EMT Practice Exam Medical and OBGYN Flashcards
While assessing a medical patient, what mnemonic will assist the EMT with finding out details of the chief complaint?
a. AVPU
b. OPQRST
c. SAMPLE
d. DCAP-BTLS
B. Rationale: The “OPQRT” mnemonic will assist the EMT with exploring the chief complaint. It consists of onset, provocation/palliation, quality, radiation, severity, and time. AVPU deals with ascertaining the mental status, SAMPLE deals more globally with the patient’s background (i.e., meds, history, allergies), and DCAP-BTLS is used when assessing for traumatic injuries or conditions.
Which of the following is NOT considered to be one of the components of the secondary exam in a responsive patient with a medical emergency?
a. Baseline vital signs
b. Focused physical exam
c. History of the present illness
d. Determination of patient priority
D. Rationale: The determination of patient priority is actually more of a clinical outcome of completing the assessment of a patient and determining that the patient’s status is critical. Most commonly it is determined at the end of the primary survey, although it could be determined at any point in time. The other parameters mentioned—vitals, physical exam, and history—are all normal parts of the secondary assessment. The fourth component of the secondary exam is the history of the present illness.
Upon initial questioning, a patient complains of multiple things: chest pain, dyspnea, and abdominal pain. What should be the next course of action for the EMT?
a. Ask the patient which thing bothered him first
b. Ask the patient which thing is bothering him the most
c. Treat the patient as if he has three chief complaints
d. Assume that the chest pain is the chief complaint due to its potential severity
B. Rationale: Asking the patient for clarity of the chief complaint (i.e., which thing is bothering him the most) will allow the EMT to focus care interventions on the thing that is troubling the patient the greatest. Although what was bothering him first is important, it will not necessarily direct patient care. Treating the patient for three chief complaints may lead to multiple interventions that may contradict each other, and assuming the chief complaint is chest pain will not be true in all instances.
Which of the following medical patients will the EMT perform a rapid physical exam on?
a. An eighty-six-year-old unresponsive diabetic patient
b. A nine-year-old boy with asthma who is scared
c. A thirty-two-year-old male with respiratory distress
d. A sixty-year-old psych patient threatening to kill himself
A. Rationale: The rapid physical exam is performed on medical patients when they have an altered mental status and cannot provide reliable answers to the EMT’s questions. The focus of the exam is to find life-threatening conditions or evidence that can help the EMT determine what is wrong with the patient. The other patients listed were conscious and hence would probably not receive the rapid physical exam; rather, they would receive a focused physical exam.
A patient with an injury or dysfunction to what region of the brain may have problems staying awake or paying attention?
a. Cerebellum
b. Hypothalamus
c. Foramen magnum
d. Reticular activating system
D. Rationale: The reticular activating system is a region of nerve fibers deep in the brain that controls consciousness by way of staying awake, paying attention, and indicating when sleeping should occur. Thus, an injury or dysfunction here can easily cause the patient to be unresponsive. The hypothalamus is part of the endocrine system, and the cerebellum is basically the involuntary control of voluntary muscles. The foramen magnum is actually a part of the skull.
The patient with diabetes has a pathophysiologic problem with what hormone?
a. Insulin
b. Glucose
c. Dopamine
d. Norepinephrine
A. Rationale: A diabetic patient’s fundamental problem is that insulin is either not being produced or not working as efficiently as it was intended to (type 1 and type 2 diabetes, respectively). Glucose is not a hormone; actually, it is the dietary fuel used to create energy. Dopamine and norepinephrine are both hormones, but they operate within the sympathetic nervous system.
A diabetic patient takes her insulin medication regularly and watches what she eats. However, one day she is not feeling well, and she vomits a few times after breakfast. What medical emergency related to diabetes could this cause?
a. Hypertension
b. Hypotension
c. Hypoglycemia
d. Hyperglycemia
C. Rationale: The diabetic’s regulation of sugar can become problematic if she is not stringently watching her diet and medication use. In this situation where the medications are taken to lower the sugar but the patient vomits the food up, there will be an inadequate amount of sugar in the blood for the insulin and the sugar will drop drastically and dangerously low (hypoglycemia). Hyperglycemia usually happens when the insulin levels are too low, and changes in blood pressure are really not part of the diabetic process.
Within the body of the diabetic patient, what organ is most sensitive to lowered levels of glucose?
a. Liver
b. Brain
c. Heart
d. Pancreas
B. Rationale: Almost all tissues of the body can store a certain amount of glucose that can help temporarily buffers drop in glucose levels. The only organ that cannot do tis is the brain. As such, if sugar drops too low, the neurons of the brain start to malfunction, which essentially causes changes in the mental status. Hence, the brain is the most sensitive organ to decreasing glucose levels.
