A patient asks the nurse to define hypersensitivity reaction. The nurse begins by telling the patient that a hypersensitivity reaction is also called:
antagonistic reaction
drug idiosyncracy
synergistic reaction
allergic reaction
The Correct Answer is D
A. Antagonistic reaction:
An antagonistic reaction refers to a response where one substance opposes the action of another substance. In the context of hypersensitivity reactions, this term does not accurately describe the immune system's response to an allergen. Hypersensitivity reactions involve an overreaction of the immune system to a harmless substance, rather than opposing actions between substances. Therefore, choice A is not the correct term to describe hypersensitivity reactions.
B. Drug idiosyncrasy:
Drug idiosyncrasy refers to an unusual or unexpected response to a medication that is not related to the known pharmacological properties of the drug or the patient's characteristics. While idiosyncratic drug reactions can sometimes involve immune-mediated mechanisms, they are not synonymous with hypersensitivity reactions. Hypersensitivity reactions specifically involve the immune system's exaggerated response to an allergen, which may or may not be a medication. Therefore, while drug idiosyncrasy may involve unpredictable reactions, it does not specifically address the immune-mediated nature of hypersensitivity reactions.
C. Synergistic reaction:
A synergistic reaction occurs when the combined effect of two substances is greater than the sum of their individual effects. In the context of hypersensitivity reactions, this term does not accurately describe the immune system's response to an allergen. Hypersensitivity reactions involve an exaggerated response of the immune system to an allergen, rather than a synergistic interaction between substances. Therefore, choice C is not the correct term to describe hypersensitivity reactions.
D. Allergic reaction:
An allergic reaction is the correct term to describe hypersensitivity reactions. Hypersensitivity reactions involve the immune system's exaggerated response to a harmless substance, known as an allergen. This response can manifest in various symptoms, ranging from mild to severe, depending on the individual's sensitivity and the nature of the allergen. Allergic reactions can affect different organ systems and can be triggered by a wide range of substances, including foods, medications, environmental allergens, and insect venom. Therefore, choice D accurately describes hypersensitivity reactions.

Correct Answer is ["A","B","D"]
Explanation
A.Recognizing the role of spirituality in health and healing:
Many CAM therapies acknowledge the importance of spirituality in health and healing. Spiritual well-being is considered an integral aspect of overall health in many CAM modalities. Practices such as meditation, yoga, and mindfulness often incorporate spiritual elements. Therefore, recognizing the role of spirituality in health and healing is a common characteristic of CAM therapies.
B. Focusing on treatment of the person as an individual:
One of the key principles of CAM therapies is treating the individual as a whole, taking into account physical, mental, emotional, and spiritual aspects of health. CAM practitioners often emphasize personalized care tailored to the unique needs and characteristics of each individual. Therefore, focusing on the treatment of the person as an individual is a common characteristic of CAM therapies.
C. Focusing only on physical health:
This statement is incorrect. Unlike conventional Western medicine, which primarily focuses on the physical aspects of health and disease, CAM therapies often take a holistic approach that considers the interconnectedness of the mind, body, and spirit. Therefore, CAM therapies typically address physical, mental, emotional, and spiritual aspects of health, rather than focusing solely on physical health.
D.Promotion of disease prevention, self-care, and self-healing:
Many CAM therapies emphasize the importance of disease prevention, self-care practices, and the body’s innate ability to heal itself. These therapies often encourage individuals to take an active role in maintaining their health and well-being through lifestyle modifications, stress management techniques, dietary changes, and other self-care practices. Therefore, promotion of disease prevention, self-care, and self-healing is a common characteristic of CAM therapies.
Correct Answer is B
Explanation
A. Bacteriostatics are narrow spectrum drugs, and bactericidal drugs are broad spectrum:
This statement is incorrect. The spectrum of activity (narrow vs. broad) of an antibiotic refers to the range of bacterial species that it can target, not whether it is bacteriostatic or bactericidal.
B. Bacteriostatic drugs inhibit bacterial growth, and bactericidal drugs actually kill bacteria:
This statement is correct. Bacteriostatic drugs work by inhibiting the growth and reproduction of bacteria without directly killing them, whereas bactericidal drugs directly kill bacteria.
C. Bacteriostatics work by inhibiting protein synthesis, and bactericidal drugs work by inhibiting nucleic acid synthesis:
This statement is incorrect. Both bacteriostatic and bactericidal drugs can target various bacterial cellular processes, including protein synthesis, nucleic acid synthesis, cell wall synthesis, and others. The mechanism of action is not a definitive factor in distinguishing between bacteriostatic and bactericidal drugs.
D. Bacteriostatic drugs actually kill bacteria, and bactericidal drugs inhibit bacterial growth:
This statement is incorrect. It contradicts the established definitions of bacteriostatic and bactericidal drugs. Bacteriostatic drugs inhibit bacterial growth without killing the bacteria, while bactericidal drugs directly kill bacteria.
