Which adverse effect unique to vancomycin is caused by histamine release?
Discoloration of body fluids
Ototoxicity
Red-man syndrome
Nephrotoxicity
The Correct Answer is C
A. Discoloration of body fluids:
Vancomycin can cause discoloration of body fluids, particularly urine, resulting in a brownish discoloration. However, this is not caused by histamine release.
B. Ototoxicity:
Ototoxicity refers to damage to the inner ear structures leading to hearing loss or balance problems. While vancomycin can cause ototoxicity, it is not specifically associated with histamine release.
C. Red-man syndrome
Red-man syndrome, also known as red-neck syndrome or red-person syndrome, is a hypersensitivity reaction characterized by flushing of the skin, particularly the upper body and face, resembling a "red man." This reaction is typically associated with the rapid infusion of vancomycin and is caused by the release of histamine from mast cells and basophils. It is not an allergic reaction but rather a non-immunologic response to vancomycin.
D. Nephrotoxicity:
Nephrotoxicity refers to kidney damage caused by certain medications or toxins. While vancomycin can cause nephrotoxicity, it is not specifically associated with histamine release.

Explanation
A. Prayer:
Prayer is a spiritual practice that involves communicating with a higher power or deity. It has been used for centuries across various cultures and religions as a means of seeking guidance, comfort, and healing. While the direct physical effects of prayer on the body may not be well understood, many people find that prayer can provide emotional support, reduce stress, and promote a sense of well-being. Additionally, some research suggests that prayer may have positive effects on mental health and overall quality of life.
B. Meditation:
Meditation is a practice that involves focusing the mind and cultivating awareness, often through techniques such as mindfulness, breathing exercises, or guided imagery. It has been practiced for centuries in Eastern traditions such as Buddhism and Hinduism, as well as in other cultures around the world. Meditation is known for its ability to promote relaxation, reduce stress, and improve mental clarity. It has also been associated with numerous physical health benefits, including lower blood pressure, improved immune function, and better sleep.
C. Ointments with a steroid base:
Ointments with a steroid base are not typically considered CAM therapies. Instead, they are a form of conventional medical treatment commonly used to reduce inflammation and treat various skin conditions. These ointments contain corticosteroids, which are synthetic drugs that mimic the effects of hormones produced by the adrenal glands. They work by suppressing the body's immune response and reducing inflammation in the affected area. While steroid-based ointments can be effective for treating certain skin conditions, they are not part of traditional CAM practices.
D. Massage:
Massage therapy involves manipulating the body's soft tissues, including muscles, tendons, and ligaments, to promote relaxation, relieve muscle tension, and improve circulation. It has been practiced for centuries in cultures around the world and is commonly used to alleviate stress, reduce pain, and enhance overall well-being. Massage therapy encompasses various techniques, such as Swedish massage, deep tissue massage, and aromatherapy massage, each with its own benefits and applications. Research has shown that massage therapy can have numerous physical and mental health benefits, including reduced anxiety, improved mood, and enhanced immune function.
Correct Answer is D
Explanation
A. Not affected:
This choice suggests that taking ciprofloxacin with antacids does not alter its absorption. However, this is not correct. When ciprofloxacin is taken with antacids containing certain ions (such as aluminum, magnesium, or calcium), the absorption of ciprofloxacin can indeed be affected due to the formation of insoluble complexes, leading to decreased absorption.
B. Delayed:
This choice implies that taking ciprofloxacin with antacids delays its absorption. While it's true that the interaction between ciprofloxacin and certain antacids can alter absorption, the main effect is not typically a delay in absorption but rather a decrease due to the formation of insoluble complexes. Therefore, while "delayed" may somewhat describe the effect, it doesn't fully capture the nature of the interaction.
C. Increased:
This choice suggests that taking ciprofloxacin with antacids increases its absorption. However, this is not accurate. Antacids containing aluminum, magnesium, or calcium can interfere with the absorption of ciprofloxacin by forming insoluble complexes with the drug, leading to decreased absorption rather than an increase.
D. Decreased:
This choice correctly identifies the effect of taking ciprofloxacin with antacids. When ciprofloxacin is taken concurrently with antacids containing aluminum, magnesium, or calcium, the absorption of ciprofloxacin is decreased. The ions in the antacids bind with ciprofloxacin in the gastrointestinal tract, forming insoluble complexes that are poorly absorbed, thereby reducing the effectiveness of the antibiotic.
