Critical Care Nursing Questions Questions
Question 1 of 5
Which assessment finding obtained by the nurse when caring for a patient with a right radial arterial line indicates a need for the nurse to take immediate action?
Correct Answer: A
Rationale: The correct answer is A because a cooler right hand may indicate compromised circulation, potentially due to arterial occlusion or clot formation. This could lead to inadequate perfusion and tissue damage. Immediate action is needed to assess and address the cause. Choice B is incorrect because a MAP of 77 mm Hg is within the normal range for most patients and does not require immediate action. Choice C is incorrect as delivering 3 mL of flush solution per hour is an appropriate rate and does not indicate a need for immediate action. Choice D is incorrect as the flush bag and tubing being changed 3 days ago does not necessarily indicate an immediate issue with the arterial line function.
Question 2 of 5
A nurse is weaning a 68-kg male patient who has chronic obstructive pulmonary disease (COPD) from mechanical ventilation. Which patient assessment finding indicates that the weaning protocol should be stopped?
Correct Answer: C
Rationale: The correct answer is C because a respiratory rate of 32 breaths/min indicates increased work of breathing, which could be a sign of respiratory distress. In a patient being weaned from mechanical ventilation, an elevated respiratory rate suggests that the patient may not be able to sustain adequate ventilation on their own. This warrants stopping the weaning protocol to prevent respiratory failure. Choice A is incorrect because a heart rate of 97 beats/min is within normal range for an adult. Choice B is incorrect because an oxygen saturation of 93% is acceptable for a patient with COPD. Choice D is incorrect because a tidal volume of 450 mL is adequate for a patient weaning from mechanical ventilation.
Question 3 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.
Question 4 of 5
The nurse is caring for a patient with a subarachnoid hemorrhage who is intubated and placed on a mechanical ventilator with 10 cm H2O of peak end-expiratory pressure (PEEP). When monitoring the patient, the nurse will need to notify the healthcare provider immediately if the patient develops:
Correct Answer: D
Rationale: The correct answer is D: Increased jugular venous distention. In a patient with a subarachnoid hemorrhage and on mechanical ventilation, increased jugular venous distention can indicate increased intracranial pressure, which can be life-threatening. The nurse should notify the healthcare provider immediately as it may require urgent intervention to prevent further neurological deterioration. A: Oxygen saturation of 93% is within the acceptable range for a patient on mechanical ventilation and may not require immediate notification. B: Respirations of 20 breaths/minute are within normal limits for a ventilated patient and do not necessarily indicate a critical condition. C: Green nasogastric tube drainage may indicate the presence of bile and could be related to gastrointestinal issues, but it does not pose an immediate threat to the patient's neurological status.
Question 5 of 5
During the primary assessment of a victim of a motor vehicle collision, the nurse determines that the patient is breathing and has an unobstructed airway. Which action should the nurse take next?
Correct Answer: B
Rationale: Rationale: The correct action is to observe the patient's respiratory effort next. This step ensures that the patient's breathing remains stable and adequate. If respiratory effort is compromised, immediate intervention is required. Checking for bilateral pulses (A) is important but comes after ensuring respiratory status. Checking level of consciousness (C) is also crucial but not as immediate as monitoring breathing. Examining for external bleeding (D) is important but not the priority when airway and breathing are already determined to be clear.
