Critical Care Nursing Questions and Answers PDF Questions
Question 1 of 9
Sleep often is disrupted for critically ill patients. Which nu rsing intervention is most appropriate to promote sleep and rest?
Correct Answer: A
Rationale: The correct answer is A: Consult with the pharmacist to adjust medication times to allow periods of sleep or rest between intervals. This is the most appropriate intervention as medication timings can significantly impact sleep patterns of critically ill patients. Adjusting medication times can help synchronize rest periods, promoting uninterrupted sleep. Choice B is incorrect as encouraging constant conversation can disrupt sleep. Choice C is incorrect as the television noise can be stimulating and hinder rest. Choice D is incorrect as leaving the lights on can disrupt the patient's circadian rhythm and negatively impact sleep quality.
Question 2 of 9
The nurse aware that a shortage of organs exists knows that which statement is true?
Correct Answer: B
Rationale: Rationale for Correct Answer (B - Brain death determination is required before organs can be retrieved for transplant): 1. Brain death determination is a medical necessity to ensure the organs are viable for transplant. 2. Organs must be retrieved promptly after brain death to maintain their functionality. 3. Brain death criteria ensure that the donor is truly deceased before organ retrieval. Summary of Why Other Choices are Incorrect: A: While discussing organ donation is important, comfort level is not the main factor in organ shortage awareness. C: Donation after cardiac death is ethically acceptable, but it is not directly related to the need for brain death determination. D: Withdrawing life support solely to become an organ donor is ethically questionable and not a necessary step in organ donation.
Question 3 of 9
The emergency department (ED) nurse is initiating therapeutic hypothermia in a patient who has been resuscitated after a cardiac arrest. Which actions in the hypothermia protocol can be delegated to an experienced licensed practical/vocational nurse (LPN/LVN) (select all that apply)?
Correct Answer: D
Rationale: Correct Answer: D - Give acetaminophen (Tylenol) 650 mg per nasogastric tube. Rationale: LPNs/LVNs are trained to administer medications, including oral and nasogastric routes. Giving acetaminophen via nasogastric tube is within their scope of practice. LPNs/LVNs should have the knowledge and skills to safely administer this medication as part of the hypothermia protocol. Summary of other choices: A: Continuously monitor heart rhythm - This requires specialized training and skills typically within the scope of registered nurses or cardiac monitoring technicians. B: Check neurologic status every 2 hours - Assessing neurologic status requires critical thinking and clinical judgment, which are typically responsibilities of registered nurses. C: Place cooling blankets above and below the patient - Positioning and managing cooling devices may require specific training and should be done under the supervision of a registered nurse.
Question 4 of 9
The nurse calculates the PaO /FiO ratio for the following values: PaO is 78 mm Hg; FiO is 2 2 2 2 6 (60%). What is the outcome and the relationship to the ARDS diagnosing criteria?
Correct Answer: A
Rationale: The correct answer is A: 46.8; meets criteria for ARDS. The PaO /FiO ratio is calculated by dividing the arterial oxygen partial pressure (PaO) by the fraction of inspired oxygen (FiO). In this case, PaO is 78 mm Hg and FiO is 0.6 (60%). Therefore, the calculation would be 78/0.6 = 130. This value is less than 300, which is indicative of ARDS according to the Berlin criteria. Choices B and C are incorrect as they do not align with the criteria for ARDS. Choice D is incorrect because the data provided is sufficient to compute the ratio.
Question 5 of 9
What is the focus of the synergy model of practice?
Correct Answer: C
Rationale: The correct answer is C because the synergy model of practice emphasizes considering the needs of patients and their families, which in turn drives nursing competency. This approach recognizes that patient care is not just about the individual but also about the broader support system. This holistic viewpoint helps nurses tailor their care to meet the unique needs of each patient and their family, ultimately leading to better outcomes. Choices A, B, and D are incorrect: A: Allowing unrestricted visiting for the patient 24 hours is not directly related to the focus of the synergy model which is more about patient-centered care. B: Providing holistic and alternative therapies is a valid approach, but it is not the primary focus of the synergy model. D: Addressing the patients' needs for energy and support is important but does not capture the comprehensive nature of the synergy model which encompasses the needs of both patients and their families.
Question 6 of 9
A nurse decides to seek certification in critical care nursing. What is the most important benefit for the individual nurse in becoming certified in a specialty?
Correct Answer: C
Rationale: The correct answer is C because obtaining certification in critical care nursing demonstrates the nurse's personal expertise in the specialty. Certification confirms the nurse's advanced knowledge and skills, enhancing professional credibility and potential for career advancement. This choice focuses on the individual nurse's competency and dedication to the specialty. Incorrect choices: A: Salary increase is not the primary benefit of certification, although it may be a potential outcome. B: Certification is often preferred but not always required to work in critical care. D: Employers may encourage certification, but it is not always mandated.
Question 7 of 9
The nurse is caring for a patient admitted with a traumatic brain injury following a motor vehicle crash. The patient’s Glasgow Coma Score is 3 anda binirbte.cromm/ittetset ntly withdraws when painful stimuli are introduced. The patient is ventilator dependent and occasionally takes a spontaneous breath. The primary care provider explains to the family that the patient has severe neurological impairment and it is not expected that the patient will ever recover consciousness. What concept does this situation depict?
Correct Answer: C
Rationale: The correct answer is C: A persistent vegetative state. This choice is correct because the patient exhibits minimal responsiveness, only withdrawing to painful stimuli, and lacks meaningful interaction or consciousness. A persistent vegetative state is characterized by preserved wakefulness without awareness, which aligns with the patient's condition. Choice A: An organ donor is incorrect because the patient's neurological impairment does not necessarily indicate readiness for organ donation. Choice B: Brain death is incorrect because the patient still exhibits some reflexive responses, indicating a level of brain function beyond brain death. Choice D: Terminally ill is incorrect as it does not specifically address the patient's neurological status and prognosis, which is better described by a persistent vegetative state.
Question 8 of 9
The nurse notes that a patient’s endotracheal tube (ET), which was at the 22 cm mark, is now at the 25 cm mark and the patient is anxious and restless. Which action should the nurse take next?
Correct Answer: C
Rationale: The correct answer is C: Listen to the patient’s breath sounds. Moving from 22 cm to 25 cm may indicate ET tube migration. Checking breath sounds can confirm proper tube placement. A may not address the underlying issue. B could worsen the situation if the tube is misplaced. D is not urgent compared to assessing airway integrity.
Question 9 of 9
Which of the following statements describes the core conc ept of the synergy model of practice?
Correct Answer: D
Rationale: Rationale: D is correct because the synergy model focuses on individualized care based on patients' unique needs. This model emphasizes tailoring nursing competencies to address these needs, promoting holistic care. A is incorrect as certification is not a requirement. B involves family inclusion but does not capture the core concept. C mentions collaboration but does not specifically address individualized care.
