Flashcards.

WHAT IS IT?

This card lists the warning signs of cancer and the stages of cancer. The warning signs use the word CAUTION as a memory aid.

WARNING SIGNS OF CANCER (CAUTION)

• •Change in bowel pattern
• •A sore that does not heal
• •Unusual bleeding
• •Thickening of the breast, testicle, or skin
• •Indigestion
• •Obvious change in a mole
• •Nagging cough

CANCER STAGING

• •Stage 0: carcinoma in situ
• •Stage I: local tumor growth
• •Stage II: limited spreading
• •Stage III: regional spreading
• •Stage IV: metastasis to other organs

WHAT IS IT?

Burn staging classifies how deep a burn goes into the skin and tissue.

TABLE

• •First degree -> Reddened, painful, intact skin
• •Second degree -> Partial thickness, broken skin, pain, pink/red, blisters
• •Third degree -> Full thickness, often painless, white/black eschar (dead tissue)
• •Fourth degree -> Muscle and/or bone exposed; common in electrical burns

WHAT IS IT?

This is a decision tree to sort congenital heart defects (heart defects present at birth). It splits defects first by whether cyanosis (bluish skin from low oxygen) is present, then by vascularity (lung blood flow) and signs of cardiac enlargement.

DECISION TREE

No cyanosis, with cardiac enlargement and normal/altered vascularity:

• •Patent ductus arteriosus (PDA)
• •Aortic stenosis
• •Pulmonic stenosis
• •Coarctation of the aorta

Cyanosis present:

• •Transposition of the great arteries (TGA)
• •Truncus arteriosus
• •TAPVC (total anomalous pulmonary venous connection)
• •Tricuspid atresia
• •Single ventricle
• •Ebstein's anomaly
• •Pulmonic atresia
• •Tetralogy of Fallot
• •Atrial septal defect
• •Ventricular septal defect
• •[source decision-tree branches partly garbled, verify branch assignments at source]

WHAT IS IT?

Gestational diabetes is high blood sugar during pregnancy. Increased weight and pregnancy hormones cause insulin resistance, which raises blood sugar. If the mother has high blood sugar, glucose crosses the placenta to the baby. The baby's body then makes more insulin, causing excessive growth.

Quick Concept: Maternal insulin does not cross the placenta, only glucose does, so the fetus responds to the mother's high sugar by making its own extra insulin.

ASSESSMENT

Maternal changes:

• •1st trimester: insulin needs are reduced
• •2nd and 3rd trimester: insulin resistance occurs as hormones increase, so insulin needs increase
• •Right after the placenta delivers: hormones and insulin requirements decrease; gestational diabetics should no longer need insulin or diet management after delivery

Newborn changes:

• •The baby grows faster and larger, but its function still reflects age, not size
• •Macrosomic (large baby) = 4000 g

Assessments:

• •Screen for glucose and protein in urine at regular prenatal visits (glucosuria and ketonuria)
• •Check blood sugar between 24 and 28 weeks with glucola testing
• •High-risk patients may be screened at the beginning of pregnancy

MANAGEMENT

• •Ideal to control with diet and exercise
• •Monitor for typical diabetes mellitus (DM) complications (signs of infection, high blood pressure, edema, proteinuria)

WHAT IS IT?

Preeclampsia is a hypertensive (high blood pressure) disorder with a BP of 140/90, plus proteinuria (protein in the urine), occurring after 20 weeks of gestation (pregnancy). A woman may or may not have symptoms but will have elevated blood pressures and proteinuria.

Diagnostic criteria:

• •Proteinuria: over 300 mg in a 24-hour urine specimen, and a protein:creatinine ratio over 0.3
• •Blood pressure: 140/90 or more on two occasions 4 hours apart, OR a systolic of 160 mmHg or more, OR a diastolic of 90 mmHg or more. Both 140/90 and 160/90 are classified as preeclamptic hypertension.

ASSESSMENT

• •Sudden increase in edema (swelling) in the hands and face
• •Sudden weight gain from excess fluid retention
• •Complaints of headache, epigastric (upper-middle abdomen), or RUQ (right upper quadrant) pain
• •Vision changes: a serious symptom, from swelling and irritation of the brain and CNS (central nervous system)
• •Proteinuria: MUST be present to be preeclampsia

Fetal assessment:

• •Intrauterine growth restriction (IUGR): placental blood flow is not at its best

MANAGEMENT

• •Delivery of the baby is the only treatment
• •Magnesium sulfate is given prophylactically (preventively) for seizure prevention
• •Some antihypertensive (BP-lowering) drugs might be given to manage BP

WHAT IS IT?

Some infections during pregnancy are concerning because they can pass to the fetus (through the placenta or during delivery) and harm the newborn. The TORCH group is a helpful memory aid for these infections.

