The approximate amount of aerosol deposited in the lower respiratory tract when delivering medication via pMDI with spacer is approximately: Incorrect 40% 15% 8% 25% Which of the following is the primary advantage of delivering medication via inhalation? Correct Inhaled drug therapy treats the lung directly with smaller doses, resulting in fewer side effects Inhaled drug therapy is less painful than injection Inhaled drug therapy is relatively comfortable Inhaled drug therapy is cheap Most hazards associated with aerosol therapy are attributed to which of the following? Incorrect Aerosol generator failure Adverse reactions to the medication Improper delivery technique Environmental problems Which of the following is a disadvantage of delivering inhaled drug therapy via SVN? Incorrect Drug concentrations can be modified Ability to aerosolized drug mixtures (>1 drug) if drugs are compatible Useful in very old, debilitated or distressed patients Treatment times may range from 5-25 minutes Nebulizers that use electricity to vibrate a piezo element that moves liquid formations through a fine mesh to generate aerosol are referred to as: Incorrect jet nebulizers ultrasonic nebulizers vibrating mesh nebulizers microprocessor-controlled breath-actuated nebulizer The respiratory therapist is delivering inhaled drug therapy to his patient with a jet nebulizer designed to operate at 6-8 L/min at 50 psi. The respiratory therapist delivers the inhaled drug therapy with a compressor that produces 13 psi. What is the anticipated impact on aerosol particle size? Incorrect Particle size will not be affected Particles smaller in size will be produced Particles larger in size will be produced No particles will be produced The component of the pMDI that is responsible for metering a reproducible volume or dose of medication is called the: Incorrect Actuator Canister Dose counter Metering valve Which of the following is an advantage of delivering inhaled drug therapy via pMDI? Correct Hand-breath coordination is required to use pMDI devices Foreign body aspiration from debris-filled mouthpiece is possible No drug preparation is required High level of oropharyngeal drug deposition When educating the patient on the use of her pMDI device and maximizing drug delivery, the respiratory therapist should encourage which of the following actions? Incorrect Pause for at least 10 minutes between actuations for effective therapy Clean the nozzle periodically based on manufacturer’s recommendations Never prime the pMDI as that wastes the medication Never shake the canister as it will produce foam The U.S. Department of Health and Human Services FDA requires new pMDI to: Incorrect Have integrated dose counters Be of standard size to fit third-party dose counters Have a calendar attached to manually count doses None of the above The difference between a spacer and a valved holding chamber is the presence of a low-resistance, one-way valve that allows aerosol particles to be contained within the chamber for a short time until an inspiratory effort opens the valve and medication is delivered. The major benefit to the valved holding chamber over a spacer is: Correct Prevents aerosol particles from exiting the chamber until inhalation begins Slows the aerosol velocity Reduces particle size Decrease oral deposition Which of the following is an advantage of delivering inhaled drug therapy via DPI? Correct A limited range of drugs are available in DPI formats Multiple types of DPI devices are on the market DPI devices have short preparation and administration times It is easy for patients to confuse directions between different DPI devices The respiratory therapist is educating a patient with COPD on the correct use of his DPI device. The patient is currently experiencing acute airflow obstruction and is unable to generate adequate inspiratory flow with the DPI. Which of the following results should the respiratory therapist expect in this situation? Correct The respiratory therapist should expect that the patient would receive more medication from the DPI.. The respiratory therapist should expect that the patient would receive less medication from the DPI. The respiratory therapist should expect that the patient would receive the prescribed amount of medication from the DPI. The respiratory therapist should expect none of the above. Which of the following methods will alert the user that the multi-dose DPI is empty? Incorrect Dispose of the single-use capsule after treatment. Visual inspection of the blister packet View the counter on the integrated dose counter Manually keep a calendar Why is it important to take patient preference for delivery device into consideration when selecting an aerosol generator? Correct To make the patient feel valued To make the decision easier for the respiratory therapist Patients like to be asked their preference Patients tend to use devices they prefer more regularly than devices they dislike When is blow-by therapy appropriate? Correct When the child is crying When the child is held by his/her mother When the respiratory therapist doesn’t want to wake the child Blow-by therapy is not supported as a viable delivery method by the evidence In the home, what is the most effective way to clean nebulizers? Incorrect Wash with soap and water after every treatment Soak in 70% isopropyl alcohol for 5 minutes daily Soak in 3% hydrogen peroxide for 30 minutes daily Soak in vinegar/water solution for one hour after every treatment Protective measures for respiratory therapists who deliver inhaled drug therapy include: Incorrect Health assessment and immunization Hand hygiene Filtered nebulizers All of the above Which of the following is an unintentional factor affecting patient adherence to prescribed inhaled drug therapy? Incorrect The patient does not believe that he/she requires regular medication The medication is too expensive The patient does not perceive a benefit from the medication The patient misunderstands the prescribed drug regimen To educate the patient with low health literacy, it is important to: Incorrect Speak very slowly Use pictures with written instructions Make them come back to the office more frequently for monitoring None of the above are helpful when educating a patient with low health literacyYou have failed attempt 1 of 2 to pass this quiz.

Explanation / Answer
Please find the answers and explanations below:
Answer 1: Choice 1 (the lung/pulmonary deposition of these inhalers can range broadly fro 1-50% depending upon the manufacturer and dose. The maximum limit lies to 50% with present technologies. Thus, choice 1 is correct because it gives the maximum possible deposition)
Answer 2: Choice 1 (When a drug against pulmonary maladies is directly inhaled, there are maximum chances that the drug will reach directly to the area of interest and perform phamacological function over there. Since the drug will not travel whole body via circulation or intra-peritoneal injections, there are minimized chances of side effects using intra-nasal drugs)
Answer 3: Choice 4 (although aerosol are routinely used in commercial and household items such as deodrents, they generate environmental problems as well as associated with multiple health hazards are associated with poor sanitation, digestive tract problem, increasing irritability, generation of poisonous gas content in air, hypersensitivity etc)
Answer 4: Choice 4 (SVN or small volume nebulizers are very good means of providing inhalation drugs to patients which do not show much physical cooperation. However, since a very small amount of dose is used, the reaction time is generally high in such treatments thus relief from the ailment is delayed, say 5-25 minutes.)
