Q

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?

A
  1. Look for cyanosis (bluish color in the skin).
  2. Caused by lack of oxygen in the tissues.
  3. Easily seen on mucous membranes such as lips and lining of the mouth.
  4. If a patient looks pale and anxious and states they “do not feel well,” the technologist should NOT leave the patient.

Q

Skin Temperature:

What does contact through touch allow? What characteristics does an acutely ill person in pain likely display?

A
  1. Contact through touch also allows ongoing physical observation.
  2. Acutely ill patient who is in pain is likely pale, cool and diaphoretic (i.e., cold sweat).

Q

What is DM?

A

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.

Q

What is DKA and who is most likely to have it?

A

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.

A
  • patient may be having a TIA (transient ischemic attack) or CVA (cerebrovascular accident).
63
Q

How can vomiting sometimes be prevented?

A

by radiographer’s reassuring presence and breathing instructions (“breathe through your mouth and take short, rapid, panting breaths” OR “slow breaths through the nose”)

64
Q

What position should the patient be in when experiencing nausea and vomiting? Why?

66
Q

radiographer’s response to stroke (5 points)

A
  • Report symptoms even if only temporary to a physician. The most promising outcome of a stroke occurs if patient receives treatment within 1 hour of onset.
  • Place patient in recumbent position with head elevated.
  • Seek assistance but do NOT leave the patient unattended.
  • Have crash cart and oxygen nearby.
  • Monitor vital signs every 5 minutes or follow physician’s orders.
67
Q

What is syncope (fainting)? What are potential causes?

A
  • a temporary loss of consciousness and postural tone caused by diminished cerebral blood flow,
  • usually due to low blood pressure.
  • considered a mild form of shock
  • can occur when fear, pain or an unpleasant event are beyond the coping ability of the patient’s nervous system.
  • Can also be caused by overheating, dehydration, exhaustion, sudden changes in body position or as a result of medications.
68
Q

Radiographer’s Response to Syncope: (6 points)

A
  • No physician order is required if patient remains conscious/aware.
  • Place patient in sitting or recumbent position, elevating the feet to return periphery circulation to the major organs/brain. (recumbent best position for this to occur)
  • Patients that have fasted for tests may become hypoglycemic. In this case, provide food/sugar/juice.
  • Reassure patient to alleviate stress or anxiety.
  • Spirits of ammonia can be held under nose to bring patient to consciousness.
  • Patient should be assessed by physician if consciousness is lost for more than a minute or two.
69
Q

What example does the medical emergencies handout give of an exam that cannot have any extra amount contrast injected prior to the test itself?

A

CT scan of kidneys

70
Q

What is believed to contribute to the risk/ frequency of contrast reactions?

A
  • Large amounts of contrast injected at high rates (3–5cc/min)
  • there is a greater risk of reaction associated with IV administration than with arterial injections.
  • anxiety
71
Q

What is important to discuss with the patient before a contrast injection and why?

A
  • Anxiety has been linked to reactions
  • explain Common sensations felt by patients after contrast media injections
    • feeling warm or flushed
    • metallic taste
    • the sensation of urinating
    • nausea and/or vomiting (linked to the amount and speed of injection given)
  • also we learned in CT all potential side effects need to be discussed with the pt which, wouldn’t that increase their anxiety? meh
72
Q

What does the handout classify as a mild to moderate contrast reaction?

A
  • Itchy skin
  • Development of urticaria (hives) or other skin rash
  • Nasal congestion, sneezing, watery eyes
  • Coughing with possible laryngeal swelling
  • Peripheral tingling
  • Tachycardia (more than 100 beats/min) OR Bradycardia (less than 60 beats/min)
  • Hypotension
  • Feeling of fullness or tightness of chest, mouth or throat
  • Feeling of anxiety or nervousness
73
Q

Radiographer’s response to Mild/Moderate Reaction: (6 points)

A
  • Calm and reassure the patient.
  • Identify the allergen and avoid further contact (stop injection and exam).
  • Apply cool compress to itchy areas.
  • Observe the patient for sign/symptoms of increased distress or changes.
  • Document details of reaction in patient’s electronic profile, on the requisition and in patient’s chart.
  • Obtain medical assistance. Consult with radiologist and/or physician/nurse to determine necessary observation of patient before patient is discharged.
74
Q

what does the handout classify as a severe reaction to contrast?

