A 70-year-old patient has just received a drug that can cause sedation. What
would be the priority nursing diagnosis for this patient?
a. Noncompliance: Cost of the drug
b. Deficient knowledge: Unfamiliar with drug therapy
c. Risk for injury: Related to adverse effects of the drug
d. Ineffective health maintenance: Need for medication
c.
Because of the patient's age and that the medication causes sedation, the highest
priority nursing diagnosis is related to maintaining the patient's safety. Safety for the
patient is the nurse's number one concern. There is nothing indicated related to the cost
of the drug or the risk of noncompliance for this patient. Deficient knowledge will need to
be addressed but it is not the priority when compared with patient safety. There is no
indication the patient's need for this medication is related to an ineffective health
maintenance issue.
What is the responsibility of the nurse related to the patient's drug therapy?
(Select all that apply.)
a. Teaching the patient how to cope with therapy to ensure the best outcome
b. Providing therapy as well as medications
c. Evaluating the effectiveness of therapy
d. Altering the drug regimen to optimize outcome
e. Recommending appropriate over-the-counter medications to treat adverse
effects of prescription drug therapy
a, b, c
A nurse is, therefore, a key health care provider who is in a position to assess the whole
patient, to administer therapy as well as medications, to teach the patient how best to
cope with the therapy to ensure the most favorable outcome, and to evaluate the
effectiveness of the therapy. Nurses do not alter drug therapy or recommend over-the-
counter medications because prescribing is outside the nurse's scope of practice.
The nurse is gathering assessment data from a medication history of a 38-year-
old man with four children. What assessment information would be most
,important in providing care for this patient?
a. The medication history of the patient's mother and/or father
b. The name of the patient's pharmacy
c. Insurance, financial support, and stability for the patient and his family
d. The last time the patient was hospitalized
c.
In this situation, insurance, financial support, and stability would be the most important
data and may determine compliance with future drug therapy. The medication history of
the patient's parents could indicate a pattern of overall attitude about drug therapy but is
not the priority concern. The last time the patient was hospitalized could indicate
whether the patient seeks medical care when appropriate or if he self-medicates,
contributing to the nurse's knowledge of this individual but this is not the priority
concern. The name of the pharmacy would be unnecessary unless the nurse anticipates
having to call a prescription in to the pharmacy for the prescriber.
During what phase of the nursing process would the nurse be required to
consider the efficacy of nursing interventions related to drug therapy?
a. Assessment
b. Nursing diagnosis
c. Interventions
d. Evaluation
d.
Evaluation allows the nurse to review what has changed since intervening to determine
whether the nursing care has had a positive, therapeutic effect moving the patient
toward a more healthful life. If outcomes have not improved, the nurse begins again at
the assessment phase of the nursing process with the goal of changing the plan of care
to improve outcomes. The patient's response to the drug and occurrence of adverse
drug effects indicate the effectiveness of the nursing interventions related to drug
therapy. Assessment involves a systematic, organized collection of data concerning a
patient. A nursing diagnosis indicates actual or potential alterations in patient function
based on the assessment of the clinical situation. Interventions are actions taken to
meet the patient's needs, such as administration of drugs.
When the nurse reads in the drug handbook the section related to recommended
dosage, it is important to remember that this suggested dosage is based on
what?
a. A 40-year-old man
b. An average-sized adult
c. A 150-pound adult male
d. A healthy young adult
c.
Drug studies base the therapeutic dosage, or that dose needed to reach a critical
, concentration, on the physiology of a 150-pound healthy adult male. Testing is not
routinely done in women because of the potential for unknown effects on the ova.
Testing would not be done on an obese adult or older adult because of the potential for
underlying disease, altered metabolism, or reactions to the drug. Children and
adolescents are never used for testing due to ethical concerns.
A nurse is caring for a child on the pediatric unit. A drug is ordered for the child,
but no pediatric dose is listed for the drug. To make sure that the right dose has
been ordered, what will the nurse use to calculate the correct dose?
a. Surface area
b. Height
c. Birth date
d. Adult dosage
a.
The surface area of a child is calculated using height and weight. It is the most accurate
way to determine an appropriate dosage for that child. Age does not take into
consideration variations in growth. Height alone does not take into account the mass of
the child. Gestational age is simply a distracter.
You are evaluating the discharge teaching you have done with your patient
concerning drug therapy. What statement from the patient would indicate that
teaching had been effective?
a "I have to take three pills each day and I can take them at the time that fits my
schedule."
b. "I should take the white pill in the morning because the doctor wants me to
take it."
c. "I will add the names and dosages of these new drugs to my medication list in
my wallet."
d. "I have prescriptions at different pharmacies. I shop around for the best price
for each drug."
c.
The patient needs to recognize the importance of keeping an updated list of all current
medications and the need to share this list with all health care providers to avoid drug-
drug interactions. The patient should understand exactly when to take medications, why
that medication is being taken, and how to take it safely. Patients should be encouraged
to use a single pharmacy because this will add another layer of safety because the
pharmacy will know all drugs being prescribed to this patient.
The nurse would expect to see an adjusted dosage in what patients? (Select all
that apply.)
a. Young adult women
b. Middle-aged men
c. Infants
