As part of the Synergy Model, the nurse has identified a patient characteristic of resiliency. What patient behavior demonstrates resiliency?
- A. Dysfunctional grieving behaviors after receiving bad news
- B. Developing a list of questions for the physician
- C. Denial of any possible negative outcomes for a procedure
- D. Assigning blame to others for undesired outcomes of illness
Correct Answer: B
Rationale: The correct answer is B because developing a list of questions for the physician shows active engagement in their healthcare, seeking information, and taking control of their situation, which are characteristics of resiliency. This behavior indicates the patient's willingness to understand and cope with their health condition. Choices A, C, and D are incorrect as they demonstrate maladaptive coping mechanisms such as dysfunctional grieving, denial, and blame assignment, which are not indicative of resiliency. Resiliency involves adaptability, problem-solving, and seeking support, which are better exemplified by choice B.

A statement that provides a legally recognized descriptiona obifrb a.cno min/tedsitv idual’s desires regarding care at the end of life is referred to as what?
- A. Advance directive
- B. Guardianship ad item
- C. Healthcare proxy
- D. Power of attorney
Correct Answer: A
Rationale: The correct answer is A: Advance directive. An advance directive is a legal document that outlines a person's wishes regarding medical treatment and care at the end of life. It allows individuals to specify their preferences for medical interventions if they become unable to communicate.
Summary of other choices:
B: Guardianship ad item - This does not specifically pertain to an individual's end-of-life care wishes.
C: Healthcare proxy - While similar to an advance directive, a healthcare proxy specifically designates a person to make medical decisions on behalf of the individual, rather than specifying their own wishes.
D: Power of attorney - This grants someone the authority to make legal decisions on behalf of the individual, but it does not specifically address end-of-life care preferences.
Which of the following are physiological effects of positive end-expiratory pressure (PEEP) used in the treatment of acute respiratory distress syndrom e (ARDS)? (Select all that apply.)
- A. Increase functional residual capacity
- B. Prevent collapse of unstable alveoli
- C. Improve arterial oxygenation
- D. Open collapsed alveoli
Correct Answer: A
Rationale: The correct answer is A: Increase functional residual capacity. Positive end-expiratory pressure (PEEP) helps increase the functional residual capacity by keeping the alveoli open at the end of expiration. This prevents alveolar collapse, improves ventilation-perfusion matching, and enhances oxygenation.
B: Prevent collapse of unstable alveoli - This is incorrect because PEEP actually helps prevent the collapse of all alveoli, not just unstable ones.
C: Improve arterial oxygenation - This is partially correct, but the primary mechanism through which PEEP improves oxygenation is by increasing functional residual capacity.
D: Open collapsed alveoli - This is incorrect because PEEP helps prevent alveolar collapse rather than actively opening already collapsed alveoli.
A Muslim woman is admitted to the ICU after suffering severe burns over most of her body. Which of the following would be the most appropriate measure for the nurse, a woman, to take in respect for the cultural practices of this patient?
- A. Insist that only a female doctor be assigned to this patient.
- B. Ensure that no pork products are included in the patients diet.
- C. Ensure that direct eye contact is not made with the patients husband.
- D. Ask the patients husband what religious and cultural preferences should be considered in the patients care.
Correct Answer: D
Rationale: The correct answer is D because it demonstrates respect for the patient's autonomy and individual preferences. By asking the patient's husband about religious and cultural preferences, the nurse acknowledges the importance of involving the family in decision-making and shows sensitivity to the patient's beliefs. This approach promotes cultural competence and patient-centered care.
Choice A is incorrect because insisting on a female doctor may not align with the patient's preferences and may limit the available medical staff. Choice B is also incorrect as dietary restrictions are not necessarily the most pressing issue in this scenario. Choice C is incorrect as it assumes a cultural practice without verifying the patient's specific preferences and may not be necessary or appropriate in this context.
A nurse is caring for an elderly man recently admitted to the ICU following a stroke. She assesses his cognitive function using a new cognitive assessment test she learned about in a recent article in a nursing journal. She then brings a cup of water and a straw to the patient because she observes that his lips are dry. Later, she has the patient sit in a wheelchair and takes him to have some blood tests performed. He objects at first, saying that he can walk on his own, but the nurse explains that it is hospital policy to use the wheelchair. That evening, she recognizes signs of an imminent stroke in the patient and immediately pages the physician. Which action taken by the nurse is the best example of evidence-based practice?
- A. Giving the patient a cup of water
- B. Transferring the patient in a wheelchair
- C. Recognizing signs of imminent stroke and paging the physician
- D. Using the cognitive assessment test
Correct Answer: C
Rationale: The correct answer is C: Recognizing signs of an imminent stroke and paging the physician. This action exemplifies evidence-based practice as it involves timely identification of a critical medical condition based on clinical assessment and prompt communication with the physician for further intervention. This aligns with the principles of evidence-based practice, which emphasize the integration of best available evidence with clinical expertise and patient values.
The other choices are incorrect:
A: Giving the patient a cup of water - While providing hydration is important for patient care, it does not demonstrate evidence-based practice in this scenario.
B: Transferring the patient in a wheelchair - Although using a wheelchair may be hospital policy, it does not directly relate to evidence-based practice in this context.
D: Using the cognitive assessment test - While assessing cognitive function is essential, it does not directly address the immediate medical needs of the patient as recognizing signs of an imminent stroke does.
When assisting with the placement of a pulmonary artery (PA) catheter, the nurse notes that the catheter is correctly placed when the monitor shows a:
- A. Typical PA pressure waveform.
- B. Tracing of the systemic arterial pressure.
- C. Tracing of the systemic vascular resistance.
- D. Typical PA wedge pressure (PAWP) tracing.
Correct Answer: D
Rationale: Step-by-step rationale for Answer D being correct:
1. PA catheter measures PA pressures.
2. PAWP reflects left atrial pressure.
3. Correct placement shows typical PAWP tracing.
4. PA pressure waveform (A) is not specific to PAWP.
5. Systemic arterial pressure tracing (B) is unrelated.
6. Systemic vascular resistance tracing (C) is not monitored by PA catheter.
