tmc practice test QUESTIONS ACCURATE AND VERIFIED ACTUAL EXAM QUESTIONS WITH DETAILED ANSWERS FOR GUARANTEED PASS | ALREADY GRADED A

During the aerosol therapy with a metered dose inhaler (MDI) without a spacer, the respiratory therapist instructs the patient to hold the mouthpiece approximately 1 inch away from the mouth. The therapist explains that this will: A. Help with the ordination of canister actuation B. reduce the likelihood that the drug will be deposited at the back of the throat C. enhance particle stability D. deliver a smaller sized particle to the deeper recesses of the lungs - ANSWER ANS: B. _ reduce the likelihood that the drug will be deposited at the back of the throat EX: my holding the mouthpiece 1 inch away from the mouth there is an increase in the distance between the aerosol in the back of the throat. This makes it more likely that the aerosol particles will remain in the inspired gas and travel into the lungs instead of depositing out in the back of the throat. Ideally, a 1 - point calibration is performed on a blood gas analyzer: A. At least once every 50 blood gases B. at least once every 8 hours C. prior to each sample analysis D. at least once in a 24 - hour period - ANSWER ANS: C. - Prior to each sample analysis A patient's PaO2 measured by blood gas analysis is to 255 mm HG. The blood gas analyzer on which the sample is analyzed is calibrated to a PO2 of 150 mm HG. Which of the following is the most acceptable action? A. The patient's value is accurate, reported to the physician B. correlate the accuracy of the value via tonometry C. recalibrate the blood gas analyzer to accommodate this unusual value D. reanalyze the blood gas sample on a different analyzer - ANSWER ANS: C. - recalibrate the blood gas analyzer to accommodate this unusual value EX: when the patient's PaO2 is considerably higher than the calibrated range of a blood gas analyzer, the analyzer should be recalibrated to accommodate this unusual value (using "calibration override "function and high oil 100% oxygen standard gas). Blood gas analyzer troubleshooting should be initiated when: A. The analyzer takes more than 30 seconds to complete its analysis B. quality control results are outside predefined acceptability limits C. an existing analyzer is replace D. calibration verification has not been completed - ANSWER ANS: B. - quality control results are outside predefined acceptability limits EX: troubleshooting should be indicated when quality control results are outside predefined acceptability limits. The remaining options do not decay a malfunction of the blood gas analyzer. The most important aspect regarding quality control for blood gas analysis is that: A. The blood specimen is properly labeled, stored, and analyzed within an acceptable period of time B. the blood gas analyzer is functioning properly prior to patient sample analysis C. blood gas testing is carried out according to an established prison protocol D. calibration of the blood gas analyzer is carried out every 8 hours - ANSWER ANS: B. - the blood gas analyzer is functioning properly prior to patient sample analysis EX: calibration, labeling and storing the blood specimen, and testing according to protocol are important considerations concerning blood gas analysis, however, they are of no consequence if the blood gas analyzer is not functioning properly prior to patient sample analysis. 109 Which of the following best describes the reason why masks are worn by practitioners who care for hospitalized patients that have a contagious airborne disease? A. They are designed to prevent bodily contact with the patient B. they are designed to protect the patient from practitioners who have a cold C. they are designed to prevent exhaled moisture from becoming contagious D. they are designed to filter most airborne species of bacteria - ANSWER ANS: D. - They are designed to filter most airborne species of bacteria EX: In the case of patients that have a contagious airborne disease, masks are worn by a practitioner to protect the practitioner from the patient's airborne disease by filtering out the airborne bacteria from being briefed by the practitioner. A respiratory therapist is asked to instruct the patient recently diagnosed with asthma white performing and recording peak flow measurements are important. The therapist should tell the patient: 1. Peak flow measurements help your doctor decide if your asthma is under control 2. if the peak flow meter is used every day at home, you can find breathing problems even before you start to release or cough 3. a drop in peak flow is a good way to recognize early signs of a coming asthma attack 4. it helps to see how bad asthma is 1, 2, and 3 only 1 and 3 only 1, 2, 3, and 4 2 and 4 only – A NSWER ANS: 1, 2, 3, and 4 EX: all of the options listed are important reasons why and asked the patient should perform and record peak flow measurements. While reviewing the patient's chart prior to administering and albuterol (Proventil) treatment, the respiratory therapist notes that the patient is scheduled for pre— bronchodilator and post - bronchodilator spirometry in one hour. The respiratory therapist should do which of the following? A. Tell the patient that he will get the treatment in one hour B. notify the pulmonary function laboratory of the conflict in therapy C. administer the treatment as ordered D. administer the treatment with normal saline only - ANSWER ANS: B. - Notify the pulmonary function laboratory of the conflict in therapy EX: because the patient will receive a bronchodilator by the pulmonary function technician within an hours time span and the patient is scheduled to receive a bronchodilator now, there is a conflict in therapy. The practitioner needs to consult the pulmonary function lab and ascertain whether the patient should receive the albuterol treatment now and have the pulmonary function lab reschedule that spirometry test or whether the patient can wait one hour and received a bronchodilator during the spirometry tests. It would be inappropriate to perform any of the remaining options A patient with allergic asthma has been prescribed albuterol (Proventil), nedocrmil sodium (Tilade), and flunisolide (Aerobid). The respiratory therapist should provide the patient with which of the following information? 1. Albuterol and nedocromil do not interact 2. during an acute asthmatic attack, take flunisolide 1st 3. nedocromil should not be taken during an asthmatic attack A. 1 in 2 only B. 1, 2, and 3 C. 2 and 3 only D. 1 and 3 only - ANSWER ANS: 1 and 3 only: hero and nedocromil do not interact, nedocromil should not be taken during an asthmatic attack EX: 1. TRUE - based on manufacturer guidelines, albuterol and nedocromil do not have any ingredients that interact with each other. 2. FALSE - during an acute asthmatic attack, the patient needs to administer the fast acting bronchodilator (albuterol) 1st. Flunisolide is not a bronchodilator and will not really bronchospasm. 3. TRUE -nedocromil is a mast cell stabilizer only. It is not indicated for use during an acute asthmatic attack because it has no therapeutic value when the mast cells are in an acute unstable phase. 103While assessing a patient to determine if respiratory treatments are indicated, the patient tells the respiratory therapist that he becomes short of breath when lying down, but when he sits his breeding is fine. Which of the following terms should the therapist record in the patient's chart that would best describe the patient's statement? A. platypnea B. Tachypnea C. Dyspnea D. orthopnea - ANSWER ANS: D. - orthopnea EX: orthopnea is a condition in which the patient feels discomfort in breathing while lying down and must sit upright to relieve the difficulty in breathing. Tachypnea means a rapid respiratory rate. Platypnea mean discomfort in breathing while in the upright or seated position. Dyspnea is a generic term that simply means difficulty in breathing. Dyspnea may I may not occur in any body position. 110Following the sterilization of respiratory equipment by Steve autoclave, heat sensitivity changes color. This indicates that: The equipment has been sterilized take the out dated conditions required for sterilization to occur have been met the equipment is not fully sterilized - ANSWER ANS: C. - conditions required for sterilization to occur have been met EX: a heat sensitivity changes color when exposed to a given temperature for a sufficient period of time. This indicates that the conditions required for sterilization to occur have been met. However, it does not sure the process is effective or the equipment is truly sterile. Only biological indicators can provide these assurances.
