Question 1

H1). Which patient has least likely suffered a disruption of the reticular activating​ system? A. A patient complains of​ acute-onset slurred speech. B. A patient complains of frequent absence seizures. C. An unresponsive patient appears to have overdosed on prescribed painkillers. D. A patient has sustained minor lacerations from falling off a bicycle.

Accepted Answer

D. A patient has sustained minor lacerations from falling off a bicycle. Normal consciousness is regulated by a series of neurologic circuits in the brain that compose the reticular activating system. The RAS is essentially responsible for the functions of staying​ awake, paying​ attention, and sleeping. The patient least likely to be suffering a disruption to normal consciousness based on the mechanism of injury is the patient who sustained minor lacerations from a fall off a bicycle. The other patients are presenting with conditions that indicate disruption of normal consciousness.

Question 2

H2) Which case of altered mental status is least likely to be rapidly correctable by treating the underlying​ cause? A. An infant showing no sign of infection or trauma appears to be convulsing and unresponsive. B. A dehydrated patient is confused. C. An overdosing patient is unresponsive. D. A patient suffering an asthma attack is hypoxic and is losing consciousness.

Accepted Answer

A. An infant showing no sign of infection or trauma appears to be convulsing and unresponsive. The infant showing no sign of infection or trauma but who is convulsing and unresponsive is least likely to have a rapidly correctable case of altered mental​ status, because the underlying cause is unclear. The other patients have clear causes for their altered mental​ status: dehydration,​ hypoxia, or an overdose.

Question 3

``` H3). Which of the following is least necessary for a patient to maintain​ consciousness? A. Oxygen B. Medication C. Glucose D. Water ```

Accepted Answer

B. Medication Oxygen, glucose, and water are basic requirements for the body to maintain consciousness. A patient may take medication to manage or treat conditions that could lead to a loss of​ consciousness, but medication in this case is still not as basic a requirement as​ oxygen, glucose, or water.

Question 4

H4). Which of the following is the best explanation of how dehydration leads to altered brain​ function? A. Water is essential to keep the brain fully expanded. B. Water is necessary to remove waste products from the brain. C. Water is necessary to keep brain tissue hydrated. D. Water is necessary for electrical signals to travel throughout the brain.

Accepted Answer

C. Water is necessary to keep brain tissue hydrated. ​Oxygen, glucose, and water are essential for proper brain function. Water is necessary to keep the brain tissue properly hydrated.

Question 5

H5). Which of the following statements about altered mental status in pediatric patients is​ correct? A. Parents are usually poor historians regarding their children. B. Altered mentation in pediatric patients will be obvious. C. Parents are usually the best judges of their​ children's mental status. D. Assess mentation in children just as you would for an adult.

Accepted Answer

C. Parents are usually the best judges of their​ children's mental status. Children often cannot answer questions as adults​ can, and altered mental status can sometimes be difficult to assess in children. Parents are usually the best judges of their​ children's mentation.

Question 6

H6). In managing a patient who you have decided has an AVPU of​ "U," it will be important​ to: A. apply a pressure bandage. B. administer oxygen by nasal cannula. C. assess the​ patient's position and place an airway adjunct if necessary. D. use the Cincinnati Prehospital Stroke Scale.

Accepted Answer

C. assess the​ patient's position and place an airway adjunct if necessary. As you assess the airway and breathing of a patient with altered mental​ status, you should carefully watch for any indication of inadequate breathing. Remember that as mental status​ decreases, so may the​ patient's ability to control and keep the airway open. Position may be very important in keeping an airway open in a semiconscious patient. Be alert to the possible need for​ suction, and use airway adjuncts if necessary.

Question 7

``` H7). Hyperglycemia is​ high: A. blood sugar. B. carbohydrates. C. carbon dioxide. D. oxygen. ```

Accepted Answer

A. blood sugar.

Question 8

``` H8) Diabetes mellitus is also known​ as: A. sugar diabetes. B. hypoglycemia. C. stroke. D. hyperglycemia. ```

Accepted Answer

A. sugar diabetes. Diabetes mellitus is also called​ "sugar diabetes" or just​ "diabetes." It is the condition brought about by decreased insulin production or the inability of the body cells to use insulin properly. The person with this condition is a diabetic.

Question 9

``` H9). Which of the following findings are commonly associated with diabetic ketoacidosis​ (DKA)? A. Slow breathing B. Rapid breathing C. Low blood sugar D. Overhydration ```

Accepted Answer

B. Rapid breathing DKA is caused by high blood glucose levels. It results in profound dehydration and shock. The associated acidosis also leads to the accumulation of​ ketones, which in turn leads to rapid​ breathing, which is intended to​ "blow off" carbon dioxide.

