Correct Answer: A

Rationale: Wounds healing by secondary intention involve the gradual filling of the wound with granulation tissue, leading to a higher risk of infection due to prolonged exposure. This makes choice A the correct answer. Choices B and C are incorrect because wounds healing by secondary intention take longer to heal and often result in more pain compared to wounds healing by primary intention. Choice D is also incorrect as wounds healing by secondary intention usually require more frequent dressing changes to prevent infection and promote healing.

Correct Answer: C

Rationale: Measuring the circumference of the left leg is the most appropriate action for an LPN/LVN when assessing a client with a history of DVT and presenting with swelling and pain in the left leg. This measurement helps to assess the extent of swelling objectively and monitor changes in the client's condition. Applying warm compresses (Choice A) may worsen the condition by potentially promoting clot development. Elevating the left leg above the level of the heart (Choice B) is generally recommended for DVT to improve venous return, but measuring the circumference is more appropriate in this scenario. Administering pain medication (Choice D) does not address the underlying issue and should not be the initial action taken.

Correct Answer: A

Rationale: The correct intervention is to assist the client back to bed. A decrease in oxygen saturation while ambulating indicates hypoxemia, and the immediate priority is to stabilize oxygen levels. Returning the client to bed allows for rest and decreased oxygen demand, potentially preventing further desaturation. Encouraging continued ambulation (Choice B) may worsen the hypoxemia by increasing oxygen demand. Obtaining portable oxygen (Choice C) is essential but should not delay addressing the low oxygen saturation. Moving the oximetry probe (Choice D) may not address the underlying cause of decreased oxygen saturation and should not be the first intervention.

Correct Answer: A

Rationale: The nurse is identifying associated manifestations like nausea and vomiting that may occur with the pain. The presence of associated manifestations helps in understanding the broader clinical picture and potential causes of the pain. Location refers to where the pain is felt, pain quality describes the nature of the pain, and aggravating and relieving factors relate to what makes the pain worse or better. In this scenario, the focus is on identifying additional symptoms that can provide important diagnostic clues.

Correct Answer: D

Rationale: In acetaminophen poisoning, liver damage is a significant concern due to the potential for hepatotoxicity. Therefore, the healthcare provider should first review liver enzymes such as AST (aspartate aminotransferase) and ALT (alanine aminotransferase) to assess liver function. Prothrombin time and partial thromboplastin time are coagulation studies and are not the priority in acetaminophen poisoning. Red blood cell and white blood cell counts are important in assessing for anemia or infection but are not specific to acetaminophen poisoning. Blood urea nitrogen and creatinine levels primarily assess kidney function, which is not the primary concern in acetaminophen poisoning.
