A nurse is caring for a client who has prostate cancer and is receiving chemotherapy that causes anemia and neutropenia. The nurse should identify that which of the following drugs can be used to treat both conditions by stimulating the production of red blood cells and neutrophils in the bone marrow? (Select all that apply.)

Choice D reason:

These are manifestations of neurotoxicity from vincristine, which is a chemotherapy drug that belongs to the vinca alkaloids. Vinca alkaloids work by binding to tubulin and inhibiting the formation of microtubules, which are essential for cell division and function. Neurotoxicity is one of the most common and doselimiting adverse effects of vincristine, which can affect up to 80% of patients. Neurotoxicity can manifest as peripheral neuropathy, which is the damage to the nerves in the hands and feet, causing numbness, tingling, burning, or pain. The nurse should monitor the client for peripheral neuropathy and provide pain relief and supportive care as needed³.

Choice A reason:

These are not manifestations of neurotoxicity from vincristine, but rather of paralytic ileus from vincristine. Paralytic ileus is the loss of intestinal motility, causing constipation, urinary retention, and abdominal distension. Paralytic ileus is another common adverse effect of vincristine, which can affect up to 40% of patients. Paralytic ileus is caused by the inhibition of microtubules in the smooth muscle cells of the intestine and bladder, leading to reduced peristalsis and urine flow. The nurse should monitor the client for paralytic ileus and provide laxatives, catheterization, and fluids as ordered⁴.

Choice B reason:

These are not manifestations of neurotoxicity from vincristine, but rather of ototoxicity from cisplatin, which is another chemotherapy drug that is used in combination with vincristine and prednisone for lymphoma. Ototoxicity is the damage to the inner ear or hearing nerve, causing hearing loss, tinnitus, and vertigo. Ototoxicity is one of the most serious and doselimiting adverse effects of cisplatin, which can affect up to 50% of patients. Ototoxicity is caused by the accumulation of cisplatin in the cochlea and vestibular system, leading to oxidative stress and cell death. The nurse should monitor the client for ototoxicity and provide hearing tests and vestibular rehabilitation as needed .

Choice C reason:

These are not manifestations of neurotoxicity from vincristine, but rather of ocular toxicity from rituximab, which is another chemotherapy drug that is used in combination with vincristine and prednisone for lymphoma. Ocular toxicity is the damage to the eyes or vision, causing blurred vision, photophobia, and eye irritation. Ocular toxicity is a rare but serious adverse effect of rituximab, which can affect up to 1% of patients. Ocular toxicity is caused by the infusionrelated reactions or immunemediated reactions induced by rituximab, leading to inflammation and edema in the eyes. The nurse should monitor the client for ocular toxicity and provide eye drops and steroids as ordered .

Choice A reason:

Numbness, tingling, or pain in the extremities are signs of peripheral neuropathy, which is a common and serious side effect of thalidomide³. This condition can affect the nerves that control sensation and movement in the arms and legs, and can lead to permanent nerve damage if not treated.

Choice B reason:

Drowsiness, dizziness, or confusion are signs of central nervous system depression, which is a common and serious side effect of thalidomide³. This condition can affect the brain's ability to regulate alertness, cognition, and coordination, and can increase the risk of falls, accidents, and injuries.

Choice C reason:

Constipation, nausea, or vomiting are signs of gastrointestinal distress, which is a common and mild side effect of thalidomide. This condition can affect the digestive system's ability to process food and fluids, and can lead to dehydration, malnutrition, and electrolyte imbalance if not managed.

Choice D reason:

Swelling, redness, or warmth in the legs are not directly related to thalidomide use, but may indicate a deep vein thrombosis (DVT), which is a blood clot that forms in a vein deep in the body. Thalidomide can increase the risk of DVT by affecting the blood's ability to clot normally. A DVT can be lifethreatening if it breaks off and travels to the lungs, causing a pulmonary embolism.

Choice E reason:

Rash, itching, or hives are signs of allergic reaction, which is a rare but serious side effect of thalidomide³. This condition can affect the skin's immune response to the drug, and can lead to severe skin reactions such as StevensJohnson syndrome or toxic epidermal necrolysis if not treated.
