Final answer:
To calculate Emily's parenteral nutrition needs, a personalized assessment is carried out considering her weight, age, sex, and activity level. For dehydration, IV fluids like normal saline or lactated Ringer's solution are given to replenish water and electrolytes.
Step-by-step explanation:
For a patient like Emily who has recently had peripheral access placed for parenteral nutrition, calculation of her nutritional needs must be individualized and typically involves a multidisciplinary approach. This process would include an assessment of her current nutritional status, energy requirements, and fluid and electrolyte needs.
To calculate her nutritional needs, clinicians often use formulas that take into account factors like weight, age, sex, and level of activity. For fluid administration, a dehydrated human patient may be given intravenous (IV) fluids such as normal saline, lactated Ringer's solution, or a dextrose solution, depending on the underlying cause of dehydration and the patient's current electrolyte balance.
These IV fluids help to restore the proper balance of water and electrolytes in the body, ensuring hydration and aiding in the delivery of nutrients when oral intake is not possible or adequate.
