Stages of shock

Initial- not many s/s, you have decent o2 to vital organs, you may see increase HR, slight increase in respiratory rate. Stable

Nonprogressive- decrease o2 to non vital organs. Cooler temp extremities. Decreased urinary output, HR elevated, change in BP, restless

Progressive: non vital organs getting no oxygen and vital organs becoming hypoxic. Mental status change, fatigue, impending sense of doom, elevated HR bigger decline in BP, decline urinary output.

Refractory: almost too late. Non vital and vital is anoxic too much cell death and tissue injury. Multiple organ failure.

68
Q

The most common causative agents are gram negative bacteria- multiple antibiotics, vasoconstrictors, and agents to enhance myocardial perfusion and contractility.
Blood replacement therapy. ABX IS PRIORITY

78
Q

Antigens: blood type A develop antigens for A.

Antibodies: Blood type A develop antibodies to people with blood type B.

ABO system: AB develops antigens for both with no antibodies. O develops antigens for O and has antibodies against A and B.

AB and A and B can take blood from type O.

O is universal donor.
AB can receive blood from anyone- universal recipient

People with negative RH factor need to receive blood from other negative people.

79
Q

Donor: giving blood

Recipient: getting blood

Directed donation: specific donations of blood

Autologous donation: donate your own blood to themself if your having a procedure

Blood preservation: store blood in a freezer for like 3 weeks on stock then it becomes bad blood.

80
Q

Transfusion responsibility

Have to get a consent prior
Review agency policy.
Verify prescription with another RN
get a blood typing for client
Use two identifiers for patients who receive transfusions and verify with another RN
Examine blood bag Label, attached bag, and requisition slip for ABO and Rh compatibility with the client
Check expiration date and time with another RN
Inspect blood for discoloration, gas bubbles, cloudiness

Blood ignitated within 30 minutes as it arrives to the floor

81
Q

Transfusion responsibilities

Administer the blood product using the filtered tubing to remove aggregates and possible contaminates

Unless directed otherwise infuse blood products only with IV normal saline solutions because some other IV solutions can cause hemolysis

Stay with patient for the first 15-30 minutes of the infusion because this time severe reactions occur

Infuse the blood product at the prescribed rate for the transfusion type to avoid the possible complication of fluid overload

Monitor vital signs at least as often as agency policy ab the patients condition indicated to identify early indications of adverse transfusion reactions

A

Normal Saline 0.9% is the only fluid you can run with the blood. Usually connected with a V tube. Prime tubing with blood before you get started.

82
Q

RBC transfusion: replaces cells lost from trauma or surgery

Platelet transfusions: given low platelet counts, active bleeding, schedule for invasive procedure

Plasma transfusions: replaced blood volume and clotting factors

Granulocyte (WBC) transfusions: given rarely to neutropenic clients

Massive transfusion protocol: given when H&H levels are low

83
Q

Transfusion reactions

Febrile- elevated temperature within first 2hr. Hold transfusion give NS and contact physician.

Hemolytic- damaging to blood cells. Fever, chills, low back pain, flushing, low bp, hr goes up- stop transfusion give NS and contact physician

Allergic- hives, wheezing, itching, flushing- stop infusion, flush with NS, give antihistamine usually prior to prevent this

Bacterial- something in the blood(contaminated) usually wheezing, low bp high HR, dyspnea. Stop blood, NS, call physician

A

Circulatory overload- sob, jugular vein distention, bounding pulse, increased HR and RR. Stop infusion and call physician

Transfusion associated graft versus host disease- rare, almost always fatal. Lymphocytes found in transfusion donor blood attack the host tissues and cells. Usually happens later then has reaction.

84
Q

Autologous blood transfusions

Collection and infusion of patients own blood

Eliminated compatibility problems

Reduces risk for transmitting blood borne disease

85

Risk factors: NSAID, pregnancy,
, obesity, age, apnea, NG tube

Contributing factors; spicy food, fried foods, tight clothing, caffeine, coffee, eating or drinking before bed, tobacco use

S/S: chest pain, reflux, pyrosis- heart burn, throat irritation, loss of tooth enamel

Medication: antacids- magnesium or calcium- kills off acid, proton pump inhibitors, end in azol. Histamine to antagonists- end in dine. For Frequent gerd.l

97
Q

Peptic ulcer disease

Cause: to much acid, organism called by h pylori.

Ulcer formation: acid produced will irritate intestinal lining causing ulcers

S/s gi bleeds are common, can lead to perforations or tears. Can cause peritonitis
Pyrosis-heart burn, tarry stools or melena. Coffee ground emesis.

Treatment is same as gerd. Antacid, PPI, histamine antagonist, mucosal Protectants like surfactant.

