A nurse is caring for a client who has Graves' disease and is to start therapy with propylthiouracil. The nurse should expect which of the following outcomes?
Increased Hct
Decreased WBC count
Decreased heart rate
Increased blood pressure
The Correct Answer is C
A. Increased Hct. Propylthiouracil (PTU) is an antithyroid medication that reduces excessive thyroid hormone production in Graves' disease. It does not directly affect hematocrit (Hct) levels. While anemia can occur in some clients with untreated hyperthyroidism, PTU itself is not expected to raise Hct.
B. Decreased WBC count. A serious adverse effect of PTU is agranulocytosis, which results in a dangerously low white blood cell (WBC) count, increasing the risk of infection. However, this is a potential complication rather than an expected therapeutic outcome. Clients on PTU require regular monitoring of WBC levels to detect early signs of agranulocytosis.
C. Decreased heart rate. Graves’ disease causes hyperthyroidism, which increases metabolism and leads to symptoms such as tachycardia. PTU works by inhibiting thyroid hormone synthesis, leading to a gradual reduction in heart rate as thyroid function normalizes. This is a desired outcome of treatment, helping to reduce cardiovascular strain associated with hyperthyroidism.
D. Increased blood pressure. Hyperthyroidism can cause elevated blood pressure due to increased cardiac output. As PTU lowers thyroid hormone levels, blood pressure is expected to decrease or stabilize rather than increase. An increase in blood pressure would be unexpected and may indicate another underlying issue requiring evaluation.

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.
Correct Answer is C
Explanation
A. Hypertension. Filgrastim, a granulocyte colony-stimulating factor (G-CSF), primarily stimulates white blood cell production. While minor blood pressure fluctuations can occur, hypertension is not a common or significant adverse effect. Monitoring blood pressure is important, but sustained hypertension is not expected.
B. Fluid retention. Filgrastim does not typically cause significant fluid retention. Medications such as corticosteroids or certain chemotherapeutic agents are more likely to lead to fluid overload. While rare cases of capillary leak syndrome have been reported, general fluid retention is not a primary concern.
C. Bone pain. Bone pain is the most common adverse effect of filgrastim. The medication stimulates bone marrow activity, leading to increased production of neutrophils, which can cause discomfort in bones, particularly in long bones such as the femur and sternum. Pain is usually mild to moderate and can be managed with acetaminophen or NSAIDs if appropriate.
D. Hypokalemia. Filgrastim does not have a direct effect on potassium levels. Electrolyte imbalances are more commonly associated with diuretics, corticosteroids, or chemotherapy. Clients on filgrastim typically do not require routine potassium monitoring unless other risk factors are present.
