A nurse in a provider's clinic is assessing a client Who has cancer and a prescription for methotrexate PO. Which of the following actions should the nurse take when the client reports bleeding gums?

The correct answer is B: Check the value of the client's current platelet count. Bleeding gums can be a sign of thrombocytopenia, a side effect of methotrexate that causes a decrease in platelet count. By checking the platelet count, the nurse can assess if the bleeding gums are related to this condition. In contrast, choice A (using an electric toothbrush) does not address the underlying cause of the bleeding gums. Choice C (seeing a dentist) may be necessary but does not address the potential hematological issue. Choice D (explaining it as an expected adverse effect) is incorrect as it does not provide an immediate clinical assessment.
