutrients are taken up by the body, not the muscular contractions that push food towards the stomach.

Correct Answer: C

Rationale: The correct answer is C because changing wet or soiled linens or incontinence briefs immediately is a crucial guideline for managing urinary incontinence. By promptly changing soiled linens and briefs, the nursing assistant helps maintain the resident's skin integrity, prevents skin breakdown, and promotes comfort and hygiene. This action also reduces the risk of infections and eliminates odors, contributing to the resident's overall well-being. Choice A is incorrect because privacy and confidentiality are essential in managing incontinence, and sharing this information with roommates is inappropriate. Choice B is incorrect because involving residents' families in managing incontinence should be done with the resident's consent and in a supportive, sensitive manner. Choice D is incorrect because proper hydration is important for overall health, and restricting fluids can lead to dehydration and other health complications.

Correct Answer: B

Rationale: The correct answer is B: Reporting signs of infection. Nursing assistants are not licensed to prescribe medications (A) or drain fluids (C). Administering medications (D) is typically done by licensed nurses. Reporting signs of infection is crucial in eczema management to prevent complications. Nursing assistants play a key role in observing and reporting any changes in the patient's condition to the healthcare team for proper treatment.

Correct Answer: B

Rationale: The correct answer is B: Respiration. Respiration refers to the process of breathing in and out, involving the exchange of oxygen and carbon dioxide in the lungs. Inspiration (A) specifically refers to the act of breathing in, while Expiration (C) refers to breathing out. Expansion (D) does not accurately describe the process of breathing and is therefore incorrect. In summary, Respiration encompasses both inspiration and expiration, making it the correct choice in this context.
