With whom should a nursing assistant use Standard Precautions?

Correct Answer: C

Rationale: Standard Precautions are designed to prevent the transmission of infectious agents in healthcare settings. Choice C is correct as it states that a nursing assistant should use Standard Precautions with every resident in their care, regardless of their known or suspected infectious status. This approach ensures consistent infection control practices and minimizes the risk of spreading infections. Choices A, B, and D are incorrect because Standard Precautions should not be based on self-reporting by residents or their requests; they should be applied universally to all residents to maintain a safe and healthy environment.

Correct Answer: A

Rationale: The correct answer is A because diabetic ketoacidosis occurs when there is an absolute or relative deficiency of insulin in the body. Without enough insulin, the body cannot use glucose for energy, leading to the breakdown of fats and the production of ketones, causing ketoacidosis. Choices B, C, and D are incorrect because having too little insulin (B) leads to diabetic ketoacidosis, not too much insulin. Eating too little food (C) may result in low blood sugar but not diabetic ketoacidosis. Too much exercise (D) can lower blood sugar levels but is not a direct cause of diabetic ketoacidosis.

Correct Answer: C

Rationale: The correct answer is C: Placement of meals. An overbed table is specifically designed to provide a convenient surface for patients to eat their meals while in bed. It helps to ensure a comfortable and accessible dining experience for patients who are unable to sit at a traditional table. Choices A, B, and D are incorrect because an overbed table is not intended for placement of dirty linens, bedpans, or urinals. These items should be placed elsewhere for hygiene and sanitation purposes.

Correct Answer: A

Rationale: The correct answer is A: Partial bath. For an elderly person with very dry skin, a partial bath is appropriate as it helps to prevent further drying of the skin by focusing on areas that need cleaning, while minimizing exposure to water which can exacerbate dryness. Other choices such as a shower or tub bath involve prolonged exposure to water and may strip the skin of its natural oils, worsening dryness. A complete bed bath is not necessary for someone with dry skin and can be physically taxing for the elderly individual.

Correct Answer: C

Rationale: The correct answer is C: Axilla. The axilla is the anatomical term for the armpit region. The axilla contains lymph nodes, blood vessels, and nerves that supply the upper limb. The other choices are incorrect: A tympanum refers to the eardrum, B rectum is part of the digestive system, and D temporal pertains to the side of the head.
