A nurse is caring for a client who has been taking epoetin alfa for 3 months.
Which of the following laboratory tests should the nurse monitor to determine the effectiveness of the medication?
AST.
Troponin.
T4.
Hgb.
The Correct Answer is D
Choice A rationale:
AST (Aspartate Aminotransferase) is a liver enzyme and its levels are used to assess liver function, not the effectiveness of epoetin alfa.
Choice B rationale:
Troponin is a cardiac marker used to diagnose heart attacks. It has no relation with the effectiveness of epoetin alfa.
Choice C rationale:
T4 (Thyroxine) is a thyroid hormone. Its levels indicate thyroid function, not the effectiveness of epoetin alfa.
Choice D rationale:
Hgb (Hemoglobin) levels are used to assess the effectiveness of epoetin alfa. Epoetin alfa is a medication that stimulates the production of red blood cells, thereby increasing hemoglobin levels in the blood. Normal hemoglobin levels are 13.5 to 17.5 g/dL in men and 12.0 to 15.5 g/dL in women.

Correct Answer is D
Explanation
Choice A rationale:
Fexofenadine can be taken with or without food, and there are no specific interactions with magnesium hydroxide. However, it’s always important to consult a healthcare provider before combining medications.
Choice B rationale:
While staying hydrated is generally good advice, there’s no specific requirement to drink up to one liter of fluid per day while taking fexofenadine.
Choice C rationale:
Fexofenadine should not be taken with fruit juices such as orange juice because they can decrease the absorption of the medication, making it less effective.
Choice D rationale:
Fexofenadine can cause side effects such as dizziness or drowsiness in some people. Therefore, it’s important to avoid driving or operating heavy machinery until you know how this medication affects you.
