Critical Care Nursing Questions Questions
Question 1 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 2 of 9
The patient undergoes a cardiac catheterization that requires the use of contrast dyes during the procedure. To detect signs of contrast-induced kidney injury, the nurse should
Correct Answer: B
Rationale: The correct answer is B because evaluating the patient's serum creatinine for up to 72 hours after the procedure is crucial in detecting contrast-induced kidney injury. An increase in serum creatinine levels indicates impaired kidney function due to the contrast dye. This monitoring allows for early detection and intervention to prevent further kidney damage. Choice A is incorrect because a decrease in urine output is a late sign of kidney injury and may not be present in the early stages. Choice C is incorrect as a renal ultrasound is not typically used to detect contrast-induced kidney injury. Choice D is incorrect as postvoid residual volume assessment is not specific to detecting intrarenal injury related to contrast dye use.
Question 3 of 9
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.
Question 4 of 9
Which statement about resuscitation is true?
Correct Answer: D
Rationale: The correct answer is D because it accurately states that withholding "extraordinary" resuscitation is legal and should be based on specified criteria in advance directives and physician orders. This is in line with medical ethics and patient autonomy. A is incorrect because family presence during resuscitation can be beneficial for emotional support and decision-making. B is incorrect as it is still necessary for a physician to document "do not resuscitate" orders even with a healthcare surrogate. C is incorrect as "slow codes" are not ethical and go against the principle of beneficence.
Question 5 of 9
The family of a critically ill patient has asked to discuss organ donation with the patient’s nurse. When preparing to answer the family’s questions, th e nurse understands which concern(s) most often influence a family’s decision to donate? (Select all that apply.)
Correct Answer: A
Rationale: Rationale for Correct Answer A: Donor disfigurement influences on funeral care. Families often consider the impact of organ donation on the appearance of their loved one during funeral arrangements. This concern can significantly influence their decision to donate. Incorrect Answers: B: Fear of inferior medical care provided to donor. This is not a common concern as medical care for donors is typically of high quality. C: Age and location of all possible organ recipients. While important, this is not a primary concern for families when deciding on organ donation. D: Concern that donated organs will not be used. Families are generally more concerned about the impact on their loved one's appearance post-donation rather than the utilization of organs.
Question 6 of 9
A nurse is on a committee that is trying to reduce the occurrence of hospital-acquired infections in the ICU. Her role is to conduct research to find which interventions have been shown to be most effective in reducing these infections. She consults many different sources and finds conflicting information. Which of the following sources should she consider the most authoritative?
Correct Answer: B
Rationale: The correct answer is B: A meta-analysis of randomized controlled trials in the American Journal of Nursing. 1. Meta-analyses provide a comprehensive overview of multiple studies, increasing the reliability of the findings. 2. Randomized controlled trials are considered the gold standard in research design for assessing intervention effectiveness. 3. The American Journal of Nursing is a reputable source in the field of nursing, ensuring the credibility of the study. 4. By synthesizing data from various trials, the meta-analysis can offer a more robust and generalizable conclusion compared to a single trial or qualitative studies. Incorrect choices: A: AACN expert panel report - Expert opinions may vary and lack the empirical evidence provided by research studies. C: A systematic review of qualitative studies in the Journal of Advanced Nursing - Qualitative studies may provide valuable insights but may not offer concrete evidence on intervention effectiveness like quantitative studies. D: A single randomized controlled trial in the American Journal of Critical Care - Single trials may not capture the full picture and
Question 7 of 9
Which action is best for the nurse to take to ensure culturally competent care for an alert, terminally ill Filipino patient?
Correct Answer: A
Rationale: The correct answer is A because it promotes patient-centered care by involving the patient and family in decision-making, respecting their autonomy and preferences. This approach acknowledges the importance of cultural beliefs and values in end-of-life care. Choice B undermines patient autonomy by bypassing direct communication with the patient. Choice C assumes all Filipino individuals have the same cultural needs, which is not accurate. Choice D generalizes preferences without considering individual patient needs and wishes. Overall, choice A is the most appropriate as it aligns with the principles of patient-centered care and cultural competence.
Question 8 of 9
A triage nurse in a busy emergency department (ED) assesses a patient who complains of 7/10 abdominal pain and states, 'I had a temperature of 103.9°F (39.9°C) at home.' The nurse’s first action should be to:
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.
Question 9 of 9
The VALUE mnemonic is a helpful strategy to enhance communication with family members of critically ill patients. Which of the following statements describes a VALUE strategy?
Correct Answer: B
Rationale: The correct answer is B: Acknowledge family emotions. This is a key component of the VALUE strategy as it emphasizes empathy and understanding towards the emotions that family members may be experiencing during a difficult time. By acknowledging their emotions, healthcare providers can build trust and establish a supportive relationship with the family. Choice A is incorrect because the VALUE strategy focuses on treating family members as integral members of the care team, not just as guests. Choice C is incorrect as learning about family structure and function is important but not specifically part of the VALUE strategy. Choice D is incorrect as using a trained interpreter is important for effective communication but is not specific to the VALUE mnemonic.
