Blood tinged sputum can be caused by:
heart failure
Quiet tachypnea suggests possible:

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:

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?

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
