Pharmacology Exam 3 Questions And
Answers
What do antobiotics treat?
Bacterial Infetions
What is croup caused by?
human parainfluenza virus
What is epiglottitis caused by?
Haemophilus influenza
Describe Broad vs. Narrow spectrum antibiotics.
Broad spectrum kills a wide range of bacteria and narrow spectrum kills a specific
strand (targeted)
What causes antibiotic resistance?
Taking antibiotics when not appropriate, Not completing antibiotic regimen in its entirety,
Overuse of broad spectrum antibiotics, narrow spectrum (maybe)
List objective symptoms
Fever, Increased WBC, Hypoxemia
List subjective symptoms
Dyspnea, Pain, fatigue, malaise
What does objective and subjective mean?
Subjective is what the patient says they are expirencing and objective is what is
observed by the provider or evidence from assessment
What do chromotropic drugs effect?
Heart Rate (can be increased or decreased)
What do inotropic drugs effect?
, Force of contraction (can be increased or decreased)
What do dromotropic drugs effect?
Rate of conduction (rhythm) (can be increased or decreased)
Action potential:
Contraction and relaxtation by using ions moving in and out of cells
depolarization vs repolarization
contraction vs relaxation
Automaticity definition
Ability to generate pace-making activity
Define antiarrhythmic agents
They reduce arrhythmias
What does the suffix -lol mean?
B-blocker
Digoxin characteristics include
One of the oldest inotropic drugs (cardiac glycoside), increased CO Increases force of
contraction, Slows ventricular rate, antiarrythmic drug
Adenosine characteristics include
Converts SVT, Slows SA to AV conduction antiarrythmic drug
What does HF cause?
Causes blood volume within heart to increase, Heart enlarges, Less blood gets to rest
of the body, Affects kidneys, Edema
What are the pharmacologic treatments for HF?
Removing sodium and water (diuretics), Increasing contraction of the heart (positive
inotropic), decreaseing vascular resistance (vasodialators)
