1.
A nurse is caring for an elderly client diagnosed with anemia. The nurse realizes that
the anemia can be attributed to the effects of aging on the hematologic and lymphatic
systems. Which of the following are the other effects of aging on this system?
*Increased incidences of infection
Increased leukocyte production
Increased number of platelets
Increased metabolic rate
Increased incidences of infection are an effect of aging on the hematologic and
lymphatic system. Increased leukocyte production, increased number of platelets, and
increased metabolic rate are not effects of aging on this system. Decreased leukocyte
production, decrease in the number of platelets, and decreased metabolic rate are
effects of aging on the hematologic and lymphatic system.
2.
A complete blood count for a client reveals a high monocyte count. The client wants
to know the function of monocytes. Which of the following should the nurse tell the
client is the role of monocytes?
Involved in allergic reactions
*Involved in phagocytosis
Involved in the clotting of blood
Involved in parasitic infections
Monocytes are transformed into phagocytic cells during an acute and chronic
infection. A high monocyte count may be due to a viral or fungal infection,
tuberculosis, or other chronic diseases. A high monocyte count is not involved in
allergic reactions, clotting of blood, or parasitic infections. Eosinophils are involved
in allergic reactions and parasitic infections. Platelets are involved in the clotting of
blood.

A nurse is caring for a client with rashes due to an allergy. The client has a high
eosinophil count. Which of the following should the nurse explain to the client is the
role of eosinophils? Select all that apply.
To release histamine when foreign invaders attack the body
*To engulf or devour invaders through phagocytosis
*To release chemicals to detoxify foreign proteins
*To decrease the release of chemical mediators during allergic reactions
To help maintain blood pressure and circulating fluid volume in the body
Eosinophils engulf or devour invaders through phagocytosis, release chemicals to
assist the body in detoxifying foreign proteins, and may decrease the release of
chemical mediators during allergic reactions. Eosinophils do not release histamine
when foreign invaders attack the body, nor do they help maintain blood pressure in
the body. Basophils release histamines when foreign invaders attack the body. Plasma
proteins help maintain blood pressure and the circulation of fluid volume in the body.
4.
A nurse is instructing some students in a geriatric setting about the effects of aging on
the blood and lymphatic systems. Which of the following apply?
Increased WBCs
Increased hematopoiesis
Decreased infection
*Decreased blood volume
Aging does not typically have any effect on the WBCs except in the case of an
acquired infection. Hematopoiesis actually declines due to loss of bone marrow with
aging. Infections tend to increase with aging for a variety of reasons. Blood volume
does decrease because of decreased muscle activity and decreased metabolic rate in
the elderly.

A client is diagnosed with inflammation of the spleen. The client asks the nurse about
the functions of the spleen. The nurse knows that which of the following are
functions of the spleen?
To absorb and transport fats to the blood
*To destroy the old and used RBCs
To provide and maintain osmotic pressure
To absorb salts for use by body cells
The RBCs are fragile and wear out quickly. The spleen destroys old and used RBCs.
The life of an individual RBC is about 120 days. The function of the lymphatic
system is to absorb and transport fats to the blood. The function of albumin is to
provide and maintain osmotic pressure. The function of the plasma is to absorb salts
for use by the body cells.