98
Q

Intestinal obstruction:

Occurs in the small (more common) or large intestine (sigmoid colon most common)

Can be partial or complete

Severity depends on the region if the bowel, degree of the occlusion, and the degree of vascular disruption.

99
Q

Types of intestinal obstruction

Non mechanical: usually related to paralytic lieus when post op and have an obstruction bc bowels are still asleep. Or a muscular disturbance like Parkinson’s or muscular dystrophy

Mechanical: physically blocked. Hernias, tumors or intussusception- where intestines start to telescope within itself. More common in children. Can resolve on its own. Volvulus- twisting of intestine

Complications: perforation- rupture. Requires surgery: and colostomy. And peritonitis- inflammation around stomach lining and worry for sepsis. Fever chills abdominal pain, bloating, decreased urinary output.

100
Q

S/S of small bowel obstruction:

Crampy abdominal pain (usually seen in small bowel obstruction)

Reflux, vomiting, if obstruction is complete.

Fecal smelling breath

Dehydration signs: thirst, drowsiness, malaise, acchiness, parched tongue, and mucous membranes, anorexia

101
Q

S/S of large bowel obstruction

Develop and progress slowly

Constipation may be the only symptom for months

Weakness, weight loss, and anorexia

Marked abdominal distention

Crampy lower abdominal pain.

102
Q

Physical assessment

Obstipation- small bowel, constipation with large

Abdominal distention with both

Peristaltic waves: small

Bobborygmi: increased bowel sounds proximal to obstruction. Usually abdominal scan to find obstruction

103
Q

Intestinal obstruction treatment

Main one is NG tubes-
IV fluid replacement

Surgical management:
Exploratory laparotomy- to look for specific cause like mechanical construction or tumor.

104
Q

NG tube insertion:

For measurements: NEX measurement- measure from nose to ear to xiphoid process and add an inch. Wrap tape around the end to now where to stop.

To confirm placement after initial x ray is done, a combination of three methods is combined.

  • measure the length of the exposed portion of the tube every shift and compare it with the original measurement. An increase in length of exposed tube may indicate dislodgment or a leaking or ruptured balloon if the tube has a balloon.
  • visually assess the color of the aspirate to help distinguish between gastric and intestinal placement.
  • measure the pH of aspirate, which is a more accurate method of confirming tube placement than measuring the exposed tube length or assessing tube aspirate
A

Have patient lean forward for better tube placement.
Ask client if they had any nasal injury.
Assess nares. Once you hit resistance have client swallow and it will guide to correct placement:
If shortness of breath or excessive coughing stop it could go into lungs.

105
Q

Patient teaching about NG tube:
Increased risk for hypokalemia

Discuss bowel regimen with patient, including avoiding laxative use, increasing fluids, and increasing fiber.

Teach personal care to a patient who has undergone surgery with an patient who has undergone surgery with a ileistomy or colostomy, and dietary changes to help reduce gas production.

106
Q

Colorectal cancer:

Colorectal- refers to colon and rectum, which together make up large intestine.

Most are are adenocarcinomas

Etiology: age >50 years
Heavy alcohol use, genetic predisposition, personal family history of cancer, familial adenomatous polyposis

Drinking increases risk

107
Q

With colorectal cancer:

Physical assessment: bleeding and change in stool (most common signs)

Psychosocial assessment:

Fecal occult blood test: usually two within 3 days.
Carcinoembryonic antigen; lab work to see if there is cancer markers in blood.

Sigmoidoscopy or colonoscopy biopsy is main to diagnose

108
Q

Treatment: prevent/control metastasis
Radiation, chemo, surgical management

Assist: assist with grieving process

Care: care coordination an transition management.

109
Q

Hep A: fecal oral transmission: contaminated food and water

Hep: B blood transmission, sex, infected blood

Hep C: blood transmitted, sex, needles

Hep D: coinfection with hep B.

Hep E is fecal oral and contaminated food and water

110
Q

Hepatitis treatment:

Vaccines for hep a and hep b.

Avoid contaminated food and water

111
Q

Heptatitis s/s

Flu like symptoms
Fatigue
Anorexia

Jaundice 

Dx: US and liver biopsy
And labs to see if antibodies are present
Liver function test: ALT AST are increased

112
Q

With hep A they will let it run its course usually give immunoglobulins and encourage use of vaccinations

B&D- antiviral meds
interferon to treat

113
Q

Hepatitis treatment diet

High calorie
High carb

Low protein diet

Small frequent meals
Promote hepatic rest
Avoid OTC meds and herbal supplements

114
Q

Pancreatic cancer:
Converts food to fuel and glucose regulations

Difficult to diagnose

Treatment has limited results

Low survival rate

Drug therapy: radiation or chemo, biliary stent insertion

S/S clots

115
Q

Surgical management for pancreatic cancer

Whipple: 5 year survive rate goes goes up by 20% they remove the head of the pancreas, dedunum, jejunum, and part of the stomach if not all. Gallbladder, common bile duct and some of the spleen.

