Critical Care Nursing Questions Questions
Question 1 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 2 of 5
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 3 of 5
The nurse is caring for an elderly patient who was admitted with renal insufficiency. An expected laboratory finding for this patient may be
Correct Answer: B
Rationale: The correct answer is B: a normal serum creatinine level. In renal insufficiency, the kidneys are not able to filter waste products effectively, leading to an increase in serum creatinine levels. This is a common indicator of renal dysfunction. A: An increased GFR would not be expected in renal insufficiency, as it signifies improved kidney function. C: Increased ability to excrete drugs is not a typical finding in renal insufficiency, as impaired kidney function can lead to drug accumulation. D: Hypokalemia is not directly related to renal insufficiency. It is more commonly associated with factors like diuretic use or gastrointestinal losses.
Question 4 of 5
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 5 of 5
When caring for a patient who has an arterial catheter in the left radial artery for arterial pressure-based cardiac output (APCO) monitoring, which information obtained by the nurse is most important to report to the health care provider?
Correct Answer: B
Rationale: The correct answer is B: There is redness at the catheter insertion site. Redness at the catheter insertion site could indicate infection, which is a serious complication that requires immediate attention to prevent sepsis. Reporting this to the healthcare provider promptly is crucial for timely intervention. Choices A, C, and D are not as urgent. A positive Allen test (choice A) assesses collateral circulation and is important for assessing perfusion before arterial cannulation but does not require immediate intervention. Choice C (MAP is 86 mm Hg) falls within the normal range, so it does not indicate an urgent issue. The visibility of the dicrotic notch in the arterial waveform (choice D) is a normal finding and does not require immediate action.
