N125 Study Guide and Questions
Solved 100% Correct |Verified Answers
Factors influencing capacity of blood to carry oxygen - ANSWER 1) dissolved oxygen
in plasma
2) hemoglobin
3) tendency of hemoglobin to bind to oxygen
Carbon Dioxide Transport - ANSWER diffuses red blood cells and is hydrated into
carbonic acid
Tachypnea - ANSWER rapid respirations
Bradypnea - ANSWER abnormally slow respiratory rate
Apnea - ANSWER no breathing
Orthopenea - ANSWER sitting upright and standing makes it easier to breath
Dyspnea - ANSWER difficulty breathing or shortness of breath
,Kussamaul - ANSWER deep, labored, rapid respirations to compensate for acidic pH
by decreasing CO2 levels
Cheyne-Stokes Respirations - ANSWER - rhythmic waxing and waning followed
by periods of apnea
- seen when there is a decreased blood flow or injury to brain stem
Biot's (Cluster) - ANSWER shallow breaths interrupted by apnea
Hypoxia - ANSWER - decreased oxygen levels in tissue
- results from deficiency in oxygen delivery or oxygen use at a cellular level
Cause of Hypoxia - ANSWER 1) decreased hemoglobin level and lowered oxygen
carrying capacity of blood
2) diminished concentration of inspired oxygen at high altitudes
3) inability of tissue to extract oxygen from the blood (cyanide poisoning)
4) decreased diffusion of oxygen from alveoli to blood (pneumonia)
5) poor tissue perfusion with oxygenated blood (shock)
6) impaired ventilation (chest trauma)
Hypoxemia - ANSWER decreased oxygen levels in blood
Cyanosis - ANSWER bluish discoloration of skin, nail beds, and mucous membranes
Cause of Cyanosis - ANSWER presence of desaturated hemoglobin in capillaries
, Respiratory Lifestyle Risk Factors - ANSWER - nutrition
- exercise
- smoking
- substance abuse
- stress
Coughing - ANSWER helps maintain a clear airway and remove secretions from
upper and lower airways
Deep Inhalation - ANSWER - increases lung volume and airway diameter
- allows air to pass through partially obstructed mucus
Deep Breathing - ANSWER increases air to lower lungs and opens the pores of
Kohn between alveoli to allow sharing of oxygen between alveoli
Nursing measures to promote respiratory function - ANSWER 1) coughing and
deep breathing techniques
2) hydration
3) encourage ambulation
4) promote comfort
5) medication (bronchodilators)
6) incentive spirometer
7) positioning
Incentive Spirometer - ANSWER helps patients who aren't ambulating ventilate lungs
