Exam 36: Aerosol Drug Therapy

For which of the following patient groups is use of a dry power inhaler (DPI) for bronchodilator administration NOT recommended? I.infants and children younger than 5 years II.patients with an acute bronchospastic episode III.patients requiring maintenance therapy

What is the retention of aerosol particles resulting from contact with the respiratory tract mucosa called?

After initially conducting a pre- and post-bronchodilator assessment on a stable asthmatic patient admitted to the hospital, how often would you recommend reassessment of peak expiratory flow rate/forced expiratory volume in 1 second?

A patient with chronic bronchitis is receiving heated water aerosol treatments through a jet nebulizer four times daily to aid in mobilizing retained secretions. After each treatment, you note a dramatic increase in the magnitude of coarse crackles heard on auscultation. Which of the following recommendations would you make to the physician?

Which of the following make small-volume ultrasonic drug delivery systems different from their large-volume counterparts? I. They do not use a couplant compartment. II. Drugs are placed directly on the transducer. III. Battery power is available on some units. IV. Patient flow, not a blower, carries the aerosol.

Each firing of a typical metered-dose inhaler delivers about what output volume?

What is the primary hazard of aerosol drug therapy?

Which of the following describes the mass of drug leaving the mouthpiece of a nebulizer as aerosol?

Where do most aerosol particles that are less than 3 $\mu$ m deposit?

A physician wants to deliver a therapeutic aerosol to the upper airway (nose, larynx, trachea). To help ensure maximum deposition in this area, you would select an aerosol generator with an MMAD in what range?

To provide an extra margin of safety during continuous bronchodilator therapy (CBT), which of the following would you recommend be monitored? I.eosinophil count II.serum potassium levels III.electrocardiogram

Which of the following would be correct instructions for a patient being taught proper use of a dry power inhaler? I. Place mouthpiece 4 cm from mouth. II. Exhale slowly to FRC. III. Inhale slowly (less than 30 L/min). IV. Repeat until dose is used up.

To minimize a patient's infection risk between drug treatments with a small-volume jet nebulizer (SVN), what would you do?

A physician wants to deliver a therapeutic aerosol to the lung parenchyma (alveolar region). To help ensure maximum deposition in this area, you would select an aerosol generator with an MMAD in what range?

An asthmatic patient in severe distress with wheezing and dyspnea is admitted to the emergency department and started on albuterol via small-volume jet nebulizer. Which of the following approaches would you recommend to assess this therapy for this patient? I. Perform arterial blood gas analysis. II. Continuously monitor the SpO2. III. Assess breath sounds and vital signs before and after each treatment. IV. Measure peak expiratory flow rate or forced expiratory volume in 1 second before and after each treatment.

Appropriate documentation when conducting point-of-care assessment of a patient's response to bronchodilator therapy includes all of the following except:

When fired inside the mouth, what percentage of the drug dose delivered by a simple metered-dose inhaler (MDI) deposits in the oropharynx?

For which of the following patients would you recommend against using a flow-triggered metered-dose inhaler (MDI) as the sole bronchodilator delivery system?

Which of the following devices would you select to deliver an aerosolized bronchodilator to a young child?

Which of the following methods can be used to minimize the harmful effects of environmental exposure to ribavirin or pentamidine aerosols? i.Use an isolation booth or tent with HEPA filtered exhaust.II.Have health care personnel wear a HEPA filtered mask.III.Use a negative pressure room with adequate air exchange.
