State three appropriate nutrition diagnoses for Señora Mendez. For each one, describe: * one potential nutrition intervention, and * a nutrition-related indicator that could be used to monitor and evaluate Señora Mendez Please separate your answers with numbers.
1. She can be diagnosed with low vitamin D levels. A possible nutrition intervention could be adding a vitamin D supplement into her daily life. A recommended vitamin D supplement would have roughly 2000 IU per day. This can be tracked simply by a dietitian or clinician asking her if she is taking her supplement. A more specific approach would be taking blood samples and determining the plasma levels of 25-hydroxyvitamin D (ensuring that they are no longer low and that the supplement has been helpful). 2. She can also be diagnosed with low intake of DHA/EPA (omega 3). This was known via her food diary which largely excluded foods sources containing DHA/EPA. One possible nutrition intervention would be a higher calorie diet, consisting of some fish that is high in omega 3 (yet is low in mercury, such as salmon). A way to monitor this would be to ask her to keep a food diary, and ensuring that there are foods high in DHA/EPA in her diet throughout the rest of her pregnancy. 3. Lastly, a third nutrition diagnosis for Señora Mendez would be low caloric intake. This is related to her nausea, and is evidenced by low weight gain and seen by her dietary history. A nutrition intervention would simply be getting her to eat more, specifically foods that do not make her nauseous (carb-rich). A nutrition indicator would be weight gain and tracking of her nutrition. Dehydration signs are important to look out for too. All three of those are possible nutrition-related indicators that could be used to monitor her weight gain and increase her caloric intake.

At 37 years of age, Senora Mendez was in her 23rd week of pregnancy and expecting her second child. Or so she thought, until an ultrasound detected twins. Her pre-pregnancy weight was 142 pounds and her BMI was 23. Senora Mendez's weight-gain progress has been poor due to nausea and vomiting experienced in the first half of pregnancy. Otherwise, she was experiencing a normal pregnancy for women expecting twins. Concerns about her weight-gain progress and the nutritional needs of women with twin gestation prompted her certified-nurse midwife to prescribe a prenatal vitamin and mineral supplement and to refer her to a registered dietitian/certified diabetes educator. A nutritional assessment completed during week 25 of pregnancy identified that she wad gained 14 pounds since conception, and that her typical dietary intake excluded food sources of EPA and DHA. Her plasma 25-hydroxyvitamin D level was below 24 nmol/L, indicating low vitamin D status. No other nutrition-related problems were identified.

List 4 factors that may put a nursing mother at nutritional risk.
First, a mother who does not have a high level of food security may be at risk. Because of her lack of access to healthy, abundant, quality food, she may not be getting the nutrients (and energy) that she and her baby need. Second, another risk factor putting a nursing mother at nutritional risk would be an eating disorder. Although most eating disorder sufferers are okay during pregnancy, many return to their dieting and other rituals post partum. If the mother is engaging in extreme dieting and weight loss during the nursing period, she is likely not getting enough calories to support her and her baby (via breastfeeding). Third, post partum depression is another risk factor for putting nursing mothers at risk. If the mother is struggling to get out of bed or leave the house, she may be less inclined to prepare healthy meals for herself or even to take care of herself as a whole. Lastly, a fourth risk factor that puts nursing mothers at risk is drugs, alcohol, and tobacco abuse. Not only is this extremely harmful behavior for anyone, but it is especially harmful for the nursing mom.
Describe two situations where breastfeeding beyond 1 year can have a significant impact on the child's health.
First, infants at risk for malnutrition, such as those at risk for developing kwashiorkor, can be greatly impacted by breastfeeding beyond one year. By continued breastfeeding, the baby gets continued sources of protein, which prevents protein malnutrition. Protein is stable through the second year. Second, babies who are picky eaters may not be getting optimal nutrition if not breastfed. If they are breastfed, the breastmilk is providing additional calories, macronutrients, and all sorts of protective elements that the baby needs.
Summarize the 12 steps in preparing a bottle of formula for a baby.
First, one must have a clean surface area on which to prepare the bottle. This prevents possible contamination or germs getting into the formula bottle and thus ingested by the infant. Second, the person who is preparing the bottle should wash their hands. Next, the water ought to be boiled. Fourth, the amount of formula to water should be understood (via the packaging). Fifth, the water should be poured into the bottle preventing scalding. Next, formula should be added. After the formula and water are in the bottle, shake it to mix. Eighth, run the bottle under cool water to cool the bottle down. Next, one must dry the outside of the bottle. Then, one should check the temperature of the formula by squirting a little on one's arm. Once the temperature has appropriately cooled down, the infant should be fed (ideally via paced bottle feeding method). Lastly, any formula not eaten within two hours should be thrown away.
Name at least three physiological mechanisms that contribute to nutritional challenges in preterm infants.
First, preterm infants often get tired during feedings when compared to term infant feeding. They have to expend much more energy during feedings than term infants, and so they are more tired. This can lead to difficulty getting them to eat enough and ultimately them getting enough nutrients. Second, they cannot tolerate a lot of volume in feedings. This makes it difficult to feed them an adequate amount so they are getting enough nutrition (hence, why fortification is often necessary). Third, the CNS (central nervous system) does not signal hunger like it does in term infants. Because the baby cannot regulate it's own hunger, a schedule has to be put in place to ensure that its nutritional needs are being met. Fourth, they have unstable feeding positions (such as their heads being too forward), which can make feeding difficult.
List 3 ways to support Taylor's mother with breastfeeding.
First, setting Taylor's mother up with appointments/consultations with lactation consultants, nurses, and pediatricians who can help keep her on track or help her with any breastfeeding issues is one way she can be supported in her decision to breastfeed. Secondly, she should be able to keep the breast pump (ideally hospital grade) until the infant is term and then for another 4-8 weeks. Lastly, getting Taylor's mom involved in peer support groups for other women who are pregnant/nursing is important. For example, this involvement can be done at WIC clinics. Lastly, giving Taylor's mom the proper evidence-based information about breastfeeding is important. For example, showing her data on how breastfeeding promotes optimal growth and development of of her infant is key.