Question 10

``` H10). In diabetic​ ketoacidosis, shock is usually caused​ by: A. vasodilation. B. dehydration. C. blood loss. D. vasoconstriction. ```

Accepted Answer

B. dehydration. DKA results in severe dehydration as the body attempts to compensate for high levels of blood glucose. Although these patients are profoundly​ hypovolemic, they have not lost any blood. Vasodilation or vasoconstriction are not common factors associated with DKA.

Question 11

H11). Diabetic problems are a common cause of altered mental status. Which of the following statements is true of diabetes​ mellitus? A. Type I diabetes is usually acquired in​ adulthood, and is often controlled by diet and oral medication. B. Insulin is a hormone secreted by the liver that is needed to move glucose from the blood into the cells. C. ​Hypoglycemia, or low blood​ sugar, may result from too much​ insulin, which causes glucose to be used up by the cells too rapidly. D. All patients with type II diabetes require insulin to maintain an appropriate blood sugar level.

Accepted Answer

C. ​Hypoglycemia, or low blood​ sugar, may result from too much​ insulin, which causes glucose to be used up by the cells too rapidly. If the patient has taken too much​ insulin, it will cause the glucose in the bloodstream to enter the​ cells, thereby dropping the BGL to a dangerous level. Type II diabetes typically occurs in​ adulthood, and is most commonly managed with diet and oral medication. Not all type II diabetics will require insulin. Insulin is secreted by the​ pancreas, not the liver.

Question 12

``` H12) What is the underlying pathophysiology of​ DKA? A. Not enough glucagon B. Not enough glycogen C. Too much insulin D. Not enough insulin ```

Accepted Answer

D. Not enough insulin The underlying pathology of DKA is that either the​ body's pancreas is not making enough insulin or the insulin that is being created is not working effectively. The result is a clinical condition of elevated blood glucose.

Question 13

H13) Which of the following statements about blood glucose meters is​ true? A. Blood glucose meters are not commonly used. B. Blood glucose meters are typically unreliable unless administered by specialized personnel in a hospital setting. C. Blood glucose meters are portable and reliable. D. People with diabetes typically use blood glucose meters no more than once a day.

Accepted Answer

C. Blood glucose meters are portable and reliable. One of the many advances in managing diabetes has been the development of​ portable, reliable blood glucose meters. People with diabetes now routinely test the level of glucose in their blood at least once a​ day, and sometimes as often as five or six times a day.

Question 14

``` H14) Which of the following readings on a glucometer for a symptomatic diabetic person with diaphoresis or mildly altered mental status would be of concern to the​ EMT? A. 118​ mg/dl B. 108​ mg/dl C. 78​ mg/dl D. 58​ mg/dl ```

Accepted Answer

D. 58​ mg/dl A value less than 60​ mg/dL (milligrams per​ deciliter) in a symptomatic diabetic​ (i.e., a patient with a mild alteration in mental status or who is diaphoretic​ [sweaty]) is typical of​ hypoglycemia, and indicates the need for prompt administration of glucose.

Question 15

H15) A​ 62-year-old female was found confused and diaphoretic. Her blood glucose level was assessed to be 35​ mg/dl. After administering a tube of oral​ glucose, you should​ next: A. perform a reassessment. B. make sure the patient can swallow. C. initiate transport. D. administer a second tube of oral glucose.

Accepted Answer

A. perform a reassessment. After giving oral glucose​ (or any​ medicine, for that​ matter), the EMT should start a reassessment phase to determine the​ patient's condition and whether any changes have occurred following administration of the medication. The ability to swallow must be assessed before administering oral​ glucose, not afterward. Transport is​ reasonable, but the patient should be reassessed​ first, as many patients who recover their mental status will not wish to be transported. A second tube should not be administered before reassessing.

Question 16

``` H16) If a patient becomes unresponsive during administration of oral​ glucose, the EMT​ should: A. insert a tongue depressor. B. give oxygen via a nonrebreather mask. C. reassess the airway and breathing. D. repeat the oral glucose. ```

Accepted Answer

C. reassess the airway and breathing. Because there is a risk that an unresponsive patient may aspirate the thick​ gel, if the patient becomes unresponsive during or after​ administration, the EMT should closely watch the airway to ensure patency.

