Correct Answer: A

Rationale: The correct answer is A: Recent compliance with prescribed medications. In a client with chronic emphysema experiencing acute symptoms, it is crucial to assess medication compliance as it directly impacts the management of the condition and could contribute to the current presentation. Ensuring that the client has been taking their prescribed medications can provide vital information to guide further treatment. Choices B, C, and D, although important in a comprehensive assessment, are not as immediately crucial as assessing medication compliance in this emergency situation.

Correct Answer: A

Rationale: Administering an anticoagulant is the nurse's priority action in this situation. Given the client's history of DVT and the presentation of new onset shortness of breath and a productive cough, there is a concern for a pulmonary embolism, which is a life-threatening complication of DVT. Administering an anticoagulant promptly is crucial to prevent further clot formation and to manage the existing clot, reducing the risk of pulmonary embolism. While auscultating lung sounds and preparing for chest physiotherapy are important actions in respiratory assessment and management, the priority in this case is to address the potential complication of a pulmonary embolism by administering the anticoagulant. Notifying the healthcare provider can be done after initiating the immediate intervention of anticoagulant therapy.

Correct Answer: A

Rationale: The correct action the nurse should prioritize when a client is placed in skeletal traction for a fractured femur is to ensure that the weights are freely hanging. This is crucial to maintain proper alignment of the bone and prevent complications. Placing pillows under the client's knees (Choice B) is not a priority in skeletal traction. Adjusting the weights to alleviate discomfort (Choice C) should not be done without proper orders from the healthcare provider. Ensuring that the traction ropes are free of knots (Choice D) is important but ensuring the weights hang freely is the priority to maintain traction effectiveness.

Correct Answer: D

Rationale: The correct answer is D: Potassium. Spironolactone is a potassium-sparing diuretic, which can lead to hyperkalemia. Monitoring potassium levels is crucial to prevent complications like cardiac arrhythmias. Choices A, B, and C are incorrect because sodium, calcium, and magnesium levels are not directly affected by spironolactone use for managing ascites in cirrhosis.

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.
