A post-op patient has a sudden decrease in SpO2 levels to 88%. What should be the nurse's first action?

A. Assist the patient in setting recovery goals: Goal setting falls under the categories of self-actualization or self-esteem within the hierarchical framework. While important for long-term rehabilitation, these needs are secondary during the acute phase of a medical crisis. They cannot be addressed until the underlying physiological stability is secured.

B. Prioritize fluid resuscitation and wound care: Physiological needs represent the most fundamental level of the hierarchy and must be met to ensure survival. Severe burns cause massive fluid shifts and loss of skin integrity, leading to hypovolemic shock and electrolyte imbalances. Addressing these immediate life-threatening deficits is the highest priority.

C. Encourage family visits to improve emotional support: Emotional support and belongingness are mid-level needs that contribute to psychological well-being. Although family involvement is beneficial for the patient's holistic recovery, it does not take precedence over physiological stabilization. These needs are addressed once the patient is no longer medically unstable.

D. Ensure a safe and secure environment: Safety and security form the second level of the hierarchy, just above physiological requirements. While protecting the patient from further injury or infection is crucial, it is contingent upon the primary restoration of physiological homeostasis. Fluid resuscitation is more immediate than environmental safety.

A. Restrict vitamin D supplements:Vitamin D is essential for the intestinal absorption of calcium; therefore, restricting it would exacerbate the patient's hypocalcemic state. Vitamin D and calcium have a synergistic relationship required for bone mineralization and neuromuscular function. Supplementation is usually encouraged rather than restricted.

B. Avoid foods high in potassium:Potassium and calcium are different electrolytes with distinct physiological roles. Restricting potassium does not assist in raising serum calcium levels and could lead to other imbalances like hypokalemia. Dietary management for hypocalcemia should focus specifically on calcium and vitamin D intake.

C. Include processed foods in the diet:Processed foods are often high in sodium and phosphorus, which can interfere with calcium balance or lead to increased urinary calcium excretion. These foods typically lack the dense micronutrient profile needed for therapeutic electrolyte replacement. They are generally discouraged in a heart-healthy or mineral-balanced diet.

D. Increase consumption of dairy products and leafy greens:Dairy products are rich in bioavailable calcium, while certain leafy greens provide supplemental amounts of this essential mineral. Adequate calcium intake is vital for preventing tetany, seizures, and cardiac arrhythmias associated with low serum levels. This is the primary dietary intervention for restoring mineral homeostasis.