Question 17

H17) A hypoglycemic​ 15-year-old female has been found unconscious. You should not administer oral​ glucose, because: A. the patient needs to consent to glucose administration. B. the patient is not awake enough to swallow. C. the patient is severely hypoglycemic. D. the​ patient's problem is too little insulin.

Accepted Answer

B. the patient is not awake enough to swallow. The most important decision point in choosing to give oral glucose is the​ patient's ability to swallow. Although a severely hypoglycemic patient may desperately need​ sugar, if she is unable to protect her​ airway, the administration of oral gel may be the worst thing you can do. We only administer oral glucose to those patients we feel can swallow it and protect their airway from aspiration.

Question 18

``` H18) You have a patient with an altered mental status that has developed over the past 23 ​days, according to family members. He is wearing a medical alert tag that is inscribed with the letters​ "DM." What is your initial field​ impression? A. Hyperinsulin episode B. Hyperglycemic episode C. Hypertension episode D. Hyperosmolar episode ```

Accepted Answer

B. Hyperglycemic episode The medical identification tag indicates that this patient is diabetic. A diabetic patient with a slow onset of mental status changes is more likely hyperglycemic then​ hypoglycemic, owing to the pathology of the disease process and the accumulation of acids that occurs in the hyperglycemic patient.

Question 19

H19) Which of the following statements is​ true? A. A complex partial seizure is often preceded by an​ aura, which might be a rising sensation in the stomach. B. A patient tends to experience an aura during the tonic phase of a convulsive seizure. C. Auras involving bright lights always precede all​ seizures, whether partial or generalized. D. A patient tends to experience an aura during the clonic phase of a convulsive seizure.

Accepted Answer

A. A complex partial seizure is often preceded by an​ aura, which might be a rising sensation in the stomach. A complex partial seizure is often preceded by an​ aura, which might be a rising sensation in the stomach. Auras do not always precede​ seizures, and they do not always involve a sensation of bright​ lights, although they might. Auras happen prior to​ seizures, not during them.

Question 20

``` H20) The phase of the seizure in which muscles become contracted and tense is called​ the: A. tonic phase. B. postictal phase. C. clonic phase. D. preictal phase. ```

Accepted Answer

A. tonic phase. The tonic phase is characterized by muscle rigidity. The​ patient's muscles become contracted and​ tense, and the patient exhibits extreme muscular rigidity with arching of the back. The clonic phase usually involves convulsions. The postictal phase is a period of depressed altered mental status following the clonic phase.

Question 21

H21) You witness an adult patient experiencing a seizure in which a progressive twitching of his right arm leads to his entire​ body's twitching. What can you reasonably say about the​ seizure's origin? A. The beginning of the seizure in the arm has no clinical relevance. B. The seizure was caused by a stroke on the right side of the brain. C. The seizure focus likely began in the right hemisphere of his brain. D. It was a partial seizure that became generalized to the entire body.

Accepted Answer

D. It was a partial seizure that became generalized to the entire body. The localized twitching indicates that the seizure began in only one hemisphere.​ Therefore, you may reasonably conclude that this was a partial seizure that became generalized to the entire body. Remember that the effects of one hemisphere are usually seen on the opposite side of the​ body, so a problem in the right hemisphere would most commonly be seen on the left side.

