RRT TMC EXAM 8 QUESTIONS WITH 100%
CORRECT ANSWERS!!
TMC Examination
160 Multiple-choice questions; 140 scored; 20 pretest items; 3 major content areas: Clinical data,
equipment, therapeutic procedures; 3 hour time limit; Track your progress #60 by the end of the
first hour; High cut score - 92, low cut score - 86.
Type of questions in TMC Examination
Recall - the ability to recall or recognize specific respiratory care information (33 questions);
Application - the ability to comprehend, relate, or apply knowledge to new or changing situations
(66 questions); Analysis - the ability to analyze information, put information together to arrive at
solution, or evaluate the usefulness of the solutions (41 questions).
RRT Examination (Clinical Simulation)
22 simulations; 20 count toward the grade; Scenarios are designed to flow just like a real patient
case; Branching logic format; 4 hour time limit; 6 per hour.
NBRC Matrix
The test matrix indicates the areas tested on the exams; This review is designed as a matrix based
approach; Provides example test questions and information pertinent to examination success.
Test Preparation Strategies
Study, study, study; BUT DON'T CRAM! Take as many practice exams as possible; Know
where the testing center is (consider traffic).
Test Preparation Strategies (Night Before)
Eat a good dinner the night before, avoiding alcohol; Do not cram the night before; Sleep well;
Plan to get up early with an alarm; Minimize caffeine.
Patient Data
(50 questions) Evaluate Data in the Patient Record (10 questions).
, Lung Compliance
CLD = tidal volume / (PIP - PEEP); CLS = tidal volume / (plateau - PEEP); When plateau
pressure increases with no change in tidal volume, lung compliance decreases.
Hypokalemia
Refers to a potassium level of <3.5 mEq/L; Usually results from diuretic therapy, vomiting,
diarrhea or severe trauma; Normal serum potassium (K+) level is 3.5 - 5 mEq/L.
Hypokalemia Clinical Symptoms
Muscle weakness resulting in respiratory failure, paralysis and hypotension; Cardiac arrhythmias
(PAC, PVC, V-tach); S-T segment depression on ECG.
Obstructive Lung Disorders
Pulmonary Function Results: Decreased flows (FEV1, FEF 25-75%); Increased FRC, RV, TLC;
An FEV1/FVC of < 70% will always indicate obstructive disease.
Restrictive Lung Disease
Pulmonary Function Results: Decreased volumes; Decreased capacities; Normal flow studies.
Response to Bronchodilators
Significant response to a bronchodilator indicated by: 12% or more increase in the FEV1 or FVC
posttreatment value-pretreatment value x 100 / pretreatment value; FVC increases by > 200 mL.
ABG Interpretation
pH 7.43; PaCO2 29 mm Hg; PaO2 70 mm Hg; HCO3 18 mEq/L; Fully compensated respiratory
alkalosis, mild hypoxemia.
Calculating Total Oxygen Content (CaO2)
Hb = 1.34 x Hb x SaO2; Plasma = .003 x PaO2.
Dynamic vs. Static Compliance
Dynamic compliance is always lower than static compliance because the PIP is used to calculate
dynamic compliance. Plateau is used to calculate static compliance.
