Question 1

An intense headache is associated most closely with:&#10;A)adrenal insufficiency&#10;B)cerebrovascular accident&#10;C)myocardial infarction&#10;D)postural hypotension

Accepted Answer

An intense headache can be a symptom of a cerebrovascular accident or stroke, which occurs when blood supply to the brain is interrupted. Adrenal insufficiency, myocardial infarction, and postural hypotension are not typically associated with intense headaches.

Question 2

In most cases of unconsciousness,the heart rate ___________ baseline level,while the blood pressure __________.&#10;A)rises above;increases&#10;B)rises above;decreases&#10;C)falls below;increases&#10;D)falls below;decreases

Accepted Answer

In most cases of unconsciousness, the heart rate often rises above the baseline level as the body attempts to maintain blood flow to the brain, while the blood pressure may decrease due to the underlying cause of the unconsciousness, such as shock or circulatory failure.

Question 3

An EMT,knowing neither the victim nor the medical history,will administer which of the following drugs in the field to an unconscious,but breathing,victim who does not respond to positioning,airway,and the administration of oxygen?

A)epinephrine
B)diazepam
C)diphenhydramine
D)50% dextrose
E)none of the above

50% dextrose

Accepted Answer

50% dextrose is administered in the field to an unconscious but breathing victim by an EMT when the victim's medical history is unknown, as it can quickly raise blood sugar levels in cases of suspected hypoglycemia, which is a common and treatable cause of unconsciousness.

Question 4

All of the following are methods of elevating blood pressure except:&#10;A)administration of IV vasopressor&#10;B)placing the patient in a semi-erect position (45 degrees upward tilt)&#10;C)terminating anesthesia and administering 100% oxygen&#10;D)intravenous fluid administration

Accepted Answer

Placing the patient in a semi-erect position (45 degrees upward tilt) can actually lower blood pressure by promoting venous return to the heart and can be used to manage high blood pressure, not elevate it. The other options, such as administering IV vasopressors, terminating anesthesia and administering 100% oxygen, and intravenous fluid administration, are direct interventions to increase blood pressure.

Question 5

Which of the following problems does the following describe: cold and wet to the touch,mild tremor of extremities,mentally confused?&#10;A)hypothyroidism&#10;B)hyperthyroidism&#10;C)acute adrenal insufficiency&#10;D)hypoglycemia&#10;E)hyperglycemia

Accepted Answer

The symptoms described are indicative of hypoglycemia, which can cause cold and clammy skin, tremors, and mental confusion due to low blood sugar levels.

Question 6

Restlessness,pallor,clammy skin,nausea,and vomiting may be signs of:&#10;A)vasodepressor syncope&#10;B)adrenal insufficiency&#10;C)myocardial infarction&#10;D)A,B,and C&#10;E)A and C

Accepted Answer

These symptoms can be indicative of vasodepressor syncope, adrenal insufficiency, and myocardial infarction, as they are common signs of distress in the body that can be associated with these conditions.

Question 7

Which of the following situations of unconsciousness will most likely involve hospitalization?&#10;A)vasodepressor syncope&#10;B)postural hypotension&#10;C)acute adrenal insufficiency&#10;D)A and C

Accepted Answer

Acute adrenal insufficiency is a potentially life-threatening condition that requires immediate medical attention and likely hospitalization to manage the symptoms and underlying causes. Vasodepressor syncope and postural hypotension, while they can cause unconsciousness, are generally less severe and often managed with lifestyle adjustments or outpatient care.

Question 8

Which of the following is most helpful in distinguishing vasovagal syncope from postural hypotension?&#10;A)heart rate&#10;B)respiratory rate&#10;C)body temperature&#10;D)mental status&#10;E)blood pressure

Accepted Answer

The answer of Which of the following is most helpful...

Question 9

In vasodepressor syncope,the heart rate ___________ baseline level,while the blood pressure __________.&#10;A)rises above;increases&#10;B)rises above;decreases&#10;C)falls below;increases&#10;D)falls below;decreases

Accepted Answer

In vasodepressor syncope, there is a sudden drop in blood pressure, which causes the heart to slow down and the blood vessels to dilate. This results in a decrease in blood pressure below the baseline level and a decrease in heart rate. So, the correct choice is D, which says that the heart rate falls below baseline level while the blood pressure decreases.

Question 10

___________________ is the most common non-stress-related cause of unconsciousness.&#10;A)An allergic reaction&#10;B)Postural hypotension&#10;C)An hyperglycemic reaction&#10;D)Epilepsy

Accepted Answer

Postural hypotension is a sudden drop in blood pressure upon standing up, which can lead to temporary unconsciousness. It is a common cause of fainting episodes in otherwise healthy individuals. Allergies, hyperglycemia, and epilepsy can also cause unconsciousness, but they are typically stress-related triggers.

Question 11

Which of the following is the single most important factor in management of the unconscious victim?&#10;A)summon EMS stat&#10;B)administration of aromatic ammonia&#10;C)administration of positive-pressure oxygen&#10;D)determination of the cause for loss of consciousness&#10;E)administration of BLS,as indicated

Accepted Answer

The answer of Which of the following is the single...

Question 12

Tingling and numbness of the extremities are most closely associated with:&#10;A)hypoglycemic reactions&#10;B)hyperventilation&#10;C)myocardial infarction&#10;D)Hypoglycemic reactions

Accepted Answer

The answer of Tingling and numbness of the extremities are...
