What does the nurse know is the major objective of performing cardiopulmonary resuscitation (CPR) in a cardiac arrest patient?
To provide breathing until an automated external defibrillator (AED) arrives
To provide oxygen to the brain, heart and other vital organs
To restore cardiac output to normal
To prevent brain death within 2 minutes of anoxia
The Correct Answer is B
A. To provide breathing until an automated external defibrillator (AED) arrives: While providing ventilation is part of CPR, the primary goal is not simply to bridge time until defibrillation. Ventilation alone does not ensure adequate perfusion of vital organs in cardiac arrest.
B. To provide oxygen to the brain, heart and other vital organs: The major objective of CPR is to maintain circulation and oxygen delivery to vital organs, particularly the brain and heart, until spontaneous cardiac activity can be restored. Effective chest compressions sustain perfusion, minimizing ischemic injury and improving the chance of survival with intact neurologic function.
C. To restore cardiac output to normal: CPR does not immediately restore normal cardiac output; it provides partial perfusion to vital organs. Full restoration of cardiac output requires successful return of spontaneous circulation through defibrillation, medications, and advanced cardiac life support interventions.
D. To prevent brain death within 2 minutes of anoxia: Although timely CPR reduces the risk of brain injury, brain death prevention is an indirect outcome rather than the immediate objective. The critical focus is maintaining oxygenated blood flow to vital tissues until cardiac function can resume.

Correct Answer is ["B","D","E"]
Explanation
A. Maintain head of bed elevation at 15 degrees or less: For a patient with increased intracranial pressure (ICP), the head of the bed should typically be elevated 30 degrees, not limited to 15 degrees. Proper elevation promotes venous drainage from the brain and helps reduce ICP, making 15 degrees insufficient for effective ICP management.
B. Provide oxygen therapy to maintain oxygen saturation above 92: Maintaining adequate oxygenation is critical in patients with neurological injury. Hypoxia can worsen cerebral ischemia and increase ICP, so oxygen therapy should be titrated to keep SpO₂ within the prescribed safe range, typically above 92%, to support cerebral perfusion and prevent secondary brain injury.
C. Keep lights dim in client's room to accommodate photophobia: While dim lighting can increase comfort in patients with migraine or photophobia, it does not directly affect ICP management. This action is supportive but not a priority intervention in caring for a patient with increased ICP.
D. Assess the client for headaches and behavior changes frequently: Frequent neurological assessment, including monitoring for changes in level of consciousness, behavior, and headache, is essential for early detection of worsening ICP or complications. These assessments guide timely interventions and are critical in intensive care management of post-stroke patients.
E. Minimize suctioning or hyper-oxygenate client before suctioning: Suctioning can stimulate coughing and increase ICP. To prevent sudden spikes in ICP, suctioning should be minimized and performed only when necessary, with pre-oxygenation to maintain cerebral oxygenation and reduce secondary brain injury risk.
Correct Answer is D
Explanation
Calculation:
- Convert patient weight from pounds to kilograms
Weight = 158 ÷ 2.2
= 71.818 kg
- Determine norepinephrine concentration in mcg/mL
4 mg in 250 mL = 4000 mcg ÷ 250 Ml
= 16 mcg/mL
- Calculate the infusion rate in mL/min
Infusion rate = 18 mL/hr = 18 ÷ 60
= 0.3 mL/min
- Calculate norepinephrine dose in mcg/min
Dose in mcg/min = 0.3 × 16
= 4.8 mcg/min
- Calculate dose in mcg/kg/min
Dose = 4.8 ÷ 71.818
= 0.0669 mcg/kg/min
- Round to thousandths
= 0.067 mcg/kg/min
