Critical Care Nursing Questions Questions
Question 1 of 9
A patient in the ICU is complaining that he is not sleeping well at night because of anxiety. Which of the following would be the most helpful intervention for the nurse to make?
Correct Answer: C
Rationale: Rationale: C: Providing the patient with 5 minutes of effleurage (gentle massage) and minimizing disruptions is the most helpful intervention. Effleurage can help reduce anxiety and promote relaxation, improving sleep quality. Minimizing disruptions creates a conducive environment for sleep. A: Providing a bath after REM sleep may disrupt the patient's sleep cycle, worsening anxiety. B: Increasing pain medication may not address the root cause of anxiety and could lead to dependency or side effects. D: Monitoring brain waves with polysomnography is an invasive procedure not typically indicated for managing anxiety-related sleep issues.
Question 2 of 9
The nurse understands that a patient being cared for in a critical care unit experiences anacute stress response. What nursing action best demonstrates understanding of the physiological parts of the initial stress response?
Correct Answer: C
Rationale: The correct answer is C: Treatment for elevated blood pressure. In the initial stress response, the body releases adrenaline and cortisol, leading to increased heart rate and blood pressure. Treating elevated blood pressure is crucial to prevent complications like heart attack or stroke. Adequate pain control (A) and intravenous sedation (B) may help manage symptoms but do not directly address the physiological response to stress. Ignoring an elevated glucose level (D) is not recommended as stress can impact blood sugar levels. Treatment for elevated blood pressure directly targets the physiological response to stress, making it the best nursing action in this scenario.
Question 3 of 9
Following insertion of a pulmonary artery catheter (PAC),a bthirbe. cpohmy/tessitc ian orders the nurse to obtain a blood sample for mixed venous oxygen saturation (SvO ). Which action by the nurse best ensures the obtained value is accurate?
Correct Answer: B
Rationale: The correct answer is B because calibrating the system with central venous and arterial blood samples ensures accuracy of the mixed venous oxygen saturation (SvO2) measurement. This calibration allows for comparison of the values obtained from both sources to confirm the accuracy of the measurement. Choice A is incorrect because zero referencing the transducer at the level of the phlebostatic axis does not directly address the accuracy of the SvO2 measurement. Choice C is incorrect because ensuring patency of the catheter using normal saline pressurized at 300 mm Hg does not directly impact the accuracy of the SvO2 measurement. Choice D is incorrect because using noncompliant pressure tubing does not ensure the accuracy of the SvO2 measurement. The length of the tubing and the presence of stopcocks are not directly related to obtaining an accurate SvO2 value.
Question 4 of 9
The nurse caring for a critically ill patient implements several components of care. What component is an example of the use of evidence-based practice?
Correct Answer: B
Rationale: The correct answer is B because applying an insulin sliding scale method based on research is an example of evidence-based practice. This method is derived from scientific evidence and research studies, ensuring the best outcomes for the patient. The other choices lack the same level of evidence-based rationale: A is based on a protocol, which may not be evidence-based; C is a standard safety practice, not necessarily evidence-based; D is a decision based on hospital policy or practicality, not specifically evidence-based.
Question 5 of 9
Which patient should the nurse notify the organ procureme nt organization (OPO) to evaluate for possible organ donation?
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.
Question 6 of 9
What were identified as the first critical care units? (Select all that apply.)
Correct Answer: A
Rationale: The correct answer is A: Burn units. Burn units were identified as the first critical care units due to the complex and intensive care required by burn patients. These units were established to provide specialized care for burn victims, including wound management, infection control, and fluid resuscitation. Summary: - Burn units were the first critical care units due to the specialized care needed for burn patients. - Coronary care units focus on cardiac conditions, not the first identified critical care units. - Recovery rooms are for post-operative care, not specifically for critical care. - Neonatal intensive care units are specialized for newborns, not the first critical care units.
Question 7 of 9
The American Nurses Credential Center Magnet Recognition Program supports many actions to ensure that nurses are engaged and empowered to participate in ethical decision making. Which of the following would assist nurses in being involvabeirdb .icnom r/etesset arch studies?
Correct Answer: A
Rationale: Rationale: A: Education on protection of human subjects is crucial for nurses to understand ethical principles when conducting research studies. It ensures compliance with ethical guidelines and protection of research participants. B: Participation of staff nurses on ethics committees is not directly related to conducting research studies and may not specifically involve protection of human subjects. C: Written descriptions of how nurses participate in ethics programs do not necessarily focus on research studies and may not cover the specific ethical considerations required in research. D: Written policies and procedures related to response to ethical issues are important but may not provide the necessary knowledge on protection of human subjects for conducting research studies.
Question 8 of 9
A nurse is weaning a 68-kg male patient who has chronic obstructive pulmonary disease (COPD) from mechanical ventilation. Which patient assessment finding indicates that the weaning protocol should be stopped?
Correct Answer: C
Rationale: The correct answer is C because a respiratory rate of 32 breaths/min indicates increased work of breathing, which could be a sign of respiratory distress. In a patient being weaned from mechanical ventilation, an elevated respiratory rate suggests that the patient may not be able to sustain adequate ventilation on their own. This warrants stopping the weaning protocol to prevent respiratory failure. Choice A is incorrect because a heart rate of 97 beats/min is within normal range for an adult. Choice B is incorrect because an oxygen saturation of 93% is acceptable for a patient with COPD. Choice D is incorrect because a tidal volume of 450 mL is adequate for a patient weaning from mechanical ventilation.
Question 9 of 9
The nurse cares for a patient with lung cancer in a home hospice program. Which action by the nurse is most appropriate?
Correct Answer: B
Rationale: The correct answer is B because in a home hospice program, it is essential for the nurse to provide holistic care that includes addressing the patient's emotional and psychological needs. Encouraging the patient to discuss past life events and their meaning can help them process emotions, find closure, and improve their quality of life. This approach aligns with the principles of palliative care, which focus on enhancing comfort and well-being. Choice A is incorrect because discussing cancer risk factors and lifestyle modifications may not be relevant or beneficial for a patient in a hospice program. Choice C is incorrect because chemotherapy and radiation are typically not part of hospice care, which focuses on comfort rather than curative treatments. Choice D is incorrect because a thorough head-to-toe assessment multiple times a week may not be necessary or appropriate for a patient in a hospice program.
