Final answer:
Hot formula can cause significant injury to a patient by causing burns, which are harmful and can lead to serious complications, including fatal outcomes.
Step-by-step explanation:
True - Hot formula or substances can indeed injure a patient. Burns result when skin is exposed to intense heat and can cause significant damage, leading to dehydration, electrolyte imbalance, and even renal and circulatory failure, which can be fatal. It is therefore crucial to handle heated substances carefully to prevent injury. In clinical settings, safe temperature ranges must be observed to avoid harmful effects. A temperature increase of more than about 3°C in tissue can be dangerous, and assuming high levels of heat retention, such as 95%, is unrealistic and could result in excessively high final temperatures that are detrimental to patient health.
