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 C

Explanation

Choice A rationale
Monitoring blood pressure for hypertension during the infusion is important, but it is not the primary measure to reduce complications with vancomycin administration3.
Choice B rationale
Restricting fluids during vancomycin therapy is not recommended. Adequate hydration is important when receiving vancomycin to prevent kidney damage3.
Choice C rationale
Infusing the drug over at least 1 hour is the most crucial measure to reduce complications that may occur with vancomycin administration. This is to prevent “red man syndrome,” a reaction that can cause flushing, rash, and hypotension3.
Choice D rationale
Discontinuing the drug immediately if red man syndrome occurs is not the primary measure. The infusion can often be slowed down or temporarily stopped to manage this reaction3.

A. Drink at least 2 liters of water a day B. Take antibiotics on-time around the clock C. Eat a serving of yogurt every day D. Stop antibiotics when symptoms resolve.

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.
