A nurse who serves on an infection control committee is assessing the adequacy of environmental controls against infection.
What does the nurse know to be the first line of defense in medical asepsis?
Isolation or barrier procedures.
Standard precautions.
Hand hygiene techniques.
Routine cleaning of client rooms.
The Correct Answer is C
Hand hygiene techniques are the first line of defense in medical asepsis because they prevent the transmission of microorganisms from one person or object to another. Hand hygiene techniques include washing hands with soap and water or using an alcohol-based handrub.
Choice A is wrong because isolation or barrier procedures are not the first line of defense in medical asepsis, but rather a way of preventing the spread of infection to other patients or health care workers when a patient has a known or suspected infection.
Choice b is wrong because the nature of detergent used on the unit is not the first line of defense in medical asepsis, but rather a factor that affects the effectiveness of cleaning and disinfection of surfaces and equipment.
Choice D is wrong because the ventilation system type is not the first line of defense in medical asepsis, but rather a factor that affects the quality of air and the risk of airborne transmission of microorganisms.

Correct Answer is A
Explanation
Formed stool two times per day, every day, for one week. This indicates that bowel training is attaining the desired outcome because it shows regularity and consistency of bowel movements without the use of laxatives or enemas.
Choice B is wrong because soap sud enemas are not recommended for bowel training as they can irritate the bowel and cause fluid and electrolyte imbalance.
Choice C is wrong because continued use of laxatives can inhibit the natural defecation reflexes and cause dependency.
Choice D is wrong because a formed, soft stool at regular intervals without the use of a laxative is a normal defecation pattern, not an indication of fecal incontinence.
Correct Answer is D
Explanation
temperature 101.8° F(38.8° C), BP 100/60 mm Hg, pulse 98/min, RR 28/min. This set of vital signs indicates that the client may have an infection or sepsis, which are potential complications of an open cholecystectomy. The client has a fever, tachycardia, tachypnea, and hypotension, which are signs of systemic inflammatory response syndrome (SIRS).
Choice A is wrong because it shows mild hypothermia, hypotension, and tachycardia, which could be due to dehydration or blood loss, but not necessarily infection.
Choice B is wrong because it shows a slight fever, normal blood pressure, and bradycardia, which could be due to pain or medication, but not infection.
Choice C is wrong because it shows a low-grade fever, normal blood pressure and pulse, and mild tachypnea, which could be due to inflammation or dehydration, but not infection.
