Questions And Correct Answers
The absorption of some drugs can be significantly reduced by food; these drugs should be taken on an
empty stomach, which is 1 hour or more before a meal or at least 2 hours after a meal. An 8-hour fast is
not necessary; the patient does not need to miss a meal to take the medication; and it is not reasonable
to have the patient on thin liquids for 12 hours.
A nurse is teaching nursing students about the use of nonproprietary names for drugs. The nurse tells
them which fact about nonproprietary names? - correct answer <<<<<💕💕💕✔✔they are
assigned by the U.S adopted names council
Nonproprietary, or generic, names are assigned by the U.S. Adopted Names Council, which ensures that
each drug has only one name. Trade names, or brand names, are approved by the FDA and are easier to
remember. Some nonproprietary names contain syllables that identify the classification, although not all
do. Drug names are not supposed to identify the use for the drug, although some brand names do so.
A nurse is administering an agonist drug that acts on postganglionic neurons of the sympathetic nervous
system. Which response will the nurse expect to see? - correct answer <<<<<💕💕💕✔✔increased
cardiac output
Norepinephrine (NE) is the most common neurotransmitter released by all postganglionic neurons of
the sympathetic nervous system except those going to sweat glands where ACh is the neurotransmitter.
NE acts on alpha1, alpha2, and beta1 receptors to increase the force and rate of cardiac contraction,
thus increasing cardiac output. ACh would increase sweating. Bronchodilation occurs when epinephrine
activates beta2 receptors on bronchial smooth muscle. NE affects alpha1 receptors to dilate the pupils.
A nurse is preparing to administer a medication and learns that it is a nonselective agonist drug. What
does the nurse understand about this drug? - correct answer <<<<<💕💕💕✔✔it directly activates
receptors to affect many physiologic processes
Drugs that directly activate receptors are called agonists, so this drug will directly activate the receptor
site. Drugs that are nonselective activate a variety of receptor sites. A selective agonist would directly
activate specific receptors to affect a specific process. An antagonist would prevent receptor activation.
, A patient who has been taking clonidine [Catapres] for several weeks complains of drowsiness and
constipation. What will the nurse do? - correct answer <<<<<💕💕💕✔✔Recommend that the
patient take most of the daily dose at bedtime.
CNS depression is common with clonidine, but this effect lessens over time. Constipation is also a
common side effect. Patients who take most of the daily amount at bedtime can minimize daytime
sedation. Transdermal forms of clonidine do not alter adverse effects. Patients who are abusing
clonidine often experience euphoria and hallucinations along with sedation, but they generally find
these effects desirable and would not complain about them to a healthcare provider. Clonidine should
not be withdrawn abruptly, because serious rebound hypertension can occur.
What are the properties of an ideal drug? (Select all that apply.) - correct answer
<<<<<💕💕💕✔✔-chemical stability
-predictability
-ease of administration
In addition to predictability, ease of administration, and chemical stability, other properties include a
reversible action so that any harm the drug may cause can be undone and a simple generic name,
because generic names are usually complex and difficult to remember and pronounce.
The nurse administers naloxone [Narcan] to a patient who has received a toxic dose of morphine sulfate.
The nurse understands that the naloxone is effective because of which action? - correct answer
<<<<<💕💕💕✔✔preventing activation of opioid receptors through antagonist actions
Naloxone acts by blocking the action of opioids at opioid receptors. An opioid agonist would increase
the effects of morphine. Naloxone does not affect serum pH or excretion of opioids. Naloxone does not
alter the sensitivity of opioid receptors.
Someone asks a nurse about a new drug that is in preclinical testing and wants to know why it cannot be
used to treat a friend's illness. Which statement by the nurse is correct? - correct answer
<<<<<💕💕💕✔✔"at this stage of drug development, the safety and usefulness of the medication is
unknown"
