Which of the following statements is true of linen?

Correct Answer: D

Rationale: The correct answer is D because rolling dirty linen away from the nursing assistant prevents contamination and exposure to pathogens. By rolling the linen, the nursing assistant minimizes the risk of spreading any dirt, bacteria, or other contaminants on their uniform or skin. This method ensures proper infection control practices. Explanation for why the other choices are incorrect: A: Linen should not be carried close to the nursing assistant's uniform to prevent contamination and cross-contamination. B: Shaking linen to remove wrinkles does not address the proper handling of dirty linen. C: Linen should not be taken from one resident's room to another to prevent the spread of infection and maintain hygiene standards.

Correct Answer: B

Rationale: The correct answer is B (60 to 100 beats per minute) as it reflects the typical range for adults. A (25 to 50 bpm) is too low for a healthy adult, C (0 to 50 bpm) includes unrealistic values, and D (50 to 75 bpm) is too narrow as it excludes the higher end of the normal range. A normal adult heart rate falls within the range of 60 to 100 beats per minute, which is important for efficient circulation and oxygen delivery throughout the body.

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 is because vegans do not consume any animal-derived products, including meat, dairy, eggs, and honey. The other choices, A, B, and C, all include some form of animal products in the diet. Lacto-ovo vegetarian diet (A) includes dairy and eggs, lacto-vegetarian diet (B) includes dairy but not eggs, and ovo-vegetarian diet (C) includes eggs but not dairy. Therefore, the vegan diet (D) is the only option that aligns with being entirely plant-based.

Correct Answer: D

Rationale: The correct answer is D: Heartburn. GERD commonly presents with heartburn due to the backflow of stomach acid into the esophagus. This symptom is a result of the weakening of the lower esophageal sphincter. Diarrhea (A), lactose intolerance (B), and constipation (C) are not typically associated with GERD. Diarrhea is more commonly linked to infections or certain food intolerances. Lactose intolerance causes symptoms like bloating and gas after consuming dairy, not specifically reflux. Constipation is more related to issues with bowel movements and not typically a symptom 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. People with diabetes may have ketones in their urine due to inadequate insulin levels. Reagents (A) are substances used in chemical reactions, not produced in the body. Glucose (B) is a sugar and is typically found in the blood, not urine in high amounts. Insulin (C) is a hormone that regulates blood sugar levels and is not typically found in urine.
