Hallmark STUDY ISB BSN 206 (Latest Update 2025 / 2026) Questions with Verified Answers | 100% Correct | Grade A - Nightingale T/F: Ventilation is the exchange of oxygen for carbon dioxide at the cellular level.
- ANSWER False
Diffusion is the exchange of oxygen for carbon dioxide at the cellular level Ventilation is the process of moving respiratory gases into and out of the lungs
T/F: A severely anemic patient may experience tachypnea during routine daily
activities. - ANSWER True.Reduced hemoglobin levels result in reduced oxygen-carrying capacity that leads to decreased oxygen saturation. The body compensates by increasing the respiratory rate What are signs & symptoms of hypoxia (low cellular and tissue oxygen) - ANSWER restlessness (early sign of hypoxia) irritability anxiety confusion/disorientation Decreased ability to concentrate Aletered level of consciousness Syncope Altered behavior increased pulse rate (tachycardia) increased respiratory rate (tachypnea) Elevated BP Cardiac dysrhythmias (irregular/and or premature rhythms) 1 / 3
Pallor Complaints of dyspnea (breathlessness) Cyanosis (usually a late sign of hypoxia) What causes hypoxia? - ANSWER Inadequate tissue oxygen w/ adequate blood supply Develops from a deficiency in oxygen delivery or oxygen utilization at the cellular level T/F: A patient with a "normal" respiratory rate cannot become hypoxic - ANSWER False.An individula can have a normal ventilation rate and be unable to absorb enough oxygen to sustain normal tissue and organ function T/F: The appearance of cyanosis around the lips and fingertips of the patient may be the result of chronic respiratory impairment. - ANSWER True.Cyanosis, a bluish discoloration of the skin or mucous membranes, is caused by inadequate oxygenation of the bloodstream. Patients with chronic lung diseases (COPD) may exhibit cyanosis.T/F: An elevated pulse rate is the body's attempt to increase oxygen delivery to the tissues. - ANSWER True.An increase in pulse rate is an adaptive response to meet the body's oxygen demand. The increased pulse rate may occur in conjunction with an increased respiratory rate that attempts to increase oxygen supply.What are the 3 cough types? - ANSWER Huff; Cascade; Quad 2 / 3
Which type of cough stimulates the natural cough reflex and is helpful in clearing the large central airways such as the tracheobronchial tree.? - ANSWER Huff cough
T/F: A patient with an acute onset of pneumonia is coughing copious amounts of
secretions. The best coughing technique to teach a patient is the huff cough - ANSWER False The best coughing technique for large volumes of sputum is the cascade cough.
T/F: Coughing maintains patency of the airway by removing secretions and/or
foreign body materials. - ANSWER True.Coughing is a protective mechanism that assists in maintaining airway patency.Assisting a patient, a paraplegic patient w/ bronchitis, by supporting his abdominal muscles during forced expiration and coughing is an example of huff coughing. - ANSWER False.this is an example of quad coughing.The quad cough is used w/ patients who lack control of their abdominal muscles (patients w/ spinal cord injuries and patienst w/ recent abdominal surgery) T/F: Patients at risk for airway obstruction should be encountered to breathe deeply and cough at least once every 4 hours. - ANSWER False.Patients at risk for airway obstruction should be encouraged to cough at least every hour.