TORCH

• •T: Toxoplasmosis
• •O: Other (such as Group B strep, HIV, syphilis)
• •R: Rubella
• •C: Cytomegalovirus
• •H: Herpes simplex

DETAILS

Toxoplasmosis:

• •A parasitic disease passed to the mother while handling cat litter, undercooked or raw meat, or gardening; passed to the fetus through the placenta
• •The mother is usually asymptomatic but may have a rash or flu-like symptoms for a few weeks to months
• •Can cause fetal death, spontaneous abortion, and neurologic complications
• •Educate the mother to never change cat litter

Other (Group B strep):

• •All women are screened during the prenatal period by a vaginal swab at 35 to 37 weeks
• •All women have the bacteria; results depend on the amount colonized
• •Prophylactic antibiotics (penicillin or ampicillin) are given during labor to women who screen positive
• •The main cause of bacterial infections in newborns, which causes sepsis

Other (HIV):

• •Delivery by c-section to limit transmission
• •Infants are given antiretrovirals

Other (Syphilis):

• •Woman is given penicillin, and the fetus receives penicillin after delivery

Rubella:

• •Passed through the placenta
• •Most dangerous if the mother gets it in the first trimester
• •Can cause brain damage, hearing loss, miscarriage, stillbirth, and various congenital defects
• •Assess the mother's immunity by drawing a titer. If non-immune, vaccinate immediately after delivery because it is a live vaccine. The vaccine protects future pregnancies.

Cytomegalovirus (CMV):

• •A very common, asymptomatic virus passed through bodily fluids
• •Passed through the placenta or during delivery; can cause intrauterine growth restriction, seizures, blindness, hepatomegaly, splenomegaly, jaundice, hearing loss, microcephaly, and/or death

Herpes Simplex:

• •Passed during birth if active lesions are present; a c-section should be done with an active lesion to prevent transmission
• •Acyclovir may be given around 36 weeks to prevent an outbreak during labor and delivery
• •Can cause serious neonatal complications (death, neurologic issues, etc.)

WHAT IS IT?

The newborn physical exam is the first physical assessment after birth. It establishes a baseline. Assess for temperature stability and note all abnormalities.

Keep the baby warm:

• •Nursing interventions must maintain temperature stability

The intrauterine to extrauterine transition period has 3 phases:

• •Reactivity: most alert and the best feeding time, in the first hour
• •Decreased responsiveness: sleepy, in the second hour
• •Reactivity: a second reactivity phase, hours 2 to 6, alert

ASSESSMENT

General observations:

• •Newborns should have a flexed posture and coordinated movements
• •Count extremities, fingers, toes
• •Check for an anus; if not patent (open), do NOT feed; if no anus is found, this is an emergent surgery
• •In males, check that the urinary meatus (opening) is on the penis; hypospadias is when the meatus is on the under portion, and NO circumcision can be performed on these clients
• •Check for hip dysplasia using the Ortolani maneuver: rotate the thighs outward and feel for clicks at the hips; no clicking or crepitus is normal; any clicking or crepitus indicates hip dysplasia; also check by placing the infant prone and looking for symmetrical buttock creases, where symmetry indicates no dysplasia

Vital signs:

• •Some newborns may have slight, subtle tremors that can be normal or due to drug withdrawal, hypocalcemia, or hypoglycemia
• •Listen to the apical pulse for 1 full minute: 120 to 160 BPM resting is normal
• •Listen to respirations for 1 full minute: 30 to 60 RR is normal
• •Axillary (armpit) temperature: 97.8 to 99 F is normal

Head:

• •Measure head, weight, length
• •Fontanels (soft spots): anterior and posterior

Eyes:

• •Weak eye muscle
• •Newborns may have strabismus or disconjugate gaze (eyes not aligned)

Ears:

• •No pits or skin tags

Mouth:

• •Assess for an intact palate, no teeth

Chest:

• •Assess for clavicular (collarbone) fractures from birth
• •Breast tissue swelling might be observed
• •May note secretions from the nipple

Umbilical cord:

• •Assess for 2 arteries and 1 vein
• •Assess for meconium staining on the cord

• •[source fragment unclear, verify at source: source lists fontanel locations as anterior "back of the head" and posterior "top of the head," which appears reversed]

NURSING CONSIDERATIONS

Rho immune globulin:

• •Given by the IM (intramuscular) route at 28 weeks of gestation and again within 72 hours after delivery.
• •Also given within 72 hours after potential or actual exposure to Rh+ blood, and must be given with each subsequent exposure to Rh+ blood.

Other teaching:

• •Folic acid should be started 3 months before pregnancy; it decreases the incidence of neural tube defects.
• •Warfarin is teratogenic (causes birth defects), especially in the 1st trimester. Heparin is not. They cause the worst damage during the 1st trimester.

WHAT IS IT?

This card describes the four stages of labor.

TABLE

• •1st stage (Cervical dilation): begins with the onset of regular contractions and ends with complete dilation. Phases: Latent (0 to 3 cm), Active (4 to 7 cm), Transitional (8 to 10 cm)
• •2nd stage (Expulsion): begins with complete dilation and ends with delivery of the fetus
• •3rd stage (Placental): begins immediately after the fetus is born and ends when the placenta is delivered
• •4th stage (Maternal homeostatic stabilization): begins after delivery of the placenta and continues for 1 to 4 hours after delivery

WHAT IS IT?

