NS325: Nutrition Through the Life Cycle
Unit 8 Older Adult Case Study
[Instructor Name]
[Date]
The woman, her history, measurements and medicines are composite; the protein position paper, acid suppression study, warfarin interaction review and B12 reference intake cited are real.
Presentation
E.K. is 83 and lives by herself in a walk-up apartment, one floor above the street, in Anderson, Indiana. Her husband died two years ago. She worked as a school cook for thirty years and still enjoys cooking, but now cooks only on Sundays. Her daughter drove her to a senior center health fair, where a nursing student weighed her and suggested a nutrition visit.
Measured values: weight 57.2 kg, against 61.3 kg recorded at her physician's office five months earlier, a loss of 4.1 kg or 6.7 percent. Height 160 cm, body mass index 22.3. A one-day recall showed about 1,150 kcal and 38 g of protein: tea and toast at breakfast, canned soup and crackers at lunch, and a small portion of Sunday's casserole in the evening.
Medicines: omeprazole, 20 mg each morning, taken for reflux since six years ago, and warfarin for atrial fibrillation, with her international normalized ratio checked monthly. She also takes a daily multivitamin "when I remember."
Assessment by Domain
Appetite and eating. Her lower denture rubs a sore spot on her gum, so she steers clear of meat, raw vegetables and other foods that take hard chewing. Food "tastes like nothing," which she attributes to age. She eats alone and says cooking for one feels pointless. The stairs make shopping a weekly trip with her daughter.
Nutrient adequacy. Her protein intake of 38 g is about 0.66 g per kilogram, below the adult RDA of 0.8 g/kg and well below the 1.0 to 1.2 g/kg suggested for healthy older adults by the PROT-AGE group (Bauer et al., 2013). Her energy intake does not cover her needs, as her weight loss confirms. Her diet is low in vitamin B12 sources apart from a little milk in her tea.
Medicines. Long-term acid suppression is associated with vitamin B12 deficiency: in a large health system study, people who had received two or more years' supply of a proton pump inhibitor had higher odds of a new B12 deficiency diagnosis (Lam et al., 2013). Warfarin's effect depends partly on vitamin K intake, and sudden changes in leafy green vegetables or vitamin K supplements can move the INR (Holbrook et al., 2005).
Where the Domains Meet
The case's problems feed one another.
1. Chewing narrows the diet. The sore denture pushes her toward soft, low-protein foods such as toast, soup and crackers, which lowers protein and B12 intake at the same time.
2. Acid suppression lowers what she absorbs. Stomach acid helps free vitamin B12 from the proteins in food. Six years of omeprazole may reduce how much B12 she can absorb from the small amounts of meat and dairy she still eats. Older adults already absorb food-bound B12 less well, which is why the reference intakes advise those over 50 to get most of their B12 from fortified foods or supplements (Institute of Medicine, 1998).
3. Erratic eating unsettles warfarin. Her prescriber set her warfarin dose against her diet at the time. If she now eats greens on Sundays only, or begins eating many more vegetables after advice to "eat better," her INR could swing. Consistency of vitamin K intake matters more than the amount.
4. Taste and loneliness lower intake further. Flat taste and eating alone both reduce the pleasure that drives eating, so the meals she does eat are small.
Each problem on its own looks minor, a sore gum, an old prescription, a lonely kitchen, but together they push her toward soft, low-protein food that she absorbs poorly and eats too little of, which is why she has lost nearly 7 percent of her weight in five months.
Function, Access and Daily Routine
Her day shapes her intake as much as her teeth do. She rises at 7:00, makes tea and toast, and spends the morning with the television and a crossword. Lunch is whatever can be heated in one pot. She climbs the stairs once a day to collect the mail and stops halfway to rest. Her daughter visits on Sundays, and that is the day she cooks a casserole, eating from it until Wednesday and then returning to soup.
Shopping is the bottleneck. Because she shops once a week with her daughter, fresh foods that spoil quickly, such as fish, soft fruit and fresh meat, rarely make it into the cart, and canned and dried foods fill the gaps. She lives on a pension and Social Security and says money is "tight but fine," though she buys store-brand soup by the case because it is cheap. A home-delivered meal program, or a grocery delivery service her daughter could order online, would change what is in the kitchen without adding trips on the stairs.
Monitoring
Progress would be judged by four measures over the next three months: monthly weight on the same scale, a repeat recall after any meal service begins, her INR results from the anticoagulation clinic, and the result of any B12 test her physician orders. A further loss of more than 2 kg, or any INR outside her target range, would prompt an earlier review.
Priorities
1. Protein and energy. A 6.7 percent loss in five months is significant. Soft protein foods that suit her teeth, such as eggs, yogurt, cottage cheese, beans, flaked fish and ground meat in sauces, can raise intake without chewing.
2. Vitamin B12 status. Her physician should be asked to consider checking B12, given her age, diet and long-term omeprazole.
3. Warfarin consistency. Any change in her diet, particularly in leafy greens, should be steady and shared with the clinic that manages her INR.
4. The denture. A dental visit to adjust the denture would remove the first link in the chain.
Referrals
1. Dentist, for denture adjustment.
2. Her physician, about B12 testing and whether long-term omeprazole is still needed, a decision that rests with the prescriber.
3. Anticoagulation clinic, informed of any planned diet change.
4. Registered dietitian, for an individualized plan.
5. Senior center congregate meals or home-delivered meals, to address eating alone and the stairs.
What the Case Does Not Settle
One recall cannot show her usual intake. Her flat taste may have causes beyond age, including medicines or zinc status, which a clinician would consider. Her weight five months ago came from a different scale. The case identifies priorities and the professionals who should address them; it does not make medical decisions.

