Final answer:
A child with spina bifida should never have their temperature taken rectally due to the risk of infection. Alternate methods, such as using an oral or ear thermometer, should be used instead.
Step-by-step explanation:
A child with spina bifida should never have their temperature taken rectally. This is because individuals with spina bifida have a higher risk of developing infections, and taking their temperature rectally can increase this risk. It is important to use alternate methods for measuring the temperature in these cases, such as using an oral or ear thermometer.
