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 B
Explanation
Choice A rationale:
Asking the client to demonstrate dose delivery can be part of patient education and helps ensure that the client understands how to use the PCA device. This action does not require intervention.
Choice B rationale:
The nurse administering a PCA dose for the client requires intervention. PCA stands for “Patient-Controlled Analgesia,” meaning that only the patient should administer doses to themselves. This prevents overdosing and ensures that pain medication is administered according to the patient’s needs.
Choice C rationale:
Reassuring the client that the PCA device will not cause an overdose is appropriate because PCA devices are designed with safety measures to prevent overdosing.
Choice D rationale:
Monitoring for oversedation is an important part of care for a client using a PCA device. This action does not require intervention.
Correct Answer is C
Explanation
Choice Arationale:
The statement about taking the medication with food is incorrect. Nitroglycerin sublingual tablets should not be taken with food. They work much faster when absorbed through the lining of the mouth.
Choice B rationale:
The statement that the medication can slow the heart rate is incorrect. Nitroglycerin does not slow the heart rate. In fact, it can cause a reflex tachycardia, where the heart rate increases.
Choice C rationale:
The statement that the effects of the medication should be felt within 5 minutes is correct. This indicates an understanding of the instructions.
Choice Drationale:
Taking the medication every 10 minutes until the pain goes away is incorrect. Nitroglycerin sublingual tablets usually give relief in 1 to 5 minutes. However, if the pain is not relieved, a second tablet can be taken 5 minutes after the first tablet. If the pain continues for another 5 minutes, a third tablet may be used. Taking the medication every 10 minutes could lead to an overdose.
