A nurse is collecting data from a client following the administration of a new medication. Which of the following findings should the nurse identify as a manifestation of an allergic reaction?
Jaundice
Urticaria
Bradycardia
Hypertension
The Correct Answer is B
A. Jaundice. Jaundice, or yellowing of the skin and eyes, is a sign of liver dysfunction and may indicate hepatotoxicity rather than an allergic reaction. Some medications can cause drug-induced liver injury (DILI), but jaundice is not a typical symptom of an immediate hypersensitivity reaction.
B. Urticaria. Urticaria (hives) is a classic allergic reaction that appears as raised, red, itchy welts on the skin. It occurs due to the release of histamine in response to an allergen, which increases capillary permeability and leads to swelling and itching. Urticaria may be accompanied by angioedema, respiratory distress, or anaphylaxis, requiring immediate intervention if severe.
C. Bradycardia. Bradycardia (slow heart rate) is not a typical manifestation of an allergic reaction. While anaphylaxis can cause hypotension and tachycardia due to systemic vasodilation, bradycardia is more commonly associated with beta-blockers, heart block, or vagal stimulation rather than an allergic response.
D. Hypertension. Allergic reactions, especially severe ones like anaphylaxis, typically cause vasodilation and hypotension, not hypertension. While stress or anxiety related to an allergic episode may lead to a temporary rise in blood pressure, persistent hypertension is not a direct sign of an allergic reaction.

Explanation
Calculate the total daily dose:
Total daily dose (mg) = Weight (kg) x Dosage (mg/kg/day)
=14.9 kg x 40 mg/kg/day
= 596 mg/day
Calculate the dose per administration (divided into two doses):
Dose per administration (mg) = Total daily dose (mg) / Number of doses
= 596 mg/day / 2 doses
= 298 mg/dose
Calculate the volume to administer per dose:
Volume (mL) = Desired dose (mg) / Available concentration (mg/mL)
Available concentration = 250 mg / 5 mL
= 50 mg/mL
Volume (mL) = 298 mg / 50 mg/mL
= 5.96 mL/dose
Round to the nearest whole number:
5.96 mL is 6 mL/dose
Correct Answer is A
Explanation
A. Hemoglobin levels. Epoetin alfa stimulates erythropoiesis (red blood cell production) in clients with chronic renal failure, where natural erythropoietin production is impaired. The therapeutic effect of epoetin alfa is measured by monitoring hemoglobin (Hgb) levels to ensure adequate response without exceeding safe limits. Target Hgb levels should not exceed 11 g/dL, as higher levels increase the risk of thromboembolic events and hypertension.
B. Iron levels. While iron is necessary for red blood cell production, epoetin alfa does not directly affect iron levels. However, iron supplementation may be required if iron deficiency is present, as inadequate iron stores can limit the effectiveness of epoetin alfa therapy.
C. Platelet count. Epoetin alfa primarily affects red blood cell production and has no direct effect on platelet levels. Although polycythemia (excess red blood cells) can increase the risk of clot formation, platelet count is not the primary indicator of epoetin alfa’s therapeutic effects.
D. White blood cell count. Epoetin alfa does not impact white blood cell (WBC) production. Leukocyte production is regulated by different growth factors, and WBC monitoring is more relevant for conditions such as infections, chemotherapy-induced neutropenia, or bone marrow disorders.
