Critical Care Nursing Questions and Answers PDF Questions
Question 1 of 5
When caring for a patient with a pulmonary artery (PA) pressure catheter, the nurse observes that the PA waveform indicates that the catheter is in the wedged position. Which action should the nurse take next?
Correct Answer: C
Rationale: The correct answer is C: Notify the health care provider. When the PA waveform indicates the catheter is in the wedged position, it means the catheter tip is in the pulmonary artery, potentially causing complications. The nurse should notify the healthcare provider immediately to assess and reposition the catheter to prevent further issues. Zero balancing the transducer (A) or activating the fast flush system (B) are not appropriate actions for this situation. Deflating and reinflating the PA balloon (D) could exacerbate the issue and should only be done under the guidance of the healthcare provider.
Question 2 of 5
After a change-of-shift report on a ventilator weaning unit, which patient should the nurse assess first?
Correct Answer: D
Rationale: The correct answer is D - Patient who was successfully weaned and extubated 4 hours ago and now has no urine output for the last 6 hours. This patient should be assessed first because the absence of urine output for 6 hours after being extubated could indicate acute kidney injury or other serious complications that need immediate attention. Urine output is a crucial indicator of renal function and can reflect the patient's overall hemodynamic status. In contrast, the other choices do not present immediate life-threatening conditions. Choice A involves a patient in rest mode post-failed breathing trial, which does not require immediate assessment. Choice B mentions continuous PETCO2 monitoring, which is important but not as urgent as assessing a patient with no urine output. Choice C describes a patient with a ScvO2 of 69%, which may need monitoring but does not indicate an urgent priority compared to assessing a patient with no urine output after recent extubation.
Question 3 of 5
After the return of spontaneous circulation following the resuscitation of a patient who had a cardiac arrest, therapeutic hypothermia is ordered. Which action will the nurse include in the plan of care?
Correct Answer: A
Rationale: The correct answer is A: Apply external cooling device. Therapeutic hypothermia is a treatment used to protect the brain after cardiac arrest by lowering the body temperature. The nurse should use external cooling devices, such as cooling blankets or ice packs, to achieve and maintain the desired temperature. This method allows for precise temperature control and monitoring. Checking mental status every 15 minutes (choice B) is not the priority as maintaining the temperature is crucial. Avoiding sedative medications (choice C) may be necessary to accurately assess the patient's neurological status. Rewarming if the temperature is <91°F (32.8°C) (choice D) is incorrect as the goal is to maintain hypothermia for a specific duration before gradual rewarming.
Question 4 of 5
When planning the response to the potential use of smallpox as an agent of terrorism, the emergency department (ED) nurse manager will plan to obtain adequate quantities of:
Correct Answer: A
Rationale: The correct answer is A: Vaccine. Smallpox is a contagious and potentially deadly disease caused by the variola virus. The smallpox vaccine is the most effective way to prevent and control the spread of smallpox. By obtaining adequate quantities of the smallpox vaccine, the ED nurse manager can protect healthcare workers and the public from contracting the virus in case of a smallpox bioterrorism event. Atropine (B) is used to treat certain types of nerve agent poisoning, not smallpox. Antibiotics (C) are ineffective against viruses like smallpox. Whole blood (D) is not specifically needed for smallpox treatment.
Question 5 of 5
The following interventions are part of the emergency department (ED) protocol for a patient who has been admitted with multiple bee stings to the hands. Which action should the nurse take first?
Correct Answer: A
Rationale: The correct answer is A: Remove the patient's rings first. This is crucial to prevent constriction and swelling due to potential allergic reactions or inflammation from bee stings. Removing rings allows for proper circulation and prevents complications like compartment syndrome. Ice packs (B) can be applied after removing the rings to reduce swelling. Calamine lotion (C) can provide relief for itching but is not as urgent as ring removal. Diphenhydramine (D) can be given later for systemic allergic reactions but should not take precedence over removing the rings.
