Critical Care Nursing Cardiac Questions Questions
Question 1 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 2 of 9
A patient in the ICU is recovering from open-heart surgery. The nurse enters his room and observes that his daughter is performing effleurage on his arms and talking in a low voice about an upcoming family vacation that is planned. The room is dimly lit, and she hears the constant beeping of his heart monitor. From the hall she hears the cries of a patient in pain. Which of the following are likely stressors for the patient? Select all that apply.
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.

Question 4 of 9
Conditions that produce acute kidney injury by directly acting on functioning kidney tissue are classified as intrarenal. The most common intrarenal condition is
Correct Answer: C
Rationale: Rationale: 1. Acute tubular necrosis (ATN) is the most common intrarenal condition as it directly affects kidney tubules. 2. ATN is characterized by damage to renal tubular cells due to various factors like toxins or ischemia. 3. Prolonged ischemia (choice A) can lead to ATN but is not the most common intrarenal condition. 4. Exposure to nephrotoxic substances (choice B) can cause ATN, but ATN itself is more common. 5. Hypotension for several hours (choice D) can result in ischemia and subsequent ATN, but ATN is still the primary intrarenal condition.
Question 5 of 9
Which statement regarding ethical concepts is true?
Correct Answer: C
Rationale: Rationale: Choice C is correct because a surrogate is indeed a competent adult designated to make healthcare decisions for an incapacitated person. This individual is typically chosen by the person themselves through a legal document like a healthcare proxy. This ensures that someone trusted can make important decisions when the person is unable to do so. Choices A, B, and D are incorrect because a living will and healthcare proxy serve different purposes, a signed donor card does not guarantee organ donation in the event of brain death (medical criteria are also required), and a persistent vegetative state is different from brain death (brain death implies irreversible cessation of brain function while a vegetative state involves some level of brain function).
Question 6 of 9
The nurse is caring for a patient receiving intravenous ibup rofen for pain management. The nurse recognizes which laboratory assessment to be a possaibbirlbe.c soimd/ete set ffect of the ibuprofen?
Correct Answer: A
Rationale: The correct answer is A: Elevated creatinine. Ibuprofen can cause kidney damage, leading to elevated creatinine levels. This is because ibuprofen is metabolized in the kidneys, and prolonged use can impair kidney function. Elevated platelet count (B), elevated white blood count (C), and low liver enzymes (D) are not typically associated with ibuprofen use. Platelet count and white blood count are more related to inflammation or infection, while low liver enzymes are not a common side effect of ibuprofen.
Question 7 of 9
When assisting with the placement of a pulmonary artery (PA) catheter, the nurse notes that the catheter is correctly placed when the monitor shows a:
Correct Answer: D
Rationale: Step-by-step rationale for Answer D being correct: 1. PA catheter measures PA pressures. 2. PAWP reflects left atrial pressure. 3. Correct placement shows typical PAWP tracing. 4. PA pressure waveform (A) is not specific to PAWP. 5. Systemic arterial pressure tracing (B) is unrelated. 6. Systemic vascular resistance tracing (C) is not monitored by PA catheter.
Question 8 of 9
Which interventions may be included during “terminal we aning”? (Select all that apply.)
Correct Answer: B
Rationale: The correct answer is B because during terminal weaning, the artificial ventilation is discontinued while maintaining the artificial airway to ensure comfort and support. This allows the patient to breathe on their own with support as needed. Explanation: 1. Option A: Complete extubation following ventilator withdrawal may not be suitable during terminal weaning as it involves removing the breathing tube entirely. 2. Option C: Discontinuation of anxiolytic and pain medications may not always be appropriate during terminal weaning as it depends on the patient's comfort needs. 3. Option D: Titration of ventilator support based on blood gas determinations is not typically done during terminal weaning as the focus is on gradual withdrawal of ventilation support while maintaining comfort.
Question 9 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
