Q

Describe pHs effect on drugs

A

Acidic drugs are well absorbed in the stomach. Drugs that are basic remain ionized or insoluble in an acid environment,these drugs are not absorbed before reaching the small intestine

Q

What could cause a drugs unequal distribution?

A

The drug may bind to plasma proteins, which causes unequal distribution and prevents the drug from reaching its intended site of action. Another factor affecting distribution is the blood brain barrier.

(Drugs readily move across the placenta)

Q

Describe excretion of a drug

A

After the drug is broken down to an inactive form, excretion of the drug occurs. Excretion is the process of removing a drug or it’s metabolites from the body. The kidneys excrete most drugs. The lungs are the primary route for the excretion of gases substances, such as inhalation anesthetics. Many drugs are excreted through bile in the gastrointestinal tract. The sweat, salivary and mammory glands are also routes for drug excretion

The track technique, attach a clean needle to the syringe after the syringe is filled with the medication to prevent ejection of any residual medication on the needle and just superficial tissue.

True

60
Q

Describe mix-o-vials, when are they used?

A

Medications that are packaged in Mix-O-Vials have the powder form of the medication in the bottom compartment and the diluent solution in the top portion of the vial. The powder and the liquid are separated by a rubber stopper. Medications that are unstable in solution over long periods of time are packaged in this manner.

61
Q

Syringes are available in several sizes. There are three main types of syringes: the hypodermic syringe, the tuberculin syringe, and the insulin syringe. These syringes vary in volumes of 1 mL, 3 mL, 5 mL, 10 mL, 20 mL, 30 mL, 50 mL, and 60 mL. Each syringe is designed for a specific use, but the parts of all syringes are the same.

Q

Describe insulin syringes

A

Insulin is measured in USP units. Insulin is manufactured in multi-dose vials of 100 units per milliliter. There are three main syringes that are used to measure and administer insulin.

The first syringe is the Lo-Dose syringe. This syringe can be either 50 units in 0.5 mL total volume or 30 units in 0.3 mL total volume. Each calibration on these syringes is 1 unit. When smaller doses of insulin are to be given, the smaller the syringe, the more accurately the dose is measured.

The second syringe designed to administer insulin is the single scale 1 mL syringe. This syringe is calibrated in 2 unit increments. This syringe is ideal for the patient with vision problems.

The third syringe is the 1 mL double scale syringe. The syringe is marked on one side in even calibrations (10, 20, 30, 40, etc.) and odd calibrations on the opposite side (5, 15, 25, 35, etc.). To avoid confusion, use the odd scale for odd doses, i.e., 17 units and the even scale for even doses, i.e., 20 units.
