The nurse is teaching a client about possible adverse reactions that can occur with tetracyclines.
The nurse determines that the teaching was successful when the client identifies which of the following?

Choice A rationale:

Frequency of urination increasing is not typically associated with iron supplements. Iron supplements are more likely to cause constipation or darkening of stools due to increased iron content in the stool.

Choice B rationale:

Soreness of the throat is not a common side effect of iron supplements. While iron supplements can sometimes cause gastrointestinal discomfort, sore throat is not a usual manifestation.

Choice C rationale:

Itching of the throat might occur when taking iron supplements. Iron can irritate the gastrointestinal tract, and this irritation may extend to the throat, causing mild itching or discomfort.

Choice D rationale:

The color of stools becoming darker is a common side effect of iron supplements. Iron can darken stools and make them appear black, which is known as "black, tarry stools.”. This is due to the unabsorbed iron in the gastrointestinal tract.

Choice A rationale:

Naturally acquired active immunity occurs when an individual is exposed to a disease-causing agent for the first time and develops immunity through their immune response. In this case, the client is exposed to chickenpox for the first time, and the immune system will produce antibodies to provide future protection.

Choice B rationale:

Administration of a vaccine (varicella vaccine) is an example of artificially acquired active immunity. The client's immune system responds to the weakened or inactivated pathogen in the vaccine to produce immunity. This choice does not represent naturally acquired immunity.

Choice C rationale:

Similar to choice B, administration of the influenza vaccine is an example of artificially acquired active immunity. The vaccine contains inactivated influenza virus components, prompting the individual's immune system to develop immunity.

Choice D rationale:

Administration of the rubella vaccine is another example of artificially acquired active immunity. The vaccine stimulates the immune system to produce antibodies against rubella, but this is not an example of naturally acquired immunity.
