Introduction

Mrs. K’s case exemplifies the complex nutritional and health challenges faced by elderly individuals following a fall and fracture, compounded by depression, weight loss, and comorbidities such as hypertension and hyperlipidemia. Her nutritional assessment, requirement calculations, and risk factors provide insight into addressing her immediate health needs and guiding future interventions. This paper discusses her energy and protein requirements, evaluates her weight status, identifies nutritional risks, considers her vitamin B12 deficiency risk, recommends strategies to alleviate constipation, analyzes the implications of her medication, and suggests suitable assistance programs. Additionally, two questions related to adolescent anorexia nervosa and elderly health concerns are addressed with scientific references.

Energy and Protein Requirements

Mrs. K’s energy requirements are calculated using the Mifflin-St Jeor equation, which is recognized for its accuracy in estimating basal metabolic rate (BMR) in elderly individuals:

  • BMR for women = (10 × weight in kg) + (6.25 × height in cm) – (5 × age) – 161

Her weight: 170 lbs = 77.27 kg; height: 5 ft 3 in = 160 cm; age: 77 years.

Calculating BMR: (10 × 77.27) + (6.25 × 160) – (5 × 77) – 161 = 772.7 + 1000 – 385 – 161 = 1226.7 kcal/day.

Considering her decreased activity level and health status, an activity factor of 1.2 is appropriate:

Energy requirement = 1227 kcal × 1.2 ≈ 1472 kcal/day.

For protein needs, the general recommendation for elderly individuals is 1.0–1.2 g protein per kg body weight to prevent muscle loss:

Protein requirement = 1.2 g × 77.27 kg ≈ 92.7 g/day.

Assessment of Weight Loss and BMI

Her BMI is calculated as:

BMI = weight (kg) / height (m)^2 = 77.27 / (1.6)^2 = 77.27 / 2.56 ≈ 30.2 kg/m2.

This BMI indicates obesity; however, recent weight loss from 180 lbs to 170 lbs (~5.6%) over six months raises concern for unintentional weight loss, especially given her recent fall and decreased intake. The percentage weight loss exceeds the generally acceptable threshold of 5% over 6 months, raising clinical concern for malnutrition or underlying illness.

Appropriate Weight Goal

Given her BMI and health status, a weight stabilization or modest weight loss to reach a BMI of approximately 25–27 kg/m2 might be appropriate, focusing on improving nutrition and functional status rather than weight loss per se. The goal should consider her physical health, comorbidities, and personal preferences, with an emphasis on maintaining muscle mass and preventing further weight loss.

Nutritional Risk Factors

Three nutritional risk factors include:

  1. Reduced dietary intake: Her reported loss of taste, dental issues (poorly fitting dentures), and discomfort during eating lead to decreased food consumption, risking malnutrition.
  2. Physical health impairments: Her recent hip fracture limits mobility, reducing energy expenditure and appetite, further exacerbating nutritional deficits.
  3. Depression: She reports feelings of depression post-widowhood, which is associated with decreased appetite and dietary intake, compounding nutritional risk.

Vitamin B12 Deficiency and Food Sources

A deficiency in vitamin B12 can cause neurological symptoms, anemia, and cognitive decline. An important consequence is neurological impairment, which may be irreversible if untreated. Vegan or vegetarian diets can increase deficiency risk, but at her age, malabsorption is common.

A good dietary source of vitamin B12 is fortified foods or animal products such as lean beef, fish, eggs, and dairy. Specifically, shellfish (clams, oysters), liver, and fortified cereals are rich sources.

Strategies to Alleviate Constipation

  1. Increase fiber intake: Incorporate soluble and insoluble fiber-rich foods such as fruits, vegetables, whole grains, and legumes.
  2. Ensure adequate hydration: Encourage regular fluid intake, such as water or herbal teas, to soften stool and facilitate bowel movements.

Medication: Lasix (furosemide) and Nutrient Interactions

Lasix is a loop diuretic primarily used for managing edema and hypertension. It promotes diuresis, which can lead to electrolyte imbalances, notably potassium and magnesium depletion. Its use may also cause dehydration and impair renal function.

Nutrient interactions include increased excretion of potassium, leading to hypokalemia, which can result in irregular heart rhythms and muscle weakness. Monitoring electrolytes and supplementing potassium may be necessary during therapy.

Food Assistance Program Recommendation

For Mrs. K, the Older Americans Act Nutrition Program (congregate meals or home-delivered meals) would be suitable. It offers nutritious meals tailored for seniors, addresses potential isolation, and provides nutritional support essential for her age and health status.

Addressing Short Essays

Question 1: Anorexia Nervosa in Adolescent Boys

Recent research indicates that anorexia nervosa (AN) among adolescent boys presents with distinct features compared to girls. First, body image concerns in boys often focus on muscularity and leanness rather than thinness, leading to a drive for muscularity, which differs from the traditionally thin ideal in females (Grilo & White, 2017). Second, hormonal differences, particularly lower levels of estrogen and higher levels of testosterone, influence the presentation and progression of AN, often resulting in less amenorrhea and different physical symptoms (Keel & Forney, 2015). Third, social expectations and stigma may influence boys’ willingness to seek help, with concerns about masculinity and stigma impeding diagnosis and treatment (Mitchison et al., 2017). Addressing these unique features is crucial for early detection and intervention in male adolescents.

Question 2: Nutrients and Prevention of Pressure Ulcers

Pressure ulcers, common in hospitalized elderly patients, may be mitigated through adequate nutrition. Protein plays a pivotal role; sufficient intake supports collagen synthesis, tissue repair, and immune function. An increase in dietary protein from sources like lean meats, dairy, and legumes aids in wound healing (Baumgartner et al., 2019). Vitamin C is essential for collagen formation, and deficiency impairs wound healing—adequate intake through fruits and vegetables enhances tissue regeneration (Jull et al., 2018). Zinc is another critical mineral involved in cell proliferation and immune response; supplementation or diet rich in nuts, shellfish, and seeds can support healing (Lindsey et al., 2020).

Question 3: Counteracting Sarcopenic Obesity

Sarcopenic obesity, characterized by excess adiposity combined with loss of muscle mass, increases risk for frailty, falls, and metabolic disease. Strategies to counteract it include:

  1. Resistance training: Engaging in strength exercises stimulates muscle hypertrophy, improves functional capacity, and assists in fat loss (Peterson et al., 2018).
  2. Optimization of nutritional intake: Adequate protein consumption (1.2–1.5 g/kg/day) supports muscle synthesis; addition of omega-3 fatty acids can reduce inflammation and improve muscle function (Smith et al., 2019).
  3. Weight management through dietary modifications: A balanced diet emphasizing nutrient-dense foods, high-quality proteins, and controlled caloric intake supports fat loss while preserving muscle mass (Landi et al., 2020).

Conclusion

Mrs. K’s case underscores the importance of a comprehensive nutrition assessment and tailored interventions for elderly patients recovering from injury. Calculating caloric and protein needs provides benchmarks for diet planning. Recognizing her weight loss, nutritional risks, and medication interactions allows for targeted strategies to improve her health outcomes. Additionally, addressing specific concerns such as vitamin B12 deficiency, constipation, and medication effects ensures a holistic approach. The recommended assistance programs and evidence-based short-answer responses further support her nutritional and recovery goals, illustrating the complexity and importance of personalized care in aging populations.
