Critical Care Nursing Practice Questions

Correct Answer: C

Rationale: The correct answer is C because a pulmonary artery occlusion pressure of 25 mm Hg indicates possible fluid overload or cardiac issue requiring urgent evaluation. This value is high, suggesting increased pressure in the left side of the heart. Additionally, the oxygen saturation of 89% on 3 L of oxygen indicates potential respiratory compromise. This patient needs immediate assessment and intervention to prevent worsening of their condition. Choice A is incorrect as a central venous pressure of 6 mm Hg is within normal limits, and the urine output is adequate. Choice B is incorrect as a BP of 110/60 mm Hg is acceptable, and a slightly dampened arterial waveform is not an immediate concern. Choice D is incorrect as a pulmonary artery pressure of 25/10 mm Hg is within normal range, and an oxygen saturation of 94% on 2 L of oxygen is acceptable.

Correct Answer: C

Rationale: Step 1: Comfort care is focused on providing relief from suffering and improving quality of life. Step 2: Patient-centered care emphasizes the individual's preferences and values. Step 3: Patient autonomy is a fundamental principle in healthcare decision-making. Step 4: Patients have the right to determine what constitutes comfort care for themselves. Step 5: Therefore, statement C is correct as it aligns with the patient's autonomy and individualized care approach. Summary: - Choice A is incorrect because legal distinctions between withholding and withdrawing treatment may vary. - Choice B is incorrect as it focuses on evaluating procedures rather than the patient's preferences. - Choice D is incorrect as withdrawing life-sustaining treatments is not universally considered euthanasia.

Correct Answer: A

Rationale: Rationale: The correct answer is A: A card from the girl's family. The nurse would value this form of recognition the most because it directly reflects the impact of her care on the patient and her family. It is a personal, heartfelt gesture that acknowledges the nurse's compassion and dedication. A card from the family shows genuine appreciation and gratitude for the nurse's efforts, making it the most meaningful form of recognition. Summary: - Choice B: A plaque from the ICU physicians could be seen as a formal recognition but lacks the personal touch and direct impact of the nurse's care on the patient and family. - Choice C: A letter of commendation from the hospital's administration is a professional acknowledgment but may not capture the emotional connection and impact that the nurse had on the family. - Choice D: A bouquet of flowers from her supervisor is a nice gesture but does not necessarily reflect the specific impact of the nurse's care on the patient and family.

Correct Answer: C

Rationale: The correct answer is C because BIS and PSI monitors provide both raw EEG data and a numeric value, simplifying the interpretation of patient sedation levels. Raw EEG data offers detailed information on brain activity, while the numeric value allows for quick assessment. This simplifies the monitoring process compared to interpreting raw EEG data alone. Choice A is incorrect as BIS and PSI monitors are not restricted to heavily sedated patients. Choice B is incorrect as they are not limited to pediatric patients. Choice D is incorrect as the number of leads required does not determine the simplicity of use; it is the data interpretation that matters.

Correct Answer: C

Rationale: The correct answer is C because maintaining hydration and nutrition until the patient dies is not always appropriate in end-of-life care, as some patients may be unable to tolerate oral intake or may be close to the end of life where artificial nutrition and hydration may not provide benefit and may even cause discomfort. Explanation: A: A is correct because terminally ill patients may indeed benefit from continuous pain management to ensure comfort. B: B is correct because hospice care is typically initiated when curative treatment is no longer effective and focuses on providing comfort and quality of life. D: D is correct because emotional support is crucial in end-of-life care to address the patient's psychological well-being and provide comfort. In summary, choice C is incorrect as it does not consider individual patient needs and preferences in end-of-life care.
