It can be difficult to refuse a well meant gift from a grateful patient or family member. If you are a nurse or a midwife, the Nursing and Midwifery (NMC) Code section 21 states you should:
Uphold your position as a registered nurse or midwife. To achieve this, you must....refuse all but the most trivial gifts, favours or hospitality as accepting them could be interpreted as an attempt to gain preferential treatment.
You can seek support from your manager who, in line with local policy, may be able to help you politely decline the gift.
