Critical Care Nursing Questions Questions
Question 1 of 5
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 2 of 5
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 3 of 5
To maintain proper cuff pressure of an endotracheal tube (ET) when the patient is on mechanical ventilation, the nurse should:
Correct Answer: D
Rationale: The correct answer is D because inflating the cuff until a slight leak is heard only at peak inflation ensures it is adequately sealed but not overinflated, preventing complications like tracheal injury or pressure necrosis. Choice A lacks specificity and can lead to overinflation. Choice B may result in overinflation as the firmness of the balloon is subjective. Choice C relies on a specific pressure reading, which may vary based on factors like tube size and patient anatomy, potentially leading to under- or overinflation.
Question 4 of 5
The nurse assesses a patient who is admitted for an overdo se of sedatives. The nurse expects to find which acid-base alteration?
Correct Answer: B
Rationale: The correct answer is B: Hypoventilation and respiratory acidosis. When a patient overdoses on sedatives, it can lead to respiratory depression causing hypoventilation. Hypoventilation results in retention of CO2, leading to respiratory acidosis. This is because the body is not effectively exhaling CO2, causing an increase in carbonic acid levels and a decrease in blood pH. The other choices are incorrect because hyperventilation would lead to respiratory alkalosis (Choice A), hypoventilation does not cause respiratory alkalosis (Choice C), and normal oxygen levels do not indicate the acid-base imbalance caused by sedative overdose (Choice D).
Question 5 of 5
An elderly patient is admitted to the ICU with stage IV lung cancer, diabetes mellitus, and congestive heart failure. The health care team assembled to care for her is large and diverse, including an oncologist, a pulmonologist, an endocrinologist, a cardiologist, and others. The patient is not expected to survive more than a few weeks, and her husband is overwhelmed with stress and grief. Which nurse competency or competencies are most needed in this situation? Select all that apply.
Correct Answer: B
Rationale: The correct answer is B: Caring practices. In this situation, the patient and her husband are dealing with complex medical conditions and emotional distress. Caring practices involve providing compassionate, empathetic, and supportive care to the patient and her family members during this difficult time. The nurse needs to show sensitivity, understanding, and emotional support to help them cope with their situation. Clinical judgment (A) is important but not the primary focus in this scenario. Collaboration (C) is essential in the interdisciplinary team, but caring practices take precedence in addressing the emotional needs. Response to diversity (D) is also important, but in this case, the focus is more on providing compassionate care rather than addressing cultural or social diversity issues.
