| Question | Answer |
|---|---|
| Most appropriate position for a patient with extremely low blood pressure | Trendelenburg |
| Patient is supine on a surface inclined 45 degrees, head at the lower end and legs flexed over the upper end. | Trendelenburg Position |
| The head of the patient's bed is raised 18–20 inches above the level, with the knees also elevated. | Fowler's position |
| fowlers position | Head up decreases venous return |
| Sims | Lateral position |
| During a bronchoscopy, what should be monitored | ECG pattern Pulse oximetry |
| An inverse I:E ratio appears after initiation volume-controlled ventilation. This could indicate.. | Inspiratory Flow is low (to fix) increase flow, decrease volume or RR |
| Inverse I:E Ratio | I-time exceeds E-time |
| Leukotriene inhibitors, such as montelukast (Singulair), are indicated to control of | mild asthma and allergic rhinitis. |
| A colorimetric capnometer is used for | confirming proper tube placement by identifying the presence of CO2 following endotracheal intubation |
| A galvonic analyzer is used to assess .... | oxygen concentration |
| When in the proper position, the tip of the CVP catheter should be in the .... | lower portion of the superior vena cava |
| Reduced MIP indicates | decreased muscle strength |
| Decreased Tidal Volume indicates | decreased muscle strength |
| Decreased Vital Capacity indicates | decreased muscle strength |
| The correction factor for 80%/20% heliox is | 1.8 |
| Best device to administer a controlled oxygen concentration for a patient with a variable respiratory pattern.... | air-entrainment mask |
| Air-entrainment mask can provide a high enough total flow to ..... | exceed the patients peak inspiratory flow and ensure consistent oxygen concentration |
| Lactic Acidosis characterized by | high ion gap acidosis commonly from an acute process (ex) Hypoxia |
| What steps should be included in a cleaning procedure for equipment for an outpatient... | Remove soap by rinsing with water Soak in a vinegar solution for 20 minutes drain dry without wiping |
| soap should be rinsed away to prevent | irritation to the mucusa |
| vinegar is an effective disinfectant for... | common pathogens |
| Air drying is less likely to result in ... | contamination than wiping which can produce pathogens |
| Water in the tubing imposes a back pressure on air entrainment resulting in ... | a decrease in air entrainment and increased FIO2 |
| The air-entrainment setting is 40%, but the oxygen analyzer reads 60%. What could be a cause... | The analyzer could be improperly calibrated water in the tubing could be reducing gas flow |
| Converting from an HME to a heated humidifier increases.... | water vapor content and improved mucociliary function |
| Best way to check the accuracy of a water seal spirometer | 3L syringe (only equipment that provides accurate volumes for calibration) |
| The physiologic goal of CPAP in atelectasis is to .. | Increase FRC (functional residual capacity) |
| CPAP increases FRC by... | stabilizing alveoli at end-inspiration and preventing their collapse |
| A patient has an adverse reaction during administration of routine therapy.... | Notify the nurse who is responsible for the patient record patients reactions in chart contact the physician if a change in therapy seems warranted |
| Morphine sulfate | diminishes the effects of pain acts as a sedative |
| Lukens's trap | designed to collect sputum during suctioning |
| Carlen's tube is a | double lumen endotracheal tube |
| Nocturnal dyspnea and coarse crackles are indications of ... | congestive heart failure |
| Hypertension can be a factor for | heart failure |
| Diuretics are useful in ... | controlling water retention that can lead to fluid accumulation and narrowing in airways |
| Small amounts of thin white sputum are obtained during suctioning. What should the RT do next? | suction the patient without saline instillation (saline is not necessary if secretions are easily removed and it may cause airway infection) |
| Kussmauls Breathing | increased rate of breathing increased depth of breathing (rapid deep breathing) |
| Kussmauls Brething is commonly a result of a | diabetic crisis (ketoacidosis) |
| Cheyne-strokes brething | irregular breathing with periods of apnea |
| Bronchospasm is is the most frequently reported adverse affect associated with the administration of... | aerosolized pentamidine isethionate (NebuPent) |
| The oxygen concentration measured is 42% on an air-entratinment mask on a patient recieving 35% oxygen... | Assess the patnecty of the air-entrainment ports |
| The determinants of FIO2 on air entrainment mask are the ... | jet size size of the entrainment ports |
| Any obstruction to the air entrainment port will | increase the FIO2 by decreasing the volume of the air entrained |
| The therapist determines the patients endotracheal tube is in the right mainstem bronchus after auscultating the patients chest. What should the RT do? | withdraw the tube until breath sounds are heard equal bilaterally record this action in the patients chart |
