A nurse is caring for a client who was exposed to anthrax.
Which of the following antibiotics should the nurse plan to administer?

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.

Choice A rationale:

Liothyronine (Cytomel) is a type of thyroid hormone used to treat an underactive thyroid (hypothyroidism). It replaces or provides more thyroid hormone, which is normally produced by the thyroid gland. However, it is not typically used to treat hyperthyroidism.

Choice B rationale:

Liotrix (Thyrolar) is a combination of two thyroid hormones, levothyroxine (T4) and liothyronine (T3), used to treat hypothyroidism, and to prevent and treat goiter. Similar to Liothyronine, it is not typically used to treat hyperthyroidism. Choice C rationale:

Levothyroxine (Synthroid) is used to treat an underactive thyroid (hypothyroidism). It replaces or provides more thyroid hormone, which is normally produced by the thyroid gland. Low thyroid hormone levels can occur naturally or when the thyroid gland is injured by radiation/medications or removed by surgery. Having enough thyroid hormone helps maintain normal mental and physical activity. In children, having enough thyroid hormone helps them grow and learn normally.

Choice D rationale:

Propylthiouracil (Propacil) is an antithyroid agent used in the treatment of hyperthyroidism. It works by decreasing the amount of thyroid hormone produced by the thyroid gland. This helps to prevent the excessive heat, rapid heart rate, and nervousness caused by too much thyroid hormone in the body.
