PAPER 2025/2026 ELITE REVIEW WITH
QUESTIONS AND CORRECT VERIFIED
SOLUTIONS 100% PASS
◍ What is a Black Box Warning: Answer: is considered a
contraindication to administer that drug.
◍ What is the drugs half-life? Answer: Half-life specifically means the
amount of time it takes for an administered drug to be halfway cleared
from the system.
◍ Peak of action: Answer: the time between drug administration and
maximum concentration of drug in the blood stream. Best therapeutic
effect.
◍ Duration of action: Answer: the time between onset of action and
metabolism of drug below the minimum needed for an effect. The length
of time you have the drug in your system.
◍ According to the WHO what is the first step in the prescribing
process? Answer: The first step is to define the patient's problem
,◍ The second step of the prescribing process is to Answer: specify the
therapeutic objective
◍ The third step of the prescribing process is to Answer: choose which
drug or treatment is needed.
◍ The fourth step of the prescribing process is to Answer: Start the
treatment
◍ The fifth step of the prescribing process is to Answer: Educate the
patient
◍ The sixth step of the prescribing process is to Answer: Monitor the
treatment
◍ Explain first pass metabolism Answer: much of the drug is lost in the
absorption process. The liver metabolizes many drugs, thus reduces the
bioavailabilty of the drug.
◍ What is the fasted route of absorption: Answer: The fastest route of
absorption is inhalation, and not as mistakenly considered the IV
administration.
, ◍ Why does the GI tract take longer to absorb? Answer: The GI tract is
lined with epithelial cells; drugs must permeate through these cells in
order to be absorbed into the circulatory system.
◍ What is One particular cellular barrier that may prevent absorption of
a given drug? Answer: the cell membrane. Cell membranes are
essentially lipid bilayers which form a semipermeable membrane. Pure
lipid bilayers are generally permeable only to small and uncharged
solutes, hence whether or not a molecule is ionized will affect its
absorption, since ionic molecules are charged.
◍ Why does absorption occur at a slower rate for oral, IM, SQ routes?
Answer: Absorption occurs at a slower rate because the complex
membrane systems of GI mucosal layers, muscle, and skin delay drug
passage.
◍ The ability of a drug to cross a cell membrane depends on: Answer:
whether the drug is water or lipid (fat) soluble. Lipid-soluble drugs
easily cross through cell membranes; water-soluble drugs can't. Lipid-
soluble drugs can also cross the blood-brain barrier and enter the brain.
◍ As a drug travels through the body, it comes in contact with? Answer:
proteins such as the plasma protein albumin. The drug can remain free or
bind to the protein. The portion of a drug that's bound to a protein is
inactive and can't exert a therapeutic effect. Only the free, or unbound,
portion remains active. A drug is said to be highly protein-bound if more
than 80% of the drug is bound to protein.
