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 C
Explanation
A. “This medication is a leading cause of bronchospasm.”
Glucocorticoid inhalers are not a leading cause of bronchospasm. In fact, they are often prescribed to reduce inflammation and prevent bronchospasm in conditions like asthma and chronic obstructive pulmonary disease (COPD).
B. “This medication will cause you to become fatigued.”
Fatigue is not a common side effect of inhaled glucocorticoids. Systemic effects are more likely with oral or intravenous administration, whereas inhaled forms are designed to have localized effects.
C. “You must gargle and rinse your mouth immediately after each use of this medication.”
Inhaled glucocorticoids can sometimes lead to local side effects, such as oral candidiasis (thrush) or hoarseness. Gargling and rinsing the mouth after using the inhaler can help minimize these side effects by reducing the risk of fungal overgrowth in the mouth and throat.
D. “This medication may cause you to feel anxious.”
Anxiety is not a common side effect of inhaled glucocorticoids. Again, systemic effects are more associated with other routes of administration. The use of inhaled glucocorticoids is generally well-tolerated when used as directed.
Correct Answer is C
Explanation
A. "My provider will prescribe prophylactic antibiotics."
While antibiotics may be prescribed if there is a bacterial infection or exacerbation, they are not typically used prophylactically in all cases of mild emphysema.
B. "My condition is reversible with proper medications."
Emphysema is a chronic and typically irreversible condition. While medications can help manage symptoms and improve quality of life, they do not generally reverse the damage caused by emphysema.
C. "I should use albuterol (Proventil) when my symptoms worsen."
Albuterol (Proventil) is a short-acting beta-agonist bronchodilator, and it is commonly used as a rescue inhaler to provide quick relief of symptoms such as shortness of breath and wheezing in patients with conditions like emphysema. Using albuterol as needed during symptom exacerbations aligns with appropriate management of mild emphysema.
D. "I will need to take oral prednisone on a daily basis."
Daily use of oral prednisone is not a standard treatment for mild emphysema. Prednisone is a corticosteroid that may be used in certain situations, such as during exacerbations, but its long-term use carries potential risks and is generally avoided unless necessary.
