ATI PN Comprehensive Predictor 2020

Correct Answer: B

Rationale: Performing a wound culture before applying antibiotics is crucial for determining the specific type of infection present and selecting the most effective antibiotic treatment. Changing the dressing daily (Choice A) is a routine wound care practice but may not address the root cause of the infection. Cleansing the wound with alcohol-based solutions (Choice C) can be too harsh and delay wound healing. Applying a wet-to-dry dressing (Choice D) is an outdated practice that can cause trauma to the wound bed and hinder the healing process.

Correct Answer: D

Rationale: The correct answer is D because it accurately transcribes the prescription by specifying the medication (Potassium chloride), the dose (20 mEq), the route (PO for by mouth), and the frequency (every morning). Choice A is incorrect as it specifies a lower dose compared to the correct prescription. Choice B is incorrect due to an inaccurate dose. Choice C is incorrect as it lacks specificity regarding the type of potassium prescribed and the dose.

Correct Answer: B

Rationale: The correct instruction the nurse should include is to 'Stop exercising if pain occurs.' In peripheral arterial disease (PAD), it is crucial to avoid exercising to the point of pain as this may worsen the condition and lead to complications. Exercising to the point of pain can result in inadequate blood flow to the extremities, causing further damage. By stopping exercise if pain occurs, the client can prevent exacerbating their condition. Choices A, C, and D are incorrect because exercising to the point of pain, limiting exercise to once per week, and avoiding walking altogether are not recommended strategies for managing PAD and could potentially harm the client.

Correct Answer: C

Rationale: The correct intervention for a client experiencing chronic pain is to teach relaxation techniques, as it helps in managing pain more effectively by reducing stress and anxiety. Distractions like television (Choice A) may offer temporary relief but do not address the root cause of chronic pain. Administering pain medication around the clock (Choice B) may lead to dependency and not promote long-term pain management. While massage therapy (Choice D) can be beneficial, teaching relaxation techniques (Choice C) is more directly focused on empowering the client to manage their pain independently.

Correct Answer: B

Rationale: Performing a wound culture before administering antibiotics is crucial when managing a client with a wound infection. This step helps identify the specific pathogens causing the infection, allowing for the prescription of the most effective antibiotics. Changing the wound dressing every 24 hours (Choice A) is important for wound care but not the priority when an infection is present. Cleansing the wound with alcohol-based solutions (Choice C) can be too harsh and may delay wound healing. Applying a wet-to-dry dressing (Choice D) is not recommended for infected wounds as it can cause trauma to the wound bed during dressing changes.
