Cardiovascular - Uworld Flashcards
Nitroprusside
Vasodilator
Used in hypertensive emergencies
Can begin to act within 1 minute and can produce a sudden drop in BP, so you must monitor BP very closely.
PAD
Arteries of extremities become atherosclerotic
Reduces tissue perfusion and causes ischemic pain in lower extremities with movement and exercise
What causes increased risk for PAD
HTN
Diabetes
Hyperlipidemia
Smoking
Normal PTT and PT levels
PTT = heparin
25-35 seconds
PT 11-16 sec
Normal platelet and hematocrit levels
PLT 150,000-400,000
Hematocrit
Female: 35-47%
Male: 41-50%
Infective endocarditis
Bacteria or infection that attaches to your heart.
Can cause life threatening complications such as stroke or Ischemia to the extremities
Ischemia
Inadequate blood supply to to an organ or part of the body
Cardiac Tamponade
S/S
Compression of the heart caused by fluid collecting in the sac surrounding the heart S/S include -Hypotension -Jugular Vein distention -Distant heart tones -Dyspnea, Tachypnea -Tachycardia
Pacemaker teaching
No MRI
Notify airport security when traveling
Do not place cell phones directly over
Carry a pacemaker identification card with you and wear medical bracelet
Take pulse daily
Do not raise arm above shoulder on pacemaker side until HCP says its okay to avoid dislodging
(Using microwaves is okay!)
Home management of PAD
Lower extremities when laying down or sitting. Promotes arterial blood flow
Engage in moderate exercise
Perform daily skin care such as lotion to prevent breakdown
Maintain mild warmth (socks and blankets, no heating pad)
Stop smoking
Avoid tight clothing and stress
Take prescribed medications
How to find MAP
(Systolic + (Diastolic x2))/ 3
Normal MAP is between 70-105
Map <60 indicates that vital organs are underperfused and can become ischemic
assessing Jugular vein distention
HOB 45 degree angle
What increases cervical cancer risk
Multiple sex partners
Previous STI’s
Smoking
HPV «< The must important risk factor
Diabetic Ketoacidosis and potassium
Insulin pushes potassium into the cell and out of the blood stream, so if someone is in ketoacidosis and receiving IV insulin, potassium will be given even if potassium levels are normal
Refeeding syndrome
When a malnourished client starts getting adequate nutrition, the body begins making more insulin and which causes electrolyte deficiencies
Rapid declines in phosphorus, potassium, and magnesium
PPN
Normal phosphorus levels
Normal magnesium levels
P: 2.4-4.4
M: 1.5-2.5
Estrogen therapy risk
Increased risk for blood clots (DVT)
Rheumatoid arthritis vs osteoarthritis vs gout vs ankylosing spondylitis
RA - Symmetrical pain and swelling usually affecting small joints of hands and feet (not spine! Just cervical spine). Morning joint stiffness lasting from 60 min to several hours
Osteoarthritis - Asymmetrical pain in weight bearing joints. Crepitus, especially in knee joints
ankylosing spondylitis - Low back pain and stiffness, worse in the morning and gets better
Gout - pain, swelling and redness of one or more extremity joints (typically the great toe)
Endovascular
“Inside the blood vessel”
Surgery where they cut small incisions to access the blood vessel with a catheter
Babinski sign
Normal is that the toes point downward
Indicates upper motor neuron lesion from damage to corticospinal tract
Kidney inflammation (Pyelonephritis) expected finding
costovertebral angle tenderness
Examination for skin cancer
ABCDE
A- Asymmetrical
B- Border irregularity
C- Color changes and variation
D- Diameter of 6mm or larger (pencil eraser)
E- Evolving (changing in shape, size, color)
Peripheral artery disease
OKAY to dangle feet over bed to relieve pain Characterized by: -hair loss -ulcers -gangrene -cool dry, shiny, skin -Intermittent claudication -decreased blood flow from atherosclerotic build up -Thick, brittle nails -Decreased wound healing
Ileal conduit
Take piece of ileum to make a stoma, used as a urinary diversion. Ureters are connected to create an external opening.
Underlying medical conditions that could lead to delirium
Medications (opioids, analgesics) Electrolyte embalances Hypoxia Acute infections (fever, positive cultures) Sleep deprivation Dehydration or Malnutrition Metabolic Disorders (hypoglycemia)
Two types of UTI’s
Cystitis (Lower UTI, bladder)
Pyelonephritis (Upper UTI, kidneys)
Cystitis
Lower UTI Characterized by -Inflammation of the bladder mucosa -burning -frequency -urgency -hematuria -suprapubic discomfort
Pyelonephritis
Upper UTI They become very ill Characterized by -nausea and vomiting -fever with chills -flank pain -Costovertebral angle tenderness -Septic if not treated
Carpal tunnel syndrome
Pain and paresthesia of the hand caused by median nerve compression
Can manage symptoms with wrist immobilization by wearing a splint
Genital herpes
- Avoid sexual contact with active lesions…. Barrier contraception is not sufficient with active lesions
- Keep the area clean and dry
- Maintain proper hand hygiene and avoid touching the lesions
- Use mild soap to clean… no perfumed soap or bubble baths
- Use sitz bath and oatmeal baths to provide comfort and relief from itching
Anaphylactic shock
Also need to administer steroid such as methylprednisolone
Cardiac tamponade
Compression of the heart caused by fluid collecting in the sac around the heart
Possible complication of acute pericarditis
LIFE THREATENING
Characterized by:
-Hypotension
-Muffled heart sounds
-Neck vein distention
Foods rich in iron
Eggs, meat, shellfish, green leafy vegetables, dried fruit, broccoli, dried beans, brown rice, oatmeal
Romberg test
Neurological exam
Pt stands with feet together. Asked to close eyes, ability to maintain balance is assessed.
If positive romberg test, pt will need assistance with ambulating
MRSA risk factors
Older adult Suppressed immunity Long history of ABX use Invasive tubes and lines Pt in ICU
Preferred IM administration site for children <7 mo
Vastus lateralis
Clozapine
Antipsychotic to treat schizophrenia
Associated with a risk of agranulocytosis (dangerously low WBC count)
-Must have periodic CBC while taking
-notify provider of fever or sore throat
Enteric Coated drugs
Barrier coating that dissolves at a slower rate
Mono
Viral infection… no ABX