NG given afterwards
TPN typically began

116
Q

Pancreatic cancer: whipple surgery complications

Hemorrhage or hypovolemic shock and hepatorenal failure.

Monitor labs and urinary output. And signs for hypovolemia

Monitor bowel sounds

Watch for hypokalemia bc of NG tube

Glucose monitoring

Monitor electrolytes and mental status

117

Chronic conditions/ illness

Constipation

Decreased appetite

Dentition drugs

Dry mouth

Failure to thrive impaired eyesight

Pain that is acute or peristant

Weight loss

118
Q

Psychosocial risk factors for under nutrition

Ability or inability to make their own meals due to functional decline, fatigue, or memory

Decrease in enjoyment of meals

Depression

119
Q

Administering total enteral nutrition

Nasoenteric tube is short term (NET)
Nasogastric the
Nasoduodenal and nasojejunal tube is what physician will place.

Enterostomal feedings tubes- long term

Gastrostomy performed
PEG and PEG/J
Physicians placed these

Verify placement before Feeding
Done with pH typically
Pull back contents and measure gastric residual for delayed emptying.
Most feedings are room temp, HOB 30 degrees or higher when feeding. If bolus only 30 to an hour after. Flush with water before and after feedings.
Flush tubs four to 6 hours

120
Q

Types of tube feedings

Bolus: you will just connect it and give the feeding and disconnect after flushed

Continuous: continuous on a feeding

Cyclic: faster than continuous and slower than a bolus and over a period of time.

121
Q

Complications of TEN

Priority is always safety

Obstructed clogged tube is most common prob

Tube misplacement, dislodgment

Abdominal distention and nausea vomiting

Fluid and electrolyte imbalance
Crackles or coughing you will stop feeding

Refeeding syndrome- body goes into starvation. Fatal shift in fluid and electrolyte. Decreased glucose and electrolyte. Mental status change, HTN, signs of HF

122
Q

Peripheral parenteral nutrition means there less than 10% of dextrose in the nutrition itself and is used when gI tract isn’t function. PPN can be by a peripheral vein.

Total parenteral nutrition TPN
Has greater than 10% dextrose and has to be given through central line or peripherally inserted catheter or PIC line.
* You can add insulin and heparin to prevent fibrin build up.

123
Q

Complications for routes for TPN administration

At risk for

Sepsis: wash hands before you use it, use sterile technique with dressing changes every 3-7 days. Mask on yourself and client. NewTubing every 24hours

Pneumothorax: watch for shortness of breath, inhale and exhale and one side not move, pain.

Embolism: most pic lines have occlusion to catheter so that’s why we use heparin sometimes. Turn them on left side to trendelinburg and use anticoagulants

124
Q

Monitoring TPN administration

Flow rate and tubing

Standard TPN blood work: electrolyte, urea, creatine, Ca, PO4, Alb, TG, glucose, ALP, AST, ALT, cholesterol, bilirubin, platelets, INR, PTT

Glucometer BID*

Patients weight daily

Intake and output

125
Q

TPN administration

Double check physicians orders with Tpn pharmacy labels

Document how client is tolerating and glucose level and vital signs

Aseptic technique for IV therapy

Clean ports with 2% chlorhexidine gluconate with alcohol wipes

126
Q

TPN administration

Always infuse TPN With an infusion pump

Change TPN tubing every 24 hours

Monitor for S/S of complications- back up banana bag so you can change to next one. If you don’t have one hang 10% dextrose and water until you get banana bag or TPN.. if you don’t hang something then you stop it it increases risk of hypoglycemic event

TPN room temp one hour prior to administration, no cracks in bag, if it has oily appearance or layer of fat then throw it out. If you discontinue TPN then do it slowly because to rebound hypoglycemia

127
Q

Hyperglycemia s/s nausea, thirst, blurred vision, headache, polyuria.

128

Calcium level 8-10

Affect brain kidney and Neuro status

129
Q

Bowel Elimination

Diet: increase fluid, fiber and wheat, fresh fruit, increase activity

Ostomies: stoma should be beefy red/pink color if it’s purple or black it’s not getting blood supply

Ostomy care: assess skin for irritation or breakdown. Empty bags when they are a half or 1/4 way full.
Assess stoma and discuss avoiding odorous foods that cause gas.

130
Q

right sided is fluid overload, like fluid backs up to abdomen, ankles, legs and left is when it backs up to your lungs
