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 A
Explanation
A. To help prevent Tumor Lysis Syndrome.
Encouraging fluid intake is crucial for patients undergoing chemotherapy, especially when there's a risk of Tumor Lysis Syndrome (TLS). TLS is a potentially serious complication that can occur when cancer cells release their contents into the bloodstream, leading to metabolic imbalances. Adequate hydration helps prevent the concentration of these released substances and reduces the risk of TLS.
B. Staying hydrated decreases oral dryness that the patient may exhibit as a result of chemotherapy.
While hydration is generally important for overall well-being, oral dryness is not typically a direct consequence of bladder cancer chemotherapy. It might be a side effect of certain medications, but the primary concern in this case is likely related to preventing TLS.
C. To help prevent new onset diabetes mellitus.
The rationale for fluid intake in the context of bladder cancer chemotherapy is not typically related to preventing new onset diabetes mellitus. The primary focus is usually on managing potential side effects of chemotherapy and promoting overall health.
D. Because it is better to encourage water Vs. carbonated beverages.
While encouraging water over carbonated beverages is generally a healthy choice, the primary rationale for increased fluid intake in the context of bladder cancer chemotherapy is more specific and related to preventing Tumor Lysis Syndrome.
Correct Answer is C,A,B
Explanation
The correct order for administering ipratropium bromide (Atrovent), albuterol (Proventil), and an inhaled glucocorticoid (steroid) to treat chronic bronchitis is:
C. Ipratropium bromide (Atrovent), albuterol (Proventil), glucocorticoid (steroid)
Here's the rationale for this order:
Ipratropium bromide (Atrovent): Ipratropium is an anticholinergic bronchodilator that helps to relax the muscles around the airways, allowing for increased airflow. It is typically recommended to use ipratropium before other bronchodilators to maximize their effectiveness.
Albuterol (Proventil): Albuterol is a short-acting beta-agonist bronchodilator. It works by relaxing the muscles in the airways, leading to improved airflow. Using it after ipratropium further promotes bronchodilation.
Glucocorticoid (steroid): Inhaled glucocorticoids have anti-inflammatory effects and help to reduce airway inflammation. Using the glucocorticoid last allows it to reach the airways and exert its anti-inflammatory effects.
