Final answer:
For an older adult with constipation and a new PEG tube, a standard 1 kcal/mL formula likely containing viscous fibers is the best option to promote gastrointestinal health and regularity. The correct option is 2.
Step-by-step explanation:
For an older adult nursing home resident with a history of constipation who has a newly placed percutaneous endoscopic gastrostomy (PEG) tube, selecting the most appropriate fiber formula is essential for promoting gastrointestinal health and regularity. Viscous fibers, such as beta-glucan and psyllium, are beneficial as they thicken the fecal mass, making it easier to pass. Therefore, the best choice of formula for this individual would likely be a formula with a higher content of these types of fibers.
Out of the given options, a standard 1 kcal/mL formula is typically designed to be closer to regular food intake and might include more of these important fibers compared to specialized formulas, but the exact choice should also consider the patient's overall nutritional needs and tolerability. As an older adult nursing home resident with a history of constipation, it is important to choose a fiber formula that can help promote regularity and improve bowel movements.
The standard 1 kcal/mL formula contains a moderate amount of fiber and provides a balanced nutritional profile, making it suitable for most individuals. The concentrated 2 kcal/mL formula may not be the best choice as it is higher in calories and may not provide sufficient fiber. The high protein (1 kcal/mL) formula is designed to provide additional protein, but it may not have a significant impact on constipation. The elemental 1.5 kcal/mL formula is typically used for individuals with impaired digestion or absorption and may not be necessary in this context.
