ChatGPT Final Exam Flashcards
Define hypoxia.
Low oxygen in the tissues and cells.
Define hypoxemia.
Low oxygen concentration in the arterial blood.
What is atelectasis?
Collapse of alveoli, reducing gas exchange.
What does FiO₂ measure?
Fraction of inspired oxygen (e.g., 1.0 = 100%).
What is SpO₂?
Oxygen saturation measured by pulse oximetry.
What is PaO₂?
Tension of oxygen in arterial plasma.
What are retractions?
Inward pulling of soft tissues with breathing—sign of respiratory distress.
What is cyanosis?
Bluish discoloration due to hypoxia.
Early signs of hypoxia in children?
Restlessness, tachypnea, nasal flaring.
Late signs of hypoxia?
Cyanosis, bradycardia, altered mental status.
What is RSV?
Respiratory Syncytial Virus, a common pediatric virus causing bronchiolitis.
Who is most at risk for severe RSV?
Infants <6 months, premature babies, congenital heart disease.
Common RSV symptoms?
Coughing, wheezing, nasal congestion, poor feeding.
Main treatment focus for RSV?
Supportive care: suctioning, oxygen, fluids.
Why avoid antibiotics in RSV?
RSV is viral, not bacterial.
What is the purpose of nasal suctioning in RSV?
To clear secretions and improve breathing.
When should a child with RSV go to the ER?
Signs of respiratory distress, cyanosis, dehydration.
What is the normal SpO₂ target range in pediatrics?
≥ 95% on room air.
Key nursing priority in RSV?
Maintain airway patency.
What PPE is used for RSV isolation?
Contact and droplet precautions (gown, gloves, mask).
What is schizophrenia?
A chronic brain disorder affecting <1% of the U.S. population, with symptoms like delusions, hallucinations, and disorganized speech.
What percentage of schizophrenia risk is genetic?
Approximately 80%.
List 3 neurotransmitters involved in schizophrenia.
Dopamine, serotonin, glutamate.
Name 3 brain-related risk factors for schizophrenia.
Brain abnormalities, neurotransmitter imbalances, genetic predisposition.
