The nurse is concerned about the risk of alcohol withdraw al syndrome in a 45-year-old postoperative patient. Which statement indicates an unders tanding of management of this patient?
- A. “Alcohol withdrawal is common; we see it all of the tiambierb .icno mth/tees tt rauma unit.”
- B. “There is no way to assess for alcohol withdrawal.”
- C. “This patient will require less pain medication.”
- D. “We have initiated the alcohol withdrawal protocol.”
Correct Answer: D
Rationale: The correct answer is D because initiating the alcohol withdrawal protocol shows an understanding of managing a patient at risk for alcohol withdrawal syndrome. This protocol involves carefully monitoring the patient's symptoms, providing appropriate medications, and ensuring a safe environment. Option A is incorrect as it downplays the seriousness of alcohol withdrawal. Option B is incorrect as there are assessment tools available for identifying alcohol withdrawal. Option C is incorrect as pain management should be tailored to the individual's needs, not necessarily lessened due to alcohol withdrawal risk.

The critical care environment is stressful to the patient. Which interventions assist in reducing this stress? (Select all that apply.)
- A. Adjust lighting to promote normal sleep-wake cycles.
- B. Provide clocks, calendars, and personal photos in the p atient’s room.
- C. Talk to the patient about other patients you are caring for on the unit.
- D. Tell the patient the day and time when you are providi ng routine nursing interventions.
Correct Answer: A
Rationale: Correct Answer: A. Adjust lighting to promote normal sleep-wake cycles.
Rationale:
1. Adjusting lighting can help regulate the patient's circadian rhythm, promoting better sleep and reducing stress.
2. Normal sleep-wake cycles are crucial for overall well-being and healing in a critical care setting.
3. Proper lighting can also create a more calming environment for the patient.
Summary of Incorrect Choices:
B. Providing clocks, calendars, and personal photos can be overwhelming for a stressed patient.
C. Talking about other patients may increase anxiety and breach patient confidentiality.
D. Telling the day and time of routine interventions may disrupt the patient's sense of time and add to stress.
A 68-year-old patient has been in the intensive care unit for 4 days and has a nursing diagnosis of disturbed sensory perception related to sleep deprivation. Which action should the nurse include in the plan of care?
- A. Administer prescribed sedatives or opioids at bedtime to promote sleep.
- B. Cluster nursing activities so that the patient has uninterrupted rest periods.
- C. Silence the alarms on the cardiac monitors to allow 30- to 40-minute naps.
- D. Eliminate assessments between 0100 and 0600 to allow uninterrupted sleep.
Correct Answer: B
Rationale: The correct answer is B: Cluster nursing activities so that the patient has uninterrupted rest periods.
Rationale:
1. Clustering nursing activities allows for uninterrupted rest periods, essential for improving sleep quality and addressing disturbed sensory perception.
2. Administering sedatives or opioids (Option A) can lead to drug dependence, tolerance, and adverse effects in older adults.
3. Silencing alarms (Option C) compromises patient safety by impeding timely monitoring and response to critical events.
4. Eliminating assessments (Option D) between 0100 and 0600 disregards the necessity of monitoring vital signs and assessing patient condition around the clock.
Continuous venovenous hemodialysis is used to
- A. remove fluids and solutes through the process of convection.
- B. remove plasma water in cases of volume overload.
- C. remove plasma water and solutes by adding dialysate.
- D. combine ultrafiltration, convection and dialysis
Correct Answer: D
Rationale: The correct answer is D because continuous venovenous hemodialysis combines ultrafiltration, convection, and dialysis techniques. Ultrafiltration removes excess fluid, convection helps in removing solutes, and dialysis involves the diffusion of solutes across a semipermeable membrane. This comprehensive approach ensures effective removal of both fluid and solutes in critically ill patients.
Incorrect Answer Analysis:
A: Removing fluids and solutes through convection alone is not the complete process in continuous venovenous hemodialysis.
B: While volume overload is addressed, continuous venovenous hemodialysis involves more than just removing plasma water.
C: Adding dialysate is not the primary method in continuous venovenous hemodialysis; it involves ultrafiltration, convection, and dialysis techniques.
The nurse is using presence to reduce the anxiety of a critically ill patient. What nursing behavior demonstrates an effective use of presence?
- A. Staying in the patients room to complete documentation
- B. Having a conversation in the patients room that excludes the patient
- C. Maintaining eye contact with the patient during explanations
- D. Focusing on specific nursing care tasks while in the patients room
Correct Answer: C
Rationale: The correct answer is C because maintaining eye contact with the patient during explanations is a non-verbal way to show attentiveness and empathy, which can help reduce the patient's anxiety. This behavior demonstrates active listening and engagement, making the patient feel heard and understood.
A: Staying in the patient's room to complete documentation is not an effective use of presence as it does not involve direct interaction with the patient.
B: Having a conversation in the patient's room that excludes the patient is also not an effective use of presence as it does not involve engaging with the patient.
D: Focusing on specific nursing care tasks while in the patient's room, although important, may not necessarily demonstrate presence in reducing the patient's anxiety.
The nurse calculates the PaO /FiO ratio for the following values: PaO is 78 mm Hg; FiO is 2 2 2 2 6 (60%). What is the outcome and the relationship to the ARDS diagnosing criteria?
- A. 46.8; meets criteria for ARDS
- B. 130; meets criteria for ARDS
- C. 468; normal lung function
- D. Not enough data to compute the ratio
Correct Answer: A
Rationale: The correct answer is A: 46.8; meets criteria for ARDS. The PaO /FiO ratio is calculated by dividing the arterial oxygen partial pressure (PaO) by the fraction of inspired oxygen (FiO). In this case, PaO is 78 mm Hg and FiO is 0.6 (60%). Therefore, the calculation would be 78/0.6 = 130. This value is less than 300, which is indicative of ARDS according to the Berlin criteria. Choices B and C are incorrect as they do not align with the criteria for ARDS. Choice D is incorrect because the data provided is sufficient to compute the ratio.
