A nurse is caring for a client who had moderate sedation during a procedure. The client's airway is obstructing, and they have an oxygen saturation of 90%. Which of the following interventions is the first action the nurse should take?

Choice A rationale:

Using fingers to remove loose tissue is not an appropriate action for the nurse to take when providing hydrotherapy for a burn wound. This action can cause further trauma to the wound and increase the risk of infection.

Choice B rationale:

Opening small blisters to expose air is contraindicated in burn wound management. The blister roof provides a natural barrier against infection, and puncturing them increases the risk of infection and delays the healing process.

Choice C rationale:

The correct answer is to wash the burn with a mild soap. Cleaning the burn wound with mild soap and water helps remove debris and minimize the risk of infection without causing additional damage.

Choice D rationale:

Applying wet-to-dry dressings is an outdated and inappropriate practice for burn wound care. Wet-to-dry dressings can be painful, disrupt wound healing, and increase the risk of infection. Modern burn wound care focuses on maintaining a moist environment to support optimal healing.

Choice A rationale:

The client's ABG values show a pH of 7.48, PCO2 of 30 mm Hg, HCO3 of 24 mEq/L, and PaO2 of 85 mm Hg. The elevated pH and decreased PCO2 (respiratory component) suggest respiratory alkalosis. Respiratory alkalosis occurs when there is excessive ventilation, leading to a decrease in carbon dioxide levels (hypocapnia) and subsequent alkalosis.

Choice B rationale:

Respiratory acidosis is characterized by an elevated PCO2 and decreased pH. In this case, the client's PCO2 is decreased, indicating respiratory alkalosis rather than respiratory acidosis.

Choice C rationale:

Metabolic alkalosis is characterized by an elevated HCO3 (bicarbonate) level and an increased pH. The client's HCO3 level is within the normal range, making metabolic alkalosis an incorrect identification.

Choice D rationale:

Metabolic acidosis is characterized by a decreased HCO3 level and a decreased pH. The client's HCO3 level is within the normal range, ruling out metabolic acidosis as the acid-base imbalance in this case.
