Neurological assessment & vital signs and medical emergencies Flashcards
What’s the definition of Physical Evaluation ? Sometimes referred to as?
an ongoing process of observation, assessment and measurement to note and evaluate any changes in the patient’s condition. Sometimes referred o as “eyeballing.”
What 4 criteria are assessed with physical evaluation?
- Skin colour
- Skin temperature
- Breathing
- Level of consciousness (LOC)
Skin colour:
What are you looking for, why does this change happen, where do you see it, and under what circumstances should you stay with the patient?
- Look for cyanosis (bluish color in the skin).
- Caused by lack of oxygen in the tissues.
- Easily seen on mucous membranes such as lips and lining of the mouth.
- If a patient looks pale and anxious and states they “do not feel well,” the technologist should NOT leave the patient.
Skin Temperature:
What does contact through touch allow? What characteristics does an acutely ill person in pain likely display?
- Contact through touch also allows ongoing physical observation.
- Acutely ill patient who is in pain is likely pale, cool and diaphoretic (i.e., cold sweat).
What could hot dry skin indicate? Moist skin?
Hot, dry skin may indicate a fever, while moist skin may only be a response to the environment.
Breathing:
What can changes signal?
What does normal breathing sound/look like?
What does abnormal beathing look/sound like?
What is usually the 1st sign of respiratory distress?
- Changes may signal onset of serious distress.
- Normal breathing is quiet and calm.
- Abnormal breathing is audible, wheezing, gasping or coughing.
- Sudden onset of rapid, shallow breathing is usually first sign of respiratory distress.
What are the 4 general Level of Consciousness?
- Alert and responsive
- Drowsy but responsive
- Unconscious but reactive to painful stimuli
- Comatose
What 2 things are key to remember when communicating with a patient who is drowsy or in a stupor?
- They can’t be relied upon to remember instructions.
- They are not responsible for their actions or answers.
Why is close monitoring of Intoxicated patients who may appear to have just “passed out” LOC still important?
because the alcohol may obscure important symptoms.
What should ALWAYS be kept in mind with communication with and around unconscious patients?
Make no statement in front of the unconscious patient you wouldn’t make if they were awake. Hearing can still function.
Glasgow coma scale: What are the 3 main criteria? What is the highest possible score?
- Eyes Open
- Verbal response
- Motor response
- Scored out of 15.
Glasgow coma scale:
What are the 4 Responses within the eyes open category (LOWEST to HIGHEST score)?
- None
- To pain
- To speech
- Spontaneously
Glasgow coma scale:
What are the 5 Responses within the Verbal Response category (LOWEST to HIGHEST score)?
- None
- Incomprehensible sounds
- Inappropriate words
- Confused
- Oriented
Glasgow coma scale:
What are the 6 Responses within the Motor Response category (LOWEST to HIGHEST score)?
- Flaccid
- Abnormal Extension
- Abnormal Flexion
- Flexion Withdrawal
- Localized pain
- Obeys commands
Who might exhibit similar symptoms to trauma patients under the influence of alcohol?
Patients taking pain medication, or insulin-dependent patients who have gone too long without insulin.
What can it mean when a patient is alert and oriented when admitted becomes increasingly incoherent, drowsy, and stuporous?
May be showing signs of increased intracranial pressure (insane clown posse)
What is the french term for a “backlash” injury and how does it occur?
Conrecoup, occurs when a severe blow to the head causes the brain to bounce side-to-side, resulting in injury on opposite side from the blow.
Mild to moderate amount of head damage characterized by “seeing stars”
Concussion
What can a rise in ICP cause?
Seizures, loss of consciousness, respiratory arrest
What are 3 earliest signs of ICP?
- Irritability
- Lethargy
- Pulse and respiration both slow

Describe the characteristics of an individual who may suffer from Type 2 diabetes
obese, over the age of 40 with marked family tendency.
List the signs and symptoms of hypoglycemia.
- sudden onset of weakness, sweating, tremors, hunger, cold/clammy skin/diaphoresis,*
- Headache, tachycardia, impaired vision, personality change, loss of consciousness*
Can a Type 1 diabetic be hyperglycemic or hypoglycemic?
yes
The patient’s breath has a “fruity odor” to it. Name the type of diabetic reaction occurring.
hyperglycemia
What treatment should a diabetes insipidus patient receive?
fluid replacement
What is the treatment for HHNK?
Fluid administration to rapidly expand intravascular volume
Give an example of when a patient may experience hypoglycemia in the D.I department?
Patients who have fasted for procedures or exams.
List the negative impact to the body a person with Type 1 diabetes may experience.
Circulatory impairment of vision, kidneys or extremities
What is DI?
Diabetes Insipidus (DI) – Excessive urination caused by inadequate amounts of antidiuretic hormone in the body or failure of kidney to respond to hormone.
What is DM?
