A nurse is collecting data from a client who has a new prescription for amoxicillin.
Which of the following findings indicates that the client is having an allergic reaction to the medication?

Choice A rationale:

Levalbuterol is a bronchodilator that relaxes muscles in the airways and increases air flow to the lungs. Therefore, a decrease in wheezing is a therapeutic effect of the medication, making this the correct choice.

Choice B rationale:

While levalbuterol can cause an increase in respiratory rate as a side effect, it is not considered a therapeutic effect of the medication. The primary goal of levalbuterol is to improve breathing by relaxing the muscles of the airways, not to increase respiratory rate.

Choice C rationale:

Levalbuterol does not directly affect nausea. It is primarily used to treat conditions related to breathing such as asthma and chronic obstructive pulmonary disease.

Choice D rationale:

An increased heart rate is a potential side effect of levalbuterol, not a therapeutic effect.

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.
