NR567 Advanced Pharmacology for
the AGACNP, Final Examination
2026/2027 – 75 Multiple-Choice
Questions with Answers and
Rationales
Question 1
A 68-year-old patient with septic shock is not responding to initial
fluid resuscitation. According to current 2025/2026 Surviving
Sepsis Campaign guidelines, which intravenous vasopressor is
recommended as the first-line agent to restore mean arterial
pressure (MAP)?
A. Dopamine
B. Norepinephrine
C. Vasopressin
D. Dobutamine
Answer: B
Rationale: Norepinephrine is the first-line vasopressor for septic
shock because it increases systemic vascular resistance (SVR) and
MAP without causing significant tachycardia or excessive
vasoconstriction. Dopamine is associated with higher rates of
arrhythmias and increased mortality in certain populations.
Vasopressin may be added as a second-line agent, and
,dobutamine is used primarily for cardiogenic shock with low
cardiac output, not as a first-line vasopressor in septic shock.
Current sepsis guidelines strongly recommend norepinephrine as
the initial agent of choice.
Question 2
A patient with severe hepatic failure is prescribed a medication
that undergoes extensive first-pass metabolism. Which
pharmacokinetic alteration is expected in this patient?
A. Increased renal excretion of the drug
B. Decreased oral absorption
C. Reduced metabolism and prolonged half-life
D. Increased protein binding
Answer: C
Rationale: Hepatic failure reduces the liver's capacity to
metabolize medications, leading to decreased clearance and a
prolonged half-life of drugs that are hepatically cleared. This can
increase the risk of drug accumulation and toxicity. First-pass
metabolism is particularly affected, resulting in higher-than-
expected bioavailability of orally administered drugs. Protein
binding is often decreased in liver disease due to reduced
albumin production, and absorption is generally not the primary
concern. Renal excretion is not directly affected by hepatic failure
unless the drug or its metabolites are renally cleared.
,Question 3
A 25-year-old pregnant woman presents with a generalized
seizure disorder. Which antiseizure medication is preferred during
pregnancy due to its more favorable teratogenic profile?
A. Phenobarbital
B. Valproate
C. Levetiracetam
D. Topiramate
Answer: C
Rationale: Levetiracetam (Keppra) is preferred during pregnancy
because it has a more favorable teratogenic profile compared to
older agents such as valproate and phenobarbital. Valproate is
associated with a threefold increased risk of major congenital
malformations, most commonly neural tube defects such as spina
bifida, as well as an increased risk of autism spectrum disorder.
Phenobarbital also carries significant teratogenic risks. Topiramate
is associated with cleft lip/palate and low birth weight.
Levetiracetam is often maintained during pregnancy when
clinically indicated, though therapeutic drug monitoring is
recommended due to altered clearance.
Question 4
A patient is brought to the emergency department with altered
mental status, seizure activity, and a history consistent with
chronic alcohol use. Which medication should be administered
, immediately to prevent progression to Wernicke–Korsakoff
syndrome?
A. Folate (folic acid)
B. Chlordiazepoxide (Librium)
C. Thiamine (vitamin B1)
D. Lorazepam (Ativan)
Answer: C
Rationale: Thiamine (vitamin B1) should be administered
immediately to patients with suspected Wernicke’s
encephalopathy or those at risk for Wernicke–Korsakoff
syndrome, particularly patients with chronic alcohol use.
Wernicke’s encephalopathy is caused by thiamine deficiency and
can present with altered mental status, ataxia, and oculomotor
disturbances. If untreated, it can progress to Korsakoff syndrome,
characterized by irreversible memory impairment. While
benzodiazepines such as lorazepam are used for alcohol
withdrawal seizures, thiamine is the specific treatment to prevent
Wernicke–Korsakoff syndrome. Folate deficiency may also occur in
alcohol use disorder, but it is not the immediate priority.
Question 5
A patient presents to the emergency department with methanol
poisoning. Which pharmaceutical agent is not recommended in
the treatment of methanol toxicity?
