Critical Care Nursing Cardiac Questions

Correct Answer: D

Rationale: The correct answer is D, Living will. A living will is a legal document that outlines a person's preferences for medical treatment if they become unable to communicate their wishes. It specifically addresses life-prolonging procedures. Option A, Do not resuscitate order, is a specific directive to not perform CPR in case of cardiac arrest, not a comprehensive medical care directive. Option B, Healthcare proxy, is a person designated to make medical decisions on behalf of a patient who is unable to do so, not the specific directive itself. Option C, Informed consent, refers to the process of obtaining permission from a patient before conducting a healthcare intervention, not a directive for life-prolonging procedures.

Correct Answer: B

Rationale: The correct answer is B because after 5 days, the risk of infection increases. Evaluating the patient for signs and symptoms of infection is crucial for early detection and treatment. Choice A is incorrect because routine dialysis catheter changes are not necessary after only 5 days. Choice C is incorrect as percutaneous catheters are for short-term use. Choice D is incorrect as using the catheter for fluid administration may increase the risk of infection.

Correct Answer: C

Rationale: The correct answer is C: Insertion of a vena cava filter. This is a strategy for preventing thromboembolism in patients at risk who cannot take anticoagulants. The vena cava filter prevents blood clots from traveling to the lungs by trapping them in the inferior vena cava. It is a mechanical device that does not interfere with the body's clotting process. Explanation of why other choices are incorrect: A: Administration of two aspirin tablets every 4 hours is not an effective strategy for preventing thromboembolism in high-risk patients. Aspirin is an antiplatelet agent and may not be sufficient for preventing blood clots in these patients. B: Infusion of thrombolytics is used for breaking down blood clots that have already formed, not for prevention. It is not a suitable option for preventing thromboembolism in at-risk patients. D: Subcutaneous heparin administration every 12

Correct Answer: A

Rationale: The correct answer is A: One chronic and one acute illness. This is because Type 2 diabetes mellitus is a chronic condition, while influenza is an acute illness. The nurse should develop goals addressing the management and control of the chronic condition (diabetes) as well as the treatment and recovery from the acute illness (influenza). This approach ensures comprehensive care that considers both the long-term management of the chronic illness and the immediate needs related to the acute illness. Choices B, C, and D are incorrect because they do not address the combination of chronic and acute illnesses presented in the scenario. Choice B focuses solely on two acute illnesses, which overlooks the ongoing management required for the chronic condition. Choice C combines an acute and an infectious illness, but fails to account for the chronic illness component. Choice D involves two chronic illnesses, neglecting the immediate care needed for the acute illness.

Correct Answer: A

Rationale: The correct answer is A: Inability to communicate. Critically ill patients often experience pain and anxiety due to their inability to effectively communicate their needs and discomfort. This can lead to unaddressed pain and increased anxiety levels. Choices B, C, and D are incorrect because while invasive procedures, monitoring devices, and preexisting conditions can contribute to pain and anxiety in critically ill patients, they are not factors that directly predispose patients to these issues. It is the lack of communication that significantly hinders the ability to address and manage pain and anxiety effectively in these patients.
