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 B

Explanation

A. Difficulty swallowing. B. Nausea. C. Muscle laxity. D. Shuffling gait.

Correct Answer is A

Explanation

Choice B rationale:

Nausea is a common side effect of metoclopramide, and while it is important to monitor, it is not a symptom that the client should specifically report to the primary healthcare provider unless it becomes severe or persistent.

Choice C rationale:

Muscle laxity and shuffling gait (Choices C and D) are potential side effects of other medications, such as antipsychotic drugs, but they are not typically associated with metoclopramide. Therefore, these are not the symptoms the client should report. Difficulty swallowing (Choice A) is a concerning side effect of metoclopramide and should be reported to the healthcare provider immediately. It can be a sign of a serious condition called tardive dyskinesia, which is a potentially irreversible side effect of the medication. Early recognition and discontinuation of metoclopramide are essential to prevent further complications.
