Pharma Chapter 3 and 4 Review Quiz

Pharmacokinetics focuses on

• what the body does to the drug.

• what the drug does to the body.

• what food does to the drug.

• how effective a drug is in treating a disease.

Absorption is

• the 3rd step in drug transport.

• the last step in drug transport.

• the first step in drug transport.

• the inactive step in drug transport.

Distribution refers to

• how drugs are broken down within the body.

• how drugs are transported throughout the body.

• how drugs absorbed into the liver.

• how drugs are dissolved in the blood.

Metabolism is a process whereby drugs are

• made less harmful to the body.

• made very active in the body.

• made less or more active in the body.

• reduced to liquid in the body.

Excretion process remove

• blood from the body.

• food from the body.

• Oxygen from the body.

• drugs from the body.

The rate of elimination and half-life (t1/2) are important to the healthcare provider because

• t1/2 of a drug is a related measurement used to ensure that maximum therapeutic dosages are administered.

• therapeutic range of the drug depends on the food a patient eats.

The peak plasma level of a drug occurs

• when the medication has reached its lowest concentration.

• when the medication has reached its highest concentration.

• when the medication is in a gas form.

• When the drug can no longer be absorbed.

The onset of drug action represents

• the amount of time it takes to produce therapeutic effect after drug administration.

• the amount of time it takes to produce a side effect after drug administration.

• the amount of time it takes to dissolve a drug after administration.

• the amount of time it takes to excrete a drug.

A nurse enters a patient's room with medication along with a stethoscope, a fairly large -looking syringe, and a container of water. In the course of administering the medication, the nurse will use all of these items. Which of the following routes will the nurse likely use?

• Transdermal

• Intravenous (parenteral)

• Nasogastric (enteral)

• Rectal

Answer explanation

The stethoscope , large syringe, and water are all needed to administer medication by way of the nasogastric route.

The nurse will not crush the extended- release medications ordered for the patient because:

• They are very distasteful, and this reduces patient compliance.

• Crushing alters the rate of absorption and medication delivery.

• Multiple drug pieces cause obstructive symptoms.

• Crushed oral medications have reduced bioavailability.
