The nurse is caring for a 100-kg patient being monitored with a pulmonary artery catheter. The nurse assesses a blood pressure of 90/60 mm Hg, hear t rate 110 beats/min, respirations 36/min, oxygen saturation of 89% on 3 L of oxygen via nasal cannula. Bilateral crackles are audible upon auscultation. Which hemodynamic value reqaubiirrbe.sco imm/temste diate action by the nurse?
- A. Cardiac index (CI) of 1.2 L/min/m3
- B. Cardiac output (CO) of 4 L/min
- C. Pulmonary vascular resistance (PVR) of 80 dynes/sec/cm5
- D. Systemic vascular resistance (SVR) of 1800 dynes/sec /cm5
Correct Answer: B
Rationale: The correct answer is B: Cardiac output (CO) of 4 L/min. In this scenario, the patient is presenting with signs of pulmonary congestion and hypoxemia, indicating possible cardiogenic pulmonary edema. As the cardiac output is a key indicator of how well the heart is functioning and delivering blood to the body, a low cardiac output can lead to inadequate tissue perfusion and worsen the patient's condition. Therefore, immediate action is required to address the low cardiac output to improve tissue perfusion and oxygenation.
Choices A, C, and D are incorrect as they do not directly address the primary concern of inadequate cardiac output in this patient. Cardiac index, pulmonary vascular resistance, and systemic vascular resistance are important parameters to monitor, but in this case, the priority is to address the low cardiac output to improve the patient's condition.

Continuous renal replacement therapy (CRRT) differs from conventional intermittent hemodialysis in that
- A. a hemofilter is used to facilitate ultrafiltration.
- B. it provides faster removal of solute and water.
- C. it does not allow diffusion to occur.
- D. the process removes solutes and water slowly.
Correct Answer: D
Rationale: The correct answer is D because CRRT removes solutes and water slowly, which is beneficial for hemodynamically unstable patients. This slow removal allows for gradual fluid and electrolyte balance adjustments, reducing the risk of hemodynamic instability.
A: Incorrect - A hemofilter is indeed used in CRRT, but this choice does not highlight the key difference between CRRT and intermittent hemodialysis.
B: Incorrect - CRRT actually provides slower solute and water removal compared to intermittent hemodialysis.
C: Incorrect - Diffusion does occur in CRRT, as it is a key mechanism for solute removal in the process.
In summary, the key difference between CRRT and intermittent hemodialysis is the slow removal of solutes and water in CRRT, making choice D the correct answer.
Which statement reflects adherence to current recommendations concerning open visitation policies?
- A. Allowing animals on the unit; however, these can only be “therapy” animals through the hospital’s pet therapy program.
- B. Allowing family visitation throughout the day except a t change of shift and during rounds.
- C. Determining, in collaboration with the patient and famaiblyirb, .cwomho/te csta n visit and when.
- D. Permitting open visitation by adults 18 years of age and older; limit visits of children to 1 hour.
Correct Answer: C
Rationale: The correct answer is C because it reflects patient-centered care by involving patients and families in decision-making. Collaborating with them on visitation preferences promotes a supportive environment. Choice A restricts animal visitation, not addressing human visitors. Choice B limits visitation during specific times, not individualized. Choice D imposes restrictions based on age, not on patient/family preferences. Therefore, Choice C is the most aligned with current recommendations for open visitation policies.
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.
A 28-year-old patient who has deep human bite wounds on the left hand is being treated in the urgent care center. Which action will the nurse plan to take?
- A. Prepare to administer rabies immune globulin (BayRab).
- B. Assist the health care provider with suturing the bite wounds.
- C. Teach the patient the reason for the use of prophylactic antibiotics.
- D. Keep the wounds dry until the health care provider can assess them.
Correct Answer: C
Rationale: The correct answer is C: Teach the patient the reason for the use of prophylactic antibiotics. This is the most important action because human bites can introduce harmful bacteria into the wound, leading to infection. Prophylactic antibiotics help prevent infection in deep human bite wounds.
Choice A is incorrect because rabies immune globulin is not indicated for human bite wounds. Choice B is incorrect because suturing human bite wounds can trap bacteria and increase the risk of infection. Choice D is incorrect because keeping the wounds dry is not sufficient; proper wound cleaning and antibiotic treatment are essential in this case.
Following insertion of a central venous catheter, the nurse obtains a stat chest x-ray film to verify proper catheter placement. The radiologist reports to the nurse: “The tip of the catheter is located in the superior vena cava.” What is the best inter pretation of these results by the nurse?
- A. The catheter is not positioned correctly and should be removed.
- B. The catheter position increases the risk of ventricular daybisrbr.hcoymth/tmesti as.
- C. The distal tip of the catheter is in the appropriate position.
- D. The physician should be called to advance the catheter into the pulmonary artery.
Correct Answer: C
Rationale: The correct answer is C: The distal tip of the catheter is in the appropriate position.
Rationale:
1. The superior vena cava is a desirable location for a central venous catheter tip placement as it is close to the heart for rapid medication delivery.
2. Catheter tip in the superior vena cava allows for proper venous return and minimizes the risk of complications.
3. The nurse does not need to remove or adjust the catheter if the tip is in the superior vena cava.
4. Advancing the catheter into the pulmonary artery (option D) would be incorrect as it can lead to serious complications.
Incorrect choices:
A: Incorrect because placement in the superior vena cava is acceptable.
B: Incorrect as placement in the superior vena cava does not increase the risk of ventricular dysrhythmias.
D: Incorrect as advancing the catheter into the pulmonary artery is unnecessary and risky.
