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: A

Rationale: The initial action the nurse should take after discovering a client's eviscerated wound is to cover the incision with a moist sterile dressing. This step is crucial to protect the exposed tissue, prevent infection, and create a conducive environment for healing. While notifying the surgeon is important, addressing the wound immediately takes precedence. Assessing vital signs is essential but should follow the immediate intervention of covering the wound. Placing the client in a supine position with knees bent is not the priority in managing an eviscerated wound; the first step is to cover the wound to protect the exposed tissue.

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.

Correct Answer: D

Rationale: In acetaminophen poisoning, liver damage is a significant concern due to the drug's metabolism in the liver. Monitoring liver enzymes such as AST and ALT is crucial as they indicate liver function and damage. Prothrombin time (PT) and partial thromboplastin time (PTT) (Choice A) are coagulation studies and are not the priority in acetaminophen poisoning. Red blood cell and white blood cell counts (Choice B) are not directly related to acetaminophen poisoning. Blood urea nitrogen and creatinine levels (Choice C) assess kidney function, but liver enzymes are more specific for evaluating liver damage in acetaminophen poisoning.

Correct Answer: B

Rationale: The correct answer is B because the nursing diagnosis of Impaired physical mobility is appropriate for a patient who has some limitations in mobility but is not completely immobile. Choice A is incorrect as a patient who is completely immobile would not have impaired physical mobility but rather no physical mobility at all. Choices C and D are also incorrect as they do not directly relate to the defining characteristics of Impaired physical mobility, which involve limitations in movement and physical activity.
