A nurse who has been recently hired to manage the nursing staff of the ICU is concerned at the lack of evidence-based practice she sees among the staff. Which of the following would be the best step for her to take to promote incorporating evidence into clinical practice?

  • A. Only hire nurses certified in critical care nursing.
  • B. Leave copies of several different nursing journals in the nurses lounge.
  • C. Demonstrate to the staff the best nursing-related search terms to use in Google orYahoo!
  • D. Introduce the staff to the PubMed search engine and assign them topics to researchon it.
Correct Answer: D

Rationale: The correct answer is D because introducing the staff to the PubMed search engine and assigning them topics to research on it is the most effective way to promote evidence-based practice. PubMed is a reputable database that contains a vast collection of peer-reviewed articles and research studies, making it a reliable source for evidence. By assigning specific topics, the nurse can ensure that the staff is focusing on relevant and current information, fostering a deeper understanding of evidence-based practice.

Choice A is incorrect because certification in critical care nursing does not guarantee a commitment to evidence-based practice. Choice B is not as effective as it relies on passive exposure to journals rather than active engagement with specific research topics. Choice C is not the best option as using general search terms on search engines like Google or Yahoo may lead to unreliable or outdated information.

What is an early signs of the effect of hypoxemia on the nervous system?

  • A. Cyanosis
  • B. Restlessness
  • C. Tachycardia
  • D. Tachypnea
Correct Answer: B

Rationale: The correct answer is B: Restlessness. When the body experiences hypoxemia (low oxygen levels), the brain is deprived of oxygen, leading to early signs such as restlessness. This is due to the brain's attempt to increase oxygen intake by increasing activity. Cyanosis (A) is a late sign of hypoxemia when oxygen levels are critically low. Tachycardia (C) and tachypnea (D) are compensatory mechanisms in response to hypoxemia, but they are not early signs affecting the nervous system directly.

What strategies are appropriate for preventing deep vein tharboirbm.cbomo/steisst (DVT) and pulmonary embolus (PE) in an at-risk patient? (Select all that apply.) WWW .THENURSINGMASTERY.COM

  • A. Graduated compression stockings
  • B. Heparin or low–molecular weight heparin
  • C. Sequential compression devices
  • D. Strict bed rest
Correct Answer: A

Rationale: The correct answer is A: Graduated compression stockings. These stockings help prevent blood from pooling in the legs, reducing the risk of DVT and PE. They improve circulation and reduce venous stasis. Option B, heparin, is used for treatment, not prevention. Option C, sequential compression devices, help prevent DVT but are not as effective as compression stockings. Option D, strict bed rest, can actually increase the risk of DVT by reducing blood flow.

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 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 22-year-old patient who experienced a near-drowning accident in a local pool, but now is awake and breathing spontaneously, is admitted for observation. Which assessment will be most important for the nurse to take during the observation period?

  • A. Auscultate heart sounds.
  • B. Palpate peripheral pulses.
  • C. Auscultate breath sounds.
  • D. Check pupil reaction to light.
Correct Answer: C

Rationale: The correct answer is C: Auscultate breath sounds. After a near-drowning incident, the main concern is potential respiratory complications such as aspiration pneumonia or pulmonary edema. Auscultating breath sounds will help the nurse assess for any signs of respiratory distress or complications. This assessment is crucial for early detection and intervention.

A: Auscultating heart sounds is important but not as crucial as assessing breath sounds in this scenario.
B: Palpating peripheral pulses is important for circulation assessment but does not address the immediate concern of respiratory complications.
D: Checking pupil reaction to light is more relevant for neurological assessment and not as critical as assessing breathing in this situation.