Is Taylor able to consume > 180 ml/kg/day? How do you know?
For Taylor's weight of 2.1 kg, he would need to consume 378 mL/day in order to consume greater than 180 ml/kg/day (180 mL x 2.1 kg). Given his feedings of 2-3 ounces per feeding and feeding 4-5 times per day (and that one ounce is roughly 30 mL), this gives a range of 240 mL-450 mL per day. Assuming Taylor is usually feeding on the upper range of this spectrum, he is likely able to consume > 180 ml/kg/day.
Create a meal plan for one day that would be considered a healthy diet for a nursing mother. Begin your answer by including the approximate amount of calories she needs to consume EXTRA per day because she is nursing. Note: you do not need to do any kind of nutritional analysis for this question. And please break up your answer by: breakfast, lunch, dinner, and snacks.
For a nursing mother, she needs approximately 2700 calories per day (a range of 1800 to 2700). This is because nursing (milk production) requires an extra 670 calories per day (500 calories per day from intake and 170 calories from fat stores). In general, her nutritional demands (in addition to excess calories) are increased protein and carbohydrate demands, as well as increase demands for some minerals. First, I would suggest she take a multivitamin. For breakfast, I would suggest a bowl of oatmeal (made with milk), topped with banana and peanut butter. To drink, I would suggest a glass of OJ. This would provide roughly 500 calories. Perhaps for a mid morning snack she could reach for a greek yogurt or a cheese stick and a piece of fruit (120-150 calories). For lunch, a big salad topped with chicken, avocado, black beans, corn, greek yogurt dressing, and lots of veggies could allot her another 500 calories. As an afternoon snack, a piece of whole wheat bread with peanut butter, and a glass of milk may tide her over until dinner (300 calories). For dinner, a bowl of whole wheat pasta, meatballs, spaghetti sauce, and a side salad would provide her with fiber, carbohydrates, protein, and some fat from an oil-based Italian dressing. Dinner would be roughly 600-700 calories. Post dinner, her calorie intake is at 2100-2200. Ideally, one would want this nursing mother to meet the 2700 calorie mark. Thus, an evening snack high in mono or polyunsatured fats, which are calorie dense, would be a great way to help her meet her needs. A couple handfuls of walnuts, a piece of fruit, and a glass of milk (or another fruit choice) could add another 500 calories, brining her total to roughly 2600-2700 calories. This meal plan accounts for the increased energy expenditure required by nursing (an extra 670 calories per day), and it includes all of the macronutrients a woman needs (higher carbohydrate intake, more protein, and healthy fats). It is includes vitamins and minerals from whole wheat breads, fruits and vegetables, and a multivitamin. Ideally, carbohydrates would be 45-65%, protein 10-35%, and fat 20-35%. By providing a diet rich in macronutrients and micronutrients, as well as energy, this daily meal plan should be sufficient to meet the demands placed upon a nursing mother.
How does human milk serve as a mechanism to involve Taylor's mother in NICU care?
For mothers in the NICU, it is very difficult to watch their baby be taken care of by doctors, nurses, and other healthcare professionals around the clock. It is easy for mothers to become detached or feel helpless. Human milk serves as a mechanism to involve Taylor's mother in his care by allowing his mother to feel like she is doing her part, helping her to feel less "helpless." More so, it involves her in his care, showing her that she is a major reason why he would be improving (her feeling like "I did that! I am helping him grow!"). More so, the skin to skin contact that human feeding allows can help with development. Overall, involving Taylor's mom in his care via human milk allows her to feel included in his care and treatment, to feel less helpless, and to provide a means to foster his growth and development.

