Which patient should the nurse notify the organ procureme nt organization (OPO) to evaluate for possible organ donation?
- A. A 36-year-old patient with a Glasgow Coma Scale score of 3 with no activity on electroencephalogram
- B. A 68-year-old male admitted with unstable atrial fibrillation who has suffered a stroke
- C. A 40-year-old brain-injured female with a history of ovabairrbi.acnom c/taenstc er and a Glasgow Coma Scale score of 7
- D. A 53-year-old diabetic male with a history of unstable angina status post resuscitation
Correct Answer: A
Rationale: The correct answer is A because the patient is a 36-year-old with a Glasgow Coma Scale score of 3 and no activity on electroencephalogram, indicating severe brain injury and likely irreversible neurological damage. This patient meets the criteria for potential organ donation as they are neurologically devastated.
Choice B is incorrect because the patient's condition is related to stroke and atrial fibrillation, not severe brain injury that would make them a candidate for organ donation.
Choice C is incorrect because although the patient has a brain injury and a lower Glasgow Coma Scale score, the history of a reversible cause (ovarian cancer metastasis) and a higher GCS score compared to choice A make this patient less suitable for organ donation evaluation.
Choice D is incorrect as the patient's diabetic and cardiovascular history does not suggest severe brain injury that would qualify for organ donation.

Which treatment can be used to dissolve a thrombus that is lodged in the pulmonary artery?
- A. Aspirin
- B. Embolectomy
- C. Heparin
- D. Thrombolytics
Correct Answer: D
Rationale: The correct answer is D: Thrombolytics. Thrombolytics are medications that can dissolve blood clots, making them effective in treating a thrombus lodged in the pulmonary artery. They work by activating the body's natural clot-dissolving system. Aspirin (A) is an antiplatelet drug and may prevent further clot formation but cannot dissolve an existing thrombus. Embolectomy (B) is a surgical procedure to remove a clot and is invasive, usually reserved for cases where thrombolytics are contraindicated. Heparin (C) is an anticoagulant that prevents clot formation but does not dissolve existing clots like thrombolytics do.
Which of the following are accepted nonpharmacological approaches to managing pain and/or anxiety in critically ill patients? (Select all that apply.)
- A. Environmental manipulation
- B. Explanations of monitoring equipment
- C. Guided imagery
- D. Music therapy
Correct Answer: A
Rationale: Step 1: Environmental manipulation involves adjusting factors like lighting, noise levels, and room temperature to create a soothing environment, which can help reduce pain and anxiety.
Step 2: By controlling the physical surroundings, patients may feel more comfortable and relaxed, leading to improved pain management and reduced anxiety levels.
Step 3: Explanations of monitoring equipment and guided imagery are not directly related to environmental changes that can impact pain and anxiety.
Step 4: Music therapy, while beneficial for some patients, is not categorized as environmental manipulation.
A patient presents to the emergency department in acute re spiratory failure secondary to community-acquired pneumonia. The patient has a history of chronic obstructive pulmonary disease. The nurse anticipates which treatment to facilitate ventilation?
- A. Emergency tracheostomy and mechanical ventilation
- B. Mechanical ventilation via an endotracheal tube
- C. Noninvasive positive-pressure ventilation (NPPV)
- D. Oxygen at 100% via bag-valve-mask device
Correct Answer: B
Rationale: The correct answer is B: Mechanical ventilation via an endotracheal tube. In acute respiratory failure, especially in the setting of pneumonia and COPD, mechanical ventilation is often necessary to support breathing. Endotracheal intubation allows for precise control of airway patency, oxygenation, and ventilation. Emergency tracheostomy (choice A) is typically reserved for long-term ventilatory support. Noninvasive positive-pressure ventilation (choice C) may not provide sufficient support in severe cases. Oxygen via bag-valve-mask (choice D) may not be adequate for ventilatory support in acute respiratory failure.
What risk is the rationale for the recommendation of endot racheal rather than nasotracheal intubation?
- A. Basilar skull fracture
- B. Cervical hyperextension
- C. Impaired ability to "mouth" words
- D. Sinusitis and infection
Correct Answer: A
Rationale: The correct answer is A: Basilar skull fracture. Endotracheal intubation is recommended over nasotracheal intubation to avoid the risk of further damaging a basilar skull fracture. Nasotracheal intubation can potentially cause further injury due to the passage of the tube through the nasal cavity, which could exacerbate a basilar skull fracture.
Summary of other choices:
B: Cervical hyperextension - Not directly related to the choice between endotracheal and nasotracheal intubation.
C: Impaired ability to "mouth" words - Not a significant factor in determining the choice of intubation method.
D: Sinusitis and infection - While nasotracheal intubation can potentially lead to sinusitis and infection, the primary concern in this scenario is the risk of aggravating a basilar skull fracture.
A nurse is on a committee that is trying to reduce the occurrence of hospital-acquired infections in the ICU. Her role is to conduct research to find which interventions have been shown to be most effective in reducing these infections. She consults many different sources and finds conflicting information. Which of the following sources should she consider the most authoritative?
- A. AACN expert panel report
- B. A meta-analysis of randomized controlled trials in the American Journal of Nursing
- C. A systematic review of qualitative studies in the Journal of Advanced Nursing
- D. A single randomized controlled trial in the American Journal of Critical Care
Correct Answer: B
Rationale: The correct answer is B: A meta-analysis of randomized controlled trials in the American Journal of Nursing.
1. Meta-analyses provide a comprehensive overview of multiple studies, increasing the reliability of the findings.
2. Randomized controlled trials are considered the gold standard in research design for assessing intervention effectiveness.
3. The American Journal of Nursing is a reputable source in the field of nursing, ensuring the credibility of the study.
4. By synthesizing data from various trials, the meta-analysis can offer a more robust and generalizable conclusion compared to a single trial or qualitative studies.
Incorrect choices:
A: AACN expert panel report - Expert opinions may vary and lack the empirical evidence provided by research studies.
C: A systematic review of qualitative studies in the Journal of Advanced Nursing - Qualitative studies may provide valuable insights but may not offer concrete evidence on intervention effectiveness like quantitative studies.
D: A single randomized controlled trial in the American Journal of Critical Care - Single trials may not capture the full picture and
