Critical Care Nursing Cardiac Questions Questions

Question 1 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 2 of 5

How should the nurse interprets these blood gas values? 2 3

Correct Answer: C

Rationale: The correct interpretation is uncompensated respiratory acidosis (Choice C) based on the values. Step 1: Evaluate pH - pH is <7.35, indicating acidosis. Step 2: Determine PaCO2 - PaCO2 is >45 mmHg, indicating respiratory cause. Step 3: Check HCO3- - HCO3- is within normal range, indicating uncompensated state. Choices A, B, and D are incorrect because they do not align with the given blood gas values.

Question 3 of 5

Which of the following is (are) official journal(s) of the A merican Association of Critical-Care Nurses? (Select all that apply.)

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.

Question 4 of 5

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.

Question 5 of 5

The nurse is caring for a patient in the critical care unit whaobi,r ba.cfotemr/ tebset ing declared brain dead, is being managed by the OPO transplant coordinator. Thir ty minutes into the shift, assessment by the nurse includes a blood pressure 75/50 mm Hg, hear t rate 85 beats/min, and respiratory rate 12 breaths/min via assist/control ventilation. The oxygen saturation (SpO ) is 99% and 2 core temperature 93.8° F. Which primary care provider ord er should the nurse implement first?

Correct Answer: C

Rationale: The correct answer is C: Begin phenylephrine (Neo-Synephrine) for systolic BP < 90 mm Hg. The nurse should implement this order first because the patient's low blood pressure (75/50 mm Hg) indicates hypotension, which can lead to inadequate perfusion to vital organs. Phenylephrine is a vasoconstrictor that can help increase the patient's blood pressure and improve perfusion. It is crucial to address hypotension promptly to prevent further complications. Choice A is incorrect because maintaining the patient's temperature above 96.8°F is not the most urgent concern in this scenario. Choice B is incorrect as obtaining a basic metabolic panel every 4 hours is not the immediate priority when the patient is experiencing hypotension. Choice D is incorrect as drawing arterial blood gas every 4 hours is not the most urgent intervention needed to address the patient's low blood pressure.
