Rationales
Multiple Choice
1. A nurse is caring for a patient with a diagnosis of chronic myelogenous leukemia (CML). The
patient was admitted to an acute care unit with a temperature of 100.4°F (38°C) and weight loss
over the past 2 to 3 months. The nurse notes that the patient’s white blood cell (WBC) count is
23 103/microL (SI = 23 109/L), and the physical examination shows splenomegaly. The
priority nursing intervention should be:
1. avoiding falls.
2. managing pain.
3. preventing infection.
4. promoting adequate nutrition.
ANS: 3
Page: 1245
Feedback
1. This is incorrect. Although avoiding falls is important, it is not the main priority
for a patient presenting with a diagnosis of CML and leukocytosis. Preventing
opportunistic infections should be the priority.
2. This is incorrect. Although managing pain is important, it is not the main priority
for a patient presenting with a diagnosis of CML and leukocytosis. Preventing
opportunistic infections should be the priority.
3. This is correct. The nurse’s priority should be planning interventions to prevent
opportunistic infections for the patient with CML and significant leukocytosis.
4. This is incorrect. Although promoting adequate nutrition is important, it is not
the main priority for a patient presenting with a diagnosis of CML and
leukocytosis. Preventing opportunistic infections should be the priority.
2. A patient with diabetes requires assessment of long-term glucose control. Which test would be
most appropriate for this patient?
1. Glycated hemoglobin (Hgb)
2. Glucose
3. Glucose-6-phosphate dehydrogenase (G6PD)
4. Glucose tolerance test
ANS: 1
Page: 630
Feedback
1. This is correct. Glycated hemoglobin is used to indicate long-term glycemic
management.
2. This is incorrect. Glucose levels are used to assist in the diagnosis of
diabetes and to evaluate disorders of carbohydrate metabolism such as
malabsorption syndrome
3. This is incorrect. Glucose-6-phosphate dehydrogenase is used to identify an
enzyme deficiency that can result in hemolytic anemia.
4. This is incorrect. The glucose tolerance test is used to evaluate blood
glucose levels to assist in diagnosing diabetes.
