Question 1

Which postural drainage position is used to drain the right middle lobe of the lung?

Accepted Answer

Left side-lying with foot of bed elevated 15°

Answer

The right middle lobe drains best with the patient in left side-lying with the foot of the bed elevated 15° to use gravity assistance.

Question 2

FEV1/FVC ratio below 0.70 is indicative of which type of pulmonary dysfunction?

Accepted Answer

Obstructive lung disease

Answer

An FEV1/FVC ratio <0.70 confirms airflow obstruction, as seen in COPD and asthma, where expiration is disproportionately impaired.

Question 3

Which technique involves applying rhythmic compression to the chest wall during exhalation to mobilize secretions?

Accepted Answer

Vibration

Answer

Chest vibration applies fine oscillatory force during exhalation to loosen and mobilize bronchial secretions toward larger airways.

Question 4

A patient's resting heart rate is 95 bpm and target training zone is 60–80% of heart rate reserve using the Karvonen formula. If their maximum HR is 170 bpm, what is the lower training HR?

Accepted Answer

132 bpm

Answer

HRR = 170 − 95 = 75; lower target = 95 + (0.60 × 75) = 95 + 45 = 140 bpm — wait, let me recalculate: 95 + 45 = 140... actually 95 + 0.60×75 = 95+45=140. The correct answer is 140 bpm (option B).

Question 5

Diaphragmatic breathing exercises are prescribed primarily to:

Accepted Answer

Improve efficiency of ventilation by maximizing diaphragm use

Answer

Diaphragmatic breathing reduces the use of accessory muscles, improves ventilatory efficiency, and reduces the work of breathing.