Question 22

``` H22) A​ 12-year-old boy experienced a tonic-clonic seizure after being struck in the head with a baseball. Which of the following would most likely be the cause of the​ seizure? A. Hypoxia B. Epilepsy C. Traumatic brain injury D. Toxins ```

Accepted Answer

C. Traumatic brain injury Given the most recent trauma to the​ head, you should first suspect traumatic brain injury. Although each of the other issues can cause​ seizures, here the mechanism of injury specifically points to traumatic brain injury.

Question 23

H23) If your patient is actively​ seizing, it may be necessary​ to: A. insert a bite block. B. place the patient on the floor or ground. C. forcibly restrain the patient. D. insert a tongue depressor.

Accepted Answer

B. place the patient on the floor or ground. Place the actively seizing patient on the floor or​ ground, but do not try to forcibly restrain the patient. You may position the patient on the side for drainage from the mouth if there is no possibility of spine injury. You should not insert any object into a seizing​ patient's mouth.

Question 24

H24) Which of the following statements about a seizure that is unusually long in duration is​ correct? A. Prolonged seizures mean that the patient has a history of seizures. B. Patients with prolonged seizures have a history of​ epilepsy, and often require no medical care. C. Patients with prolonged seizures should be suspected of being off their anti-seizure medication. D. Prolonged seizures can be​ life-threatening.

Accepted Answer

D. Prolonged seizures can be​ life-threatening. It is important for the EMT to recognize that seizures that are​ prolonged, or are associated with​ life-threatening conditions or injuries such as head injury or​ stroke, are abnormal and dangerous. Your prompt intervention in the prolonged or abnormal seizure may be lifesaving.

Question 25

H25) A​ 52-year-old male complains of not feeling well. Family members state that upon awakening this​ morning, they noticed that the patient had​ right-sided facial droop and was slurring his words slightly. The patient states that he is a​ diabetic, and 5 minutes​ ago, his blood glucose was 88​ mg/dL. After completing the primary​ assessment, you should​ next: A. administer oral glucose. B. recheck the​ patient's blood glucose. C. complete a Cincinnati Prehospital stroke assessment. D. administer​ high-concentration oxygen.

Accepted Answer

C. complete a Cincinnati Prehospital stroke assessment. Although the patient is a​ diabetic, his blood glucose level was within normal limits. You should next complete a Cincinnati Prehospital Stroke assessment. Oxygen is not necessary unless the patient is found to be hypoxic.

Question 26

``` H26) A stroke refers to the death or injury​ of: A. brain tissue. B. a major artery. C. heart muscle. D. a patient. ```

Accepted Answer

A. brain tissue. A stroke refers to the death or injury of brain tissue that is deprived of oxygen. This can be caused by blockage of an artery that supplies blood to part of the​ brain, or by bleeding from a ruptured blood vessel in the brain.

Question 27

``` H27) Which of the following conditions is most likely to lead to a​ stroke? A. Anemia B. Low blood pressure C. Asthma D. Longstanding high blood pressure ```

Accepted Answer

D. Longstanding high blood pressure Longstanding high blood pressure is a common cause of hemorrhagic stroke.

Question 28

H28) What mechanism is responsible for most​ strokes? A. An artery occluded by a clot or embolism B. Prolonged hypertension C. Low blood sugar D. High blood sugar

Accepted Answer

A. An artery occluded by a clot or embolism A stroke caused by a​ blockage, called an ischemic​ stroke, can occur when a clot or embolism occludes an artery. This mechanism is responsible for most strokes.

Question 29

H29) For a stroke​ patient, what is the most important treatment​ priority? A. Rapid transport to an appropriate destination B. Keeping the patient calm C. Administering supplemental​ oxygen, if necessary D. Monitoring the​ patient's airway

Accepted Answer

A. Rapid transport to an appropriate destination Stroke is a​ time-sensitive disorder. That​ is, the longer a vessel is​ blocked, the more damage occurs. You should keep this in mind when thinking about your overall treatment plan. Although there may be life threats that need immediate​ attention, and all of these interventions are​ important, commonly the most important treatment priority will be rapid transport to an appropriate destination.

Question 30

H30). Why is it necessary to take the patient to the hospital if the symptoms of a stroke have subsided by the time you arrive on the​ scene? A. The patient is likely to start seizing. B. The patient will need a period of bed rest. C. The patient still needs assessment and treatment for stroke. D. The patient will probably need to be given insulin.

Accepted Answer

C. The patient still needs assessment and treatment for stroke. If you suspect the patient has had a​ stroke, it is important to transport the patient promptly and notify the hospital of symptoms you see and the results of the Cincinnati Prehospital Stroke Scale. If you have a choice of​ hospitals, your protocols may direct you to a hospital capable of providing the most recent stroke treatments.

Question 31

H31) While assessing a patient using the Cincinnati Prehospital Stroke​ Scale, you note that the patient has​ acute-onset facial droop on the left side. This​ indicates: A. a normal finding for older patients. B. that the patient had a previous stroke. C. a likelihood that the patient is experiencing a stroke. D. the likelihood that the patient experienced a seizure.

Accepted Answer

C. a likelihood that the patient is experiencing a stroke. An abnormal finding in the Cincinnati Prehospital Stroke Scale indicates a strong likelihood of a stroke. The acute onset means that the facial droop is not from a previous stroke.

Question 32

