Q1 QUESTION 1 OF 100
Bones buffer acid by
CORRECT ANSWER
Releasing alkaline salts (calcium carbonate, calcium phosphate) into circulation.
RATIONALE
Bones act as a buffer by releasing alkaline salts like calcium carbonate and phosphate, which neutralize excess
hydrogen ions in the bloodstream and maintain pH homeostasis. This process leverages the large mineral reservoir
within bone tissue to mitigate metabolic acidosis.
Q2 QUESTION 2 OF 100
Strain
CORRECT ANSWER
injury to muscle or tendon - causes pain, swelling, and muscle weakness
RATIONALE
A strain is a musculoskeletal injury involving overstretching or tearing of muscle fibers or their attached tendons,
clinically manifesting as pain, edema, and impaired muscle function due to the disruption of contractile tissues. This
question assesses understanding of the definition and clinical presentation of a strain.
Q3 QUESTION 3 OF 100

,Sprain
CORRECT ANSWER
injury to a ligament, which connects bones to the joint
RATIONALE
A sprain is damage to a ligament, the fibrous connective tissue that stabilizes a joint by connecting bone to bone.
This injury results from overstretching or tearing of these ligaments, often due to sudden twisting or impact.
Q4 QUESTION 4 OF 100
NHL (Non-Hodgkin Lymphoma) Risk Factors
CORRECT ANSWER
Immunosuppression, prior radiation, autoimmune disease.
RATIONALE
Immunosuppression from conditions like HIV or organ transplantation, prior radiation therapy, and certain
autoimmune diseases are well-established risk factors for the development of NHL due to their impact on immune
surveillance and cellular regulation. The key underlying concept is the link between impaired immune function and
oncogenesis.
Q5 QUESTION 5 OF 100
Superficial Burn (1st degree)
CORRECT ANSWER
only epidermis is damaged, skin is red and swollen
RATIONALE
Superficial burns involve only the epidermis, manifesting as erythema and edema due to inflammatory mediators
released from damaged epidermal cells. This damage spares the dermis and underlying tissues.
Q6 QUESTION 6 OF 100
Page 3
, Partial thickness (2nd degree)
CORRECT ANSWER
epidermis= destroyed, dermis=damaged. blistering and blanching present; pain present
RATIONALE
Partial-thickness burns destroy the epidermis and damage the dermis, leading to blistering, blanching, and pain due
to exposed nerve endings. This injury pattern defines the depth of damage characteristic of a second-degree burn.
Q7 QUESTION 7 OF 100
Full thickness burn (3rd degree)
CORRECT ANSWER
all layers are damaged, charred black or areas are dry and white. No pain.
RATIONALE
Full-thickness burns destroy the epidermis and dermis, damaging nerve endings and subcutaneous tissue, resulting
in a dry, leathery appearance and absence of pain due to complete tissue destruction. This represents destruction of
all dermal and epidermal layers.
Q8 QUESTION 8 OF 100
Rhabdomyolysis
CORRECT ANSWER
dissolution of striated muscle (caused by trauma, extreme exertion, or drug toxicity; in severe cases renal
failure can result)
RATIONALE
Rhabdomyolysis describes the rapid breakdown of skeletal muscle fibers, releasing myoglobin and other
intracellular contents into the blood, which can precipitate acute kidney injury. This pathological process is
triggered by various stressors including severe trauma, extreme physical exertion, or certain pharmacologic agents.
