The immediate cause of bed sore is:

Correct Answer: B

Rationale: The correct answer is B: Sustained pressure. Bed sores, also known as pressure ulcers, develop due to prolonged pressure on the skin that hinders blood flow, leading to tissue damage. The constant pressure restricts oxygen and nutrients to the affected area, causing the skin and underlying tissues to break down. This can happen when a person remains in one position for an extended period, such as when lying in bed or sitting in a wheelchair. Infection (choice A) can occur as a complication of bed sores, but it is not the immediate cause. Choices C and D are incomplete and do not provide a logical explanation for the development of bed sores.

Correct Answer: A

Rationale: The correct answer is A: Caused by trauma. A wheel formed on the arm is a common manifestation of dermatographia, a condition where pressure on the skin causes it to become raised and red. Trauma, such as scratching or rubbing the skin, triggers this reaction in individuals with dermatographia. The other choices are incorrect because dermatographia is not caused by a reaction to any external substance or allergen (choice B), and the options C and D are left blank as they do not provide any relevant information related to the formation of a wheel on the arm.

Correct Answer: A

Rationale: Step 1: Breathing into a brown bag helps rebalance oxygen and carbon dioxide levels in the blood. Step 2: Excessive breathing lowers carbon dioxide levels causing symptoms like dizziness, tingling. Step 3: Breathing into a brown bag helps retain carbon dioxide, reducing symptoms quickly. Step 4: Performing Coach breathing, a breathing technique, would not address the underlying issue of low carbon dioxide levels. Step 5: Choice C and D are not provided, so irrelevant to the question.

Correct Answer: B

Rationale: Step-by-step rationale: 1. Acute illnesses typically have a sudden onset and run a short course. 2. Remissions and exacerbations are characteristic of chronic illnesses, not acute ones. 3. Therefore, the statement that an acute illness is characterized by remissions and exacerbations is false. Summary: A is incorrect because acute illnesses do not have remissions and exacerbations. Choice B is correct as it aligns with the definition of acute illnesses. Choices C and D are invalid as they are blank.

Correct Answer: B

Rationale: The correct answer is B because the acronym DABDA stands for Denial, Anger, Bargaining, Depression, Acceptance, which are the stages of grief proposed by Elisabeth Kübler-Ross. These stages do not happen in a single cycle but can repeat in a non-linear way as individuals navigate through the grieving process. Choice A is incorrect because the stages do not occur just once. Choices C and D are incorrect because they do not provide any relevant information related to the stages of grief.