``` H32) In assessing a possible stroke patient for arm​ drift, it is important to have the​ patient: A. keep both eyes open. B. close both eyes. C. blink rapidly. D. keep one eye open. ```

Accepted Answer

B. close both eyes.

Question 33

H33). For an unconscious stroke​ patient, you would provide oxygen based on saturation readings and transport the patient as soon as possible. What else should you​ do? A. Administer fluids by mouth in order to keep the patient hydrated B. Refrain from aggressive​ treatment, to avoid overtreatment C. Maintain an open airway D. Administer a​ clot-busting thrombolytic drug

Accepted Answer

C. Maintain an open airway You need to maintain the airway of an unconscious stroke patient in addition to providing oxygen as necessary and transporting the patient. Overtreatment of a suspected stroke patient is always better than ignoring an actual stroke. You would not administer a thrombolytic or administer fluids by mouth to an unconscious patient.

Question 34

``` H34). Syncope due to gastrointestinal bleeding is especially common​ in: A. diabetic patients. B. younger patients. C. older patients. D. otherwise healthy patients ```

Accepted Answer

C. older patients.

Question 35

``` H35) A​ 70-year-old male was sitting comfortably when he suddenly had a brief syncopal episode. His vital signs are P​ 46, R​ 20, BP​ 96/60, indicating a slow heart rate but normal respiration and a blood pressure that is not elevated. Which of the following do you suspect caused the syncopal​ episode? A. Hypovolemia B. DKA C. Cardiac dysrhythmia D. Hypertension ```

Accepted Answer

C. Cardiac dysrhythmia The patient has a slow heart rate on your arrival. This bradycardia is a likely cause of syncope. His blood pressure is not hypertensive. He may be​ hypovolemic, but the dysrhythmia is more likely. No signs of DKA are present.

Question 36

``` H36). A​ 24-year-old female who has been ill with diarrhea reports increasing dizziness that is made worse by standing up. She has a rapid pulse rate and is diaphoretic. She has no history of diabetes and takes no medications. What is the most likely source of her​ dizziness? A. Use of recreational drugs B. Low blood sugar C. Hypovolemia D. Stroke ```

Accepted Answer

C. Hypovolemia While there are a few​ possibilities, hypovolemia is the most likely cause. Although hypoglycemia is​ possible, her lack of diabetes makes this less likely. Drugs are a possible cause but are also less likely. A stroke is​ possible, but there are no other neurological findings.

Question 37

A​ 73-year-old female complains of a new onset of​ vertigo, and states that she almost passed out when she tried to stand. She is alert but weak. Her vital signs are P​ 70, R​ 20, BP​ 100/60. Her pulse oximeter reads​ 95%. The action among the following that it is least necessary to take for this patient is​ to: A. administer oxygen. B. assess the​ patient's likelihood to remain stable. C. lay the patient flat. D. loosen any tight clothing around the neck.

Accepted Answer

A. administer oxygen. The goal for a patient is at least a​ 94% oxygen saturation level with no signs of respiratory​ distress, so administering oxygen to this patient is not necessary. The other actions would be necessary to perform.

Question 38

H38). For a patient complaining of​ dizziness, what would you ask regarding​ vomiting? A. ​"Was the vomiting accompanied by an urge to​ urinate?" B. ​"Is the vomit clear or​ opaque?" C. ​"Is there blood or material resembling coffee​ grounds?" D. ​"Is the vomit black and​ tarry?"

Accepted Answer

C. ​"Is there blood or material resembling coffee​ grounds?"

Question 39

``` PT1) A patient was running a riding lawnmower in a closed garage and experienced dizziness. Immediately after opening the garage​ door, the patient experienced syncope that lasted for several moments. It is most likely that the cause of the​ patient's syncope​ was: A. toxicological. B. metabolic. C. structural. D. hypovolemic. ```

Accepted Answer

A. toxicological.

Question 40

PT2) A​ 26-year-old female complains of 6 hours of vomiting and diarrhea. She is dizzy and lightheaded but feels better while lying down. What​ follow-up question would be best to ask if the patient answers yes to the question​ "Have you had any similar episodes in the​ past?" A. ​"Do you have panic attacks or​ anxiety?" B. ​"Do you have a history of substance​ abuse?" C. ​"What cause was​ found?" D. ​"Are you​ diabetic?"

