Which of the following assists the critical care nurse in ensuring that care is appropriate and based on research?
- A. Clinical practice guidelines
- B. Computerized physician order entry
- C. Consulting with advanced practice nurses
- D. Implementing Joint Commission National Patient Safe ty Goals
Correct Answer: A
Rationale: The correct answer is A: Clinical practice guidelines. Clinical practice guidelines are evidence-based recommendations that assist nurses in providing appropriate care based on research. They outline best practices for specific patient populations or conditions, helping nurses make informed decisions.
Summary:
- B: Computerized physician order entry: While it may improve accuracy and efficiency, it does not specifically ensure care based on research.
- C: Consulting with advanced practice nurses: While collaboration is valuable, it does not guarantee care based on research.
- D: Implementing Joint Commission National Patient Safety Goals: Important for patient safety, but not directly related to ensuring care based on research.

The critical care unit environment is very stressful for patients, families, and staff. What nursing action is directed at reducing environmental stress?
- A. Constant expert evaluation of patient status
- B. Limiting visits to immediate family
- C. Bathing all patients during hours of sleep
- D. Maintaining a quiet environment during hours of sleep
Correct Answer: D
Rationale: The correct answer is D: Maintaining a quiet environment during hours of sleep. This action is directed at reducing environmental stress in the critical care unit because noise and disturbances during sleep can negatively impact patients' rest and recovery. By ensuring a quiet environment, patients can have uninterrupted sleep, which is crucial for healing.
Rationale:
1. Constant expert evaluation of patient status (A) may be important but does not directly address environmental stress.
2. Limiting visits to immediate family (B) may hinder patients' emotional support and can be stressful for families.
3. Bathing all patients during hours of sleep (C) may disrupt patients' rest and increase stress levels rather than reduce it.
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.
A patient is being mechanically ventilated in the synchronized intermittent mandatory ventilation mode at a rate of 4 breaths/min. Spontaneous reabsiprbi.rcaotmio/tensst are 12 breaths/min. After receiving a dose of morphine sulfate, respirations decrease to 4 breaths/min. Which acid-base disturbance will likely occur?
- A. Metabolic acidosis
- B. Metabolic alkalosis
- C. Respiratory acidosis
- D. Respiratory alkalosis
Correct Answer: D
Rationale: The correct answer is D (Respiratory alkalosis). Morphine sulfate can cause respiratory depression, leading to decreased respiratory rate. In this case, the patient's breaths decrease from 12 to 4 breaths/min, indicating hypoventilation. With decreased ventilation, there is less CO2 elimination, resulting in respiratory alkalosis. The other choices can be ruled out: A (Metabolic acidosis) and B (Metabolic alkalosis) are less likely caused by morphine sulfate, and C (Respiratory acidosis) is incorrect because the scenario describes hypoventilation, not hyperventilation.
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.
When assessing an older patient admitted to the emergency department (ED) with a broken arm and facial bruises, the nurse observes several additional bruises in various stages of healing. Which statement or question by the nurse is most appropriate?
- A. Do you feel safe in your home?
- B. You should not return to your home.
- C. Would you like to see a social worker?
- D. I need to report my concerns to the police.
Correct Answer: A
Rationale: The correct answer is A: "Do you feel safe in your home?" This question is most appropriate because it directly addresses the potential issue of elder abuse without assuming or accusing the patient. It allows the patient to disclose any safety concerns and initiates a conversation about their well-being. Options B and D are inappropriate as they are accusatory and may escalate the situation. Option C is not as direct and may not effectively address the safety concerns of the patient.
