Assignment 2: Volatile Drug

Week 2 Assignment 2 Quiz 1. Question :A patient’s nutritional intake and lab work reflect hypoalbuminemia. This is critical to prescribing because: Distribution of drugs to target tissue may be affected The solubility of the drug will not match the site of absorption There will be less free drug available to generate an effect Drugs bound to albumin are readily excreted by the kidney Question 2. Drugs that have a significant first-pass effect: Must be given by the enteral (oral) route only Bypass the hepatic circulation Are rapidly metabolized by the liver and may have little if any desired action Are converted by the liver to more active and fat-soluble forms Question 3. An advantage of prescribing a sublingual medication is that the medication is: Absorbed rapidly Excreted rapidly Metabolized minimally Distributed equally Question 4. Which one of the following statements about bioavailability is true? Bioavailability issues are especially important for drugs with narrow therapeutic ranges or sustained release mechanisms. All brands of a drug have the same bioavailability. Drugs that are administered more than once a day have greater bioavailability than drugs given once daily. Combining an active drug with an inert substance does not affect bioavailability. Question 5. The route of excretion of a volatile drug will likely be: The kidneys The lungs The bile and feces The skin

Volatile solvents are liquids that vaporize at room temperature.

These organic solvents can be inhaled for psychoactive effects and are present in many domestic and industrial products such as glue, aerosol, paints, industrial solvents, lacquer thinners, gasoline, and cleaning fluids.

Some substances are directly toxic to the liver, kidney, or heart, and some produce peripheral neuropathy (nerve damage usually affecting the feet and legs) or progressive brain degeneration.

The most frequent users of these substances are young adolescents and street children. The user typically soaks a rag with inhalant and places it over the mouth and nose, or puts the inhalant in a paper or plastic bag which is then put over the face.

Signs of intoxication include agressiveness, lethargy, impaired movement, euphoria, impaired judgement, dizziness, rapid involuntary movement of the eyes, blurred vision or double vision (diplopia), slurred speech, tremors, unsteady gait, overactive reflexes, muscle weakness, stupor, or coma.
