EMT Medical Sample Test 1 — Questions and Answers

Question 1: You arrive on scene to find a patient with an altered mental status... You arrive on scene to find a patient with an altered mental status. You quickly scan the scene. Which of the following items will help to point you in the right direction in finding a cause of the altered mental status?

Unkempt house with animal fur and dirt on the floor
Medications including high blood pressure, anxiety and depression (Correct answer)
A smell of dirty clothes and cat feces
Over the counter (OCT) pain relievers

Correct answer: Medications including high blood pressure, anxiety and depression

Medications, especially those for chronic conditions like high blood pressure, anxiety, and depression, can significantly impact a patient's mental status if taken incorrectly, missed, or if there are adverse reactions. Knowing a patient's prescription medications provides crucial clues about underlying medical conditions and potential drug interactions or overdoses. The other options describe environmental factors or general OTC drugs, which are less directly indicative of a specific medical cause for altered mental status.

Question 2: Your patient is not responding to your loud verbal stimuli. You find the following medications: Glucophage and Lipitor. What is the likely cause of the patient’s problem?

High cholesterol
High blood pressure
Diabetic reaction (Correct answer)
Coronary Artery Disease

Correct answer: Diabetic reaction

Glucophage (metformin) is a medication specifically used to treat Type 2 diabetes by lowering blood sugar levels. A patient who is unresponsive and takes Glucophage is highly likely to be experiencing a diabetic emergency, such as hypoglycemia (low blood sugar) or hyperglycemia (high blood sugar). While Lipitor treats high cholesterol, Glucophage directly points to diabetes as the primary concern for altered mental status.

Question 3: Your neuro assessment of an unresponsive patient reveals pin point pupils. What is your primary field diagnosis?

Beta blocker overdose
Insulin overdose
Aspirin
Narcotic (Correct answer)

Correct answer: Narcotic

Pinpoint pupils (miosis) are a classic and highly indicative sign of opioid (narcotic) overdose. Opioids depress the central nervous system, leading to respiratory depression and constricted pupils. While other conditions can cause miosis, in an unresponsive patient, narcotic overdose is the most critical and common cause associated with pinpoint pupils that EMS providers must consider.

Question 4: Your patient is a known diabetic who ... Your patient is a known diabetic who takes up to four insulin injections a day. Today he is found unresponsive, diaphoretic, and tachycardic. He is also only breathing 18 times a minute. What is likely the patient’s chief medical issue?

Hypoglycemia (Correct answer)
Hyperglycemia
CVA
Hypertensive crisis

Correct answer: Hypoglycemia

The symptoms of unresponsiveness, diaphoresis (sweating), and tachycardia (rapid heart rate) in a known diabetic patient who takes insulin are classic signs of hypoglycemia (low blood sugar). Insulin lowers blood sugar, and taking too much or not eating enough can lead to a rapid drop in glucose, causing these symptoms as the body tries to compensate. Hyperglycemia typically presents with dry skin, thirst, and Kussmaul respirations, which are different from the patient's presentation.

Question 5: You find that your diabetic patient is hypoglycemic. You have oral glucose to give to the patient. You will give 15 grams of instant glucose to the patient except if they are ___________?

Conscious with blood sugar
Semi conscious with gag reflex and the ability to swallow
Semi conscious without the ability to swallow (Correct answer)
Conscious with an altered mental status and blood sugar of 80mg/dl

Correct answer: Semi conscious without the ability to swallow

Oral glucose should only be administered to patients who are conscious and have an intact gag reflex, ensuring they can safely swallow without aspirating. A patient who is semi-conscious and lacks the ability to swallow is at high risk for aspiration if oral glucose is given. In such cases, alternative routes like intravenous dextrose or intramuscular glucagon are necessary.

Question 6: Which of the following is an often fatal complication of diabetes and is also the first indication of diabetes in many young patients?

Hypoglycemia
Hypertension
Cardiovascular disease
Diabetic Ketoacidosis (DKA) (Correct answer)

Correct answer: Diabetic Ketoacidosis (DKA)

Diabetic Ketoacidosis (DKA) is a severe and potentially life-threatening complication of diabetes, particularly Type 1, where the body produces high levels of blood acids called ketones. It is often the initial presentation of Type 1 diabetes in children and young adults, as their bodies suddenly stop producing insulin. While other options are complications, DKA is uniquely characterized by its acute, severe onset and common role as a first indicator in young patients.

Question 7: Diabetic Ketoacidosis (DKA) has the following signs and symptoms... Diabetic Ketoacidosis (DKA) has the following signs and symptoms; Acetone on breath, dry skin, poor skin turgor, altered mental status, confusion, thirst, and frequent urination. What other symptoms are associated with DKA?

Normal mental status
Appearance of intoxication (Correct answer)
Tremors
Diaphoresis

Correct answer: Appearance of intoxication

Patients experiencing Diabetic Ketoacidosis (DKA) often present with an altered mental status, confusion, and a fruity (acetone) breath odor, which can make them appear as if they are intoxicated. This 'appearance of intoxication' is a common and dangerous misdiagnosis, highlighting the importance of checking blood glucose levels in such patients. Unlike hypoglycemia, DKA typically does not cause diaphoresis or tremors.

