Which of the following statements is true of linen?

Correct Answer: D

Rationale: The correct answer is D. Dirty linen should be removed by rolling it away from the nursing assistant to prevent the spread of contaminants. Rolling helps contain any potential pathogens within the linen. Choice A is incorrect as linen should be carried away from the body to prevent contamination. Choice B is incorrect as shaking can spread germs. Choice C is incorrect as linen should not be transferred between rooms to prevent cross-contamination.

Correct Answer: B

Rationale: The correct answer is B: 60 to 100 beats per minute. This range is considered normal for adults because it reflects a healthy heart rate that can vary based on factors like age, fitness level, and overall health. A pulse rate below 60 may indicate bradycardia, while a rate above 100 may indicate tachycardia. Choices A, C, and D are incorrect because they fall outside the typical normal pulse rate range for adults, which can lead to potential health concerns.

Correct Answer: D

Rationale: The correct answer is D: Vegan diet. A vegan diet consists of only plant-based foods, excluding all animal products. This includes fruits, vegetables, grains, nuts, and seeds. The term "vegan" specifically denotes the exclusion of all animal-derived ingredients. Explanation: A: Lacto-ovo vegetarian diet includes dairy and eggs along with plant-based foods. B: Lacto-vegetarian diet includes dairy products along with plant-based foods. C: Ovo-vegetarian diet includes eggs along with plant-based foods. In summary, the vegan diet is the only option that exclusively includes plant-based foods without any animal products.

Correct Answer: D

Rationale: The correct answer is D: Heartburn. GERD is characterized by the backflow of stomach acid into the esophagus, leading to a burning sensation in the chest known as heartburn. This symptom is a hallmark of GERD, caused by the weakening of the lower esophageal sphincter. A: Diarrhea is not a common symptom of GERD. B: Lactose intolerance is a separate condition related to the inability to digest lactose, not directly associated with GERD. C: Constipation is also not a typical symptom of GERD, as it primarily involves acid reflux and heartburn. Therefore, the most appropriate choice is D as it aligns with the classic presentation of GERD.

Correct Answer: D

Rationale: The correct answer is D: Ketones. When the body burns fat for energy in the absence of enough insulin, ketones are produced and can be detected in the urine of individuals with diabetes. Ketones are acidic chemicals that can build up in the blood and urine, leading to a condition called diabetic ketoacidosis. Reagents (A) are substances used in chemical reactions, not produced in the body. Glucose (B) is typically found in the urine of individuals with uncontrolled diabetes but is not directly related to fat burning. Insulin (C) is a hormone that helps regulate blood sugar levels and is not a byproduct of fat metabolism.
