TMC EXAM: Questions & Answers: Updated A+ Guide Solution

Romazicon (flumazenil) (Ans- -antidote for benzodiazepines such as -GABA receptor antagonist - It can treat drowsiness caused by sedatives following surgery or drug overdose. Which of the following can be used to estimate the level of Hemoglobin? (Ans- RBC -RBC X 3 = hemoglobin with the use of pressure control the most important alarm is (Ans- low volume -because the ventilator does not care about volume, the practitioner must. The most important alarm on a volume-cycled ventilator would be (Ans- high pressure alarm Which of the following would be most effective at resolving a humidity deficit for a patient who is intubated with an 8.0-mm endotracheal tube (Ans- wick or concha Which of the following would be most helpful for a patient with fixed upper airway obstruction? A. beta II agonist medication B. heliox therapy C. aerosolized epinephrine D. corticosteroids (Ans- B. heliox therapy Heliox therapy is most appropriate. Helium, when combined with oxygen, is less viscous than pure oxygen or room air, which is made up mostly of nitrogen. This allows patients to breathe in gases with less airway resistance. -fixed obstruction means it cannot be resolved simply with bronchodilators or other immediate methods. which one should be treated first, ventilation or oxygenation (Ans- ventilation the patient is over oxygenating AND hyperventilating which one should you treat first? (Ans- over oxygenation -To address over-oxygenation one can either change the PEEP or the FIO2. You will always want to lower the FIO2 below 60% before changing PEEP. ways to decrease CO2 (Ans- increase the Vt increase the rate remove dead space What would occur on a time-cycled ventilator with a fixed rate if the inspiratory flow rate were increased? A. increase in tidal volume B. decrease in inspiratory time C. decrease in tidal volume D. increase in inspiratory time (Ans- A. increased in tidal volume On a time-cycled ventilator inspiratory time is predetermined. So, if the flow rate is increased while the mandatory rate is unchanged, the result would be an increase in tidal volume. Which of the following is the most significant complication of bronchoscopy? A. laryngospasms B. hypotension C. vagal nerve stimulation D. coughing (Ans- A. laryngospasm -This tendency may be reduced by administering aerosolized Lidocaine or any other tissue numbing agent prior to the procedure.
