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 B
Explanation
A. Relieves nasal congestion
Dornase alfa is not used to relieve nasal congestion. It is specifically designed to address the thick, sticky mucus that can accumulate in the airways of individuals with cystic fibrosis (CF).
B. Decreases thick secretions
This is the correct answer. Dornase alfa is known for its ability to decrease the viscosity of thick secretions in the airways of individuals with CF. By breaking down the DNA within the mucus, it helps to thin and improve the clearance of the mucus.
C. Decreases pain
Dornase alfa is not primarily used to decrease pain. Its main action is related to improving respiratory function by reducing the thickness of mucus, which can help ease breathing difficulties associated with CF.
D. Suppresses cough
Dornase alfa is not used to suppress cough. In fact, it may increase coughing initially as it facilitates the loosening and clearance of mucus from the airways.
Correct Answer is A
Explanation
A. “I will not need to know how to check my body temperature.”:
This statement is incorrect. Monitoring body temperature is important for patients receiving chemotherapy because a compromised immune system increases the risk of infection. Fever can be an early sign of infection, and patients are often instructed to monitor their temperature regularly.
B. “Chemotherapy is excreted in my bodily fluids.”:
This statement is correct. Chemotherapy drugs can be excreted in various bodily fluids, such as urine, sweat, and saliva. Patients are advised to take precautions to avoid exposing others to these bodily fluids during and shortly after chemotherapy.
C. “My spouse will wear gloves when emptying my urinal.”:
This statement is correct. To reduce the risk of exposure to chemotherapy drugs in urine, it is advisable for caregivers, such as spouses, to wear gloves when handling bodily fluids.
D. “The chemotherapy will remain in my body for 2-3 days.”:
This statement is correct. The duration during which chemotherapy remains in the body can vary depending on the specific drugs administered. Patients are typically provided with guidelines on how long they need to take precautions to minimize exposure to others.
