• A:both oxygen and glucose are needed for brain function.
• B:the majority of stroke patients have a history of diabetes.
• C:the most common cause of a stroke is hypoglycemia.
• D:they are both caused by low levels of glucose in the blood.: • A:both oxygen
and glucose are needed for brain function.
Reason: Although stroke and hypoglycemia are two distinctly different conditions,
their signs and symptoms are often similar. This is because the brain requires both
oxygen and glucose to function normally. An acute ischemic stroke is caused by
a lack of oxygen to a part of the brain due to a blocked cerebral artery, whereas
hypoglycemia (low blood glucose level) deprives the entire brain of glucose. In either
case, the patient presents with signs of impaired brain function (ie, slurred speech,
weakness, altered mental status). Both conditions may lead to permanent brain
damage or death if not treated promptly.
2. When dealing with an emotionally disturbed patient, you should be MOST
concerned with:
• A:gathering all of the patient's medications.
• B:safely transporting to the hospital.
• C:whether the patient could harm you.
• D:obtaining a complete medical history.: You selected C; This is correct!
,Reason: When managing any patient with an emotional or psychiatric crisis, your
primary concern is your own safety. Safely transporting the patient to the hospital is
your ultimate goal. If possible, you should attempt to obtain a medical history and
should take any of the patient's prescribed medications to the hospital. However,
this should not supercede your own safety or interfere with safely transporting the
patient.
3. You are at the scene where a man panicked while swimming in a small lake.
Your initial attempt to rescue him should include:
• A:rowing a small raft to the victim.
• B:reaching for the victim with a long stick.
• C:throwing a rope to the victim.
• D:swimming to the victim to rescue him.: You selected B; This is correct!
Reason: General rules to follow when attempting to rescue a patient from the water
include "reach, throw, row, and then go." In this case, you should attempt to reach the
victim by having him grab hold of a large stick or similar object. If this is unsuccessful,
, throw the victim a rope or flotation device (if available). If these are not available, row
to the patient in a small raft (if available). Going into the water to retrieve the victim
is a last resort. The rescuer must be a strong swimmer because patients who are in
danger of drowning are in a state of blind panic and will make every attempt to keep
themselves afloat, even if it means forcing the rescuer underwater.
4. How should you classify a patient's nature of illness if he or she has a low
blood glucose level, bizarre behavior, and shallow breathing?
• A:Behavioral emergency
• B:Altered mental status
• C:Respiratory emergency
• D:Cardiac compromise: The correct answer is B;
Reason: The nature of illness (NOI) is the medical equivalent to mechanism of
injury (MOI). Altered mental status should be the suspected NOI in any patient with
any fluctuation in level of consciousness, which can range from bizarre behavior to
complete unresponsiveness. Causes of an altered mental status include hypo- or
hyperglycemia, head trauma, stroke, behavioral crises, drug overdose, and shock,
among others.
5. A young female is unresponsive after overdosing on an unknown type of
drug. Her respirations are slow and shallow and her pulse is slow and weak.
Which of the following drugs is the LEAST likely cause of her condition?
• A:Seconal
• B:Heroin
