Pharmacology D398 WGU – Questions With
Complete Solutions
Cardiac Glycosides Correct Answer - drugs used to improve
heart output by increasing the muscular contraction
Beta Blockers Correct Answer - decrease heart rate and dilate
arteries by blocking beta receptors
Calcium Channel Blockers Correct Answer - agents that inhibit
the entry of calcium ions into heart muscle cells, causing a slowing
of the heart rate, a lessening of the demand for oxygen and
nutrients, and a relaxing of the smooth muscle cells of the blood
vessels to cause dilation; used to prevent or treat angina pectoris,
some arrhythmias, and hypertension
Diuretics Correct Answer - medications administered to
increase urine secretion in order to rid the body of excess water and
salt
Angiotensin-converting enzyme (ACE) inhibitors Correct Answer
- lower blood pressure by inhibiting the conversion of
angiotensin I (an inactive enzyme) to angiotensin II (a potent
vasoconstrictor)
Angiotensin Receptor Blockers Correct Answer - prevent
angiotensin II from reaching its receptors, causing vasodilation
antiarrhythmic drugs Correct Answer - used to prevent,
alleviate, or correct an abnormal heart rhythm
coronary vasodilators Correct Answer - widen blood arteries
, Antilipemic Statin drugs Correct Answer - suppresses enzyme
for cholesterol production
Antilipemic fibrates Correct Answer - reduce triglycerides and
cholesterol levels
Antithrombotics Correct Answer - A class of drugs used to
dissolve blood clots
Broncodilators Correct Answer - dilates airways
Anticholinergics Correct Answer - reduce bronchospasm
Xanthine Derivatives Correct Answer - relaxes smooth muscle
of bronchial airways and pulmonary blood vessels
Inhaled Corticosteroids Correct Answer - inhibit release of
asthma causing chemicals
Expectorants Correct Answer - liquefy respiratory secretions
so that they are more easily dislodged during coughing episodes
Antitussives Correct Answer - relieve or suppress coughing by
blocking the cough reflex in the medulla of the brain
Antihistamines RS Correct Answer - inhibit allergic reactions
of inflammation, redness, and itching caused by the release of
histamine
Decongestants Correct Answer - constrict blood vessels of
nasal passages and limit blood flow, which causes swollen tissues to
shrink so that air can pass more freely through the passageways
antacid Correct Answer - drug that neutralizes stomach acid
