Ati Pharmacology 2026: Comprehensive
Topic Test Questions And Answers With
Rationales/Graded A+/2026 Update/100%
Correct
Part 1: Basic Pharmacology Principles (Questions 1–10)
1. A nurse is teaching a patient about the enteral route of administration.
Which of the following is an example of this route?
A. Intravenous injection
B. Subcutaneous injection
C. Oral tablets
D. Intramuscular injection
Rationale: Enteral administration involves the gastrointestinal tract (oral,
sublingual, rectal). Oral tablets are enteral; IV, SubQ, and IM are parenteral.
2. A drug with a high first-pass effect is best administered via which route?
A. Oral
B. Sublingual
C. Rectal
D. Intravenous
Rationale: First-pass effect reduces oral bioavailability. Sublingual bypasses portal
circulation and liver metabolism.
3. Which pharmacokinetic phase describes the movement of a drug from the
bloodstream into tissues?
A. Absorption
B. Distribution
C. Metabolism
D. Excretion
Rationale: Distribution is the transport of drugs by the bloodstream to target
tissues.
4. A patient has a decreased albumin level. The nurse should monitor for
which effect?
,A. Reduced drug absorption
B. Increased free drug levels and toxicity
C. Faster drug metabolism
D. Reduced renal excretion
Rationale: Low albumin = fewer protein-binding sites → more free, active drug
→ risk for toxicity.
5. Cytochrome P-450 enzyme system is primarily involved in:
A. Absorption
B. Distribution
C. Metabolism
D. Excretion
Rationale: CYP450 enzymes in the liver metabolize many drugs, affecting
duration and intensity.
6. A patient is receiving a drug that is a weak acid. The nurse knows it will be
excreted faster if the urine is:
A. Acidic
B. Alkaline
C. Neutral
D. Variable
Rationale: Weak acids are ionized (trapped) in alkaline urine, promoting
excretion. Opposite for weak bases.
7. The half-life of a drug is 4 hours. How long will it take to reach steady
state?
A. 8 hours
B. 12 hours
C. 20 hours
D. 40 hours
Rationale: Steady state occurs after 4–5 half-lives (4×5=20 hours).
8. A nurse is reviewing a medication order. Which part of the order is most
critical to prevent medication errors?
A. Patient’s room number
B. Drug name, dose, route, time, and patient identifier
, C. Prescriber’s name
D. Date of order
Rationale: The “Rights of Medication Administration” require at least drug, dose,
route, time, patient ID.
9. A patient develops hives and wheezing after a new antibiotic. This is an
example of:
A. Side effect
B. Idiosyncratic reaction
C. Type I hypersensitivity
D. Carcinogenic effect
Rationale: Immediate IgE-mediated reaction (urticaria, bronchospasm) = Type I
hypersensitivity.
10. Which laboratory value indicates therapeutic range for digoxin?
A. 0.5–0.8 ng/mL
B. 0.8–2.0 ng/mL
C. 2.5–4.0 ng/mL
D. >5.0 ng/mL
Rationale: Digoxin therapeutic range is 0.8–2.0 ng/mL. >2 = toxicity risk.
Part 2: Antibiotics & Antifungals (Questions 11–25)
11. A patient on vancomycin reports ringing in the ears. The nurse’s priority
action is to:
A. Reassure the patient it is temporary
B. Hold the next dose and notify the provider
C. Administer aspirin
D. Increase IV fluid rate
Rationale: Tinnitus is early sign of ototoxicity; stop drug and notify provider.
12. Which antibiotic requires a patient to avoid aged cheese, red wine, and
smoked meats?
A. Ciprofloxacin
B. Linezolid