Diabetes Mellitus (DM) – Disease marked by alternating episodes of hypoglycemia and hyperglycemia, which can be difficult to control. The varying amount of glucose can result from:
- Defects in insulin secretion (i.e., pancreas not producing insulin)
- Defects in the action of insulin. The pancreas produces the correct amount of insulin but the cells in the body are resistant to the action of insulin. This results in the blood sugar being too high (hyperglycemia)
- Defects in both secretion and action of insulin.
Causes of DI?
- hypothalmic injury (trauma/surgery)
- effects of certain drugs like lithium on renal absorption of water
- sickle cell anemia
- hypothyroidism
- adrenal insufficiency
- inherited disorders of ADH
- sarcoidosis
Signs, symptoms of Diabetes Insipidus
DI is characterized by polyuria and thirst. If left untreated, dehydration may result in fever, vomiting and convulsions.
What is type 1 DM?
Type 1 – Also known as insulin-dependent diabetes or juvenile-onset DM.
produce little or no insulin
autoimmune, genetic and environmental factors are involved in this type of diabetes.
what is type 2 DM?
Known as non-insulin-dependent diabetes or adult-onset DM.
inadequate insulin, production
most common in obese individuals over the age of 40 with a marked family tendency
usually responds to oral hypoglycemic medications and to changes in diet and lifestyle
2 Kinds of diabetic crises:
- Diabetic coma – Too little insulin (hyperglycemia)
- Insulin reaction – Too much insulin (hypoglycemia)
What is DKA and who is most likely to have it?
When excess ketone bodies appear in the blood, diabetic ketoacidosis (DKA) develops. The body attempts to compensate for the acidosis by hyperventilation and the loss of minerals and water in the urine. When the blood glucose is very high, sugar also “spills over” into the urine. DKA is most common with Type 1 DM.
Signs and symptoms of mild to severe hyperglycemia:
- Terribly thirsty
- Frequent and copious urination
- Breath that smells fruity or sweet
- Decreased appetite
- Nausea, vomiting
- Weakness
- Confusion
- Coma
How is hypoglycemia managed in an alert and cooperative patient?
the rapid delivery of a source of easily absorbed sugar such as juice, pop or a prepackaged dose of glucose (which is placed inside the cheek)
How is hypoglycemia managed when it is severe or patient is unconscious?
a parenteral injection of 0.5 to 1.0 mg of glucagon may be ordered. An IV infusion of dextrose solution could be necessary if the patient doesn’t respond to the glucagon
Signs and symptoms of mild to severe hypoglycemia:
- Sudden onset of weakness
- Sweating, tremors (quivering)
- Hunger
- Cold, clammy skin, diaphoresis
- Headache
- Tachycardia
- Impaired vision
- Personality change, agitated and nervous
- Loss of consciousness
what is gestational diabetes
Gestational diabetes can occur temporarily during pregnancy. Significant hormonal changes can lead to blood sugar elevation in genetically predisposed individuals. It usually resolves once the baby is born.
Common Medical Emergencies that occur in the Diagnostic Imaging (DI) dept. include:
- Seizures
- Vertigo/Orthostatic Hypotension
- Nausea and Vomiting
- Cerebrovascular Accident (CVA)
- Syncope/Fainting
- Drug Reaction
- Contrast Media Reaction
- Shock
- Diabetes
Common causes of seizures:
Often occur as a sudden onset of disease or illness (e.g., stroke) or as a symptom of an underlying issue (e.g., epilepsy or alcohol withdrawal).
three common types of seizure:
- Major Motor seizure
AKA (tonic-clonic or grand mal)
– Most common “generalized” seizure, involving electrical activity in entire brain. Patient may experience as aura or premonitory sign. Characterized by a hoarse cry, convulsions and loss of consciousness.
three common types of seizure:
- Absence seizure
AKA (petit mal)
– Also a generalized seizure. Involves brief loss of consciousness where patient stares blankly and may lose balance and fall. Many patients are unaware that they undergo this loss of consciousness. There are no convulsions and patient is often unaware of seizure occurring. Common with children.
three common types of seizure
Partial (focal) seizure:
- Can be simple or complex, depending whether patient loses awareness. These seizures can have motor, autonomic, sensory or psychological symptoms. May cause severe uncontrollable tremors and often is caused by extreme anxiety and hyperventilation in a conscious patient. These seizures are exhausting to the patient and may persist for more than an hour.
First duty during a patient’s seizure?
Keeping patient safe; placing padding under the head, preventing any falls
What should be monitored during a patient’s seizure?
Monitor rate and quality of respiration.
Monitor patient’s airway but do not place anything in the mouth or between the teeth. Do not attempt to grasp or position the tongue.
When convulsions subside, what should the radiographer do with the patient?
- turn the patient into the recovery position (i.e., Sim’s position) in case vomiting occurs. Careful if pt. on x-ray table that they don’t fall.
- Allow patient to rest afterwards.
