Diabetic ketoacidosis may be caused by

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: 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.

Correct Answer: A

Rationale: Step-by-step rationale: 1. MyPlate recommends choosing low-fat or fat-free dairy for better health. 2. 1% fat dairy is lower in saturated fat compared to 2%, 3%, or 4% fat options. 3. Lower fat content aligns with dietary guidelines for reducing saturated fat intake. 4. Choosing 1% fat dairy helps in maintaining a healthy weight and heart health. Summary: A is correct as it aligns with MyPlate's recommendation for low-fat dairy. B, C, and D are incorrect as they contain higher fat content, which may contribute to higher saturated fat intake and potential health risks.

Correct Answer: C

Rationale: The correct answer is C: Organ. An organ is a group of tissues that work together to perform specific functions. The heart is made up of different types of tissues (muscle, nerve, connective) that work together to pump blood throughout the body. It is more complex than a single cell (A), a group of cells (tissue - B), or a system of organs working together (body system - D). The heart's structure and function clearly demonstrate its classification as an organ.
