Answer 80

A

Atherosclerotic narrowing of the major epicardial coronary arteries. Blockages consisting of fats, platelets, other debris that form fatty streaks, fibrous plaques, and complicated lesions in large and medium sized arteries of the heart- changes lead to coronary artery narrowing. Narrowing leads to ischemic heart disease as a result of inadequate blood flow to the myocardium. CAD may manifest insidiously as angina pectoris or as an acute coronary syndrome (ACS) and lead to a myocardial infarction

Answer 81

A

Troponin I and T (cTnI, cTnT) rise 3 to 6 hours after onset of ischemic symptoms.
Myoglobin fraction of creatine kinase (CK-MB): rises 3 to 4 hours after onset of myocardial injury; peaks at 12 to 24 hours and remains elevated for 2 to 3 days; CK-MB adds little diagnostic value in assessment of possible ACS to troponin testing.
Myoglobin: early marker for myocardial necrosis; rises 2 hours after onset of myocardial necrosis, reaches peak at 1 to 4 hours, and remains elevated for 24 hours; myoglobin addslittle diagnostic value in assessment of possible ACS to troponin testing.
Fasting lipid profile, CBC with platelets, electrolytes, magnesium, BUN, serum creatinine, and glucose; international normalized ratio (INR) if anticoagulation contemplated; brain natriuretic peptide (BNP) is elevated in acute MI; may or may not indicate heart failure

Arterial occlusive disease

Answer 92

A

Check temperature, pulse, respirations and blood pressure
Inspect:
Inspect joints for swelling and warmth
Observe for signs of chorea
Conduct a dermal exam, especially the trunk and proximal aspects of the extremities. Individual lesions of erythema marginatum are evanescent, moving over the skin in wavy patterns. The lesions can develop and disappear in minutes, appearing to change shape while being examined
Complete an ear, nose, oral and throat exam. Evaluate tonsillopharyngeal erythema with or without exudates. Observe for beefy, red, swollen uvula.
Auscultate:
Auscultate heart. Note heart murmur, pericardial friction rub or effusion.
Auscultate all lungs fields. Note shortness of breath.
Palpate:
Palpate the neck lymph nodes
Palpate the extremities: apical and radial pulses
Palpate the abdomen
Neuromuscular examination for chorea
Have the patient stick out his or her tongue and note any movements
Have patient grip your hand – with chorea he or she will be unable to maintain a grip and rhythmical squeezing results
Observe for the spooning sign – a flexion a the wrist with finger extension when the hand is extended
Observe for the pronator sign – the palms turn outward when held above the head

Answer 93

A

Same as for CAD.
Aortic stenosis, hypertrophic cardiomyopathy; HTN; congenital heart defects.

Answer 94

Any skin changes/new growths that are of concern to the patientAsk about person & family history of skin cancerInquire regarding history of acute blistering sunburn, chronic sun exposure & use of sun protectionQuestion about prior radiation exposure, thermal injury, cigarette smoking (current & in past)

Answer 95

A

1◦ hyperlipidemia- specific inherited traits resulting in defects in lipid metabolism + transport
2◦ hyperlipidemia *(screen all patients w/the following conditions regardless of age): obesity, clinical evidence of atherosclerosis, AAA, Endocrine disorders (DM, Cushing’s, Metabolic Syndrome, hyper/hypoparathyroidism), renal disorders (CKD, uremia, nephrotic syndrome), hepatic disorders, immunologic disorders (lupus), stress, smokers , arterial hypertension, stigmata of dyslipidemia, Fam Hx of premature CVD (Men <55 and women <65 yrs in 1st degree relative), inflammatory disease, HIV, erectile dysfunction, COPD, HTN in pregnancy, alcohol, medications

CHD Risk Factors: (if ≥2, then calculate Framingham risk pg.543 uphold; use medCalc app or CCS app)
+: smoking, HTN (BP≥140/90 or on antihypertensive meds), low HDL (<40mg/dL), fam hx of premature CHD, age (men ≥45; women ≥55)
-: HDL cholesterol ≥60 mg/dL

Answer 96

A

Depends on the intensity of the burning agent and the amount of time in contact with skin
Superficial: minimal epithelial damage, no skin loss; slight erythema, blanches with pressure, can have sm. dry blisters – very painful
Superficial partial-thickness: all epidermis and upper dermis, but spare epidermal appendages (hair follicles, nails, sweat, and sebaceous glands, and sensory nerve cells); tender, erythematous, weeping skin, and clear blisters; blanches with pressure – painful
Deep partial-thickness: epidermis, dermis, and damage to the appendages – patchy areas of injury varying from superficial partial to full thickness; appear pale and waxy with patchy red areas and may have large blisters, no blanching – decreased pinprick sensation
Full-thickness: entire thickness of skin, including underlying subcutaneous fat –sensation absent
Deep: all above plus involves fat, muscle, and bone

