emergency call; determining scene safety, taking BSI precautions, noting the mechanism of injury or patient’s nature of illness, determining the number of patients, and deciding what, if any additional resources are needed including Advanced Life Support.

Abbreviation: TACO, transfusion-associated circulatory overload.

Which of the following statement regarding the hypoxic drive is correct?
Which of the following statements regarding the hypoxic drive is MOST correct? … The hypoxic drive stimulates a person to breathe on the basis of low oxygen levels. The hypoxic drive stimulates a person to breathe on the basis of low oxygen levels.
Which of the following is not part of the respiratory system?
The esophagus is part of the digestive system. The air will initially enter the nose, then proceed to the nasal cavity, to the pharynx, to the trachea, to the bronchioles, and to the lungs. The esophagus is part of the digestive system, not the respiratory system.
Which is the most appropriate method to use when moving a patient from his or her bed to a wheelchair?
Use your legs to lift. At the same time, the patient should place their hands by their sides and help push off the bed. The patient should help support their weight on their good leg during the transfer. Pivot towards the wheelchair, moving your feet so your back is aligned with your hips.
What is hypoxic respiratory drive?
The hypoxic drive is a form of respiratory drive in which the body uses oxygen chemoreceptors instead of carbon dioxide receptors to regulate the respiratory cycle.
Why is Auscultating the lungs important?
Side-to-side comparison is most important when auscultating the chest. Listen to at least one full respiration in each location. When auscultating the lungs of an adult patient, the nurse notes that over the posterior lower lobes low-pitched, soft breath sounds are heard, with inspiration being longer than expiration.
What position is a patient with chest pain or discomfort or difficulty breathing without hypotension placed?
So the best transporting position for patients with respiratory distress or shortness of breath would therefore be the full Fowler’s (sitting upright) position.
Which of the following statements regarding normal gas exchange in the lungs is correct?
Which of the following statements regarding normal gas exchange in the lungs is correct: the actual exchange of oxygen and carbon dioxide occurs in the capillaries, blood that returns to the lungs from the body has low levels of carbon dioxide, the oxygen content in aveoli is highest during the exhalation phase, oxygen …
What is hypoxic drive and how does it affect patient care?
Hypoxia induces a breathing pattern of rapid and shallow breaths with a relatively higher increase in respiratory rate than tidal volume. The aim is to decrease the cost of breathing by avoiding the need to overcome the lungs’ higher elastance at high volumes.
Why do COPD patients rely on hypoxic drive?
“The hypoxic drive theory states that some patients with COPD develop chronically elevated arterial CO2 levels, and as a result, their hypercapnic drive becomes blunted, causing them to use their hypoxic drive to breathe instead,” Bottrell said.
Which of the following statements best describes the exchange of gases in the alveoli?
Which of the following statements BEST describes the exchange of gas in the alveoli? Air moves into the alveoli, blood is transported by the pulmonary capillaries, and diffusion occurs. The movement of oxygen and carbon dioxide between the alveoli and circulating blood is called: External respiration.
Which of the following patient should you place in the recovery position?
If a person is unconscious but is breathing and has no other life-threatening conditions, they should be placed in the recovery position. Putting someone in the recovery position will keep their airway clear and open. It also ensures that any vomit or fluid won’t cause them to choke.
When should Auscultating the lungs occur?
Using the diaphragm of the stethoscope, start auscultation anteriorly at the apices, and move downward till no breath sound is appreciated. Next, listen to the back, starting at the apices and moving downward. At least one complete respiratory cycle should be heard at each site.
What is the correct order of air flow from the nose to the alveoli in the lungs?
Pathway of air: nasal cavities (or oral cavity) > pharynx > trachea > primary bronchi (right & left) > secondary bronchi > tertiary bronchi > bronchioles > alveoli (site of gas exchange)
Where in the respiratory system does gas exchange occur?
ALVEOLI are the very small air sacs where the exchange of oxygen and carbon dioxide takes place. CAPILLARIES are blood vessels in the walls of the alveoli.
