Question | Answer |
---|---|
What PH is the stomach | 1-2 |
Is everything in a pill the drug | no has active drug,binder, lubricant, Disintegrant, and diluent |
PH | Measures the acidity or the opposite (alkalinity) of a substance |
Disintegration | The breaking apart of a tablet into smaller pieces |
Repeat action tablets | release one dose of the drug and then release a second dose sometime later |
Extended release (ER or XR) | Several oral formulations release the drug so that a longer duration of action is achieved compared to a conventional tablet |
Gels | agents form an interlacing three-demensional network of particles that restricts the movement of the solvent. 12-24 hours to reach max viscosity and clarity |
Solvent | a liquid that can dissolve another substance to form a solution |
is the best known example of a sublingual tablet formulation | Nitroglycerin |
The most common rectal administration dosage forms | Suppositories, solutions and ointments |
Intravenous (IV) | Needle gauge 16-20, Needle Length 1-1.5" Fastest |
Intramuscular (IM) | Needle gauge 19-22, Needle length 1-1.5" 2nd fastest |
Subcutaneous (SC) | Needle gauge 25-27, Needle length 3/8-1" Third fastest |
Intradermal (ID) | Needle gauge 25-26, Needle Length 3/8" 4th fastest |
Thrombus | (blood clot) formation can result from many factors: extremes in solution PH, particulate material or Catheter trauma, |
Phlebitis | Inflammation of the vein, can be caused by extremes in solution PH, particulate material or Catheter trauma, |
Air emboli | Occurs when air is intro-duced into the vein. The human body is generally not harmed by very small amounts of air injected into the venous system, but excess air injected into the veins can be fatal. |
Particulate Material | can include small pieces of class that chip from the product's vial or rubber pieces that come from the closure on the vials |
LVP | Large volume parenteral |
SVP | small volume parenteral |
Aqueous | Water based |
Intramuscular injections | result in lower but longer lasting blood concentration than with intravenous administration, have an absorption step which delays the time to peak concentration |
Depot | area in the muscle where the formulations is injected during an IM injection |
Wheal | Raised blister-like area on the skin caused by an Intradermal injection |
Ophthalmic ointment tubes | Typically small holding approximately 3.5 g of ointment and fitted with narrow gauge tips which permit the extrusion of a narrow ribbon of ointment |
Alveolar sacs (alveoli) | small sacs of specialized tissue that transfer oxygen out of inspired air into the blood and carbon dioxide out of the blood and into the air for exhalation |
The skin is composed of three layers of tissue | Epidermis, dermis, subcutaneous tissue |
Toxic shock syndrome (TSS) | rare and potentially fatal disease that results from a severe bacterial infection of the blood |
which route of administration is not an enteral route | inhalation |
which of the following routes is least likely to give a systemic effect | intradermal |
within the alimentary tract, phs of 5-7 are typically found in the | small intestine |
a dissolution step would not be necessary for drug absorption from a/an | intravenous solution |
modified release tablets might be called | extended release, prolonged action or long acting |
nonaqueous solutions often contain glycerin, alcohol and | propylene glycol |
a gel | is a network of interlacing particles |
the best known example of a drug given by sublingual administration is | nitroglycerin |
which parenteral route of administration would typically use the longest needle with the smallest gauge | intravenous |
which intravenous dosage form requires the technician to consider syringeability and injectability? | suspensions |
which will not be caused by particulate material in an intravenous injection? | air emboli |
which is not used to administer a drug by parenteral route? | syringe, elastomeric pump , infusion pump Answer NONE |
Injections are administered into the top layer of the skin at a slight angle using short needles | Subcutaneous |
a raised blister-like area on the skin caused from an intradermal injection is called a | Wheal |
deltoid | intramuscular administration |
0.1 ml | intradermal administration |
20 second | intravenous administration |
implants | subcutaneous administration |
which ophthalmic formulation will maintain the drug in contact with the eye the longest | ointment |
when administering ophthalmic drops, why is instilling two drops at a time not recommended? | the second drop will be lost due to spillage |
what percent of an administered ophthalmic solution is actually delivered to the eye? | 20% |
when administering a nasal spray | breathe through the nostril while spraying the solution |
a drug is administered by inhalation using a metered dose inhaler (MDI) aerosol. Which pathway will the drug follow | mouth, trachea, bronchioles, alveoli |
which device would be used to administer a volatile drug intransally? | nasal inhaler |
a spacer with a MDI aerosol will | help coordinate actuation and inspiration |
which layer of skin contains the stratum corneum | epidermis |
