ATI PN Comprehensive Predictor 2020

Correct Answer: A

Rationale: The correct answer is A. Systolic heart failure is characterized by reduced ejection fraction, meaning the heart is not pumping effectively. Diastolic heart failure, on the other hand, is characterized by preserved ejection fraction, indicating that the heart has difficulty relaxing and filling properly. Choices B, C, and D are incorrect because they do not accurately describe the key differences between systolic and diastolic heart failure.

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: B

Rationale: The correct answer is B: Assess the wound and reposition the patient frequently. When caring for a patient with a pressure ulcer, it is crucial for the nurse to assess the wound regularly to monitor its progress and prevent complications. Additionally, repositioning the patient frequently helps to relieve pressure on the affected area, prevent further damage, and promote healing. Choice A is incorrect because while cleaning the wound is important, applying a protective dressing is not the primary role of the nurse in managing a pressure ulcer. Choice C is incorrect as applying pressure to the ulcer is harmful, and monitoring for signs of healing should not involve applying pressure. Choice D is incorrect as providing pain relief and administering antibiotics may be necessary but are not the primary interventions for managing a pressure ulcer.

Correct Answer: B

Rationale: The correct action for the nurse to take is to report the client's decision to the provider who obtained informed consent. This ensures that the provider is informed of the client's change in decision and can discuss the situation further with the client. Choice A is incorrect as ignoring the client's decision is not appropriate and goes against the principles of patient autonomy. Choice C is incorrect because involving the family in convincing the client can be coercive and may not respect the client's autonomy. Choice D is incorrect because the nurse should not re-sign the informed consent form without the client's consent and a discussion with the provider.

Correct Answer: C

Rationale: Performing a wound culture before applying ointment is crucial when providing wound care to a client with a pressure ulcer. This action helps identify any underlying infections, allowing healthcare providers to select the most appropriate treatment. Options A, B, and D are not as critical as performing a wound culture, as they focus on wound dressing and cleansing rather than identifying potential infections.
