Acute Illness II Flashcards
What are the causes of nausea and vomiting?
-GI Tract-related (stimulation of visceral nerve), often gastroenteritis
-CNS disorders, often Vestibular disorders (motion sickness)
-Overeating
-Pregnancy
Symptoms and complications of nausea and vomiting:
-Pale skin, cold sweats, dizziness, headache, increased BP and HR
-Complications: Dehydration, electrolyte imbalances, aspiration, malnutrition, tears
How can motion sickness be treated?
With antihistamines, bc Histamine is one of the neurotransmitter involved in that pathway
What are the causes of diarrhea?
Diarrhea: increase in stool frequency, liquidity, weight, or volume
-often infectious diarrhea (gastroenteritis; viral, bacterial)
-travelers diarrhea
-Food-induced or Food intolerance (lactose)
Where to pay attention in patients with diarrhea?
-Dehydration, electrolyte imbalances
-Self-limiting, clears out itself
How to assess if diarrhea is self-treatable:
SCH
Symptoms: Severity of abdominal pain (it could also be due to injury or GI ulcer), Vomiting, or fever?; Signs of dehydration? Fluid and Food intake?
-Characteristics: Description of stool (color, consistency?) Blood?
Frequency and volume of diarrhea?
-History: Recent travel? What have you eaten? Happened before?
Medication? Pregnant? Diabetic or cardiovascular disease?
What causes diarrhea?
-Absorption
-Target of the drug: opioid receptor in the small intestine
What causes intestinal Gas?
-it is a disruption in the normal physiologic digestive process -> belching, flatulence
-Diet: carbs, oligosaccharides - vegetables, beans
-Carbohydrate malabsorption (lactase deficiency/lactose
intolerance, gluten intolerance (celiac disease))
-swallowing air
-intestinal flora altered
-drug-induced
-Symptoms: are often discomfort of abdomen -> MILD and often self-treatable
How to assess if intestinal gas is self-treatable:
SCHO
Symptoms: abdominal discomfort/pain? change in bowel function? Diarrhea? Constipation?
Characteristics: GI bleeding (dark, tarry stools), fatigue, unintentional weight loss
History: How often do symptoms occur?
Onset: Do symptoms correspond with any particular food
consumption? How long do symptoms persist?
Where does the gas in the stomach come from?
-200ml of gas in the GI tract
-Swallowedair
-Bacteria-producing
-metabolized diet, neutralization of acids in the small intestine
What are the causes of acute heartburn?
-a burning sensation in the stomach or behind the breastbone
-radiates up towards the neck and throat bc of acid reflux
-often bc of overeating and certain meals -> stimulating the trigger
-obesity
-pregnancy, the child pushing organs
-smoking and stress
-drug-induced
Symptoms of heartburn
Symptoms: Belching, bloating, nausea
-> when related to food, it will be depending on what and how much you have eaten (1hr after meal)
Which issue can also be interpreted as heart burn?
-heart attack, bc the pain is at the same location
-screen well!
Assess if heart burn is self-treatable:
Symptoms: pain on swallowing solid foods? unexplained weight loss? anemia or blood loss? Vomiting blood or passing black tarry stools? Nausea, vomiting, diarrhea?
Characteristics: Looking for severe symptoms -> refer
History: Duration: it could cause damage to the esophagus due to acid
Onset: Does it come from a certain food? How long do symptoms persist? Is it overnight?
Remitting factors: Has the patient tried any medication before?
Pathophysiology/cause of heartburn:
Low functionality of the lower esophageal sphincter, allowing the acid to go up the esophagus
-distention of the proximal stomach by food or gas
-positioning after eating (lying down)
-delayed gastric emptying due to overeating
How to evaluate dehydration:
-anyone with severe symptoms of dehydration needs to be referred and needs IV fluid
-increased heart rate, but low blood pressure bc there is not much blood flow
-mentally unconscious -> drinks poorly
-deep breath, dry tongue, sunken eyes
-check skin turgor: Severe dehydration = recoil in > 2 sec
