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 A
Explanation
A. IgG: Immunoglobulin G (IgG) is the most abundant antibody in the bloodstream and represents about 75% of all the antibodies in the body. It provides long-term immunity because it can persist in the bloodstream for a long time. IgG antibodies are involved in secondary immune responses and are capable of crossing the placenta, providing passive immunity to newborns.
B. IgE: Immunoglobulin E (IgE) is associated mainly with allergic reactions. When the body is exposed to an allergen, it triggers the release of IgE, leading to the symptoms of an allergic response, such as sneezing or itching.
C. IgM: Immunoglobulin M (IgM) is the largest antibody and is usually the first antibody produced during an initial exposure to an antigen. It is particularly effective at agglutination (clumping together) of pathogens.
D. IgA: Immunoglobulin A (IgA) is found in high concentrations in mucous membranes, particularly those lining the respiratory passages and gastrointestinal tract. It provides localized defense against pathogens. IgA antibodies are also found in saliva, tears, and breast milk, providing immunity to infants.
Correct Answer is D
Explanation
A. "The antibiotic I have been taking doesn't work as well as it used to."
This statement shows awareness of decreased effectiveness, which can occur due to drug resistance. Bacteria can become resistant to antibiotics, leading to reduced efficacy of the medication over time.
B. "The bacteria in my body have become resilient."
This statement correctly attributes resistance to the bacteria. Resilience in this context means that bacteria have developed mechanisms to survive the effects of antibiotics, making the treatment less effective.
C. "Over time, an organism that had once been highly sensitive to an antibiotic may become less susceptible, or it may lose drug sensitivity entirely."
This statement accurately describes the concept of drug resistance. Bacteria can lose sensitivity to antibiotics, rendering the drugs ineffective against them.
D. "My body has become resistant to the antibiotic."
This statement is incorrect. It's the bacteria that develop resistance, not the patient's body. Patients don't become resistant to antibiotics; instead, bacteria evolve and adapt, making the drugs less effective against them.
