After teaching a group of students about tetracyclines, the instructor determines that the teaching was successful when the students identify which of the following as a true statement?

Tetracyclines are narrow-spectrum antibiotics.

Tetracyclines may cause permanent discoloration of the teeth in children.

Tetracyclines cannot be used when penicillins are contraindicated.

Tetracyclines are not contraindicated in children younger than 9 years.

Tetracyclines are used to treat influenza.

Answer and Explanation

The Correct Answer is B

Choice A rationale:

Tetracyclines are not narrow-spectrum antibiotics. They are broad-spectrum antibiotics. Tetracyclines are effective against a wide range of bacteria, including both Gram-positive and Gram-negative organisms. This is important in treating various infections, but it also means they can disrupt the normal flora of the gut, potentially leading to issues like antibiotic-associated diarrhea.

Choice B rationale:

Tetracyclines may cause permanent discoloration of the teeth in children. This is a well-known adverse effect of tetracycline antibiotics. It primarily occurs in children under the age of 8, whose teeth are still developing. Tetracyclines can bind to calcium ions in teeth, leading to a yellow or grayish discoloration. This is why tetracyclines are generally avoided in children and pregnant women.

Choice C rationale:

Tetracyclines can be used when penicillins are contraindicated. Tetracyclines and penicillins are different classes of antibiotics, and being contraindicated for one does not necessarily mean the other is also contraindicated. Tetracyclines can be an alternative for patients who cannot tolerate penicillins due to allergies or other contraindications.

Choice D rationale:

Tetracyclines are not contraindicated in children younger than 9 years. This statement is not accurate. Tetracyclines are contraindicated in children under the age of 8 due to the risk of tooth discoloration. After the age of 8, tetracyclines can be used in children, but caution is still required.

Choice E rationale:

Tetracyclines are not used to treat influenza. Influenza is caused by viruses, not bacteria, and tetracyclines are antibiotics that target bacteria. Influenza is typically treated with antiviral medications, such as oseltamivir (Tamiflu).

Correct Answer is A

Explanation

Choice A rationale:

Emetics are medications that induce vomiting and are used in cases of drug overdose, ingestion of toxic substances, or other situations where rapid removal of the ingested substance is necessary. However, it is crucial that the client's mental status is intact and they can cooperate and understand the need to induce vomiting. If a client is unconscious or unable to protect their airway, inducing vomiting can lead to aspiration and further complications.

Choice B rationale:

Clients with existing severe hypertension should not be administered emetics, as the act of inducing vomiting can lead to a sudden increase in blood pressure, potentially causing adverse cardiovascular events.

Choice C rationale:

Clients with a medical history of convulsions (seizures) should not be given emetics. Inducing vomiting may lead to a convulsive episode, which can be harmful and increase the risk of aspiration.

Choice D rationale:

Clients with an existing condition of hemorrhagic diathesis (a tendency to bleed excessively) should not be administered emetics. Inducing vomiting can cause mucosal damage and bleeding in the gastrointestinal tract, further exacerbating the client's condition.

A. Sedation. B. Bruising. C. Altered taste. D. Constipation.

Correct Answer is B

Explanation

Choice A rationale:

Sedation is not a common adverse reaction to antiretroviral therapy. Antiretroviral medications are primarily used to treat HIV and do not typically cause sedation.

Choice B rationale:

Bruising is a potential adverse reaction to antiretroviral therapy. Some antiretroviral medications can cause blood-related side effects, such as decreased platelet count, which can result in easy bruising and bleeding. It's important for the nurse to include this in the teaching plan to ensure the client is aware of this potential side effect.

Choice C rationale:

Altered taste is not a common adverse reaction to antiretroviral therapy. While some medications can cause taste disturbances, this is not a typical side effect of antiretroviral drugs.

Choice D rationale:

Constipation is not a common adverse reaction to antiretroviral therapy. Antiretroviral medications primarily target the HIV virus and do not typically cause gastrointestinal issues like constipation.
