,Question 1
A nurse is administering medication to a 67-year-old patient in liver failure, secondary to
end-stage cirrhosis. Liver dysfunction can influence drug pharmacokinetics and
pharmacodynamics. Which pharmacokinetic phase is affected in this patient?
A. Nutrition
B. Metabolism
C. Distribution
D. Excretion
Correct Answer: B. Metabolism
Rationale: The liver is the primary site of drug metabolism. Liver failure impairs the
cytochrome P450 system and other metabolic pathways, leading to drug accumulation
and toxicity.
Question 2
A 76-year-old female with HTN and COPD presents with abdominal pain and watery
stools. BMP: Na 140, K 3.3, Cl 90, glucose 155, BUN 46, Cr 1.6, eGFR 40. Meds: lisinopril,
Advair, Spiriva. Vitals stable. Which treatment should the nurse administer first based on
lab results?
A. Elevated Von Willebrand factor
B. Low-dose enteric coated aspirin 81 mg daily
C. Administer intravenous fluids
, D. 5.31 mIU/L
Correct Answer: C. Administer intravenous fluids
Rationale: The patient has elevated BUN/Cr (prerenal azotemia) and hypochloremia,
likely from dehydration. IVF is the priority.
Question 3
Which condition from this patient's medical history is contributing to the loss of
contractility?
A. Acute myocardial infarction
B. Acute hypertensive crisis
C. Congestive heart failure
D. Pulmonary embolism
Correct Answer: C. Congestive heart failure
Rationale: CHF directly reduces myocardial contractility due to心室 dysfunction and
remodeling.
Question 4
SOB when lying down and moving around. Which disease process is the patient likely
exhibiting?
A. Glaucoma
B. Pneumonia
C. Bronchitis
D. Asthma
Correct Answer: D. Asthma
Rationale: Dyspnea on exertion and when lying down (though orthopnea is more CHF)
with movement suggests reactive airway disease.
, Question 5
Which hospitalized patient is highest risk for developing delirium?
A. An elderly male with COVID-19
B. A woman recently diagnosed with schizophrenia
C. A depressed Hispanic woman
D. A 70-year-old diabetic patient
Correct Answer: A. An elderly male with COVID-19
Rationale: Delirium is associated with autonomic overactivity, infection (COVID-19), ICU
stays, surgery, or CNS depressant withdrawal. Elderly + infection = high risk.
Question 6
(ECG finding with ventricular depolarization abnormality)
A. Absence of P waves
B. Short PR interval
C. QT interval variability
D. Prolonged QRS interval
Correct Answer: D. Prolonged QRS interval
Rationale: QRS represents ventricular depolarization. Prolonged QRS suggests bundle
branch block, heart failure, or MI.
Question 7
Sulfonylureas for type 2 diabetes:
A. Antagonist of insulin receptor site activity
B. A drug category that enhances insulin release
