The nurse is caring for four clients:

• Client A, who has emphysema and whose oxygen saturation is 94% on room air;
• Client B, with a postoperative hemoglobin of 8.2 mg/dL (82 g/L);
• Client C, newly admitted with a potassium level of 3.8 mEq/L (3.8 mmol/L);
• Client D, scheduled for an appendectomy who has a white blood cell (WBC) count of 14,000 mm3 (14 x 109/L).

Which intervention should the nurse implement?Reference Range:

• Hemoglobin [14 to 18 g/dL (140 to 180 g/L)]
• Potassium [3.5 to 5.0 mEq/L (3.5 to 5.0 mmol/L)]
• White Blood Cell [5,000 to 10,000/mm3 (5 to 10 x 109/L)]

Rationale

A. In the early phase following a burn injury, there is increased capillary permeability due to the release of inflammatory mediators. This results in fluid shifting from the intravascular space into the interstitial space (capillary leaking), leading to hypovolemia and decreased tissue perfusion. Administering crystalloid fluids helps to restore intravascular volume (fluid resuscitation) and improve tissue perfusion.

B. Burn injuries can lead to increased evaporative water loss through damaged skin (insensible water loss). Crystalloid fluids help to replace this lost fluid and maintain adequate hydration status in the client.

C. In severe burn injuries, there may be a need for blood transfusions due to hemorrhage or ongoing blood loss. Crystalloid fluids can help to extend plasma volume temporarily until blood products are available for transfusion, thereby supporting circulatory stability.

D. Burn injuries can disrupt electrolyte balance due to fluid shifts and tissue damage. Crystalloid fluids contain electrolytes (such as sodium and chloride) that help to restore and maintain electrolyte balance in the body.

Rationale

A. Monitoring blood glucose levels is important, especially in critically ill patients, as hyperglycemia can worsen outcomes in septic shock. However, it is not the most critical intervention in the immediate management of septic shock.

B. Monitoring intake and output (I/O) is essential for assessing fluid balance, which is crucial in managing septic shock. Maintaining a strict I/O helps in determining fluid resuscitation needs and evaluating response to treatment. This intervention is important but may not be the most critical initially.

C. Assessing warmth of extremities is important as it helps in evaluating peripheral perfusion, which can be compromised in septic shock. Cold extremities can indicate poor tissue perfusion and may prompt the need for interventions such as fluid resuscitation.

D. Keeping the head of the bed elevated to 45 degrees is a specific intervention aimed at improving oxygenation and respiratory function, particularly in patients who may be mechanically ventilated or at risk of respiratory compromise. While this is an important intervention, it is not directly related to managing septic shock itself.
