VERSION |GUARANTEED PASS.
An oncology nurse teaching a cancer biology class explains that a proto- oncogene's
role is to:
A. stimulate angiogenesis.
B. cause apoptosis.
C. inhibit tumor growth.
D. promote cell division.
D. promote cell division
Proto-oncogenes promote the specialization and division of normal cells. A
change in a proto-oncogenes genetic sequence can result in uncontrolled
cell growth, ultimately causing the formation of a cancerous tumor. Proto-
oncogenes can be transformed into oncogenes in three ways: point
mutation (alteration of a single nucleotide base pair), translocation (in which a
segment of the chromosome breaks off and attaches to another
chromosome), or amplification (increase in the number of copies of the
proto-oncogene).
,Which of the following statements by a patient most likely indicates the need
for further education about preventing infection?
A. I need to be very diligent about washing my hands after working in the garden.
B. I do not want to get an influenza shot until all my chemotherapy is finished.
C. I keep my wound dressing supplies in a closed storage container.
D. I will not permit my grandchildren to visit me if they are sick.
B. I do not want to get an influenza shot until all my chemotherapy is finished
Because a percentage of patients will achieve protection from the influenza
vaccination and the risks for adverse effects are low, all patients with cancer and
their household contacts should receive annual vaccination. NCCN
recommends vaccination at least two weeks prior to cytotoxic or
immunosuppressive. If this is not possible, patients can be vaccinated during treatment
and revaccinated at least three months after therapy.
,A 69-year-old patient who received chemotherapy seven days ago calls the
nurse to report a temperature of 101°F (38.3°C) and lightheadedness. The
nurse determines the patient is dyspneic and diaphoretic. The nurse's initial response is
to instruct the patient to:
A. take acetaminophen.
B. recheck his temperature in two hours.
C. report to the emergency department.
D. call for an ambulance.
D. call for an ambulance.
The time at which chemotherapy exerts its maximum effect on the bone
marrow and the white blood count reaches its lowest point is the nadir. This
usually occurs within 7 to 10 days after administration. Patients are most
susceptible to infections at this time due to neutropenia. In a neutropenic
patient, infection may rapidly progress to sepsis, a systemic inflammatory
response to microorganisms in the blood. Early signs of sepsis include fever,
chills, and tachypnea. Patients over the age of 65 are at greater risk.
Untreated sepsis can result in septic shock and death. Immediate reporting of
symptoms and medical management is necessary.
, A patient expresses anger about his diagnosis of cancer and the need to receive
his first chemotherapy treatment. The nurse's best response is to:
A. initiate a referral to a social worker.
B. call the physician and ask for the treatment to be delayed.
C. explain to the patient that the doctor ordered treatment to start today.
D. suggest ways for the patient to participate in the treatment plan.
D. suggest ways for the patient to participate in the treatment plan.
Loss of personal control is perceived as lacking the ability to control events that
affect life style and goals. Both disease and treatment are considered risk
factors for a loss of personal control. Personal control can be
maintained through verbalization of feelings and participation in care.
