The nurse is caring for a patient whose ventilator settings i nclude 15 cm H O of positive end-expiratory pressure (PEEP). The nurse understands that although beneficial, PEEP may result in what possible problem?
- A. Fluid overload secondary to decreased venous return.
- B. High cardiac index secondary to more efficient ventric ular function.
- C. Hypoxemia secondary to prolonged positive pressure a t expiration.
- D. Low cardiac output secondary to increased intrathoracic pressure
Correct Answer: D
Rationale: Rationale for Correct Answer (D - Low cardiac output secondary to increased intrathoracic pressure):
1. PEEP increases intrathoracic pressure, which can impede venous return to the heart.
2. Impaired venous return reduces preload, leading to decreased cardiac output.
3. Decreased cardiac output can result in inadequate tissue perfusion and oxygenation.
4. Therefore, PEEP may cause low cardiac output due to increased intrathoracic pressure.
Summary of Incorrect Choices:
A. Fluid overload is not directly related to PEEP but more to fluid administration or kidney function.
B. High cardiac index is unlikely as PEEP can decrease cardiac output.
C. Hypoxemia is not a direct result of PEEP but may occur due to other factors like inadequate ventilation or oxygenation settings.

The nursing is caring for a patient who has had an arterial line inserted. To reduce the risk of complications, what is the priority nursing intervention?
- A. Apply a pressure dressing to the insertion site.
- B. Ensure all tubing connections are tightened.
- C. Obtain a portable x-ray to confirm placement.
- D. Restrain the affected extremity for 24 hours.
Correct Answer: C
Rationale: The correct answer is C: Obtain a portable x-ray to confirm placement. This is the priority intervention because it ensures the arterial line is correctly positioned, reducing the risk of complications such as dislodgement or improper placement. Applying a pressure dressing (choice A) may be necessary but is not the priority. Ensuring tubing connections are tightened (choice B) is important for preventing leaks but does not address placement. Restraining the affected extremity (choice D) is unnecessary and can lead to complications. The x-ray confirms correct placement, ensuring accurate monitoring and treatment.
Which statement is a likely response from someone who h as survived a stay in the critical care unit?
- A. “I don’t remember much about being in the ICU, but if I had to be treated there again, it would be okay. I’m glad I can see my grandchildren again.”
- B. “If I get that sick again, do not take me to the hospital. I would rather die than go through having a breathing tube put in again.”
- C. “My family is thrilled that I am home. I know I need some extra attention, but my children have rearranged their schedules to help me ou t.”
- D. “Since I have been transferred out of the ICU, I cannot get enough to eat. They didn’t let me eat in the ICU, so I’m making up for it no w.”
Correct Answer: A
Rationale: Rationale: Choice A is the correct answer because it reflects a positive attitude towards potential future treatments in the critical care unit and gratitude for being able to see family again. The survivor acknowledges the past experience but remains optimistic.
Summary:
- Choice B is incorrect as it shows a strong aversion to hospital care, indicating a preference for death over treatment.
- Choice C is incorrect as it focuses on the family's reaction and not the survivor's personal experience or perspective.
- Choice D is incorrect as it highlights a trivial aspect (eating) rather than reflecting on the ICU experience or future treatments.
The nurse is caring for 80-year-old patient who has been tr eated for gastrointestinal bleeding. The family has agreed to withhold or withdraw additional treatment. The patient has a written advance directive specifying requests. The directive notes that the patient wants food and fluid to be continued and to be made physically comfortable. Th e nurse anticipates that several orders may be written to comply with this request, including which of the following? (Select all that apply.)
- A. “Do not resuscitate.”
- B. Change antibiotic to a less expensive medication.
- C. Discontinue tube feeding.
- D. Stop any further blood transfusions.
Correct Answer: A
Rationale: The correct answer is A: "Do not resuscitate." In this scenario, the patient's advance directive specifies a desire for comfort measures and continuation of food and fluids. A DNR order aligns with this directive by respecting the patient's wish to avoid aggressive life-saving measures. This choice prioritizes the patient's autonomy and quality of life. Other options (B, C, D) are not aligned with the patient's wishes. Changing antibiotics or stopping blood transfusions may be unrelated to the patient's comfort or food/fluid preferences. Discontinuing tube feeding goes against the directive's request for food and fluid continuation.
A nurse walks into a patients room and begins preparing a syringe to perform a blood draw on the patient. The nurse observes that the patient is firmly gripping the side of the bed, averting her eyes, and sweating from her forehead when she sees the needle. What would be the best intervention for the nurse to make?
- A. Proceed with blood draw as quickly as possible, to get it over with.
- B. Offer to come back later to perform the blood draw.
- C. Encourage the patient to deep breathe.
- D. Describe briefly the blood draw procedure and explain why it is necessary.
Correct Answer: D
Rationale: The correct answer is D because it shows empathy and promotes patient education. By describing the procedure and its necessity, the nurse can alleviate the patient's anxiety and build trust. This approach allows the patient to feel informed and in control, reducing fear and increasing cooperation. It also demonstrates respect for the patient's feelings and promotes a therapeutic relationship.
Choice A is incorrect as it disregards the patient's fear and can lead to increased distress. Choice B might be an option, but it doesn't address the patient's anxiety in the moment. Choice C, while helpful in some cases, doesn't directly address the patient's specific fear of the blood draw procedure.
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