Answer 97

A

ABCDEs tend to have greatest diagnostic accuracy when used in combination

Answer 98

A

Investigations
Goal: to determine underlying cardiac abnormality and ID possible aggravating factors, degree of ventricular impairment and type of cardiac dysfunction
Initial: 12-lead ECG

Labs
BNP (test of choice to dx HF)
CBC, serum glucose, electrolytes+ extended lytes
HbA1C
BUN, Creatinine
TSH
LFTs
Lipid profile
Urinalysis
CRP, troponin, CK, Iron, ferritin, albumin
Imaging
CXR
TTE (transthoracic echocardiogram) + doppler GOLD standard cardiac pump size ax
Stress test or Nonstress test if cannot complete treadmill

Answer 99

A

Atypical squamous cells originate in epidermis, proliferate & penetrate epidermal basement membrane, eventually expand to dermis

Answer 100

A

Same as for CAD.
Aortic stenosis, hypertrophic cardiomyopathy; congenital heart defects.

Answer 101

A

Investigations / Labs
Screening: Refer to CCS for screening guidelines
Lipid testing done non-fasting
-men and women ≥40 (consider earlier in ethnic groups at árisk (South Asian/First Nation)
-screen all pts who fit risk factors for 2◦hyperlipidemia regardless of age

For all:
-Hx and physical exam
-standard lipid panel (TC, LDL-C, HDL-C, TG)
-Non-HDL-C (will be calculated from profile)
-Glucose
-eGFR

Optional:
-ApoB
-Urine albumin:creatitine ratio (if eGFR <60 mL/min/1.73m2, HTN, or DM

*if pt has hx of triglyceride levels >4.5 mmol/L then measure lipid + lipoprotein levels fasting
*see CCS guidelines for secondary testing

Answer 102

A

Examine entire surface of skin for suspicious lesions
Use magnifying glass and cross-illumination to highlight subtle changes in elevation and other surface characteristics.
All pigmented lesions should be carefully evaluated
A hair dryer is helpful in examining the use scalp; use a cotton-tipped applicator to move hair away from scalp

Answer 103

A

Elderly and undernourished
Immunodeficiency and diabetes mellitus Chemotherapeutic agents
Exposure to accidental or intentional injury

Answer 104

A

Acute rheumatic fever is an autoimmune inflammatory process that occurs as sequelae of a Group A streptococcal (GAS) tonsillopharyngitis
Inflammatory disease due to antibody cross-reactivity following GAS (Group A streptococcal) infection
Is characterized by inflammatory lesions of the joints, heart, subcutaneous tissue and CNS

Answer 105

A

Unstable angina
Vascular: aortic dissection, pericarditis, myocarditis, myocardial infarction
Pulmonary: pleuritis, pulmonary embolism, pneumothorax
Gastroesophageal: gastric reflux, esophageal spasm, peptic ulcer
Musculoskeletal: costochondritis, arthritis, muscle strain, rib fracture

Answer 106

A

Acute coronary syndrome (ACS) is used as a clinical classification for both unstable angina and acute myocardial infarction (AMI) because both present with similar signs and symptoms. Unstable angina involves episodes of chest or arm discomfort severe, prolonged and occur at rest, however of not a sufficient severity to result in necrosis (infarction). AMI is a process with sufficient severity and duration to be considered an infarction-permanent myocardial damage.

Answer 107

A

Ankle-Brachial Index

Answer 108

A

Signs and symptoms develop gradually as the atheroma and narrowing extend in the vessels –typically silent until sclerosis, stenosis, thrombosis, aneurysm, or embolus develops.
Fatigue, mild angina on exertion, and intermittent claudication are often initial complaints.
Ask questions related to risk factors as hyperlipidemia, PVD, PAD, HTN, diabetes- are commonly associated conditions
Ask about chest pain at rest or on exertion, pressure or discomfort in the chest.
Ask about leg pain with exercise or at rest- to investigate for possible PAD (PAD is associated with atherosclerosis and increased rates of CVS ischemic events).
Assess for shortness of breath and may present as dyspnea, orthopnea.
Ask about weakness, tiredness, and reduced exertional capacity, dizziness and palpitations
