Q

to ensure the protection of healthcare clinicians when giving these drugs, they must use

A

nebulizer using a negative pressure room or booth and ensure personnel barrier protection

24
Q

Respiragard II nebulizer is what kind of nebulizer system

A

a nebulizer system with a one way valve and expiratory filters to reduce environmental contaminiation

25
Indications of ribavirin (virazole)
- patients hospitalized with RSV (Respiratory syncytial virus) - lower respiratory tract infection - complicated congenital heart disease - bronchopulmonary dysplasia, CF, other chronic lung condition - premature infants - immunodeficiency/ recent transplant or chemotherapy
26
mode of action for ribavirin (virazole)
- not completely understood - used to stop viral RNA synthesis and viral mRNA capping - prevents construction and shedding of viable viral particles
27
dosage and administration of ribavirin (virazole)
dosage: 20mg/mL of 2% solution administration: SPAG (tent, hood, mechanical ventilator)
28
side effects of ribavirin (virazole)
- deterioration of pulmonary function - skin irritation/ rash - eyelid erythema/conjunctivitis with aerosol administration - equipment malfunctions from drug precipitate
29
environmental contamination with aerosolized ribavirin (virazole)
- potential for mutagenic and carcinogenic effects - teratogenic and embrocidal (pregnant patients and practitioners should not be exposed) - exposure to ribavirin in health care workers
30
indication for inhaled tobramycin (TOBI)
intended to manage chronic infection with P. aeruginsoa in patients with CF
31
side effects of inhaled tobramycin (TOBI)
voice alteration and tinnitus - side effects increase if patient is on other antibiotics taken via IV
32
mode of action for tobramycin (TOBI)
- bactericidal against gram NEGATIVE organisms - blocks protein synthesis in the bacteria and causes cellular death
33
administration of inhaled TOBI
- SMV - cannot be mixed with other solutions - should be inhaled after other treatment - healthcare worker exposure should be minimized - pretreat with bronchodilator - drug incompatibility
34
what drug do you need to refrigerate
tobramycin
35
side effects of systemic TOBI
- ototoxicity - hypomagnesemia - loss of hearing - allergic reactions - vertigo - fetal harm - nausea - deafness - nephrotoxicity - neruomuscular blockade - worsening of neuromuscular disorder
36
mode of action for inhaled aztreonam (cayston)
synthetic bactercidal antibiotic
37
what does inhaled aztreonam treat
treats pulmonary symptoms in patients with CF dealing with P.aeruginosa infections
38
what type of system is used for inhaled aztreonam
aerosolized using the alteration nebulizer system
39
adverse effects for inhaled aztreonam (cayston)
- bronchospasm - decreased FEVI
40
indications for inhaled zanamivir (relenza) (DPI)
treatment of uncomplicated influenza illness in adults, during the early onset of infection
41
mode of action for zanamivir (relenza)
- neuraminidase inhibitor - binds with and blocks the enzymes action - inhibits virus particle seperation - prevents virus release from infected cells
42
adverse effects of zanamivir (relenza)
- bronchospasm - deterioration of lung function - under treament of bacterial infection - not effective against bacterial infection that may exhibit flu-like symptoms - look for reactions such as diarrhea, nausea, vomiting, cough, dizziness, and headaches
43
indications for inhaled pulmonary vasodilators
- pulmonary hypertension caused by: COPD, and corpulmonale, acute hypoxemia seen in ARDS or shock, premature babies
44
Nitric Oxide indications
- treatment of neonates with persistent pulmonary hypertension (PPH) - relaxes vascular smooth muscle in pulmonary vasculature - when inhaled, produces pulmonary vasodilation, reducing pulmonary artery pressure and improving V/Q mismatching
45
adverse/ side effects of nitric oxide
- hypotension is most common side effect - rebound pulmonary hypertension and hypoxemia - toxic NO2; nitrous and nitric acid; you can prevent this by decrease contact time and concentration of gas - methemoglobinemia
46
dosage for nitric oxide
to increase PaO2 = 1-2 ppm to decrease pulmonary artery pressures = 10-40 ppm
47
indications for iloprost (ventavis)
used in treatment of pulmonary hypertension
48
how is Iloprost administered
with I-neb nebulizer
49
mode of action for iloprost (ventavis)
acts by dilating pulmonary vasculature and affect platelet aggregation
50
Side effects of iloprost (ventavis)
- headaches - increased cough other side effects secondary to the vasodilatory properties of iloprost - syncope - pulmonary edema
51
mode of action for treprostinil (tyvaso)
prostacyclin analogue that causes vasodilation of pulmonary and systemic arterial vascular beds and inhibits platelet aggregation
52
indications for treprostinil (tyvaso)
indicated for treatment of pulmonary arterial hypertension to increase walking distance in patients with New York heart association calls III symptoms
53
administration of Treprostinil (tyvaso)
Tyvaso inhalation system
54
what is neublized flonlan used for
- used in the treatment of pulmonary hypertension to provide selective pulmonary vasodilation and improve arterial oxygenation - temporary management of adult patients with ARDS or mild to moderate pulmonary hypertension that is unresponsive to conventional therapy
55
contradictions of flolan (epoprostenol)
do not use flown with patients who have congestive heart failure (CHF) with severe left ventricular failure
56
Application of Flolan
- via mechanical ventilator - infusion pump - mini heart low flow nebulizer - IV extension set
57
Which drug should not be discontinued abruptly to avoid potential increase in PAP and/or worsening of oxygenation
Flolan (epoprostenol)
