Which classification does reflexology fall under within complementary and alternative medicine?

A. Perform a skin assessment:While skin integrity is important for all patients, it is not the priority intervention for a suspected gastrointestinal infection. A skin assessment does not prevent the transmission of Clostridioides difficilespores to other patients or staff. It is a secondary task in the context of infection control.

B. Implement standard precautions:Standard precautions are used for all patients but are insufficient to contain the hardy spores of C. diff. These spores are resistant to many common disinfectants and require specific barrier methods. Relying only on standard precautions increases the risk of an institutional outbreak.

C. Offer oral rehydration solution:Managing fluid loss is a supportive measure for diarrhea, but it does not address the primary need for source control. The nurse's first priority must be preventing the spread of the pathogen within the healthcare environment. Hydration is important but follows the implementation of isolation protocols.

D. Enforce contact precautions:C. diffis highly transmissible via the feco-oral route and requires gloves, gowns, and dedicated equipment to prevent cross-contamination. Contact precautions are the specific evidence-based intervention required to contain the infectious spores. This protects the safety of the unit and other vulnerable clients.

A. Elevated pH: A high pH (alkalemia) indicates a decrease in hydrogen ion concentration, which is characteristic of alkalosis. Metabolic acidosis is defined by a low arterial pH, typically less than 7.35. The acidic state results from either an accumulation of fixed acids or a loss of base.

B. Elevated PaO2: Partial pressure of arterial oxygen measures the amount of oxygen dissolved in the blood and is a marker of oxygenation. It is not a direct component of the acid-base balance equation. While hypoxia can cause metabolic acidosis (via lactic acid), an elevated PaO2 is not a characteristic finding.

C. Decreased bicarbonate: Bicarbonate (HCO3-) is the primary buffer in the extracellular fluid. In metabolic acidosis, bicarbonate levels drop as it is consumed while neutralizing excess hydrogen ions or because it is lost through the kidneys or GI tract. A value below 22 mEq/L is a hallmark of this condition.

D. Increased PaCO2: An elevated partial pressure of carbon dioxide indicates respiratory acidosis or a compensatory response to metabolic alkalosis. In metabolic acidosis, the body typically tries to compensate by hyperventilating to blow off CO2, which would result in a decreased PaCO2. This is the body's respiratory compensation mechanism.
