To prevent any unwanted resuscitation after life-sustaininga btirrbe.acotmm/teenstt s have been withdrawn, the nurse should ensure that what intervention has been im plemented?
- A. Do-not-resuscitate (DNR) orders are written before dis continuation of the treatments.
- B. The family is not allowed to visit until the death occur s.
- C. DNR orders are written as soon as possible after the di scontinuation of the treatments.
- D. The change-of-shift report includes the information thaatb irtbh.ceo pma/tetiset nt is not to be resuscitated.
Correct Answer: A
Rationale: The correct answer is A because writing DNR orders before discontinuation of life-sustaining treatments ensures clear communication and legal documentation of the patient's wishes. Choice B is incorrect as family support is essential in end-of-life care. Choice C is incorrect as DNR orders should be established before withdrawing treatment. Choice D is incorrect as the DNR order should be in place before shift change for immediate implementation if needed.

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 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.
The term used to describe an increase in blood urea nitrogen (BUN) and serum creatinine is
- A. oliguria.
- B. azotemia.
- C. acute kidney injury.
- D. prerenal disease.
Correct Answer: B
Rationale: The correct answer is B: azotemia. Azotemia refers to an increase in BUN and serum creatinine levels, indicating impaired kidney function. Oliguria (A) is a decrease in urine output, not specific to BUN and creatinine levels. Acute kidney injury (C) is a broader term encompassing various causes of kidney dysfunction, not specific to elevated BUN and creatinine. Prerenal disease (D) refers to conditions affecting blood flow to the kidneys, not directly related to elevated BUN and creatinine levels.
During the primary survey of a patient with severe leg trauma, the nurse observes that the patient’s left pedal pulse is absent and the leg is swollen. Which action will the nurse take next?
- A. Send blood to the lab for a complete blood count.
- B. Assess further for a cause of the decreased circulation.
- C. Finish the airway, breathing, circulation, and disability survey.
- D. Start normal saline fluid infusion with a large-bore IV line.
Correct Answer: B
Rationale: The correct answer is B: Assess further for a cause of the decreased circulation. The nurse should prioritize assessing the cause of the absent left pedal pulse and leg swelling to address the severe leg trauma effectively. This step involves identifying potential vascular compromise or compartment syndrome, which are critical conditions requiring immediate intervention. Sending blood for a complete blood count (A) is not the priority in this situation. Finishing the primary survey (C) may delay addressing the circulation issue. Starting normal saline infusion (D) without addressing the circulation problem first could potentially worsen the condition. Therefore, assessing further for the cause of decreased circulation is the most appropriate next step to ensure timely and appropriate management of the patient's condition.
The transplant clinic coordinator is evaluating relatives of a patient with end-stage renal disease, whose blood type is A positive, for suitability as aa bliirvb.icnogm /dteostn or for kidney transplantation. Which family member best qualifies for evaluation?
- A. A 65-year-old brother with a history of hypertension; b lood type A positive
- B. A 35-year-old female with a history of food allergies; blood type O negative
- C. A 14-year-old son, otherwise healthy with no history; blood type B negative
- D. A 70-year-old mother, with a history of sinus infection s; blood type A positive
Correct Answer: D
Rationale: The correct answer is D, the 70-year-old mother with blood type A positive. This choice is the best candidate for evaluation due to her blood type matching the patient's (A positive) for kidney transplantation. Age and medical history are also crucial factors in determining suitability. The 65-year-old brother (choice A) has hypertension, a significant risk factor. The 35-year-old female (choice B) with food allergies may have potential complications. The 14-year-old son (choice C) is underage and might not be a suitable donor due to age and the potential impact on his growth and development. In summary, choice D aligns with the matching blood type and age, making the mother the most suitable candidate for evaluation.
