____     1.   The nurse is caring for a patient who asks, “The doctor said I have leucopenia; what does that mean?” Which of the following responses by the nurse is best?

A.	“That means your white blood cell count is higher than normal.”
B.	“You have a lot of white blood cells that are very immature so your risk of infection is high.”
C.	“It means your body is building new white blood cells to fight infection.”
D.	“Your risk of infection is higher than normal because your body doesn’t have many white blood cells.”

 

 

____     2.   A student nurse is caring for a patient with bacterial meningitis. Which of the following lab results may be expected and would indicate a left shift in the differential?

C.	The number of lymphocytes is higher than normal.
D.	The number of monocytes is higher than normal.

MULTIPLE CHOICE

 

1. ANS:  D

 

	Feedback
A	When the WBC count is elevated above normal, it is termed leukocytosis; when it is below normal, it is called leucopenia.
B	When the WBC count is elevated above normal, it is termed leukocytosis; when it is below normal, it is called leucopenia.
C	When the WBC count is elevated above normal, it is termed leukocytosis; when it is below normal, it is called leucopenia.
D	When the WBC count is elevated above normal, it is termed leukocytosis; when it is below normal, it is called leucopenia. Chapter Objectives: Explain the nurse’s role and responsibilities in relation to diagnostic tests. Discuss aspects of diagnostic tests and procedures that the nurse should teach the patient.

2. ANS:  A

 

	Feedback
A	Neutrophils elevate with infection. Slightly immature neutrophils are called bands; when their level is elevated, as opposed to the more mature segmented neutrophils, it is known as a left shift, which generally indicates bacterial infection. Chapter Objectives: Explain all the components of a complete blood cell count, including a white count differential. Contrast the functions of the five types of white blood cells.
B	Neutrophils elevate with infection. Slightly immature neutrophils are called bands; when their level is elevated, as opposed to the more mature segmented neutrophils, it is known as a left shift, which generally indicates bacterial infection.
C	Neutrophils elevate with infection. Slightly immature neutrophils are called bands; when their level is elevated, as opposed to the more mature segmented neutrophils, it is known as a left shift, which generally indicates bacterial infection.
D	Neutrophils elevate with infection. Slightly immature neutrophils are called bands; when their level is elevated, as opposed to the more mature segmented neutrophils, it is known as a left shift, which generally indicates bacterial infection.

3. ANS:  B

 

	Feedback
A	Viral infections usually cause an increase in lymphocytes.
B	Lymphocytes increase with viral infections and allergic conditions; when elevated it is known as a right shift, a typical indicator of viral infection. Chapter Objective: Explain all the components of a complete blood cell count, including a white count differential.
C	Viral infections usually cause an increase in lymphocytes.

4. ANS:  C

 

	Feedback
A	Altered hemoglobin levels will not change skin integrity.
B	Altered hemoglobin levels will not change infection risk.
C	When Hgb is decreased, the body’s oxygen-carrying capacity is reduced, which interferes with the ability of different body tissues and systems to function at optimal level. Chapter Objective: Explain the nurse’s role and responsibilities in relation to diagnostic tests.
D	Altered hemoglobin levels will not change nutrition.
