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:
Two loose stools in the past 24 hours could be a symptom of Clostridioides difficile infection, but it’s not necessarily a priority finding. The infection can cause diarrhea, but it’s not life-threatening.
Choice B rationale:
A WBC count of 11,000/mm³ is slightly elevated, indicating a possible infection. However, it’s not necessarily a priority finding as it’s not significantly high.
Choice C rationale:
A heart rate of 104/min is slightly elevated, indicating possible stress or anxiety. However, it’s not necessarily a priority finding as it’s not significantly high.
Choice D rationale:
Creatinine level of 3.1 mg/dL is significantly high, indicating possible kidney damage, which can be a side effect of vancomycin treatment. This should be reported to the provider immediately.
Correct Answer is C
Explanation
Choice A rationale:
Hanging the antibiotic medication bag above the level of the primary infusion is an important step in administering an antibiotic via intermittent IV bolus. However, it is not the first step. The medication bag is usually hung higher to allow the antibiotic to infuse by gravity once it’s connected.
Choice B rationale:
Wiping the connection port of the primary IV tubing with an antiseptic swab is a crucial step in preventing infection. However, this is typically done just before connecting the secondary line, not as the first step.
Choice C rationale:
Checking the IV site for signs of infiltration is indeed the first step. It’s important to ensure that the IV catheter is still properly placed in the vein and that there are no signs of infection or infiltration, which could cause complications.
Choice D rationale:
Connecting the tubing of the medication bag to the primary tubing is done after cleaning the port and before hanging the bag. It’s not the first step.