Placenta previa is when the placenta covers or lies near the cervical opening. This card compares its signs with abruptio placentae (when the placenta separates from the uterine wall early).

PLACENTA PREVIA

• •Painless bright red vaginal bleeding
• •Soft uterus
• •Vaginal exams are contraindicated

ABRUPTIO PLACENTAE

• •Dark red vaginal bleeding
• •Uterine pain and/or tenderness
• •Uterine rigidity

WHAT IS IT?

This card matches fetal heart rate changes on the monitor to their likely cause.

MAPPINGS

• •Variable decelerations: cord compression
• •Early decelerations: head compression
• •Accelerations: okay (a reassuring sign)
• •Late decelerations: placental insufficiency
• •[source fragment unclear: source lists "late accelerations" but pairs it with placental insufficiency, which describes late decelerations; verify at source]

WHAT IS IT?

This card lists normal postpartum vital sign ranges and the findings that should be reported.

NORMAL RANGES

• •Temperature: may rise to 100.4 F during the first 24 hours postpartum because of the dehydrating effects of labor. Any higher elevation may be caused by infection and must be reported.
• •Heart rate: may decrease to 50 bpm (normal puerperal bradycardia); over 100 bpm may indicate excessive blood loss or infection.
• •Blood pressure: should be normal; suspect hypovolemia if it decreases.
• •Respiratory rate: rarely changes; if it increases significantly, suspect pulmonary embolism, uterine atony, or hemorrhage.

WHAT IS IT?

This card lists antibiotics to avoid during pregnancy and the harm each can cause. A memory phrase is "MCATO." It also notes the use of magnesium sulfate.

TABLE (MCATO)

• •Metronidazole: hepatic (liver) failure (relatively contraindicated)

WHAT IS IT?

This card lists common herbal supplements, their uses, and key teaching points.

TABLE (herb -> use and cautions)

• •St. John's Wort: treats depression/anxiety. Interacts with SSRIs. Causes sun sensitivity.
• •Garlic: lowers blood pressure and cholesterol. Interacts with aspirin and warfarin.
• •Ginkgo Biloba: improves memory. Thins the blood (do not take with aspirin or warfarin). Do not take with a history of seizures.
• •Echinacea: immune-boosting function. Can cause liver toxicity in renal (kidney) patients. Not effective with HIV.
• •Ginger: relieves nausea and vomiting. Do not take with a history of deep venous thrombosis. Interacts with blood thinners.
• •Black Cohosh: treats menopausal symptoms. Contraindicated in pregnancy (causes premature labor).
• •Kava Kava: treats insomnia and muscle pain. Associated with liver illnesses.
• •Saw Palmetto: used for prostate health. No specific patient teaching.

KEY POINT

WHAT IS IT?

Methylphenidate (Ritalin) is a medication used to treat ADHD (attention-deficit hyperactivity disorder).

NURSING CONSIDERATIONS

• •Assess for heart-related side effects and report them immediately
• •The child may need a drug holiday because the drug stunts growth

WHAT IS IT?

Erik Erikson described eight stages of social and emotional growth across the lifespan. Each stage has a central conflict the person must resolve. Success builds a healthy personality.

• •Trust vs. Mistrust (birth to 1 year): infant learns to trust caregivers who meet needs.
• •Autonomy vs. Shame and Doubt (1 to 3 years): toddler gains independence, wants to do things alone.
• •Initiative vs. Guilt (3 to 6 years): preschooler explores, plans, and takes initiative through play.
• •Industry vs. Inferiority (6 to 12 years): school age child masters skills and feels competent.
• •Identity vs. Role Confusion (12 to 18 years): adolescent forms a sense of self.
• •Intimacy vs. Isolation (young adult): forms close, committed relationships.
• •Generativity vs. Stagnation (middle adult): contributes to others and the next generation.
• •Integrity vs. Despair (older adult): reflects on life with a sense of acceptance.

WHAT IS IT?

Jean Piaget described four stages of how thinking develops in children. Each stage shows new ways of understanding the world.

• •Sensorimotor (birth to 2 years): learns through senses and movement. Develops object permanence (knows an object exists even when hidden).
• •Preoperational (2 to 7 years): uses symbols and language. Thinking is egocentric (sees the world only from own view). Magical thinking is common.
• •Concrete Operational (7 to 11 years): logical thinking about real, concrete things. Understands conservation (amount stays the same even if shape changes).
• •Formal Operational (11 years and up): abstract and hypothetical thinking. Can reason about ideas and possibilities.

Quick Concept: Sensory, Symbols, Sensible (concrete), Speculation (abstract).

WHAT IS IT?

The infant period is birth to 12 months. Motor and social skills appear in a predictable order. These are average ages and may vary.

• •Magical thinking and fear of bodily harm are common. Use simple, honest words during care.

WHAT IS IT?

School age is 6 to 12 years. Adolescence is 12 to 18 years. The focus shifts from family to peers and then to identity.

KEY POINTS

• •School age: enjoys rules, games, and collecting. Wants to feel competent and accepted by peers.
• •School age play is cooperative (organized, with rules and roles).
• •Adolescence: rapid physical growth and puberty. Peer group is very important.
