Questions & Verified Answers | Latest Update | Graded A+
1. During your assessment of a 70-year-old woman, she tells you that she takes
blood-thinning medication and has to wear compression stockings around
her legs. This information should make you suspect that she has:
Sickle-cell disease
Deep vein thrombosis
Hemophilia
Severe hyperglycemia
2. Which of the following is TRUE regarding glucose use by the cells?
Glycogen is stored in the pancreas for cellular use.
Brain cells require glucose to function.
The brain requires insulin to absorb glucose.
The brain can convert to using fats for energy.
3. Describe the physiological reason behind Kussmaul respirations in patients
with metabolic acidosis.
Kussmaul respirations are a sign of respiratory failure.
Kussmaul respirations occur as the body attempts to eliminate acids
from the blood through increased respiratory rate and depth.
Kussmaul respirations are a response to low oxygen levels in the
blood.
Kussmaul respirations indicate an attempt to increase blood glucose
levels.
,4. Which of the following statements best describes diabetic ketoacidosis?
It occurs due to lack of insulin, which prevents the body's cells from
absorbing and utilizing any glucose in the blood. As a result, the body
switches its metabolism to breakdown fat to produce energy. This
process produces alkylotic ketones as a byproduct and they build up
in the blood causing metabolic alkalosis.
It occurs due to lack of insulin, which prevents the body's cells from
absorbing and utilizing any glucose in the blood. As a result, the
body switches its metabolism to breakdown fat to produce energy.
This process produces acidic ketones as a byproduct and these
build up in the blood causing metabolic acidosis.
It occurs due to lack of insulin, which causes the body's cells to
absorb and utilize an abnormally high level of glucose. As a result, the
body switches its metabolism to breakdown fat to produce energy.
This process produces acidic ketones as a byproduct and these build
up in the blood causing metabolic acidosis.
It occurs due to overproduction of insulin, which prevents the body's
cells from absorbing and utilizing any glucose in the blood. As a
result, the body switches its metabolism to breakdown fat to produce
energy. This process produces acidic ketones as a byproduct and
these build up in the blood causing metabolic acidosis.
5. If a patient presents with warm, dry skin and acetone breath, what immediate
action should an EMT take?
Administer epinephrine immediately.
Assess blood glucose levels and provide appropriate treatment.
Give the patient oral glucose without checking levels.
Encourage the patient to drink water.
,6. What is the normal range for blood glucose levels in milligrams per deciliter
(mg/dL)?
130 and 150 mg/dL.
160 and 200 mg/dL.
80 and 120 mg/dL.
60 and 80 mg/dL.
7. What condition is indicated by excessive urination in a patient with type 1
diabetes?
Urinary tract infection
Insulin overdose
Low blood glucose level
Significantly hyperglycemic
8. What is the recommended method for removing a honeybee stinger from the
skin?
Scraped away from the skin
Irrigated with copious amounts of water
Left in place and covered
Squeezed with tweezers and removed
9. Describe why the lateral portion of the thigh is the preferred injection site for
epinephrine administration.
The lateral portion of the thigh is less painful than other injection sites.
The lateral portion of the thigh is easier to access in emergencies than
other sites.
, The lateral portion of the thigh is the only site approved for
epinephrine administration.
The lateral portion of the thigh has a large muscle mass that allows
for rapid absorption of epinephrine into the bloodstream.
10. What is the definition of an allergic reaction as per EMT protocols?
Release of erythrocytes in response to a foreign substance
A direct negative effect on the body by an external substance
An exaggerated immune system response to any substance
Destruction of the immune system, by an external substance
11. Which of these statements made by an Emergency Medical Technician
indicates a correct understanding of glucose in the human body?
"Once ingested, glucose is broken down into carbohydrates and used
for energy."
"The cells of the brain cannot store glucose, and are uniquely
sensitive to low glucose levels."
"Glucose is transformed into fats, which the cells of the body use for
energy."
"All cells in the body require glucose for energy and cannot use
anything else."
12. Which of the two has an increased thirst?
hypoglycemia
hyperglycemia
