NURS 615 PHARM EXAM 2
MARYVILLE EXAM WITH CORRECT
QUESTIONS AND ANSWERS 2025
What factors are associated with clinical judgment when prescribing medications? -
CORRECT-ANSWERSPrescribing a drug is based on a thorough assessment of the
patient and the patient's environment. The determination of potential medical and nursing
diagnoses, a review of the potential alternative therapies, specific knowledge about the
drug chosen, and the disease process it is going to treat, known as patient centered care.
The best therapy is usually the least invasive, least expensive, and the least likely to cause
adverse reactions
What are the criteria for choosing an effective drug? - CORRECT-ANSWERSMultiple
drugs may be able to treat a specific condition. You must consult nationally recognized
guidelines for disease management to determine the most effective drug.
How does hypoalbuminemia affect the process of prescribing? - CORRECT-
ANSWERSMany drugs that carry an electric charge are bound to albumin in the blood.
The distribution of the drug to target tissues may be affected if hypoalbuminemia is
present.
What is the drug's half-life? - CORRECT-ANSWERSIn clinical practice it takes about
four to five times the half-life for a drugs concentration to read steady state after a drug is
started, stopped or changed. Hal life is the amount of time for a drug to be half cleared.
What is meant by the onset of action, peak of action, duration of action of medications? -
CORRECT-ANSWERSThe onset of action is the time between the drug administration
and the time that you see the drugs minimum effect. Onset is the first sign of a drugs
, therapeutic effect. Peak of action is the time of the maximum concentration of the drug in
the blood. Duration of action is the onset of action and the metabolism of the drug below
the dose needed for an effect.
Explain first pass metabolism. - CORRECT-ANSWERSThis occurs when the
concentration of the drug is greatly reduced before it reaches the systemic circulation. It
is the portion of the drug lost during absorption. Generally, occurs in the liver or gut wall.
After a drug is swallowed it is absorbed by the digestive system and enters the hepatic
system. It is then carried by the portal vein to the liver before it reaches the rest of the
body. The liver metabolizes many drugs to such an extent that only a small portion of the
drug reaches the rest of the body. bioavailability of the drug thus is greatly reduced by the
liver. Sublingual administration can bypass the first pass system plus it is also faster than
oral route.
What is a steady state? - CORRECT-ANSWERSThe overall intake of a drug is fairly and
dynamic equilibrium with its elimination. Steady state is reached when the time of four to
five times the half-life is reached since the drug had been started.
What factors affect the drug's absorption? - CORRECT-ANSWERSAbsorption involves
several steps. First the drug must be introduced via route of administration and the form
of medication like tablet or capsule. In IV or IM administration the absorption is less
variable and bioavailability is near 100%. IV administration is considered to lose no
portion of the drug. The fastest route of absorption is inhalation. Drugs must pass through
the epithelial cells of the GI tract to be absorbed by the circulatory system. Cell
membranes may affect the absorption of some drugs because they are made of lipid
bilayers that are semi permeable. This means only small uncharged solutes can pass
