Malnutrition Flashcards
Three Forms of Protein-Energy Metabolism (PEM)
Marasmus
Kwashiorkor
Marasmic-Kwashiorkor
Malnutrition
Protein catabolism exceeds protein intake and synthesis, resulting in negative nitrogen balance, weight loss, decreased muscle mass, and weakness
Results from inadequate nutrient intake, increased nutrient losses, and increased nutrient requirements.
Common Complications of Severe Malnutrition
- Leanness and cachexia (muscle wasting with prolonged malnutrition)
- Decreased activity tolerance
- Lethargy
- Dry, flaking skin and various types of dermatitis
- Poor wound healing
- Infection, particularly sepsis
- Possible Death
- Brittle nails and hair
- Weakness
Marasmus
Calorie malnutrition in which body fat and protein are wasted
Kwashiorkor
Lack of protein quantity and quality in the presence of adequate calories
Marasmus-Kwashiorkor
Combined protein and energy malnutrition
GERD
Backflow of stomach acid into the esophageal area
Three Major Types of Medications for GERD and Peptic Ulcers
Antacids
Histamine blockers
Proton pump inhibitors
Is it better to take liquid or tablet form of antacids?
Liquid - it coats the esophagus
Three Common Names of HT Antagonists Medications?
Zantac
Pepcid
Axid
Histamine2 Receptor Antagonists
Reduce the secretion of acid
Antacids
Neutralize excess acid
Types of Antacids
Maalox
Mylanta
Gaviscon
Protein Pump Inhibitors
Reduce gastric acid secretion and can be given in a single daily dose
Common Names of PPIs
Omeprazole (Prilosec) Rabeprazole (AcipHex) Pantoprazole (Protonix) Esomeprazole (Nexium) Lansoprazole (Prevacid)
Stress Ulcers
Acute gastric mucosal lesion occuring after an acute medical crisis or trauma, such as sepsis or a head injurt
Main Manifestation of Stress Ulcers
Bleeding caused by gastric erosion
Peptic Ulcer
Mucosal lesion of the stomach or duodenum
Peptic Ulcer Disease
Results when mucosal defenses become impaired and no longer protect the epithelium from the effects of acid and pepsin
Symptoms - Pain after eating, belching
Treatment - Antibiotics for H. pylori, PPIs, Antacids, Histamine2 Antagonists
What are gastric and duodenal ulcers most commonly caused by?
H. pylori infections
Carafate
Binds with bile acids and pepsins to protect the stomach mucousa
Can you take aspirin and pepto bismol together?
No, it can cause an aspirin overdose and thin our your blood
A life threatening acute inflammation and infection of the visceral/parietal peritoneum and endothelial lining of the abdominal cavity is called what?
Peritonitis
Gastroenteritis
A very common health problem worldwide that causes diarrhea and/or vomiting as a result of inflammation of the mucous membranes of the stomach and intestinal tract
Four F’s of Gall Stones
Female
Forty
Fat
Fertile
How to Calculate BMI
Weight in lbs. divided by height in inches squared x703
TEN
Total Enteral Nutrition
Patients cannot meet the desired outcomes of adequate nutrition via their usual oral intake because of increased metabolic demands or a decreased ability to eat.
TPN
Total Parenteral Nutrition
Delivered through access to central veins, usually through a PICC line or the subclavian or internal jugular veins.
Cholecystitis
Inflammation of the gallblader
Can be acute or chronic
Two Types of Acute cholecystits
Calculous and Acalculous
Acalculous Cholecystitis
Inflammation of the gallbladder occurring in the absence of gall stones
Typically associated with biliary stasis cause by any condition that affects the regular filling or empyting of the gallbladder
Calculous Cholecystitis
Inflammation of the gallbladder usually following and created by obstruction of the cystic duct by a stone (calculus)
Chronic Cholecystitis
Results when repeated episodes of cystic duct obstruction cause chronic inflammation
Calculi are almost always present
Slow onset of symptoms which can include:
- Jaundice
- Clay colored stools
- Dark urine
Main Risk Factors for Developing Gallstones
Obesity
Type 2 Diabetes
Dyslipidemia
Insulin Resistance
Risk Factors for Cholecystitis
Women Aging American Indian, Mexican American, or Caucasian Obesity Rapid weight loss or prolonged fasting Increased serum cholesterol Women on HRT Family History Crohn's disease Gastric bypass surgery Sickle cell disease Glucose intolerance/ Pregnancy
Dyspepsia
Indigestion
Eructation
Belching
Blumberg’s Sign
Pain felt on abrupt release of steady pressure (rebound tenderness) over the site of abdominal pain
Diverticulitis
Inflammation of the diverticula
Cholestectomy
Gall bladder removal
- Do not eat foods high in fat
- Can resume normal diet
- Encourage an increase liquid intake
- Tell patient to ambulate if pain in shoulder blades; it will help the air to dissipate
What care can we provide to an excoriated perineum d/t gastroenteritis?
- Apply moisture barrier cream
- Use moist wipes when cleaning after toileting

