Q

Injectable drug forms

P. 45-49

A

Forms of drugs manufactured to be given via injection such as intravenous (IV) or intramuscular (IM).

Q

Rectal drug forms

P. 45; 593

A

Drugs manufactured to be administered via the rectal route, such as suppositories.

  • suppository
  • enema
17
Q

Route of delivery

P. 42; 593

A

The way that drugs are taken into the body.

  • intramuscular
  • intravenous
  • topical
  • oral
  • rectal
  • subcutaneous
18
Q

Solution

P. 45

A

Liquid drug form in which the drug is totally and evenly dissolved.

• Appearance is clear rather than cloudy or settled (as with a suspension).

19
Q

Suppository

P. 45

A

Drug suspended in a substance, such as cocoa butter, that melts at body temperature.

Used:
• rectal
• vagial
• urethral

20
Q

Suspension

P. 44

A

Liquid form of medication that must be shaken well before administration because the drug particles settle at the bottom of the bottle. The drug is not evenly dissolved in the liquid until properly shaking the mixture.

21
Q

Sustained-release capsule or tablet

P. 44

A

Capsule or tablet containing drug particles that have various coatings (often of different colors) that differ in the amount of time required before the coatings dissolve. This form of drug preparation is designed to deliver a dose of drug over an extended period of time.

21
Q

Sustained-release capsule or tablet

P. 44

A

Capsule or tablet containing drug particles that have various coatings (often of different colors) that differ in the amount of time required before the coatings dissolve. This form of drug preparation is designed to deliver a dose of drug over an extended period of time.

22
Q

Syrup

P. 45; 594

A

A concentrated solution of sugar in water to which specific medicinal substances are usually added.

• Sweetened, flavored liquid drug form. Cherry syrup drug preparations are common for children

23
Q

Tablet

P. 44

A

Disk of compressed drug.

24
Q

Topical drug forms

P. 49

A

Drugs for dermal application and drugs for mucosal application.

-Those for dermal application include the following:

  • cream or ointment
  • lotion
  • liniment
  • transdermal patch
Those for mucosal application include the following: 
• eye, ear, and nose drops
• eye ointment
• vaginal creams
• rectal and vaginal suppositories
• douche solution
• Buccal tablet
• sublingual tablet
• sandwiching the drug between very thin plastic membranes and then placing it under the patient's eyelid.
25
Q

Intramuscular injection

P. 46

A

Injected into the muscle by positioning the needle and syringe at a 90 degree angle from the skin.

•Absorption is fairly rapid due to the vascularity (presence of many blood vessels) in the muscle

26
Q

Subcutaneous injection

P. 46

A

Injected into the fatty layer of tissue below the skin by positioning the needle and syringe at a 45 degree angle from the skin.

• this may be the route of choice for drugs that should not be absorbed as rapidly as through the IV or IM routes.

27
Q

Intradermal injections

P. 46

A

Injected just beneath the skin by positioning the needle bevel up and the syringe at a 15 degree angle from the skin.

  • This route is used primarily for allergy skin testing.
  • because of the lack of vascularity in the dermis, absorption is slow.
28
Q

Intravenous injections

P. 46

A

Injected directly into a vein. Immediate absorption and availability to major organs renders this route a dangerous one.

• IV drugs are usually administered by physicians, paramedics, or registered nurses.

  • Types of IV Injections:
    * IV Push
    * IV Infusion
    * IV piggyback (IVPB)
29
Q

Epidural injection

P. 48

A

Injected into a catheter that has been placed by an anesthesiologist in the epidural space of the spinal canal.

• Medications for pain can be administered into the catheter by bolus a (measured amount of solution) in a syringe or by continuous infusion through the tubing attached to a bag of solution.

30
Q

Less common parenteral routes

P. 48-49

A
  • Intraosseous - injected directly into the marrow of the long bones. This route may be used to administer medications during a cardiac arrest or other emergency situations when traditional IV access is not available.
  • intraventricular - drug injected directly into the brain via a catheter (called a ventriculostomy) to be placed in a brain ventricle. In critical care, antibiotics can be given via ventriculostomy tube.
  • intraspinal - injected into the subarachnoid space, which contains cerebrospinal fluid that surrounds the spinal cord. Drugs injected by this route are frequently anesthetics, which render a lack of sensation to those regions of the body distal to the intraspinal injection.
  • intracapsular (intra-articular) - injected into the capsule of a joint, usually to reduce inflammation, as in bursitis. Arthritic or bursitic joints often injected with anti-inflammatory drugs include shoulders, elbows, wrists, ankles, knees, and hips.
31
Q

Various supplies used for administering all different drug forms

(P. 52-56)

A
  • medicine cup
  • individual pill crusher and pill cutter
  • ampule
  • vial
  • needles
  • syringes
  • oral syringes
32
Q

Occupational Safety and Health Administration (OSHA)

P. 56

A

Have mandated that every effort be made to reduce the risk of needle-stick injuries that could lead to exposure to blood-borne pathogens, such as the human Immunodeficiency virus (HIV), Hepatitis B virus (HBV) or hepatitis C virus (HCV).
