Respiratory Therapy Exam

What is the key element to being successful on the TMC exam?

• Having a good knowledge base in respiratory therapy

• Knowing how to dissect practice exam questions

• Having test-taking skills

• All of the above

What is the purpose of pressure control in mechanical ventilation?

• To control the patient's respiratory rate

• To control the patient's tidal volume

• To control the patient's inspiratory pressure

• To control the patient's PEEP level

What is the significance of a patient being sedated and paralyzed in this scenario?

• It indicates a poor compliance in the patient

• It suggests the patient is in ARDS

• It allows for better control of ventilation parameters

• It increases the risk of pneumothorax

What is the purpose of inverse ratio ventilation (IRV)?

• To increase the patient's inspiratory time

• To decrease the patient's inspiratory time

• To increase the patient's expiratory time

• To decrease the patient's expiratory time

What changes in ventilator parameters would you expect to find when a pneumothorax occurs?

• Increase in peak inspiratory pressure (PIP) and plateau pressure (Pplat)

• Decrease in PIP and Pplat

• Increase in tidal volume

• Increase in respiratory rate

What is the purpose of an inspiratory hold in assessing plateau pressure?

• To measure the patient's tidal volume

• To measure the patient's inspiratory pressure

• To measure the patient's expiratory pressure

• To measure the patient's plateau pressure

What is the appropriate treatment for a tension pneumothorax?

• Insertion of a chest tube

• Administration of antibiotics

• Needle decompression

• Increase in PEEP level

What happens to pulmonary compliance when a pneumothorax occurs?

• It increases

• It decreases

• It remains unchanged

• It depends on the patient's age

What is the effect of pressure control ventilation on tidal volume?

• Tidal volume increases

• Tidal volume decreases

• Tidal volume remains unchanged

• Tidal volume varies based on compliance

Why is the respiratory rate set at 15 for a paralyzed patient?

• To prevent hyperventilation

• To maintain a normal breathing pattern

• To synchronize with the patient's natural respiratory rate

• To prevent the patient from initiating inspiratory efforts
