A nurse cares for a client with a respiratory rate of 6 breaths per minute and an oxygen saturation of 71% What action should the nurse take first?

Rationale for correct choices

• Non-blanchable erythema: Stage 1 pressure injuries are characterized by intact skin with non-blanchable redness over a bony prominence. The redness does not turn white when pressure is applied, indicating underlying tissue compromise. Early identification at this stage allows for interventions to prevent progression.

• Stage 1: A Stage 1 pressure injury involves superficial skin changes without partial or full-thickness tissue loss. The classification helps guide preventive measures, such as repositioning, pressure-relieving devices, and skin protection strategies.

Rationale for incorrect choices

• Partial-thickness loss of dermis: Partial-thickness loss of dermis corresponds to a Stage 2 pressure injury, not Stage 1. This stage presents as a shallow open ulcer or blister, indicating more advanced skin breakdown than non-blanchable erythema.

• Full-thickness tissue loss: Full-thickness tissue loss is seen in Stage 3 or Stage 4 pressure injuries. These involve deeper tissue layers, potentially including fat, muscle, or bone, and are more severe than Stage 1 injuries.

• Stage 4: Stage 4 pressure injuries involve extensive tissue damage to muscle, bone, or supporting structures. Non-blanchable erythema alone does not indicate this severity.

• Unstageable: Unstageable pressure injuries occur when the base of the wound is obscured by slough or eschar, making accurate staging impossible. Non-blanchable erythema is visible and can be staged as Stage 1.

A. Kussmaul respirations: These are deep, rapid, and labored respirations typically associated with metabolic acidosis, such as diabetic ketoacidosis. They do not include alternating periods of apnea and hyperventilation, so they do not match the described pattern.

B. Cheyne-Stokes respirations: This breathing pattern is characterized by cyclic periods of increasing and decreasing depth of respiration, followed by temporary apnea. It commonly occurs in clients with advanced heart failure, neurological injury, or nearing end-of-life, making it consistent with hospice clients exhibiting irregular breathing.

C. Agonal breathing: Agonal respirations are irregular, gasping breaths often seen in severe hypoxia or near death. They are typically ineffective for gas exchange and not part of a regular cyclical pattern.

D. Biot's respirations: Biot’s respirations consist of groups of quick, shallow breaths followed by irregular pauses. They are usually associated with increased intracranial pressure or medullary damage rather than end-of-life breathing patterns.
