NU 636 Advanced Pharmacology Questions with
Verified Answers Study Guide Herzing university
Latest Update this year
Introduction
This study guide provides comprehensive practice questions
and verified answers covering core Advanced Pharmacology
concepts for NU 636. Topics include cardiovascular
pharmacology, pharmacokinetics, pharmacodynamics,
diabetes medications, antimicrobial agents, central nervous
system drugs, oncology therapeutics, immunology, and drug
safety principles. The material is organized in a question-and-
answer format, making it an effective resource for exam
preparation and course review.
Exam Questions and Answers
1: What is the primary mechanism of action for beta-
blockers?--- correct precise answer ---
Beta-blockers primarily work by blocking the beta-adrenergic
receptors in the heart, which reduces heart rate, cardiac
output, and blood pressure.
2: How do ACE inhibitors lower blood pressure?--- correct
precise answer ---
ACE inhibitors lower blood pressure by inhibiting the
angiotensin-converting enzyme, which decreases the
,production of angiotensin II, leading to vasodilation and
reduced blood pressure.
3: What are the common side effects of statins?--- correct
precise answer ---
Common side effects of statins include muscle pain, fatigue,
digestive problems, and an increased risk of diabetes.
4: Why are calcium channel blockers used in the treatment of
hypertension?--- correct precise answer --- Calcium channel
blockers are used to treat hypertension because they relax and
widen blood vessels by preventing calcium from entering the
cells of the heart and blood vessel walls.
5: What is the role of diuretics in managing heart failure?---
correct precise answer ---
Diuretics help manage heart failure by reducing fluid overload,
decreasing blood volume, and lowering blood pressure, which
eases the workload on the heart.
6: How do proton pump inhibitors (PPIs) reduce stomach acid
production?--- correct precise answer --- PPIs reduce stomach
acid production by irreversibly blocking the
hydrogen/potassium ATPase enzyme system (the proton pump)
of the gastric parietal cells.
, 7: What is the therapeutic use of selective serotonin reuptake
inhibitors (SSRIs)?--- correct precise answer --- SSRIs are
primarily used to treat depression and anxiety disorders by
increasing serotonin levels in the brain.
8: Describe the mechanism of action of non-steroidal anti-
inflammatory drugs (NSAIDs).
NSAIDs work by inhibiting the cyclooxygenase (COX) enzymes,
which reduces the synthesis of prostaglandins, leading to
decreased inflammation and pain.
9: What is the significance of the therapeutic index in
pharmacology?--- correct precise answer ---
The therapeutic index is a measure of a drugs safety,
calculated as the ratio between the toxic dose and the
therapeutic dose. A higher therapeutic index indicates a safer
drug.
10: How do antiplatelet drugs help prevent thrombosis?---
correct precise answer ---
Antiplatelet drugs prevent thrombosis by inhibiting platelet
aggregation, which reduces the formation of blood clots.
11: What is the difference between bactericidal and
bacteriostatic antibiotics?--- correct precise answer ---
Bactericidal antibiotics kill bacteria directly, while
bacteriostatic antibiotics inhibit bacterial growth, allowing
the immune system to eliminate the pathogens.
