A child has been diagnosed with acute lymphoblastic leukemia and is being treated with chemotherapy. Because many chemotherapeutic agents cause bone marrow suppression, the nurse, before administering the chemotherapy, will determine if this child has any infection-fighting capability by monitoring the:

Absolute neutrophil count (ANC)

Eosinophils

Red blood cell count (RBC)

Hemoglobin (Hgb)

Answer and Explanation

The Correct Answer is A

A. The absolute neutrophil count (ANC) is the best indicator of a child's ability to fight infection. Neutrophils are a type of white blood cell crucial for fighting bacterial infections, and chemotherapy can suppress bone marrow production of neutrophils. The ANC helps assess the risk for infection and the need for additional precautions, such as infection control.

B. Eosinophils are a type of white blood cell that primarily respond to allergies and parasitic infections, and their count is not used to assess infection risk in chemotherapy patients.

C. The red blood cell count (RBC) is important for assessing oxygen-carrying capacity but does not directly relate to infection-fighting ability.

D. Hemoglobin (Hgb) reflects the oxygen-carrying capacity of the blood, not the body's ability to fight infection.

Correct Answer is A

Explanation

A. "Intussusception occurs when one segment of the intestine slides into another, which can cut off blood supply." is the correct explanation. Intussusception occurs when a part of the intestine telescopes into an adjacent section, causing a blockage that can cut off blood supply and lead to tissue death. This is a medical emergency requiring prompt treatment.

B. "Intussusception results from the twisting of the intestine, causing a blockage in the passage of food." is incorrect. While intussusception causes a blockage, it does not result from twisting; it involves one segment of the intestine sliding into another.

C. "Intussusception is a congenital condition where the layers of the intestinal wall do not form properly." is incorrect. Intussusception is not congenital in nature; it can occur in otherwise healthy infants and children but is not a result of improper formation of the intestinal wall layers.

D. "Intussusception is a consequence of weakened abdominal muscles, allowing a portion of the intestine to bulge." is inaccurate. Intussusception does not result from weakened abdominal muscles but rather from one part of the intestine slipping into another, which may cause the blockage and reduced blood flow.

A. Laxatives B. Thyroid replacement medications C. Diuretics D. Pain medications

Correct Answer is D

Explanation

A. Laxatives are not typically used for sickle cell crisis unless the client is experiencing constipation, which is unrelated to the crisis itself.

B. Thyroid replacement medications are used for hypothyroidism and would not be a first-line treatment for sickle cell crisis.

C. Diuretics may be used in conditions like heart failure or kidney disease, but they are not indicated for sickle cell crisis and may worsen dehydration.

D. Pain medications are the correct intervention during a sickle cell crisis. The crisis involves severe pain due to the sickling of red blood cells blocking blood flow to tissues. Opioids like morphine and hydromorphone are commonly administered to manage the severe pain.
