Critical Care Nursing Cardiac Questions Questions
Question 1 of 5
The nurse is caring for a 100-kg patient being monitored with a pulmonary artery catheter. The nurse assesses a blood pressure of 90/60 mm Hg, hear t rate 110 beats/min, respirations 36/min, oxygen saturation of 89% on 3 L of oxygen via nasal cannula. Bilateral crackles are audible upon auscultation. Which hemodynamic value reqaubiirrbe.sco imm/temste diate action by the nurse?
Correct Answer: B
Rationale: The correct answer is B: Cardiac output (CO) of 4 L/min. In this scenario, the patient is presenting with signs of pulmonary congestion and hypoxemia, indicating possible cardiogenic pulmonary edema. As the cardiac output is a key indicator of how well the heart is functioning and delivering blood to the body, a low cardiac output can lead to inadequate tissue perfusion and worsen the patient's condition. Therefore, immediate action is required to address the low cardiac output to improve tissue perfusion and oxygenation. Choices A, C, and D are incorrect as they do not directly address the primary concern of inadequate cardiac output in this patient. Cardiac index, pulmonary vascular resistance, and systemic vascular resistance are important parameters to monitor, but in this case, the priority is to address the low cardiac output to improve the patient's condition.
Question 2 of 5
Which of the following are physiological effects of positive end-expiratory pressure (PEEP) used in the treatment of acute respiratory distress syndrom e (ARDS)? (Select all that apply.)
Correct Answer: A
Rationale: The correct answer is A: Increase functional residual capacity. Positive end-expiratory pressure (PEEP) helps increase the functional residual capacity by keeping the alveoli open at the end of expiration. This prevents alveolar collapse, improves ventilation-perfusion matching, and enhances oxygenation. B: Prevent collapse of unstable alveoli - This is incorrect because PEEP actually helps prevent the collapse of all alveoli, not just unstable ones. C: Improve arterial oxygenation - This is partially correct, but the primary mechanism through which PEEP improves oxygenation is by increasing functional residual capacity. D: Open collapsed alveoli - This is incorrect because PEEP helps prevent alveolar collapse rather than actively opening already collapsed alveoli.
Question 3 of 5
Comparing the patient�s current (home) medications with those ordered during hospitalization and communicating a complete list of medications to the next care provider when the patient is transferred within an organization or to another setting a re strategies toward best achieving what patient related goal?
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.
Question 4 of 5
A nurse is caring for an elderly man recently admitted to the ICU following a stroke. She assesses his cognitive function using a new cognitive assessment test she learned about in a recent article in a nursing journal. She then brings a cup of water and a straw to the patient because she observes that his lips are dry. Later, she has the patient sit in a wheelchair and takes him to have some blood tests performed. He objects at first, saying that he can walk on his own, but the nurse explains that it is hospital policy to use the wheelchair. That evening, she recognizes signs of an imminent stroke in the patient and immediately pages the physician. Which action taken by the nurse is the best example of evidence-based practice?
Correct Answer: C
Rationale: The correct answer is C: Recognizing signs of an imminent stroke and paging the physician. This action exemplifies evidence-based practice as it involves timely identification of a critical medical condition based on clinical assessment and prompt communication with the physician for further intervention. This aligns with the principles of evidence-based practice, which emphasize the integration of best available evidence with clinical expertise and patient values. The other choices are incorrect: A: Giving the patient a cup of water - While providing hydration is important for patient care, it does not demonstrate evidence-based practice in this scenario. B: Transferring the patient in a wheelchair - Although using a wheelchair may be hospital policy, it does not directly relate to evidence-based practice in this context. D: Using the cognitive assessment test - While assessing cognitive function is essential, it does not directly address the immediate medical needs of the patient as recognizing signs of an imminent stroke does.
Question 5 of 5
The nurse cares for a terminally ill patient who is experiencing pain that is continuous and severe. How should the nurse schedule the administration of opioid pain medications?
Correct Answer: A
Rationale: The correct answer is A: Give around-the-clock routine administration of analgesics. This is the best approach for managing continuous and severe pain in a terminally ill patient. By providing scheduled doses of opioid pain medications, the nurse ensures a consistent level of pain relief, preventing peaks and troughs in pain control. This approach also helps in preventing the patient from experiencing unnecessary suffering. Choice B (PRN doses) may lead to inadequate pain control as the patient may wait too long before requesting medication. Choice C (keeping the patient sedated) is not appropriate as the goal is pain management, not sedation. Choice D (balancing pain control and respiratory rate) is important, but the priority should be on effectively managing the pain first.
