Which intervention should a nurse take when a patient on antibiotic therapy develops diarrhea and is suspected of having C. diff?

A. Administer diuretics:Diuretics are primarily used to treat fluid volume excess or hypertension by increasing renal excretion of water and sodium. They do not address the underlying cause of respiratory alkalosis, which is an excessive loss of carbon dioxide. They are inappropriate for managing primary acid-base disturbances of respiratory origin.

B. Initiate fluid restriction:Restricting fluid intake is a management strategy for conditions like SIADH or congestive heart failure. It has no impact on the partial pressure of arterial carbon dioxide or the alveolar ventilation rate. This intervention is unrelated to the physiological correction of alkalotic pH levels.

C. Encourage the patient to breathe into a paper bag:Respiratory alkalosis is caused by hyperventilation, which leads to hypocapnia and an elevated blood pH. Rebreathing exhaled air increases the inspiratory concentration of carbon dioxide, helping to restore normal PaCO2 and pH. This is a classic intervention for non-organic, anxiety-induced hyperventilation.

D. Provide supplemental oxygen therapy:Oxygen is indicated for hypoxemia but does not correct a high pH caused by low carbon dioxide levels. In some cases, providing high-flow oxygen can actually encourage further hyperventilation if not monitored correctly. The primary goal in alkalosis is carbon dioxide retention rather than oxygen supplementation.

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.
