NUR 2810 Latest Test Questions Solved 100%
Correct
A patient tells the nurse that the oral drug that has been prescribed has caused a lot of
stomach discomfort in the past. What will the nurse ask the prescriber?
a. Whether a sublingual form of the medication can be given
b. Whether the medication can be given by a parenteral route instead
c. Whether an enteric-coated form of the drug is available
d. Whether the patient can receive a sustained-release preparation of the drug
ANS: C
Enteric-coated drugs are preparations that have been coated with a material that dissolves in the
intestines, not the stomach - protects stomach from drug and vice versa.
A patient claims to get better effects with a tablet of Brand X of a drug than with a tablet of
Brand Y of the same drug. Both brands contain the same amount of the active ingredient.
What does the nurse know to be most likely?
a. Advertising by pharmaceutical companies can enhance patient expectations of one
brand over another, leading to a placebo effect.
,b. Because the drug preparations are chemically equivalent, the effects of the two
brands must be identical.
c. Tablets can differ in composition and can have differing rates of disintegration and
dissolution, which can alter the drug's effects in the body.
d. The bioavailability of a drug is determined by the amount of the drug in each dose.
ANS: C
Even if two brands of a drug are chemically equivalent (i.e., they have identical amounts of the
same chemical compound), they can have different effects in the body if they differ in
bioavailability.
Tablets made by different manufacturers contain different binders and fillers, which disintegrate
and dissolve at different rates and affect the bioavailability of the drug.
A patient is given a prescription for azithromycin [Zithromax] and asks the nurse why the
dose on the first day is twice the amount of the dose on the next 4 days. Which reply by the
nurse is correct?
a. "A large initial dose helps to get the drug to optimal levels in the body faster."
b. "The first dose is larger to minimize the first pass effect of the liver."
,c. "The four smaller doses help the body taper the amount of drug more gradually."
d. "Tubular reabsorption is faster with initial doses, so more is needed at first."
ANS: A
a loading dose is used to help get serum drug levels to plateau levels more quickly.
Larger doses do not prevent first pass effects in drugs susceptible to this type of metabolism.
A nurse is giving an enteral medication. The patient asks why this method is preferable for
this drug. How will the nurse reply?
a. "This route allows more rapid absorption of the drug."
b. "This route is safer, less expensive, and more convenient."
c. "This route is the best way to control serum drug levels."
d. "This route prevents inactivation of the drug by digestive enzymes."
ANS: B
A patient receives a drug that has a narrow therapeutic range. The nurse administering
this medication will expect to do what?
, a. Administer the drug at intervals longer than the drug half-life.
b. Administer this medication intravenously.
c. Monitor plasma drug levels.
d. Teach the patient that maximum drug effects will occur within a short period.
ANS: C
A drug with a narrow therapeutic range is more difficult to administer safely, because the
difference between the minimum effective concentration and the toxic concentration is small.
Patients taking these medications must have their plasma drug levels monitored closely to ensure
that they are getting an effective dose that is not toxic.
A provider has written an order for a medication: drug × 100 mg PO every 6 hours. The
half-life for the drug is approximately 6 hours. The nurse is preparing to administer the
first dose at 8:00 AM on Tuesday. On Wednesday, when will the serum drug level reach
plateau?
a. 2:00 AM
b. 8:00 AM
c. 2:00 PM
d. 8:00 PM
