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
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
Sucralfate is a medication used to treat and prevent ulcers. It works by forming a protective barrier over the ulcer, allowing it to heal. Therefore, the statement “This medication will help prevent future ulcers” is correct.
Choice B rationale
Sucralfate should be taken on an empty stomach, not with food. This is because food can interfere with the medication’s ability to form a protective barrier over the ulcer.
Choice C rationale
Constipation is a common side effect of sucralfate. Therefore, the statement “This medication can cause constipation” is correct.
Choice D rationale
Coughing up blood can be a sign of a serious condition, such as a bleeding ulcer. If a patient taking sucralfate starts coughing up blood, they should definitely call their doctor.
Correct Answer is C
Explanation
Choice A rationale
Administering ondansetron when the client feels nauseous or vomits is not the most effective use of the medication. The goal is to prevent nausea and vomiting from occurring in the first place.
Choice B rationale
Administering ondansetron immediately after chemotherapy is complete may not provide the most effective prevention of nausea and vomiting. The medication needs time to work and should ideally be administered before chemotherapy begins.
Choice C rationale
The optimal time to administer ondansetron is 30 minutes prior to starting chemotherapy. This allows the medication to start working before the chemotherapy drugs that cause nausea and vomiting are administered.
Choice D rationale
While it’s important to respond to a client’s requests, waiting until the client requests the ondansetron may not prevent the onset of nausea and vomiting. It’s more effective to administer the medication proactively.