Accepted Answer

C. ​"What cause was​ found?"

Question 41

PT3) Which of the following statements is true of paralysis caused by​ stroke? A. ​Typically, paralysis from strokes affects only one side of the body. B. It is difficult to distinguish stroke from spinal​ injury, as both can cause paralysis to both legs. C. It is a good sign when patients experience only weakness in the​ extremities, as they will not deteriorate further. D. It is common for both sides of the body to be paralyzed from stroke.

Accepted Answer

A. ​Typically, paralysis from strokes affects only one side of the body.

Question 42

``` PT4) Aphasia is often seen​ in: A. hyperglycemic patients. B. hypoglycemic patients. C. syncope patients. D. stroke patients. ```

Accepted Answer

D. stroke patients.

Question 43

``` PT5) During your physical examination of a diabetic​ patient, you discover a small device on the​ patient's belt. There is a catheter from the device into the​ patient's abdomen. This device is​ likely: A. an implanted glucometer. B. a pacemaker. C. a feeding tube. D. an insulin pump. ```

Accepted Answer

D. an insulin pump.

Question 44

``` PT6). A​ 62-year-old male complains of weakness on one side of his body and slurred speech. After you arrive and evaluate the​ patient, you notice that the symptoms are beginning to subside. What is the likely cause of the​ patient's condition? A. Status epilepticus B. Transient ischemic attack C. Acute coronary syndrome D. Subdural hematoma ```

Accepted Answer

.B. Transient ischemic attack

Question 45

``` PT7). A person in a hypoxic state experiences an altered mental status because in the reticular activating​ system, oxygen is needed​ to: A. perfuse the brain tissue. B. nourish the brain tissue. C. hydrate the brain tissue. D. protect the brain tissue. ```

Accepted Answer

A. perfuse the brain tissue

Question 46

``` PT8). A​ 66-year-old female displays two findings from the Cincinnati Prehospital Stroke Scale. What do these findings​ indicate? A. A​ 100% chance of an acute stroke B. A previous stroke C. Very little chance of an acute stroke D. A​ 70% chance of an acute stroke ```

Accepted Answer

D. A​ 70% chance of an acute stroke

Question 47

PT9). A​ 45-year-old male presents agitated and confused. Your assessment identifies an oxygen saturation of​ 90%. You should​ next: A. administer oxygen. B. restrain the patient for safety. C. conduct a Cincinnati Prehospital stroke examination. D. administer oral glucose.

Accepted Answer

A. administer oxygen.

Question 48

``` PT10). Which of the following substances specifically nourishes the brain to enable​ consciousness? A. Water B. Glucose C. Oxygen D. Carbon dioxide ```

Accepted Answer

B. Glucose

Question 49

``` PT11) To optimize the care of a stroke patient who is a potential candidate for​ thrombolytics, an EMT can determine and document the exact time​ of: A. arrival on scene. B. taking the​ patient's vital signs. C. packaging the patient for transport. D. onset of symptoms ```

Accepted Answer

D. onset of symptoms.

Question 50

``` PT12) The postictal phase of a tonic-clonic seizure involves the​ patient's transitioning from full loss of consciousness​ to: A. full mental status. B. hypoxia. C. brain death. D. stroke. ```

Accepted Answer

A. full mental status. (Page 635) Postictal Phase - the period of time immediately following a tonic-clonic seizure in which the patient goes from full loss of consciousness to full mental status

Question 51

PT13). Which of the following is characterized by​ sudden, temporary loss of consciousness caused by insufficient blood flow to the​ brain, with return of consciousness almost immediately on becoming​ supine? A. Concussion B. Transient ischemic attack​ (TIA) C. Vasovagal syncope D. Reversible ischemic neurological disorder​ (RIND)
