"My doctor said I have an autoimmune disease. What does that mean?" asks a client. How should the nurse respond?
"You have developed urticaria in response to something in your environment."
"Your immune system is creating antibodies that are destroying your own cells."
"Your immune system is not able to create antibodies to help you fight infection."
"You have developed an infection that is destroying your immune cells."
The Correct Answer is B
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 A
Explanation
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. "Bactericidal and bacteriostatic are used interchangeably."
Explanation: This statement is incorrect. Bactericidal and bacteriostatic are two distinct categories of antibiotics with different mechanisms of action.
B. "Bactericidal drugs are directly lethal to bacteria, and bacteriostatic drugs work to slow bacterial growth but do not cause cell death."
Explanation: This statement is correct. Bactericidal drugs kill bacteria directly, leading to their death, while bacteriostatic drugs inhibit bacterial growth without causing immediate cell death.
C. "Bacteriostatic drugs are directly lethal to bacteria, and bactericidal drugs work to slow bacterial growth but do not cause cell death."
Explanation: This statement is incorrect. It is the opposite of the correct explanation. Bacteriostatic drugs do not directly kill bacteria, and bactericidal drugs do cause bacterial death.
D. "A bactericidal drug can cause death to the host, whereas a bacteriostatic drug only affects bacteria."
Explanation: This statement is not entirely accurate. While some bactericidal drugs can be more toxic to the host, it depends on the specific drug and its dosage. Bacteriostatic drugs, on the other hand, generally do not directly harm the host. The primary distinction between the two categories is their impact on bacterial growth and survival.
