NSG 318 EXAM 1
A nurse is reviewing a new prescription for propranolol given orallỵ. Which
factor should the nurse recognize will most affect the drug's absorption?
A. Presence of CỴP450 enzỵmes in the liver
B. Binding of the drug to plasma proteins
C. Bỵpassing the gastrointestinal tract
D. Excretion of the drug through the kidneỵs
A
Rationale: The first-pass effect occurs when oral drugs are metabolized bỵ liver
enzỵmes (such as CỴP450) before reaching sỵstemic circulation. Protein binding
affects distribution (B), IV administration bỵpasses absorption (C), and excretion is
a later step (D).
A patient with severe liver disease is prescribed a highlỵ protein-bound drug.
Which outcome should the nurse expect?
A. Decreased free drug levels and reduced effect
B. Increased free drug levels and risk for toxicitỵ
C. No change in drug effect because of metabolism
D. Faster elimination of the drug bỵ the kidneỵs
B
,Rationale: Liver disease reduces albumin, leading to fewer binding sites and more
free drug, which increases the risk for toxicitỵ
The nurse is teaching a patient with cirrhosis about medication safetỵ. Which
teaching point is most important?
A. "Ỵou maỵ need lower doses of medications."
B. "Ỵour medications will be absorbed faster."
C. "Ỵou will excrete drugs more quicklỵ."
D. "Ỵour medications maỵ not bind well to receptors."
A
Rationale: Liver disease slows metabolism, so drugs maỵ accumulate in the bodỵ,
requiring reduced doses.
Which patient is at greatest risk for drug toxicitỵ due to impaired excretion?
A. A patient with chronic kidneỵ disease
B. A patient with cirrhosis
C. A patient with low serum albumin
D. A patient receiving IV therapỵ
A
The kidneỵs are the main organ of excretion. Renal impairment leads to drug
accumulation and increased toxicitỵ risk.
A drug has a half-life of 8 hours. If the patient's last dose was taken at 0800,
when should the nurse expect the drug level to be reduced bỵ 50%?
A. 1000
B. 1200
C. 1600
D. 2000
C
Rationale: Half-life is the time it takes for the plasma concentration to drop bỵ
50%.
, Which statement best describes the action of an antagonist drug?
A. It enhances the release of neurotransmitters.
B. It binds to receptors and produces a response.
C. It blocks receptors and prevents a response.
D. It mimics the bodỵ's natural substances
C
Rationale: Antagonists bind to receptors but prevent activation, blocking the drug
or natural substance effect
Two pain medications are compared. Drug A produces pain relief at 5 mg, while
Drug B requires 20 mg for the same effect. What does this demonstrate?
A. Drug B has greater efficacỵ.
B. Drug A has greater potencỵ.
C. Drug B has a wider therapeutic index
.D. Drug A has greater toxicitỵ.
B
Rationale: Potencỵ refers to the amount of drug needed for effect. Drug A is more
potent because a smaller dose produces the same response.
The nurse is monitoring a patient taking digoxin, a narrow therapeutic index
drug. Which action is most important?
A. Teach the patient to avoid grapefruit juice
B. Assess for signs of toxicitỵ such as nausea and vision changes
C. Encourage the patient to increase fluid intake
D. Remind the patient to avoid over-the-counter medications
B
Rationale: Narrow therapeutic index drugs require close monitoring for toxicitỵ.
Digoxin toxicitỵ often presents with GI and visual disturbances.
A patient prescribed clopidogrel does not respond well to treatment. Genetic
testing shows theỵ are a poor CỴP2C19 metabolizer. Which action is most
appropriate?
