Q

Normal fxn of liver

A

Filtration of blood from stomach, spleen, pancreas, intestine, manufactures & secretes bile, manufacture of fibrinogen, prothrombin, heparin, vitamin A, immunoglobulins, storage of vitamins, metabolism of carbohydrates, fats, proteins, drugs, alcohol, and hormones, aids in destruction of aging RBC, and regulation of blood volume by storing up to 400ml of blood.

Q

Cirrhosis

A

Characterized by widespread fibrotic (scarred) bands of connective tissue. This changes the liver’s normal makeup and its associated cellular regulation. Livers become nodular; blood and lymph flow are impaired. Inflammation destroys hepatocytes.

Q

Hypovolemic shock review

A

Abnormally decreased volume of circulating fluid causing peripheral circulatory failure that endangers vital organs. The brain, heart, kidneys are particularly vulnerable. Tachycardia is an early sign of compensation for excessive blood loss. Tachycardia, tachypnea, BP normal initially, decrease or narrowing in pulse pressure (difference between systolic and diastolic), elevated BP can occur initially until compensatory mechanisms fail. Acidosis with vasodilation and decreased BP, increased bleeding, decreased circulating volume, and subsequent organ death.

Q

A 59-year-old patient with a history of alcohol abuse spanning 15 years has been diagnosed with cirrhosis. The patient will be undergoing abdominal paracentesis today. Which assessment finding alerts the nurse that the paracentesis has been successful?

a. Decrease in post-procedure weight
b. No residual obtained during procedure
c. Substantial decrease in blood pressure
d. Immediate sensation of a need to urinate

A

Answer A

Weight should decrease as fluid is drained from the abdominal cavity.
A substantial decrease in blood pressure can indicate shock. Residual should be obtained during the procedure. The patient should not feel a sensation or need to urinate, because a primary safety measure is to have the patient void right before the procedure to avoid injury to the bladder during the procedure.

97
Q

A

Lactose breath test
Lactose tolerance test

98
Q

Lactose intolerance therapy

A

Nonprescription lactose enzymes
Yogurt, calcium supplements
Vitamin D, riboflavin, protein supplements

99
Q

Lactose intolerance nutrition management

A

Lactose-free or reduced-lactose diet, no milk, milk products for some patients, milk pretreated with lactose can be used

100
Q

Lactose intolerance nursing care

A

Provide education, support, discuss sources of lactose, suggest trial of lactose-treated milk, lactose enzyme supplements, emphasize importance of obtaining proteins, calcium from other sources

101
Q

Short bowel syndrome

A

May result from small bowel resection, tumors, infarction of mucosa, incarcerated hernias, crohn disease, trauma, enteropathy from radiation therapy, affects absorption of water, nutrients, vitamins, minerals, severity depends on amount of bowel resected, increased risk for kidney stones, gallstones

102
Q

Short bowel syndrome s/s

A

Severity depends on total amount of bowel resected, which portions of bowel removed

103
Q

Short bowel syndrome management

A

Management focuses on alleviating manifestations, multivitamins, mineral supplementation, antidiarrheal medications, proton pump inhibitor, frequent, small, high-kilocalorie, high-protein feedings, total parenteral nutrition (TPN) for severe manifestations, monitor
vital signs, input and output (I&O), daily weights, nutritional status , skin turgor, mucous membranes

104
Q

Diarrhea nursing care

A

Document number, character of stools, limit lactose intake, provide skin care of perianal region

105
Q

Short bowel syndrome teaching

A

Instruct about diet, medication regimen, stress adequate fluid intake, discuss need for frequent weight monitoring, reporting changes, refer to dietitian or counselor, patient manages disorder on day-to-day basis

106
Q

Malabsorption disorders in infants and children: celiac disease

A

Irritability, behavioral issues, bloating, gas, diarrhea, vomiting, skin rashes
Decreased appetite, poor weight gain → failure to thrive, delayed growth/puberty, weak bones
Age-appropriate teaching important

107
Q

Malabsorption disorders in infants and children: lactose intolerance

A

Primary lactose deficiency: rare hereditary condition, infants require special lactose-free formula
Secondary lactose deficiency: celiac or Crohn disease, GI tract infection. Resolves with treatment of causing disorder, dietary changes, supplements

108
Q

Malabsorption disorders in infants and children: short bowel syndrome

A

Surgery for necrotizing colitis
Diarrhea, bloating, poor appetite, inability to gain weight
Prone to dehydration, vitamin, mineral, electrolyte imbalances

109
Q

Malabsorption disorders in pregnant women: Celiac disease

A

Female infertility, amenorrhea
Poor pregnancy outcome, intrauterine growth restriction
Increased risk for miscarriage, stillbirth, perinatal morbidity
Testing at-risk patients, diet restrictions

110
Q

Malabsorption disorders in pregnant women:
Lactose intolerance

A

Body’s ability to digest lactose may improve during pregnancy
If symptoms persist during pregnancy, focus on consuming other sources of protein
Calcium supplements, lactose-free products

111
Q

Malabsorption disorders in older adults: Celiac disease

A

Underdiagnosed due to less severe symptoms, similarity of symptoms to other age-related changes
Increased risk of malnutrition, poor bone health
Gluten-free diet may be problematic
Resistance to dietary changes
Gluten in medications

112
Q

Malabsorption disorders in older adults: lactose intolerance

A

Normal decline in lactose → increasing lactose intolerance
Dietary management
Calcium supplementatio

113
Q

Malabsorption disorders in older adults: short bowel syndrome

A

Normal aging process may decrease GI function, increasing severity of syndrome
Medication may affect body’s ability to absorb nutrients, especially with short bowel syndrome

114
Q

Pyloric stenosis

A

Narrowing of pyloric orifice that prevents food in stomach from passing into duodenum. Digestion and absorption impaired, causing dehydration, malnutrition. Affects newborns in first month, rare in adults

115
Q

Pyloric stenosis risk factors

A

May have genetic factor, more common in males than females, antibiotics in late pregnancy or first few weeks of life

116
Q

Pyloric stenosis s/s

A

Symptoms evident 3–6 weeks after birth
Projectile vomiting as stenosis worsens
Vomitus may contain blood
Persistent hunger
Peristaltic wave across abdomen
Leads to dehydration, malnutrition
Changes in stool
Failure to gain weight, may lose weight

117
Q

Pyloric stenosis diagnostic tests

A

Abdominal ultrasound
Upper gastrointestinal (GI) study
Blood tests

118
Q

Surgery for pyloric stenosis

A

Surgery is [erformed when fluid, electrolyte balance restored, open or laparoscopic pyloromyotomy, good prognosis

119
Q

Pyloric stenosis in adults

A

Primary: no apparent cause
Secondary: result of other GI problems
Often long history of digestive disorders
Most common in middle-aged men
Individuals who had pyloric stenosis as infants may be at increased risk
