The nurse wishes to increase the use of evidence-based practice in the critical care unit where he works. What is a significant barrier to the implementation of evidence-based practice?
- A. Use of computerized records by the hospital
- B. Health Information Privacy and Portability Act (HIPPA)
- C. Lack of knowledge about literature searches
- D. Strong collaborative relationships in the work setting
Correct Answer: C
Rationale: Rationale:
The correct answer is C because lack of knowledge about literature searches hinders the ability to find and utilize evidence-based practice guidelines. Nurses need to be skilled in conducting literature searches to access relevant research. Choices A, B, and D are incorrect as they do not directly impede the implementation of evidence-based practice in the critical care unit.

A critically ill patient experiences stress and anxiety from many factors. Treatment of the patient focuses on reducing stressors and providing supportive care such as nutrition, oxygenation, pain management, control of anxiety, and specific care of the illness or injury. What is the best rationale for these interventions?
- A. Helps to support the patients immune system
- B. Part of good nursing care
- C. Mandated by hospital policy
- D. Reassures the patient and family
Correct Answer: A
Rationale: The correct answer is A: Helps to support the patient's immune system. Providing supportive care such as nutrition, oxygenation, pain management, and anxiety control can help reduce stress, which in turn supports the immune system. Stress weakens the immune system, making the patient more vulnerable to infections and complications. By addressing stress and anxiety through supportive care, the patient's immune system is better able to function optimally, aiding in the recovery process.
Choices B, C, and D are incorrect because:
B: Part of good nursing care - While supportive care is indeed part of good nursing care, the key rationale for these interventions in a critically ill patient is to support the immune system, not just to provide good nursing care.
C: Mandated by hospital policy - Hospital policies may dictate certain aspects of care, but the primary goal of these interventions is to support the patient's immune system, not just to comply with hospital policies.
D: Reassures the patient and family - While providing reass
The nurse caring for a patient with an endotracheal tube un derstands that endotracheal suctioning is needed to facilitate removal of secretions. What additional information is the nurse aware of concerning this intervention?
- A. It decreases intracranial pressure.
- B. It depresses the cough reflex.
- C. It is done as indicated by patient assessment.
- D. It is more effective if preceded by saline instillation to loosen secretions.
Correct Answer: C
Rationale: Rationale for Correct Answer C: Endotracheal suctioning should be done as indicated by patient assessment because not all patients require routine suctioning. Performing unnecessary suctioning can lead to potential complications such as mucosal damage and increased risk of infection. Therefore, the nurse must assess the patient's respiratory status, auscultate lung sounds, monitor oxygen saturation levels, and observe for signs of increased secretions before deciding to perform suctioning.
Summary of Incorrect Choices:
A: Endotracheal suctioning does not directly impact intracranial pressure. It is primarily focused on maintaining airway patency and removing respiratory secretions.
B: While endotracheal suctioning may temporarily suppress the cough reflex during the procedure, its primary purpose is to clear airway secretions to prevent complications such as atelectasis and respiratory distress.
D: Saline instillation before suctioning is not recommended as it can lead to negative outcomes such as dehydration, mucosal damage, and increased risk of infection
The patient is admitted with complaints of general malaise and fatigue, along with a decreased urinary output. The patient’s urinalysis shows coarse, muddy brown granular casts and hematuria. The nurse determines that the patient has:
- A. acute kidney injury from a prerenal condition.
- B. acute kidney injury from postrenal obstruction.
- C. intrarenal disease, probably acute tubular necrosis.
- D. a urinary tract infection.
Correct Answer: C
Rationale: The correct answer is C: intrarenal disease, probably acute tubular necrosis. The patient's symptoms of general malaise, fatigue, decreased urinary output, along with the presence of coarse, muddy brown granular casts and hematuria in the urinalysis indicate kidney damage. Acute tubular necrosis is a common cause of acute kidney injury characterized by damage to the renal tubules, leading to impaired kidney function. The presence of granular casts and hematuria suggests tubular injury and bleeding within the kidney. Choices A and B are incorrect as they refer to prerenal and postrenal causes of kidney injury, respectively, which do not align with the patient's symptoms and urinalysis findings. Choice D is incorrect as a urinary tract infection would typically present with different symptoms and urinalysis findings.
The nurse is caring for a patient who sustained a head injury and is unresponsive to painful stimuli. Which intervention is most appropriate while bathaibnirgb. ctohme/ tpesatt ient?
- A. Ask a family member to help you bathe the patient, and discuss the family structure with the family member during the procedure .
- B. Because the patient is unconscious, complete care as q uickly and quietly as possible.
- C. Inform the patient of the day and time, and what kind o f care you are providing.
- D. Turn the television on to the evening news so that you and the patient can be updated to current events.
Correct Answer: B
Rationale: The correct answer is B: Because the patient is unconscious, complete care as quickly and quietly as possible. This is the most appropriate intervention as it prioritizes the patient's comfort and minimizes unnecessary stimulation. Performing care quickly reduces the time the patient is exposed to potentially uncomfortable procedures. Being quiet also helps create a calming environment for the patient, which is important for someone who is unresponsive.
Explanation for other choices:
A: Asking a family member to help and discussing family structure is not appropriate as it can be intrusive and may not be relevant or beneficial to the patient's care.
C: Informing the patient of the day and time is unnecessary as the patient is unresponsive. Providing care is more crucial than updating the patient.
D: Turning on the television is inappropriate as it introduces unnecessary noise and distraction, which can be overwhelming for an unresponsive patient.
The client has been in the CCU for several weeks and has been very unstable. One family member stays at the bedside constantly and even naps in a bedside chair. The nurse understands that the family member is exhibiting which family member response to critical illness?
- A. Exhibiting extreme distrust of the health care team
- B. Seeking evidence for future legal or punitive action
- C. Trying to maintain a level of control over the situation
- D. Experiencing extreme fatigue from constant stress
Correct Answer: C
Rationale: The correct answer is C: Trying to maintain a level of control over the situation. The family member staying at the bedside constantly and even napping there is likely trying to cope with the stressful situation by maintaining a sense of control and connection to the patient. This behavior can be a way for the family member to feel more involved and helpful during a time of uncertainty and powerlessness. Choices A and B involve negative assumptions about the family member's intentions without evidence. Choice D may be a result of the family member's actions but does not address the underlying motivation for their behavior.
