Critical Care Nursing Exam Questions Questions
Question 1 of 9
The patient is in a progressive care unit following arteriovenous fistula implantation in his left upper arm, and is due to have blood drawn with his next set of vital signs and assessment. When the nurse assesses the patient, the nurse should
Correct Answer: D
Rationale: The correct answer is D because after arteriovenous fistula implantation, it is essential to assess for the presence of a bruit (audible sound caused by turbulent blood flow) and thrill (vibratory sensation) in the access site, which indicates proper functioning of the fistula. This assessment ensures that blood is flowing adequately through the newly created access for dialysis or other procedures. Drawing blood or taking blood pressures from the fistula arm can lead to complications such as clot formation or damage to the fistula. Starting a new IV line in the same arm is contraindicated to avoid compromising the newly created fistula. Thus, auscultating for a bruit and palpating for a thrill are the appropriate nursing actions in this scenario.
Question 2 of 9
Which statement is a likely response from someone who h as survived a stay in the critical care unit?
Correct Answer: A
Rationale: Rationale: Choice A is the correct answer because it reflects a positive attitude towards potential future treatments in the critical care unit and gratitude for being able to see family again. The survivor acknowledges the past experience but remains optimistic. Summary: - Choice B is incorrect as it shows a strong aversion to hospital care, indicating a preference for death over treatment. - Choice C is incorrect as it focuses on the family's reaction and not the survivor's personal experience or perspective. - Choice D is incorrect as it highlights a trivial aspect (eating) rather than reflecting on the ICU experience or future treatments.
Question 3 of 9
A nurse who works in an intermediate care unit has experienced high nursing turnover. The nurse manager is often considered to be an autocratic leade r by staff members and that leadership style is contributing to turnover. The nurse asks to be involved in developing new guidelines to prevent pressure ulcers in the patient populat ion. The nurse manager suggests that the nurse has not yet had enough experience to be on tahbierb p.croemv/teenstt ion task force. This situation and setting is an example of what form of ineffec tive leadership?
Correct Answer: C
Rationale: The correct answer is C: Displaying ineffective decision making. In this scenario, the nurse manager's decision to exclude the nurse from participating in developing new guidelines is an example of ineffective decision making. By dismissing the nurse's request based on lack of experience rather than considering their input and involvement, the manager is not utilizing the nurse's expertise and potentially missing out on valuable insights. This decision reflects a lack of inclusivity, collaboration, and respect for the nurse's professional growth and potential contributions. The other choices are not directly applicable in this context as the core issue lies in the manager's decision-making process.
Question 4 of 9
Intrapulmonary shunting refers to what outcome?
Correct Answer: C
Rationale: Step-by-step rationale for why choice C is correct: 1. Intrapulmonary shunting refers to blood bypassing the normal oxygenation process in the lungs. 2. Choice C describes blood being shunted from the right side of the heart (deoxygenated blood) to the left side without oxygenation, leading to systemic circulation without oxygenation. 3. Choices A, B, and D do not accurately describe intrapulmonary shunting as they focus on other concepts like alveolar perfusion, heart failure, and unilateral lung blood supply, respectively.
Question 5 of 9
A nurse who has been recently hired to manage the nursing staff of the ICU is concerned at the lack of evidence-based practice she sees among the staff. Which of the following would be the best step for her to take to promote incorporating evidence into clinical practice?
Correct Answer: D
Rationale: The correct answer is D because introducing the staff to the PubMed search engine and assigning them topics to research on it is the most effective way to promote evidence-based practice. PubMed is a reputable database that contains a vast collection of peer-reviewed articles and research studies, making it a reliable source for evidence. By assigning specific topics, the nurse can ensure that the staff is focusing on relevant and current information, fostering a deeper understanding of evidence-based practice. Choice A is incorrect because certification in critical care nursing does not guarantee a commitment to evidence-based practice. Choice B is not as effective as it relies on passive exposure to journals rather than active engagement with specific research topics. Choice C is not the best option as using general search terms on search engines like Google or Yahoo may lead to unreliable or outdated information.
Question 6 of 9
The nurse caring for a patient with an endotracheal tube un derstands that endotracheal suctioning is needed to facilitate removal of secretions. What additional information is the nurse aware of concerning this intervention?
Correct Answer: C
Rationale: Rationale for Correct Answer C: Endotracheal suctioning should be done as indicated by patient assessment because not all patients require routine suctioning. Performing unnecessary suctioning can lead to potential complications such as mucosal damage and increased risk of infection. Therefore, the nurse must assess the patient's respiratory status, auscultate lung sounds, monitor oxygen saturation levels, and observe for signs of increased secretions before deciding to perform suctioning. Summary of Incorrect Choices: A: Endotracheal suctioning does not directly impact intracranial pressure. It is primarily focused on maintaining airway patency and removing respiratory secretions. B: While endotracheal suctioning may temporarily suppress the cough reflex during the procedure, its primary purpose is to clear airway secretions to prevent complications such as atelectasis and respiratory distress. D: Saline instillation before suctioning is not recommended as it can lead to negative outcomes such as dehydration, mucosal damage, and increased risk of infection
Question 7 of 9
The nurse is caring for a patient whose ventilator settings i nclude 15 cm H O of positive end-expiratory pressure (PEEP). The nurse understands that although beneficial, PEEP may result in what possible problem?
Correct Answer: D
Rationale: Rationale for Correct Answer (D - Low cardiac output secondary to increased intrathoracic pressure): 1. PEEP increases intrathoracic pressure, which can impede venous return to the heart. 2. Impaired venous return reduces preload, leading to decreased cardiac output. 3. Decreased cardiac output can result in inadequate tissue perfusion and oxygenation. 4. Therefore, PEEP may cause low cardiac output due to increased intrathoracic pressure. Summary of Incorrect Choices: A. Fluid overload is not directly related to PEEP but more to fluid administration or kidney function. B. High cardiac index is unlikely as PEEP can decrease cardiac output. C. Hypoxemia is not a direct result of PEEP but may occur due to other factors like inadequate ventilation or oxygenation settings.
Question 8 of 9
A critically ill patient who is intubated and agitated is restrained with soft wrist restraints. Based on research findings, what is the best nursing action?
Correct Answer: D
Rationale: The correct answer is D: Assess and intervene for causes of agitation. In a critically ill patient, agitation while intubated could indicate underlying issues like pain, delirium, or inadequate sedation. By assessing and addressing the root cause of agitation, the nurse can improve patient comfort and prevent potential harm from restraints. Removing restraints periodically for skin integrity (B) and range of motion (C) is important but should not be the primary focus when agitation is present. Maintaining restraints (A) without addressing the agitation could lead to increased distress and potential complications.
Question 9 of 9
An Ethiopian man with AIDS has recently been admitted to the ICU with a case of pneumonia. The man is new to the U.S. and has no health insurance. He would likely be eligible for the states Medicaid coverage, but does not understand how to access this coverage. Which competency or competencies are most needed in this situation? Select all that apply.
Correct Answer: B
Rationale: The correct answer is B: Advocacy and moral agency. In this scenario, the Ethiopian man with AIDS is in a vulnerable position due to lack of health insurance and understanding of Medicaid coverage. Advocacy skills are crucial to help him navigate the complex healthcare system and access the necessary resources. Moral agency involves advocating for the patient's rights and well-being, ensuring that he receives appropriate care despite his socioeconomic status. Clinical judgment, collaboration, and systems thinking are important competencies but not as directly relevant in this specific situation of advocating for the patient's access to Medicaid coverage.
