The nurse is preparing to measure the thermodilution cardaiabicrb o.cuomtp/tuest t (TdCO) in a patient being monitored with a pulmonary artery catheter. Which action by the nurse best ensures the safety of the patient?
- A. Ensure the transducer system is zero referenced at the level of the phlebostatic axis.
- B. Avoid infusing vasoactive agents in the port used to ob tain the TdCO measurement.
- C. Maintain a pressure of 300 mm Hg on the flush solutioanbi rub.scionmg/t eas tp ressure bag.
- D. Limit the length of the noncompliant pressure tubing to a maximum 48 inches.
Correct Answer: B
Rationale: The correct answer is B: Avoid infusing vasoactive agents in the port used to obtain the TdCO measurement. This action ensures patient safety by preventing the introduction of vasoactive agents directly into the bloodstream during the measurement process. Infusing vasoactive agents can lead to inaccurate TdCO readings and potentially harm the patient.
Choice A is incorrect because zero referencing the transducer system at the level of the phlebostatic axis is important for accurate pressure monitoring but not directly related to TdCO measurement safety.
Choice C is incorrect as maintaining a pressure of 300 mm Hg on the flush solution bag is not directly related to the safety of TdCO measurement.
Choice D is incorrect as limiting the length of noncompliant pressure tubing is important for accurate pressure readings but not directly related to the safety of TdCO measurement.

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.
Which nursing interventions would best support the family of a critically ill patient?
- A. Encouraging family members to stay all night in case t he patient needs them.
- B. Giving a condition update each morning and whenever changes occur.
- C. Limiting visitation from children into the critical care u nit.
- D. Providing beverages and snacks in the waiting room.
Correct Answer: B
Rationale: The correct answer is B because giving regular condition updates promotes transparency and communication, reducing anxiety for the family. This intervention helps them stay informed and involved in the patient's care. Choice A may lead to caregiver fatigue and is not sustainable. Choice C limits family support and may increase stress. Choice D focuses on comfort but does not address the family's need for information.
The nurse is caring for a patient following insertion of a left subclavian central venous catheter (CVC). Which action by the nurse best reduces th e risk of catheter-related bloodstream infection (CRBSI)?
- A. Review daily the necessity of the central venous cathet er.
- B. Cleanse the insertion site daily with isopropyl alcohol.
- C. Change the pressurized tubing system and flush bag daily.
- D. Maintain a pressure of 300 mm Hg on the flush bag.
Correct Answer: A
Rationale: The correct answer is A: Review daily the necessity of the central venous catheter. This action reduces the risk of CRBSI by promoting early removal of unnecessary catheters, which is a key strategy in preventing infections. Unnecessary catheters increase the risk of infection due to prolonged exposure to the patient's skin flora and possible contamination during insertion. Reviewing daily ensures the catheter is only kept when necessary, minimizing the duration of catheter use and reducing the chances of infection.
Summary of other choices:
B: Cleansing the insertion site daily with isopropyl alcohol is important for maintaining skin integrity but does not directly reduce the risk of CRBSI.
C: Changing the pressurized tubing system and flush bag daily is important for maintaining catheter patency but does not directly reduce the risk of CRBSI.
D: Maintaining a pressure of 300 mm Hg on the flush bag is important for proper catheter function but does not directly reduce the risk of CR
Following surgery for an abdominal aortic aneurysm, the patient’s central venous pressure (CVP) monitor indicates low pressures. Which action is a priority for the nurse to take?
- A. Administer IV diuretic medications.
- B. Increase the IV fluid infusion per protocol.
- C. Document the CVP and continue to monitor.
- D. Elevate the head of the patient's bed to 45 degrees.
Correct Answer: B
Rationale: The correct answer is B: Increase the IV fluid infusion per protocol. Low CVP post-abdominal aortic aneurysm surgery could indicate hypovolemia, which requires fluid resuscitation. Increasing IV fluid infusion helps restore intravascular volume, improve tissue perfusion, and prevent hypotension. Administering diuretics (A) would worsen hypovolemia. Documenting (C) is important but not the priority when the patient needs immediate intervention. Elevating the head of the bed (D) may help with venous return but is not the priority over addressing hypovolemia.
The nurse admits a terminally ill patient to the hospital. What is the first action that the nurse should complete when planning this patient care?
- A. Determine the patient’s wishes regarding end-of-life care.
- B. Emphasize the importance of addressing any family issues.
- C. Discuss the normal grief process with the patient and family.
- D. Encourage the patient to talk about any fears or unresolved issues.
Correct Answer: A
Rationale: The correct answer is A because determining the patient's wishes regarding end-of-life care is crucial in providing patient-centered care and ensuring that the patient's preferences are respected. By understanding the patient's preferences, healthcare providers can tailor the care plan to align with the patient's values and goals. This helps in promoting autonomy, dignity, and quality of life for the patient.
Choices B, C, and D are incorrect because although addressing family issues, discussing grief, and encouraging the patient to express fears are important aspects of caring for a terminally ill patient, they are not the first action that should be completed. Prioritizing the patient's wishes ensures that the care plan is centered around the patient's needs and preferences, which is essential in providing holistic and patient-centered care.