The Purdue Global NS325 Unit 8 instructions
The Unit 8 case study asks students to assess an older adult across several domains and set priorities. Prompts usually provide history, measurements, diet and medicines. Present the facts first, including weight change as a percentage. Assess appetite, nutrient adequacy and medicines as separate domains. Then show how the domains interact. Compare protein intake with both the RDA and recommendations for older adults. Describe drug-nutrient interactions with sources, but leave dose and medicine changes to prescribers. Set priorities and name who should act on each. Include monitoring. Six pages is typical. Describe her daily routine and how she gets food, since access shapes intake. Keep the language plain enough that the client's family could follow it.
How this NS325 Unit 8 example is built
The case opens with her history, measurements, recall and medicines. Assessment covers appetite and eating, nutrient adequacy and medicines in turn. A section on interactions lists four links: chewing narrows the diet, acid suppression lowers B12 absorption, erratic eating unsettles warfarin and loneliness lowers intake. The highlighted sentence explains her weight loss as the sum of these. A section on daily routine and shopping shows how stairs and weekly trips shape her kitchen. Monitoring sets four measures. Four priorities and five referrals follow, and the closing section is honest about what one recall and one visit cannot show. Every interaction is cited to a study or review.
Where the points sit in the NS325 Unit 8 rubric
Older adult cases are usually graded on thorough assessment, accurate interactions, sound priorities and appropriate referrals. Points go to calculating weight loss correctly and stating its time frame. Explaining how problems feed one another earns more than listing them. Citing drug-nutrient interactions accurately shows care. Comparing protein with older-adult recommendations shows current knowledge. Referrals should match each problem. Organization and citations are also assessed. Cases that recommend changing medicines usually lose credit for scope. Including social factors such as eating alone is often credited. Linking each priority to a named professional shows an understanding of the care team. Setting monitoring measures with time frames is a sign of a complete plan.
Common NS325 Unit 8 mistakes, and how to avoid them
Older adult cases often list problems without showing how they connect. Another weakness is using the adult protein RDA without mentioning higher recommendations for older adults. Some cases advise stopping or changing a medicine, which belongs to the prescriber. Warfarin advice often tells clients to avoid greens rather than keep intake steady. Social and practical factors are skipped. Weight loss is reported without a percentage or time frame. Referrals are generic. If you have the case facts but are unsure how to organize them, start by asking which problem makes the others worse. A writer can build the case study from that chain. Treating access, such as stairs and shopping, as part of nutrition often reveals the easiest fix.

NS325 Unit 8 questions, answered
Which screening tool should an older adult case use?
Whichever the prompt names; the Mini Nutritional Assessment Short Form is common in courses like this one because it was built for older adults and includes appetite, weight loss, mobility and neuropsychological items. A case that reports the tool's result should quote its score bands exactly and note that screening flags risk rather than diagnosing malnutrition.
Can the case recommend a supplement drink?
It can say that oral nutrition supplements exist and when they are typically considered, but choosing one for a described woman on warfarin, with her own intake and medications, is a decision for a registered dietitian in consultation with her prescriber. The stronger papers present food-based options first and flag the supplement question for the professional who can answer it.
How can the case discuss medications without clinical training?
By describing the known interaction, citing it to an Office of Dietary Supplements fact sheet or to the drug's labeling, and stopping there. Naming the interaction shows understanding; proposing a change to a dose or a schedule is practice outside a nutrition role, and rubrics in this course treat it as a boundary error rather than as initiative.

Does long-term omeprazole affect vitamin B12?
Long-term acid suppression is associated with vitamin B12 deficiency. A large study found higher odds of deficiency among people with two or more years' supply of a proton pump inhibitor.
