Critical Care Nursing Questions and Answers PDF

Correct Answer: C

Rationale: The correct answer is C: Tachycardia. Hypoxemia results in decreased oxygen levels in the blood, stimulating the body to increase heart rate to improve oxygen delivery. Tachycardia is an early sign of the cardiovascular system compensating for hypoxemia. Heart block (A) is a disruption in the electrical conduction within the heart and is not directly related to hypoxemia. Restlessness (B) is a non-specific sign and can be caused by various factors. Tachypnea (D) is an increased respiratory rate, which is a response to hypoxemia but not a direct effect on the cardiovascular system.

Correct Answer: D

Rationale: The correct answer is D: Deal with issues and not personalities. This guideline is important because it focuses on resolving the conflict based on the actual problem at hand, rather than personal biases or emotions. By addressing the issues causing the argument, the nurse can help the UAPs find a fair and logical solution. A: Requiring the UAPs to reach a compromise may not address the root cause of the conflict and could lead to further disagreements. B: Weighing the consequences is important but may not be as effective in resolving the conflict as directly addressing the issues. C: Encouraging humor may temporarily diffuse the situation but may not lead to a lasting resolution.

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 correct answer is C: Assessment. In the SBAR communication model, the nurse's information about the patient's history and vital signs falls under the Assessment component. This is because the nurse is providing a detailed evaluation of the patient's current condition based on objective data such as urine output, heart rate, blood pressure, and other key indicators. The nurse is analyzing the situation and forming a judgment that the patient is hypovolemic, indicating a fluid deficit. This assessment is crucial for informing further actions or interventions, such as increasing fluids or providing a fluid challenge. Summary of other choices: A: Situation - This choice would refer to a brief summary of the current situation without detailed analysis or interpretation. B: Background - This choice would involve providing relevant background information about the patient, such as medical history or recent procedures, but not the current assessment of the patient's condition. D: Recommendation - This choice would involve suggesting a course of action or treatment based on the assessment, which comes after

Correct Answer: A

Rationale: The correct answer is A, absence of a corneal reflex, because in brain death, all brainstem reflexes, including the corneal reflex, are absent. This indicates complete loss of brain function. Choice B, unequal reactive pupils, is incorrect as it suggests some level of brainstem function. Choice C, withdrawal from painful stimuli, is also incorrect as it is a spinal reflex and can occur even in the absence of brain function. Choice D, core temperature of 100.8� F, is irrelevant to assessing brain death.
