NU 455 Exam 1 Questions and
Answers 100% PASS
Type I Respiratory Failure Hypoxia defined as - CORRECT ANSWER-O2 less
than 50
Type I Respiratory Failure Hypoxia Assessment Findings - CORRECT ANSWER-
increased pulse (try to circulate RBC), increased respiratory rate, restless, anxious,
diaphoresis, agitated (decreased O2 to brain) late: cyanosis, mental status changes
Type I Respiratory Failure Hypoxia is found in - CORRECT ANSWER-
pneumonia, ARDS, pneumothorax, PE, pulmonary edema, drowning, bleeding,
tumor, trauma
Type II Respiratory Failure Hypercarbia is defined as - CORRECT ANSWER-
CO2 more than 50
Type II Respiratory Failure Hypercarbia assessment findings - CORRECT
ANSWER-lethargic, decreased respiratory rate, difficulty focusing, tired, less
responsive, decreased respiratory drive (neuro symptoms of increased CO2)
Type II Respiratory Failure Hypercarbia found in - CORRECT ANSWER-CNS
depression, drug overdose, asthma, COPD, chest wall abnormalities/trauma,
neuromuscular disease (Myasthenia Gravis, Guilian-Barre)
,normal pH level - CORRECT ANSWER-7.35-7.45
normal PaO2 level - CORRECT ANSWER-80-100
normal spO2 - CORRECT ANSWER-over 92%
normal paCO2 - CORRECT ANSWER-35-45
normal HCO3 - CORRECT ANSWER-22-26
respiratory acidosis is defined as - CORRECT ANSWER-carbon dioxide excess;
pH under 7.35 and pCO2 over 45
respiratory acidosis found in - CORRECT ANSWER-COPD, pneumonia, ARDS
respiratory acidosis nursing interventions - CORRECT ANSWER-- Treat
underlying cause (PE, aspiration, atelectasis, pneumothorax, overdose of sedatives)
- Improving ventilation
- Adequate hydration to help secrete mucus
- Semi fowlers position
- Raise PaCO2 slowly or else the kidneys will not be able to get rid of the bicarb in
time so now the patient will be in alkalosis and have a seizure
- Meds
-- Bronchodilators reduce bronchospasm

, -- Antibiotics for respiratory infections
-- Thrombolytics or anticoagulants for PEing
respiratory acidosis clinical manifestations - CORRECT ANSWER-headache,
decreased LOC, hypoventilation (cause of problem), cardiac dysrhythmias, if
severe: hypotension
respiratory alkalosis is defined as - CORRECT ANSWER-carbon dioxide deficit;
pH over 7.45 and CO2 under 35
respiratory alkalosis nursing interventions - CORRECT ANSWER-- Treat
underlying cause
- If anxiety instruct patient to breathe slowly or into a bag, it will help accumulate
CO2, antianxiety if extreme
- If wrong vent setting, decrease respiration rate
respiratory alkalosis found in - CORRECT ANSWER-extreme anxiety, hypoxemia,
early phase of salicylate intoxication, gram-negative bacteria, wrong vent settings
respiratory alkalosis clinical manifestations - CORRECT ANSWER-- headache,
tingling, dizziness
- hyperventilation (cause of problem), Excitation and belligerence, lightheadedness,
unusual behaviors, followed by decreased LOC if severe, Periorbital and digital
paresthesia, carpopedal spasm, tetany, Diaphoresis, Cardiac dysrhythmias
