CSTR Exam Questions and Correct Answers
Question 1
How can results be reported for PI loop closure?
Correct Answer
By tracking and reporting data demonstrating the successful implementation of
corrective action plans.
Question 2
What are examples of documentation to look for indicating injury to the face?
Correct Answer
Facial fractures: Broken bones in the facial structure.
Lacerations: Cuts or wounds on the face.
Abrasions: Scratches or skin damage.
Ecchymosis: Discoloration or bruising
Deformities: Visible changes in facial shape
Question 3
What is used to measure variability of a data set, calculated as the square root of the
variance of a set of data?
Correct Answer
The standard deviation.
Question 4
Understand the documentation specific to burns.
Correct Answer
Documentation for burn injuries should include a detailed patient history, a
comprehensive burn assessment, and ongoing documentation of treatment and
healing progress. This involves recording the mechanism of injury, burn location,
depth, total body surface area (TBSA), and any pre-existing conditions or
medications.

,Question 5
Give examples of fluid management.
Correct Answer
1. Resuscitation:
Crystalloid fluids: Normal saline (0.9% NaCl) is a common choice for restoring fluid
volume and electrolytes in patients experiencing shock or hypovolemia.
Colloid fluids: Albumin may be used in addition to crystalloids, particularly in
patients who don't respond well to crystalloids or have hypoalbuminemia.
2. Maintenance:
Isotonic solutions: Dextrose solutions in saline (e.g., D5NS) or dextrose 5% in water
(D5W) are used to provide carbohydrates and maintain fluid volume in patients who
cannot take oral fluids.
3. Replacement:
Hypotonic fluids: Half-normal saline (0.45% NaCl) can be used to treat intracellular
dehydration, such as in diabetic ketoacidosis.
Hypertonic fluids: D5NS is an example, used in specific situations, like treating
hyponatremia, where the goal is to pull fluid out of the cells and into the
bloodstream.
4. Other Examples:
Oral rehydration: For mild to moderate dehydration, oral rehydration solutions
(ORS) are often the preferred method.
Feeding tubes: In cases where patients cannot tolerate oral intake, feeding tubes
can deliver fluids and nutrients.
Question 6
What is data entry validation used to measure? What are some ways measure this?
Correct Answer
Ensures the accuracy and completeness of the data.
-Data Validation Reports
-National Trauma Data Standard (NTDS)
-Edit Checks
-Data Quality Dimensions
-Re-abstraction
-Focus on Key Fields
-TQIP (Trauma Quality Improvement Program)

,Question 7
What is the ICD 10 diagnostic code range injury exclusion criteria?
Correct Answer
• S00 (Superficial injuries of the head)
• S10 (Superficial injuries of the neck)
• S20 (Superficial injuries of the thorax)
• S30 (Superficial injuries of the abdomen, pelvis, lower back and external genitals)
• S40 (Superficial injuries of shoulder and upper arm)
• S50 (Superficial injuries of elbow and forearm)
• S60 (Superficial injuries of wrist, hand and fingers)
• S70 (Superficial injuries of hip and thigh)
• S80 (Superficial injuries of knee and lower leg)
• S90 (Superficial injuries of ankle, foot and toes
Question 8
What five components of an injury does the ICD 10 External Cause code capture?
Correct Answer
1. the cause of the event
2. the intent
3. the place where the event occurred
4. the activity of the person at the time
5. the person's status
Question 9
How was a uniform data set for inclusion criteria determined?
Correct Answer
The uniform data set for inclusion criteria in the National Trauma Data Bank (NTDB)
was established through the development of the National Trauma Data Standard
(NTDS). The NTDS, spearheaded by the American College of Surgeons (ACS)
Committee on Trauma, defines a standard set of trauma registry variables and their
definitions. This standard ensures consistent data collection across all hospitals
participating in the NTDB, regardless of their designation status. The inclusion
criteria are based on International Statistical Classification of Diseases, Tenth
Revision, Clinical Modification (ICD-10-CM) diagnosis codes and certain admission
characteristics.

, Question 10
What is the purpose of reporting?
Correct Answer
-to improve patient care
-conduct research
-support injury prevention efforts
Question 11
What is a data gap? Give an example.
Correct Answer
Missing or incomplete information about a trauma patient, which can hinder
accurate data analysis and research. For example, a trauma registry might have
records where the mechanism of injury is not documented, or the patient's initial
vitals are missing.
Question 12
What does population analysis look at?
Correct Answer
Primarily examines the characteristics and trends of the injured population within a
specific geographic or demographic area. This involves looking at demographics
like age, gender, race, and ethnicity, as well as other factors like socioeconomic
status, injury severity, and mechanism of injury.
Question 13
Which injuries require an ICD-10 code?
Correct Answer
any injury requiring an ICD-10 code for accurate data tracking and reporting is
coded
