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

Answer and Explanation

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","D"]

Explanation

A. Hypertension: Anaphylaxis often leads to a rapid drop in blood pressure (hypotension) rather than hypertension. Hypotension is a more common symptom because of the severe vasodilation that occurs during anaphylactic reactions.

B. Angioedema: Yes, angioedema is a common clinical manifestation of anaphylaxis. Angioedema involves swelling of the deeper layers of the skin, often around the eyes and lips. It can also affect the throat, which can be life-threatening due to airway obstruction.

C. Petechiae: Petechiae are small red or purple spots that appear on the skin and are caused by bleeding into the skin's tissues. They are not a typical manifestation of anaphylaxis.

D. Bronchospasm: Yes, bronchospasm is a hallmark clinical manifestation of anaphylaxis. It involves the sudden constriction of the airways, leading to difficulty in breathing and wheezing.

A. Bactericidal and bacteriostatic are used interchangeably. B. Bactericidal drugs are directly lethal to bacteria, and bacteriostatic drugs work to slow bacterial growth but do not cause cell death. C. Bacteriostatic drugs are directly lethal to bacteria, and bactericidal drugs work to slow bacterial growth but do not cause cell death. D. A bactericidal drug can cause death to the host, whereas a bacteriostatic drug only affects bacteria.

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.
