Which of the following medications is typically prescribed for the treatment of hyperthyroidism?
 

Choice A rationale:

Double vision is not a common side effect of quinolones. Quinolones are a type of antibiotic that are used to kill or inhibit the growth of bacteria. While they can have side effects, double vision is not typically one of them.

Choice B rationale:

Tendonitis and tendon rupture are known adverse effects of quinolones. These antibiotics can very rarely cause long-lasting, disabling, and potentially irreversible side effects, sometimes affecting multiple systems, organ classes, and senses. One of these side effects is damage to the tendons, which can manifest as tendonitis (inflammation of the tendon) or even tendon rupture. This is particularly a concern for people older than 60 years and for those with renal impairment or solid-organ transplants because they are at a higher risk of tendon injury.

Choice C rationale:

Neuralgia, or nerve pain, is not a common side effect of quinolones. While these antibiotics can affect the nervous system and cause side effects such as peripheral neuropathy and central nervous system effects, neuralgia is not typically reported.

Choice D rationale:

Hypotension, or low blood pressure, is not typically associated with the use of quinolones. These antibiotics can have various side effects, but a significant drop in blood pressure is not commonly reported.

Choice A rationale:

Administering the antibiotic dose before obtaining the cultures could potentially affect the results of the cultures. Antibiotics are designed to kill or inhibit the growth of bacteria, so administering them before obtaining the cultures could lead to false negatives. This could lead to incorrect or delayed diagnosis and treatment.

Choice B rationale:

While obtaining the urine culture before administering the antibiotic dose is a good step, it should not be done before obtaining the blood culture. Blood cultures are usually obtained before urine cultures because they can help identify bacteria or fungi in the blood. This can be crucial in diagnosing conditions like sepsis. Furthermore, administering the antibiotic dose before obtaining the blood culture could affect the results of the culture.

Choice C rationale:

Obtaining the blood culture before administering the antibiotic dose is a good step, but the urine culture should also be obtained before the antibiotic dose is administered. Administering the antibiotic dose before obtaining all necessary cultures could affect the results of the cultures and lead to incorrect or delayed diagnosis and treatment.

Choice D rationale:

This is the correct sequence of actions. The nurse should first obtain both blood and urine cultures before administering the antibiotic dose. This is because the antibiotic could potentially kill or inhibit the growth of bacteria, which could affect the results of the cultures. By obtaining the cultures first, the healthcare team can ensure they are getting accurate results that have not been influenced by the antibiotics. This can lead to a more accurate diagnosis and more effective treatment plan.
