B. potency
C. purity
D. safety/toxicity



A drug company is conducting a "Phase III" study on a new drug. Which activity will be occuring?

A. The drug will be tested on a third species of animal.
B. The drug will be tested on a second species of animal.
C. The drug will be tested on patients who might benefit from it.
D. The drug will be tested on a small group of human volunteers.




Which of the following affects drug absorption from the site of administration?

A. binding to plasma proteins.
B. liver function
C. solubility.
D. receptor specificity



Drug K can be administered by mouth or parenterally (by injection in vein or tissue). However, the drug dose needed to produce therapeutic blood levels is three times higher when the drug is administered by mouth. Which of the following provides the best explanation for this phenomenon?

A. first-pass liver metabolism of oral dose
B. hepatic enzyme induction resulting from oral route
C. differences in drug solubility between the oral and parenteral routes
D. differences in plasma protein binding between the oral and parenteral routes




Not all drugs in use today have been rated for safety in pregnancy. Of those that have been rated, which classification represents the greatest risk?

A. Schedule II
B. Schedule III
C. Category A
D. Category X




Drug X is an acidic drug that is largely un-ionized in acidic environments. Alkalinizing the urine would __________urinary elimination of this drug.

A. increase
B. decrease
C. have no effect on




Recently the FDA has reccommended the use of Tall man lettering, such as DOPamine rather than dopamine. The purpose of this is to

1. differentiate between trade name and generic name.
2. reduce drug name confusion that could cause errors.
3. designate that this is an OTC medication.




A drug that occupies a receptor but does not activate the receptor is an:

A. adjuvant.
B. affinitant.
C. agonist.
D. antagonist.




Select the true statement about drug allergies:

A. The bigger the first dose of the drug, the more likely you will see an allergic reaction.
B. Symptoms range from mild rash and swelling to airway constriction and shock.
C. It is the same as an idiosyncratic reaction.
D. All of the above.



The 100,000 lives campaign suggested that nationwide implementation of 6 interventions could save 100,000 lives each year. Which is one of these interventions?

A. Patients should be advised to not bring a list of their home medicine when they are admitted to a hospital.
B. When a patient is on a mechanical ventilator, medicine to prevent peptic ulcers should be avoided.
C. We should give a beta-blocker drug early on and at discharge for patients with heart attacks.
D. Aspirin and other platelet inhibitors should never be given in chest pain until you are sure the patient did not have a heart attack.

General Feedback: The 100,000 lives campaign called for research based interventions (among other things) to deploy rapid response teams, give aspirin right away for heart attack, clean skin with chlorhexidine before starting central intravenous lines, keep glucose normal after surgery, reconciliate medications, and prevent pneumonia for patients on ventilators.

A. The drug will be chemically tested in test tubes.
B. The drug will be tested in non-human animals.
C. The drug will be tested in a small number of healthy volunteers.
D. The drug will be tested in a small number of patients who might benefit from the drug.

D. The Center for Drug Control



What activity takes place during "medication reconciliation"?

A. Before approving a drug name, comparisons are made with other drug names to be sure nothing is similar.
B. Double checks are made on labeling of the drug before it is released to patients or those who will administer them.
C. Before administering the drug, double checks are made that it is the right drug, dose, time, route, and patient.
D. A list of the patient home medications is compared to what has been ordered in the hospital.

S. Henry has been taking digoxin for many years. Knowing that digoxin is highly plasma protein bound, what do you predict will occur if you give him a second drug that also binds plasma proteins?

A. the potential for digoxin toxicity will increase
B. the potential for digoxin toxicity will decrease
C. the potential for toxicity of the second drug will decrease
D. nothing should happen



Binding to plasma proteins can affect

A. drug distribution.
B. drug metabolism.
C. drug elimination.
