Critical Care Nursing Cardiac Questions Questions

Question 1 of 9

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 9

A 28-year-old patient who has deep human bite wounds on the left hand is being treated in the urgent care center. Which action will the nurse plan to take?

Correct Answer: C

Rationale: The correct answer is C: Teach the patient the reason for the use of prophylactic antibiotics. This is the most important action because human bites can introduce harmful bacteria into the wound, leading to infection. Prophylactic antibiotics help prevent infection in deep human bite wounds. Choice A is incorrect because rabies immune globulin is not indicated for human bite wounds. Choice B is incorrect because suturing human bite wounds can trap bacteria and increase the risk of infection. Choice D is incorrect because keeping the wounds dry is not sufficient; proper wound cleaning and antibiotic treatment are essential in this case.

Question 3 of 9

The nurse is caring for a patient with an admitting diagnosis of congestive failure. While attempting to obtain a pulmonary artery occlusion pressure in the supine position, the patient becomes anxious and tachypneic. What is the best action by the nurse?

Correct Answer: D

Rationale: The correct answer is D: Elevate the head of the bed 45 degrees while recording pressures. Rationale: 1. Elevating the head of the bed will help improve the patient's breathing by reducing the pressure on the diaphragm. 2. This position will also help alleviate the patient's anxiety and tachypnea, promoting better oxygenation. 3. Recording pressures in this position will provide accurate data for monitoring the patient's condition. Summary: A: Limiting the supine position to 10 seconds does not address the underlying issues causing the patient's anxiety and tachypnea. B: Administering anxiety medications without addressing the positioning issue may not effectively manage the patient's symptoms. C: Encouraging the patient to take slow deep breaths is helpful, but changing the position of the patient is more crucial in this situation.

Question 4 of 9

A mode of pressure-targeted ventilation that provides posiatbivirbe. cporme/tsessut re to decrease the workload of spontaneous breathing through what action by the endotracheal tube?

Correct Answer: C

Rationale: The correct answer is C: Pressure support ventilation. This mode delivers a set pressure to support each spontaneous breath, decreasing the workload of breathing. Pressure support ventilation assists the patient's inspiratory efforts without providing a set tidal volume like in volume-targeted ventilation. Continuous positive airway pressure (Choice A) maintains a constant level of positive pressure throughout the respiratory cycle but does not actively support spontaneous breathing efforts. Positive end-expiratory pressure (Choice B) maintains positive pressure at the end of expiration to prevent alveolar collapse but does not directly support spontaneous breathing. T-piece adapter (Choice D) is a weaning device that allows the patient to breathe spontaneously without ventilatory support.

Question 5 of 9

Family members have a need for information. Which intervention best assists in meeting this need?

Correct Answer: B

Rationale: The correct answer is B because providing a daily update of the patient's progress and facilitating communication with the intensivist directly addresses the family members' need for information in a timely and personalized manner. This intervention ensures that the family is kept informed about the patient's condition and treatment plan, fostering transparency and trust. It also allows for any questions or concerns to be addressed promptly, aiding in the family's understanding and involvement in the patient's care. Now, let's summarize why the other choices are incorrect: A: Handing out a pamphlet may provide information, but it lacks the personalized touch and real-time updates that are crucial for meeting the family's need for information. C: Restricting information and only allowing family members to be present at specific times may create frustration and hinder communication, not effectively meeting their information needs. D: Providing a list of medications is helpful, but it does not offer a comprehensive update on the patient's progress or facilitate direct communication with the medical team, which are

Question 6 of 9

The nurse is caring for a patient following insertion of a left subclavian central venous catheter (CVC). Which action by the nurse best reduces th e risk of catheter-related bloodstream infection (CRBSI)?

Correct Answer: A

Rationale: The correct answer is A: Review daily the necessity of the central venous catheter. This action reduces the risk of CRBSI by promoting early removal of unnecessary catheters, which is a key strategy in preventing infections. Unnecessary catheters increase the risk of infection due to prolonged exposure to the patient's skin flora and possible contamination during insertion. Reviewing daily ensures the catheter is only kept when necessary, minimizing the duration of catheter use and reducing the chances of infection. Summary of other choices: B: Cleansing the insertion site daily with isopropyl alcohol is important for maintaining skin integrity but does not directly reduce the risk of CRBSI. C: Changing the pressurized tubing system and flush bag daily is important for maintaining catheter patency but does not directly reduce the risk of CRBSI. D: Maintaining a pressure of 300 mm Hg on the flush bag is important for proper catheter function but does not directly reduce the risk of CR

Question 7 of 9

The charge nurse is responsible for making the patient ass ignments on the critical care unit. She assigns the experienced, certified nurse to care for thea abicrbu.cteomly/t eisltl patient diagnosed with sepsis who also requires continuous renal replacement therapy and mechanical ventilation. She assigns the nurse with less than 1 year of experience to two patients who are more stable. This assignment reflects implementation of what guiding framework?

Correct Answer: D

Rationale: The correct answer is D: Synergy model of practice. The Synergy model emphasizes matching nurse competencies with patient needs for optimal outcomes. In this scenario, the charge nurse assigned the experienced, certified nurse to a complex patient requiring specialized care (sepsis, renal replacement therapy, ventilation), aligning with the model's principle of matching nurse expertise to patient acuity. Assigning the less experienced nurse to stable patients aligns with the model's focus on optimizing patient outcomes by matching nurse competencies appropriately. A: Crew resource management model focuses on teamwork and communication to enhance safety, not specifically on nurse-patient assignments. B: National Patient Safety Goals are broad guidelines for improving patient safety, not specific to nurse-patient assignments. C: Quality and Safety Education for Nurses (QSEN) model focuses on integrating quality and safety competencies into nursing education, not specifically on nurse-patient assignments.

Question 8 of 9

In the critically ill patient, an incomplete assessment and/or management of pain or anxiety may be hampered by which of the following? (Select all that apply.)

Correct Answer: A

Rationale: Step-by-step rationale: 1. Administration of neuromuscular blocking agents can hinder pain or anxiety assessment as it paralyzes the patient, preventing them from communicating discomfort. 2. Delirium may affect the patient's ability to express pain or anxiety, but it does not directly impede assessment and management. 3. Effective nurse communication and assessment skills facilitate, rather than hamper, pain or anxiety assessment. 4. Nonverbal patients can still communicate pain or anxiety through nonverbal cues, so they do not necessarily hinder assessment.

Question 9 of 9

A patient is declared brain dead and a do not resuscitate (DNR) order is put in place. The nurse caring for the patient does not agree with this manne r of care but does not express any concerns to the charge nurse. The nurse’s feeling that the p atient is being killed will likely create what response for this nurse?

Correct Answer: C

Rationale: The correct answer is C: Moral distress. In this scenario, the nurse is experiencing conflicting moral values between the decision made for the patient and their own beliefs. This internal conflict leads to moral distress, a common response when healthcare professionals feel unable to act in accordance with their ethical beliefs. This can lead to emotional turmoil, frustration, and moral residue. A: A sense of abandonment is incorrect because the nurse is still caring for the patient, so there is no physical abandonment. B: Increased family stress is incorrect as the nurse's internal conflict does not directly impact family stress. D: A sense of negligence is incorrect as negligence implies failure to provide proper care, which is not the case here.
