The nurse who is working in a pediatric unit administers tetracycline [Sumycin] to a preschool-age child. What is a potential adverse effect of the medication for this child?
Discoloration of teeth
Anabolic change
Cartilage damage
Suppression of growth
The Correct Answer is A
A. Discoloration of teeth: Tetracycline antibiotics can bind with calcium ions in teeth, leading to the development of yellow-gray-brown stains. This effect is particularly significant in developing teeth in children below the age of 8 and can result in permanent discoloration.
B. Anabolic change: This term doesn't specifically relate to the side effects of tetracycline. "Anabolic" generally refers to processes in the body that build up complex molecules from simpler ones. There's no direct connection between tetracycline and anabolic changes.
C. Cartilage damage: Tetracyclines, especially in high doses or with prolonged use, have been associated with potential adverse effects on cartilage. This is more relevant in individuals whose bones and cartilage are still growing, such as children. It can interfere with skeletal development.
D. Suppression of growth: Long-term use of tetracycline in children can interfere with bone growth and development. It can suppress the growth of bones and affect overall height. This is a significant concern when considering the use of tetracycline in pediatric patients.

Correct Answer is B
Explanation
A. "You have developed urticaria in response to something in your environment."
This statement is incorrect. Urticaria refers to hives, a skin rash usually caused by an allergic reaction, infection, or stress. It's not necessarily indicative of an autoimmune disease.
B. "Your immune system is creating antibodies that are destroying your own cells."
This statement is correct. Autoimmune diseases involve the immune system mistakenly attacking the body's own cells and tissues, leading to various health issues.
C. "Your immune system is not able to create antibodies to help you fight infection."
This statement is incorrect. In autoimmune diseases, the immune system is overactive, producing antibodies that target the body's own cells, not that it can't create antibodies.
D. "You have developed an infection that is destroying your immune cells."
This statement is incorrect. Infections don't typically destroy immune cells; instead, infections often stimulate the immune system to respond and fight against invading pathogens.
Correct Answer is D
Explanation
A. Neutrophils: Neutrophils are a type of white blood cell that plays a key role in the immune system's response to infections, particularly bacterial infections. They are not primarily involved in eliminating cancer cells.
B. Eosinophils: Eosinophils are another type of white blood cell. They are important in the immune response to parasites and are also involved in allergic reactions. While they have a role in the immune system, they are not the primary cells involved in eliminating cancer cells.
C. Platelets: Platelets, also known as thrombocytes, are not cells but rather small cell fragments. They are essential for blood clotting and do not directly participate in the immune response against cancer cells.
D. Macrophages: Macrophages are a type of white blood cell that are involved in the immune system's defense against cancer. They are phagocytes, which means they engulf and digest cellular debris, foreign substances, and cancer cells. Macrophages play a crucial role in the body's immune surveillance and response against cancer.
