Critical Care Nursing Questions and Answers PDF

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.

Correct Answer: C

Rationale: The correct answer is C: A persistent vegetative state. This choice is correct because the patient exhibits minimal responsiveness, only withdrawing to painful stimuli, and lacks meaningful interaction or consciousness. A persistent vegetative state is characterized by preserved wakefulness without awareness, which aligns with the patient's condition. Choice A: An organ donor is incorrect because the patient's neurological impairment does not necessarily indicate readiness for organ donation. Choice B: Brain death is incorrect because the patient still exhibits some reflexive responses, indicating a level of brain function beyond brain death. Choice D: Terminally ill is incorrect as it does not specifically address the patient's neurological status and prognosis, which is better described by a persistent vegetative state.

Correct Answer: C

Rationale: The most appropriate nursing action in this scenario is choice C: Provide support for the patient�s decision and ensure comfort measures. This is because the patient is in hospice care, indicating a focus on comfort and quality of life rather than aggressive treatments. By respecting the patient�s decision and providing comfort measures, the nurse promotes dignity and autonomy. Choices A and B are not suitable as they go against the patient's wishes and may cause distress. Choice D, while important, is not the immediate priority when the patient is not in pain and has chosen to refuse food and fluids. Overall, choice C aligns with the principles of hospice care and prioritizes the patient's comfort and autonomy.

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.

Correct Answer: B

Rationale: The correct answer is B: Ensure that a sterile field is maintained during the insertion procedure. This is the priority nursing action because maintaining a sterile field is crucial to prevent infection during the invasive procedure. The nurse must follow strict aseptic technique to reduce the risk of introducing bacteria into the patient's bloodstream. All other choices are incorrect: A: Addressing the patient's anxiety is important but not the priority during the insertion procedure. C: Inflating the balloon is a specific action that should be performed by the physician, not the nurse. D: While monitoring the patient's cardiac rhythm is important, ensuring the sterile field takes precedence to prevent complications.
