Which term would the nurse use when extracellular fluid and intracellular fluid have the same osmolality?

Choice A: 3% Saline
3% Saline is a hypertonic solution, meaning it has a higher concentration of solutes compared to the blood plasma. It is typically used in critical care settings for specific conditions such as severe hyponatremia or cerebral edema. Administering 3% Saline to a patient with a fluid deficit who requires isotonic fluid replacement would not be appropriate because it could lead to cellular dehydration and other complications due to its high osmolarity.
Choice B: Saline 0.45%
Saline 0.45%, also known as half-normal saline, is a hypotonic solution. It has a lower concentration of solutes compared to blood plasma and is used to treat patients with hypernatremia or those who need to be rehydrated without adding too much sodium. However, it is not suitable for isotonic fluid replacement because it can cause cells to swell and potentially burst due to the influx of water into the cells.
Choice C: Saline 0.9%
Saline 0.9%, also known as normal saline, is an isotonic solution. It has the same concentration of solutes as blood plasma, making it ideal for fluid replacement in patients with a fluid deficit. Normal saline is commonly used to expand the extracellular fluid volume without causing significant shifts in fluid between compartments. This makes it the appropriate choice for isotonic fluid replacement.
Choice D: Dextrose 10%
Dextrose 10% is a hypertonic solution used primarily for providing calories in patients who need parenteral nutrition or for treating severe hypoglycemia. It is not suitable for isotonic fluid replacement because its high glucose content can lead to osmotic diuresis and fluid shifts that are not desirable in patients needing isotonic fluids.

Choice A: Properly cleaning all reusable equipment once each day

While cleaning reusable equipment is important, it should be done after each use, not just once a day. This ensures that any potential pathogens are removed before the equipment is used on another patient, thereby preventing cross-contamination.

Choice B: Appropriately using PPE

This is a correct answer. Personal Protective Equipment (PPE) such as gloves, masks, gowns, and eye protection are essential in preventing the spread of infection. Proper use of PPE helps protect both healthcare workers and patients from exposure to infectious agents.

Choice C: Ensuring all environmental surfaces are properly cleaned, disinfected, and maintained

This is another correct answer. Regular cleaning and disinfection of environmental surfaces, such as bed rails, doorknobs, and medical equipment, are crucial in preventing the spread of infections. Maintaining a clean environment reduces the risk of healthcare-associated infections.

Choice D: Avoiding all invasive interventions

Avoiding invasive interventions is not a practical or realistic approach to preventing infections. While minimizing unnecessary invasive procedures can reduce infection risk, many invasive interventions are necessary for patient care. Instead, proper aseptic techniques should be used during these procedures to prevent infections.

Choice E: Performing hand washing or using an alcohol-based hand sanitizer before and after patient contact or procedures

This is also a correct answer. Hand hygiene is one of the most effective measures to prevent the spread of infections. Washing hands with soap and water or using an alcohol-based hand sanitizer before and after patient contact or procedures significantly reduces the transmission of pathogens.
