The nurse is caring for a patient who has an arterial catheter in the radial artery to monitor blood pressure. Which of the following information obtained by the nurse is most important to report to the health care provider?
- A. The patient has a positive Allen test.
- B. The mean arterial pressure (MAP) is 86 mm Hg.
- C. There is redness at the catheter insertion site.
- D. The dicrotic notch is visible in the waveform.
Correct Answer: C
Rationale: Redness at the catheter insertion site indicates possible infection. The Allen test is performed before arterial line insertion, and a positive test indicates normal ulnar artery perfusion. An MAP of 86 is normal and the dicrotic notch is normally present on the arterial waveform.

A patient has a nursing diagnosis of disturbed sleep pattern related to difficulty maintaining sleep state. Which of the following actions should the nurse include in the plan of care?
- A. Discontinue assessments during the night to allow uninterrupted sleep.
- B. Administer prescribed sedatives or opioids at bedtime to promote sleep.
- C. Silence monitor alarms to allow 30- to 40-minute rest periods.
- D. Cluster nursing activities so that the patient has uninterrupted rest periods.
Correct Answer: D
Rationale: Clustering nursing activities and providing uninterrupted rest periods will minimize sleep-cycle disruption. Sedative and opioid medications tend to decrease the amount of rapid eye movement (REM) sleep and can contribute to sleep disturbance and disturbed sensory perception. Silencing the alarms on the cardiac monitors would be unsafe in a critically ill patient, as would discontinuing assessments during the night.
The nurse is caring for an older-adult patient who has stabilized after being in the intensive care unit (ICU) for a week and is preparing for transfer to the step-down unit when the nurse notices that the patient has new onset confusion. Which of the following actions should the nurse implement?
- A. Inform the receiving nurse and then transfer the patient.
- B. Notify the health care provider and postpone the transfer.
- C. Administer PRN lorazepam and cancel the transfer.
- D. Obtain an order for restraints as needed and transfer the patient.
Correct Answer: A
Rationale: The patient's history and symptoms most likely indicate delirium associated with the sleep deprivation with sensory overload in the ICU environment. Informing the receiving nurse and transferring the patient is appropriate. Postponing the transfer is likely to prolong the delirium. Benzodiazepines and restraints contribute to delirium and agitation.
The nurse notes thick, white respiratory secretions from a patient who is receiving mechanical ventilation. Which of the following interventions will be most effective in resolving this problem?
- A. Suction the patient every hour.
- B. Reposition the patient every 2 hours.
- C. Add additional water to the patient's enteral feedings.
- D. Instill 5 ml of sterile saline into the endotracheal tube (ET) before suctioning.
Correct Answer: C
Rationale: Because the patient's secretions are thick, better hydration is indicated. Suctioning every hour without any specific evidence for the need will increase the incidence of mucosal trauma and would not address the etiology of the ineffective airway clearance. Instillation of saline does not liquefy secretions and may decrease the SpO2. Repositioning the patient is appropriate but will not decrease the thickness of secretions.
The family members of a patient who has just been admitted to the intensive care unit (ICU) with multiple traumatic injuries have just arrived in the ICU waiting room. Which of the following actions should the nurse take first?
- A. Immediately take the family members to the patient's room.
- B. Discuss ICU visitation policies and encourage family visits.
- C. Describe the patient's injuries and the care that is being provided.
- D. Invite the family to participate in a multidisciplinary care conference.
Correct Answer: C
Rationale: Lack of information is a major source of anxiety for family members and should be addressed first. Family members should be prepared for the patient's appearance and the ICU environment before visiting the patient for the first time. ICU visiting should be individualized to each patient and family rather than being dictated by rigid visitation policies. Inviting the family to participate in a multidisciplinary conference is appropriate but should not be the initial action by the nurse.
The nurse is caring for a patient with a head injury intubated and placed on a mechanical ventilator. When monitoring the patient, which of the following findings should the nurse report to the health care provider?
- A. Oxygen saturation of 94%.
- B. Respirations of 18 breaths/minute.
- C. Green nasogastric tube drainage.
- D. Increased jugular venous distention.
Correct Answer: D
Rationale: Increases in JVD in a patient with head injury may indicate an increase in intra-cranial pressure (ICP) and that the PEEP setting is too high for this patient. A respiratory rate of 18, saturation of 94%, and green nasogastric tube drainage are normal.
