Which condition can cause nociceptive pain?

A. Stage IV: This stage involves full-thickness skin and tissue loss with exposed fascia, muscle, tendon, ligament, or bone. The case description specifies only partial-thickness loss involving the epidermis and dermis. There is no mention of deep tissue exposure in Marcus.

B. Stage I: A stage I pressure injury is characterized by non-blanchable erythema of intact skin. The assessment of Marcus identifies a shallow open area, which indicates a break in skin integrity. Therefore, the injury has progressed beyond the initial stage of redness.

C. Stage II: This stage is defined by partial-thickness loss of the dermis, presenting as a shallow open ulcer with a red-pink wound bed. The absence of slough or bruising is consistent with this classification. Marcus's assessment findings perfectly align with these specific criteria.

D. Stage III: Stage III involves full-thickness skin loss where adipose tissue is visible in the ulcer. The description of Marcus's wound as a shallow open area confirms it has not penetrated the subcutaneous layer. It remains restricted to the upper cutaneous layers.

E. Deep Tissue Pressure Injury (DTPI): This injury presents as a localized area of persistent non-blanchable deep red, maroon, or purple discoloration. Marcus's wound bed is described as pink and open, which contradicts the intact, dark discoloration seen in DTPI. The mechanics of his injury are superficial.

A. Iliac crest: Asymmetry of the iliac crests often suggests a pelvic tilt associated with a lateral spinal curvature or leg-length discrepancy. During a scoliosis screening, the nurse observes the waistline for unevenness that may indicate a compensatory pelvic shift. It is a primary landmark for identifying truncal imbalance.

B. Temporomandibular joint: This joint facilitates mandibular movement for mastication and speech and is located in the facial skeleton. Its alignment is unrelated to the structural integrity or curvature of the vertebral column. Asymmetry here would suggest a dental or maxillofacial issue rather than scoliosis.

C. Interphalangeal joint: These joints are located within the fingers and are involved in fine motor tasks and grip. Their alignment has no clinical relevance to the assessment of spinal symmetry or the detection of adolescent idiopathic scoliosis. They are distant from the axial skeleton and its associated postural landmarks.

D. Scapula: An uneven or "winging" scapula is a classic sign of scoliosis, indicating a rib hump caused by vertebral rotation. When the student performs the Adam's Forward Bend Test, one shoulder blade may appear higher or more prominent than the other. This is a critical indicator of a three-dimensional spinal deformity.

E. Acromion process: Shoulder height inequality, observed at the acromion process, is often the first visible sign of an underlying spinal curve. One shoulder appearing higher than the other at rest suggests that the thoracic spine is not properly aligned. It is a standard anatomical reference point in postural screenings.
