A patient started propylthiouracil therapy a month ago and is here for a follow-up lab test (results shown below). Which lab value should the nurse be most concerned about?

T3 and T4

White blood cell count

Hemoglobin and Hematocrit

Platelet count

Answer and Explanation

The Correct Answer is B

Choice A rationale
T3 and T4 are thyroid hormones. While it’s important to monitor these levels in a patient on propylthiouracil therapy, they are not the most concerning lab value.
Choice B rationale
The white blood cell count should be the nurse’s primary concern. Propylthiouracil can cause agranulocytosis, a serious condition characterized by a decrease in the number of white blood cells, which can lead to infection.
Choice C rationale
Hemoglobin and hematocrit levels are important to monitor, but they are not the most concerning lab value in this context.
Choice D rationale
While it’s important to monitor platelet count in a patient on propylthiouracil therapy, it’s not the most concerning lab value.

Correct Answer is B

Explanation

Choice A rationale
While staying hydrated is generally good advice, drinking at least 2 liters of water a day is not specifically related to preventing antibiotic resistance.
Choice B rationale
Taking antibiotics on-time around the clock is crucial for maintaining therapeutic levels of the medication in the body. This helps to effectively kill the bacteria and prevent them from developing resistance.
Choice C rationale
Eating a serving of yogurt every day can help maintain gut health during antibiotic treatment, but it does not directly prevent antibiotic resistance.
Choice D rationale
Stopping antibiotics when symptoms resolve can actually contribute to antibiotic resistance. Even if symptoms have improved, bacteria may still be present. Stopping treatment early gives these bacteria a chance to survive and develop resistance.

A. You can take antacids with levofloxacin to reduce gastrointestinal discomfort. B. Levofloxacin should be taken on an empty stomach to enhance absorption. C. You can take nonsteroidal anti-inflammatory drugs (NSAIDs) for arthritis pain. D. You should monitor your blood glucose levels more frequently while on levofloxacin.

Correct Answer is D

Explanation

Choice A rationale
While antacids can help reduce gastrointestinal discomfort, they do not interact specifically with levofloxacin or affect blood glucose levels.
Choice B rationale
Taking levofloxacin on an empty stomach can enhance absorption, but it does not affect blood glucose levels.
Choice C rationale
Nonsteroidal anti-inflammatory drugs (NSAIDs) can be taken for arthritis pain, but they do not interact specifically with levofloxacin or affect blood glucose levels.
Choice D rationale
Levofloxacin can cause changes in blood glucose levels, so patients with diabetes who are on oral hypoglycemic medication should monitor their blood glucose levels more frequently while on levofloxacin.
