Correct Answer: B

Rationale: The correct first action for the LPN to take when a desired outcome is not achieved is to note which actions were not implemented. This step helps in identifying gaps in the plan of care and reasons for not achieving the desired outcome. Establishing a new nursing diagnosis (Choice A) is not the initial step when evaluating the plan of care. Adding additional nursing orders (Choice C) may not address the root cause of the unachieved outcome. Collaborating with the healthcare provider (Choice D) should come after identifying the gaps in the plan and reasons for the outcome not being met.

Correct Answer: A

Rationale: Before starting an intensive exercise program, it is crucial for the client to have a complete physical examination. This examination ensures that the client is physically fit to engage in such activities and helps in identifying any underlying health issues that could be exacerbated by the exercise regimen. Choice B is incorrect because it focuses on stress levels related to eating habits rather than the importance of a physical examination for safety. Choice C is incorrect as exercise and stress management classes can complement each other rather than being mutually exclusive. Choice D is incorrect as monitoring weight loss, while important, is not as critical as ensuring the client's physical readiness for the exercise program.

Correct Answer: B

Rationale: In a client with chronic kidney disease, elevated serum potassium levels (hyperkalemia) are the most concerning finding. Hyperkalemia can lead to life-threatening cardiac dysrhythmias. Monitoring and managing serum potassium levels are crucial in patients with kidney disease to prevent severe complications. While elevated creatinine (Choice A) and BUN (Choice C) are indicative of impaired kidney function, hyperkalemia poses a more immediate threat to the client's health. Hemoglobin levels (Choice D) can be affected by chronic kidney disease but are not as acutely dangerous as severe hyperkalemia.

Correct Answer: A

Rationale: The correct answer is A: A mole with an asymmetrical appearance. Asymmetry is a key characteristic of potential skin malignancy. An asymmetrical mole does not have a uniform shape when divided in half. This irregularity raises suspicion for skin cancer. Choices B, C, and D are incorrect. A mole with a regular border (B) is more likely to be benign. A mole that is the same color throughout (C) is also a feature commonly seen in benign moles. Additionally, a mole smaller than 6mm in diameter (D) is not necessarily indicative of malignancy, as some melanomas can be smaller or larger than this size.

Correct Answer: C

Rationale: The correct answer is C: Prothrombin time (PT). Prothrombin time is monitored to assess the therapeutic response to warfarin therapy. Warfarin works by inhibiting vitamin K-dependent clotting factors, which prolongs the PT. Monitoring PT helps determine if the client's blood is clotting within the desired therapeutic range. Choices A, B, and D are incorrect because bleeding time, coagulation time, and partial thromboplastin time are not specifically used to monitor the therapeutic response to warfarin. Bleeding time assesses platelet function, coagulation time is a general term and not a specific test, and partial thromboplastin time is more relevant in monitoring heparin therapy, not warfarin.
