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

Which interventions may be included during “terminal we aning”? (Select all that apply.)
- A. Complete extubation following ventilator withdrawal
- B. Discontinuation of artificial ventilation but maintenanc e of the artificial airway
- C. Discontinuation of anxiolytic and pain medications
- D. Titration of ventilator support based upon blood gas de terminations
Correct Answer: B
Rationale: The correct answer is B because during terminal weaning, the artificial ventilation is discontinued while maintaining the artificial airway to ensure comfort and support. This allows the patient to breathe on their own with support as needed.
Explanation:
1. Option A: Complete extubation following ventilator withdrawal may not be suitable during terminal weaning as it involves removing the breathing tube entirely.
2. Option C: Discontinuation of anxiolytic and pain medications may not always be appropriate during terminal weaning as it depends on the patient's comfort needs.
3. Option D: Titration of ventilator support based on blood gas determinations is not typically done during terminal weaning as the focus is on gradual withdrawal of ventilation support while maintaining comfort.
The patient is admitted to the unit with the diagnosis of rhabdomyolysis. The patient is started on intravenous (IV) fluids and IV mannitol. What action by the nurse is best?
- A. Assess the patient’s hearing.
- B. Assess the patient’s lungs.
- C. Decrease IV fluids once the diuretic has been administered.
- D. Give extra doses before giving radiological contrast agents.
Correct Answer: B
Rationale: The correct answer is B: Assess the patient’s lungs. Rhabdomyolysis can lead to acute kidney injury due to myoglobin release from damaged muscle cells. IV fluids and mannitol are given to prevent kidney damage by promoting myoglobin excretion. Assessing the patient’s lungs is crucial to monitor for potential complications such as acute respiratory distress syndrome (ARDS) which can occur as a result of rhabdomyolysis. This assessment helps to ensure early detection and prompt intervention if respiratory issues arise.
Summary of Incorrect Choices:
A: Assess the patient’s hearing - This is not directly related to rhabdomyolysis or its treatment.
C: Decrease IV fluids once the diuretic has been administered - Decreasing IV fluids can exacerbate kidney injury in rhabdomyolysis.
D: Give extra doses before giving radiological contrast agents - Mannitol is not routinely given before radiological contrast agents in the context of rhabdomyolysis management.
A patient is declared brain dead and a do not resuscitate (DNR) order is put in place. The nurse caring for the patient does not agree with this manne r of care but does not express any concerns to the charge nurse. The nurse’s feeling that the p atient is being killed will likely create what response for this nurse?
- A. A sense of abandonment
- B. Increased family stress
- C. Moral distress
- D. A sense of negligence
Correct Answer: C
Rationale: The correct answer is C: Moral distress. In this scenario, the nurse is experiencing conflicting moral values between the decision made for the patient and their own beliefs. This internal conflict leads to moral distress, a common response when healthcare professionals feel unable to act in accordance with their ethical beliefs. This can lead to emotional turmoil, frustration, and moral residue.
A: A sense of abandonment is incorrect because the nurse is still caring for the patient, so there is no physical abandonment.
B: Increased family stress is incorrect as the nurse's internal conflict does not directly impact family stress.
D: A sense of negligence is incorrect as negligence implies failure to provide proper care, which is not the case here.
A patient is being mechanically ventilated in the synchronized intermittent mandatory ventilation mode at a rate of 4 breaths/min. Spontaneous re spirations are 12 breaths/min. The patient receives a dose of morphine sulfate, and now respi rations decrease to 4 breaths/min. What adjustments may need to be made to the patient’s ve ntilator settings?
- A. Add positive end-expiratory pressure (PEEP).
- B. Add pressure support.
- C. Change to assist/control ventilation at a rate of 4 breathabsi/rmb.cionm. /test
- D. Increase the synchronized intermittent mandatory ventilation respiratory rate.
Correct Answer: C
Rationale: The correct answer is C: Change to assist/control ventilation at a rate of 4 breaths/min. When the patient's spontaneous respirations decrease to match the ventilator rate, it indicates that the patient is not actively participating in breathing. Changing to assist/control ventilation allows the patient to trigger breaths when they desire, ensuring a more synchronized and comfortable breathing pattern.
A: Adding PEEP may help improve oxygenation but is not directly related to the issue of decreased spontaneous respirations.
B: Adding pressure support provides additional support during inspiration but does not address the underlying issue of decreased spontaneous respirations.
D: Increasing the SIMV respiratory rate would not address the patient's decreased spontaneous respirations and could potentially lead to overventilation.
A patient in the ICU has recently been diagnosed with diabetes mellitus. Before being discharged, this patient will require detailed instructions on how to manage her diet, how to self-inject insulin, and how to handle future diabetic emergencies. Which nurse competency is most needed in this situation?
- A. Clinical judgment
- B. Advocacy and moral agency
- C. Caring practices
- D. Facilitation of learning
Correct Answer: D
Rationale: The correct answer is D: Facilitation of learning. In this scenario, the nurse needs to effectively educate the patient on managing her diet, insulin injections, and handling emergencies. Facilitation of learning involves assessing the patient's learning needs, providing relevant information, demonstrating skills, and evaluating understanding. This competency is crucial for promoting patient education and empowerment in managing their condition.
A: Clinical judgment involves making decisions based on assessment data, which is important but not the primary focus in this situation.
B: Advocacy and moral agency involve standing up for patients' rights and values, which is important but not as directly relevant to the patient's education needs.
C: Caring practices involve showing empathy and compassion, which are essential but not the main competency required for educational purposes in this case.
