UNIVERSITY OF ALABAMA FINAL PAPER
2026 FULL QUESTIONS WITH CORRECT
ANSWERS GRADED A+
⩥ Arguments for full prescriptive authority. Answer: - APRNs are
educated to practice and prescribe independently without supervision
- National examinations validate ability to provide safe competent care
- Licensure ensures compliance with standards to promote public health
and safety - Limited prescriptive authority creates numerous barriers to
quality, affordable, & accessible patient care
⩥ Drug selection factors. Answer: cost, guidelines, availability,
interactions, side effects, allergies, liver & renal function, need for
monitoring, special populations
⩥ Elements needed to complete a prescription. Answer: - Prescriber
name, license number, and contact information
- Prescriber DEA number, if applicable
- Patient name and date of birth
- Patient allergies
,- Name of medication
- Indication of medication
- Medication strength (e.g., 25 mg, 500 mg/mL)
- Dose of medication and frequency (e.g., 12.5 mg once daily)
- Number of tablets/capsules to dispense
- Number of refills
⩥ Pharmokinetics. Answer: the study of drugs within the body,
absorption , distribution, metabolism, excretion
⩥ 3 ways drugs cross cell membrane. Answer: 1. channels & pores
2. transport systems (p glycoprotein)
3. direct penetration of membrane ( most common -> drugs too large to
pass through pores & channels)
⩥ absorption. Answer: the movement of a drug from its site of
administration into the blood
rate of absorption determines how soon effects will begin
amount of absorption determine intensity of effects
, ⩥ factors affecting absorption. Answer: rate of dissolution, surface area,
blood flow, lipid solubility, pH partitioning
⩥ P-glycoprotein. Answer: Transmembrane protein that transports a
wide variety of drugs out of cells
⩥ How does the liver aid in pharmacokinetics?. Answer: transports
drugs into bile for elimination
⩥ How do the kidneys aid in pharmacokinetics?. Answer: pumps drugs
into urine for excretion
⩥ How does the placenta aid in pharmacokinetics?. Answer: transports
drugs back into the maternal blood
⩥ How does the brain aid in pharmacokinetics?. Answer: pumps drugs
into blood to limit drugs' access to the brain
⩥ passive diffusion. Answer: molecules move from one side of a barrier
to another without expending energy; moving from an area of higher
concentration to lower concentration
⩥ "like dissolves like" rule. Answer: Cell membranes are composed
primarily of lipids; therefore, to directly penetrate membranes, a drug
must be lipid soluble (lipophilic)
