PRACTICE EXAMINATION 2026
QUESTIONS WITH ANSWERS GRADED A+
◍ Fosfomycin (Monurol).
Answer: A cell wall synthesis inhibitor used for uncomplicated UTIs in
women.
◍ What does potency refer to in pharmacology?.
Answer: The amount of drug needed to produce a specific effect, often
measured as ED50.
◍ What is the difference between a competitive and a noncompetitive
antagonist?.
Answer: A competitive antagonist competes with the agonist for the same
receptor site, while a noncompetitive antagonist binds irreversibly to the
receptor.
◍ Bacterial Resistance.
Answer: The ability of bacteria to evade the effect of an antibiotic.
◍ What are the key steps in the prescribing process?.
Answer: Patient assessment, diagnosis & treatment plan, medication
selection, and prescription & patient education.
◍ What is the purpose of Phase II Metabolism?.
Answer: Phase II Metabolism consists of conjugation reactions that add an
endogenous substance to the drug molecule, making the metabolite more
water-soluble and almost always inactivating the drug.
◍ Bacterial Resistance Mechanisms.
Answer: Enzymatic Inactivation, Target Site Modification, Efflux Pumps,
, Decreased Permeability.
◍ Metformin Side Effects.
Answer: Gastrointestinal distress (diarrhea, nausea, bloating), lactic acidosis,
vitamin B12 deficiency.
◍ What are the essential components of a prescription?.
Answer: Essential components include patient identifiers, date of issue,
medication details (name, strength, dosage form), directions for use,
quantity to dispense, refills, and prescriber information.
◍ Griseofulvin.
Answer: Targets new keratin and is used for systemic treatment of Tinea.
◍ Risk of Heart Failure Hospitalization.
Answer: Seen with Saxagliptin and Alogliptin.
◍ Type 2 DM Insulin Management.
Answer: Insulin is typically initiated when oral agents fail or A1c is very
high; starting with basal insulin only at a low dose, titrated based on fasting
blood glucose.
◍ What is the definition of efficacy in pharmacology?.
Answer: The maximal effect a drug can produce, represented as the height
of the dose-response curve.
◍ Agents to Avoid in Pregnancy.
Answer: Tetracyclines, Fluoroquinolones, TMP/SMX, and Metronidazole.
◍ Common Etiologies of Hypoglycemia.
Answer: Insulin overdose/mistiming, Sulfonylureas, alcohol abuse, missed
meals, increased exercise.
◍ What is Half-Life (t½) in pharmacology?.
Answer: Half-Life (t½) is the time it takes for the plasma concentration of a
drug to decrease by 50%.
◍ What does pharmacokinetics (PK) study?.
Answer: What the body does to the drug, summarized by the acronym
, ADME.
◍ Narrow Spectrum Antibiotics.
Answer: Target a limited range of bacteria, preferred for definitive therapy.
◍ What is an antagonist?.
Answer: A drug that binds to a receptor to block an agonist from producing
a response.
◍ What is the significance of protein binding in drug distribution?.
Answer: Only unbound (free) drugs are pharmacologically active; low
albumin levels can increase toxicity risk.
◍ What is the Nurse Practitioner's role in prescribing?.
Answer: Grounded in safety, evidence-based practice, and patient-centered
care.
◍ What is the therapeutic index (TI)?.
Answer: The ratio of the dose that is toxic to the dose that is therapeutically
effective, indicating a drug's safety.
◍ Acne Treatment.
Answer: Clindamycin (often topical), Tetracyclines.
◍ NPH to Glargine Conversion.
Answer: When converting from a twice-daily NPH regimen to a once-daily
Glargine regimen, the new Glargine dose is typically 80% of the total daily
NPH dose.
◍ How does drug absorption differ in pediatric patients?.
Answer: In pediatric patients, gastric pH is higher at birth and gradually
acidifies, affecting drug absorption.
◍ What genetic factors influence Warfarin dosing?.
Answer: SNPs in the CYP2C9 gene affect Warfarin metabolism, while
SNPs in the VKORC1 gene alter sensitivity to the drug, necessitating
genetic testing for optimal dosing.
◍ Hypoglycemia.