A diabetic patient may be considered hypoglycemic if he has an altered mental status and a blood sugar level less than what value?
a. 80 mg/dL
b. 100 mg/dL
c. 120 mg/dL
d. 140 mg/dL
A. Rationale: When a diabetic patient starts to become hypoglycemic, there is usually a change in mental status, he becomes sweaty, and his heart rate increases. The blood sugar can complete this clinical picture as a value less than 80 mg/dL is considered to be hypoglycemic in the symptomatic patient. Naturally, levels lower than this further demonstrate hypoglycemia, but 80 mg/dL is when the suspicion becomes confirmed. Levels higher than 80 (up to 120 mg/dL) are consistent with normal glucose levels.
You are caring for a diabetic patient with low blood sugar. The patient is unresponsive with sonorous airway sounds. He has a rapid pulse, and peripheral perfusion is intact. Which of the following interventions is of utmost concern for this patient?
a. Manual airway technique
b. Suctioning out the airway
c. Providing high-flow oxygen
d. Administration of oral glucose
A. Rationale: A hypoglycemic patient is in dire need of glucose to return normal brain activity. However, in this patient the glucose level has dropped so low that the patient is now unable to maintain his own airway. As such, the airway now becomes the immediate concern, and a manual technique is needed to open the airway. The use of oxygen is important, but that will come after the airway is open. The use of oral glucose is not warranted ow due to the patient’s inability to keep his airway open. There is no need to suction the airway as there is no evidence of obstruction.
A patient with what type of seizure is most likely to present as unresponsive?
a. Partial
b. Generalized
c. Focal motor
d. Jacksonian seizures
B. Rationale: There are two types of seizures: partial seizures and generalized seizures. Partial seizures (also known as focal-motor seizures) occur when the seizure activity is occurring to one side of the brain and, hence, one side of the body. Generalized seizures affect both sides of the brain and cause the patient to be unresponsive. Jacksonian seizures are a type of partial seizure in which muscle tremors are progressive (i.e., fingers then hand then arm and so on).
You are caring for a patient who is experiencing a generalized seizure. During the tonic-clonic phase, which of the following management strategies should you employ?
a. Apply high-flow oxygen via nonrebreather mask, and position the supine
b. Loosen restrictive clothing and protect the patient from injury
c. Apply oral glucose and place the patient in the recovery position
d. Restrain the patient physically to avoid harm and transport immediately
B. Rationale: A patient experiencing a generalized seizure will need multiple interventions employed quickly. This includes placing the patient on her side for drainage of fluids (if no c-spine injury is noted), loosening of restrictive clothing, removing objects from around the patient that she may fall upon or that might injure her, and protecting the patient from bodily injury without physically restraining her. The best answer described is loosening the clothing and protecting the patient from harm.
You are assessing a patient who has confusion, has difficulty in speaking, and is unable to get out of bed due to left-sided weakness. The symptoms, the family states, occurred very suddenly. The blood pressure is 210/130, the pulse is 98, and respirations are 18. As an EMT, what should be your most likely field impression for the patient’s condition?
a. Stroke
b. Seizure
c. Hyperglycemia
d. Hypoperfusion
A. Rationale: A stroke occurs when a region of the brain is underperfused due to either an occluded blood vessel or a ruptured blood vessel. The brain tissue involved starts to malfunction, which causes changes in mental status and often weakness or paralysis on one-half of the body. Oftentimes, the blood pressure is high in these patients. Hyperglycemia does not have the unilateral findings and is usually a slow onset; in addition, hypoperfusion is unlikely given the blood pressure. Finally, seizures have a rapid onset, but their unilateral findings when present are muscular tremors or convulsions, not weakness.
A patient who has recurrent episodes of unilateral weakness, headaches, vision disturbances, or confusion that resolves on its own in a short period of time is likely experiencing what emergency?
a. MI
b. CVA
c. HTN
d. TIA
D. Rationale: A transient ischemic attack (TIA) is a medical emergency in which there is a temporary diminishment or cessation of blood flow to an area of the brain, causing neurological impairment and possible headaches—much like a stroke. The small clot blocking the blood flow breaks up and normal blood flow returns, as does the neurological deficit. Often a TIA is considered an indication of an impending stroke. HTN refers to hypertension, which does not cause unilateral signs. The same is true for a heart attack (MI). A CVA is a cerebral vascular accident, which is an older name for a stroke.
You are working with a new EMT on your squad. After a call for an MI patient who became unresponsive, the EMT asks you how a heart attack could cause such a thing. Which of the following most correctly answers this question?
a. “Increased blood flow due to tachycardia.”
b. “A drop in blood flow to the brain from a failing heart.”
c. “The heart was extracting too much oxygen from the bloodstream, leaving an insufficient amount for the brain to use.”
d. “The patient’s lungs were failing due to the drop in left ventricular contraction.”
B. Rationale: When a person is experiencing an MI, a portion of the heart is dying due to a lack of oxygen. That section will eventually stop contracting normally and will contribute to a drop in cardiac output to the brain and body. If this drop is too great, the patient’s mental status can deteriorate due to poor blood flow. Also, the heart does not extract so much oxygen that the other organs fail (it takes only what it needs), and the right ventricle (not left) pumps blood to the lungs.
