Correct Answer: C

Rationale: Correct Answer: C - Administer IV fluids Rationale: 1. Assess patient's fluid status and hydration level. 2. IV fluids help maintain adequate hydration during hemodialysis. 3. Prevents hypotension and ensures stable blood pressure during the procedure. 4. Improves overall hemodialysis efficiency and patient safety. Summary: A: Checking patency is important, but not the primary intervention for hemodialysis. B: Monitoring for bleeding is crucial but not specific to AVF assessment. D: Applying an airtight dressing is not necessary for AVF assessment.

Correct Answer: D

Rationale: The correct answer is D because a functional assessment specifically evaluates an older adult's ability to manage day-to-day activities, such as personal care, meal preparation, and mobility. This assessment helps identify any difficulties the individual may have in performing these essential tasks, which can then inform appropriate interventions or support services. Choices A, B, and C are incorrect because they do not align with the primary focus of a functional assessment, which is to evaluate an individual's functional abilities and independence in daily living tasks, particularly in the context of aging or disability.

Correct Answer: C

Rationale: The correct answer is C: Place the client in a supine position. This is the first action because it helps prevent further injury to the spinal cord by maintaining alignment. Immobilizing the spine (choice A) is important but should come after placing the client in a supine position. Assessing the client's airway (choice B) is crucial but not the first action in a spinal cord injury. Encouraging deep breathing (choice D) is not appropriate as the priority is to stabilize the spine. In summary, placing the client in a supine position is the initial step to prevent worsening of the spinal cord injury, while the other choices are important but secondary actions.

Correct Answer: C

Rationale: The correct answer is C: Shortness of breath and chest pain. This is most concerning because it could indicate a pulmonary embolism, a serious complication of DVT where a blood clot travels to the lungs. Shortness of breath and chest pain are signs of compromised respiratory and cardiac function. A: Pain and swelling in the leg are common symptoms of DVT but not as concerning as symptoms of a pulmonary embolism. B: Redness and warmth around the affected area are typical signs of inflammation associated with DVT but do not indicate a life-threatening complication like a pulmonary embolism. D: Pale skin and decreased pulse in the affected leg could be signs of compromised circulation due to DVT, but they are not as immediately life-threatening as symptoms of a pulmonary embolism.

Correct Answer: A

Rationale: The correct answer is A because tolerance is a physiological phenomenon where the body adapts to a drug, requiring higher doses for the same effect. This is a common occurrence with opioids in chronic pain management. Choice B is incorrect as it refers to drug-seeking behavior, not tolerance. Choice C is incorrect because addiction and physical dependence are different concepts. Choice D is incorrect as it relates to a specific scenario of substance abuse alongside chronic pain, not the mechanism behind the need for increased opioid doses in chronic pain management.
