Show The best sequence of administration is (C, D, A and B). Status asthmaticus is potentially a life-threatening respiratory event, so albuterol (C), a beta2 adrenergic agonist and bronchodilator, should be administered by inhalation first to provide rapid and deep topical penetration to relieve bronchospasms, dilate the bronchioles, and increase oxygenation. In stepwise management of persistent asthma, a long-action bronchodilator, such as salmeterol (Serevent Diskus) (D) with a 12-hour duration of action should be given next. Prednisone (A), an oral corticosteroid, provides prolonged anti-inflammatory effects and should be given after the client's respiratory distress begins to resolves. Gentamicin (B), an antibiotic, is given deep IM, which can be painful, and may require repositioning the client, so should be last in the sequence. Which route of administration bypasses firstTwo ways to bypass first pass metabolism involve giving the drug by sublingual and buccal routes. The drugs are absorbed by the oral mucosa in both methods. In sublingual administration the drug is put under the tongue where it dissolves in salivary secretions.
Which routes of administration can be used to avoid the first pass effect?Alternative routes of administration, such as insufflation, suppository, intravenous, intramuscular, inhalational aerosol, transdermal, or sublingual, avoid the first-pass effect because they allow drugs to be absorbed directly into the systemic circulation.
What is the first pass effect quizlet?The first pass effect is the metabolism of the drugs by the liver, having been absorbed through the intestine. It determines the concentration of drug (active metabolite that will act on the target site.)
What method of medication administration should have its 1st peak concentration in the blood in about 1 hour?The time to take peak levels depends on the route of administration. The peak level is taken about 15 to 30 minutes after intravenous injections or infusions, 30 minutes to 1 hour after intramuscular injections, and about 1 hour after a drug is taken orally.
