ADVANCED PHARMACOLOGY REVIEW
TEST Q & A
• Question 1
1 out of 1 points
A patient has been receiving regular doses of an agonist for 2 weeks. Which of the following
should the nurse anticipate?
Response
Receptors are not static; they can change or modify their response to a
Feedback:
stimulus. Such change occurs when a receptor is continuously stimulated to
act or continually inhibited from action. Continual stimulation from an
agonist usually makes the receptor desensitized to the drug and thus less
active.
Therefore, the nurse should anticipate a decrease in effectiveness of the drug.
• Question 2
1 out of 1 points
A nurse is discussing with a patient the efficacy of a drug that his physician has suggested,
and he begin taking. Efficacy of a drug means which of the following?
Response Efficacy indicates how well a drug produces its desired effect. Different drugs
, Feedback: have different strengths of attraction or affinity for receptor sites. A drug's
ability to stimulate its receptor is called its intrinsic activity, and the
amount of a drug that must be given to produce a particular response is
called the potency of a drug.
• Question 3
1 out of 1 points
An older adult patient with a history of Alzheimer's disease and numerous chronic health
problems has been prescribed several medications during his current admission to hospital
and recent declines in the patient's cognition have impaired his ability to swallow pills.
Which of the following medications may the nurse crush before administering them to this
patient?
Response
A tablet that is designed for immediate release into the gastric environment is
Feedback:
normally safe to crush and administer to the patient. Enteric coated and
sustained release tablets may not be crushed because doing so compromising
the delayed release into the GI tract that is intended with these medications.
Sublingual medications should be placed under the tongue to dissolve rather
than swallowed.
• Question 4
1 out of 1 points
A patient has been prescribed 1 mg lorazepam (Ativan) sublingual prior to the scheduled
insertion of a peripherally inserted central (PIC) line. How should the nurse direct the patient
when administering this medication?
Response
Sublingual tablets are placed under the tongue where they dissolve and are
Feedback:
absorbed into the bloodstream. Swallowing the pill may render it less
effective, but is not unsafe. It is not recommended to chew and hold
sublingual medications nor to hold them in the mouth for length of time.
, • Question 5
1 out of 1 points
A nurse is caring for a patient who has had part of her small intestine removed due to cancer.
She has also now developed hypertension and has been prescribed a new medication to
decrease her blood pressure. While planning the patient's care, the nurse should consider a
possible alteration in which of the following aspects of pharmacokinetics?
Response Because absorption takes place mostly in the small intestine, there could be
