NR567 Advanced Pharmacology for the AGACNP Final Exam
10-Line Exam Coverage in Points Form
1. Pharmacokinetics & Pharmacodynamics (Core Science) – Volume of distribution (Vd)
reflects tissue distribution, with lipophilic, highly protein-bound drugs having larger Vd;
hepatic failure reduces metabolism of hepatically cleared drugs, prolonging half-life; and
the first-pass effect describes drug inactivation by liver enzymes after GI absorption .
2. Cardiovascular Pharmacology I – HF & Antiarrhythmics – Digoxin inhibits Na⁺/K⁺-
ATPase, increasing intracellular calcium and contractility; hypokalemia potentiates
digoxin toxicity; amiodarone causes pulmonary fibrosis, thyroid dysfunction, and blue-
gray skin discoloration; adenosine is first-line for acute SVT termination;
sacubitril/valsartan (Entresto) is an ARNI (neprilysin inhibitor + ARB) for HFrEF .
3. Cardiovascular Pharmacology II – Anticoagulation & Antiplatelets – Warfarin blocks
vitamin K-dependent carboxylation of factors II, VII, IX, X (monitored by INR); heparin is
monitored by aPTT (1.5–2.5x control); LMWH and DOACs require renal dosing;
protamine reverses heparin; vitamin K reverses warfarin .
4. Shock & Vasopressors – Norepinephrine is first-line IV vasopressor for septic shock
(alpha-1 mediated vasoconstriction); milrinone (PDE-3 inhibitor) causes positive inotropy
AND vasodilation (may cause hypotension); low-dose corticosteroids may shorten time
to shock reversal in refractory septic shock .
5. Critical Care & Emergency Pharmacology – For hypoglycemic emergency: IV dextrose
50% (if IV access) or glucagon IM (if no IV access); for opioid overdose: naloxone; for
benzodiazepine toxicity: flumazenil (caution in seizure-risk patients); for status
epilepticus: benzodiazepines first, then fosphenytoin, levetiracetam, or valproate .
6. Anti-infective Agents – Vancomycin inhibits cell wall synthesis (bactericidal; narrow
therapeutic index requires trough monitoring 10-20 mcg/mL); azoles inhibit ergosterol
synthesis; echinocandins inhibit β-1,3-glucan synthesis; amphotericin B + flucytosine for
cryptococcal meningitis; fluoroquinolones carry risk of tendon rupture (especially
elderly, corticosteroids) .
7. Endocrine & Diabetes Pharmacology – SGLT2 inhibitors (empagliflozin, dapagliflozin,
canagliflozin) are recommended for type 2 diabetes with cardiovascular risk; IV regular
insulin for DKA (0.1 units/kg/hr); prednisone causes hyperglycemia via increased
gluconeogenesis and insulin resistance; DKA patients require 8-10 L fluid in first 12
hours; bicarbonate may cause hypokalemia in DKA .

8. Pain, Neurologic & Psychiatric Agents – Fentanyl is preferred for renal failure (hepatic
metabolism, no active metabolites); morphine/codeine have active metabolites that
accumulate in renal impairment; tramadol has serotonergic properties and can
precipitate serotonin syndrome with SSRIs; levetiracetam binds SV2A (modulates
neurotransmitter release) .
9. Medication Safety & Special Populations – ACE inhibitors/ARBs are teratogenic and
contraindicated in pregnancy; pravastatin has lowest CYP3A4 interaction risk; loop
diuretics potentiate aminoglycoside ototoxicity; PPIs irreversibly inhibit H⁺/K⁺-ATPase;
colchicine is first-line for acute gout; drug abuse, misuse, dependence, and tolerance
have distinct definitions .
10. Respiratory & GI Pharmacology – SABA (albuterol) + anticholinergics are first-line for
acute bronchospasm; systemic corticosteroids reduce airway inflammation; PPIs reduce
gastric acid secretion; treatment of acute gout: colchicine reduces inflammation via
microtubule inhibition .
100 MCQ Questions with Rationales
Question 1
A patient on warfarin therapy has an INR of 1.5. What is the most appropriate action?
A) Administer vitamin K 10 mg IV
B) Increase the warfarin dose
C) Continue the current dose; INR is therapeutic
D) Hold the warfarin dose and notify the provider
Correct Answer: B
Rationale: The therapeutic INR range for most indications is 2.0–3.0. An INR of 1.5 is
subtherapeutic, indicating that the warfarin dose should be increased. Warfarin works by
blocking vitamin K-dependent carboxylation of factors II, VII, IX, and X .

Question 2
Which laboratory test is used to monitor unfractionated heparin therapy?
A) Prothrombin time (PT)/INR
B) Activated partial thromboplastin time (aPTT)
C) Thrombin time
D) D-dimer
Correct Answer: B
Rationale: Unfractionated heparin is monitored using the aPTT, with a therapeutic goal of 1.5–
2.5 times the normal control value. Heparin binds to antithrombin III and accelerates its
inactivation of thrombin (factor IIa) and factor Xa .
Question 3
A patient is receiving vancomycin. What is the primary reason for therapeutic drug monitoring?
A) Vancomycin is inexpensive and easily measured
B) Vancomycin has a narrow therapeutic index and requires monitoring to avoid toxicity and
ensure efficacy
C) Vancomycin is administered orally
D) Vancomycin has no side effects
Correct Answer: B
, Page 4 of 134
Rationale: Vancomycin has a narrow therapeutic index and requires monitoring to avoid
nephrotoxicity and ototoxicity. Vancomycin is bactericidal by inhibiting cell wall synthesis .
Question 4
Which medication is the first-line IV vasopressor for septic shock?
A) Dopamine
B) Norepinephrine
C) Vasopressin
D) Dobutamine
Correct Answer: B
Rationale: Norepinephrine is the first-line vasopressor for septic shock because it increases
systemic vascular resistance and MAP without significantly increasing heart rate. It is preferred
over dopamine due to a better safety profile and outcome data .
Question 5
What is the mechanism of action of digoxin?
A) Beta-adrenergic blockade
B) Inhibition of the Na⁺/K⁺ ATPase pump, increasing intracellular calcium and myocardial
contractility
