Unit 4 Flashcards
The collection of vital signs data is quick and noninvasive. The usual vital signs measured include
temperature, pulse, respiration, and blood pressure.
Body homeostasis is often referred to as the body’s “steady state” and is maintained by important body systems using physiologic feedback loops. Vital signs are an excellent indicator of the body’s response to conditions and therapies the patient is undergoing. A key strength of using vital signs as an indicator of homeostasis is that they
can be assessed quickly, and the data is objective.
All of the following are related except
Rectal
Inguinal*
Tympanic
Oral
All of the following are true of body temperature measurement except
all temperatures should be the same, regardless of where the temperature is measured.
A reliable device to measure oxygen saturation levels of arterial blood is a
pulse oximeter
A patient who has a temporal artery temperature of 100° F is
normal
The term bradypnea is used to describe
a decrease in respiratory rate.
The levels of blood pressures that are read on a sphygmomanometer are
systolic over diastolic
The flow rate of oxygen therapy is given in
liters per minute
To measure blood pressures, you will need a
stethoscope and sphygmomanometer
All of the following are true of oxygen therapy except
oxygen therapy can be prescribed by pharmacists and respiratory therapists
When taking a portable chest radiograph on a patient undergoing oxygen therapy,
the oxygen should not be removed without the consent of a physician or respiratory care practitioner.
All of the following are related except
thoracostomy tube*
Facial mask
Tent and oxy hood
Nasal cannula
The ideal location of the endotracheal tube tip is
in the trachea 1 to 2 inches above the carina.
The preferred location of a central venous line tip is the
superior vena cava.
Providing care in an emergency situation is intended to
1. prepare the injured patient for surgery.
2. prevent further harm to the patient.
3. preserve life.
4. place the patient into a sedated state for transport.
5. stabilize the patient until the appropriate medical assistance arrives.
2, 3, and 5
The single most important action for the radiologic and image science professional when administering emergency care is
providing a competent level of care, recognizing when advanced care is needed, and calling for assistance.
A common name for an emergency cart within medical imaging is the _____ cart.
crash
The medical term for a temporary suspension of consciousness is
syncope
What type of shock is caused by a failure of the heart to pump enough blood to the vital organs including the brain?
Cardiogenic
A 16-year-old patient comes to the diagnostic imaging department for a CT examination. He is lying on the table in a supine position and suddenly seems to lose consciousness and begins to move violently, with jerking motions. You realize that he is having a generalized seizure. The action that you must take is
go to the patient immediately, prevent him from harm and call for help.
The type of shock that is a result of severe blood loss is
hypovolemic
Symptoms of a head injury include
respiratory distress, a change in level of consciousness, and lethargy.
What type of shock can result from a severe reaction to the contrast media used in radiographic examinations?
Anaphylactic
Which of the following is most appropriate for a patient to counteract hypoglycemia?
Sugar-sweetened orange juice
After the administration of an iodine-based contrast into a patient, it is important for the radiologic and image science professional to observe the patient for
urticaria, nausea, shortness of breath, tightening in the throat, and cardiac arrest.
In patients who are hyperglycemic
insulin is required.
What type of shock is caused by loss of blood from a knife or gunshot wound?
Hypovolemic
For patients coming into the ER with a suspected penetrating abdominal stab wound or gunshot injury, a current Standard of Care is to quickly perform
a FAST sonographic scan series.
When comparing hyperglycemia with hypoglycemia, hyperglycemia
portrays clinical symptoms of excessive thirst and urination as well as dry mouth
What is the first thing you should do if a patient who is standing turns pale and states that they feel dizzy?
Have the patient lie down.
When caring for a patient with epistaxis, the patient
should lean forward and pinch their nostrils against the midline septum for several minutes.
An effective method to handle a patient with an asthmatic attack during a radiographic procedure would be to
have the patient sit down and allow the patient to use his or her aerosol inhaler.
As you are radiographing a patient from the emergency department who has a knife wound to the upper extremity, you notice that his wound dressing is becoming saturated with blood quickly, and he is getting lightheaded. You should
call for help, apply pressure to the wound site, and elevate their arm.
When working with burn patients, it is critically important to
use an extraordinary level of aseptic technique.
Current CPR Guidelines advocate what sequence of CPR steps?
Immediately begin compressions followed by ensuring an airway and ventilation.
When performing CPR as a single rescuer,
after each group of 30 compressions, give 2 quick ventilations
CPR can be stopped when
the rescuer is physically exhausted.
the patient responds and shows signs of recovery.
a physician says it’s time to stop CPR.
The Heimlich maneuver
is best achieved with increased intra-abdominal pressure through chest compressions.
A disorganized cardiac rhythm in which the ventricle “flutters” and loses cardiac output is called
fibrillation
An effective non-invasive method to deal with severe patient claustrophobia during MR examinations is to
provide a simple explanation of exam conditions and headphones to muffle the MR noise.
Adequate perfusion of human tissue generally requires
a systolic pressure of 90 mm Hg or greater.
All of the following are related except
myocardium
The QRS complex on a typical ECG represents
depolarization of ventricular muscle
If the PR interval is longer than normal on a typical ECG tracing, one can assume that
the patient has an AV node block
A widened QRS complex on an ECG tracing could represent
ventricular-paced rhythm
pacemaker tissue that is below the AV node
ventricular hypertrophy
Heart rates above 100 beats/min in an adult is termed
tachycardia
A cardiac arrhythmia that is life threatening and provides no effective cardiac output is
V-fib
An effective method for treating select cardiac arrhythmias is the use of high-frequency alternating current to destroy strategic cardiac tissue and reroute the cardiac impulses generated. These procedures are known as
cardiac ablation treatments
The T-wave of an ECG tracing represents
ventricular repolarization
Bonus Question- A dual-wire pacemaker places electrode tips in the
right atrium and right ventricle
Bonus Question- Cardiac output is a function of stroke volume and
heart rate
