Correct Answer: A

Rationale: A pale foot with no pulse suggests a compromised blood supply, indicating a potential vascular emergency. The nurse's immediate priority is to notify the healthcare provider to address the situation promptly. Readjusting the traction, administering PRN medication, or waiting to reassess the foot later could lead to serious complications due to the compromised blood supply, making choices B, C, and D incorrect in this critical situation.

Correct Answer: A

Rationale: The correct answer is to evaluate the closest proximal pulse when assessing tissue perfusion post-above knee amputation (AKA). Checking the closest proximal pulse provides the best indication of tissue perfusion in the extremities after an AKA procedure. Observing the color and amount of wound drainage (Choice B) is important for wound care but does not directly assess tissue perfusion. Observing for swelling around the stump (Choice C) may indicate inflammation or fluid accumulation but is not the most direct way to assess tissue perfusion. Assessing the skin elasticity of the stump (Choice D) is more related to skin integrity and wound healing rather than tissue perfusion.

Correct Answer: C

Rationale: The correct answer is C. Administering prescribed corticosteroids to reduce inflammation is the priority action when a client with multiple sclerosis is admitted with an acute exacerbation. Corticosteroids help manage symptoms during exacerbations and reduce inflammation. Monitoring vital signs and assessing muscle strength are important aspects of care but not the priority during an acute exacerbation. Educating the client on managing fatigue and preventing relapses is essential but can be addressed after the acute exacerbation has been managed.

Correct Answer: B

Rationale: The correct action is to have a licensed practical nurse (LPN) assess the client for an apical-radial pulse deficit. This assessment can provide further information about the client's cardiovascular status and help determine if further intervention is necessary. Having the UAP recheck the pulse may delay appropriate assessment and intervention. Calling the healthcare provider for further instructions may not be necessary at this point unless the LPN assessment indicates a need for it. Immediately transferring the client to critical care without further assessment is not warranted based solely on the initial report of a weak pulse.

Correct Answer: D

Rationale: The correct answer is D, 'All of the above.' When developing educational materials for older clients with new antihypertensive medications, it is essential to include characteristics such as using pictures to illustrate complex ideas, providing a list with definitions of unfamiliar terms, and using common words with few syllables. These features help enhance understanding and medication adherence, especially for older adults who may have challenges with health literacy. Choices A, B, and C collectively address the need for simplicity, visual support, and clarification of terms in educational materials, making them crucial for effective patient education.
