| Question | Answer |
|---|---|
| When two drugs act on a target organ by different mechanisms of action, and the effect of the drug pair is equal to the sum of the separate effects of the drugs is called? | additivity |

| The study of absorption, distribution, metabolism and excretion of a drug is called? | pharmacokinetics |
| The response increases with increasing dosage until additional dosage causes no further effect is called? | ceiling effect |
| When a chemical is added to a drug that has no effect but increases the potency of the original drug 1+0=3, is called? | potentiation |
| A pediatric pt in the ED has a harsh, barking cough, inspiratory strider, tachypnea and tachycardia; No wheezing is noted. What drug would you recommend? Fluticasone, albuterol, Intal, Vaponephrine | Vaponephrine aka racemic epi, for treatment of croup |

| Which of the following drugs has an anti-inflammatory effect? fluticasone, albuterol, Intal, Vaponephrine | fluticasone aka Flovent |
| The advantages of administering steroids by aerosol include | rapid absorption at site of action with reduced systemic side effects |
| The advantage of delivering steroids with B2 agonists is | they potentiate bronchodilating effects |
| Your 5 year old has been diagnosed with RAD. What anti-asthmatic drug would you recommend? hint it's Carol’s favorite | Singulair |
| Chronic airway inflammation associated with asthma would best be controlled by inhaled | Fluticasone |
| Salmeterol is a long acting B-agonist effective in the treatment of? | chronic asthmatic symptoms |
| Which of would not be classified as an anti-asthmatic drug? Intal, Tilade, Albuterol, Accolate | Accolate |
| What drug is the only inhaled steroid available for nebulization? (this buds for you Chris) | Budesonide |
| Fulminant | rapidly occurring |
| Surface tension | is a cohesive force that creates tension at the surface of a liquid |
| The rescue protocol for surfactant replacement drugs is used for | infants who develop IRDS |
| Surfactant replacement drugs are given via | direct instillation |
| Contra-indications for the administration of surfactant replacement drugs are | there are no known contra-indications |
| Without adequate surfactant in the alveoli, how much negative pressure must be generated for alveolar inflation? | -40 to -60 |
| ethyl alcohol is a surface active agent that is useful in the management of | alveolar pulmonary edema |
| Ethyl alcohol may be used as aerosol in the following dose | 5-15 mL of 30-50% solution |
| Clinical symptoms of alveolar pulmonary edema are | pink frothy secretions with bilateral rales on auscultation |
| Surfactant production is normally stimulated by | coughing, periodic sighs, and stimulation of stretch receptors |
| Which of the following is not a bland aerosol? ½ NS, sterile water, sodium bicarbonate, NS | sodium bicarb |
| Which of the following agents is/are hypertonic? | .9% saline, 5% saline, 10% saline |
| Which of the following are hygroscopic? .45% saline, sterile water, NS, 5% saline | 5% saline |
| Mechanism of action for Mucomyst is | breaks the disulphide bonds |
| Mechanism of action for Pulmozyme is | lysis DNA in mucus |
| Na Bicarbonate mechanism of action is | alter the pH, breaking side chains of amino acid in mucus |
| The solution of choice in LVN is | sterile distilled water |
| What solution would you use for sputum induction? | 5% saline |
| The most effective method of mucolysis is? | aerosolized mucolytics |
| The most effective method for mobilizing and improving mucokinetics is | adequate hydration and fluid intake |
| Which of the following is the most effective mucolytic for patients with purulent retained secretions? Mucomyst, dornase alpha, sodium bicarb, hypertonic saline | dornase alfa aka Pulmozyme |
| How many mgs are there in 8 cc of a .5% solution of morphine? | 40mg calc 8 * .5 * 10 = 40 |
| Morphine comes in 10mg/5ml vials. How much do you need to deliver 4 mgs? | 2 vials calc, 10/5 = 4/x so cross multiply and get 10x/10 = 20/10 so x=2, and since we are solving for vials the answer is 2 vials |
| A bottle of Demerol has 50mg/5cc. How much of the bottle do you need to deliver 25 mg of Demerol? | 2.5 ml calc 50/5 = 25/x, cross multiply and 50x = 125, solve for x, 50x/50 = 125/50, x = 2.5 ml |

| If there are 30 mg in 2 cc of a drug, what percentage solution is this? | 1.5%, calc 30 = 2*x*10, 30=20x, solve for x, 20x/20 =30/20, x = 1.5% |
| Approximately what percentage of medication is actually deposited in the lung during an SVN treatment? | 10-20% |
| Drugs are instilled into the airway for the following reasons | stimulate a cough and aid in secretion removal, utilize the mucosa of the lung for drug absorption during a code arrest |
| If an MDI canister floats on its side in a bowl of water it is approximately how full? | empty |
