A patient is considered as having sufficient respiratory muscle strength to maintain adequate ventilation and prevent secretion retention when the maximum inspiratory pressure (MIP; NIF) is more negative than:
A. -5 cm H2OB. -10 cm H2OC. -15 cm H2OD. -20 cm H2O

Prior to intubation in an emergency, injection of air into the pilot line fails to inflate the cuff. You should
A. check the cuff for leaks
B. check the valve on the pilot lineC. replace the endotracheal tubeD. inspect the pilot line for patency

A patient is asked to inhale as deeply as possible and blow out all his air as hard as they can until empty. What test is being performed?
A. FVC
B. IC
C. TLC D. MVV

On inspection of an ECG rhythm strip from an adult patient, you note the following: rate of 150; regular rhythm; normal P waves, P-R intervals, and QRS complexes. The most likely problem is:
A. atrial flutter
B. sinus tachycardia
C. ventricular tachycardia D. atrial fibrillation

A patient is receiving ventilatory support after thoracic surgery. You measure the patient’s maximum inspiratory pressure (MIP/NIF) as -33 cm H2O. Based on this value, the patient has:
A. a need for continued ventilatory support
B. a large leak in their endotracheal tube cuff
C. a normal maximum inspiratory pressure
D. adequate muscle strength to consider weaning

Postural drainage would best be indicated for a patient with:A. pleural effusion
B. asthma
C. pneumoniaD. cystic fibrosis

Which of the following is associated with the administration of aerosolized epinephrine?
A. tachycardia
B. bradycardia
C. laryngospasmD. bronchospasm

A doctor orders a metered dose inhaler (MDI) bronchodilator for a patient receiving mechanical ventilation via a dual-limb breathing circuit. To maximize aerosol deposition, you would:
A. place the MDI directly in-line on the inspiratory side of the circuit
B. recommend that a small volume nebulizer be used instead of the MDI
C. place the MDI plus a spacer in-line on the inspiratory side of the circuit
D. place the MDI directly in-line on the expiratory side of the circuit

Any sudden occurrence of pulmonary or cardiac distress in older, bed-ridden patients and those having undergone extensive abdominal or pelvic surgery suggest a diagnosis of:
A. coronary artery disease
B. pulmonary thromboembolismC. anaphylactic shock
D. acute left ventricular failure

You would recommend against using noninvasive positive pressure ventilation (NPPV) for a patient with:
A. secretions requiring suctioningB. the need for moderate sedationC. facial burns or trauma
D. FIO2 needs greater than 40%

What two disease processes are closely linked with COPD?A. Emphysema and BronchiloitisB. Bronchiectasis and PneumoniaC. Emphysema and Chronic Bronchitis

All of the following are considered to be signs and symptoms of Emphysema EXCEPTA. Pink PufferB. CyanosisC. AnemiaD.Frequent Respiratory infections

Patients who fail a spontaneous breathing trial should be:A. Placed on a mode of ventilation that allows them to rest and recoverB. Placed on another spontaneous breathing trial in 24 hrs.C. Evaluated for factors that may have contributed to their failure.D. All of the above

A rapid shallow -breathing index (RSBI) is calculated by:A. Dividing the respiratory rate by the peak pressureB. Multiplying the peak pressure by the lung complianceC. Dividing the spontaneous respiratory rate by the spontaneous tidal volume D. Subtracting the plateau pressure from the peak pressure

When evaluating a PA film of the chest, you note that the right costophrenic angles are blunted. What does this suggest?A. PneumothoraxB. Presence of infiltrates in the right lower lobeC. Presence of atelectasis in the right baseD. Presence of pleural effusion on the right