A
  • Abrupt onset
  • Bradycardia (less than 50 beats/min)
  • Hypotension (decrease in BP)
  • Severe dyspnea
  • Cardiac arrhythmias
  • Laryngeal swelling
  • Possible convulsions/seizures
  • Loss of consciousness
  • Respiratory arrest or cardiac arrest
75
Q

Radiographer’s Response to Severe Contrast Reaction: (6 points)

A
  • Maintain airway and call a code.
  • Calm and reassure the person.
  • stop any infusion or injection and ensure integrity of the IV site, which may be used to give medication to treat reaction.
  • Prepare oxygen, suction and crash cart.
  • Have patient’s history ready and available.
  • Be ready to assist physician(s).
76
Q

How often should each crash cart be inspected? By who?

A

Daily to ensure supplies are stocked and meds not expired by Code team nurses

77
Q

The most important rule when it comes to crash carts is ?

A

NEVER borrow anything from a crash cart.

78
Q

9 Drugs Commonly found on crash cart and their uses

A
  • Adrenalin (epinephrine) – increases cardiac output, raises BP, acts as vasoconstrictor and relaxes bronchioles
  • Atropine – respiratory/circulatory stimulant, dries secretions
  • Dilantin (phenytoin) – anti-convulsant, anti-epileptic drug
  • Glucagon – reverses hypoglycemia
  • Heparin – inhibits blood coagulation
  • Sodium bicarbonate – combats acidosis
  • Sterile water – diluent
  • Valium (diazepam) – tranquilizer, anti-seizure agent
  • Xylocaine (lidocaine) – anesthetic, cardiac anti-dysrhythmic
79
Q

What 2 categories does the technologist need to be collecting accurate information about re: the patient?

A
  • The patient’s history
  • Patient’s present condition
80
Q

What 3 things from the powerpoint are listed as the purpose of taking an accurate and relevant pt history?

A
  • Avoid a incorrect exam being performed on the patient
  • Minimize the amount of radiation the patient receives
  • Efficiently use the equipment, contrast, etc. involved with the exam.
81
Q

Employ the following techniques to encourage expression and prevent the patient from wandering off the subject:

A
  • Open-ended questions
  • Facilitation
  • Silence
  • Reflection or reiteration
  • Clarification or probing, but don’t “lead on”
  • Summarization
82
Q

How should radiographer start when taking a patient history? What does this accomplish?

A
  • Start taking a history by asking a general question (“Do you know why your Dr. ordered these x-rays of your hip?”)
  • Can confirm history/reason for x-ray, clarify the correct side and reduce exposure dose.
83
Q

To obtain the greatest amount of data in the least amount of time and to help avoid missing relevant information, what are some relevant questions to direct to the patient?

A
  • Onset of condition/pain (how did it start?)
  • Duration/frequency of condition
  • Specific location of pain/issue
  • Quality of pain (sharp or dull?)
  • What aggravates condition/pain?
  • What alleviates condition/pain?

basically how, when, where, what kind, what worsens, what helps

84
Q

Why would a radiographer want top establish a baseline for their observations about a patient’s condition?

A

To assess change

85
Q

When should radiographer assess the pt condition?

A

before, during and after procedures/exams

  • respiratory tract
105
Q

7 step response to anaphylactic shock:

A
  1. Do not leave the patient, Stop any infusion or injection of contrast immediately, however you MUST maintain the IV line for medication access.
  2. Notify the radiologist or ER physician (check site’s protocol)
  3. If patient complains of respiratory distress or has any of the symptoms listed in the severe reaction section- call the Code Team
  4. Place patient in semi-Fowler position or sitting position to facilitate respiration if possible
  5. Monitor pulse, respiration and blood pressure every 5 minutes until Code team arrives or the physicians orders state otherwise.

Q

What factors affect HR?

A
  • Age
    • Infants have the highest average pulse rate at 140 bpm
    • Elderly have the lowest at 50–65 bpm
  • Gender
    • Females generally tend to have higher pulse rates than males of the same age
  • Emotions
    • Stress, anxiety, excitement and being frightened all contribute to an increased heart rate/pulse rate
  • Temperature
    • Working out in a hot climate or having a fever increases pulse rate
  • Posture
    • Standing and sitting up require more energy than lying down
  • Activity
  • Exercise increases body’s need for oxygen and nutrients, thereby increasing heart rate
  • Medication
  • Drugs such as amphetamines and decongestants may speed up the heart rate, whereas others cause a decrease
  • Stimulants
  • Caffeine and cigarettes speed up the heart rate
  • Alcohol
  • Vasodilators lower blood pressure, so heart rate increases to maintain sufficient blood flow
  • Music
  • Researchers believe that music can affect the heart rate. Upbeat types of music may cause increased pulse, whereas classical types of music may lower pulse
