A nurse wishes to practice using the Synergy Model developed by the American Association of Critical-Care Nurses (AACN). What nursing behavior best supports use of this model?
- A. Attending mandatory hospital-wide in-service programs
- B. Self-directed study of best practice for the patients she cares for
- C. Gathering demographic data on the patients admitted to the unit
- D. Participating in a research study as a data collector
Correct Answer: B
Rationale: The correct answer is B: Self-directed study of best practice for the patients she cares for. This choice aligns with the Synergy Model by promoting individualized patient care based on best practices. Self-directed study allows the nurse to enhance their knowledge and skills to provide optimal care tailored to each patient's unique needs. Attending mandatory in-service programs (A) may not directly support the individualized care approach. Gathering demographic data (C) is important but not specific to the Synergy Model's focus on patient acuity and nurse competencies. Participating in a research study (D) may contribute to evidence-based practice, but it does not directly relate to the Synergy Model's emphasis on aligning nurse competencies with patient needs.

The patient’s serum creatinine level is 0.7 mg/dL. The expected BUN level should be
- A. 1 to 2 mg/dL.
- B. 7 to 14 mg/dL.
- C. 10 to 20 mg/dL.
- D. 20 to 30 mg/dL.
Correct Answer: C
Rationale: The correct answer is C (10 to 20 mg/dL). The normal BUN-to-creatinine ratio is approximately 10:1. With a serum creatinine level of 0.7 mg/dL, the expected BUN level should be around 7 to 14 mg/dL. Therefore, choice C (10 to 20 mg/dL) falls within this expected range. Choices A, B, and D are incorrect as they do not align with the typical BUN-to-creatinine ratio and would indicate abnormal kidney function.
The nurse is caring for a patient with a left radial arterial lianbierb, .caonmd/t eas tp ulmonary artery catheter inserted into the right subclavian vein. Which action by th e nurse best ensures the safety of the patient being monitored with invasive hemodynamic moni toring lines?
- A. Document all waveform values.
- B. Limit the pressure tubing length.
- C. Zero reference the system daily.
- D. Ensure alarm limits are turned on.
Correct Answer: C
Rationale: The correct answer is C: Zero reference the system daily. Zero referencing ensures accuracy and calibration of pressure monitoring system by setting the baseline pressure to zero. This is crucial to prevent inaccuracies in measurements. Choice A is important but doesn't directly address the accuracy of the monitoring system. Choice B may help in preventing errors but doesn't address the accuracy of pressure measurement. Choice D is important for alerting the nurse but doesn't directly relate to the accuracy of hemodynamic monitoring.
Both the electroencephalogram (EEG) monitor and the Bis pectral Index Score (BIS) or Patient State Index (PSI) analyzer monitors are used to ass ess patient sedation levels in critically ill patients. Why are the BIS and PSI monitors simpler to use?
- A. They are only be used on heavily sedated patients.
- B. They can only be used on pediatric patients.
- C. They provide raw EEG data and a numeric value.
- D. They require only five leads.
Correct Answer: C
Rationale: The correct answer is C because BIS and PSI monitors provide both raw EEG data and a numeric value, simplifying the interpretation of patient sedation levels. Raw EEG data offers detailed information on brain activity, while the numeric value allows for quick assessment. This simplifies the monitoring process compared to interpreting raw EEG data alone.
Choice A is incorrect as BIS and PSI monitors are not restricted to heavily sedated patients. Choice B is incorrect as they are not limited to pediatric patients. Choice D is incorrect as the number of leads required does not determine the simplicity of use; it is the data interpretation that matters.
The nurse plans a teaching session with a client but postpones the planned session based on which nursing problem?
- A. Knowledge deficit regarding impending surgery.
- B. Ineffective management of treatment regimen.
- C. Activity intolerance related to postoperative pain.
- D. Noncompliance with prescribed exercise plan.
Correct Answer: C
Rationale: Step-by-step rationale for choice C:
1. Activity intolerance is a priority nursing problem postoperatively due to pain.
2. Postoperative pain can limit the client's ability to perform activities.
3. Addressing activity intolerance is crucial for promoting recovery and preventing complications.
4. Delaying the teaching session helps the nurse focus on managing pain first.
Summary of why other choices are incorrect:
- Choice A: Knowledge deficit can be addressed after managing immediate postoperative issues.
- Choice B: Treatment regimen management is important but may not be as urgent as addressing activity intolerance related to pain.
- Choice D: Noncompliance with exercise plan can be addressed once the client's pain and activity intolerance are under control.
A nurse needs to communicate with a patients family regarding consent to treat an unconscious patient in the ICU. Which member of the group should the nurse approach first?
- A. A man she recognizes as the patients brother
- B. A teenage boy who approaches the nurse
- C. A woman who originally escorted the patient in
- D. A woman in the group whom the others look at and call over when the nurse approaches
Correct Answer: C
Rationale: The correct answer is C: A woman who originally escorted the patient in. This choice is correct because she is most likely the person responsible for the patient's care and thus likely has legal authority to make medical decisions on behalf of the patient. The other choices are incorrect because simply being recognized as the patient's brother (A), being a teenage boy who approaches the nurse (B), or being a woman whom the others look at and call over (D) does not necessarily indicate that they have the legal authority to make medical decisions for the unconscious patient.
