NURS 120 FINAL STUDY GUIDE
DIFFERENT TYPES OF ANEMIA
Hypovolemic anemia manifestations:
- Weakness
- Stupor; irritability
- Pale, cool, moist skin
- Hypotension
- Tachycardia (rapid, weak, thready pulse)
- Hypoxia (restlessness, dyspnea)
- Hypothermia
- Pain How does hypovolemic anemia occur?
- Abnormally low circulating blood volume due to blood loss. It can occur as a result of surgery or trauma. Nursing Interventions:
- Control bleeding
- Treat shock → O2 elevate lower extremities, keep warm
- Replace fluid → blood transfusion, plasma, dextran, NS (normal saline) or LR (lactated ringer’s)
- Monitor vital signs
- Put patient in a Trendelenburg position when they are going into shock o Modified Trendelenburg would be to lay them down on the floor and lift their legs up Iron deficiency anemia manifestations:
- Pallor
- Fatigue; weakness
- Dyspnea
- Angina
- Glossitis → burning tongue
- Headache
- Paresthesia Groups at risk for iron deficiency anemia :
- Premenopausal and pregnant women
- Lower-class socioeconomic background
- Older adults & individuals experiencing chronic blood loss Nursing Interventions:
- Check occult blood
- Ferrous sulfate 900 mg daily
- Oral or injection (Z track)
- Take with OJ for better absorption
- Monitor the stool if it’s black normal side effect
- Diet high in iron
- Oxygen-sparing activity ***FERROUS SULFATE TABLETS SHOULD BE TAKEN BETWEEN MEALS TO HELP ABSORB THE MEDICATION MORE EFFICIENTLY!! Which foods are high in iron?
- Beans & lentils -** Tofu - Dark leafy greens - Cashew - Whole-grain and enriched breads - Lean beef - Oysters - Chicken - Turkey *VITAMIN C ENHANCES THE BODY’S ABSORPTION OF IRON !! Pernicious anemia manifestations:
- Extreme weakness
- Dyspnea
- Fever
- Hypoxia
- Fatigue
- Weight loss
- Jaundice
- Pallor
- GI complaints
- Dysphagia
- Sore, burning tongue smooth & erythematous
- Neurological symptoms o Tingling of the hands and feet o Disorientation o Personality changes, behavior problems o Partial or total paralysis What is pernicious anemia?
- Absence of the intrinsic factor it is essential for the absorption of vitamin B12 (cyanobalmin) What is the Schilling’s Test?
- It is done to determine whether a person is able to absorb Vitamin B12 from the GI tract. If the radioactive B12 injection is not absorbed, then the patient is given the diagnosis of pernicious anemia.
APLASTIC ANEMIA manifestations:
- Pancytopenic low wbc, rbc, & platelets - Repeated infections w/ high fevers - Fatigue, weakness, malaise - Dyspnea - Palpitations - Bleeding tendencies Nursing Interventions for APLASTIC ANEMIA:
- Identify & remove cause
- Platelet transfusion for severe thrombocytopenia
- Splenectomy for hypersplenism
- Steroids and androgens
- Antithymocyte globulin
- Bone marrow transplant
- HIGH RISK FOR INFECTIONS What is Anemia?
- Disorder characterized by RBC & hemoglobin & hematocrit levels below normal range. → Primarily diagnosed with a CBC What causes anemia?
- Blood loss
- Impaired production of RBCs
- Increased destruction of RBCs
- Nutritional deficiencies Symptoms of Anemia: - Yellowing of the eyes - Palesness, coldness, yellowing of the skin - Dyspnea - Weakness - Black, tarry stool - Fatigue,headache, dizziness, **fainting
- Hypotension,** systolic murmur
- Palpitations, tachycardia - Chest pain, angina, heart attack - Spleen enlargement - Vertigo, anorexia, disorientation - Dyspepsia - Insomnia Later signs: Chest pain, MI, cardiac dilation, death. Nursing Management: - Oxygenation - Blood transfusions - Epoetin alfa and vitamin supplements **BLOOD TRANSFUSION DURING ANEMIA:
- How often should the nurse check the pt’s vital signs?** o Every 15 mins after the start of the transfusion, then every 1 hr during the transfusion process BLOOD TRANSFUSION PROCEDURE:
- Check vital signs before transfusion
- Insert an IV with a 19- gauge needle
- Prime the blood tubing with 0.9% NaCl to reduce risk of hemolysis
- Check the expiration date of the blood product with a 2 nd^ nurse
- Transfuse the blood product within 4 hrs after removing it from refrigeration INTRACRANIAL PRESSURE, HEADACHES, & SEIZURES EMBOLIC STROKE: - Occurs when an embolus lodges in and occludes a cerebral artery, resulting in infarction and edema. - Occurs rapidly, sudden onset - Rheumatic heart disease is a cause of embolic stroke in young to middled aged adults - Patient usually conscious although they may have a headache - Men are more likely to have them than women What causes ICP?
- Trauma, hydrocephalus, tumors, stroke, etc.
- Ex: a person who fell has a high risk of developing intracranial bleeding. *OCCURS SUDDENLY AND PROGRESSES RAPIDLY!!
- Avoid administration of morphine sulfate to prevent the occurrence of hypoxia
- Maintain body temperature
- Prevent shivering (shivering = increased ICP)
- Decrease environmental stimuli
- Monitor electrolyte levels and acid-base balance
- Monitor I&O - Limit fluid intake to 1200 ml/day
- Instruct client to avoid straining activities, such as coughing & sneezing
- NO LUMBAR PUNCTURE TESTS!! SUCTIONING IS CONTRAINDICATED!! MEDICATIONS FOR ICP - Corticosteroids DEXAMETHASONE for brain tumors, bacterial meningitis - Osmotic diuretic MANNITOL 25% reduces ICP o Given IV o S/E: HF, pulmonary edema, renal failure, dehydration, electrolyte imbalances (Na, K), phlebitis. - Anticonvulsants Phenytoin (DILANTIN) given for seizure. - Hypertonic saline reduces swelling and improves cerebral blood flow - Histamine CIMETIDINE or PPI PANTOPRAZOLE to prevent GI ulcers & bleeding Why is Mannitol given as a medication for patients with ICP?
- Decreases ICP by reducing the hematocrit and blood viscosity which then increases the CBF and O2 delivery.
- Mannitol creates a vascular osmotic gradient fluid moves from the tissues into the blood vessels reducing ICP b/c of the decrease in the total brain fluid content. CEREBRAL ANEURYSM MANIFESTATIONS:
- Headache and pain
- restlessness
