Critical Care Nursing Exam Questions Questions
Question 1 of 9
Which acid-base disturbances commonly occurs with the hyperventilation and impaired gas exchange seen in severe exacerbation of asthma?
Correct Answer: D
Rationale: The correct answer is D: Respiratory alkalosis. Hyperventilation in severe asthma exacerbation leads to excessive removal of CO2, causing a decrease in carbonic acid levels, resulting in respiratory alkalosis. Metabolic acidosis (A) is not typically associated with hyperventilation. Metabolic alkalosis (B) is caused by excessive loss of acid or gain of bicarbonate, not by hyperventilation. Respiratory acidosis (C) is characterized by an increase in CO2 levels due to inadequate ventilation, which is the opposite of what occurs in severe asthma exacerbation.
Question 2 of 9
While caring for a critically ill patient, the nurse knows that fostering patient control over the environment is a method for stress reduction. What nursing intervention gives the patient the most environmental control while still adhering to best practice principles?
Correct Answer: A
Rationale: Step 1: Asking the patient whether he or she wants to get out of bed allows the patient to make a decision regarding their immediate environment, promoting autonomy and control. Step 2: This intervention respects the patient's preferences and fosters a sense of dignity and empowerment, reducing stress. Step 3: Best practice principles in nursing emphasize patient-centered care and promoting patient autonomy. Summary: Choice A is correct as it directly involves the patient in decision-making, enhancing their sense of control. Choices B, C, and D do not provide the same level of autonomy and control to the patient, making them less effective in reducing stress and promoting patient well-being.
Question 3 of 9
Which assessment would cue the nurse to the potential of aa bc iru bt .ce o mre /ts ep sti ratory distress syndrome (ARDS) in a patient admitted with respiratory distress?
Correct Answer: B
Rationale: The correct answer is B. Increased peak inspiratory pressure on the ventilator would cue the nurse to the potential of ARDS in a patient with respiratory distress. ARDS is characterized by severe respiratory failure with bilateral pulmonary infiltrates. An increase in peak inspiratory pressure on the ventilator indicates that the lungs are becoming stiffer, which is a common finding in ARDS due to increased inflammation and fluid accumulation in the alveoli. This finding alerts the nurse to the possibility of ARDS and the need for further assessment and intervention. Summary of other choices: A: Increased oxygen saturation via pulse oximetry is a nonspecific finding and may not specifically indicate ARDS. C: Normal chest radiograph with enlarged cardiac structures is more indicative of heart failure rather than ARDS. D: PaO2/FiO2 ratio > 300 is a criterion used to diagnose ARDS, but a value higher than 300 actually indicates mild ARDS, so it would not necessarily cue the nurse
Question 4 of 9
A patient who has been diagnosed with inoperable lung cancer and has a poor prognosis plans a trip across the country to settle some issues with their siblings. The nurse recognizes that the patient is manifesting which psychosocial response to death?
Correct Answer: C
Rationale: The correct answer is C: Anxiety about unfinished business. The patient's desire to settle issues with their siblings before death indicates a concern about unresolved matters. This response aligns with the concept of psychosocial responses to death, specifically the need for closure and resolution. Restlessness (choice A) may not necessarily indicate a specific focus on unfinished business. Yearning and protest (choice B) typically refer to the initial stages of grief, not specifically related to settling unresolved issues. Fear of the meaninglessness of one's life (choice D) is more existential and philosophical, whereas the patient's focus here is on addressing specific issues with their siblings.
Question 5 of 9
The nurse is assisting with endotracheal intubation and un derstands correct placement of the endotracheal tube in the trachea would be identified by which of the following? (Select all that apply.)
Correct Answer: B
Rationale: The correct answer is B: Equal bilateral breath sounds upon auscultation. This indicates proper placement of the endotracheal tube in the trachea, ensuring both lungs are being ventilated equally. Rationale: 1. Auscultation of air over the epigastrium (Choice A) is incorrect as it indicates esophageal intubation, not tracheal intubation. 2. Position above the carina verified by chest x-ray (Choice C) is incorrect as it does not confirm proper placement at the trachea. 3. Positive detection of carbon dioxide (CO2) (Choice D) is incorrect as it indicates the presence of exhaled CO2, but not necessarily proper placement in the trachea.
Question 6 of 9
During the primary survey of a patient with severe leg trauma, the nurse observes that the patient’s left pedal pulse is absent and the leg is swollen. Which action will the nurse take next?
Correct Answer: B
Rationale: The correct answer is B: Assess further for a cause of the decreased circulation. The nurse should prioritize assessing the cause of the absent left pedal pulse and leg swelling to address the severe leg trauma effectively. This step involves identifying potential vascular compromise or compartment syndrome, which are critical conditions requiring immediate intervention. Sending blood for a complete blood count (A) is not the priority in this situation. Finishing the primary survey (C) may delay addressing the circulation issue. Starting normal saline infusion (D) without addressing the circulation problem first could potentially worsen the condition. Therefore, assessing further for the cause of decreased circulation is the most appropriate next step to ensure timely and appropriate management of the patient's condition.
Question 7 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 8 of 9
The patient is on intake and output (I&O), as well as daily weights. The nurse notes that output is considerably less than intake over the last shift, and daily weight is 1 kg more than yesterday. The nurse should
Correct Answer: C
Rationale: First, the nurse should assess the patient's lungs to rule out any potential respiratory issues causing fluid retention. This is crucial as the patient has signs of fluid imbalance with decreased output and increased weight. Assessing the lungs can help identify conditions like heart failure or pneumonia that may contribute to these changes. Drawing a trough level (choice A) is not a priority as it doesn't address the immediate concern of fluid imbalance. Placing the patient on fluid restriction (choice B) should only be done after identifying the cause of the imbalance. Inserting an indwelling catheter (choice D) is not necessary at this point as the issue is related to fluid balance, not urinary elimination.
Question 9 of 9
The nurse is concerned that a patient is at increased risk of developing a pulmonary embolus and develops a plan of care for prevention to include whic h intervention?
Correct Answer: D
Rationale: The correct answer is D: Mobility. Maintaining mobility helps prevent blood stasis, a leading factor in the development of pulmonary embolism. Movement promotes circulation, reducing the risk of blood clots. A: Antiseptic oral care is important for oral hygiene but not directly related to preventing pulmonary embolism. B: Bed rest with head of bed elevated can actually increase the risk of clots due to immobility. C: Coughing and deep breathing are beneficial for preventing respiratory complications but do not address the underlying cause of pulmonary embolism.