C. Prealbumin 13 mg/dL
D. Serum albumin 3.5 g/dL
C. Prealbumin 13 mg/dL
What potential outcome does the nurse anticipate when administering TPN?
A. Infection
B. Dehydration
C. Hyperglycemia
D. Electrolyte imbalance
C. Hyperglycemia
The patient is ordered daily multiple vitamins with zinc and iron supplements. Which interventions promote oral nutrition intake? Select all that apply.
A. Having a UAP feed the patient
B. Providing mouth care before each meal
C. Placing a small-bore nasoduodenal tube
D. Assisting the patient to sit up in a chair
E. Ordering foods that the patient likes to eat
B. Providing mouth care before each meal
D. Assisting the patient to sit up in a chair

Methods of Administering TEN
Nasal tubes (short term):
- Nasoenteric tube
- Nasogastric tube
- Nasoduodenal tube
Enterostomal feeding tubes (long term):
- Gastrostomy
- Percutaneous endoscopic gastrostomy (PEG)
- Jejunostomy
What are the two most common electrolyte imbalances associated with TEN?
Hyperkalemia and hypernatremia

Caused by food entering the small intestine instead of the stomach after gastric bypass
Symptoms of Dumping Syndrome
Tachycardia
Nausea
Diarrhea
Abdominal cramping
If someone comes into the doctors office and they have lost 40 lbs since the last visit, what should the nurse do?
- Ask if intentional
- Ask why
- Ask if they are experiencing dysphagia
- Ask if they experience pain when they eat
- Are they able to tolerate the food that they are able to eat
- Possibility of cancer
When performing a tube feeding using an NG, what would the nurse do?
- Raise the head of the bed at least 30 degrees to prevent a chance of aspiration
- Listen to lung sounds before and after
- Look for residual in the tube
- Make sure the tube is in its proper place
There are several patients on the unit with laboratory values that just came back. Which patient would you assist first?
A. Serum sodium of 138
B. Potassium of 2.6
C. Foul smelling diarrhea
D. Glucose of 138
B. Potassium of 2.6
What would you teach to a patient that goes on frequent diet?
- Portion control
- Low carbs
- Eat when stressed or bored
- Find out psychological influences
How would you promote better nutrition in older adults?
- Find what foods they like
- Help with resources getting proper food
- Check dentures, make sure they are in place and they fit well
- Do not interrupt them a lot – may get distracted easily and forget to eat the rest of their food
- Can’t see food
- Noise can be too distracting
When you are doing an NG tube and it has become occluded, what are you going to do?
- Always want to try flushing it first to make sure there is patency
- Do not crush all meds together and administer them because they can clog the tube
- Administer each med separately and flush in between each
- Ask if meds can be in a liquid form
- Flush tube with 30 - 50 mL of water
If you are going to have a nurse’s aide feed your patient, what are some things that you would tell the aide?
- How much of their food they normally eat
- Any restrictions
- Small bites
- Sit upright
- Glasses or dentures?
- Move urinal or bed pan if given food tray
- Warm food warm, cold food cold
- Make it feel like a normal setting
- Alternate bites of food with sips of water
- Sit with patient if they are okay with it
In community hospitals that don’t typically care for bariatric patients, what are some possible limitations of care?
- Are there are enough resources to take care of the patient?
- Is there enough staff on hand to transfer or move the patient when needed?
If you are in a hospital that does not have a bariatric bed but there is a bariatric patient that needs admitted, what could be hazardous to their health?
The bed would be too small and would limit movement on the bed.
Side rails might not be able to go up which could increase the risk for falls.
If the side rails are able to go up, they may cause the bed to be a “tight fit” for the patient and could potentially cause pressure ulcers.
