The severe pain associated with post-herpetic neuropathy is most
effectively treated by:
A. propoxyphene.
B. hydromorphone.
C. amitriptyline.
D. extra-strength acetaminophen. - Correct Answer - C. amitriptyline.
Pain associated with herpes zoster is severe and can be debilitating. The
pain is described as continuous, deep and burning. Opioids are used to
treat acute herpes zoster. Tricyclic antidepressants are used to treat post-
herpetic neuralgia.
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. - Correct Answer - 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
pg. 1
,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).
A patient with lymphoma reports persistent nausea, muscle cramps,
weakness, and paresthesia of the fingers two days after receiving the
first cycle of chemotherapy. The patient most likely is experiencing:
A. hypercalcemia.
B. tumor lysis syndrome.
C. disseminated intravasular coagulation.
D. syndrome of inappropriate antidiuretic hormone secretion. - Correct
Answer - B. tumor lysis syndrome
Tumor lysis syndrome involves a metabolic imbalance that occurs with
the rapid release of intracellular potassium, phosphorus, and nucleic acid
into the blood as a result of tumor cell kill. Early signs and symptoms of
tumor lysis syndrome include the following: muscle cramps, weakness,
nausea and vomiting, diarrhea, lethargy, and paresthesia.
Which of the following is a complication that can occur after a
percutaneous lung biopsy is performed?
A. Pleural effusion
B. Atelectasis
C. Pneumothorax
D. Pneumonia - Correct Answer - C. Pneumothorax
A lung biopsy is performed by inserting a spinal type needle into the
chest cavity to obtain tissue for examination. Air can be introduced into
the chest cavity during the procedure and can cause a pneumothorax.
pg. 2
,While administering doxorubicin peripherally, a patient complains of
itching at the infusion site. The nurse observes red streaking along the
vein with a blood return. The nurse's initial response is to:
A. change the IV site.
B. continue administering the drug.
C. stop the infusion and instill an antidote.
D. stop the infusion and flush the line with saline. - Correct Answer - D.
stop the infusion and flush the line with saline.
A flare reaction is a local venous inflammatory response with
subsequent histamine release manifested by streaking or red blotches
along the vein, but without pain. If it is determined that the drug
administered has not extravasated, then the infusion should stop and the
line should be flushed with saline, while watching for resolution of the
flare.
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 below 8 g/dl. Clinical signs of severe anemia
include: tachycardia, dyspnea at rest, angina, headache, and dizzyness.
pg. 3
, 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 regimens fail. Anticipatory nausea
and vomiting is a conditioned response that occurs prior to the
administration of chemotherapy.
Which of the following medications may be useful in the treatment of
neuropathic pain?
A. codeine 60 mg q 4 hours with an NSAID
B. dexamethasone 16 mg daily
C. an opioid plus carbamazepine 200 mg twice daily
D. diazepam 10 mg at bedtime a hs - Correct Answer - C. an opioid plus
carbamazepine 200 mg twice daily
Carbamazepine used in combination with an opioid is useful in the
treatment of neuropathic pain. Codeine, in combination with a non-
steroid anti-inflammatory agent, may be useful for visceral pain.
Dexamethasone in higher doses is useful in the treatment of increased
intracranial pressure. Diazepam may be utilized in treating muscle
spasms.
