Critical Care Nursing Questions Questions
Question 1 of 9
What factors may predispose a patient to respiratory acido as bi is rb? . com/test
Correct Answer: B
Rationale: The correct answer is B: Central nervous system depression. This factor can lead to respiratory acidosis by depressing the respiratory drive, causing hypoventilation and retention of carbon dioxide. Anxiety and fear (A) may lead to hyperventilation, reducing carbon dioxide levels. Diabetic ketoacidosis (C) results in metabolic acidosis, not respiratory acidosis. Nasogastric suctioning (D) may cause respiratory alkalosis from excessive removal of carbon dioxide. Thus, central nervous system depression is the most likely factor predisposing a patient to respiratory acidosis.
Question 2 of 9
A patients family is exhibiting increasingly impaired coping as the patients condition deteriorates. The nurse asks the family to state the biggest concern from their perspective.What is the most important rationale for this question?
Correct Answer: C
Rationale: The correct answer is C because asking the family to state their biggest concern clarifies the nurse's understanding of the current family needs. This step allows the nurse to assess the specific areas where the family may require support or assistance, leading to more tailored interventions. By identifying the primary concern, the nurse can better address the family's emotional, informational, or practical needs. Choice A is incorrect because the question is not solely about active listening; it serves a deeper purpose of assessment. Choice B is incorrect as the question goes beyond validating knowledge to understanding emotional and practical needs. Choice D is incorrect because the question focuses on identifying concerns rather than defining the degree of understanding.
Question 3 of 9
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?
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.
Question 4 of 9
A patient’s ventilator settings are adjusted to treat hypoxemia. The fraction of inspired oxygen is increased from.60 to.70, and the positive end-expiratory pressure is increased from 10 to 15 cm H O. Shortly after these adjustments, the nurse notes that the patient’s blood pressure drops from 120/76 mm Hg to 90/60 mm Hg. What is the m ost likely cause of this decrease in blood pressure?
Correct Answer: B
Rationale: The correct answer is B: Hypovolemia. When the ventilator settings are adjusted to treat hypoxemia by increasing FiO2 and PEEP, it can lead to increased oxygenation but also potentially decrease venous return to the heart, causing a decrease in blood pressure. This decrease in blood pressure is most likely due to hypovolemia, as the increased PEEP can increase intrathoracic pressure, reducing venous return and preload, leading to a decrease in cardiac output and subsequent decrease in blood pressure. This choice is the most likely cause as the other options (A: Decrease in cardiac output, C: Increase in venous return, D: Oxygen toxicity) do not directly correlate with the changes in ventilator settings described in the question.
Question 5 of 9
A patient is admitted to the emergency department (ED) after falling through the ice while ice skating. Which assessment will the nurse obtain first?
Correct Answer: C
Rationale: The correct answer is C: Body temperature. In a patient who has fallen through the ice, hypothermia is a major concern due to exposure to cold water. Assessing body temperature first is crucial to determine the severity of hypothermia and guide immediate interventions. Heart rate, breath sounds, and level of consciousness can be affected by hypothermia but are secondary assessments. Assessing body temperature is the priority to address the most life-threatening issue first.
Question 6 of 9
Slow continuous ultrafiltration is also known as isolated ultrafiltration and is used to
Correct Answer: A
Rationale: The correct answer is A because slow continuous ultrafiltration removes excess plasma water in cases of volume overload by applying a pressure gradient across a semipermeable membrane. This process helps to achieve fluid balance without removing solutes. Choice B is incorrect because convection is not the primary mechanism of slow continuous ultrafiltration. Choice C is incorrect as dialysate is not added in slow continuous ultrafiltration. Choice D is incorrect as slow continuous ultrafiltration does not combine all three processes of ultrafiltration, convection, and dialysis.
Question 7 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 8 of 9
Which of the following are accepted nonpharmacological approaches to managing pain and/or anxiety in critically ill patients? (Select all that apply.)
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.
Question 9 of 9
A 65-year-old patient with a history of metastatic lung car cinoma has been unresponsive to chemotherapy. The medical team has determined that ther e are no additional treatments available that will prolong life or improve the quality of lifaebi ribn.c oamn/yte smt eaningful way. Despite the poor prognosis, the patient continues to receive chemotherapy and full nutrition support. This is an example of what end-of-life concept?
Correct Answer: A
Rationale: The correct answer is A: Medical futility. In this scenario, the patient's condition is terminal with no treatment options left. Continuing chemotherapy offers no benefit and may even harm the patient. Medical futility refers to interventions that are unlikely to achieve the desired outcome. B: Palliative care focuses on improving quality of life for patients with serious illnesses, which is not being addressed in this case. C: Terminal weaning involves gradually removing life-support measures, which is not happening here. D: Withdrawal of treatment would be appropriate if the treatments were no longer beneficial, but the issue here is the continued provision of futile treatment.
