A patient with a history of cardiac disease is being evaluated for chronic leukemia.
The patient reports tachycardia and dyspnea. A complete blood cell count with
differential is obtained. Which of the following findings would most likely indicate
the cause?
A. Hemoglobin level, 7.9 g/dl
B. Platelet count, 1000,000 mm3
C. White blood cell count, 2960 mm3
D. Absolute neutrophil count, 1700/mm3 - correct-answer - A. Hemoglobin level,
7.9 g/dl
Anemia is defined as a reduction in the normal concentration of hemoglobin
(Hgb) or red blood cells in the blood. Severe anemia is defined as an Hgb level
,2|Page
below 8 g/dl. Clinical signs of severe anemia include: tachycardia, dyspnea at rest,
angina, headache, and dizzyness.
A patient with lung cancer is scheduled to receive her fourth dose of
chemotherapy. The patient tells the nurse that she has begun to experience
nausea when driving to her appointments. Which of the following types of nausea
is the patient experiencing?
A. Acute
B. Delayed
C. Anticipatory
D. Breakthrough - correct-answer - C. Anticipatory
Patterns of nausea and vomiting range in etiology and duration. Acute nausea and
vomiting occurs within several minutes to several hours after drug administration.
Delayed nausea and vomiting develops after more than 24 hours after drug
administration. Breakthrough nausea and vomiting occurs when preventative
,3|Page
regimens fail. Anticipatory nausea and vomiting is a conditioned response that
occurs prior to the administration of chemotherapy.
A patient with a history of ovarian cancer reports being bloated and feeling full
and vomiting after eating small amounts of food. The patient has noticed a 10
pound weight gain over the last week and states she is eating less. The nurse
instructs the patient to:
A. come to the clinic.
B. call if her ankles swell.
C. eat small, frequent meals.
D. report any further weight gain. - correct-answer - A. Come to the Clinic
The incidence of bowel obstruction is reported between 5.5% and 42% of patients
with ovarian cancer. Signs and symptoms of bowel obstruction depend on the
location of the obstruction, and include vomiting, distention, colicky pain, and
diarrhea. Medical treatment of an intestinal obstruction consists of relieving the
, 4|Page
distention, correcting the fluid imbalances, and removing the source of the
obstruction.
During counseling, a patient with breast cancer asks the nurse, "After I finish
chemotherapy, how long should I wait to get pregnant?" The nurse's best
response is:
A. "Infertility is a permanent side effect of your therapy."
B. "Pregnancy will increase your chance of recurrence."
C. "You should wait at least one year."
D. "No delay in necessary." - correct-answer - C. "You should wait at least one
year."
There appears to be no decrease in survival for women who become pregnant
following treatment. Further pregnancy may actually protect against recurrence.
For those desiring future pregnancies, it is recommended to wait one to five years
following cessation of all treatment.
