Nokea
The patient is getting hemodialysis for the second time when he complains of a headache and nausea and, a little later, of becoming confused. The nurse realizes these are symptoms of
- A. dialyzer membrane incompatibility.
- B. a shift in potassium levels.
- C. dialysis disequilibrium syndrome.
- D. hypothermia.
Correct Answer: C
Rationale: The correct answer is C: dialysis disequilibrium syndrome. This occurs when there is a rapid decrease in urea concentration in the blood during hemodialysis, causing fluid shifts and cerebral edema leading to symptoms like headache, nausea, and confusion. Dialyzer membrane incompatibility (A) would present with allergic reactions, not neurological symptoms. A shift in potassium levels (B) may cause muscle weakness or cardiac arrhythmias, but not the described symptoms. Hypothermia (D) would present with low body temperature and shivering, not the neurological symptoms mentioned.

The patient is in need of immediate hemodialysis, but has no vascular access. The nurse prepares the patient for insertion of
- A. a percutaneous catheter at the bedside.
- B. a percutaneous tunneled catheter at the bedside.
- C. an arteriovenous fistula.
- D. an arteriovenous graft.
Correct Answer: A
Rationale: The correct answer is A: a percutaneous catheter at the bedside. This is the most appropriate option for immediate hemodialysis when the patient has no vascular access. A percutaneous catheter can be quickly inserted at the bedside, allowing for immediate initiation of hemodialysis.
Choice B, a percutaneous tunneled catheter, involves a more complex insertion process and is not typically done at the bedside. Choices C and D, arteriovenous fistula and arteriovenous graft, require advanced planning and surgical procedures, making them unsuitable for immediate hemodialysis in this scenario.
A patient is admitted to the ICU with injuries sustained from a fall from a third-story window. The patient is conscious, his breathing is labored, and he is bleeding heavily from the abdomen. He groans constantly and complains of severe pain, but his movements are minimal. His heart rate is elevated. Which of these is a sign that he is in the second phase of the stress response? Select all that apply.
- A. Bleeding heavily from his abdomen
- B. Labored, slow breathing
- C. Severe pain
- D. Elevated heart rate
Correct Answer: C
Rationale: The correct answer is C: Severe pain. In the second phase of the stress response (resistance phase), the body is trying to cope with the stressor. Severe pain is a sign of the body's response to the injury, indicating the activation of the stress response. Labored breathing and elevated heart rate are more likely to be signs of the initial phase (alarm phase) of the stress response. Bleeding heavily from the abdomen is a medical emergency and does not specifically indicate the stress response phase.
An 81-year-old patient who has been in the intensive care unit (ICU) for a week is now stable, and transfer to the progressive care unit is planned. On rounds, the nurse notices that the patient has new onset confusion. The nurse will plan to:
- A. Give PRN lorazepam (Ativan) and cancel the transfer.
- B. Inform the receiving nurse and then transfer the patient.
- C. Notify the health care provider and postpone the transfer.
- D. Obtain an order for restraints as needed and transfer the patient.
Correct Answer: C
Rationale: The correct answer is C: Notify the health care provider and postpone the transfer. The new onset confusion in an elderly patient in the ICU can be a sign of delirium, which is a serious condition that requires prompt evaluation and management. By notifying the healthcare provider, they can assess the patient's condition, order appropriate tests, and adjust the treatment plan as needed. Postponing the transfer allows for further observation and intervention to address the underlying cause of the confusion.
Choice A (Give PRN lorazepam and cancel the transfer) is incorrect because administering lorazepam may worsen the confusion in an elderly patient and should not be done without proper evaluation.
Choice B (Inform the receiving nurse and then transfer the patient) is incorrect because transferring the patient without addressing the new onset confusion can lead to potential complications and delay in appropriate management.
Choice D (Obtain an order for restraints as needed and transfer the patient) is incorrect because using restraints should only be considered as a
Four hours after mechanical ventilation is initiated for a patient with chronic obstructive pulmonary disease (COPD), the patient’s arterial blood gas (ABG) results include a pH of 7.51, PaO2 of 82 mm Hg, PaCO2 of 26 mm Hg, and HCO3 of 23 mEq/L (23 mmol/L). The nurse will anticipate the need to:
- A. Increase the FIO2.
- B. Increase the tidal volume.
- C. Increase the respiratory rate.
- D. Decrease the respiratory rate.
Correct Answer: D
Rationale: The correct answer is D: Decrease the respiratory rate. The ABG results show respiratory alkalosis with decreased PaCO2 and elevated pH. This indicates overventilation, so decreasing the respiratory rate will help normalize the PaCO2 and pH levels. Increasing the FIO2 (Choice A) is not needed as the PaO2 is within normal range. Increasing tidal volume (Choice B) can lead to further hyperventilation. Increasing the respiratory rate (Choice C) would exacerbate the respiratory alkalosis.
The AACN Standards for Acute and Critical Care Nursing Practice uses what framework to guide critical care nursing practice?
- A. Evidence-based practice
- B. Healthy work environment
- C. National Patient Safety Goals
- D. Nursing process
Correct Answer: A
Rationale: The correct answer is A: Evidence-based practice. The AACN Standards for Acute and Critical Care Nursing Practice emphasize the use of evidence-based practice to guide critical care nursing. This framework ensures that nursing interventions are based on the best available evidence, leading to improved patient outcomes. Healthy work environment (B) and National Patient Safety Goals (C) are important but not specific frameworks for critical care nursing. The nursing process (D) is a systematic approach to delivering patient care but is not the primary guiding framework in critical care nursing practice.
