Critical Care Nursing Practice Questions Questions

Question 1 of 5

Both the electroencephalogram (EEG) monitor and the Bis pectral Index Score (BIS) or Patient State Index (PSI) analyzer monitors are used to ass ess patient sedation levels in critically ill patients. Why are the BIS and PSI monitors simpler to use?

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.

Question 2 of 5

The nurse is caring for a patient diagnosed with hyperactivaebi rdb.ecloimri/tuemst . The nurse focuses interventions toward which priority need?

Correct Answer: C

Rationale: The correct answer is C: Safety. In hyperactive delirium, the patient may be agitated, disoriented, and at risk of harm. Safety is the priority to prevent falls or injury. Comfort (A) is important but secondary to safety in this case. Nourishment (B) can wait until safety is ensured. Sedation (D) may be considered but only after safety measures are in place.

Question 3 of 5

While family members are visiting, a patient has a respiratory arrest and is being resuscitated. Which action by the nurse is best?

Correct Answer: A

Rationale: The correct answer is A because it respects the patient's right to privacy while also acknowledging the family's presence. By asking family members if they wish to remain in the room, the nurse allows them to make an informed decision based on their comfort level. This approach fosters open communication and shows respect for the family's emotions. Choice B is incorrect because abruptly removing family members can increase their distress and feelings of powerlessness. Choice C is incorrect as it places the burden of support solely on a staff member, potentially isolating the family from the situation. Choice D is incorrect as it assumes family members should stay without considering their preferences or emotional well-being.

Question 4 of 5

The nurse is caring for a patient with an arterial monitoring system. The nurse assesses the patient�s noninvasive cuff blood pressure to be 70/40 mm Hg. The arterial blood pressure measurement via an intraarterial catheter in the same arm is assessed by the nurse to be 108/70 mm Hg. What is the best action by the nurse?

Correct Answer: C

Rationale: Rationale for Correct Answer (C - Assess the cuff for proper arm size): 1. The cuff blood pressure (70/40 mm Hg) is significantly lower than the arterial blood pressure (108/70 mm Hg). 2. Discrepancy suggests cuff size mismatch, leading to inaccurate readings. 3. Assessing cuff size ensures accurate blood pressure measurement. 4. Ensures appropriate interventions based on accurate readings. Summary of Incorrect Choices: A: Rapid response not warranted based solely on blood pressure discrepancy. B: Trendelenburg position not indicated for cuff size issue. D: Normal saline bolus not appropriate without accurate blood pressure measurement.

Question 5 of 5

An 81-year-old patient who has been in the intensive care unit (ICU) for a week is now stable, and transfer to the progressive care unit is planned. On rounds, the nurse notices that the patient has new onset confusion. The nurse will plan to:

Correct Answer: C

Rationale: The correct answer is C: Notify the health care provider and postpone the transfer. The new onset confusion in an elderly patient in the ICU can be a sign of delirium, which is a serious condition that requires prompt evaluation and management. By notifying the healthcare provider, they can assess the patient's condition, order appropriate tests, and adjust the treatment plan as needed. Postponing the transfer allows for further observation and intervention to address the underlying cause of the confusion. Choice A (Give PRN lorazepam and cancel the transfer) is incorrect because administering lorazepam may worsen the confusion in an elderly patient and should not be done without proper evaluation. Choice B (Inform the receiving nurse and then transfer the patient) is incorrect because transferring the patient without addressing the new onset confusion can lead to potential complications and delay in appropriate management. Choice D (Obtain an order for restraints as needed and transfer the patient) is incorrect because using restraints should only be considered as a
