Critical Care Nursing Questions

Correct Answer: A

Rationale: The correct answer is A: Alarms that sound from various devices. In the critical care environment, alarms often indicate changes in the patient's condition, causing stress. Bright fluorescent lighting (B) may be bothersome but not directly related to patient stress. Lack of day-night cues (C) may disrupt sleep patterns but is not a direct stressor. Sounds from the mechanical ventilator (D) are essential for patient care and not inherently stressful.

Correct Answer: A

Rationale: The correct answer is A because the patient is a 36-year-old with a Glasgow Coma Scale score of 3 and no activity on electroencephalogram, indicating severe brain injury and likely irreversible neurological damage. This patient meets the criteria for potential organ donation as they are neurologically devastated. Choice B is incorrect because the patient's condition is related to stroke and atrial fibrillation, not severe brain injury that would make them a candidate for organ donation. Choice C is incorrect because although the patient has a brain injury and a lower Glasgow Coma Scale score, the history of a reversible cause (ovarian cancer metastasis) and a higher GCS score compared to choice A make this patient less suitable for organ donation evaluation. Choice D is incorrect as the patient's diabetic and cardiovascular history does not suggest severe brain injury that would qualify for organ donation.

Correct Answer: A

Rationale: The correct answer is A: Assess the patient's current vital signs. The nurse's first action should be to gather objective data to assess the patient's condition and determine the urgency of the situation. Vital signs, including temperature, heart rate, blood pressure, and respiratory rate, provide crucial information for the initial assessment. This will help the nurse identify any signs of sepsis, shock, or other serious conditions that require immediate intervention. The other choices are incorrect because: B: Giving acetaminophen without assessing the patient's vital signs and determining the cause of the symptoms could mask important clinical information and delay appropriate treatment. C: While obtaining a urine sample may be necessary later to rule out a urinary tract infection, it is not the most immediate priority in this case. D: Delaying the patient's assessment and care based on estimated wait times is not appropriate when the patient presents with potentially serious symptoms. Immediate evaluation is required in this scenario.

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.

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.
