What function do the nasal turbinates serve?

Warming and humidifying inhaled air

A pt who's experiencing an allergic reaction states that his tongue "feels thick" and speaks at low volume. You should quickly evaluate for:

Angioedema

Common effects of gag reflex stimulation include all of the following, EXCEPT:

Tachycardia

The most obvious external landmark of the larynx is the:

Thyroid cartilage

Wheezing is resolved with medications that:

Relax the smooth muscle of the bronchioles

Hypoventilating patients:

Become hypercapneic and acidotic

A patient with orthopnea:

Seeks a sitting position when short of breath

Digital clubbing is MOST indicative of:

Chronic hypoxia

The diaphragm of the stethoscope is designed to auscultate:

High-pitched sounds

Which of the following conditions would LEAST likely present with an acute onset of respiratory distress?

Pneumonia

Frothy sputum that has a pink tinge to it is MOST suggestive of:

Congestive heart failure

A pulse oximetry reading would be LEAST accurate in a patient:

with poor peripheral perfusion

If a colormetric ETCO2 detector turns purple during the exhalation phase through an ET tube, approx. how much cO2 is being exhaled?

Less than 0.5%

A sudden increase in end-tidal cO2 may be the earliest indicator of:

Return of spontaneous circulation

Pneumonitis is especially common in older patients with:

Chronic food aspiration

COPD is characterized by:

Changes in pulmonary structure and function that are progressive and irreversible

A patient with status asthmaticus commonly presents with:

Physical exhaustion and inaudible breath sounds

A hyperventilating patient:

may be acidotic and is trying to increase his or her pH level

Intubation of a patient with severe asthma:

is often a last resort because asthmatics are difficult to ventilate and are prone to pneumothoraces

66 yr old pt - has bronchitis w/ resp. distress - takes meds for hi BP, recently took an over the counter antitussive - no o2 response...

recent antitussive use

What valves opening and closing are behind "LUB - DUB?"

LUB: tricuspid & mitral valves CLOSE / Pulmonary & aortic valves OPEN - DUB: Pulmonary & aortic valves CLOSE /Tricuspid & mitral valves OPEN

29 yr old, severe asthma - has breathing tube - has taken 3 puffs from inhaler already, no effect - anxious/restless/tachypneic/wheezing...

you should apply a CPAP, transport immediately, and attempt to establish vascular access en route to the hospital

Morbidly obese pt - diff. breathing lying supine in bed - history of hypertension...

Sit him up or place him on his side

21 yr old - pleuritic chest pain/dyspnea - o2 sat of 93%, diminished breath sounds in upper right lobe...

Administer high flow o2 and transport at once

pt w/ emphysema - shortness of breath - on hi-flow o2 already - has IV - monitor shows sinus tach - spo2 89% - resp rate/depth decrease...

begin assisting his ventilations with a bag-mask and 100% oxygen

COPD pt w/ peripheral edema - pt conscious but agitated - breathing w/ slight diff. - adequate tidal vol. - has JVD when you push RUQ...

suspect acute right heart failure and administer oxygen

36 yr old - hist. of asthma, has severe resp. distress - nebulized but poor resp. inhibits it - mental status deterorating...

assist his ventilations and establish vascular access

middle-aged pt on CPAP - severe pulmonary edema - IV in place - tachypneic - o2 sat of 90% - reassess shows increased resp. but 84%...

remove the CPAP, assist his ventilations with a bag-mask device, and prepare to intubate

heroin abuser - found unconscious - resp. slow and shallow - pulse slow and weak...

assist ventilations with a bag-mask device, administer naloxone, and reassess his ventilatory status

pt has diff. breathing, sitting in tripod position - dyspneic/tachypneic - had sharp pain to left side of chest - denies any past hx...

acute pulmonary embolism

severe COPD pt - emaciated - on o2 via nasal cannula - semiconscious - breathing inadequately - daughter says there's DNR but not shown...

recognize that he is experiencing end-stage COPD, begin assisting his ventilations, and contact medical control as needed

One of the hallmarks of a pulmonary embolism is:

cyanosis that does not resolve with oxygen therapy

Bedridden patients w/ excessive pulmonary secretions are MOST prone to developing:

pneumonia

Patients with obvious respiratory failure require immediate:

ventilation support

Pickwickian syndrome is a condition in which respiratory compromise results from:

extreme obesity

Emphysema is caused by:

chronic destruction of the alveolar walls

When administering a nebulized bronchodilator, the oxygen flow rate should be set to at least ____ liters per minute:
