WGU D398 Pharmacology Exam 94 Questions with Verified
Answers
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
antihistamines GI - CORRECT ANSWER limit quantity of stomach acid generated
Proton Pump Inhibitors - CORRECT ANSWER decrease the amount of acid
produced by the stomach
Opiate Agonists GI - CORRECT ANSWER Delays action of digestive tract
Laxative - CORRECT ANSWER drug used to induce emptying of the intestinal tract
