NURS 6521N week1
Question 1
1 out of 1 points
A patient who has ongoing pain issues has been prescribed meperidine
(Demerol) IM. How should the nurse best administer this medication?
Response
Feedback: The ventrogluteal site is the preferred site for intramuscular
injection. IM injections necessitate the use of a larger gauge
needle than is required for subcutaneous injections.
Question 2
1 out of 1 points
A nurse has been administering a drug to a patient intramuscularly (IM).
The physician discontinued the IM dose and wrote an order for the drug to
be given orally. The nurse notices that the oral dosage is considerably
higher than the parenteral dose and understands that this due to
Response
Feedback
:
The first-pass effect involves drugs that are given PO and
absorbed from the small intestine directly into the portal venous
system, which delivers the drug molecules to the liver. Once in
the liver, enzymes break the drug into metabolites; they may
become active or may be deactivated and readily excreted from
the body. A large percentage of the oral dose is usually
destroyed and never reaches tissues. Oral dosages account for
this phenomenon to ensure an appropriate amount of the drug
in the body to produce a therapeutic action. Passive diffusion is
the major process through which drugs are absorbed into the
body. Active transport is a process that uses energy to actively
move a molecule across a cell membrane and is often involved
in drug excretion in the kidney. Glomerular filtration is the
passage of water and water-soluble components from the
plasma into the renal tubule.
Question 3
1 out of 1 points
In which of the following patients would a nurse expect to experience
alterations in drug metabolism?
Response
Feedback
:
The liver is the most important site for drug metabolism. If the
liver is not functioning effectively, as with cirrhosis, drugs will
not be metabolized normally and toxic levels could develop.
Drug dosage will have to be altered to ensure normal levels in
the body. The patient with kidney stones and the patient in
acute renal failure would most likely have alterations in drug
excretion. If there are no complications with the cervical cancer
patient, there should be no alterations in drug therapy.
Question 4
1 out of 1 points
A patient who has been admitted to the hospital for a mastectomy has
stated that she has experienced adverse drug effects at various times
during her life. Which of the following strategies should the nurse prioritize
in order to minimize the potential of adverse drug effects during the
patient's stay in the hospital?
Response
Feedback
:
In an effort to minimize the potential of adverse drug effects, it
is necessary to closely monitor the patient. It would be
inappropriate for the nurse to alter the route or frequency of
administration or to encourage herbal remedies that also carry
the potential for adverse effects.
Question 5
1 out of 1 points
The nurse's assessment of a community-dwelling adult suggests that the
client may have drug allergies that have not been previously documented.
What statement by the client would confirm this?
