Critical Care Nursing Cardiac Questions

Correct Answer: C

Rationale: Step 1: Reconciling medications is essential for patient safety as it involves comparing current and ordered medications to ensure accuracy. Step 2: This process helps prevent medication errors, adverse drug reactions, and duplications across different care settings. Step 3: Communicating a complete list of medications to the next care provider ensures continuity of care and reduces the risk of medication discrepancies. Step 4: By reconciling medications across the continuum of care, healthcare providers can better coordinate patient care and optimize treatment outcomes. In summary, choice C is correct as it focuses on medication reconciliation to improve patient safety and care coordination. Choices A, B, and D are incorrect as they do not directly address the comprehensive process of reconciling medications across care settings.

Correct Answer: A

Rationale: The correct answer is A: Apply wet sheets and a fan to the patient. This is the initial treatment for hyperthermia to aid in lowering the body temperature. Wet sheets help in evaporative cooling, while a fan enhances heat loss through convection. This approach is crucial in managing heat-related illnesses quickly. Choices B, C, and D are incorrect as they do not directly address the urgent need to reduce the patient's elevated core temperature. Providing O2, IV fluids, or acetaminophen can be considered later in the management, but the priority is to rapidly lower the body temperature in a hyperthermic patient to prevent further complications.

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: C

Rationale: The correct answer is C: The beeping of the heart monitor is a likely stressor for the patient recovering from open-heart surgery in the ICU. The constant beeping can cause anxiety and uncertainty about their health status. The daughter's conversation and effleurage are likely comforting and supportive for the patient, reducing stress. The dim lighting may create a calming environment, and the distant cries of a patient in pain may evoke empathy but may not directly stress the recovering patient. Therefore, the beeping of the heart monitor stands out as a stressor among the choices provided.

Correct Answer: A

Rationale: The correct answer is A: Advance directive. An advance directive is a legal document that outlines a person's wishes regarding medical treatment and care at the end of life. It allows individuals to specify their preferences for medical interventions if they become unable to communicate. Summary of other choices: B: Guardianship ad item - This does not specifically pertain to an individual's end-of-life care wishes. C: Healthcare proxy - While similar to an advance directive, a healthcare proxy specifically designates a person to make medical decisions on behalf of the individual, rather than specifying their own wishes. D: Power of attorney - This grants someone the authority to make legal decisions on behalf of the individual, but it does not specifically address end-of-life care preferences.
