A client with immune thrombocytopenic purpura (ITP) will begin treatment with romiplostim (Nplate) to be administered by subcutaneous injection in the provider's office once per week. Which statement should the nurse plan to include when educating the client about this medication?
This medication increases the production of plasma enzyme ADAMTS-13.
This medication prevents platelets from being destroyed in the spleen.
This medication prevents platelets from binding with heparin.
This medication stimulates the bone marrow to increase platelet production.
The Correct Answer is D
A. Romiplostim does not increase the production of ADAMTS-13; it is used to increase platelet counts.
B. Romiplostim does not prevent platelet destruction in the spleen; it works by stimulating platelet production.
C. Romiplostim does not prevent platelets from binding with heparin; it is not used for heparin-induced thrombocytopenia.
D. Romiplostim is a thrombopoietin receptor agonist that stimulates the bone marrow to increase platelet production, which is its primary mechanism of action in treating ITP.

D. Stable angina is related to chest pain and does not have specific ECG findings such as extra P-waves.
Correct Answer is D
Explanation
A. NSTEMI would present with elevated troponin levels indicating myocardial injury, which is not the case here.
B. Stable angina occurs predictably with exertion and is relieved by rest or nitroglycerin.
C. STEMI is characterized by ST-elevation on the ECG and elevated troponin levels, indicating significant myocardial injury.
D. Unstable angina presents with chest pain that occurs at rest or with minimal exertion and is not predictable. The presence of T-wave inversion and normal troponin levels is consistent with this diagnosis.
