PHM 350 Exam 1 | 50 Questions | With Complete Solutions
A drug is totally eliminated by excretion in the urine. which of
the following will produce an increase of concentration of free
drug in the plasma? Correct Answers - Reabsorption of drug
from the renal tubule
- Displacement of drug from plasma protein (albumin) binding
sites
A drug used to treat angina pectoris which is a beta 1 selective
adrenoreceptor antagonist Correct Answers Atenolol
(TENORMIN)
A drug which affects heart rate through beta1 adrenoreceptors
AND also induces bronchodilation BUT does not produce
vasoconstriction through actions on vascular adrenergic
receptors: Correct Answers Isoproterenol (ISUPREL)
A drug which does not affect salivary secretion or heart rate but
which increases the lifetime of acetylcholine in the synaptic gap
of the neuromuscular junction Correct Answers None of the
above
A drug which increases heart rate and binds with high affinity to
muscarinic receptors Correct Answers Atropine (Atreza, SAL-
TROPINE)
A drug which increases salivary secretion and which increases
the lifetime of acetylcholine in the synaptic gap of the
neuromuscular junction Correct Answers Physostigmine
(ANTILIRUM)
, A drug which is administered intravenously does not enter the
central nervous system rapidly, does not affect gastrointestinal
motility or pupillary diameter but does effectively block
transmission between motor neurons and skeletal muscle
although it is not a pharmacological antagonist Correct Answers
succinyicholine (ANECTINE)
A drug which will prevent the reflex tachycardia likely to result
from administration intravenously of terbutaline (BRETHINE)
Correct Answers Atenolol (TENORMIN)
An administered drug that activates receptors and initiates a
series of cellular reactions that result in a maximal (100%)
response by the cell/tissue/organ is: Correct Answers a full
agonist
Anticholinesterases (cholinesterase inhibitors) Correct Answers
intensify and prolong the actions of physiologically released
acetylcholine
At an appropriate dose, pyridostigmine (MESTINON) increases
the strength of contraction of skeletal muscle. Pyridostigmine
has this effect because: Correct Answers Pyriostigmine reduces
(i.e., slows) metabolism of acetylcholine released from motor
neurons.
Atracurium (TRACURIUM) Correct Answers - Is used as a
muscle relaxant
