After teaching a group of nursing students about antiprotozoal drugs, the instructor determines that the teaching was successful when the group identifies which of the following as an indication for use?

Choice A rationale:

Isoniazid Isoniazid is one of the first-line drugs used in the initial treatment phase of tuberculosis (TB). It is a key component of the standard regimen for TB treatment. Isoniazid is highly effective against Mycobacterium tuberculosis, the bacterium responsible for TB, and it plays a critical role in the initial phase of treatment to rapidly reduce the bacterial load.

Choice B rationale:

Ciprofloxacin Ciprofloxacin is not a first-line drug for the treatment of tuberculosis. While it has antibacterial properties, it is not considered one of the primary agents for TB treatment. It is more commonly used to treat other types of bacterial infections, such as urinary tract infections.

Choice C rationale:

Gentamycin Gentamycin is not typically used as a first-line treatment for TB. It is reserved for specific situations, such as drug-resistant TB cases, and is not part of the standard initial treatment regimen for TB.

Choice D rationale:

Clindamycin Clindamycin is not a first-line drug for the treatment of tuberculosis. It is primarily used to treat anaerobic bacterial infections and is not a standard part of TB treatment protocols.

Choice A rationale:

Fever is a common side effect of the influenza vaccine (Fluzone). It's not usually a severe adverse reaction and is typically mild and short-lived. Patients should be informed about this potential side effect so they are aware and can take appropriate measures, such as taking antipyretic medications if needed.

Choice B rationale:

Hypotension is not a common adverse reaction to the influenza vaccine. While vaccines can sometimes cause allergic reactions, leading to symptoms like hypotension, this is very rare. Warning about this potential side effect would not be a priority.

Choice C rationale:

Sedation is not a common adverse reaction to the influenza vaccine. In general, the influenza vaccine is not associated with sedation. This side effect is more likely to be associated with medications or treatments other than vaccines.

Choice D rationale:

Constipation is not a common side effect of the influenza vaccine. Gastrointestinal symptoms like constipation are not typically associated with the influenza vaccine. It's important to focus on informing patients about potential side effects that are more likely to occur.