Question 8: There are two types of cerebral vascular accidents (i.e., strokes). The most common is an ischemic stroke. What is the other type?

Transient ischemic attack
Hemorrhagic (Correct answer)
Thrombotic
Embolic

Correct answer: Hemorrhagic

Strokes are broadly categorized into two main types: ischemic and hemorrhagic. An ischemic stroke, the most common type, occurs when a blood clot blocks blood flow to the brain. A hemorrhagic stroke, the other type, occurs when a blood vessel in the brain ruptures, causing bleeding into the brain tissue. Thrombotic and embolic strokes are sub-types of ischemic strokes, and a TIA is a temporary stroke-like event.

Question 9: For a condition to be diagnosed as a transient ischemic attack (TIA), the symptoms must be resolved in 24 hours ______________?

With some minor deficits
With some major long lasting effects
With out any memory effects
With out any permanent effects (Correct answer)

Correct answer: With out any permanent effects

A Transient Ischemic Attack (TIA) is defined as a temporary episode of neurological dysfunction caused by focal brain, spinal cord, or retinal ischemia, without acute infarction. Crucially, for a TIA diagnosis, all symptoms must resolve completely, leaving no permanent neurological deficits. If any symptoms persist or there is evidence of brain tissue damage, it is classified as an ischemic stroke, not a TIA.

Question 10: To assess a patient with a stroke, there are two major assessment tools... To assess a patient with a stroke, there are two major assessment tools: the Cincinnati Stroke Scale and the Los Angeles Prehospital Stroke Screen. Which one of these two tools uses arm drift as a diagnostic tool?

Neither
Cincinnati Stroke Scale (Correct answer)
Los Angeles Prehospital Stroke Screen
Both

Correct answer: Cincinnati Stroke Scale

The Cincinnati Stroke Scale is a widely used prehospital assessment tool that evaluates three key signs of stroke: facial droop, arm drift, and abnormal speech. Arm drift is specifically assessed by asking the patient to hold both arms out in front of them with palms up, and observing if one arm drifts downward. The Los Angeles Prehospital Stroke Screen uses different criteria, including age, history of seizures, and blood glucose, among others.

Question 11: Stroke symptoms often the same as other medical problems... Stroke symptoms often present the same as other medical problems. To prevent improper treatment for the signs and symptoms, working through the differentials is a must. Hypoglycemia is often mistaken for a CVA. How can a clinician rule in or out this differential?

Check pupils
Check blood sugar (Correct answer)
Check grips
Check arm drift

Correct answer: Check blood sugar

Hypoglycemia (low blood sugar) can mimic stroke symptoms, causing altered mental status, weakness, and speech difficulties. The most critical and definitive way to differentiate between a stroke and hypoglycemia is to check the patient's blood glucose level. A rapid bedside glucose test can quickly confirm or rule out hypoglycemia as the cause of the patient's symptoms, guiding appropriate treatment.

Question 12: The clinician's best role in the assessment and treatment of a stroke patient is rapid recognition and transport to a stroke center. What is the window of opportunity from the onset of symptoms until treatment?

any time before symptoms resolve
three hours (Correct answer)
in the first 24 hours
once you have a stroke there is no chance to fix it

Correct answer: three hours

For ischemic stroke patients, the most effective treatment, thrombolytic therapy (e.g., tPA), must be administered within a narrow time window from the onset of symptoms to be beneficial and safe. This critical window is typically considered to be within three to four and a half hours for eligible patients. Rapid recognition and transport are crucial to ensure patients can receive this time-sensitive treatment.

Question 13: Statements from patients are used as assessment tools. Which of the following statements about stroke symptoms should cause the clinician to use a higher index of suspicion?

This is the worst headache I have ever had. (Correct answer)
This headache is behind my right eye.
My head is throbbing.
Bright light causes my head to hurt worse.

Correct answer: This is the worst headache I have ever had.

A sudden, severe headache described as 'the worst headache of my life' is a classic and highly concerning symptom, often indicative of a subarachnoid hemorrhage (a type of hemorrhagic stroke). This specific description warrants an immediate and high index of suspicion for a serious intracranial event. Other headache descriptions are less specific to acute stroke and can be associated with various benign or less critical conditions.

Question 14: A medical condition where the patient sometimes suffers convulsions or seizure activity is known as?

Postictal state
Tonic-clonic
Focal motor
Epilepsy (Correct answer)

Correct answer: Epilepsy

Epilepsy is a chronic neurological disorder characterized by recurrent, unprovoked seizures, which are episodes of abnormal electrical activity in the brain. While 'tonic-clonic' and 'focal motor' describe specific types of seizures, and 'postictal state' refers to the period after a seizure, 'epilepsy' is the overarching medical condition defined by the predisposition to having seizures.

Question 15: When assessing a patient complaining of depression, which of the following would be most suggestive that the patient is at risk for suicide?

Previous attempt that was unsuccessful (Correct answer)
Packing away of cherished possessions
Hostility toward concerned family members
Recent diagnosis of hypertension

Correct answer: Previous attempt that was unsuccessful

A history of previous suicide attempts is the single strongest predictor of future suicide attempts and completed suicide. Each attempt increases the risk significantly. While other factors like giving away possessions can be warning signs, a past attempt indicates a higher level of intent and a proven capacity to act on suicidal thoughts.
