Exam Questions and Answers
1: What is the primary focus of NUR 807 at MCPHS?--- correct
precise answer ---
The primary focus of NUR 807 at MCPHS is advanced pharmacology,
emphasizing the safe and effective use of medications in various
clinical settings.
2: What are the key components of a comprehensive medication
assessment?--- correct precise answer ---
Key components include patient history, current medications,
allergies, potential drug interactions, and assessment of renal and
hepatic function.
3: How does pharmacokinetics differ from pharmacodynamics?---
correct precise answer --- Pharmacokinetics involves the absorption,
,distribution, metabolism, and excretion of drugs, while
pharmacodynamics is the study of the physiological effects of drugs
and their mechanisms of action.
4: What is the significance of the therapeutic index in
pharmacology?--- correct precise answer ---
The therapeutic index indicates the safety margin of a drug,
representing the ratio between the toxic dose and the therapeutic
dose.
5: What factors can influence drug metabolism?--- correct precise
answer ---
Factors include age, genetic variations, liver function, concurrent
drug use, and lifestyle factors such as diet and smoking.
6: Describe the role of cytochrome P450 enzymes in drug
metabolism. Cytochrome P450 enzymes are responsible for the
oxidative metabolism of many drugs, affecting their clearance and
potential interactions.
7: What is meant by first-pass effect?--- correct precise answer ---
The first-pass effect refers to the initial metabolism of a drug by
the liver, reducing its concentration before it reaches systemic
circulation.
8: How does renal impairment affect drug clearance?--- correct
precise answer ---
, Renal impairment can reduce drug clearance, leading to
accumulation and potential toxicity, necessitating dosage
adjustments.
9: What are the common side effects of beta-blockers?--- correct
precise answer ---
Common side effects include bradycardia, fatigue, dizziness, and
cold extremities.
10: Why is it important to monitor INR levels in patients on
warfarin?--- correct precise answer --- Monitoring INR levels
ensures that patients remain within the therapeutic range,
minimizing the risk of bleeding or thromboembolic events.
11: What is the mechanism of action of ACE inhibitors?--- correct
precise answer ---
ACE inhibitors block the conversion of angiotensin I to angiotensin
II, leading to vasodilation and reduced blood pressure.
12: How do calcium channel blockers help in treating
hypertension?--- correct precise answer ---
They prevent calcium from entering cells of the heart and blood
vessel walls, resulting in decreased heart rate and vasodilation.
13: What are the contraindications for the use of NSAIDs?--- correct
precise answer --- Contraindications include peptic ulcer disease,
renal impairment, and hypersensitivity reactions.
