A+
The EMT should assess a patient's tidal volume by?
A. observing for adequate chest rise
B. assessing the facial area for cyanosis
C. counting the patient's respiratory rate
D. measuring the patient's oxygen saturation - ANSWER: A. Observing for adequate
chest rise
Tidal volume- the volume of air that is moved in or out of lungs by single breath-
observed by adequate chest rise. If rise is shallow, tidal volume is likely reduced.
In an otherwise healthy individual, the primary stimulus to breath is a(n):
A. increased level of oxygen in the blood
B. decreased level of oxygen in the blood
C. increased level of carbon dioxide in blood
D. decreased level of carbon dioxide in blood - ANSWER: C. increased level of carbon
dioxide in blood
Under control of the brain stem, rising levels of carbon dioxide in the arterial blood
normally stimulate breathing in an otherwise healthy patient.
Signs of adequate breathing in the adult include all of the following, EXCEPT:
A. pink, warm, dry skin
B. shallow chest rise
C. symmetrical chest movement
D. a respiratory rate of 16 breaths/min - ANSWER: B. shallow chest rise
shallow chest rise= reduced tidal volume
During insertion of an oropharyngeal airway into an unconscious patient, she begins
to vomit. The first thing you should do is:
A. turn the patient on her side.
B. remove the airway at once.
C. suction the patient's mouth.
D. use a smaller-sized oral airway. - ANSWER: A. turn the patient on their side
allows vomit to drain
In which of the following patients would a nasopharyngeal airway be
contraindicated?
A. a semiconscious patient with a gag reflex
B. an unconscious patient with an intact gag reflex
C. a patient who fell 20 feet and lander on their head
,D. an unconscious patient who gags when you insert an oral airway - ANSWER: C. a
patient who fell 20 feet and lander on their head
contraindication with patients with severe head or facial injuries
You are delivering oxygen to a patient with a nasal cannula at 4L/min when he
begins to complain of a burning sensation in his nose. You should:
A. remove the nasal cannula
B. apply a nonrebreathing masks
C. attach oxygen humidifier
D. increase the flow rate to 6 L/min - ANSWER: C. attach an oxygen humidifier
administering "dry" oxygen especially over a prolonged period can results in drying
of nasal membranes
A patient is found unconscious after falling from a third floor window. His
respirations are slow and irregular. You should:
A. place him in the recovery position
B. apply oxygen via a nonrebreathing mask
C. suction his airway for up to 15 seconds
D. assist his breathing with a bag-valve mask device - ANSWER: D. assist his breathing
with a bag-valve mask device
slow/irregular breaths= inadequate oxygen
When ventilating an apneic adult with a simple barrier device, you should squeeze
the bag:
A. until its empty
B. over a period of 2 seconds
C. at a rate of 20 breaths/min
D. until visible chest rise is noted - ANSWER: D. until visible chest rise is noted
You and your partner are ventilating an apneic adult when you notice that is
stomach is becoming distended. You should:
A. suction his airy for up to 15 seconds
B. reposition his head
C. increase the rate and volume
D. decreased ventilation rate but increase the volume - ANSWER: B. reposition his
head
gastric distention occurs when air enters the stomach
You are managing a 62yr old who complains of crushing chest pain. Her BP is 84/64
with HR of 110. Medical control advises you to assist in her taking her prescribed
nitroglycerin. You should:
A. reassess the HR then assisted with nitro
B. repeat the BP to DR and confirm order
C. wait 10 mins, reassess BP, then give nitro
D. administer the nitro and reassess BP - ANSWER: B. Repeat the BP to DR and
confirm order
, Nitroglycerin is a vasodilator and lowers BP, contraindication in BP <100
Activated charcoal is indicated for patients who ingested certain drugs/toxins
because it:
A. acts as direct reversal agent for most meds
B. induces vomiting
C. detoxifies the drug before it can cause harm
D. binds the chemicals in stomach and delays absorption - ANSWER: D. Binds to the
chemicals in the stomach and delays absorption
activated charcoal=an adsorbent
With regard to pharmacology, the term "action" refers to the:
A. ability of drug to cause harm
B. ability of drug to produce side effects
C. amount of time it will take the drug to work
D. expected effect of drug on the patient's body - ANSWER: D. expected effect of
drug on the patient's body
Which patient is the BEST candidate for oral glucose?
A. a conscious patient who is showing signs of hypoglycemia
B. an unconscious diabetic
C. conscious diabetic with suspected hyperglycemia
D. a semiconscious patient with signs/symptoms of low BG - ANSWER: A. a conscious
patient who is showing signs of hypoglycemia
Epi is given to patients with anaphylactic shock because of its effects of:
A. bronchodilation and vasodilation
B. bronchodilation and vasoconstriction
C. vasodilation and bronchoconstriction
D. bronchoconstriction and vasoconstriction - ANSWER: B. bronchodilation and
vasoconstriction
anaphylactic shock= bronchoconstriction and vasodilation
A diabetic patient has polydipsia. This means:
A. is excessively thirsty
B. urinates frequently
C. has low blood sugar
D. is unable to swallow - ANSWER: A. is excessively thirsty
After applying a tourniquet, the injury from a patient's leg stops bleeding. This is
called:
A. hemolysis
B. hemiplegia
C. hemostasis
D. hematemesis - ANSWER: C. hemostasis
Enlargement of the liver is called:
