Which interventions may be included during “terminal we aning”? (Select all that apply.)
- A. Complete extubation following ventilator withdrawal
- B. Discontinuation of artificial ventilation but maintenanc e of the artificial airway
- C. Discontinuation of anxiolytic and pain medications
- D. Titration of ventilator support based upon blood gas de terminations
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.

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?
- A. Giving the patient a cup of water
- B. Transferring the patient in a wheelchair
- C. Recognizing signs of imminent stroke and paging the physician
- D. Using the cognitive assessment test
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.
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:
- A. Typical PA pressure waveform.
- B. Tracing of the systemic arterial pressure.
- C. Tracing of the systemic vascular resistance.
- D. Typical PA wedge pressure (PAWP) tracing.
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.
The patient diagnosed with acute respiratory distress synd rome (ARDS) would exhibit which symptom?
- A. Decreasing PaO levels despite increased FiO adminis tration
- B. Elevated alveolar surfactant levels
- C. Increased lung compliance with increased FiO administration 2
- D. Respiratory acidosis associated with hyperventilation
Correct Answer: A
Rationale: The correct answer is A because in ARDS, there is a severe impairment in gas exchange leading to hypoxemia. Decreasing PaO2 levels despite increased FiO2 administration indicate poor oxygenation, a hallmark of ARDS. Elevated alveolar surfactant levels (Choice B) do not directly correlate with ARDS pathophysiology. Increased lung compliance with increased FiO2 administration (Choice C) is not characteristic of ARDS, as ARDS leads to decreased lung compliance. Respiratory acidosis associated with hyperventilation (Choice D) is not a typical finding in ARDS, as hyperventilation is usually present in an attempt to compensate for hypoxemia.
Which of the following is (are) official journal(s) of the A merican Association of Critical-Care Nurses? (Select all that apply.)
- A. American Journal of Critical Care
- B. Critical Care Clinics of North America
- C. Critical Care Nurse
- D. Critical Care Nursing Quarterly
Correct Answer: A
Rationale: Step-by-step rationale:
1. The American Association of Critical-Care Nurses (AACN) publishes the American Journal of Critical Care (AJCC).
2. The AJCC is a peer-reviewed journal that covers critical care nursing practice, research, and education.
3. The content in AJCC aligns with AACN's mission and standards for critical care nursing.
4. Hence, AJCC is an official journal of AACN.
Summary of other choices:
- B: Critical Care Clinics of North America - Not an official journal of AACN.
- C: Critical Care Nurse - Not an official journal of AACN.
- D: Critical Care Nursing Quarterly - Not an official journal of AACN.
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?
- A. Cardiac index (CI) of 1.2 L/min/m3
- B. Cardiac output (CO) of 4 L/min
- C. Pulmonary vascular resistance (PVR) of 80 dynes/sec/cm5
- D. Systemic vascular resistance (SVR) of 1800 dynes/sec /cm5
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.
