How do targeted therapies treat cancer?
Kill cancer cells and normal cells
Increase neutrophils to fight infection
Target the spread of infection
Block specific cancer cell growth on the molecular level
The Correct Answer is D
A. Kill cancer cells and normal cells
This describes the general mechanism of traditional chemotherapy, which targets rapidly dividing cells. Unlike targeted therapies, traditional chemotherapy does not selectively target specific molecules or pathways in cancer cells, leading to a broader impact on both cancer cells and normal cells.
B. Increase neutrophils to fight infection
This does not describe the mechanism of targeted therapies. Neutrophils are a type of white blood cell involved in the immune response to infection. Targeted therapies primarily focus on blocking specific molecular pathways involved in cancer cell growth and survival.
C. Target the spread of infection
This option is not an accurate description of how targeted therapies treat cancer. The primary goal of targeted therapies is to interfere with specific molecular processes in cancer cells, not to target the spread of infection.
D. Block specific cancer cell growth on the molecular level
This is the correct answer. Targeted therapies are designed to block or interfere with specific molecules or pathways involved in the growth and survival of cancer cells. By targeting these specific aspects of cancer cell biology, targeted therapies aim to inhibit the uncontrolled growth of cancer cells while minimizing damage to normal cells.

Correct Answer is D
Explanation
. because many chemotherapy patients require blood transfusions:
While some chemotherapy patients may require blood transfusions, this is not the primary reason for using intravenous ports, central lines, or peripherally inserted central lines.
B. because many chemotherapy patients need long-term intravenous access:
Long-term intravenous access may be needed for some chemotherapy patients, but the critical consideration is the vesicant nature of many chemotherapy drugs.
C. because chemotherapy patients have frequent blood draws orders:
Frequent blood draws may be necessary for monitoring purposes, but the primary reason for using specialized lines in chemotherapy patients is to administer the drugs safely.
D. because many chemotherapeutic drugs are vesicants:
The primary reason for using intravenous ports, central lines, or peripherally inserted central lines in chemotherapy patients is to administer chemotherapy drugs directly into large veins. Many chemotherapeutic drugs are vesicants, meaning they can cause severe damage to tissues if they leak into the surrounding areas. These specialized lines allow for the safe and controlled administration of chemotherapy drugs, reducing the risk of extravasation (leakage into surrounding tissues).
Correct Answer is D
Explanation
A. Decrease viral load:
This is a goal typically associated with antiviral medications, which aim to reduce the amount of virus in the body, commonly seen in the treatment of viral infections like HIV.
B. Kill tumor cells:
This is the goal of many cancer treatments, such as chemotherapy or radiation therapy. These treatments aim to destroy or inhibit the growth of cancer cells.
C. Increase body defenses:
This is a goal often associated with immunotherapy, which aims to enhance the body's immune system to better recognize and attack cancer cells or other pathogens.
D. Relieve symptoms:
This is the primary goal of palliative therapy, which focuses on managing and alleviating symptoms, improving the patient's comfort and quality of life, especially in the context of serious or life-limiting illnesses like cancer.
