Tech Prep Respiratory System

How does the respiratory system work to maintain homeostasis in the body?

• By regulating blood pressure

• By filtering waste from the blood

• By controlling blood pH through CO2 removal

• By producing hormones

Which of the following best explains why carbon monoxide (CO) is dangerous?

• It increases the production of bicarbonate ions.

• It damages the alveoli.

• It binds more readily to hemoglobin than oxygen does, reducing oxygen delivery to tissues.

• It causes the diaphragm to spasm.

A respiratory therapist is adjusting the oxygen flow rate for a patient with hypoxemia. What is hypoxemia?

• Low oxygen levels in the blood

• High carbon dioxide levels in the blood

• Fluid accumulation in the lungs

• Inflammation of the bronchioles

A patient is experiencing rapid, shallow breathing. Which of the following is the most likely cause?

• Increased tidal volume

• Decreased CO2 levels in the blood

• Reduced lung capacity or increased resistance to airflow

• Increased oxygen binding to hemoglobin

In a medical emergency, why is identifying the cricoid cartilage important?

• It is the site of oxygen exchange.

• It protects the vocal cords.

• It is the landmark for performing a tracheostomy.

• It regulates airflow into the lungs.

A firefighter enters a smoke-filled building. What change occurs in their trachea over time?

• The ciliated epithelium increases in number.

• The ciliated epithelium is replaced by non-ciliated squamous epithelium.

• The cartilage rings thicken.

• The trachea narrows.

A patient with emphysema has damaged alveoli. How does this damage affect gas exchange in the lungs?

• It increases the efficiency of oxygen uptake.

• It has no effect on gas exchange.

• It decreases the surface area available for oxygen and carbon dioxide exchange.

• It causes an increase in surfactant production.

During a surgical procedure, why is it critical for the anesthesiologist to monitor the patient's respiratory function?

• To ensure adequate oxygen delivery and CO2 removal

• To prevent damage to the nasal cavity

• To measure the patient's tidal volume

• To regulate the patient's heart rate

A doctor is explaining tidal volume to a patient. Which of the following best describes what the doctor would say?

• Tidal volume is the amount of air you can forcefully exhale after taking a deep breath.

• Tidal volume is the total amount of air your lungs can hold.

• Tidal volume is the normal amount of air you breathe in and out with each breath.

• Tidal volume is the air left in your lungs after you breathe out as much as possible.
