A patient who has been declared brain dead is considered a potential organ donor. In order to proceed with donation, the nurse must understand that applicable concept?
- A. A signed donor card mandates that organs be retrieved in the event of brain death.
- B. After brain death has been determined, perfusion and o xygenation of organs is maintained until organs can be removed in the operatin ag bi rbro .co omm /t. e st
- C. The healthcare proxy does not need to give consent for the retrieval of organs.
- D. Once a patient has been established as brain dead, life support is withdrawn and organs are retrieved.
Correct Answer: B
Rationale: The correct answer is B because after brain death is confirmed, maintaining perfusion and oxygenation of organs is crucial to ensure their viability for donation. This process allows organs to be retrieved in optimal condition during the operation. Choice A is incorrect because a signed donor card is not a legal mandate for organ retrieval. Choice C is incorrect as the healthcare proxy's consent is typically required for organ donation. Choice D is incorrect because life support is not immediately withdrawn upon brain death confirmation; instead, organ preservation measures are initiated.

Which of the following are accepted nonpharmacological approaches to managing pain and/or anxiety in critically ill patients? (Select all that apply.)
- A. Environmental manipulation
- B. Explanations of monitoring equipment
- C. Guided imagery
- D. Music therapy
Correct Answer: A
Rationale: Step 1: Environmental manipulation involves adjusting factors like lighting, noise levels, and room temperature to create a soothing environment, which can help reduce pain and anxiety.
Step 2: By controlling the physical surroundings, patients may feel more comfortable and relaxed, leading to improved pain management and reduced anxiety levels.
Step 3: Explanations of monitoring equipment and guided imagery are not directly related to environmental changes that can impact pain and anxiety.
Step 4: Music therapy, while beneficial for some patients, is not categorized as environmental manipulation.
The nurse caring for a mechanically ventilated patient note s the high pressure alarm sounding but cannot quickly identify the cause of the alarm. The nurasbeir bn.cootme/ste stht e patient’s oxygen saturation is decreasing and heart rate and respiratory rate are increasing. What is the nurse’s priority action?
- A. Ask the respiratory therapist to get a new ventilator
- B. Call the rapid response team to assess the patient
- C. Continue to find the cause of the alarm and fix it
- D. Manually ventilate the patient while calling for a respi ratory therapist
Correct Answer: B
Rationale: The correct answer is B. The nurse's priority is to ensure the patient's safety and well-being. Calling the rapid response team will allow for immediate assessment by a team of healthcare professionals to address the deteriorating condition. This step takes precedence over troubleshooting the ventilator or manually ventilating the patient. Asking for a new ventilator (A) or manually ventilating the patient (D) does not address the urgent need for a comprehensive assessment and intervention. Continuing to troubleshoot the alarm (C) can delay critical interventions needed for the patient's worsening condition. Thus, calling the rapid response team is the most appropriate action to address the escalating clinical situation promptly.
The patient is receiving neuromuscular blockade. Which nursing assessment indicates a target level of paralysis?
- A. Glasgow Coma Scale score of 3
- B. Train-of-four yields two twitches
- C. Bispectral index of 60
- D. CAM-ICU positive
Correct Answer: B
Rationale: The correct answer is B: Train-of-four yields two twitches. This assessment indicates a target level of paralysis because a train-of-four ratio of 2 twitches out of 4 suggests a 50% neuromuscular blockade, which is often the goal for patients receiving paralysis for procedures or ventilation.
A: A Glasgow Coma Scale score of 3 assesses consciousness, not neuromuscular blockade.
C: A Bispectral index of 60 measures depth of anesthesia, not paralysis level.
D: CAM-ICU assesses delirium, not neuromuscular blockade.
When caring for a patient who has an arterial catheter in the left radial artery for arterial pressure-based cardiac output (APCO) monitoring, which information obtained by the nurse is most important to report to the health care provider?
- A. The patient has a positive Allen test.
- B. There is redness at the catheter insertion site.
- C. The mean arterial pressure (MAP) is 86 mm Hg.
- D. The dicrotic notch is visible in the arterial waveform.
Correct Answer: B
Rationale: The correct answer is B: There is redness at the catheter insertion site. Redness at the catheter insertion site could indicate infection, which is a serious complication that requires immediate attention to prevent sepsis. Reporting this to the healthcare provider promptly is crucial for timely intervention. Choices A, C, and D are not as urgent. A positive Allen test (choice A) assesses collateral circulation and is important for assessing perfusion before arterial cannulation but does not require immediate intervention. Choice C (MAP is 86 mm Hg) falls within the normal range, so it does not indicate an urgent issue. The visibility of the dicrotic notch in the arterial waveform (choice D) is a normal finding and does not require immediate action.
The nurse is caring for a patient with severe neurological impairment following a massive stroke. The primary care provider has ordered tests to detearbmirbi.ncoem b/treasit n death. The nurse understands that criteria for brain death includes what crite ria? (Select all that apply.)
- A. Absence of cerebral blood flow.
- B. Absence of brainstem reflexes on neurological examin ation.
- C. Presents of Cheyne-Stokes respirations.
- D. Confirmation of a flat electroencephalogram.
Correct Answer: A
Rationale: The correct answer is A: Absence of cerebral blood flow. Brain death is determined by the irreversible cessation of all brain functions, including blood flow to the brain. When there is no cerebral blood flow, the brain is unable to function, leading to brain death. This criterion is essential in diagnosing brain death as it indicates a complete loss of brain function.
Explanation for why the other choices are incorrect:
- B: Absence of brainstem reflexes on neurological examination is a common sign of brain death, but it is not the primary criterion.
- C: Presence of Cheyne-Stokes respirations is not indicative of brain death. It is a pattern of breathing that can be seen in various conditions, not specifically brain death.
- D: Confirmation of a flat electroencephalogram is a supportive test for brain death but not the primary criterion. The absence of brain activity on an EEG can help confirm brain death but is not as definitive as the absence of cerebral blood flow.
