CORRECT ANSWERS | A+GRADE

The respiratory therapist notes in the medical record ofia 65-year-
i i i i i i i i i


old male that the patient is ordered to receive bronchodilator therapy with Albuterol. The thera
i i i i i i i i i i i i i i


pist also notes the patient is receiving beta-
i i i i i i i


blocker medication. The therapist should recommend i i i i i


A. Administer Dexamethasone (Decadron) in place ofi Albuterol
i i i i i i i i


B. Add Xopenex to the bronchodilator regimen
i i i i i i i


C. Replace Albuterol with Beclamethasone (Beclovent)
i i i i i i


D. Switch from Albuterol to ipratropium bromide (Atrovent) - D.
i i i i i i i i i i



Because albuterol is a beta-agonist medication, patients who are taking beta- i i i i i i i i i i



blockers should utilize other bronchodilation medication. i i i i i




A hospital has an extremely low incidence ofi ventilator-
i i i i i i i i


associated pneumonia. To which ofithe following reasons may this be attributed? i i i i i i i i i i


A. periodic discontinuation ofi sedation
i i i i i


B. use ofi respiratory precautions with the population
i i i i i i i i


C. diversion ofi infectious patients to other facilities
i i i i i i i i


D. broad use ofi prophylactic antibiotics - A.
i i i i i i i i


The incidence ofi ventilator- i i i



associated pneumonia, or VAP, is lowered by using a closed system suction catheter, i i i i i i i i i i i i i



periodically discontinuing sedation, keeping the patient and semi- i i i i i i i



Fowler's position, and proper handwashing among caregivers. All are correct. i i i i i i i i i




A pressure-
i


volume loop ventilator graphic shows no rise in pressure for the first 200 mL ofidelivered volu
i i i i i i i i i i i i i i i


me. The therapist should i i i


A. increase inspiratory flow rate
i i i i i


B. increase PEEP
i i i


C. decrease tidal volume
i i i i


D. decrease inspiratory flow rate - B.
i i i i i i i



In this question the description ofi the pressure volume loop would indicate a flat bott
i i i i i i i i i i i i i i



om as manifested by no rise in pressure with the first 200 mL ofidelivered volume. We c
i i i i i i i i i i i i i i i i



all this a "flat football". The solution is to increase PEEP to a level that the pressure beg
i i i i i i i i i i i i i i i i i



ins to rise immediately as volume is introduced.
i i i i i i i




Which ofi the following would be the most effective, appropriate method for resolving atelecta
i i i i i i i i i i i i i


sis in a spontaneously breathing, post operative patient who is under the influence ofisedatio
i i i i i i i i i i i i i


n and will not respond to verbal stimuli?
i i i i i i i


A. IPPB
i i


B. sustained maximal inhalation (incentive spirometer)
i i i i i i


C. deep breathing coaching
i i i i


D. intubation and mechanical ventilation - A.
i i i i i i i



A postoperative patient under sedation, and possibly in pain, may be tempted to breat
i i i i i i i i i i i i i

,he less, causing respiratory acidosis and atelectasis. To correct this problem, IPPB th
i i i i i i i i i i i i



erapy

,is most appropriate. Incentive spirometry would also help but the patient is unable to r
i i i i i i i i i i i i i i



espond to verbal stimuli. This alone is an indication for IPPB therapy.
i i i i i i i i i i i




After performing minimum occluding volume technique with a 65-kg (143-
i i i i i i i i i


lb) patient who is orally intubated with a 7.0-
i i i i i i i i


mm ET tube, the respiratory therapist should NEXT
i i i i i i i


A. check ET tube cuffi pressure
i i i i i i


B. perform tracheal palpation
i i i i


C. order a chest radiograph
i i i i i


D. document ET tube markings at the lips - A.
i i i i i i i i i i



The ET tube cuffipressure may be adjusted correctly by several techniques including
i i i i i i i i i i i i



minimum leak technique (also called minimum occluding volume, minimal seal techni i i i i i i i i i i



que, and the use ofia pressure manometer called a cuffalator. Ifiminimum seal or mini
i i i i i i i i i i i i i



mal leak technique is used, the respiratory therapist is still required to monitor the pres
i i i i i i i i i i i i i i



sure after the technique is performed. Although this is often not done in real life, it is tec
i i i i i i i i i i i i i i i i i



hnically part ofithe procedure. i i i




The respiratory therapist observes an ECG wave form on a patient that is consistent with atrial
i i i i i i i i i i i i i i i i


tachycardia. The patient is complaining ofi chest pain, dizziness, and nausea. The respirator i i i i i i i i i i i i


y therapist should recommend
i i i


A. unsynchronized defibrillation
i i i


B. Atropine sulfate
i i i


C. epinephrine
i i


D. cardioversion - D.
i i i i



Non-
deadly arrhythmias, such as this one, may be addressed through cardioversion. Ca
i i i i i i i i i i i



rdioversion is a form ofi defibrillation with low wattage and with the synchronizatio i i i i i i i i i i i i



n set to "active". This allows the shock to be synchronized to the R wave.

This patient has a CO2 ofi42 mmHg, which suggests adequate ventilation. However, t
i i i i i i i i i i i i



he high pH is associated with alkalosis. Because the CO2 is normal, the cause ofi the al
i i i i i i i i i i i i i i i i



kalosis must be metabolic in nature. One treatment for metabolic alkalosis is to admin
i i i i i i i i i i i i i



ister potassium chloride or KCl. i i i i
