The nurse is caring for a client who fell through the ice while ice skating. To prevent further decrease in body temperature, which action should the nurse take first?

• Disinfecting a client's counter before administering oral medications: This practice reduces the number of microorganisms on surfaces to prevent infection, which is the principle of medical asepsis. It focuses on cleanliness and reducing contamination rather than creating a completely sterile environment.

• Covering the client and surrounding area with sterile drapes: Sterile drapes create a sterile field and prevent contamination of surgical or invasive sites. This is a key component of surgical asepsis, ensuring that instruments, supplies, and the environment remain free from microorganisms during procedures.

• Covering mouth and nose with a sleeve or elbow when coughing or sneezing: This prevents the spread of pathogens via droplets and maintains a clean environment. It is a basic principle of medical asepsis, which aims to reduce infection transmission through routine hygiene practices.

• Allowing only sterile-to-sterile contact: Maintaining a sterile field requires that sterile items only touch other sterile items. This is fundamental to surgical asepsis, preventing introduction of microorganisms during invasive procedures. Any break in sterile technique increases the risk of infection.

• Using sterile packaging for instruments and supplies: Sterile packaging preserves sterility until use, which is critical for surgical asepsis. It ensures that instruments and supplies remain free from microorganisms until the moment of use in invasive procedures.

• Using an autoclave to sterilize surgical instruments: Autoclaving uses high-pressure steam to destroy all microorganisms, achieving complete sterility. This process is a core component of surgical asepsis, making instruments safe for invasive procedures.

A. Kussmaul respirations: These are deep, rapid, and labored respirations typically associated with metabolic acidosis, such as diabetic ketoacidosis. They do not include alternating periods of apnea and hyperventilation, so they do not match the described pattern.

B. Cheyne-Stokes respirations: This breathing pattern is characterized by cyclic periods of increasing and decreasing depth of respiration, followed by temporary apnea. It commonly occurs in clients with advanced heart failure, neurological injury, or nearing end-of-life, making it consistent with hospice clients exhibiting irregular breathing.

C. Agonal breathing: Agonal respirations are irregular, gasping breaths often seen in severe hypoxia or near death. They are typically ineffective for gas exchange and not part of a regular cyclical pattern.

D. Biot's respirations: Biot’s respirations consist of groups of quick, shallow breaths followed by irregular pauses. They are usually associated with increased intracranial pressure or medullary damage rather than end-of-life breathing patterns.
