o Peripheral artery disease – Arteries that supply limbs narrow and reduce blood
flow. Associated with atherosclerosis and stiffness.
Risk factors:
Hyperlipidemia, smoking, hypertension, and diabetes.
Presentation:
Extremity ulceration.
Arterial: over toe joints, over the boney prominence of the
malleoli, the anterior shin, or at the base of the heel. -
Venous: malleoli (above the bony prominence) and over
the posterior calf.
Neuropathic: pressure points of the foot (plantar surface of
the foot over the metatarsal heads and the heel).
Claudication - pain, cramp or sense of fatigue
(reproducible discomfort of a defined group of muscles that
is caused by exercise and relieved with rest.) - Can occur
with buttock, hip, thigh, calf, foot pain (alone or in
combination).
Diagnosis:
ABI (Gold standard)- Ankle brachial index (ABI) is a simple test
that compares the blood pressure in the upper and lower limbs.
An ABI of ≤0.90 has a high degree of sensitivity and specificity
for a diagnosis of PAD
Treatment:
Reducing cardiovascular risk factors, such as smoking cessation,
exercise therapy and a healthy diet.
Pharmacological therapy, even revascularization may be indicated
in more severe cases.
Stable claudication: 70 to 80% - Worsening claudication: 10 to
20% - Critical (may lead to limb ischemia): 1 to 2%
o Varicose veins -
o Heart failure – Heart cannot pump blood adequately or only with high filling
pressures. Most common in L ventricle. Classified by ejection fraction. <40% is
reduced EF. 75-50% is WNL.
Presentation
Classic symptoms: dyspnea, fatigue, edema.
Additional symptoms
exercise intolerance, unintentional weight loss, recurrent
ventricular arrhythmias, hypotension, and signs of
inadequate perfusion.
Risk factors
Ischemia or infarction, uncontrolled hypertension, new onset or
uncontrolled atrial fibrillation, excessive tachycardia, pulmonary
embolism, uncontrolled diabetes, thyroid dysfunction, and
substance abuse
DX: No gold standard, based on supporting data.

device such as a pacemaker, immunocompromised patients and
persons who use IV drugs.

palms of the hand and soles of the feet, that are not painful.

o Dyslipidemia – Abnormality elevated cholesterol or lipids leading to
atherosclerosis cardiac disease.
TX: 1st line -STATINS (Contraindicated in pregnancy)
Improves liver’s ability to remove cholesterol from blood.
Indications – Atherosclerotic cardiac disease calculator for 10-year risk
Low risk less than 5%. 5-10% moderate risk.High risk 10% or
greater. Severe risk 20% or higher
DM w/out CVD risk factors– moderate statin therapy
DM w/ CVD risk factors – High intensity
LDL greater than 190 – statin. Less than use calc risk. 10%
risk + LDL 100 = statin therapy
High potency statins = Atorvastatin 40 & rosuvaststin 20
High risk/ established cardiac disease.
Moderate = Lova 40, prava 40, simva 20, fluva 40 atorva 10,
rosuva 5.
Low = Lova 20, prava 10, simva 10 fluva 20
LDL recheck aft 6-8 weeks of starting or changing. Increase as needed.
Once stable check Q12 months. Promote lifestyle.
Before starting STATIN
baseline liver panel/recheck 4-12 weeks.
TSH – hypothyroidism is potential cause of dyslipidemia.
Adverse reactions - Myopathy, rhabdomyolysis, acute renal failure,
hepatotoxicity, pancreatitis. STOP and restart once resolved.

o Epiglottitis Inflammation of the epiglottis - Most common bacterial cause is
Group A Streptococcus (GAS).
o Presentation:

important.

Kegels) - Continence pessaries - Bladder training
Stress, urgency and overflow incontinence.
UTI – 90% caused by Ecoli.
o Risks: poor hygiene, DM, immunocompromised, frequent sex, pregnancy,

Treatment: Beta-lactam (cephalexim, cefuroxime) 5-7 days.
Nitrofurantoin – avoid in pregnancy 1st tri or after 36 weeks. Avoid in
pyelonephritis. Trimethoprim/sulfamethoxazole(TMP/SMX) such as
Bactrim or Septra 3-5 days
o Complicated UTI
Systemic symptoms such as fever, chills, or costovertebral (CVA)
tenderness, male gender, poorly controlled diabetes, pregnancy, children,
elderly, immunocompromised, recurrent UTIs, presence of kidney stones
or an obstruction, of if there is an indwelling catheter in place7-10 days.

risk for resistance) -TMP/SMX (7 to 10 days)
o Diagnoses: Positive nitrates, WBCs and leukocytes
o Do not treat asymptomatic bacteriuria unless pt is pregnant.
Enuresis - “bed wetting”
o Hormonal: Under production of ADH. Can be DM symptom.

that are diuretics.

o Behavioral Treatment: reduce fluid intake, volume control (holding urine during
day to increase capacity), alarm setting/waking.
o Medication treatment: Not curable only treats symptoms. ADH increasing
medication. (Desmopressin, imipramine)
o Surgery
Renal insufficiency (failure)
o Inability of kidneys to perform excretion leading to retention of nitrogenous waste
products from blood.
o AKI
prerenal occurs secondary to reduction in extracellular volume or
reduction in circulating volume despite normal total fluid volume
(Cirrhosis, heart failure, sepsis). GFR decreases and BUN and creatinine
increase due to failure of adaptive mechanism in maintaining inter arterial
pressures through dilation of afferent arterioles and constriction of
efferent. (ARBS, ACE, NSAIDS, organ failures, hypotension)
Intrinsic- glomeruli, vasculature, or tubulointerstitial (
Post renal – obstruction of urinary flow (tumors, clots, stones etc.)
o CKD
Hyperfiltration and hypertrophy of viable nephrons leads to distortion of
glomeruli damage, poor filtration, and sclerosis. (DM, HTN,
glomerulonephritis, renal vascular disease, reflux, infections)
o Diagnoses: urinalysis, dipstick, microscopy, electrolytes, casts, CK, renal US,
cystoscopy, kidney biopsy.
o Treatment:
AKI
Treat underlying cause, risk of hyperkalemia, Flomax or alpha
blocker for obstruction. Review medications and stop nephrotoxic
eds, monitor input/output, daily weights.
Complications, including hyperkalemia, pulmonary edema, and
acidosis-all potential reasons to start dialysis.
CKD
Control HTN and DM, reduce proteinuria with ACE/ARBS they
slow progression.
CKD classified based on stage:
Stage 1: GFR greater than 90
Stage 2: 60 to 89
Stage 3: 30 to 59
Stage 4: 15 to 29
Stage 5: Less than 15
o End stage renal failure
Permanent and chronic terminal illness. Transplant or dialysis required.
