Which medication is considered a “rescue inhaler”?
Glucocorticoid
Mast cell stabilizer
Mucolytic agent
Short-acting beta 2 agonist
The Correct Answer is D
A. Glucocorticoid
Glucocorticoids are anti-inflammatory medications commonly used as long-term control medications in asthma management. They are not typically considered rescue inhalers. They work gradually over time to reduce inflammation and are not suitable for immediate relief during an acute asthma attack.
B. Mast cell stabilizer
Mast cell stabilizers are anti-inflammatory medications that work by preventing the release of inflammatory substances from mast cells. They are used as maintenance therapy to prevent asthma symptoms but are not rescue inhalers. They do not provide quick relief during acute episodes.
C. Mucolytic agent
Mucolytic agents are medications that help thin and loosen mucus in the airways. While they may be used to improve respiratory symptoms, they are not considered rescue inhalers. They do not provide rapid bronchodilation and are typically used for different purposes, such as addressing mucus production and clearance.
D. Short-acting beta 2 agonist
This is the correct answer. Short-acting beta 2 agonists (SABAs) are bronchodilators that provide quick relief during acute bronchoconstriction. They act by relaxing the smooth muscles in the airways, allowing for rapid dilation and improved airflow. SABAs are commonly used as rescue inhalers to alleviate symptoms during asthma attacks or sudden exacerbations.

Correct Answer is D
Explanation
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. "The client’s degree of nausea."
The client's degree of nausea is a side effect of chemotherapy, but it is not a major obstacle to successful chemotherapy in the broader sense. Nausea can often be managed with antiemetic medications, and it is generally considered a manageable aspect of chemotherapy care.
B. "The patient’s reluctance about the doses administered."
Patient compliance and acceptance of the prescribed treatment are important factors in the success of chemotherapy. However, while patient reluctance can be a challenge, it is not considered a major obstacle to chemotherapy as there are strategies and interventions to address issues related to patient understanding, fears, or concerns.
C. "The toxicity of anticancer drugs to normal tissues."
This is the correct answer. The toxicity of anticancer drugs to normal tissues is a major obstacle in chemotherapy. While the drugs aim to kill rapidly dividing cancer cells, they can also affect healthy cells, leading to side effects and complications. Striking a balance between effective cancer treatment and minimizing harm to normal tissues is a key challenge in chemotherapy.
D. "The difficulty of maintaining venous access."
Maintaining venous access can be a logistical challenge in chemotherapy, but it is not considered a major obstacle to successful treatment. While it is important for delivering chemotherapy drugs, there are various methods and technologies to address issues related to venous access, such as the use of central venous catheters or ports.
