Read the following clinical scenario to answer the questions that follow. This case will evolve throughout the chapter.

Guadalupe Himenez is a 32-year-old female client who presents to the oncology clinic for her first visit after recently being diagnosed with breast cancer. She initially saw her gynecologist after detecting a lump in her left breast. Her provider ordered a mammogram and biopsy, which determined the mass was malignant, and a surgeon performed a lumpectomy to remove it. The surgeon has referred her to the oncologist to start chemotherapy. Prior to this, she has been in good health without any chronic medical conditions.

Case Study 8.3.3 §8.3 source ↗

Read the following clinical scenario to answer the questions that follow. This case study is a follow-up to Case Study Part A.

Guadalupe Himenez has returned to the clinic for her first day of chemotherapy. Her treatment course will involve a combination of agents. Today she is receiving her first dose of paclitaxel (Taxol).

Prior to administering the Taxol, the nurse gives Guadalupe several medications including hydrocortisone and diphenhydramine. The client questions what these medications are for. What is the best response by the nurse?
  1. a.
    “To help stimulate your white blood count.”
  2. b.
    “To decrease the risk you will develop a hypersensitivity reaction to the Taxol.”
  3. c.
    “To decrease the risk of respiratory problems developing.”
  4. d.
    “To enhance the effectiveness of the medication.”

Answer

B. “To decrease the risk you will develop a hypersensitivity reaction to the Taxol.”
Taxol and other taxenes are likely to cause hypersensitivity reactions in clients receiving them. Premedicating the client with certain medications such as steroids, diphenhydramine, and histamine blockers will decrease the risk of these reactions.

Case Study 8.3.4 §8.3 source ↗

Read the following clinical scenario to answer the questions that follow. This case study is a follow-up to Case Study Part A.

Guadalupe Himenez has returned to the clinic for her first day of chemotherapy. Her treatment course will involve a combination of agents. Today she is receiving her first dose of paclitaxel (Taxol).