Malnutrition is a multifactorial problem with numerous causes. Please describe 2 causes other than "lack of access to food," using the UNICEF Framework of Under Nutrition.
Other than "lack of access to food," malnutrition can be caused by lack of access to healthcare and a lack of knowledge or ability of a caregiver to provide proper care. Lack of healthcare can be a lack of access to a facility or clinic, lack of immunizations, or lack of regular checkups, to name a few. This lack of healthcare can have devastating affects upon a child's health. More so, lack of care can mean that the caregiver is absent or simply doesn't possess the knowledge or skills needed or required to care for the child adequately. An example of this would be lack of knowledge about the importance of breastfeeding, about ensuring a clean water supply in preparing formula, or about proper cleansing and hygiene techniques.

Assume she will deliver toward the end of week 37 and is now in the beginning of week 25. How many pounds should be set as a goal for weekly weight gain if a total pregnancy gain at the midpoint of the provisionally recommended range for weight gain in twin pregnancy is to be achieved? Justify your answer.
The midpoint for her weight gain goals would be 45.5 pounds (as that is the midpoint of 37 to 54 pounds, her recommended weight gain range). Currently, she has gained 14 pounds. 45.5 subtracted by 14 is 31.5. Since she has twelve more weeks to go (25 to 37 weeks), she should gain roughly 2.6 pounds per week in order to hit the midpoint of her weight gain range by the time she delivers.

List and describe: 1) Three causes of undernutrition 2) Three results of undernutrition 3) Three interventions that may be successful in preventing undernutrition
There are many causes of undernutrition. First, there are basic causes of undernutrition. This can be divided into social (is there war going on that would stop the food supply?), economic (is employment down?), and political (is there corruption that would prohibit supplements getting to the people?). Second, there are underlying causes of under nutrition. These are lack of access to food, lack of access to healthcare, and lack of access to adequate care. Lastly, undernutrition can be caused by immediate causes, whether that be inadequate dietary intake or disease. There are many results of undernutrition. First, undernutrition can result in mortality or morbidity, also known as sickness or even death. Second, undernutrition can result in long term effects upon adult health such as height, cognitive scores, and cardiovascular disease. Lastly, undernutrition can result in economic issues; if people are chronically undernourished, their capacity for working and stimulating the economy is diminished. Furthermore, there are several interventions that may be successful in preventing undernutrition. First, supplementing the food supply via fortification, RUTF, or lipid-based supplements is a possible way to prevent undernutrition. Specifically, for children who are quite underweight, RUTF offer a way for them to get the calories and vitamins they desperately need. Next, PATH, an intervention aimed at ensuring and starting donor milk banks helps ensure babies are given the proper nutrition at a young age. Lastly, an intervention called "Scaling up Nutrition" aims to utilize governments, civilians, the private sector, and other to instigate change that decreases malnutrition and gets "nutrition justice for all." This has a multifactorial approach and several nutrient interventions.
Explain why research shows that pregnant women should eat frequently. Discuss what could happen if she goes a long period of time without eating.
There are many reasons why research shows that pregnant women should eat frequently. First, eating regularly helps maintain the mother's metabolism. It prevents binging, and it also prevents drops in blood sugar. More so, not eating frequently increases the mother's levels of corticotropin-releasing hormone. Specifically, going more than thirteen hours without eating greatly increases CRH. Since there is an inverse relationship between serum CRH levels and gestational age at delivery, if a mother frequently goes long periods without eating (thereby increasing her CRH levels), she and her baby have a higher likelihood to experience a premature birth.

List and discuss three benefits of breastfeeding for the mother and three for the baby. Alternatively, you could also word your answers by listing the risks of not breastfeeding for the mother and baby. Please structure your essay like this:
Three benefits for breastfeeding for the mother are strong bonding with the infant, increased energy expenditure (faster return to pre-pregnancy weight), and decreased postpartum bleeding. First, the release of oxytocin while breastfeeding creates a strong bond between mother and baby. Second, the energy (calories) expended via breastfeeding allows the mom the ability to return to her pre-pregnancy weight faster than had she formula fed. Her body is using energy making the breastmilk (Especially during the second year, where the fat source is being made in the mammary glands versus fat storage from pregnancy)! Third, the decreased postpartum bleeding is due to the fact that oxytocin decreases uterine contractions. Three benefits for the baby are optimal nutrition, enhanced immune system, and strong bonding. The benefit of optimal nutrition is due to the fact that the breastmilk is perfectly attuned to the needs of the baby. It has adequate macronutrients and other elements that help the baby's growth and development. The enhanced immune system is due to the mother passing along her antibodies and protective elements to the baby. Also, breastmilk contains lysozyme and sIgA, both of which hinder the baby's less developed immune system from pathogens (lysozyme harms gram positive and some gram negative cell walls and sIgA binds to the microorganisms). Lastly, the baby benefits by a strong bond between mother and baby. The skin to skin contact that breastfeeding supplies allows the baby warmth and fosters a protective, nurturing bond.
