The head tilt-chin lift maneuver is contraindicated for patients who:

have a possible spinal injury

Blood tinged sputum can be caused by:

heart failure

Quiet tachypnea suggests possible:

shock

Atelectasis occurs when:

a deficiency of surfactant causes alveolar collapse

What is the most effective means of dislodging a mild airway obstruction in a patient?

Encourage the patient to forcefully cough

An oropharyngeal airway is contraindicated for patients with:

a gag reflex

You should reserve oxygen concentrations higher than what percentage for patients with hypoxia who do not respond to lower concentrations?

50%

To generate the optimal particle size, most nebulizers need to have a gas flow of at least:

6 L/min

Current guidelines from the American Heart Association state that supplemental oxygen is not indicated if the patient is not experiencing respiratory distress and their oxygen saturation is at least:

94%

Why are children more prone to croup when they acquire a viral infection than adults infected with the same virus?

A child's airway is narrower than an adult's, and even minor swelling can result in obstruction

A person who experiences sharp chest pain followed by increasing dyspnea after coughing likely has:

A pneumothorax

Which of the following is a disadvantage of the hand powered portable suction device?

Body fluid contact

A patient presents with a barrel chest, muscle wasting, and pursed-lip breathing. These symptoms are a sign of which condition?

Emphysema

Which medication causes smooth muscle relaxation and is used to treat severe asthma?

IV magnesium sulfate

What type of medication is montelukast(Singulair)?

Leukotriene blocker

How should you assess peak expiratory flow in a patient with asthma?

Place the patient in a seated position with legs dangling

Which of the following conditions is a general indication for using CPAP?

The patient is experiencing respiratory distress after a submersion incident

Normally, an adult at rest should have respirations that:

follow a regular pattern of inhalation and exhalation

The upper airway of an adult consists of all the structures above the:

glottis

When ventilating a patient with a BVM, you note increased compliance. This means that:

air can be forced into the lungs with relative ease

Negative pressure ventilation occurs when:

air is drawn into the lungs when intrathoracic pressure decreases

What type of medication can cause thick sputum?

antihistamine

A nonrebreathing mask is used to administer high-flow oxygen to significantly hypoxemic patients who:

are otherwise breathing normally

The main stem bronchus ends at the level of the:

bronchioles

The recovery position is indicated if the patient:

can maintain the airway spontaneously

The most common complaint in patients with a respiratory disease is:

dyspnea

Polycythemia is a condition in which:

excess red blood cells are produced in response to chronic hypoxia.

The body's immediate response to mild hypoxemia is:

increased heart rate

What is one of the primary advantages of using blind nasotracheal intubation

it does not require a laryngoscope

Paroxysmal nocturnal dyspnea may be a sign of:

left sided heart failure

In contrast to negative pressure ventilation, positive pressure ventilation:

may impair blood return to the heart

Difficulty with exhalation is MOST characteristic of:

obstructive lung disease

Pulse oximetry is used to measure the:

percentage of hemoglobin that is saturated with oxygen

Tenting of the skin under the jaw often occurs when airway devices are inadvertently inserted into the:

piriform fossae

If you suspect that an unconscious patient has experienced a spinal injury, you should open their airway by:

placing your fingers behind the angle of the jaw and lifting the jaw forward

Patients with pneumonia often experience a coughing fit when they roll from one side to the other becasue:

pneumonia often occurs in the lung bases, typically on one side

A patient's peripheral pulses become extremely weak during inhalation. This is called:

pulsus paradoxus

Cor pulmonale is defined as:

right-sided heart failure secondary to chronic lung disease

A patient with orthopnea:

seeks a sitting position when short of breath.

The fraction of inspired oxygen (FIO2) increases with:

supplemental oxygen
