OMSA Recertification Exam QUESTIONS WITH COMPLETE 100% VERIFIED SOLUTIONS 2024/2025 Passage of air into lungs follows the course: Nose/mouth, nasopharynx, oropharynx, larynx, trachea palpebral The eyelash reflex is a form of the ____ reflex It is ok to use the patients family to watch the patient in recovery while we do the next procedure T or F False Elderly patients require _____medications than younger adults Less The trachea is _____ to the esophagus. When pt is supine the trachea will be ____ to the esophagus Anterior, Supine 3 questions to ask in recovery in this order 1. Does pt. need help maintaining airway? 2. What is their O2 sat. on room air? 3. Is the pt. awake? The stage of anesthesia where surgery can be performed is: 3 The most ideal airway management is Endotracheal intubation Pediatric pt. Mom calls saying Johnny came down with cold you should tell her Wait until pedo pt. gets better, then call us and we can schedule in 2 weeks Children have _____ heart rates and _____ blood pressure when compared to adults Higher, lower Side effect of succinylcholine to be careful of is: A muscle relaxant, side effects of Anectine include muscle relaxation resulting in respiratory depression to the point of apnea Bronchospasm tx is Beta 2 agonist such as albuterol & epinephrine Bronchospasm occurs when Constriction of smooth muscle walls of the bronchioles Your sedated pt. vomits mid-way thru procedure, what do you do Roll the pt to his right side and suction airway Treatment of respiratory depression is: Narcan 0.4mg/ml IV ASA guidelines for pre-op fasting -clear liquids: 2 hrs -breast milk: 4 hrs -infant formula, non-human milk, light meal (carbs only): 6 hours -before adult elective anesthesia: NPO after midnight Most surgeons prefer 8hr npo bronchospasm can de diagnosed by Expiratory wheeze and difficulty in positive pressure ventilation Narcan danger is Narcan May wear off before respiratory depressive effects of narcotics wear off laryngospasm Protective reflex closure of the vocal cords to prevent foreign materials from entering the lungs The most common cause if airway obstruction is Base of tongue falling back and occluding airway heart sounds MTAP The locations of best auscultation for each heart valve are labeled with "M", "T", "A", and "P". First heart sound: caused by atrioventricular valves - Mitral (M) and Tricuspid (T). Second heart sound caused by semilunar valves - Aortic (A) and Pulmonary/Pulmonic (P). Angina treatment Nitroglycerin (Nitro-bid, Nitrostat) -sublingual, oral, inhalant or transdermal patch. Used to prevent ischemia in stable angina, some variant used in acute attacks in all forms of angina. Side effects: headache, dizziness, orthostatic hypotension, nausea Precautions: Be aware of extreme side affects with acute, sublingual administration. Make certain patient has sublingual nitroglycerin. 60-100 bpm Your patient has an irregular irregular pulse. She most likely has: Atrial fibrillation Most common rhythm of cardiac arrest is: Ventricular fibrillation vagal maneuvers tx SVT, blowing on thumb (valsalva), ice to face, holding breath then bearing down, massaging carotid on one side of neck. if they do not work, give IV adenosine (antiarrythmic) First med for pt. In V fibb Epinephrine 1 mg IV A pt. having narrow complex tachycardia is complaining of chest pain. You notice bp falling and an altered level of consciousness your next move is Sedate pt then perform synchronized cardioversion 2nd med used in tx of V Fibb is Amiodarone T or F all bradycardia w/rate <50 should be given Atropine .5 mg False T or f you can defribillate asystole False Pt's in v fibb have a pulse t or f False Oxygen is carried by red blood cells Hairlike projections on the cells within the trachea are called Cilia - help move mucus and debris away from the lungs The _____ bronchus is straighter and wider than the ____ bronchus is narrower and more angles more acutely Right straighter wider Left narrow angled Order of airflow in upper respiratory system 1 nasopharyngeal 2 oropharnx 3 laryngopharynx 4 trachea Control of Respiration is dependent on The level of carbon dioxide in the blood Foreign bodies are usually aspirated down what mainstem bronchus Right because it is straighter Anatomical structure where cricothyrotomy is performed Through cricothyroid membrane Inspiration is more of an ____ process, where expiration is more of an ____ process Inspiration active Expiration passive gas exchange in lungs external respiration is exchanged in the alveoli lower respiratory system airflow order Trachea Right and left mainstrm bronchi Bronchioles Alveoli Rescue inhalers are usually Bronchodilators asthma is a disease of? Bronchoconstriction Pulse oximetry readings can be affected by all except Asthma meds don't affect Pulse oximetry factors 1)pt movement 2)fingernail polish 3)chronic exposure to nicotine Minimum amount oxygen during n20 22% O2 Asthma meds include and don't include Include: B2 agonist (bronchodilator Corticosteroids Antihistamines Don't include: A(Alpha) agonist LMA is the most ideal, preferred method of airway maintenance False Ideally pt should stop smoking for ____ before elective surgery 8 weeks or 2months Can you insert LMA on conscious pt. with intact gag reflex False normal adult respiratory rate on room air 96% at least Increase saliva is due to Stimulation of parasympathetic System Main organ that eliminates drugs Kidneys Main organ that processes drugs and changes chemical structure Liver Normally a nerve cell is polarized this means There are more positive ions on the outiside of the cell membrane and more negative ions on the inside Anesthetic agents act by Interfering with depolarization of the membrane The stimulus for respiration is Increasing co2 levels 2 components if the ANS are Parasympathetic and Sympathetic Nerve conduct impulses by Depolarization of the nerve membrane Nervous pt. You probably want to give this patient an anesthetic agent targeted at Center for emotion Increased heart rate and blood pressure are due to stimulation of the Sympathetic system Morphine is stronger than fentanyl. False Fentanyl is 80-100x stronger Nitrous Oxide (N2O) Is stored in blue tanks Produces euphoria and promotes relaxation Should always be used w/o2 Is non-flammable liquid Atropine, Glycopyrrolate two anticholinergics used as preanesthetics Sometimes given to reduce salivary secretions Steroids are used for reduction of tissue inflammation and swelling function of narcotics Minimize or eliminate pain Benzodiazepines are reverses by
