A patient has a pressure sore on the back of her right hip and the bone is exposed. This pressure sore is in?

Appeared in: IGNOU PB Bsc Nsg Entrance-2017

Explanation

A Stage IV pressure injury is defined by full-thickness skin and tissue loss where underlying structures such as bone, tendon, or muscle are exposed and directly palpable.
The patient's pressure sore with an exposed bone on the hip fits the exact definition of a Stage IV ulcer.
This stage signifies the most severe level of tissue destruction from prolonged pressure and shear.

Option A: Stage I involves intact skin with non-blanchable redness. The patient's skin is broken with bone exposed, which is far more severe.
Option B: Stage II is a partial-thickness wound, like a shallow ulcer or blister, where only the dermis is exposed. It does not involve tissue loss down to the bone.
Option C: Stage III is a full-thickness wound where subcutaneous fat is visible, but bone, tendon, or muscle are specifically NOT exposed. The key differentiator is the absence of exposed deep structures.

Clinical Relevance

Nursing practice connection: Use the key finding related to Pressure Ulcer Staging to guide bedside assessment, documentation, and the next nursing action.
A Stage IV pressure ulcer is a serious medical condition that significantly increases the risk of systemic infection (sepsis) and osteomyelitis (bone infection), which can be life-threatening.
Nurses must perform meticulous wound care, ensure adequate nutritional support (especially protein), and implement aggressive pressure-relief strategies to promote healing and prevent further breakdown.
What if? If the wound was covered by slough or eschar (dead tissue) so the base could not be seen, it would be classified as an 'Unstageable' pressure injury until debrided.

How to Approach the Question

First, identify the most critical clinical finding described in the question stem. In this case, it is 'the bone is exposed'.
Next, recall the standard classification system for pressure injuries (Stages I-IV).
Systematically compare the key finding with the definition of each stage.
Stage I involves intact, red skin.
Stage II involves partial skin loss (shallow ulcer/blister).
Stage III involves full skin loss with visible fat, but no exposed bone/muscle.

Concept Tested & Keywords

Concept Tested: Pressure Ulcer Staging
Stem keywords: pressure sore, right hip, bone is exposed
Lead-in keywords: is in
Clinical cues: The cue 'bone is exposed' is the definitive sign for staging this pressure injury.
