PFT Clinic II

Front

While reviewing the patient’s medical record, you note that the FEV1/FVC ratio is reported as being severely reduced. Which of the following is most consistent with this finding? Options: Pulmonary hypertension, Morbid obesity, Chronic asthma, Pneumonia

Back

Chronic asthma

Front

Upon the assessment of a patient receiving volume control AC ventilation, you observe a flow-volume loop with a sawtooth pattern on exhalation. Which action would help this patient the most? Options: Switch to pressure control ventilation, Administer a bronchodilator, Increase the endotracheal tube cuff pressure, Assess the patient’s need for suctioning

Back

Assess the patient’s need for suctioning

Front

The amount of gas that can be inhaled above the volume that is normally inhaled during quiet breathing is called what?

Back

IRV

Front

After reviewing your work order for the day, you notice that you have a patient with chronic bronchitis and another patient with emphysema. Which of the following PFT findings would you expect for these patients? Increased lung compliance, Decreased forced expiratory flows, Decreased total lung capacity, Decreased diffusing capacity

Back

Decreased forced expiratory flows

Front

Which pulmonary function test is being performed when the physician instructs the patient to “inhale as deeply as possible and then blow out all of the air as hard as you can”?

Back

FVC

Front

You have been monitoring the vital capacity and maximum inspiratory pressure readings over the last 4 hours of a 39-year-old female patient that is receiving mechanical ventilation. The values have steadily decreased over this time period. How should this be interpreted?

Back

Her condition is worsening

Front

What is the patient’s minute ventilation based on the following spirometry results? Respiratory rate = 19, Tidal volume = 380 mL, Dead space = 145 mL, Vital capacity = 1.1 L.

Back

7.2 L/min

Front

You are called to measure the strength of a patient’s respiratory muscles at the bedside. Which device would you select? Options: Pressure manometer, Peak flowmeter, Ergometer, Respirometer

Back

Pressure manometer

Front

Your patient has the following PFT results: Vital Capacity 54% of predicted, FEV1 76% of predicted, FEV1/FVC ratio 82%, Peak Flow 119% of predicted, Total Lung Capacity 65% of predicted. What is the best interpretation of the results? Options: Restrictive disease only, Obstructive disease only, Bronchitis, Mixed restrictive and obstructive disease

Back

Restrictive disease only

Front

What do the spirometry results indicate for a 52-year-old female patient whose FEV1 increased from 62% to 83% of predicted after a bronchodilator?

Back

The patient has a reversible airway obstruction.
