QUESTION
What does the ABCDEF mnemonic represent when assessing skin lesions?
CORRECT ANS: Asymmetry, border irregularity, color variation, diameter greater than
6mm, elevation/evolution, funny looking
EXPERT RATIONALE
The ABCDEF mnemonic is a widely used screening tool for assessing skin lesions and
identifying potential melanomas. Asymmetry indicates that one half of the lesion does
not match the other half. Border irregularity refers to ragged, blurred, or notched
borders. Color variation means the lesion has multiple colors or uneven pigmentation.
Diameter greater than 6 mm (about the size of a pencil eraser) is concerning, though
melanomas can be smaller. Elevation or evolution refers to any change in the lesion over
time, including growth or changes in shape, color, or symptoms. "Funny looking" is a
catch-all term for any lesion that appears unusual or different from other moles. This
screening tool is essential for early detection of skin cancer, which is highly treatable
when identified early.
,QUESTION
What are the physiological changes associated with acute pain responses?
CORRECT ANS: Tachycardia, elevated blood pressure, increased cardiac output, hypoxia,
hypoventilation, atelectasis, decreased cough, nausea, vomiting, ileus, oliguria, urinary
retention, spasm, joint stiffness, increased adrenergic activity, fear, anxiety, fatigue,
impaired immunity, wound healing
EXPERT RATIONALE
Acute pain triggers a complex cascade of physiological responses throughout the body.
The cardiovascular system responds with tachycardia, elevated blood pressure, and
increased cardiac output due to sympathetic nervous system activation. Pulmonary
effects include hypoventilation, hypoxia, atelectasis, and decreased cough reflex, which
can lead to respiratory complications. Gastrointestinal responses include nausea,
vomiting, and ileus (paralytic ileus). Renal effects manifest as oliguria and urinary
retention. Musculoskeletal responses include muscle spasm and joint stiffness. The
endocrine system releases catecholamines, increasing adrenergic activity. Central
nervous system responses include fear, anxiety, and fatigue. The immune system is
impaired, which compromises wound healing and increases susceptibility to infection.
Understanding these responses is crucial for comprehensive pain management.
QUESTION
How do you assess for clubbing of the nails, and what is the normal finding?
CORRECT ANS: Put nail beds back to back and view profile sign index. Normal is 160°.
Early clubbing is 180° and late clubbing is anything less than 160°
,EXPERT RATIONALE
Clubbing is assessed using the profile sign test. The patient's nail beds are placed
backto-back, and the angle of the nail base is observed from a lateral view. A normal
nail base angle is approximately 160 degrees (the angle between the nail plate and the
proximal nail fold). Early clubbing presents with a loss of this angle, approaching 180
degrees, where the nail appears to float on the nail bed. Late clubbing shows an angle
greater than 180 degrees, with the nail becoming bulbous and the nail bed spongy.
Clubbing is a sign of chronic hypoxia and is associated with conditions such as chronic
obstructive pulmonary disease, lung cancer, congenital cyanotic heart disease, and
cystic fibrosis.
QUESTION
In which patient populations does clubbing occur?
CORRECT ANS: Smoking, lung cancer, pulmonary disease, congenital cyanotic heart
disease
EXPERT RATIONALE
Clubbing occurs in patients with chronic hypoxic conditions. The most common causes
include smoking-related lung diseases, lung cancer, chronic obstructive pulmonary
disease (COPD), interstitial lung disease, and congenital cyanotic heart disease. The
pathophysiology is believed to involve platelet-derived growth factors that cause
proliferation of connective tissue and increased vascularity in the distal phalanges.
Clubbing can also occur in some gastrointestinal and liver diseases, such as
inflammatory bowel disease and cirrhosis.
QUESTION
How do you detect pallor in a light-skinned patient?
, CORRECT ANS: Generalized pallor
EXPERT RATIONALE
In light-skinned patients, pallor is detected as a generalized paleness of the skin. The
skin loses its normal pink or rosy hue and appears noticeably lighter than usual. Pallor
results from decreased hematocrit, reduced peripheral perfusion, vasoconstriction,
anemia, or shock. Assessment should include observation of the face, lips, conjunctivae,
and nail beds, as these areas often show pallor more prominently. Pallor is a clinical sign
of decreased blood flow or reduced hemoglobin concentration.
QUESTION
How do you detect pallor in a dark-skinned patient?
CORRECT ANS: Ashen gray, dull, loss of glow, cool to palpation
EXPERT RATIONALE
In dark-skinned patients, pallor is more challenging to detect and presents as an ashen
gray or dull appearance with a loss of the skin's natural glow. The skin may feel cool to
palpation due to decreased perfusion. The conjunctivae, oral mucosa, and nail beds
should be examined, as these areas provide more reliable indicators of pallor. The
clinician should compare the patient's current skin appearance with their usual skin tone
and assess for any changes in skin color, warmth, and moisture.
QUESTION
How do you detect jaundice in a light-skinned patient?
CORRECT ANS: Yellow sclera, hard palate, skin, mucous membranes
