1. The school nurse is discussing testicular self-examination with adolescent boys. Why is this important?

a. Epididymitis is common during adolescence.

b. Asymptomatic sexually transmitted diseases may be present.

c. Testicular tumors during adolescence are generally malignant.

d. Testicular tumors, although usually benign, are common during adolescence. ANS: C

Tumors of the testes are not common, but when manifested in adolescence, they are generally malignant and demand immediate evaluation. Epididymitis is not common in adolescence. Asymptomatic sexually transmitted disease would not be evident during testicular self-examination. The focus of this examination is on testicular cancer.

Testicular tumors are most commonly malignant. DIF: Cognitive Level: Apply REF: p. 842

2. Which is the usual presenting symptom for testicular cancer?

a. Hard, painful mass

b. Hard, painless mass

c. Epididymis easily palpated

d. Scrotal swelling and pain ANS: B

The usual presenting symptom for testicular cancer is a heavy, hard, painless mass that is either smooth or nodular and palpated on the testes. A hard, painful mass, an epididymis easily palpated, and scrotal swelling and pain are not the clinical presentations of testicular cancer.

3. Which is most descriptive of the pathophysiology of leukemia?

a. Increased blood viscosity occurs.

b. Thrombocytopenia (excessive destruction of platelets) occurs.

c. ,Unrestricted proliferation of immature white blood cells (WBCs) occurs.

d. First stage of coagulation process is abnormally stimulated. ANS: C

Leukemia is a group of malignant disorders of the bone marrow and lymphatic system. It is defined as an unrestricted proliferation of immature WBCs in the blood-forming tissues of the body. Increased blood viscosity may occur secondary to the increased number of WBCs. Thrombocytopenia may occur secondary to the overproduction of WBCs in the bone marrow. The coagulation process is unaffected by leukemia.

4. A boy with leukemia screams whenever he needs to be turned or moved. Which is the most probable cause of this pain?

a. Edema

b. Bone involvement

c. Petechial hemorrhages

d. Changes within the muscles ANS: B

The invasion of the bone marrow with leukemic cells gradually causes a weakening of the bone and a tendency toward fractures. As leukemic cells invade the periosteum, increasing pressure causes severe pain. Edema, petechial hemorrhages, and changes within the muscles would not cause severe pain.

5. Myelosuppression, associated with chemotherapeutic agents or some malignancies such as leukemia, can cause bleeding tendencies because of a(n):

a. decrease in leukocytes.

b. increase in lymphocytes.

c. vitamin C deficiency

d. decrease in blood platelets ANS: D

The decrease in blood platelets secondary to the myelosuppression of chemotherapy can cause an increase in bleeding. The child and family should be alerted to avoid risk of injury. Decrease in leukocytes, increase in lymphocytes, and vitamin C deficiency would not affect bleeding tendencies.

DIF: Cognitive Level: Apply REF: p. 828

6. A child with leukemia is receiving triple intrathecal chemotherapy consisting of methotrexate, cytarabine, and hydrocortisone. What will the triple intrathecal chemotherapy prevent?

a. Infection

b. Brain tumor

c. Drug side effects

d. Central nervous system (CNS) disease ANS: D

For certain children, CNS prophylactic therapy is indicated. This drug regimen is used to prevent CNS leukemia and will not prevent infection or drug side effects. If the child has a brain tumor in addition to leukemia, additional therapy would be indicated.

7. A young boy will receive a bone marrow transplant (BMT). This is possible because one of his older siblings is a histocompatible donor. Which is this type of BMT called?

a. Syngeneic -twin

b. Allogeneic -another individual

c. Monoclonal -made up

d. Autologous -own marrow ANS: B

Allogeneic transplants are from another individual. Because he and his sibling are histocompatible, the BMT can be done. Syngeneic marrow is from an identical twin. There is no such thing as a monoclonal BMT. Autologous refers to the individual's own marrow. DIF: Cognitive Level: Understand REF: p. 824
