The nurse has an order to administer oprelvekin (Neumega) to a patient for the first time. Before administering the drug, what allergy would the nurse want to specifically question the patient about?

Correct Answer: B

Rationale: The correct answer is B: Escherichia coli-produced products. Oprelvekin is produced using genetically modified E. coli bacteria. The nurse should question the patient about any allergies to E. coli-produced products to prevent an allergic reaction. Choices A, C, and D are incorrect because oprelvekin is not derived from egg products, lactose, or penicillin.

Correct Answer: B

Rationale: The correct answer is B: Increasing fluids. In a patient with acute myelocytic leukemia receiving sargramostim, hydration is crucial to prevent dehydration and maintain renal function due to the potential for increased urine output. Adequate fluids help prevent complications such as renal impairment and electrolyte imbalances. Providing a quiet environment (A) can be beneficial but not the priority. Comfort measures for nausea (C) are important but do not address the immediate need for hydration. Encouraging appropriate dietary intake (D) is important but not as critical as ensuring adequate fluid intake in this scenario.

Correct Answer: A

Rationale: The correct answer is A: Blocking normal effects of the immune system. Immune suppressants are prescribed post-organ transplant to prevent rejection by inhibiting the immune system's response against the new organ. By blocking the immune system's normal function, these medications help maintain the transplanted organ's viability. Explanation for incorrect choices: B: Stimulating the immune system to fight off infection contradicts the purpose of immune suppressants, which aim to dampen the immune response. C: Working with corticosteroids to enhance healing is not the primary mechanism of action of immune suppressants. D: Working with corticosteroids to promote suppressor cells is not accurate as immune suppressants primarily target different pathways compared to corticosteroids.

Correct Answer: C

Rationale: The correct answer is C: Interferon alfa 2b. This is the appropriate drug for Kaposi's sarcoma treatment due to its antiviral and immunomodulatory properties. Interferon alfa 2b is commonly used in the treatment of this condition. Interferon beta1a (A) is used for multiple sclerosis, not Kaposi's sarcoma. Interferon gamma 1b (B) is mainly used for chronic granulomatous disease. Peginterferon alfa 2b (D) is used for hepatitis C treatment, not Kaposi's sarcoma. Therefore, the correct choice is Interferon alfa 2b for this patient.

Correct Answer: A

Rationale: The correct answer is A: Palivizumab. Palivizumab is specifically designed to prevent RSV in high-risk children by targeting the virus. Natalizumab is used for multiple sclerosis, Belimumab for lupus, and Eculizumab for paroxysmal nocturnal hemoglobinuria. These choices are incorrect as they do not target RSV.
