A nurse is caring for a client who has lung cancer and is receiving combination chemotherapy with cisplatin and etoposide. Which of the following interventions should the nurse implement to prevent nephrotoxicity from cisplatin?
Administer mannitol as prescribed before cisplatin infusion.
Monitor serum creatinine and blood urea nitrogen levels daily.
Encourage fluid intake of at least 3 L per day during treatment.
All of the above.
The Correct Answer is D
Choice D reason:
These are all interventions that can prevent nephrotoxicity from cisplatin, which is a potent and valuable chemotherapy drug that can cause kidney damage or failure. Nephrotoxicity is one of the most serious and doselimiting adverse effects of cisplatin, which can affect up to 30% of patients. Nephrotoxicity is caused by the accumulation of cisplatin in the renal tubular cells, leading to cell injury, inflammation, and ischemia³.
Choice A reason:
Administering mannitol as prescribed before cisplatin infusion can prevent nephrotoxicity by increasing urine output and reducing the concentration of cisplatin in the kidney. Mannitol is an osmotic diuretic that draws water from the extracellular space into the tubular lumen, thereby increasing urine volume and flow rate. Mannitol can also scavenge free radicals and reduce oxidative stress induced by cisplatin⁴.
Choice B reason:
Monitoring serum creatinine and blood urea nitrogen levels daily can prevent nephrotoxicity by detecting early signs of renal impairment and adjusting the dose of cisplatin accordingly. Serum creatinine and blood urea nitrogen are markers of kidney function that reflect the glomerular filtration rate (GFR). An increase in these levels indicates a decrease in GFR and a loss of kidney function. The dose of cisplatin should be reduced or withheld if serum creatinine or blood urea nitrogen levels rise above a certain threshold⁴.
Choice C reason:
Encouraging fluid intake of at least 3 L per day during treatment can prevent nephrotoxicity by maintaining adequate hydration and preventing dehydration. Hydration is essential for preventing cisplatininduced renal toxicity, as it dilutes the concentration of cisplatin in the kidney and enhances its elimination. Dehydration can increase the risk of nephrotoxicity by reducing renal blood flow and causing tubular obstruction by uric acid crystals. Fluid intake can be oral or intravenous, depending on the patient's condition⁴.

Correct Answer is D
Explanation
Choice A reason:
Blood pressure and pulse should be monitored before and during the infusion of trastuzumab, as this drug can cause cardiomyopathy and heart failure in some patients. These are serious side effects that can affect the heart's ability to pump blood effectively.
Choice B reason:
Respiratory rate and oxygen saturation should be monitored before and during the infusion of trastuzumab, as this drug can cause infusion reactions and pulmonary toxicity in some patients³. These are serious side effects that can affect the lungs' ability to exchange oxygen and carbon dioxide.
Choice C reason:
Temperature and skin condition should be monitored before and during the infusion of trastuzumab, as this drug can cause fever, chills, rash, and infection in some patients. These are common side effects that can indicate an allergic reaction or an infection.
Choice D reason:
All of the above assessments should be performed before and during the infusion of trastuzumab, as this drug can cause various side effects that can affect the heart, lungs, skin, and immune system of the patient. The nurse should also monitor for other signs and symptoms such as nausea, vomiting, diarrhea, headache, cough, sore throat, etc. The nurse should report any abnormal findings to the doctor and intervene as needed.
Correct Answer is ["A","B","C"]
Explanation
Choice A reason:
Pallor and weakness are signs of anemia, as they indicate a low level of hemoglobin or red blood cells that carry oxygen to the tissues. Pallor is the loss of color in the skin, especially in the face, nails, and inside of the eyelids. Weakness is the feeling of having less energy or strength than usual.
Choice B reason:
Dizziness and headache are signs of anemia, as they indicate a low level of oxygen in the brain. Dizziness is the feeling of being lightheaded or unsteady. Headache is the pain or discomfort in the head, scalp, or neck.
Choice C reason:
Shortness of breath and tachycardia are signs of anemia, as they indicate a low level of oxygen in the lungs and heart. Shortness of breath is the feeling of not being able to breathe enough or catch your breath. Tachycardia is the abnormally fast or irregular heartbeat.
Choice D reason:
Constipation and abdominal pain are not directly related to anemia or fatigue, but may indicate other conditions such as dehydration, bowel obstruction, or infection. Constipation is the difficulty or infrequency in passing stools. Abdominal pain is the pain or discomfort in the stomach or belly area.
Choice E reason:
Difficulty sleeping and concentrating are not directly related to anemia or fatigue, but may indicate other conditions such as stress, depression, or anxiety. Difficulty sleeping is the trouble falling asleep or staying asleep. Difficulty concentrating is the trouble focusing on tasks or remembering things.
