Final answer:
The correct answer is C, "I should keep my skin moisturized with dye-free lotion," as it indicates proper skin care while undergoing cetuximab treatment, which can cause skin reactions.
Step-by-step explanation:
When considering effective patient teaching for someone who is receiving cetuximab, it's important to focus on skin care as cetuximab can cause skin reactions. Among the provided statements, the one that demonstrates evidence of effective teaching is C. "I should keep my skin moisturized with dye-free lotion." This is because cetuximab can cause dryness and rash, and keeping the skin moisturized with a gentle, dye-free product can help manage these side effects.
Other care instructions that would support effective teaching include using alcohol-free products, avoiding irritating skin products such as harsh astringents or exfoliants, and rinsing with lukewarm water rather than very hot or cold water. This is to prevent further irritation or damage to the skin, which is especially sensitive during cancer treatments like chemotherapy.
Options A and B, involving bathing in extra hot water daily and rubbing vigorously with a towel, can further irritate the skin and should be avoided. Regarding option D, the use of over-the-counter acne creams is not recommended without professional advice, as these may not be suitable for the skin reactions caused by cetuximab and can potentially worsen the condition.
