Why is disposable equipment used in healthcare facilities?

Correct Answer: B

Rationale: The correct answer is B because disposable equipment helps prevent the spread of microorganisms by eliminating the risk of contamination from previous uses. This is crucial in healthcare settings to maintain aseptic conditions and prevent infections. Choosing option A for cost-effectiveness may compromise patient safety. Option C is focused on convenience rather than infection control. Option D is too broad and doesn't specifically address the purpose of using disposable equipment in healthcare.

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: C

Rationale: The correct answer is C: Whole. According to MyPlate, half of the grains a person consumes should be whole grains for better nutrition and health benefits. Whole grains contain all parts of the grain kernel, including the bran, germ, and endosperm, providing more fiber, vitamins, and minerals compared to refined grains. Choosing whole grains over refined grains can help lower the risk of chronic diseases like heart disease and diabetes. Option A (White) and B (Refined) are incorrect as they do not offer the same nutritional benefits as whole grains. Option D (Flour) is too broad and does not specify whether it is whole grain flour or refined flour.

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.
